                                               7.375% per year from the date of issuance to,
                                               but excluding, June 15, 2003, computed on the

                                               will be computed on the basis of the actual
                                               number of days in the applicable floating
                                               rate reset period over a 360-day year.

                                  THE COMPANY

    We are a global power company incorporated in Delaware on January 28, 1981.
We are committed to serving the world's need for electricity and other services
in a socially responsible way.

    We have been successful in growing our business and serving additional
customers by, in part, participating in competitive bidding under privatization
initiatives. We have been particularly interested in acquiring existing
businesses or assets in electricity markets that are promoting competition and
eliminating rate of return regulation. Sellers generally seek to complete such
transactions in less than one year, much quicker than the time periods
associated with greenfield development and usually require payment in full on
transfer. We believe that our experience in competitive markets and our
worldwide integrated group structure, with our significant geographic coverage
and presence, enable us to react quickly and creatively in these situations. Our
significant growth has resulted in generating capacity of 42,133 megawatts or MW
at December 31, 2000, with a total of 141 plants in operation.

    Our ownership portfolio of power facilities includes new plants constructed
for such purposes as well as existing power plants acquired through
competitively bid privatization initiatives and negotiated acquisitions. In the
electricity generation business, we now own and operate (entirely or in part) a
diverse portfolio of electric power plants (including those within integrated
distribution companies) with, as of December 31, 2000, capacity of 42,133 MW. Of
that total, 38% are fueled by coal or petroleum coke, 18% are fueled by natural
gas, 33% are hydroelectric facilities, 4% are fueled by oil, and the remaining
7% are capable of using multiple fossil fuels. A majority of our sales of
electricity are made to customers (generally electric utilities or regional
electric companies), on a wholesale basis for further resale to end users. This
is referred to as the electricity "generation" business. Sales by these
generation companies are made under long-term contracts from power plants owned
by our subsidiaries and affiliates as well as directly into regional electricity
markets without contracts.

    We also sell electricity directly to end users such as commercial,
industrial, governmental and residential customers through our "distribution"
business. We have ownership interests in distribution companies in Argentina,
India, the United States, Brazil, Venezuela, El Salvador, Dominican Republic,
and The Republic of Georgia. We also have assumed management control of a heat
and electricity distribution business in Kazakhstan. We also have three
subsidiaries in the United States that serve retail customers in those states
that have introduced a competitive market for the sale of electricity to end
users.

                                USE OF PROCEEDS

    We expect to receive aggregate net proceeds from the sale of the Senior
Notes and the ROARS of $596,968,000, after deducting underwriting discounts and
offering expenses payable by us. This estimate includes the consideration we
will receive for the option granted to the Remarketing Dealer to purchase and
remarket the ROARS.

    We intend to use the net proceeds from this offering (i) to temporarily
repay amounts outstanding under our revolving credit agreement, (ii) to fund all
or a portion of the purchase price of Thermo Ecotek Corporation and (iii) for
general corporate purposes. The revolver bears interest at a weighted average
interest rate of LIBOR + 2% and matures in March 2003. As of March 31, 2001,
$440 million was outstanding under our revolving credit agreement.

                          DESCRIPTION OF SENIOR NOTES

    The Senior Notes will be issued under an indenture, dated as of December 8,
1998, as supplemented by a supplemental indenture, to be dated as of June 5,
2001, each between AES and Bank One, National Association (formerly known as The
First National Bank of Chicago), the trustee (the "Trustee") (collectively
referred to in this section as the "Indenture"). The following summary of the
terms of the Senior Notes and certain provisions of the Indenture does not
purport to be complete and is subject to, and is qualified in its entirety by
reference to, all of the provisions of the Indenture, including the definitions
in the Indenture of certain terms. Wherever particular sections or defined terms
of the Indenture are referred to, such sections or defined terms are
incorporated herein by reference. A copy of the Indenture is available for
inspection at the office of the Trustee.

    As used in this Section, the term "AES" means The AES Corporation, and does
not include any of its subsidiaries.

    The Indenture does not limit the aggregate principal amount of indebtedness
which may be issued thereunder and provides that senior debt securities may be
issued thereunder from time to time in one or more series. The Senior Notes
constitute a separate series under the Indenture.

GENERAL

    The Senior Notes will be issued as a separate series of senior debt
securities under the Indenture. The Senior Notes will not be limited in
aggregate principal amount. Additional Senior Notes may be issued under the
Indenture from time to time as part of this series of Senior Notes.

    The entire principal amount of the Senior Notes will mature and become due
and payable, together with any accrued and unpaid interest thereon, on June 15,
2008. The Senior Notes are not subject to any sinking fund provision.

INTEREST

    Each Senior Note shall bear interest at 8.750% per year from the date of
original issuance, payable semiannually on June 15 and December 15 of each year
to the person in whose name such Senior Note is registered at the close of
business on the fifteenth calendar day prior to such interest payment date. The
initial interest payment date is December 15, 2001. The amount of interest
payable will be computed on the basis of a 360-day year of twelve 30-day months.
In the event that any date on which interest is payable on the Senior Notes is
not a Business Day, then payment of the interest payable on such date will be
made on the next succeeding day which is a Business Day (and without any
interest or other payment in respect of any such delay), except that, if such
Business Day is in the next succeeding calendar year, such payment shall be made
on the immediately preceding Business Day, in each case with the same force and
effect as if made on such date.

OPTIONAL REDEMPTION

    The Senior Notes are subject to redemption upon not less than 30 nor more
than 60 days' notice by mail, at any time, as whole or in part, at our election,
at a price equal to the sum of (i) 100% of the principal amount thereof plus
accrued interest to the redemption date plus (ii) the Make-Whole Amount, if any.

    The term "Make-Whole Amount" shall mean, in connection with any optional
redemption of any Senior Note, the excess, if any, of (i) the aggregate present
value as of the date of such redemption of each dollar of principal being
redeemed and the amount of interest (exclusive of interest accrued to the
redemption date) that would have been payable in respect of such dollar if such
prepayment had not been made, determined by discounting, on a semiannual basis,
such principal and interest at the Reinvestment Rate (determined on the Business
Day preceding the date of such redemption) from the respective dates on which
such principal and interest would have been payable if such payment had not been
made, over (ii) the aggregate principal amount of the Senior Notes being
redeemed.

                                      S-8

    The term "Reinvestment Rate" shall mean 0.50% (one-half of one percent) plus
the arithmetic mean of the yields under the respective headings "This Week" and
"Last Week" published in the Statistical Release under the caption "Treasury
Constant Maturities" for the maturity (rounded to the nearest month)
corresponding to the maturity of the principal being prepaid. If no maturity
exactly corresponds to such maturity, yields for the two published maturities
most closely corresponding to such maturity shall be calculated pursuant to the
immediately preceding sentence and the Reinvestment Rate shall be interpolated
or extrapolated from such yields on a straight-line basis, rounding in each of
such relevant periods to the nearest month. For the purpose of calculating the
Reinvestment Rate, the most recent Statistical Release published prior to the
date of determination of the Make-Whole Amount shall be used.

    The term "Statistical Release" shall mean the statistical release designated
"H.15(519)" or any successor publication which is published weekly by the
Federal Reserve System and which establishes yields on actively traded U.S.
government securities adjusted to constant maturities or, if such statistical
release is not published at the time of any determination under the Indenture,
then such other reasonably comparable index which shall be designated by us.

CERTAIN COVENANTS OF AES

    RESTRICTIONS ON SECURED DEBT.  If AES shall incur, issue, assume or
guarantee any indebtedness for borrowed money represented by notes, bonds,
debentures or other similar evidences of indebtedness, secured by a mortgage,
pledge or other lien on any Principal Property (as defined below) or any capital
stock or indebtedness held directly by AES of any Subsidiary of AES, AES shall
secure the Senior Notes equally and ratably with (or prior to) such
indebtedness, so long as such indebtedness shall be so secured, unless after
giving effect thereto the aggregate amount of all such indebtedness so secured,
together with all Attributable Debt (as defined below) in respect of sale and
leaseback transactions involving Principal Properties, would not exceed 15% of
the Consolidated Net Assets (as defined below) of AES. This restriction will not
apply to, and there shall be excluded in computing secured indebtedness for the

Subsidiary of AES, (b) liens on property of, or on any shares of stock or debt
of, any corporation existing at the time such corporation becomes a Subsidiary,
(c) liens in favor of AES or any Subsidiary, (d) liens in favor of U.S. or

first date on which any Senior Notes issued under the Indenture are
authenticated by the Trustee, (g) liens under one or more credit facilities for
indebtedness in an aggregate principal amount not to exceed $900 million at any
time outstanding, (h) liens incurred in connection with pollution control,
industrial revenue or similar financings, and (i) any extension, renewal or
replacement of any debt secured by any liens referred to in the foregoing
clauses (a) through (h), inclusive. As of the date of this prospectus
supplement, AES does not own or lease any Principal Property.

    The term "Principal Property" means any building, structure or other
facility (together with the land on which it is erected and fixtures comprising
a part thereof) used primarily for manufacturing, processing, research,
warehousing or distribution, owned or leased by AES and having a net book value
in excess of 2% of Consolidated Net Assets, other than any such building,
structure or other facility or portion thereof which is a pollution control
facility financed by state or local governmental obligations or which the
principal executive officer, president and principal financial officer of AES
determine in good faith is not of material importance to the total business
conducted or assets owned by AES and its Subsidiaries as an entirety.

                                      S-9

    The term "Consolidated Net Assets" means the aggregate amount of assets
(less reserves and other deductible items) after deducting current liabilities,
as shown on the consolidated balance sheet of AES and its Subsidiaries contained
in the latest annual report to the stockholders of AES and prepared in
accordance with generally accepted accounting principles.

    The term "Attributable Debt" means the present value (discounted at the rate
of 8.750% per year compounded monthly) of the obligations for rental payments
required to be paid during the remaining term of any lease of more than 12
months.

    "Subsidiary" means, with respect to any person, any corporation, association
or other business entity of which a majority of the capital stock or other
ownership interests having ordinary voting power to elect a majority of the
board of directors or other persons performing similar functions are at the time
directly or indirectly owned by such person.

    RESTRICTIONS ON SALES AND LEASEBACKS. AES may not enter into any sale and
leaseback transaction involving any Principal Property, the acquisition or
completion of construction and commencement of full operation of which has
occurred more than 180 days prior thereto, unless (a) AES could incur a lien on
such property under the restrictions described above under "Restrictions on
Secured Debt" in an amount equal to the Attributable Debt with respect to the
sale and leaseback transaction without equally and ratably securing the Senior
Notes or (b) AES, within 180 days after the sale or transfer by AES, applies to
the retirement of its funded debt (defined as indebtedness for borrowed money
having a maturity of, or by its terms extendible or renewable for, a period of
more than 12 months after the date of determination of the amount thereof) an
amount equal to the greater of (i) the net proceeds of the sale of the Principal
Property sold and leased pursuant to such arrangement or (ii) the fair market
value of the Principal Property so sold and leased (subject to credits for
certain voluntary retirements of funded debt) as determined by the Board of
Directors of AES.

EVENTS OF DEFAULT

    In addition to the Events of Default set forth in the accompanying
prospectus, an Event of Default will occur with respect to the Senior Notes if
an event of default, as defined in any indenture or instrument evidencing or
under which AES has at the date of the Indenture or shall thereafter have
outstanding any indebtedness, shall happen and be continuing and either
(a) such default results from the failure to pay the principal of such
indebtedness in excess of $50 million at final maturity of such indebtedness or
(b) as a result of such default the maturity of such indebtedness shall have
been accelerated so that the same shall be or become due and payable prior to
the date on which the same would otherwise have become due and payable, and such
acceleration shall not be rescinded or annulled within 60 days and the principal
amount of such indebtedness, together with the principal amount of any other
indebtedness of AES in default, or the maturity of which has been accelerated,
aggregates $50 million or more; provided that the Trustee shall not be charged
with knowledge of any such default unless written notice thereof shall have been
given to the Trustee by AES, by the holder or an agent of the holder of any such
indebtedness, by the trustee then acting under any indenture or other instrument
under which such default shall have occurred, or by the holders of not less than
25% in the aggregate principal amount of the Senior Notes at the time
outstanding; and provided further that if such default shall be remedied or
cured by AES or waived by the holder of such indebtedness, then the Event of
Default under the Indenture by reason thereof shall be deemed likewise to have
been remedied, cured or waived without further action on the part of the
Trustee, any holder of Senior Notes or any other person.

FORM, DENOMINATION AND REGISTRATION

    The Senior Notes will be issued in fully registered form, without coupons,
in denominations of $1,000 in principal amount and integral multiples thereof.
The Senior Notes will be evidenced by one or more global securities

                                      S-10

(each, a "Global Senior Note"). The Global Senior Notes will be deposited with
or on behalf of The Depository Trust Company ("DTC") or its nominee. Except as

successor of DTC or its nominee. See "Description of Debt Securities--Book-Entry
Systems" in the accompanying prospectus.

PAYMENTS OF PRINCIPAL AND INTEREST; TRANSFER OR EXCHANGE

(including principal, premium, if any, and interest) held of record by DTC or
its nominee be made in same day funds. Payments in respect of the Senior Notes
held of record by holders other than DTC or its nominee may, at the option of
AES, be made by check and mailed to such holders of record as shown on the
register for the Senior Notes. The Senior Notes may be surrendered for transfer
or exchange at the office of the Trustee in New York, New York.

GOVERNING LAW

banking transactions with the Trustee in the ordinary course of business.

OTHER PROVISIONS

    See the accompanying prospectus for a description of certain additional
provisions of the Indenture, including Events of Default thereunder and
provisions for amendments and modifications thereof.

                                      S-11

                              DESCRIPTION OF ROARS

    The ROARS will be issued under an indenture, dated as of December 8, 1998,
as supplemented by a supplemental indenture, to be dated as of June 5, 2001,
each between AES and Bank One, National Association (formerly known as The First
National Bank of Chicago), the trustee (the "Trustee") (collectively referred to
in this section as the "Indenture"). The following summary of the terms of the
ROARS and certain provisions of the Indenture does not purport to be complete
and is subject to, and is qualified in its entirety by reference to, all of the
provisions of the Indenture, including the definitions in the Indenture of
certain terms. Wherever particular sections or defined terms of the Indenture
are referred to, such sections or defined terms are incorporated herein by
reference. A copy of the Indenture is available for inspection at the office of
the Trustee.

    As used in this Section, the term "AES" means The AES Corporation, and does
not include any of its subsidiaries.

    The Indenture does not limit the aggregate principal amount of indebtedness
which may be issued thereunder and provides that senior debt securities may be
issued thereunder from time to time in one or more series. The ROARS constitute
a separate series under the Indenture.

GENERAL

    The ROARS will initially be limited to $200,000,000 aggregate principal
amount. However, additional ROARS may be issued under the Indenture from time to
time as part of this series of ROARS. The ROARS are scheduled to mature on
June 15, 2013, but such maturity date may be adjusted to a date which shall be
no later than the tenth anniversary of the Fixed Rate Remarketing Date (as
defined below), which shall not be later than June 15, 2014. We may be required
to redeem, the ROARS before that maturity date as described in "Mandatory
Redemption" below. We may also redeem all of the ROARS on any Remarketing Date,
as described in "Optional Redemption" and some or all of the ROARS at any time
after the Fixed Rate Remarketing Date as described in "Post-Remarketing Optional
Redemption" below. The ROARS may also be purchased by the Remarketing Dealer as
described in "Mandatory Tender" below.

    The ROARS are not entitled to any sinking fund.

    The ROARS will initially be issued only in registered, book-entry form, in
denominations of $1,000 and any integral multiple of $1,000 as described under
"Settlement," "Form, Denomination and Registration," and "Description of Debt
Securities--Book-Entry Systems" in the accompanying prospectus. We will issue
global securities in denominations that together equal the total principal
amount of the outstanding ROARS.

    If any interest, principal or other payment date of the ROARS (including any
payment date in connection with the mandatory tender or any mandatory or
optional redemption as described below) that then accrue interest at a fixed
rate does not fall on a Business Day (as defined below), a payment otherwise
payable on that day will be made on the next succeeding Business Day. It will
have the same effect as if made on the actual payment date, and no interest will
accrue for the period from and after such payment date. In the case of any such
payment with respect to the ROARS that then accrue interest at a floating rate,
interest will accrue from such originally scheduled payment date to but
excluding such next succeeding Business Day (except in the case of an interest
payment at maturity, in which case no interest will accrue from and after the
maturity date).

    "Business Day" means any day other than a Saturday or Sunday or a day on
which banking institutions in New York City are authorized or obligated by law
or executive order to close.

    "London Business Day" means any day on which dealings in U.S. dollars are
transacted in the London Inter-Bank Market.

    We have agreed with the Remarketing Dealer that we will not cause or permit
the terms or provisions of the ROARS (or the

                                      S-12

related supplemental indenture) to be modified in any way, and may not make open
market or other purchases of the ROARS prior to the first Remarketing Date,
without the prior written consent of the Remarketing Dealer.

    The ROARS will bear interest at 7.375% per year, from their date of issuance
to, but excluding, June 15, 2003. We will pay interest during this period
semiannually on June 15 and December 15, beginning on December 15, 2001.

    "Remarketing Date(s)" means June 15, 2003, assuming the Remarketing Dealer
has elected to purchase the ROARS and we have not elected to exercise our
Floating Period Option (as defined in "Floating Rate Period" below) or, if we
have elected to exercise our Floating Period Option, each of June 15, 2003 and
the Floating Period Termination Date (as defined in "Floating Rate Period"
below).

    Unless we have chosen to redeem or are required to redeem the ROARS, we will
pay interest on the ROARS, accruing from the Fixed Rate Remarketing Date (as
defined below), semiannually on each day that is a six-month anniversary of such
date. Interest on the ROARS from the Fixed Rate Remarketing Date will be
computed on the basis of a 360-day year consisting of twelve 30-day months.

