Mirant Announces Closing $650 Million Project Financing for Marsh Landing Generating Station

Construction of New Units to Begin Later this Year

ATLANTA – Mirant Corporation (NYSE: MIR) announced today that its subsidiary, Mirant Marsh Landing, LLC, closed last Friday on a $650 million credit facility to provide construction and permanent financing for its Marsh Landing Generating Station. The credit facility includes $500 million of construction and term debt and $150 million of letter of credit facilities. The letter of credit facilities will satisfy the debt service reserve required by the new credit facility and the performance security requirements under the project’s power purchase agreement with Pacific Gas and Electric Company (PG&E). The term debt will be repaid over the ten year term of the power purchase agreement.

“We are pleased to be moving forward with efficient new units to provide a reliable new source of generation to meet the electricity demands of the San Francisco Bay Area,” said Edward R. Muller, Mirant’s Chairman and CEO.

Mirant Marsh Landing, LLC has received all permits necessary to begin construction and has directed Kiewit Power Constructors Co. to commence engineering and procurement for the project. Construction is scheduled to begin later this year and to be completed by mid-2013. The total cost of the station is expected to be approximately $700 million.


The Marsh Landing Generating Station will be a 760 MW natural gas-fired peaking facility to be located adjacent to Mirant’s existing Contra Costa Generating Station near Antioch, California. Marsh Landing will utilize existing gas and electric transmission infrastructures and incorporate best available control technology.

Mirant is a competitive energy company that produces and sells electricity in the United States. Mirant owns or leases more than 10,000 megawatts of electric generating capacity. The company operates an asset management and energy marketing organization from its headquarters in Atlanta. For more information, please visit www.mirant.com.

CAUTIONARY LANGUAGE REGARDING FORWARD-LOOKING STATEMENTS

Some of the statements included herein involve forward-looking information. Mirant cautions that these statements involve known and unknown risks and that there can be no assurance that such results will occur. There are various important factors that could cause actual results to differ materially from those indicated in the forward-looking statements, such as, but not limited to the inability to complete construction of the Mirant Marsh Landing Generating Station by mid-2013; the ability of lenders under the Marsh Landing credit facility to perform their obligations; restrictions on the ability of Mirant’s subsidiaries to pay dividends, make distributions or otherwise transfer funds to Mirant, including restrictions on Mirant North America contained in its financing agreements and restrictions on Mirant Mid-Atlantic contained in its leveraged lease documents, which may affect Mirant’s ability to access the cash flows of those subsidiaries to make debt service and other payments; the failure to comply with, or monitor provisions of Mirant’s loan agreements and debt may lead to a breach and, if not remedied, result in an event of default thereunder, which would limit access to needed capital and damage Mirant’s reputation and relationships with financial institutions; and the risks and uncertainties described in Mirant’s Form 10-K for the year ended December 31, 2009 and Mirant’s Form 10-Q for the quarter ended June 30, 2010, filed with the Securities and Exchange Commission (“SEC”).
