AES Announces Extension Agreement for Southland Legacy Units in California

Capacity Supports Grid Reliability as State Moves Toward Decarbonization

ARLINGTON, Va., April 26, 2023 /PRNewswire/ -- The AES Corporation (NYSE: AES) today announced that it has signed agreements with the California Department of Water Resources (DWR) to extend operations of the once-through cooling (OTC) units at its Huntington Beach and Alamitos facilities through 2026. The extension will help meet the state's grid reliability needs while supporting its decarbonization goals, and is subject to the State Water Resources Control Board extending the OTC compliance dates, anticipated in the second half of 2023.

"Our Southland legacy units continue to demonstrate that they are ready and able to support the reliability of California's electric grid," said Andrés Gluski, AES President and Chief Executive Officer. "At AES, we are committed to supporting the energy needs of local communities with flexible and innovative solutions."

The Southland legacy units include 2.3 GW of gas generating capacity in Southern California, across three facilities: Alamitos, Huntington Beach, and Redondo Beach. Operations for all OTC units are currently scheduled to expire in December 2023, at which time Redondo Beach will be retired. If the three-year extensions for the 1.4 GW at Huntington Beach and Alamitos are approved, AES will continue to operate these OTC units during emergency grid reliability events within the Strategic Reliability Reserve Program as outlined in AB205, legislation that sets out state initiatives to ensure grid reliability as it moves toward a zero-carbon energy future.