    Interest on the ROARS accruing during any Floating Rate Reset Period (as
defined in "Floating Rate Period" below) will be payable on the next following
Reference Rate Reset Date and on the Floating Period Termination Date. Interest
on the ROARS during the Floating Rate Period (as defined in "Floating Rate
Period" below) will be computed on the basis of the actual number of days in
such Floating Rate Reset Period over a 360-day year.

    Interest payable on any interest payment date will be payable to the persons
in whose names the ROARS are registered at the close of business on the
fifteenth calendar day (whether or not a Business Day) immediately preceding the
related interest payment date.

    "Fixed Rate Remarketing Date" means June 15, 2003, assuming the Remarketing
Dealer has elected to purchase the ROARS and we have not elected to exercise our
Floating Period Option, or the subsequent Remarketing Date on which the Floating
Period Termination Date occurs in the event that we have elected to exercise our
Floating Period Option.

    Interest payments will be in the amount of interest accrued from and
including the next preceding interest payment date (or from and including the
date of issuance if no interest has been paid or duly provided with respect to
the ROARS) to but excluding, the relevant interest payment date, Remarketing
Date or the maturity date, as the case may be.

INTEREST RATE TO MATURITY

    If the Remarketing Dealer elects to purchase the ROARS on the first
Remarketing Date, then by 3:30 p.m., New York City time, on the third Business
Day immediately preceding such Remarketing Date (the "Floating Rate Spread
Determination Date" or the "Fixed Rate Determination Date," depending on the
following election, and each, a "Determination Date"), the Remarketing Dealer
will determine either (a) the Floating Rate Spread (as defined in "Floating Rate
Period" below) in the case where we have elected to exercise our Floating Period
Option or (b) the Interest Rate to Maturity (as defined below) to the nearest
one hundredth of one percent per year, unless we have chosen to redeem, or are
required to redeem, the ROARS. Each Floating Period Interest Rate (as defined in
"Floating Rate Period" below) will equal the sum of the Reference Rate (as
defined in "Floating Rate Period" below) and the Floating Rate Spread (as
defined in "Floating Rate Period" below). The Interest Rate to Maturity will be
equal to the sum of 5.500% (the "Base Rate") and the Applicable Spread (as
defined below), which will be based on the Dollar Price (as defined below) of
the ROARS. The Floating Period Interest Rate, the Interest Rate to Maturity and
the Dollar Price for the ROARS as announced by the Remarketing Dealer, absent
manifest error, will be binding and conclusive upon the beneficial owners, us
and the Trustee.

                                      S-13

    For this purpose, the following terms have the following meanings:

ROARS, obtained by the Remarketing Dealer by 3:30 p.m., New York City time, on
the Fixed Rate Determination Date, from the Fixed Rate Bids quoted to the
Remarketing Dealer by up to five Reference Corporate Dealers.

    A "Fixed Rate Bid" means an irrevocable offer to purchase the aggregate
outstanding principal amount of the ROARS at the Dollar Price, but assuming:

by the applicable Reference Corporate Dealer.

    "Comparable Treasury Issues" for the ROARS means the U.S. Treasury security
or securities selected by the Remarketing Dealer, as of the first Determination
Date, as having an actual or interpolated maturity or maturities comparable to

Date:

    (1) the offer prices for the Comparable Treasury Issues (expressed, in each
case, as a percentage of its principal amount) at 12:00 noon, New York City

such other page as may replace "Telerate Page 500") or

    (2) if such page (or any successor page) is not displayed or does not
contain such offer prices on such Determination Date, the average of the
Reference Treasury Dealer Quotations for such Determination Date, after

Treasury Issues, as may replace Dow Jones Markets.

    "Reference Treasury Dealer Quotations" means, with respect to each Reference
Treasury Dealer, the offer prices for the Comparable Treasury Issues (expressed

City time, on the first Determination Date.

    "Dollar Price" means, with respect to the ROARS, (1) the principal amount of
the ROARS, plus (2) the premium equal to the excess, if any, of (A) the present
value, as of the first Remarketing Date, of the Remaining Scheduled Payments for
such ROARS, discounted to the first Remarketing Date on a semiannual basis
(assuming a 360-day year consisting of twelve 30-day months) at the Treasury
Rate, over (B) the principal amount of the ROARS.

    "Fixed Rate Determination Date" means the third Business Day prior to the
Fixed Rate Remarketing Date.

    "Reference Corporate Dealer" means each of up to five leading dealers of

Banc of America Securities LLC, if Banc of America Securities LLC is then the
Remarketing Dealer.

                                      S-14

    "Reference Treasury Dealer" means each of up to five primary U.S. government
securities dealers (each, a "Primary Treasury Dealer") to be selected by us, and
their respective successors; PROVIDED that if any of the foregoing ceases to be,

is then the Remarketing Dealer.

principal and interest on the ROARS, calculated at the Base Rate, that would be

2013; PROVIDED that if such Remarketing Date is not an interest payment date,
the amount of the next succeeding scheduled interest payment, calculated at the
Base Rate, will be reduced by the amount of interest accrued, calculated at the
Base Rate only, to the first Remarketing Date.

    "Treasury Rate", with respect to the first Remarketing Date, means the rate
per year equal to the semiannual equivalent yield to maturity or interpolated
(on a day count basis) yield to maturity of the Comparable Treasury Issues,
assuming a price for the Comparable Treasury Issues (expressed as a percentage
of their principal amounts) equal to the Comparable Treasury Price for such
Remarketing Date.

NOTIFICATION OF INTEREST RATE TO MATURITY

    If the Remarketing Dealer elects to purchase the ROARS, the Remarketing
Dealer will notify us, the Trustee and DTC by telephone, confirmed in writing
(which may include facsimile or other electronic transmission), by 4:00 p.m.,
New York City time, on the Fixed Rate Determination Date of the Interest Rate to
Maturity effective from and including the Fixed Rate Remarketing Date.

MATURITY DATE ADJUSTMENT

    We may, at our option, elect to modify the maturity date of the ROARS by
designating a date which is an anniversary of the Fixed Rate Remarketing Date
but is not later than the tenth anniversary of such Fixed Rate Remarketing Date,
which shall not be later than June 15, 2014. Notice of such designation must be
given no later than 4:00 p.m., New York City time, on the fourth Business Day
prior to the Fixed Rate Remarketing Date.

FLOATING RATE PERIOD

    Following the Remarketing Dealer's election to purchase the ROARS in
connection with the first Remarketing Date, but prior to 4:00 p.m. on the fourth
Business Day immediately preceding the first Remarketing Date (the "Floating
Period Notification Date"), we may elect to exercise our Floating Period Option.
If we do, the ROARS will bear interest at a floating rate equal to the Floating
Period Interest Rate until the earlier of June 15, 2004, or such date which
otherwise would be the Reference Rate Reset Date immediately following the date
on which we elect to terminate such Floating Rate Period (the "Floating Rate
Period Termination Notification Date," such Floating Rate Period Termination
Notification Date to be at least four Business Days prior to such Reference Rate
Reset Date). The last day of such period, which shall not be later than
June 15, 2004, is called the "Floating Period Termination Date". In the event
that we exercise our Floating Period Option, the maturity date of the ROARS may
be adjusted to a date which shall be no later than the tenth anniversary of the
Fixed Rate Remarketing Date, which shall not be later than June 15, 2014.

    The amount of interest payable for each day that the ROARS are outstanding
during the Floating Rate Period will be calculated by dividing the Floating
Period Interest Rate in effect for such day by 360 and multiplying the result by
the Dollar Price. The amount of interest payable for any Floating Rate Reset
Period (as defined below) will be calculated by adding the interest payable for
each day in the Floating Rate Reset Period.

                                      S-15

    For this purpose, the following terms have the following meanings:

    "Floating Period Interest Rate" means the sum of the Reference Rate and the
Floating Rate Spread.

    "Floating Period Option" means our right, on any date subsequent to the
Remarketing Dealer's election to purchase the ROARS in connection with the first
Remarketing Date but prior to the fourth Business Day immediately preceding the
first Remarketing Date, to require the Remarketing Dealer to remarket the ROARS
at the Floating Period Interest Rate.

    "Floating Rate Period" means the period from and including the Floating Rate
Remarketing Date to but excluding the Floating Period Termination Date.

    "Floating Rate Remarketing Date" means June 15, 2003 in the event that we
have elected to exercise our Floating Period Option.

    "Floating Rate Reset Period" means the period from and including the first
Reference Rate Reset Date to but excluding the next following Reference Rate
Reset Date, and thereafter, the period from and including a Reference Rate Reset
Date to but excluding the next following Reference Rate Reset Date; PROVIDED
that the final Floating Rate Reset Period will run to but exclude the Floating
Period Termination Date.

    "Floating Rate Spread" means the lowest Floating Rate Bid expressed as a
spread (in the form of a percentage or in basis points) above the Reference Rate
for the ROARS, obtained by the Remarketing Dealer by 3:30 p.m., New York City
time, on the Floating Rate Spread Determination Date, from the Floating Rate
Bids quoted to the Remarketing Dealer by up to five Reference Money Market
Dealers.

    A "Floating Rate Bid" means an irrevocable offer to purchase the aggregate
outstanding principal amount of the ROARS at the Dollar Price, but assuming:

    (1) a settlement date that is the Floating Rate Remarketing Date, without
accrued interest;

    (2) a maturity date equal to the Floating Period Termination Date;

    (3) a stated annual interest rate equal to the Reference Rate plus the
spread bid by the applicable Reference Money Market Dealer;

    (4) that the ROARS are callable by the Remarketing Dealer at the Dollar
Price on the Floating Period Termination Date; and

    (5) that we will redeem the ROARS at the Dollar Price on the Floating Period
Termination Date, if not purchased by the Remarketing Dealer.

to the Floating Rate Remarketing Date.

    "Reference Money Market Dealer" means each of up to five leading dealers of
publicly traded debt securities, including our debt securities, which we shall
select, who are also leading dealers in money market instruments. We will advise
the Remarketing Dealer of our selection of Reference Money Market Dealers no
later than five Business Days prior to the Floating Rate Remarketing Date. One
of the Reference Money Market Dealers we select will be Banc of America
Securities LLC, if Banc of America Securities LLC is then the Remarketing
Dealer.

    "Reference Rate" means:

    (1) The rate for each Floating Rate Reset Period which will be the rate for
deposits in U.S. dollars for a period of one month which appears on the Telerate
Page 3750 (or any successor page) as of 11:00 a.m., London time, on the
applicable Reference Rate Determination Date.

    (2) If no rate appears on Telerate Page 3750 on the Reference Rate
Determination Date, the Remarketing Dealer will request the principal London
offices of four major reference banks in the London Inter-Bank Market, to
provide the Remarketing Dealer, in the case of each such bank, with its offered
quotation for deposits in U.S. dollars for the period of one month, commencing
on the first day of the Floating Rate Reset Period, to prime banks in the London
Inter-Bank Market at approximately

                                      S-16

11:00 a.m., London time, on that Reference Rate Determination Date and in a
principal amount that is representative for a single transaction in U.S. dollars
in that market at that time. If at least two quotations are provided, then the
Reference Rate will be the average of those quotations. If fewer than two

Remarketing Dealer for loans in U.S. dollars to leading European banks, having a
one-month maturity and in a principal amount that is representative for a single
transaction in U.S. dollars in that market at that time. If the banks selected
by the Remarketing Dealer are not providing quotations in the manner described
in this paragraph, the rate for the Floating Rate Reset Period following the
Reference Rate Determination Date will be the rate in effect on that Reference
Rate Determination Date.

    "Reference Rate Determination Date" will be the second London Business Day
preceding each Reference Rate Reset Date.

    "Reference Rate Reset Date" means June 15, 2003 and the 15th day of each
month thereafter until, but excluding, the Floating Period Termination Date, or
if such date does not fall on a Business Day, then the next succeeding Business

MANDATORY TENDER

    On a Business Day not earlier than 20 Business Days prior to the first
Remarketing Date, and not later than 4:00 p.m., New York City time, on the 15th
Business Day prior to such Remarketing Date, the Remarketing Dealer will notify
us and the Trustee as to whether it elects to purchase the ROARS for remarketing
on such Remarketing Date (the "Notification Date").

    If the Remarketing Dealer elects to purchase the ROARS for remarketing on
the first Remarketing Date, and upon the subsequent Remarketing Date, such ROARS
will be subject to mandatory tender, and will be deemed tendered, to the
Remarketing Dealer for purchase and remarketing on such Remarketing Date, in
accordance with the terms and subject to the conditions described in this
prospectus supplement.

    The ROARS will be remarketed at a fixed rate of interest equal to the
Interest Rate to Maturity, unless we have elected to exercise our Floating
Period Option or have chosen to redeem or are required to redeem the ROARS on
the applicable Remarketing Date. If we elect to exercise our Floating Period
Option, the ROARS will bear interest at the Floating Period Interest Rate until
the Floating Period Termination Date, at which time the ROARS will be remarketed
at a fixed rate of interest equal to the Interest Rate to Maturity unless we
have chosen to redeem or are required to redeem the ROARS.

    The purchase price of such tendered ROARS will be equal to 100% of the
aggregate principal amount thereof on the first Remarketing Date, or the Dollar
Price on the subsequent Remarketing Date.

    If the Remarketing Dealer elects to purchase the ROARS for remarketing, then
on the first Remarketing Date the Remarketing Dealer will sell the aggregate
principal amount of the ROARS at the Dollar Price to the Reference Corporate
Dealer if we do not exercise our Floating Period Option, or to the Reference
Money Market Dealer if we do exercise our Floating Period Option, providing the
lowest Fixed or Floating Rate Bid, as applicable. If the lowest applicable Bid
is submitted by two or more of the applicable Reference Dealers, the Remarketing
Dealer will sell such ROARS to one or more of such Reference Dealers, as it will
determine in its sole discretion.

    At the subsequent Remarketing Date for the ROARS following the Remarketing
Dealer's purchase of the ROARS, the Remarketing Dealer will then sell the
aggregate principal amount of the ROARS at the Dollar Price to the Reference
Corporate Dealer providing the lowest Fixed Rate Bid. If the lowest Fixed Rate
Bid is submitted by two or more of the

                                      S-17

Reference Corporate Dealers, the Remarketing Dealer may sell the ROARS to one or
more of such Reference Corporate Dealers, as it will determine in its sole
discretion.

    If the Remarketing Dealer elects to purchase the ROARS, the obligation of
the Remarketing Dealer to purchase the ROARS on any Remarketing Date is subject
to certain conditions set forth in the Remarketing Agreement.

    If for any reason the Remarketing Dealer does not purchase the ROARS on any
Remarketing Date, we will be required to redeem the ROARS at a price equal to
100% of their aggregate principal amount, plus accrued and unpaid interest, if
any, if such Remarketing Date is the first Remarketing Date, or at the Dollar
Price, plus accrued and unpaid interest, if any, on the subsequent Remarketing
Date.

MANDATORY REDEMPTION

    We will be required to redeem the ROARS in whole on the applicable
Remarketing Date at a price equal to 100% of the aggregate principal amount of
the ROARS, if such Remarketing Date is the first Remarketing Date, or at the
Dollar Price on the subsequent Remarketing Date, plus in each case, accrued and
unpaid interest, if any, to the applicable Remarketing Date, in the event that:

    (1) the Remarketing Dealer for any reason does not elect, by notice to us
and the Trustee not later than the Notification Date to remarket the ROARS, to
purchase the ROARS for remarketing on such Remarketing Date;

    (2) prior to any Remarketing Date, the Remarketing Dealer resigns and no
successor has been appointed on or before the applicable Determination Date;

    (3) at any time after the Remarketing Dealer elects on the Notification Date
to remarket the ROARS, the Remarketing Dealer elects to terminate the
Remarketing Agreement in accordance with its terms;

    (4) the Remarketing Dealer for any reason does not notify us of the Floating
Rate Spread or of the Interest Rate to Maturity by 4:00 p.m., New York City
time, on the applicable Determination Date;

    (5) the Remarketing Dealer for any reason does not deliver the purchase
price of the ROARS to the Trustee in same day funds not later than 12:00 noon,
New York City time, on such Remarketing Date, or does not purchase all tendered
ROARS on such Remarketing Date; or

    (6) we for any reason fail to redeem the ROARS from the Remarketing Dealer
following our election to effect such optional redemption.

OPTIONAL REDEMPTION

    If the Remarketing Dealer elects to purchase the ROARS, we will notify the
Remarketing Dealer and the Trustee, not later than 4:00 p.m., New York City
time, on the Business Day immediately preceding any Determination Date, if we
irrevocably elect to exercise our right to redeem the ROARS in whole either on
the first Remarketing Date or on the Floating Period Termination Date
immediately following such Determination Date; provided however in the event
that fewer than three Reference Corporate Dealers submit timely, firm, committed
bids for all outstanding ROARS to the Remarketing Dealer on the relevant
Determination Date, we will give such notice immediately after the deadline set
by the Remarketing Dealer for receiving such bids has passed and we have been
notified of the results.

    If we exercise our right to redeem the ROARS, we will redeem the ROARS in
whole on the first Remarketing Date or the subsequent Remarketing Date at the
Dollar Price, in each case, plus all accrued and unpaid interest, if any, to
such Remarketing Date. No notice of such redemption will be provided to holders
of the ROARS. In any case, we will make payment to each beneficial owner of the
ROARS by book-entry through DTC. Other than as set forth above, we will have no
option to redeem the ROARS prior to the Fixed Rate Remarketing Date.

POST-REMARKETING OPTIONAL REDEMPTION

    After the Fixed Rate Remarketing Date, the ROARS are subject to redemption
upon not less

                                      S-18

than 30 nor more than 60 days' notice by mail, at any time, as whole or in part,
at our election, at a price equal to the sum of (i) 100% of the principal amount
thereof plus accrued and unpaid interest to the redemption date plus (ii) the
Make-Whole Amount, if any.

