PITTSBURGH, Oct. 31, 2025 (GLOBE NEWSWIRE) -- Eos Energy Enterprises, Inc. (NASDAQ: EOSE) ("Eos" or the “Company”), an American energy company and the leading innovator in designing, sourcing, manufacturing, and providing zinc-based battery energy storage systems (BESS) and Frontier Power Ltd. (“Frontier”), a leading UK-based energy developer, today announced a strategic 228 megawatt-hour (MWh) order to deploy Eos Z3™ energy storage systems across Frontier’s expanding portfolio of storage and grid-reliability projects.
The 228 MWh order – the first to be converted under the companies’ 5 GWh framework agreement announced in April 2025 – marks a significant milestone in a growing partnership focused on scaling alternative, long-duration energy storage to strengthen grid reliability across multiple markets.
“This order reflects continued confidence in Eos’ zinc technology and the strength of our partnership with Frontier,” said Nathan Kroeker, Eos Chief Commercial Officer. “Together, we’re demonstrating that long-duration storage is ready to scale and play a critical role in delivering reliable dispatchable power.”
Frontier will deploy Eos’ Z3™ energy storage systems, featuring the Company’s proprietary battery management system, software, controls and analytics platform – DawnOS™ – to validate performance and reliability in diverse grid environments. This provides a unique opportunity to showcase Eos’ technology ahead of Frontier’s upcoming projects under Ofgem’s Cap-and-Floor program.
Frontier recently advanced 11 gigawatt-hours (GWh) of long-duration storage projects to the second round of the program, all incorporating Eos’ technology and more than double the original commitment. This milestone highlights the growing market demand for 8-hour-plus storage and reinforces confidence in the companies’ joint ability to deliver commercially viable, large-scale solutions.
“Our partnership with Eos goes beyond a single project – it’s about building a platform for long-duration storage at scale,” said Humza Malik, Frontier Chief Executive Officer. “Together, we’re demonstrating how innovative, safe, and sustainable zinc technology can support renewable growth and deliver dependable, flexible power for the grid of the future.”
Eos’ Z3™ technology builds on the company’s proven zinc-based chemistry, offering enhanced energy density, extended duration, and a safe, non-flammable solution ideal for long-life, grid-scale applications. As the partnership grows, Eos and Frontier are positioned to accelerate deployment of long-duration energy storage across key international markets, supporting renewable integration, grid stability, and global energy security.
The announcement coincides with the Company also achieving its final cash receipt milestone previously agreed upon between Eos and an affiliate of Cerberus Capital Management LP (Cerberus) as part of Cerberus’s strategic investment in the Company. No additional preferred stock or warrants will be issued to Cerberus at this time.
