MOTION FOR PARTY STATUS OF AES SOUTHLAND DEVELOPMENT, LLC

Pursuant to Rule 1.4(a)(4) of the Commission’s Rules of Practice and Procedure, AES Southland Development, LLC hereby seeks party status in the above-referenced proceeding.

I. DESCRIPTION OF AES SOUTHLAND DEVELOPMENT, LLC

AES Southland Development, LLC is the parent company of AES Alamitos Energy, LLC, which owns the Alamitos Energy Center, a 640-megawatt (MW), natural gas-fired, combined- cycle power plant located on the site of the AES Alamitos Generating Station. AES Alamitos is also developing a 400 MWh battery energy storage system (BESS) at the same site. Alamitos Energy Center has a twenty-year power purchase agreement with Southern California Edison Company (SCE); the BESS also has a 20-year agreement with SCE to provide resource adequacy capacity. Both these assets provide critical local resource adequacy capacity in the Western LA Basin local capacity area. AES Southland Development, LLC is also the parent company of AES Huntington Beach Energy, LLC, which owns the Huntington Beach Energy Project, a 640 MW natural gas-fired, combined cycle power plant located at the site of the AES Huntington Beach Generating Station. Huntington Beach Energy Project also has a power purchase agreement with SCE, and also provides local resource adequacy capacity to the Western LA Basin local capacity area. Through subsidiaries, AES Southland Development, LLC also owns the remaining once- through-cooled generation at AES Alamitos Generating Station, Huntington Beach Generating

2 / 4 Station and Redondo Beach Generating Station. Those units were scheduled to retire in 2020, but the retirement dates have been extended due to the need for local resource adequacy capacity provided by these units. II. AES SOUTHLAND DEVELOPMENT’S INTEREST IN THE PROCEEDING

As the ultimate owner of several assets that provide critical local resource adequacy capacity, as well as flexible and system resource adequacy, AES Southland Development has a significant interest in the Commission’s ongoing development of the resource adequacy program.