    The term "Make-Whole Amount" shall mean, in connection with any optional
redemption of any ROARS, the excess, if any, of (i) the aggregate present value
as of the date of such redemption of each dollar of principal being redeemed and
the amount of interest (exclusive of interest accrued to the redemption date)
that would have been payable in respect of such dollar if such prepayment had
not been made, determined by discounting, on a semiannual basis, such principal
and interest at the Reinvestment Rate (determined on the Business Day preceding
the date of such redemption) from the respective dates on which such principal
and interest would have been payable if such payment had not been made, over
(ii) the aggregate principal amount of the ROARS being redeemed.

    The term "Reinvestment Rate" shall mean 0.50% (one-half of one percent) plus
the arithmetic mean of the yields under the respective headings "This Week" and
"Last Week" published in the Statistical Release under the caption "Treasury
Constant Maturities" for the maturity (rounded to the nearest month)
corresponding to the maturity of the principal being prepaid. If no maturity
exactly corresponds to such maturity, yields for the two published maturities
most closely corresponding to such maturity shall be calculated pursuant to the
immediately preceding sentence and the Reinvestment Rate shall be interpolated
or extrapolated from such yields on a straight-line basis, rounding in each of
such relevant periods to the nearest month. For the purpose of calculating the
Reinvestment Rate, the most recent Statistical Release published prior to the
date of determination of the Make-Whole Amount shall be used.

    The term "Statistical Release" shall mean the statistical release designated
"H.15(519)" or any successor publication which is published weekly by the
Federal Reserve System and which establishes yields on actively traded U.S.
government securities adjusted to constant maturities or, if such statistical
release is not published at the time of any determination under the Indenture,
then such other reasonably comparable index which shall be designated by us.

SETTLEMENT

    In the event that the ROARS are purchased by the Remarketing Dealer, the
Remarketing Dealer will pay to the Trustee, in same day funds not later than
12:00 noon, New York City time, on the first Remarketing Date, an amount equal
to 100% of the aggregate principal amount of the ROARS or on the subsequent
Remarketing Date, an amount equal to the Dollar Price.

    On any such Remarketing Date, the Remarketing Dealer will cause the Trustee
to make payment of the purchase price for such tendered ROARS that have been
purchased for remarketing by the Remarketing Dealer to DTC for payment to the
DTC participant of each tendering beneficial owner of ROARS. This payment will
be made against delivery through DTC of such beneficial owner's ROARS by
book-entry through DTC by the close of business on such Remarketing Date.

    The purchase price of such tendered ROARS will be equal to 100% of the
aggregate principal amount thereof, on the first Remarketing Date and the Dollar
Price, on the subsequent Remarketing Date. We will make, or cause the Trustee to
make, payment of interest to DTC for payment to each beneficial owner of ROARS,
due on a Remarketing Date by book-entry through DTC, by the close of business on
such Remarketing Date.

    The transactions described above will be executed on the applicable
Remarketing Date through DTC in accordance with the procedures of DTC, and the
accounts of the respective participants will be debited and credited, and the
ROARS delivered by book-entry as necessary to effect the purchases and sales
thereof.

    Settlement for the ROARS will be made by the underwriters in immediately
available funds. All payments of principal and interest in respect

                                      S-19

of the ROARS in book-entry form will be made in immediately available funds. The
ROARS will trade in DTC's Same-Day Funds Settlement System until the maturity
date, Remarketing Date or the post-remarketing redemption date, as the case may
be, or until the ROARS are issued in definitive form. Secondary market trading
activity in the ROARS will be required by DTC to settle in immediately available
funds.

    The tender and settlement procedures described above, including the
provisions for payment to selling beneficial owners of tendered ROARS, or for
payment by the purchasers of ROARS, in a remarketing, may be modified to the
extent required by DTC or, if the book-entry system is no longer available for
the ROARS at the time of a remarketing, to the extent required to facilitate the
tendering and remarketing of ROARS in certificated form. In addition, the
Remarketing Dealer may modify the settlement procedures set forth above in order
to facilitate the settlement process.

    As long as DTC or its nominee holds a certificate representing the ROARS in
the book-entry system of DTC, no certificates for such ROARS will be delivered
to any beneficial owner. In addition, under the terms of the ROARS and the
Remarketing Agreement, we have agreed that (1) we will use our reasonable best
efforts to maintain the ROARS in book-entry form with DTC or any successor
thereto, and to appoint a successor depositary to the extent necessary to
maintain the ROARS in book-entry form and (2) we will waive any discretionary
right we otherwise have under the Indenture to cause the ROARS to be issued in
certificated form.

REMARKETING DEALER

    On or prior to the date of original issuance of the ROARS, we will enter
into a Remarketing Agreement with the Remarketing Dealer. The Remarketing Dealer
will not receive any fees or reimbursement of expenses from us in connection
with the remarketing, except under certain circumstances. The aggregate amount
paid to us for the purchase of the ROARS will include an amount paid by the
Remarketing Dealer for its right to remarket the ROARS.

    We will agree to indemnify the Remarketing Dealer against certain
liabilities, including liabilities under the Securities Act, arising out of or
in connection with its duties under the Remarketing Agreement.

    If the Remarketing Dealer elects to purchase the ROARS for remarketing, the
obligation of the Remarketing Dealer to purchase the ROARS will be subject to
certain conditions set forth in the Remarketing Agreement. In addition, upon the
occurrence of certain events after the Remarketing Dealer elects to purchase the
ROARS for remarketing, the Remarketing Dealer will have the right to terminate
the Remarketing Agreement or terminate its obligation to purchase the ROARS, or,
until 3:30 p.m., New York City time, on the Business Day immediately preceding
the applicable Remarketing Date, to redetermine the applicable interest rate.

    No beneficial owner of the ROARS will have any rights or claims under the
Remarketing Agreement or against us or the Remarketing Dealer, as a result of
the Remarketing Dealer not purchasing the ROARS.

    The Remarketing Agreement will provide that the Remarketing Dealer may
resign at any time as Remarketing Dealer, such resignation to be effective ten
Business Days after the delivery to us and the Trustee of notice of such
resignation. In such case, we have no obligation to appoint a successor
Remarketing Dealer. After it purchases the ROARS, the Remarketing Dealer may
exercise any vote or join in any action that any beneficial owner of ROARS may
be entitled to exercise, or take, as if it did not act in any capacity under the
Remarketing Agreement. The Remarketing Dealer, in its individual capacity,
either as principal or agent, may engage in or have an interest in any financial
or other transaction with us, as freely as if it did not act in any capacity
under the Remarketing Agreement.

    As long as the Remarketing Agreement is in effect, we will not acquire any
of the ROARS prior to any Remarketing Date, without the prior written consent of
the Remarketing Dealer.

                                      S-20

    On or after the first Remarketing Date or termination of the Remarketing
Agreement prior thereto, we may at any time purchase any ROARS at any price in
the open market or otherwise. The ROARS so purchased by us may, at our
discretion, be held, resold or surrendered to the Trustee for cancellation.

RECENT ACCOUNTING DEVELOPMENTS

    For purposes of financial accounting and reporting for publicly held
companies, the Securities and Exchange Commission may require prospective
investors to separately account for the Remarketing Dealer's option to purchase
and to remarket the ROARS on the first Remarketing Date. Persons considering
investing in the ROARS, who are required to file financial reports with the
Securities and Exchange Commission pursuant to the Securities Exchange Act of
1934, as amended, should consult their own accounting advisors concerning
potential reporting requirements.

CERTAIN COVENANTS OF AES

    RESTRICTIONS ON SECURED DEBT.  If AES shall incur, issue, assume or
guarantee any indebtedness for borrowed money represented by notes, bonds,
debentures or other similar evidences of indebtedness, secured by a mortgage,
pledge or other lien on any Principal Property (as defined below) or any capital
stock or indebtedness held directly by AES of any Subsidiary of AES, AES shall
secure the Senior Notes equally and ratably with (or prior to) such
indebtedness, so long as such indebtedness shall be so secured, unless after
giving effect thereto the aggregate amount of all such indebtedness so secured,
together with all Attributable Debt (as defined below) in respect of sale and
leaseback transactions involving Principal Properties, would not exceed 15% of
the Consolidated Net Assets (as defined below) of AES. This restriction will not
apply to, and there shall be excluded in computing secured indebtedness for the
purpose of such restriction, indebtedness secured by (a) property of any
Subsidiary of AES, (b) liens on property of, or on any shares of stock or debt
of, any corporation existing at the time such corporation becomes a Subsidiary,
(c) liens in favor of AES or any Subsidiary, (d) liens in favor of U.S. or
foreign governmental bodies to secure partial, progress, advance or other
payments, (e) liens on property, shares of stock or debt existing at the time of
acquisition thereof (including acquisition through merger or consolidation),
purchase money mortgages and construction cost mortgages existing at or incurred
within 180 days of the time of acquisition thereof, (f) liens existing on the
first date on which any Senior Notes issued under the Indenture are
authenticated by the Trustee, (g) liens under one or more credit facilities for
indebtedness in an aggregate principal amount not to exceed $900 million at any
time outstanding, (h) liens incurred in connection with pollution control,
industrial revenue or similar financings, and (i) any extension, renewal or
replacement of any debt secured by any liens referred to in the foregoing
clauses (a) through (h), inclusive. As of the date of this prospectus
supplement, AES does not own or lease any Principal Property.

    The term "Principal Property" means any building, structure or other
facility (together with the land on which it is erected and fixtures comprising
a part thereof) used primarily for manufacturing, processing, research,
warehousing or distribution, owned or leased by AES and having a net book value
in excess of 2% of Consolidated Net Assets, other than any such building,
structure or other facility or portion thereof which is a pollution control
facility financed by state or local governmental obligations or which the
principal executive officer, president and principal financial officer of AES
determine in good faith is not of material importance to the total business
conducted or assets owned by AES and its Subsidiaries as an entirety.

    The term "Consolidated Net Assets" means the aggregate amount of assets
(less reserves and other deductible items) after deducting current liabilities,
as shown on the consolidated balance sheet of AES and its Subsidiaries contained
in the latest annual report to the stockholders of AES and prepared in
accordance with generally accepted accounting principles.

    The term "Attributable Debt" means the present value (discounted at the rate
of 7.375%

                                      S-21

per year compounded monthly) of the obligations for rental payments required to
be paid during the remaining term of any lease of more than 12 months.

    "Subsidiary" means, with respect to any person, any corporation, association
or other business entity of which a majority of the capital stock or other
ownership interests having ordinary voting power to elect a majority of the
board of directors or other persons performing similar functions are at the time
directly or indirectly owned by such person.

    RESTRICTIONS ON SALES AND LEASEBACKS.  AES may not enter into any sale and
leaseback transaction involving any Principal Property, the acquisition or
completion of construction and commencement of full operation of which has
occurred more than 180 days prior thereto, unless (a) AES could incur a lien on
such property under the restrictions described above under "Restrictions on
Secured Debt" in an amount equal to the Attributable Debt with respect to the
sale and leaseback transaction without equally and ratably securing the ROARS or
(b) AES, within 180 days after the sale or transfer by AES, applies to the
retirement of its funded debt (defined as indebtedness for borrowed money having
a maturity of, or by its terms extendible or renewable for, a period of more
than 12 months after the date of determination of the amount thereof) an amount
equal to the greater of (i) the net proceeds of the sale of the Principal
Property sold and leased pursuant to such arrangement or (ii) the fair market
value of the Principal Property so sold and leased (subject to credits for
certain voluntary retirements of funded debt) as determined by the Board of
Directors of AES.

EVENTS OF DEFAULT

    In addition to the Events of Default set forth in the accompanying
Prospectus, an Event of Default will occur with respect to the ROARS if an event
of default, as defined in any indenture or instrument evidencing or under which
AES has at the date of the Indenture or shall thereafter have outstanding any
indebtedness, shall happen and be continuing and either (a) such default results
from the failure to pay the principal of such indebtedness in excess of
$50 million at final maturity of such indebtedness or (b) as a result of such
default the maturity of such indebtedness shall have been accelerated so that
the same shall be or become due and payable prior to the date on which the same
would otherwise have become due and payable, and such acceleration shall not be
rescinded or annulled within 60 days and the principal amount of such
indebtedness, together with the principal amount of any other indebtedness of
AES in default, or the maturity of which has been accelerated, aggregates
$50 million or more; provided that the Trustee shall not be charged with
knowledge of any such default unless written notice thereof shall have been
given to the Trustee by AES, by the holder or an agent of the holder of any such
indebtedness, by the trustee then acting under any indenture or other instrument
under which such default shall have occurred, or by the holders of not less than
25% in the aggregate principal amount of the ROARS at the time outstanding; and
provided further that if such default shall be remedied or cured by AES or
waived by the holder of such indebtedness, then the Event of Default under the
Indenture by reason thereof shall be deemed likewise to have been remedied,
cured or waived without further action on the part of the Trustee, any holder of
ROARS or any other person.

RANKING

    The ROARS will be our direct, unsecured and unsubordinated obligations. The
ROARS will rank equal in priority with all of our existing and future unsecured
and unsubordinated indebtedness and senior in right of payment to all of our
existing and future subordinated debt. At March 31, 2001, we had outstanding
approximately $3,263,250,000 of unsecured and unsubordinated indebtedness and no
secured indebtedness. Our Indenture contains no restrictions on the amount of
additional indebtedness that we may issue under it.

FORM, DENOMINATION AND REGISTRATION

    The ROARS will be evidenced by one or more global securities (each, a
"Global

                                      S-22

ROARS"). The Global ROARS will be deposited with, or on behalf of, DTC or its
nominee. Except as set forth in the accompanying prospectus, the Global ROARS
may be transferred, in whole or in part, only to DTC, another nominee of DTC or
to a successor of DTC or its nominee. See "Settlement" and "Description of Debt
Securities--Book-Entry Systems" in the accompanying prospectus.

GOVERNING LAW

    The Indenture and the ROARS will be governed by and construed in accordance
with the laws of the State of New York, without giving effect to such state's
conflict of laws principles.

OTHER PROVISIONS

    See the accompanying prospectus for a description of certain additional
provisions of the Indenture, including Events of Default thereunder and
provisions for amendments and modifications thereof.

INFORMATION CONCERNING THE TRUSTEE

    AES and its subsidiaries may maintain deposit accounts and conduct other
banking transactions with the Trustee in the ordinary course of business.

                      CERTAIN UNITED STATES FEDERAL INCOME
                               TAX CONSIDERATIONS

    The following summary of certain United States federal income tax
consequences of the purchase, ownership and disposition of the Senior Notes and
the ROARS (together, the "Notes") is based upon the Internal Revenue Code of
1986, as amended (the "Code"), Treasury regulations, Internal Revenue Service
("IRS") rulings and pronouncements and administrative and judicial decisions
currently in effect, all of which are subject to change (possibly with
retroactive effect) or possible differing interpretations. This summary deals
only with Senior Notes and ROARS that are (i) purchased by initial Holders at
the public offering prices as set forth on the cover page hereof (which amounts
are assumed for purposes of this discussion to be the "issue price" for United
States federal income tax purposes of the Senior Notes and the ROARS,
respectively); and (ii) held as "capital assets" (as defined in the Code). It
does not purport to deal with persons in special tax situations, such as
financial institutions, regulated investment companies, real estate investment
trusts, dealers in securities or currencies, persons holding Notes as a hedge
against currency risk or as a position in a "straddle" or conversion
transaction, or persons whose functional currency is not the U.S. dollar. This
discussion does not address the tax consequences to partnerships or other pass-
through entities or persons investing through such partnerships or entities.

    PROSPECTIVE INVESTORS CONSIDERING THE PURCHASE OF THE NOTES SHOULD CONSULT
THEIR OWN TAX ADVISORS CONCERNING THE APPLICATION OF UNITED STATES FEDERAL
INCOME TAX LAWS TO THEIR PARTICULAR SITUATIONS AS WELL AS ANY CONSEQUENCES OF
THE PURCHASE, OWNERSHIP AND DISPOSITION OF THE NOTES ARISING UNDER THE LAWS OF
ANY OTHER TAXING JURISDICTION.

    As used herein, the term "U.S. Holder" means a beneficial owner of a Note
that, for United States federal income tax purposes, is (i) a citizen or
resident of the United States; (2) a corporation (or other entity treated as a
corporation for federal income tax purposes) created or organized in or under
the laws of the United States, or of any political subdivision thereof; or
(3) an estate or trust the income of which is subject to United States federal
income tax regardless of its source. The term "non-U.S. Holder" means a
beneficial owner of a Note that is not a U.S. Holder.

EXPECTED TAX CHARACTERIZATION OF THE ROARS

    Although there are no cases or rulings with respect to instruments with
terms similar to those of the ROARS, and the matter is not free from doubt,
Shearman & Sterling, special tax counsel to AES, has advised us that the ROARS
should be treated as fixed rate debt instruments that mature on the first
Remarketing Date. By purchasing the ROARS and pursuant to the indenture, a
Holder agrees (in the absence of an administrative determination or judicial
ruling to the contrary) to follow such treatment for United States federal
income tax purposes. No ruling on any of the issues relating to the ROARS will
be sought from the IRS. The IRS could assert a different characterization,
including the alternative characterization set forth below. Unless otherwise
stated, the remainder of this summary assumes that this treatment will be
respected.

TAX TREATMENT OF U.S. HOLDERS

    Interest on the Notes will constitute "qualified stated interest" and
generally will be taxable to a U.S. Holder as ordinary interest income at the
time such payments are accrued or received, in accordance with the U.S. Holder's
regular method of tax accounting.

    Upon the sale, exchange or retirement of a Note, a U.S. Holder generally
will recognize taxable gain or loss equal to the difference between the amount
realized on the sale, exchange or retirement (other than amounts

                                      S-24

representing accrued and unpaid interest, which will be treated as such) and
such U.S. Holder's adjusted tax basis in the Note. A U.S. Holder's adjusted tax
basis in a Note generally will equal the U.S. Holder's initial investment in the
Note. Except as provided below, such gain or loss generally will be capital gain
or loss, and will be long-term capital gain or loss if the Note is held by the
U.S. Holder for more than one year on the date of disposition.

POSSIBLE ALTERNATIVE TAX TREATMENT OF U.S. HOLDERS OF THE ROARS

    As noted above, there can be no assurance that the IRS will agree with our
treatment of the ROARS, and it is possible that the IRS could assert another
treatment. For instance, it is possible that the IRS could seek to treat the
ROARS as maturing on their stated maturity date and as having contingent
interest taxed under Treasury regulations governing debt instruments that
provide for contingent payments. Under these regulations, the amount treated as
taxable interest to Holders in each accounting period would be a hypothetical
amount based upon our current borrowing costs for comparable, noncontingent debt
instruments and a U.S. Holder might be required to include interest in income in
excess of actual cash payments received for certain taxable years. In addition,
if the ROARS were treated as contingent payment obligations, any gain upon their
sale or exchange (including a sale pursuant to the mandatory tender on the first
Remarketing Date) would be treated as ordinary income, any loss would be
ordinary to the extent of the U.S. Holder's prior ordinary income inclusions
with respect to the ROARS, and the balance would be treated as capital loss. It
is also possible that the IRS may treat U.S. Holders of ROARS as having issued
call options to the Remarketing Dealer in exchange for specified consideration
(in which case the issue price of the ROARS would be increased by an equal
amount), and U.S. Holders may be required to determine gain or loss with respect
to the ROARS and the call options separately. Such treatment could affect the
timing and character of recognition of income or loss in respect of the ROARS
and the call options.

TAX TREATMENT OF NON-U.S. HOLDERS

    A non-U.S. Holder generally will not be subject to United States federal
income or withholding taxes on payments of principal or interest on a Note,
unless such non-U.S. Holder (i) actually or constructively owns 10% or more of
the total combined voting power of all classes of our stock entitled to vote;
(ii) is a controlled foreign corporation related to us through stock ownership;
or (iii) is a bank receiving certain types of interest. To qualify for exemption
from withholding, a non-U.S. Holder must provide a statement (generally on IRS
Form W-8BEN), signed by the beneficial owner of the Note under penalties of
perjury, that certifies that the owner is not a U.S. person and provides the
name and address of the beneficial owner.

    Any gain or income realized by non-U.S. Holders upon the sale, exchange,
retirement or other disposition of a Note generally will not be subject to
United States federal income tax unless (i) the gain or income is effectively
connected with the conduct by the non-U.S. Holder of a trade or business in the
United States; or (ii) in the case of a non-U.S. Holder who is an individual,
the individual is present in the United States for 183 days or more in the
taxable year of the sale, exchange, retirement or other disposition, and certain
other conditions are met.

    A non-U.S. Holder that is engaged in a trade or business in the United
States will generally be taxed in the same manner as a U.S. Holder on payments
on, or gain from the sale, exchange, retirement or other disposition of, a Note
if such payments or gain are effectively connected with the conduct of such U.S.
trade or business. In addition, if such non-U.S. Holder is a foreign
corporation, it may be subject to a 30% branch profits tax (unless reduced or
eliminated by an applicable treaty) on its earnings and profits for the taxable
year attributable to such effectively connected income, subject to certain
adjustments.

INFORMATION REPORTING AND BACKUP WITHHOLDING

    Backup withholding at a rate of 31% may apply to payments made in respect of
a Note to

                                      S-25

registered owners who are not "exempt recipients" and who fail to provide
certain identifying information in the required manner. Generally, individuals
are not exempt recipients, but corporations and certain other entities are.
Payments made in respect of a Note to a U.S. Holder must be reported to the IRS,
unless the U.S. Holder is an exempt recipient or establishes an exemption.
Compliance with the identification procedures described in the preceding section
would establish an exemption from backup withholding for non-U.S. Holders.

    Upon the sale of a Note to or through a U.S. office of a broker, the broker
must withhold 31% of the entire purchase price, unless either (i) the broker
determines that the seller is a corporation or other exempt recipient; or
(ii) the seller provides, in the required manner, certain identifying
information and, in the case of a non-U.S. Holder, certifies that such seller is
a non-U.S. Holder and certain other conditions are met. Such a sale must also be
reported by the broker to the IRS unless either (i) the broker determines that
the seller is an exempt recipient; or (ii) the seller certifies its non-U.S.
status and certain other conditions are met. Certification of the registered
owner's non-U.S. status normally would be made on an IRS form (generally
Form W-8BEN) under penalties of perjury.

    Any amounts withheld under the backup withholding rules from a payment to a
beneficial owner would be allowed as a refund or a credit against the beneficial
owner's United States federal income tax, provided that the required information
is furnished to the IRS.

                                  UNDERWRITING

    Subject to the terms and conditions stated in the underwriting agreement
dated May 31, 2001, among us and the underwriters named below, we have agreed to
sell to each of the underwriters, and each of the underwriters has severally
agreed to purchase, the principal amount of Senior Notes and ROARS set forth
opposite its name.

                                                              ============   ============


    The underwriting agreement provides that the several obligations of the
underwriters to purchase the Senior Notes and the ROARS included in this
offering are subject to approval of a number of legal matters by counsel and to
some other conditions. The underwriters are obligated to purchase all of the the
Senior Notes or the ROARS, as applicable, if they purchase any of the Senior
Notes or the ROARS, as applicable.

    The underwriters propose to offer the Senior Notes and the ROARS to the
public at the respective public offering prices set forth on the cover page of
this prospectus supplement and to certain dealers at such prices less a
concession not in excess of 0.85% of the principal amount of the Senior Notes
and 0.45% of the principal amount of the ROARS. The underwriters may allow, and
such dealers may reallow, a discount not in excess of 0.70% of the principal
amount of the Senior Notes and 0.40% of the principal amount of the ROARS on
sales to certain other dealers. After the initial offering of the Senior Notes
and the ROARS to the public, the public offering prices and such concessions may
be changed by the underwriters.

    We have agreed that, without the prior written consent of Banc of America
Securities LLC acting on behalf of the other underwriters, we will not offer,
sell or otherwise dispose of any debt securities in the United States issued or
guaranteed by us (other than the Senior Notes and the ROARS), or publicly
announce an intention to effect any such transaction, prior to the closing of
this offering.

    The Senior Notes and the ROARS are new issues of securities with no
established trading market. We do not intend to apply for listing of the Senior
Notes or the ROARS on any securities exchange or for quotation through any
inter-dealer quotation system. We have been advised by the underwriters that
they intend to make a market in the Senior Notes and the ROARS as permitted by
applicable laws and regulations. The underwriters are not obligated, however, to
make a market in the Senior Notes or the ROARS, and any market making may be
discontinued at any time without notice. No assurances can be given as to the
liquidity of, or trading market for, the Senior Notes or the ROARS.

    In connection with the offering, certain underwriters and their affiliates
may purchase and sell the Senior Notes and the ROARS in the open market. These
transactions may include over-allotment, syndicate covering transactions and
stabilizing transactions. Over-allotment involves syndicate sales of the Senior
Notes or the ROARS in excess of the principal amount of the Senior Notes or the
ROARS to be purchased by the underwriters in the offering, which creates a
syndicate short position. Syndicate covering transactions involves purchases of
the Senior Notes or the ROARS in the open market after the distribution has been
completed in order to cover syndicate short positions. Stabilizing transactions
consist of certain bids or purchases of the Senior Notes or the ROARS made for
the purpose of preventing or retarding a decline in the market price of the

                                      S-27

Senior Notes or the ROARS, as applicable, while the offering is in progress.

    The underwriters may also impose a penalty bid. Penalty bids permit the
underwriters to reclaim a selling concession from a syndicate member when they,
in covering syndicate short positions or making stabilizing purchases,
repurchase the Senior Notes or the ROARS originally sold by that syndicate
member.

    Any of these activities may cause the price of the Senior Notes or the ROARS
to be higher than the price that otherwise would exist in the open market in the
absence of such transactions. These transactions may be effected in the
over-the-counter market or otherwise and, if commenced, may be discontinued at
any time.

    We estimate that our total expenses of this offering will be $200,000.

    The Remarketing Dealer will pay to us 2.640% of the aggregate principal
amount of the ROARS as consideration for the right to repurchase the ROARS at
100% of their aggregate principal amount on the first Remarketing Date.

    If the Remarketing Dealer purchases the ROARS on the first Remarketing Date
and subsequently offers the ROARS for resale, the resale of the ROARS may have
to be registered with the Securities and Exchange Commission under the
Securities Act, if an exemption from registration is not available. If the
resale of the ROARS has to be registered, we have agreed to pay the expenses
incident to such a registration.

    The underwriters and their respective affiliates may have performed certain
investment banking or commercial banking transactions on our behalf from time to
time for which they have received customary fees and expenses. The underwriters
and their respective affiliates may, from time to time, engage in transactions
with and perform services on our behalf in the ordinary course of their
business.

    Affiliates of the underwriters are lenders under our revolving credit
agreement, a portion of which is expected to be temporarily repaid out of a
portion of the proceeds of this offering.

    AES has agreed to indemnify the underwriters against certain liabilities,
including liabilities under the Securities Act of 1933, or to contribute to
payments the underwriters may be required to make in respect of any of those
liabilities.

                                 LEGAL MATTERS

The validity of the Senior Notes and the ROARS offered hereby and certain
matters relating thereto will be passed upon for us by Davis Polk & Wardwell,
New York, New York, and by Shearman & Sterling, special tax counsel to AES.

                                  RISK FACTORS

    PURCHASERS OF THE SECURITIES SHOULD READ THIS ENTIRE PROSPECTUS CAREFULLY.
OWNERSHIP OF THE SECURITIES INVOLVES CERTAIN RISKS. THE FOLLOWING FACTORS SHOULD
BE CONSIDERED CAREFULLY IN EVALUATING AES AND ITS BUSINESS BEFORE PURCHASING THE
SECURITIES OFFERED BY THIS PROSPECTUS.

    OUR HIGH DEGREE OF LEVERAGE COULD AFFECT OUR ABILITY TO FULFILL OUR
OBLIGATIONS UNDER OUR SECURITIES. We had approximately $13,715 million of
outstanding indebtedness at March 31, 2000. As a result, we might be
significantly limited in our ability to meet our debt service obligations, to
finance the acquisition, development or completion of additional projects, to
compete effectively or to operate successfully under adverse economic
conditions. As of March 31, 2000, we had a consolidated ratio of total debt to
total book capitalization (including current debt) of approximately 72%.

    HOLDERS OF OUR DEBT SECURITIES WILL BE SUBORDINATED TO MANY OF OUR OTHER
CREDITORS.  The Senior Subordinated Debt Securities will be subordinated to all
Senior Debt, including, but not limited to, the amounts outstanding under our
current $850 million revolving credit facility. The Junior Subordinated Debt
Securities will be subordinated to all of our Senior and Senior Subordinated
Debt, including, but not limited to, the amounts outstanding under our current
$850 million revolving credit facility. As of March 31, 2000, we had
approximately $1,581 million in aggregate principal amount of Senior Debt (which
includes $346 million of letters of credit) and $2,656 million in aggregate
principal amount of Senior and Senior Subordinated Debt.

    Upon any payment or distribution of assets to creditors upon any
liquidation, dissolution, winding up, receivership, reorganization, assignment
for the benefit of creditors, marshaling of assets and liabilities or any
bankruptcy, insolvency or similar proceedings, the holders of Senior Debt will
be entitled to receive payment in full of all amounts due under all Senior Debt
before the holders of the Senior Subordinated Debt Securities will be entitled
to receive any payment in respect of the Senior Subordinated Debt Securities;
holders of Senior and Senior Subordinated Debt will be entitled to receive
payment in full of all amounts due under all Senior and Senior Subordinated Debt
before the holders of the Junior Subordinated Debt Securities will be entitled
to receive any payment in respect of the Junior Subordinated Debt Securities.

    No payments in respect of the Senior Subordinated Debt Securities or Junior
Subordinated Debt Securities may be made

    - if a default has occurred and is continuing in a payment under the Senior
      Debt or Senior and Senior Subordinated Debt, respectively, or

    - during certain periods when an event of default under certain Senior Debt
      or Senior and Senior Subordinated Debt, respectively, permits the
      respective lenders thereunder to accelerate the maturity thereof.

    See "Description of Debt Securities--Subordination of Senior Subordinated
Debt Securities" and "Description of Debt Securities--Subordination of Junior
Subordinated Debt Securities."

    The Debt Securities will be effectively subordinated to the indebtedness and
other obligations (including trade payables) of our subsidiaries. At March 31,
2000, the indebtedness and obligations of our subsidiaries aggregated
approximately $13,335 million. Our ability to pay principal of, premium, if any,
and interest on the Debt Securities will be dependent upon the receipt of funds
from our subsidiaries by way of dividends, fees, interest, loans or otherwise.
Most of our subsidiaries with interests in power generation facilities currently
are obligated, pursuant to loan agreements or indentures, to satisfy certain
restricted payment covenants before they may make distributions to us. Moreover,
unless otherwise provided in the prospectus supplement, the Indentures for the
Debt Securities will permit our subsidiaries to maintain or add to such
restrictions. Our subsidiaries are separate and distinct legal

                                       3

entities and have no obligation, contingent or otherwise, to pay any amounts due
pursuant to the Debt Securities or to make any funds available therefor, whether
by dividends, loans or other payments, and do not guarantee the payment of
interest on or principal of the Debt Securities. Any right we have to receive
any assets of any of our subsidiaries upon any liquidation, dissolution, winding
up, receivership, reorganization, assignment for the benefit of creditors,
marshaling of assets and liabilities or any bankruptcy, insolvency or similar
proceedings (and the consequent right of the holders of the Debt Securities to
participate in the distribution of, or to realize proceeds from, those assets)
will be effectively subordinated to the claims of any such subsidiary's
creditors (including trade creditors and holders of debt issued by such
subsidiary).

    WE DO A SIGNIFICANT AMOUNT OF OUR BUSINESS OUTSIDE THE UNITED STATES WHICH
PRESENTS SIGNIFICANT RISKS.  Our involvement in the development of new
businesses and the acquisition of existing plants in locations outside the
United States is increasing and a large portion of our current development and
acquisition activities are for projects and plants outside the United States.

    The financing, development and operation of projects outside the United
States entail significant political and financial uncertainties (including,
without limitation, uncertainties associated with first-time privatization
efforts in the countries involved, currency exchange rate fluctuations, currency
repatriation restrictions, regulation of the electricity business, currency
inconvertibility, tax law, political instability, civil unrest, and
expropriation) and other credit quality, liquidity or structuring issues that
have the potential to cause substantial delays in respect of or material
impairment of the value of the project being developed or operated, which we may
not be capable of fully insuring or hedging against. The ability to obtain
financing on a commercially acceptable non-recourse basis in developing nations
has become more difficult. Even when such non-recourse financing is available,
lenders may require us to make higher equity investments than historically have
been the case. In addition, financing in countries with less than investment
grade sovereign credit ratings may also require substantial participation by
multilateral financing agencies. There can be no assurance that such financing
can be obtained when needed.

    The uncertainty of the legal environment in certain countries in which we
are or in the future may be developing, constructing or operating could make it
more difficult for us to enforce our respective rights under agreements relating
to such businesses. In addition, the laws and regulations of certain countries
may limit our ability to hold a majority interest in some of the businesses that
we may develop or acquire. International businesses we own may, in certain
cases, be expropriated by applicable governments. Although we may have legal
recourse in enforcing our rights under agreements and recovering damages for
breaches thereof, there can be no assurance that any such legal proceedings will
be successful or resolved in a timely manner.

    GLOBAL COMPETITION IS INCREASING AND COULD ADVERSELY AFFECT US.  The global
power production market is characterized by numerous strong and capable
competitors, many of whom may have extensive and diversified developmental or
operating experience (including both domestic and international experience) and
financial resources similar to or greater than ours. Further, in recent years,
the power production industry has been characterized by strong and increasing
competition with respect to both obtaining power sales agreements and acquiring
existing power generation assets. In certain markets, these factors have caused
reductions in prices contained in new power sales agreements and, in many cases,
have caused higher acquisition prices for existing assets through competitive
bidding practices. The evolution of competitive electricity markets and the
development of highly efficient gas-fired power plants have also caused, or are
anticipated to cause, price pressure in certain power markets where we sell or
intend to sell power. There can be no assurance that the foregoing competitive
factors will not have a material adverse effect on us.

    DEVELOPMENT UNCERTAINTIES.  The majority of the projects that we develop are
large and

                                       4

complex and the completion of any such project is subject to substantial risks.
Development can require us to expend significant sums for preliminary
engineering, permitting, legal and other expenses in preparation for competitive
bids which we may not win or before it can be determined whether a project is
feasible, economically attractive or capable of being financed. Successful
development and construction is contingent upon, among other things, negotiation
of satisfactory engineering, construction, fuel supply and power sales contracts
with other project participants, receipt of required governmental permits and
consents and timely implementation and satisfactory completion of construction.
There can be no assurance that we will be able to obtain new power sales
contracts, overcome local opposition, if any, obtain the necessary site
agreements, fuel supply and ash disposal agreements, construction contracts,
steam sales contracts, licenses and certifications, environmental and other
permits and financing commitments necessary for the successful development of
our projects. There can be no assurance that development efforts on any
particular project, or our efforts generally, will be successful. If these
development efforts are not successful, we may abandon a project under
development. At the time of abandonment, we would expense all capitalized
development costs incurred in connection therewith and could incur additional
losses associated with any related contingent liabilities. Our future growth is
dependent, in part, upon the demand for significant amounts of additional
electrical generating capacity and our ability to obtain contracts to supply
portions of this capacity. Any material unremedied delay in, or unsatisfactory
completion of, construction of our projects could, under certain circumstances,
have an adverse effect on our ability to meet our obligations, including the
payment of principal of, premium, if any, and interest on Debt Securities. We
may also be faced with certain development uncertainties arising out of doing
business outside of the United States. See "--We do a significant amount of our
business outside the United States which presents significant risks."

    OUR ACQUISITIONS MAY NOT PERFORM AS EXPECTED. We have achieved a majority of
our growth through acquisitions and expect that we will continue to grow, in
part, through acquisitions. Although each of the acquired businesses had a
significant operating history at the time we acquired them, we have a limited
history of owning and operating many of these businesses. In addition, most of
these businesses were government owned and some were operated as part of a
larger integrated utility prior to their acquisition. There can be no assurances
that we will be successful in transitioning these to private ownership, that
such businesses will perform as expected or that the returns from such
businesses will support the indebtedness incurred to acquire them or the capital
expenditures needed to develop them.

    WE MAY NOT BE ABLE TO RAISE SUFFICIENT CAPITAL TO FUND ACQUISITIONS AND
GREENFIELD PROJECTS OR REFINANCE EXISTING DEBT.  Each of our projects under
development and those independent power facilities we have committed to acquire
or may seek to acquire may require substantial capital investment. Continued
access to capital with acceptable terms is necessary to assure the success of
future projects and acquisitions, and may be necessary to refinance certain
existing debt. We have utilized project financing loans to fund the capital
expenditures associated with constructing and acquiring our electric power
plants and related assets to the extent possible. Project financing borrowings
have been substantially non-recourse to our other subsidiaries and affiliates
and to us as the parent company and are generally secured by the capital stock,
physical assets, contracts and cash flow of the related project subsidiary or
affiliate. We intend to continue to seek, where possible, such non-recourse
project financing. However, depending on market conditions and the unique
characteristics of individual projects, such financing may not be available or
our traditional providers of project financing, particularly multinational
commercial banks, may seek higher borrowing spreads and increased equity
contributions.

                                       5

    Furthermore, because of the reluctance of commercial lending institutions to
provide non-recourse project financing (including financial guarantees) in
certain less developed economies, we have sought and will continue to seek, in
such locations, direct or indirect (through credit support or guarantees)
project financing from a limited number of multilateral or bilateral
international financial institutions or agencies. As a precondition to making
such project financing available, these institutions may also require
governmental guarantees of certain project and sovereign related risks.
Depending on the policies of specific governments, such guarantees may not be
offered and as a result, we may determine that sufficient financing will
ultimately not be available to fund the related project. In addition, we are
frequently required to provide more sponsor equity for projects that sell their
electricity into the merchant market than for projects that sell their
electricity under long term contracts.

    In addition to the project financing loans, if available, we provide a
portion, or in certain instances all, of the remaining long-term financing
required to fund development, construction, or acquisition. These investments
have generally taken the form of equity investments or loans, which are
subordinated to the project financing loans. The funds for these investments
have been provided by cash flows from operations and by the proceeds from
borrowings under our short-term credit facilities and issuances of senior notes,
senior subordinated notes, convertible debentures, convertible trust preferred
securities and common stock.

    Our ability to arrange for financing on either a fully recourse or a
substantially non-recourse basis and the costs of such capital are dependent on
numerous factors, including general economic and capital market conditions, the
availability of bank credit, rating agency ratings, investor confidence, the
continued success of current projects and provisions of tax and securities laws
which are conducive to raising capital in this manner. Should future access to
capital not be available, we may decide not to build new plants or acquire
existing facilities. While a decision not to build new plants or acquire
existing facilities would not affect the results of operations of our currently
operating facilities or facilities under construction, such a decision would
affect our future growth.

    THE PERFORMANCE OF OUR GENERATION BUSINESS IS DEPENDENT TO A LARGE DEGREE ON
CERTAIN OF OUR LARGER PROJECTS AND THEIR CUSTOMERS.  The nature of most of our
generation plants (based on revenues) is such that each facility generally
relies on one power sales contract with a single customer for the majority, if
not all, of its revenues over the life of the power sales contract. The
prolonged failure of any significant customer to fulfill its contractual
obligations could have a substantial negative impact on these revenues. We have
sought to reduce this risk in part by entering into power sales contracts with
utilities or other customers of strong credit quality and by locating our plants
in different geographic areas in order to mitigate the effects of regional
economic downturns.

    OUR REVENUES ARE BECOMING LESS PREDICTABLE. Our business primarily consists
of businesses with long-term contracts or retail concessions, and we expect the
contract-based portfolio to be an effective hedge against future energy and
electricity market price risks. However, an increasing proportion of our current
and expected future revenues are derived from businesses without significant
long-term revenue contracts. Our increasing reliance on non-contract businesses
could cause our results of operations to become more volatile.

    OUR DISTRIBUTION BUSINESSES ARE SUBJECT TO GREATER REGULATORY SCRUTINY THAN
OUR GENERATION BUSINESS.  Our distribution businesses face increased regulatory
and political scrutiny in the normal conduct of their operations. This scrutiny
may adversely impact our results of operations, to the extent that such scrutiny
or pressure prevents us from reducing losses as quickly as we planned or denies
us a rate increase called for by our concession agreements. In general, these
businesses have lower margins and are more dependent on regulation to ensure
expected annual rate increases for inflation and increased power costs, among
other things. There can be

                                       6

no assurance that these rate reviews will be granted, or occur in a timely
manner.

    WE ARE SUBJECT TO SIGNIFICANT GOVERNMENT REGULATION.  Our generation
business in the United States is subject to the provisions of various laws and
regulations, including the Public Utility Regulatory Policies Act of 1978, as
amended, commonly referred to as PURPA, and the Public Utility Holding Company
Act, as amended, commonly referred to as PUHCA. PURPA provides to qualifying
facilities, commonly referred to as QFs, certain exemptions from substantial
federal and state legislation, including regulation as public utilities. PUHCA
regulates public utility holding companies and their subsidiaries. It is
necessary for us to obtain approval under PUHCA in order to maintain majority
ownership in our domestic power plants that are QFs. Currently a material
portion of our domestic revenues are received from QFs. Moreover, all of our
domestic non-QF plants are Exempt Wholesale Generators, commonly referred to as
EWGs. An EWG is a facility that has been authorized by the U.S. Federal Energy
Regulatory Commission, commonly referred to as the FERC, to sell wholesale power
at market-based rates. We enjoy exemptions under PUHCA related to our foreign
utility acquisitions and holdings. We cannot ensure that we will be able to
maintain appropriate PUHCA exemptions for all of our businesses. If we decide to
acquire another U.S. utility or utility assets, we may be required to divest
either all or part of CILCORP or take other steps resulting in a loss of control
or as may be required by the Securities and Exchange Commission. We believe
that, upon the occurrence of an event that would threaten the QF status of one
of our domestic plants, we would be able to react in a manner that would avoid
the loss of QF status (such as by replacing the steam customer). In the event we
were unable to avoid the loss of such status for one of our plants, to avoid
public utility holding company status, we could apply to the FERC to obtain
status as an EWG, or could restructure the ownership of the project subsidiary.
EWGs, however, are subject to broader regulation by FERC and may be subject to
state public utility commissions regulation regarding non-rate matters. In
addition, any restructuring of a project subsidiary could result in, among other
things, a reduced financial interest in such subsidiary, which could result in a
gain or loss on the sale of the interest in such subsidiary, the removal of such
subsidiary from our consolidated income tax group or our consolidated financial
statements, or an increase or decrease in our results of operations.

    PENDING ELECTRIC UTILITY INDUSTRY RESTRUCTURING PROPOSALS COULD HAVE AN
ADVERSE EFFECT ON US. Several states have passed legislation that allows
electricity customers to choose their electricity supplier in a competitive
electricity market (so-called "retail access" or "customer choice" laws), and
all but two of the remaining states are considering such legislation. In
addition to state restructuring legislation, some members of Congress have
proposed new Federal legislation to encourage customer choice and recovery of
stranded assets. Several bills have been submitted to Congress on electricity
restructuring. In anticipation of restructuring legislation, many U.S. utilities
are seeking ways to lower their costs in order to become more competitive. These
include the costs that utilities are required to pay under QF contracts. Many
utilities are therefore seeking ways to lower these contract prices by
renegotiating the contracts, or in some cases by litigation. In 1999, we
renegotiated contracts for two of our QFs--Thames (a partial prepayment) and
Placerita (a complete buyout). The Thames transaction has been approved by the
Connecticut Department of Public Utilities Commission.

    The FERC and many state utility commissions are currently studying a number
of proposals to restructure the electric utility industry in the United States.
Such restructuring would permit utility customers to choose their utility
supplier in a competitive electric energy market. The FERC issued a final rule
in April 1996 which requires utilities to offer wholesale customers and
suppliers open access on utility transmission lines, on a comparable basis to
the utilities' own use of the lines. The final rule is subject to rehearing and
may become the subject of court litigation. Many utilities have already filed
"open access" tariffs.

                                       7

The utilities contend that they should recover from departing customers their
fixed costs that will be "stranded" by the ability of their wholesale customers
(and perhaps eventually, their retail customers) to choose new electric power
suppliers. The FERC final rule endorses the recovery of legitimate and
verifiable "stranded costs." These may include the costs utilities are required
to pay under many QF contracts which the utilities view as excessive when
compared with current market prices. Many utilities are therefore seeking ways
to lower these contract prices or rescind the contracts altogether, out of
concern that their shareholders will be required to bear all or part of such
"stranded" costs. Some utilities have engaged in litigation against QFs to
achieve these ends.

    In addition, future United States electric rates may be deregulated in a
restructured United States electric utility industry and increased competition
may result in lower rates and less profit margin for United States electricity
sellers. Falling electricity prices, the introduction of commodity markets for
electricity and uncertainty as to the future structure of the industry has
rendered the long-term power purchase contracts obsolete. As a result, in the
generation business we are increasingly dependent upon prices for electricity
determined in electricity spot markets. Such prices can be very volatile and the
effect on us of this volatility cannot be predicted.

    The United States Congress is considering proposed legislation which would
repeal PURPA entirely, or at least repeal the obligation of utilities to
purchase from QFs. There is strong support for grandfathering existing QF
contracts if such legislation is passed, and also support for requiring
utilities to conduct competitive bidding for new electric generation if the
PURPA purchase obligation is eliminated. Various bills have also proposed repeal
of PUHCA. Repeal of PUHCA would allow power generators and vertically integrated
utilities to acquire retail utilities in the United States that are
geographically widespread, as opposed to the current limitations of PUHCA which
require that retail electric systems be capable of physical interconnection. In
addition, registered holding companies would be free to acquire non-utility
businesses, which they may not do now, with certain limited exceptions. In the
event that PUHCA is repealed, competition would likely increase. Repeal of PURPA
and/or PUHCA may or may not be part of comprehensive legislation to restructure
the electric utility industry, allow retail competition, and deregulate most
electric rates. The effect of any such repeal cannot be predicted, although any
such repeal could have a material adverse effect on us.

    FROM TIME TO TIME WE ARE SUBJECT TO MATERIAL LITIGATION AND REGULATORY
PROCEEDINGS.  From time to time, we and our affiliates are parties to litigation
and regulatory proceedings. Investors should review the descriptions of such
matters contained in our Annual, Quarterly and Current Reports filed with the
Securities and Exchange Commission and incorporated by reference herein. There
can be no assurances that the outcome of such matters will not have a material
adverse effect on our consolidated financial position.

    OUR BUSINESS IS SUBJECT TO STRINGENT ENVIRONMENTAL REGULATIONS.  Our
activities are subject to stringent environmental regulation by federal, state,
local and foreign governmental authorities. These regulations generally involve
effluents into the water, emissions into the air, the use of water, wetlands
preservation, waste disposal, endangered species, and noise regulation, among
others. Congress and other foreign governmental authorities also may consider
proposals to restrict or tax certain emissions. These proposals, if adopted,
could impose additional costs on the operation of our power plants. There can be
no assurance that we would be able to recover all or any increased costs from
our customers or that our business, financial condition or results of operations
would not be materially and adversely affected by future changes in domestic or
foreign environmental laws and regulations. We have made and will continue to
make capital and other expenditures to comply with environmental laws and
regulations. There can be no assurance that such expenditures will not have a
material adverse effect on our financial condition or results of operations.

                                       8

    OUR DIRECTORS AND OFFICERS HAVE SIGNIFICANT OWNERSHIP INTERESTS IN US AND
CAN EXERT SIGNIFICANT INFLUENCE OR CONTROL OVER MATTERS REQUIRING STOCKHOLDER
APPROVAL.  As of February 4, 2000 our two founders, Roger W. Sant and Dennis W.
Bakke, and their immediate families together owned beneficially approximately
18.4% of our outstanding Common Stock. As a result of their ownership interests,
Messrs. Sant and Bakke may be able to significantly influence or exert control
over our affairs, including the election of our directors. As of February 4,
2000, all of our officers and directors and their immediate families together
owned beneficially approximately 24.9% of our outstanding Common Stock. To the
extent that they decide to vote together, these stockholders would be able to
significantly influence or control the election of our directors, our management
and policies and any action requiring stockholder approval, including
significant corporate transactions.

    OUR ADHERENCE TO OUR "SHARED PRINCIPLES" COULD HAVE AN ADVERSE IMPACT ON OUR
RESULTS OF OPERATIONS.  A core part of our corporate culture is a commitment to
"shared principles": to act with integrity, to be fair, to have fun and to be
socially responsible. We seek to adhere to these principles not as a means to
achieve economic success, but because adherence is a worthwhile goal in and of
itself. However, if we perceive a conflict between these principles and profits,
we will try to adhere to our principles--even though doing so might result in
diminished or foregone opportunities or financial benefits.

    SHARES ELIGIBLE FOR FUTURE SALE.  From time to time, our subsidiaries incur
indebtedness that is secured by a pledge of shares of our common stock held by
that subsidiary. The sale of a substantial number of such shares in the public
market upon any foreclosure or otherwise could have an adverse effect on the
market price of our common stock.

    RISK OF FRAUDULENT TRANSFER.  Various fraudulent conveyance laws have been
enacted for the protection of creditors and may be applied by a court on behalf
of any unpaid creditor or a representative of our creditors in a lawsuit to
subordinate or avoid Debt Securities in favor of our other existing or future
creditors. Under applicable provisions of the U.S. Bankruptcy code or comparable
provisions of state fraudulent transfer or conveyance laws, if we at the time of
issuance of Debt Securities,

    - incurred such indebtedness with intent to hinder, delay or defraud any of
      our present or future creditors or contemplated insolvency with a design
      to prefer one or more creditors to the exclusion in whole or in part of
      others or

    - received less than reasonably equivalent value or fair consideration for
      issuing Debt Securities and we:

      - were insolvent,

      - were rendered insolvent by reason of the issuance of the Debt
        Securities,

      - were engaged or about to engage in business or a transaction for which
        our remaining assets constitute unreasonably small capital to carry on
        our business, or

      - intended to incur, or believed that we would incur, debts beyond our
        ability to pay such debts as they mature,

    then, in each case, a court of competent jurisdiction could void, in whole
or in part, the Debt Securities.

    Among other things, a legal challenge of the Debt Securities on fraudulent
conveyance grounds may focus on the benefits, if any, realized by us as a result
of our issuance of the Debt Securities.

    The measure of insolvency for purposes of the foregoing will vary depending
upon the law applied in such case. Generally, however, we would be considered
insolvent if the sum of our debts, including contingent liabilities, were
greater than all of our assets at fair valuation or if the present fair market
value of our assets were less than the amount that would be required to pay the
probable liability on our existing debts, including contingent liabilities, as
they become absolute and mature. There can be no assurance that, after providing
for all prior

                                       9

claims, there will be sufficient assets to satisfy the claims of the holders of
the Debt Securities.

    Management believes that, for purposes of all such insolvency, bankruptcy
and fraudulent transfer or conveyance laws, the Debt Securities are being
incurred without the intent to hinder, delay or defraud creditors and for proper
purposes and in good faith, and that we, after the issuance of the Debt
Securities, will be solvent, will have sufficient capital for carrying on our
business and will be able to pay our debts as they mature. There can be no
assurance, however, that a court passing on such questions would agree with
management's view.

    THERE IS NO PRIOR PUBLIC MARKET FOR MANY OF THE SECURITIES THAT MAY BE
OFFERED PURSUANT TO THIS PROSPECTUS--AS A RESULT THERE COULD BE SIGNIFICANT
PRICE VOLATILITY FOR SUCH SECURITIES.  Prior to the offering, there has been no
public market for many of the securities that may be offered pursuant to this
prospectus. There can be no assurance that an active trading market for any of
such securities will develop or be sustained. If such a market were to develop,
such securities could trade at prices that may be higher or lower than their
initial offering price depending upon many factors, including prevailing
interest rates, our operating results and the markets for similar securities.

                       RATIO OF EARNINGS TO FIXED CHARGES

    Our ratio of earnings to fixed charges is as follows:



                                                                                                                 THREE MONTHS
                                                                                                                    ENDED
                                                                        YEAR ENDED DECEMBER 31,                   MARCH 31,
                                                          ----------------------------------------------------   ------------
                                                            1995       1996       1997       1998       1999         2000

Ratio of earnings to fixed charges......................    2.20       1.88       1.46       1.65       1.50         2.08


    For the purpose of computing the ratio of earnings to fixed charges,
earnings consist of income from continuing operations before income taxes and
minority interest, plus depreciation of previously capitalized interest, plus
fixed charges, less capitalized interest, less excess of earnings over dividends
of less-than-fifty-percent-owned companies, less minority interest in pre-tax
income of subsidiaries that have not incurred fixed charges, less preference
security dividend requirements of a consolidated subsidiary. Fixed charges
consist of interest (including capitalized interest) on all indebtedness,
amortization of debt discount and capitalized expenses, preference security
dividend requirements of a consolidated subsidiary, and that portion of rental
expense which we believe to be representative of an interest factor.

    During the period from January 1, 1995 until March 31, 2000, no shares of
preferred stock were issued or outstanding, and during that period we did not
pay any preferred stock dividends.

                                  THE COMPANY

    We are a global power company committed to serving the world's needs for
electricity in a socially responsible way. Our electricity "generation" business
consists of sales to wholesale customers (generally electric utilities, regional
electric companies or wholesale commodity markets known as "power pools") for
further resale to end-users. We also sell electricity directly to end-users such
as commercial, industrial, governmental and residential customers through our
"distribution" business.

    Sales within our generation business are made under long-term contracts from
power plants owned by our subsidiaries and affiliates, as well as directly into
power pools. We own new plants constructed for such purposes ("greenfield"
plants) as well as older power plants acquired through competitively bid
privatization initiatives or negotiated acquisitions.

    Electricity sales by our distribution businesses, including affiliates, are
generally made pursuant of the provisions of long-term electricity sale
concessions granted by the appropriate governmental authorities. In certain
cases, these distribution companies are "integrated", in that they also own
electric power plants for the purpose of generating a portion of the electricity
they sell.

                          DESCRIPTION OF CAPITAL STOCK

    Under our certificate of incorporation (the "Certificate of Incorporation"),
we are authorized to issue 1,200,000,000 shares of common stock, par value $.01
per share, and 50,000,000 shares of preferred stock, no par value.

                                       12

    The following summary contains a description of certain general terms of the
common stock and the preferred stock to which any prospectus supplement may
relate. Certain terms of any series of preferred stock offered by a prospectus
supplement will be described in the prospectus supplement relating thereto. If
indicated in the prospectus supplement, the terms of any series may differ from
the terms set forth below. The description of certain provisions of the common
stock and the preferred stock is subject to and qualified by reference to the
provisions of our certificate of incorporation, and, in the case of the
preferred stock, to the certificate of designation (the "Certificate of
Designation") relating to each particular series of preferred stock which will
be filed or incorporated by reference as an exhibit to the registration
statement of which this prospectus is a part.

COMMON STOCK

    As of May 1, 2000, there were 207,770,572 shares of common stock
outstanding.

    The holders of common stock are entitled to one vote per share on all
matters to be voted upon by the stockholders. Subject to preferences that may be
applicable to any outstanding preferred stock, the holders of common stock are
entitled to receive ratably dividends as may be declared from time to time by
our board of directors out of funds legally available to pay dividends. If we
liquidate our business, the holders of common stock are entitled to share
ratably in all assets after we pay our liabilities and the liquidation
preference of any outstanding preferred stock. The common stock has no
preemptive or conversion rights or other subscription rights. There are no
redemption or sinking fund provisions applicable to the common stock. All
outstanding shares of common stock are fully paid and non-assessable, and any
shares of common stock in respect of which this prospectus is being delivered
will be fully paid and non-assessable.

    The transfer agent for our common stock is EquiServe.

PRICE RANGE OF AES COMMON STOCK AND COMMON STOCK DIVIDENDS

    Our common stock began trading on the New York Stock Exchange on
October 16, 1996 under the symbol "AES." The following table sets forth for the
periods indicated the intra-day high and low sale prices for the common stock as
reported on the Composite Tape. In April 2000, we announced a two-for-one stock
split, in the form of a stock dividend, for holders of record on May 1, 2000 of
our common stock, par value $.01 per share, which is payable on June 1, 2000.
The prices set forth below do not reflect adjustment for such stock split.

    No cash dividends have been paid on common stock since December 22, 1993 in
order to provide capital for our equity investments in projects.

    Our ability to declare and pay dividends is dependent, among other things,
on

    - the ability of our project subsidiaries to declare and pay dividends and
      otherwise distribute cash to us;

    - our ability to service our parent company debt and

    - our ability to meet certain criteria for paying dividends under our
      corporate

                                       13

      credit facility and under existing indentures of our debt securities.

    The ability of our subsidiaries to declare and pay dividends and otherwise
distribute cash to us is subject to certain limitations in the project loans and
other documents entered into by our project subsidiaries. These limitations
permit the payment of dividends out of current cash flow for quarterly,
semi-annual or annual periods only at the end of these periods and only after
payment of principal and interest on project loans due at the end of these
periods.

    Cash dividend payments on common stock are limited to a certain percentage
of cash flow under our corporate credit agreement. The indentures relating to
our existing senior subordinated notes preclude the payment of cash dividends
if:

    - at the time of a payment of cash dividends or after giving effect thereto
      an event of default occurred;

    - an event that would become an event of default occurred and is continuing;

    - certain fixed charge coverage ratios are not met or

    - if the payment of dividends, together with other restricted payments,
      would exceed certain limits.

PREFERRED STOCK

    As of May 1, 2000, there were no shares of Preferred Stock outstanding.

    Our board of directors has the authority to issue preferred stock in one or
more classes or series and to fix the rights, preferences, privileges and
restrictions thereof, including dividend rights, dividend rates, conversion
rights, exchange rights, voting rights, terms of redemption, redemption prices,
liquidation preferences and the number of shares constituting any class or
series or the designation of such class or series, without any further action by
the stockholders. Preferred stock, if issued, will not be entitled to any
preemptive or similar rights. The prospectus supplement will describe the terms
of any preferred stock being offered, including:

    - the specific designation, number of shares, seniority and purchase price;

    - any liquidation preference per share;

    - any date of maturity;

    - any redemption, repayment or sinking fund provisions;

    - any dividend rate or rates and the dates on which any such dividends will
      be payable (or the method by which such rates or dates will be
      determined);

    - any voting rights;

    - if other than the currency of the United States, the currency or
      currencies including composite currencies in which such preferred stock is
      denominated and/or in which payments will or may be payable;

    - the method by which amounts in respect of such preferred stock may be
      calculated and any commodities, currencies or indices, or value, rate or
      price, relevant to such calculation;

    - whether such preferred stock is convertible or exchangeable and, if so,
      the securities or rights into which such preferred stock is convertible or
      exchangeable, and the terms and conditions upon which such conversions or
      exchanges will be effected including conversion or exchange prices or
      rates, the conversion or exchange period and any other related provisions;

    - the place or places where dividends and other payments on the preferred
      stock will be payable; and

    - any additional voting, dividend, liquidation, redemption and other rights,
      preferences, privileges, limitations and restrictions.

    All shares of preferred stock offered hereby, or issuable upon conversion,
exchange or

                                       14

exercise of securities, will, when issued, be fully paid and non-assessable. Any
shares of preferred stock that are issued would have priority over the common
stock with respect to dividend or liquidation rights or both.

    The transfer agent for each series of preferred stock will be described in
the applicable prospectus supplement.

DESCRIPTION OF CERTAIN PROVISIONS OF OUR CERTIFICATE OF INCORPORATION AND
BY-LAWS

    Our Certificate of Incorporation and By-Laws contain several provisions that
may make the acquisition of control of the AES through a tender offer, open
market purchases, a proxy fight or otherwise more difficult. Below is a
description of certain of these provisions in the Certificate of Incorporation
and By-Laws.

    SPECIAL MEETINGS OF STOCKHOLDERS.  Our By-Laws provide that, unless
otherwise prescribed by law, special meetings of stockholders may be called by a
resolution adopted by a majority of the entire board of directors, by the
chairman of the board of directors or by the president. Only business as
specified in the notice of stockholders of the special meeting shall be
considered.

    STOCKHOLDER NOMINATION OF DIRECTORS.  Our By-Laws contain a procedure for
stockholder nomination of directors. The By-Laws provide that any record owner
of stock entitled to be voted generally in the election of directors may
nominate one or more persons for election as a director at a stockholders
meeting only if written notice is given to our secretary of the intent to make a
nomination. The notice must be given, with respect to an annual meeting, not
later than 90 days in advance of the annual meeting. With respect to a special
meeting, the notice must be given not later than the close of business on the
seventh day following the earlier of

    - the date on which notice of such special meeting is first given to
      stockholders and

    - the date on which a public announcement of such meeting is first made.

    Each notice must include:

    - the name and address of each stockholder who intends to appear in person
      or by proxy to make the nomination and of the person or persons to be
      nominated;

    - a description of all arrangements or understandings between the
      stockholder and each nominee and any other person or persons (naming them)
      pursuant to which the nomination is to be made by the stockholder;

    - other information regarding each nominee proposed as would have been
      included in a proxy statement filed pursuant to Rule 14a-8 under the
      Exchange Act and

    - the consent of each nominee to serve if elected.

    The presiding officer of the meeting may refuse to acknowledge the
nomination of any person not made in compliance with this procedure.

    The procedure for stockholder nomination of directors described above may
have the effect of precluding a nomination for election of directors at a
particular meeting if the required procedure is not followed.

    ELIMINATION OF LIABILITY; INDEMNIFICATION. Except as described below, the
Certificate of Incorporation eliminates the liability of members of our board of
directors to us or our stockholders for monetary damages resulting from breaches
of their fiduciary duties as directors. Directors remain liable for breaches of
their duty of loyalty to us or our stockholders, as well as for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law and transactions from which a director derives improper
personal benefit. The Certificate of Incorporation also does not release
directors of liability under Section 174 of the Delaware General Corporation Law
(the "GCL"), which makes directors personally liable for unlawful dividends or
unlawful stock repurchases or redemptions if

                                       15

the unlawful conduct is willful or results from negligence.

    Under our By-Laws, and in accordance with Section 145 of the GCL, we shall
indemnify to the fullest extent permitted by the GCL any person who was or is a
party or is threatened to be made a party to any threatened, pending or
completed action, suit or proceeding. These include civil, criminal,
administrative or investigative proceedings by reason of the fact that the
person is or was a director or officer of or employed by us, or is or was
serving in that capacity or as an agent at the request of us for another entity.
Our indemnification covers expenses, judgments, fines and amounts paid in
settlement actually and reasonably incurred in connection with the defense or
settlement of an action, suit or proceeding if the person acted in good faith
and in a manner the person reasonably believed to be in or not opposed to our
best interests and, with respect to any criminal action or proceeding, had no
reasonable cause to believe was unlawful. We will indemnify persons in a
derivative action under the same conditions, except that no indemnification is
permitted without judicial approval if the person is adjudged to be liable to us
in the performance of his or her duty. Derivative actions are actions by us or
in the right of us to procure a judgment in our favor. Agents of ours may be
similarly indemnified at the discretion of the board of directors.

    Under Section 145 of the GCL, a similar duty of care is applicable in the
case of derivative actions, except that indemnification only extends to expenses
incurred in connection with the defense or settlement of a derivative action and
then, where the person is adjudged to be liable to us, only if and to the extent
that the Court of Chancery of the State of Delaware or the court in which the
action was brought determines that the person is fairly and reasonably entitled
to the indemnity and only for those expenses as the court deems proper.

    Pursuant to our By-Laws, a person eligible for indemnification may have the
expenses incurred in connection with any matter described above paid in advance
of a final disposition by us. However, these advances will only be made if the
indemnified person undertakes to repay all advanced amounts if it is determined
that the person is not entitled to indemnification.

    In addition, under our By-Laws, we may purchase and maintain insurance on
behalf of any person who is or was a director, officer, employee or agent of us
or of another corporation against any liability arising out of the person's
status as director, officer, employee or agent of us whether or not we would
have the power to indemnify such person against such liability under the
provisions of our By-Laws. We maintain directors' and officers' insurance.

DEPOSITARY SHARES

    GENERAL.  We may, at our option, elect to offer fractional shares of
preferred stock, rather than full shares of preferred stock. If we exercise this
option, we will issue to the public receipts for depositary shares, and each of
these depositary shares will represent a fraction (to be set forth in the
application prospectus supplement) of a share of a particular series of
preferred stock.

    The shares of any series of preferred stock underlying the depositary shares
will be deposited under a deposit agreement between us and a bank or trust
company selected by us. The depositary will have its principal office in the
United States and a combined capital and surplus of at least $50,000,000.
Subject to the terms of the deposit agreement, each owner of a depositary share
will be entitled, in proportion, to the applicable fraction of a share of
preferred stock underlying that depositary share, to all the rights and
preferences of the preferred stock underlying that depositary share. Those
rights include dividend, voting, redemption and liquidation rights.

    The depositary shares will be evidenced by depositary receipts issued
pursuant to the deposit agreement. Depositary receipts will be distributed to
those persons purchasing the fractional shares of preferred stock underlying the
depositary shares, in accordance with the terms of the offering. Copies of the
forms of deposit agreement and depositary receipt will be filed as exhibits to
the registration statement.

                                       16

The following summary of the deposit agreement, the depositary shares and the
depositary receipts is not complete. You should refer to the forms of the
deposit agreement and depositary receipts that will be filed with the Securities
and Exchange Commission in connection with the offering of the specific
depositary shares.

    Pending the preparation of definitive engraved depositary receipts, the
depositary may, upon our written order, issue temporary depositary receipts
substantially identical to the definitive depositary receipts but not in
definitive form. These temporary depositary receipts entitle their holders to
all the rights of definitive depositary receipts which are to be prepared
without unreasonable delay. Temporary depositary receipts will then be
exchangeable for definitive depositary receipts at our expense.

    DIVIDENDS AND OTHER DISTRIBUTIONS.  The depositary will distribute all cash
dividends or other cash distributions received with respect to the preferred
stock to the record holders of depositary shares relating to the preferred stock
in proportion to the number of depositary shares owned by those holders.

    If there is a distribution other than in cash, the depositary will
distribute property received by it to the record holders of depositary shares
that are entitled to receive the distribution, unless the depositary determines
that it is not feasible to make the distribution. If this occurs, the depositary
may, with our approval, sell the property and distribute the net proceeds from
the sale to the applicable holders.

    REDEMPTION OF DEPOSITARY SHARES.  If a series of preferred stock represented
by depositary shares is subject to redemption, the depositary shares will be
redeemed from the proceeds received by the depositary resulting from the
redemption, in whole or in part, of that series of preferred stock held by the
depositary. The redemption price per depositary share will be equal to the
applicable redemption fraction of the redemption price per share payable with
respect to that series of the preferred stock. Whenever we redeem shares of
preferred stock that are held by the depositary, the depositary will redeem, as
of the same redemption date, the number of depositary shares representing the
shares of preferred stock so redeemed. If fewer than all the depositary shares
are to be redeemed, the depositary shares to be redeemed will be selected by lot
or pro rata as may be determined by the depositary.

    VOTING THE PREFERRED STOCK.  Upon receipt of notice of any meeting at which
the holders of the preferred stock are entitled to vote, the depositary will
mail the information contained in such notice to the record holders of the
depositary shares underlying the preferred stock. Each record holder of the
depositary shares on the record date (which will be the same date as the record
date for the preferred stock) will be entitled to instruct the depositary as to
the exercise of the voting rights pertaining to the amount of the preferred
stock represented by such holder's depositary shares. The depositary will then
try, as far as practicable, to vote the number of shares of preferred stock
underlying those depositary shares in accordance with such instructions, and we
will agree to take all actions which may be deemed necessary by the depositary
to enable the depositary to do so. The depositary will not vote the shares of
preferred stock to the extent it does not receive specific instructions from the
holders of depositary shares underlying the preferred stock.

    AMENDMENT AND TERMINATION OF THE DEPOSITARY AGREEMENT.  The form of
depositary receipt evidencing the depositary shares and any provision of the
deposit agreement may at any time be amended by agreement between us and the
depositary. However, any amendment which materially and adversely alters the
rights of the holders of depositary shares will not be effective unless the
amendment has been approved by the holders of at least a majority of the
depositary shares then outstanding. The deposit agreement may be terminated by
us or by the depositary only if (a) all outstanding depositary shares have been
redeemed or (b) there has been a final distribution of the underlying preferred
stock in connection with our liquidation, dissolution or winding up and the
preferred stock has been distributed to the holders of depositary receipts.

                                       17

    CHARGES OF DEPOSITARY.  We will pay all transfer and other taxes and
governmental charges arising solely from the existence of the depositary
arrangements. We will also pay charges of the depositary in connection with the
initial deposit of the preferred stock and any redemption of the preferred
stock. Holders of depositary receipts will pay other transfer and other taxes
and governmental charges and those other charges, including a fee for the
withdrawal of shares of preferred stock upon surrender of depositary receipts,
as are expressly provided in the deposit agreement to be for their accounts.

    MISCELLANEOUS.  The depositary will forward to holders of depositary
receipts all reports and communications from us that we deliver to the
depositary and that we are required to furnish to the holders of the preferred
stock.

    Neither we nor the depositary will be liable if either of us is prevented or
delayed by law or any circumstance beyond our control in performing our
respective obligations under the deposit agreement. Our obligations and those of
the depositary will be limited to performance in good faith of our respective
duties under the deposit agreement. Neither we nor the depositary will be
obligated to prosecute or defend any legal proceeding in respect of any
depositary shares or preferred stock unless satisfactory indemnity is furnished.
We and the depositary may rely upon written advice of counsel or accountants, or
upon information provided by persons presenting preferred stock for deposit,
holders of depositary receipts or other persons believed to be competent and on
documents believed to be genuine.

    RESIGNATION AND REMOVAL OF DEPOSITARY.  The depositary may resign at any
time by delivering notice to us of its election to resign. We may remove the
depositary at any time. Any resignation or removal will take effect upon the
appointment of a successor depositary and its acceptance of the appointment. The
successor depositary must be appointed within 60 days after delivery of the
notice of resignation or removal and must be a bank or trust company having its
principal office in the United States and having a combined capital and surplus
of at least $50,000,000.

                         DESCRIPTION OF DEBT SECURITIES

    The debt securities may consist of Senior Debt Securities, Subordinated Debt
Securities or Junior Subordinated Debt Securities. The Senior Debt Securities
will be issued under an indenture (the "Senior Debt Indenture") between AES, as
issuer, and either Bank One, National Association (formerly known as The First
National Bank of Chicago) or The Bank of New York, as trustee. The Senior
Subordinated Debt Securities will be issued under an indenture (the "Senior
Subordinated Debt Indenture") between AES, as issuer, and either Bank One,
National Association (formerly known as The First National Bank of Chicago) or
The Bank of New York, as trustee. The Junior Subordinated Debt Securities will
be issued under an indenture (the "Junior Subordinated Debt Indenture") between
AES, as issuer, and either Bank One, National Association (formerly known as The
First National Bank of Chicago) or The Bank of New York, as trustee. The Senior
Debt Indenture, the Senior Subordinated Debt Indenture and the Junior
Subordinated Debt Indenture are collectively referred to herein as the
"Indentures."

    The Indentures have been incorporated by reference or included herein as
exhibits to the registration statement of which this Prospectus is a part and
are also available for inspection at the office of the trustee. The Indentures
are subject to and governed by the Trust Indenture Act of 1939 (the "Trust
Indenture Act"). Section references contained herein are applicable to each of
the Indentures. The following summaries of the Indentures are not complete.
Where reference is made to particular provisions of the Indentures, these

relating to subordination.

                                       18

GENERAL

    None of the Indentures limits the amount of debt securities which may be
issued thereunder. Each Indenture provides that debt securities issuable
thereunder may be issued up to the aggregate principal amount which may be
authorized by us from time to time. The prospectus supplement will describe the
terms of any debt securities being offered (the "Offered Debt Securities")
including:

    - the designation, aggregate principal amount and authorized denominations
      of the Offered Debt Securities;

    - the date or dates on which the Offered Debt Securities mature;

    - the rate or rates per annum at which the Offered Debt Securities will bear
      interest and the method of calculating interest rates, if any;

    - the dates on which any interest will be payable and the record dates for
      any interest payments;

    - any mandatory or optional redemption terms or prepayment, conversion,
      sinking fund or exchangeability provisions;

    - the place where the principal of and interest on the Offered Debt
      Securities will be payable;

    - if other than denominations of $1,000 or multiples thereof, the
      denominations in which the Offered Debt Securities will be issuable;

    - whether the Offered Debt Securities will be issued in the form of Global
      Securities (as defined below) or certificates;

    - additional provisions, if any, relating to the defeasance of the Offered
      Debt Securities;

    - the currency or currencies, if other than the currency of the United
      States, in which payment of the principal of and interest on the Offered
      Debt Securities will be payable;

    - whether the Offered Debt Securities will be issuable in registered form or
      bearer form ("Bearer Securities") or both and, if Bearer Securities are
      issuable, any restrictions applicable to the exchange of one form for
      another and the offer, sale and delivery of Bearer Securities;

    - any applicable United States federal income tax consequences, including
      whether and under what circumstances we will pay additional amounts on
      Offered Debt Securities held by a person who is not a U.S. Person (as
      defined in each prospectus supplement relating to any particular series of
      debt securities offered thereby) in respect of any tax, assessment or
      governmental charge withheld or deducted and, if so, whether we will have
      the option to redeem these Offered Debt Securities rather than pay the
      additional amounts;

    - the dates on which premium, if any, will be payable;

    - our right, if any, to defer payment of interest and the maximum length of
      any deferral period;

    - any listing on a securities exchange;

    - the initial public offering price and

    - other specific terms, including any additional events of default or
      covenants provided for with respect to the Offered Debt Securities.

    As described in each prospectus supplement relating to any particular series
of debt securities offered thereby, the indenture may contain covenants
limiting:

    - the incurrence of debt by us;

    - the incurrence of debt by subsidiaries of us;

    - the making of certain payments by us and our subsidiaries;

    - subsidiary mergers;

    - business activities of us and our subsidiaries;

    - the issuance of preferred stock of subsidiaries;

                                       19

    - asset dispositions;

    - transactions with affiliates;

    - liens and

    - mergers and consolidations involving AES.

BOOK-ENTRY SYSTEMS

    If so specified in any prospectus supplement relating to debt securities,
debt securities of any series may be issued under a book-entry system in the
form of one or more global securities (each, a "Global Security"). Each Global
Security will be deposited with, or on behalf of, a depositary, which will be
The Depository Trust Company, New York, New York (the "Depositary"). The Global
Securities will be registered in the name of the Depositary or its nominee.

    The Depositary has advised us that the Depositary is a limited purpose trust
company organized under the laws of the State of New York, a "banking
organization" within the meaning of the New York banking law, a member of the
Federal Reserve System, a "clearing corporation" within the meaning of the New
York Uniform Commercial Code, and a "clearing agency" registered pursuant to the
provisions of Section 17A of the Exchange Act. The Depositary was created to
hold securities of its participants and to facilitate the clearance and
settlement of securities transactions among its participants through electronic
book-entry changes in accounts of the participants, thereby eliminating the need
for physical movement of securities certificates. The Depositary's participants
include securities brokers and dealers, banks, trust companies, clearing
corporations, and certain other organizations, some of which (and/or their
representatives) own the Depositary. Access to the Depositary's book-entry
system is also available to others, such as banks, brokers, dealers, and trust
companies that clear through or maintain a custodial relationship with a
participant, either directly or indirectly.

    When a Global Security is issued in registered form, the Depositary will
credit, on its book-entry registration and transfer system, the respective
principal amounts of the debt securities represented by each Global Security to
the participants' accounts. The accounts to be credited will be designated by
the underwriters, dealers, or agents, if any. If debt securities are offered and
sold directly by us, we will designate the accounts to be credited. Ownership of
beneficial interests in the Global Security will be limited to participants or
persons that may hold interests through participants. Ownership of beneficial
interests by participants in the Global Security will be shown on, and the
transfer of that ownership interest will be effected only through, the
participants' records. The laws of some jurisdictions may require that certain
purchasers of securities take physical delivery of the securities in definitive
form. These laws may impair the ability to transfer beneficial interests in a
Global Security.

    So long as the Depositary or its nominee is the owner of record of a Global
Security, we consider the Depositary or its nominee the sole owner or holder of
the debt securities represented by the Global Security for all purposes under
the Indenture under which the debt securities are issued. Except as set forth
below, owners of beneficial interests in a Global Security will not be entitled
to have the debt security represented by the Global Security registered in their
names, and will not receive or be entitled to receive physical delivery of the
Debt Securities in definitive form and will not be considered the owners or
holders thereof under the Indenture under which these debt securities are
issued. Accordingly, each person owning a beneficial interest in a Global
Security must rely on the procedures of the Depositary. Persons who are not
participants must rely on the procedures of the participant through which they
own their interest. We understand that under existing industry practices, if we
request any action of holders or if any owner of a beneficial interest in a
Global Security desires to give or take any action which a holder is entitled to
give or take under the applicable Indenture, the Depositary would authorize the
participants holding the relevant beneficial interests to give or take such
action, and such participants would authorize beneficial owners owning through
such participants to give or take such action or would

                                       20

otherwise act upon the instruction of beneficial owners holding through them.

    Payments of principal, premium, if any, and interest on debt securities
represented by a Global Security registered in the name of the Depositary or its
nominee will be made to the Depositary or nominee, as the registered owner. None
of AES, the trustee or any other agent of us or agent of the trustee will have
any responsibility or liability for any aspect of the records relating to or
payments made on account of beneficial ownership interests in the Global
Security or for maintaining, supervising, or reviewing any records relating to
such beneficial ownership interests.

    We have been advised by the Depositary that the Depositary will credit
participants' accounts with payments of principal, premium, if any, or interest
on the payment date thereof in amounts proportionate to their respective
beneficial interests in the principal amount of the Global Security as shown on
the records of the Depositary. We expect that payments by participants to owners
of beneficial interests in the Global Security held through such participants
will be governed by standing instructions and customary practices, as is now the
case with securities held for the accounts of customers registered in "street
name," and will be the responsibility of such participants.

    A Global Security may not be transferred except as a whole:

    - by the Depositary to a nominee or successor of the Depositary or

    - by a nominee of the Depositary to another nominee of the Depositary.

    A Global Security representing all but not part of an offering of debt
securities hereby is exchangeable for debt securities in definitive form of like
tenor and terms if:

    - The Depositary notifies us that it is unwilling or unable to continue as
      depositary for the Global Security or if at any time the Depositary is no
      longer eligible to be in good standing as a clearing agency registered
      under the Exchange Act, and we do not appoint a successor depositary
      within 90 days after we receive notice or become aware of the
      ineligibility or

    - We in our sole discretion at any time determine not to have all of the
      debt securities represented in an offering of Offered Debt Securities by a
      Global Security and notify the trustee thereof.

    A Global Security exchangeable pursuant to the preceding sentence shall be
exchangeable for debt securities registered in the names and in the authorized
denominations as the Depositary for the Global Security shall direct. The debt
securities of a series may also be issued in the form of one or more bearer
global debt securities (a "Bearer Global Security") that will be deposited with
a common depositary for Euroclear and Clearstream, or with a nominee for that
depositary identified in the prospectus supplement relating to the series. The
specific terms and procedures, including the specific terms of the depositary
arrangement, with respect to any portion of a series of debt securities to be
represented by a Bearer Global Security will be described in the prospectus
supplement.

SENIOR DEBT SECURITIES

    The payment of principal, premium, if any, and interest on the Senior Debt
Securities will, to the extent and in the manner set forth in the Senior Debt
Indenture, rank equally with all unsecured and unsubordinated debt.

SUBORDINATION OF SENIOR SUBORDINATED DEBT SECURITIES

    The payment of principal, premium, if any, and interest on the Senior
Subordinated Debt Securities will, to the extent and in the manner set forth in
the Senior Subordinated Debt Indenture, be subordinated in right of payment to
the prior payment in full, in cash equivalents, of all Senior Debt.

    Upon any payment or distribution of assets to our creditors upon any
liquidation, dissolution, winding up, receivership, reorganization, assignment
for the benefit of creditors, marshaling of assets and liabilities or

                                       21

any bankruptcy, insolvency or similar proceedings, the holders of all Senior
Debt will first be entitled to receive payment in full of all amounts due or to
become due thereon before the holders of the Senior Subordinated Debt Securities
will be entitled to receive any payment in respect of the principal, premium, if
any, or interest on the Senior Subordinated Debt Securities.

    No payments of principal, premium, if any, or interest in respect of the
Senior Subordinated Debt Securities may be made by us if a default in any
payment with respect to Senior Debt has occurred and is continuing. In addition,
during the continuance of any other event of default (other than a payment
default) with respect to Designated Senior Debt pursuant to which the maturity
thereof may be accelerated, no payments of principal, premium, if any, or
interest in respect of the Senior Subordinated Debt Securities may be made by us
for a period (the "Payment Blockage Period") beginning on the date of delivery
of written notice of the holders and ending 179 days thereafter (unless the
Payment Blockage Period shall be terminated by written notice to the trustee
from the holders of Designated Senior Debt or from an agent of these holders, or
the event of default has been cured or waived or has ceased to exist). Only one
Payment Blockage Period may be commenced with respect to the Senior Subordinated
Debt Securities during any period of 360 consecutive days. No event of default
which existed or was continuing on the date of the beginning of any Payment
Blockage Period shall be the basis for the beginning of any subsequent Payment
Blockage Period by the holders of Designated Senior Debt, unless such event of
default shall have been cured or waived for a period of not less than 90 days.

    Due to this subordination, in the event of insolvency, funds that would
otherwise be payable to holders will be paid to the holders of Senior Debt to
the extent necessary to pay the Senior Debt in full, and we may be unable to
meet fully our obligations with respect to the Senior Subordinated Debt
Securities.

    "Debt" is defined to mean, with respect to any person at any date of
determination (without duplication):

    - all indebtedness for borrowed money;

    - all obligations evidenced by bonds, debentures, notes or other similar
      instruments;

    - all obligations in respect of letters of credit or bankers' acceptance or
      other similar instruments (or reimbursement obligations with respect
      thereto);

    - all obligations to pay the deferred purchase price of property or
      services, except trade payables;

    - all obligations as lessee under capitalized leases;

    - all Debt of others secured by a lien on any asset of the person, whether
      or not the Debt is assumed by that person; provided that, for purposes of
      determining the amount of any Debt of the type described in this clause,
      if recourse with respect to that Debt is limited to that asset, the amount
      of that Debt shall be limited to the lesser of the fair market value of
      the asset or the amount of the Debt;

    - all Debt of others guaranteed by that person to the extent that Debt is
      guaranteed by such person;

    - all redeemable stock valued at the greater of its voluntary or involuntary
      liquidation preference plus accrued and unpaid dividends; and,

    - to the extent not otherwise included in this definition, all obligations
      under currency agreements and interest rate agreements.

    "Designated Senior Debt" is defined to mean:

    - Debt under the Credit Agreement dated as of August 2, 1996 (the "Credit

                                       22

      Agreement") among The AES Corporation, the banks named on the signature
      pages thereof and the Morgan Guaranty Trust Company of New York, as agent
      for the banks, as such Credit Agreement has been and may be amended,
      restated, supplemented or otherwise modified from time to time; and

    - Debt constituting Senior Debt which, at the time of its determination

      - has an aggregate principal amount of at least $30 million; and

      - is specifically designated by us as "Designated Senior Debt."

    "Senior Debt" is defined to mean the principal of, premium, if any, and
interest on all of our Debt whether created, incurred or assumed before, on or
after the date of the Senior Subordinated Debt Indenture; provided that Senior
Debt shall not include:

    - our 8.875% Senior Subordinated Debentures due 2027, 8.50% Senior
      Subordinated Notes due 2007, 8.375% Senior Subordinated Notes Due 2007 and
      our 10.25% Senior Subordinated Notes due 2006 which rank equally with the
      Senior Subordinated Debt Securities;

    - our Debt to any affiliate;

    - Debt of ours that, when incurred, and without respect to any election
      under Section 1111(b) of Title 11, U.S. Code, was without recourse;

    - any other Debt of ours which by the terms of the instrument creating or
      evidencing the same are specifically designated as not being senior in
      right of payment to the Senior Subordinated Debt Securities; and

    - our redeemable stock.

SUBORDINATION OF JUNIOR SUBORDINATED DEBT SECURITIES

    The payment of principal, premium, if any, and interest on the Junior
Subordinated Debt Securities will, to the extent and in the manner set forth in
the Junior Subordinated Debt Indenture, be subordinated in right of payment to
the prior payment in full, in cash or cash equivalents, of all our Senior and
Subordinated Debt.

    Upon any payment or distribution of assets to our creditors upon any
liquidation, dissolution, winding up, receivership, reorganization, assignment
for the benefit of creditors, marshaling of assets and liabilities or any
bankruptcy, insolvency or similar proceedings, the holders of all Senior and
Subordinated Debt will first be entitled to receive payment in full of all
amounts due or to become due thereon before the holders of the Junior
Subordinated Debt Securities will be entitled to receive any payment in respect
of the principal, premium, if any, or interest on the Junior Subordinated Debt
Securities.

    No payments of principal, premium, if any, or interest in respect of the
Junior Subordinated Debt Securities may be made by us if a default in any
payment with respect to Senior and Subordinated Debt has occurred and is
continuing. In addition, during the continuance of any other event of default
(other than a payment default) with respect to Designated Senior and
Subordinated Debt pursuant to which the maturity thereof may be accelerated, no
payments on account of principal, premium, if any, or interest may be made by us
during a Payment Blockage Period in respect of these Junior Subordinated Debt
Securities (unless the Payment Blockage Period is terminated by written notice
to the trustee from the holders of Designated Senior and Subordinated Debt or
from an agent of such holders, or the event of default has been cured or waived
or has ceased to exist). Only one Payment Blockage Period may be commenced with
respect to the Junior Subordinated Debt Securities during any period of 360
consecutive days. No event of default which existed or was continuing on the
date of the beginning of any Payment Blockage Period with respect to the
Designated Senior and Subordinated Debt initiating the Payment Blockage Period
shall be the basis for the beginning of any subsequent Payment Blockage Period
by the holders of such Designated Senior and Subordinated Debt, unless such
event of

                                       23

default shall have been cured or waived for a period of not less than 90
consecutive days.

    Due to this subordination, in the event of insolvency, funds that would
otherwise be payable to holders of Junior Subordinated Debt Securities will be
paid to the holders of Senior and Subordinated Debt to the extent necessary to
pay the Debt in full, and we may be unable to meet fully our obligations with
respect to the Junior Subordinated Debt Securities.

    "Designated Senior and Subordinated Debt" is defined to mean

    - Debt under the Credit Agreement; and

    - Debt constituting Senior and Subordinated Debt which, at the time of its
      determination

    - has an aggregate principal amount of at least $30 million; and

    - is specifically designated in the instrument as "Designated Senior and
      Subordinated Debt" by us.

    "Senior and Subordinated Debt" is defined to mean the principal, premium, if
any, and interest on all of our Debt whether created, incurred or assumed
before, on or after the date of the Junior Subordinated Debt Indenture; provided
that Senior and Subordinated Debt shall not include

    - our Debt to any affiliate;

    - Debt of ours that, when incurred and without respect to any election under
      Section 1111(b) of Title 11, U.S. Code, was without recourse;

    - any other Debt of ours which by the terms of the instrument creating or
      evidencing the same are specifically designated as not being senior in
      right of payment to the Junior Subordinated Debt Securities, and in
      particular the Junior Subordinated Debt Securities shall rank equally with
      all other debt securities and guarantees issued to an AES Trust or any
      other trust, partnership or other entity affiliated with us which is a
      financing vehicle of ours in connection with an issuance of preferred
      securities by that financing entity and

    - our redeemable stock.

EVENTS OF DEFAULT

    An Event of Default, as defined in the Indentures and applicable to debt
securities issued thereunder, will occur with respect to the debt securities of
any series issued under the Indentures if:

    1.  we default in paying principal or premium, if any, on any debt security
        when due, upon acceleration, redemption, mandatory repurchase, or
        otherwise;

    2.  we default in paying interest on any debt security when it becomes due,
        and the default continues for a period of 30 days;

    3.  we default in performing or breach any other covenant or agreement in
        the Indentures and the default or breach continues for a period of 60
        consecutive days after written notice by the trustee or by the holders
        of 25% or more in aggregate principal amount of the debt securities of
        all series issued under an Indenture;

    4.  a court having jurisdiction enters a decree or order for

        - relief in respect of AES or any of our Material Subsidiaries in an
          involuntary case under any applicable bankruptcy, insolvency, or other
          similar law now or hereafter in effect;

        - appointment of a receiver, liquidator, assignee, custodian, trustee,
          sequestrator, or similar official of AES or any of our Material
          Subsidiaries or for all or substantially all of the property and
          assets of AES or any of our Material Subsidiaries or

        - the winding up or liquidation of the affairs of AES or any of our
          Material

                                       24

          Subsidiaries and, in each case, such decree or order shall remain
          unstayed and in effect for a period of 60 consecutive days;

    5.  AES or any of its Material Subsidiaries

        - commences a voluntary case under any applicable bankruptcy,
          insolvency, or other similar law now or hereafter in effect, or
          consents to the entry of an order for relief in an involuntary case
          under any such law,

        - consents to the appointment of or taking possession by a receiver,
          liquidator, assignee, custodian, trustee, sequestrator, or similar
          official of AES or any of its Material Subsidiaries or for all or
          substantially all of the property and assets of AES or any of its
          Material Subsidiaries or

        - effects any general assignment for the benefit of creditors; or

    6.  any other Events of Default set forth in the applicable prospectus
        supplement occur.

    If an Event of Default (other than an Event of Default specified in
clause (4) or (5) with respect to AES) occurs with respect to the debt
securities of any series and continues, then the trustee or the holders of at
least 25% in principal amount of the outstanding debt securities may, by written
notice to us, and the trustee at the request of at least 25% in principal amount
of the outstanding debt securities will, declare the principal, premium, if any,
and accrued interest on the outstanding debt securities to be immediately due
and payable. Upon a declaration of acceleration, the principal, premium, if any,
and accrued interest shall be immediately due and payable.

    If an Event of Default specified in clause (4) or (5) above occurs with
respect to AES, the principal, premium, if any, and accrued interest on the debt
securities shall be immediately due and payable, subject to the prior payment in
full of all Senior Debt, without any declaration or other act on the part of the
trustee or any holder. The holders of at least a majority in principal amount of
the outstanding debt securities may, by written notice to us and to the trustee,
waive all past defaults with respect to debt securities and rescind and annul a
declaration of acceleration with respect to debt securities of that series and
its consequences if:

    - all existing Events of Default applicable to debt securities of that
      series, other than the nonpayment of the principal, premium, if any, and
      interest on the debt securities that have become due solely by that
      declaration of acceleration, have been cured or waived and

    - the rescission would not conflict with any judgment or decree of a court
      of competent jurisdiction.

    For information as to the waiver of defaults, see "--Modification and
Waiver."

    The holders of at least a majority in principal amount of the outstanding
debt securities may direct the time, method, and place of conducting any
proceeding for any remedy available to the trustee or exercising any trust or
power conferred on the trustee. However, the trustee may refuse to follow any
direction that conflicts with law or the applicable Indenture, that may involve
the trustee in personal liability, or that the trustee determines in good faith
may be unduly prejudicial to the rights of holders of debt securities who did
not join in giving that direction and the trustee may take any other action it
deems proper that is not inconsistent with the direction received from holders
of outstanding debt securities. A holder may not pursue any remedy with respect
to the applicable Indenture or the debt securities of any series unless:

    - the holder gives the trustee written notice of a continuing Event of
      Default;

    - the holders of at least 25% in principal amount of outstanding debt
      securities make a written request to the trustee to pursue the remedy;

    - the holder or holders offer and, if requested, provide the trustee
      indemnity satisfactory to the trustee against any costs, liability or
      expense;

                                       25

    - the trustee does not comply with the request within 60 days after receipt
      of the request and the offer of indemnity and

    - with that 60-day period, the holders of at least a majority in principal
      amount of the outstanding debt securities do not give the trustee a
      direction that is inconsistent with the request.

    However, these limitations do not apply to the right of any holder of a debt
security to receive payment of the principal, premium, if any, or interest on,
that debt security or to bring suit for the enforcement of any payment, on or
after the due date expressed in the debt securities, which right shall not be
impaired or affected without the consent of the holder.

    Each of the Indentures requires that certain of our officers certify, on or
before a date not more than four months after the end of each fiscal year, that
to the best of those officers' knowledge, we have fulfilled all our obligations
under the Indenture. We are also obligated to notify the trustee of any default
or defaults in the performance of any covenants or agreements under any of the
Indentures.

    "Material Subsidiary" of a Person is defined to mean, as of any date, any
Subsidiary that would constitute a "significant subsidiary" within the meaning
of Article 1 of Regulation S-X of the Securities Act of 1933.

    "Subsidiary" means, with respect to any Person, any corporation, association
or other business entity of which a majority of the capital stock or other
ownership interests having ordinary voting power to elect a majority of the
board of directors or other persons performing similar functions are at the time
directly or indirectly owned by such Person.

    "Person" means an individual, a corporation, a partnership, a limited
liability company, an association, a trust or any other entity or organization,
including a government or political subdivision or an agency or instrumentality
thereof.

MODIFICATION AND WAIVER

    The Indentures may be amended or supplemented without the consent of any
holder of debt securities to:

    - cure ambiguities, defects, or inconsistencies;

    - comply with the terms in "Restriction on Mergers, Consolidations and Sales
      of Assets" described below;

    - comply with any requirements of the Securities and Exchange Commission in
      connection with the qualification of the Indentures under the Trust
      Indenture Act of 1939;

    - evidence and provide for the acceptance of appointment with respect to the
      debt securities by a successor Trustee;

    - establish the form or forms of debt securities of any series;

    - provide for uncertificated debt securities and to make all appropriate
      changes for such purpose; and

    - make any change that does not adversely affect the rights of any holder.

    Other modifications and amendments of the Indentures may be made with the
consent of the holders of not less than a majority in principal amount of the
outstanding debt securities of each series affected by the amendment (all such
series voting together as a single class). However, no modification or amendment
may, without the consent of each holder affected:

    - change the stated maturity of the principal of, or any sinking fund
      obligation or any installment of interest on, any debt security;

    - reduce the principal amount, premium, if any, or interest on, any debt
      security;

    - reduce the above-stated percentage of outstanding debt securities, the
      consent of whose holders is necessary to modify or

                                       26

      amend that Indenture with respect to the debt securities of any series
      issued under that Indenture;

    - reduce the percentage or principal amount of outstanding debt securities,
      the consent of whose holders is necessary for waiver of compliance with
      certain provisions of that Indenture or for waiver of certain defaults.

    A supplemental indenture which changes or eliminates any covenant or other
provision of an Indenture which has expressly been included solely for the
benefit of one or more particular series of debt securities issued under an
Indenture, or which modifies the rights of holders of debt securities of that
series with respect to that covenant or provision, shall be deemed not to affect
the rights under the applicable Indenture of the holders of debt securities of
any other series issued under the Indenture or of the coupons appertaining to
those debt securities. It is not necessary for the consent of the holders under
this section of an Indenture to approve the particular form of any proposed
amendment, supplement, or waiver, but it is sufficient if the consent approves
the substance thereof. After an amendment, supplement, or waiver under this
section of an Indenture becomes effective, we will give to the holders affected
thereby a notice briefly describing the amendment, supplement, or waiver. We
will mail supplemental indentures to holders upon request. Any failure of us to
mail a notice, or any defect therein, will not affect the validity of any
supplemental indenture or waiver.

RESTRICTION ON MERGERS, CONSOLIDATIONS AND SALES OF ASSETS

    Pursuant to the Indentures, we may not consolidate with, merge with or into,
or transfer all or substantially all of our assets to any Person unless:

    - AES shall be the continuing Person, or, if AES is not the continuing
      Person, the Person formed by such consolidation or into which we merged or
      to which properties and assets of ours are transferred is a solvent
      corporation organized and existing under the laws of the United States or
      any State thereof or the District of Columbia and expressly assumes in
      writing all the obligations of ours under the Notes,

    - immediately after giving effect to such transaction no Event of Default
      has occurred and is continuing and

    - other conditions as may be established in connection with the issuance of
      the applicable Debt Securities are met.

DEFEASANCE AND DISCHARGE

    The Indentures provide that we are deemed to have paid and will be
discharged from all obligations in respect of the debt securities of any series
on the 123rd day after the deposit referred to below has been made, and that the
provisions of an Indenture will no longer be in effect with respect to the debt
securities issued thereunder (except for, among other matters, certain
obligations to register the transfer or exchange of the Debt Securities of such
series, to replace stolen, lost or mutilated Debt Securities of such series, to
maintain paying agencies and to hold monies for payment in trust) if, among
other things,

    - we have deposited with the trustee, in trust, money and/or U.S. Government
      Obligations that through the payment of interest and principal in respect
      thereof, will provide money in an amount sufficient to pay the principal,
      premium, if any, and accrued interest on the applicable debt securities,
      on the due date thereof or earlier redemption (irrevocably provided for
      under arrangements satisfactory to the trustee), as the case may be, in
      accordance with the terms of the Indenture and the applicable debt
      securities,

    - we have delivered to the trustee

      - either

            -- an opinion of counsel to the effect that holders will not
               recognize income, gain or loss for federal income tax purposes as
               a result of the exercise of

                                       27

               our option under this "Defeasance" provision and will be subject
               to federal income tax on the same amount and in the same manner
               and at the same times as would have been the case if the deposit,
               defeasance and discharge had not occurred, which opinion of
               counsel must be based upon a ruling of the Internal Revenue
               Service to the same effect unless there has been a change in
               applicable federal income tax law or related treasury regulations
               after the date of the Indenture that a ruling is no longer
               required or

            -- a ruling directed to the trustee received from the Internal
               Revenue Service to the same effect as the aforementioned opinion
               of counsel and

    - an opinion of counsel to the effect that the creation of the defeasance
      trust does not violate the Investment Company Act of 1940 and after the
      passage of 123 days following the deposit, the trust fund will not be
      subject to the effect of Section 547 of the U.S. Bankruptcy Code or
      Section 15 of the New York Debtor and Creditor Law,

    - immediately after giving effect to that deposit on a pro forma basis, no
      Event of Default has occurred and is continuing on the date of the deposit
      or during the period ending on the 123rd day after the date of the
      deposit, and the deposit will not result in a breach or violation of, or
      constitute a default under, any other agreement or instrument to which we
      are a party or by which we are bound,

    - we are not prohibited from making payments in respect of the applicable
      debt securities by the subordination provisions contained in an Indenture
      and

    - if at that time the applicable debt securities are listed on a national
      securities exchange, we have delivered to the trustee an opinion of
      counsel to the effect that the debt securities will not be delisted as a
      result of a deposit, defeasance and discharge.

    As more fully described in the prospectus supplement, the Indentures also
provide for defeasance of certain covenants.

        DESCRIPTION OF STOCK PURCHASE CONTRACTS AND STOCK PURCHASE UNITS

    We may issue Stock Purchase Contracts, which represent contracts obligating
holders to purchase from us a specified number of shares of common stock at a
future date or dates. The price per share of common stock may be fixed at the
time the stock purchase contracts are issued or may be determined by reference
to a specific formula described in the stock purchase contracts. The stock
purchase contracts may be issued separately or as a part of units ("Stock
Purchase Units") consisting of a stock purchase contract and debt securities or
debt obligations of third parties, including U.S. Treasury securities, securing
the holders' obligations to purchase the common stock under the stock purchase
contracts. The stock purchase contracts may require us to make periodic payments
to the holders of the stock purchase units or vice versa, and these payments may
be unsecured or prefunded on some basis. The stock purchase contracts may
require holders to secure their obligations thereunder in a specified manner.

    The prospectus supplement will describe the terms of any stock purchase
contracts or stock purchase units. The description in the prospectus supplement
will not be complete and will be qualified by reference to the stock purchase
contracts, and, if applicable, additional arrangements, relating to the stock
purchase contracts or stock purchase units.

                                       28

                       DESCRIPTION OF SECURITIES WARRANTS

    We may issue securities warrants for the purchase of debt securities,
preferred stock or common stock. Securities warrants may be issued independently
or together with debt securities, preferred stock or common stock and may be
attached to or separate from any offered securities. Each series of securities
warrants will be issued under a separate warrant agreement to be entered into
between us and a bank or trust company, as warrant agent. The securities warrant
agent will act solely as our agent in connection with the securities warrants
and will not assume any obligation or relationship of agency or trust for or
with any registered holders of securities warrants or beneficial owners of
securities warrants. This summary of some provisions of the securities warrants
is not complete. You should refer to the securities warrant agreement, including
the forms of securities warrant certificate presenting the securities warrants,
relating to the specific securities warrants being offered for the complete
terms of the securities warrant agreement and the securities warrants. That
securities warrant agreement, together with the terms of securities warrant
certificate and securities warrants, will be filed with the Securities and
Exchange Commission in connection with the offering of the specific securities
warrants.

    The particular terms of any issue of securities warrants will be described
in the prospectus supplement relating to the issue. Those terms may include:

    - the designation, aggregate principal amount, currencies, denominations and
      terms of the series of debt securities purchasable upon exercise of
      securities warrants to purchase debt securities and the price at which the
      debt securities may be purchased upon exercise;

    - the designation, number of shares, stated value and terms (including,
      without limitation, liquidation, dividend, conversion and voting rights)
      of the series of preferred stock purchasable upon exercise of securities
      warrants to purchase shares of preferred stock and the price at which such
      number of shares of preferred stock of such series may be purchased upon
      such exercise;

    - the number of shares of common stock purchasable upon the exercise of
      securities warrants to purchase shares of common stock and the price at
      which such number of shares of common stock may be purchased upon such
      exercise;

    - the date on which the right to exercise the securities warrants will
      commence and the date on which the right will expire;

    - United States Federal income tax consequences applicable to the securities
      warrants; and

    - any other terms of the securities warrants.

    Securities warrants for the purchase of preferred stock and common stock
will be offered and exercisable for U.S. dollars only. Securities warrants will
be issued in registered form only. The exercise price for securities warrants
will be subject to adjustment in accordance with the applicable prospectus
supplement.

    Each securities warrant will entitle its holder to purchase the principal
amount of debt securities or the number of shares of preferred stock or common
stock at the exercise price set forth in, or calculable as set forth in, the
applicable prospectus supplement. The exercise price may be adjusted upon the
occurrence of certain events as set forth in the prospectus supplement. After
the close of business on the expiration date, unexercised securities warrants
will become void. We will specify the place or places where, and the manner in
which, securities warrants may be exercised in the applicable prospectus
supplement.

    Prior to the exercise of any securities warrants to purchase debt
securities, preferred stock or common stock, holders of the securities warrants
will not have any of the rights of holders of the debt securities, preferred
stock or

                                       29

common stock purchasable upon exercise, including:

    - in the case of securities warrants for the purchase of debt securities,
      the right to receive payments of principal of, any premium or interest on
      the debt securities purchasable upon exercise or to enforce covenants in
      the applicable indenture; or

    - in the case of securities warrants for the purchase of preferred stock or
      common stock, the right to vote or to receive any payments of dividends on
      the preferred stock or common stock purchasable upon exercise.

                              PLAN OF DISTRIBUTION

    We may sell the securities in any of three ways (or in any combination
thereof):

    - through underwriters or dealers;

    - directly to a limited number of purchasers or to a single purchaser; or

    - through agents.

    The prospectus supplement will set forth the terms of the offering of such
securities, including

    - the name or names of any underwriters, dealers or agents and the
      respective amounts of securities underwritten or purchased by each of
      them,

    - the initial public offering price of the securities and the proceeds to us
      and any discounts, commissions or other items constituting compensation
      from us and any discounts, commissions or concessions allowed or reallowed
      or paid to dealers and any securities exchanges on which the securities
      may be listed.

    Any initial public offering price and any discounts or concessions allowed
or reallowed or paid to dealers may be changed from time to time.

    If underwriters are used in the sale of any securities, the securities will
be acquired by the underwriters for their own account and may be resold from
time to time in one or more transactions, including negotiated transactions, at
a fixed public offering price or at varying prices determined at the time of
sale. The securities may be either offered to the public through underwriting
syndicates represented by managing underwriters, or directly by underwriters.
Unless otherwise described in the prospectus supplement, the obligations of the
underwriters to purchase the securities will be subject to certain conditions
and the underwriters will be obligated to purchase all of the securities if any
are purchased.

    If a dealer is utilized in the sale of any offered securities, we will sell
those securities to the dealer, as principal. The dealer may then resell the
offered securities to the public at varying prices to be determined by the
dealer at the time of resale.

    Offered Securities may be sold directly by us or through agents designated
by us from time to time. Any agent involved in the offer or sale of Offered
Securities in respect of which this Prospectus is delivered will be named, and
any commissions payable by us to such agent will be set forth, in the prospectus
supplement. Unless otherwise indicated in the prospectus supplement, any such
agent will be acting on a best efforts basis for the period of its appointment.

    We may authorize underwriters, dealers or agents to solicit offers by
certain purchasers to purchase the securities from us at the public offering
price set forth in the prospectus supplement pursuant to delayed delivery
contracts providing for payment and delivery on a specified date in the future.
These contracts will be subject only to those conditions set forth in the
prospectus supplement, and the prospectus supplement will set forth the
commission payable for solicitation of such contracts.

    Agents and underwriters may be entitled to indemnification by us against
certain civil liabilities, including liabilities under the

                                       30

Securities Act, or to contribution with respect to payments which the agents or
underwriters may be required to make in respect thereof. Agents and underwriters
may be customers of, engage in transactions with, or perform services for us in
the ordinary course of business.

                                 LEGAL MATTERS
