Project Description

The Alamitos Energy Center (AEC) is located on approximately 21 acres of the 71-acre brownfield Alamitos Generating Station (AGS) site. The proposed project site is bounded to the north by State Route 22; to the east by the San Gabriel River; to the south by 2nd Street; and to the west by N. Studebaker Rd., in the city of Long Beach, Los Angeles County, California.

On December 27, 2013, AES Southland Development, LLC (AES-SD) submitted an Application for Certification (AFC) to modernize the existing AGS. The original AFC proposed a natural gas-fired, fast starting, combined-cycle gas turbines, air-cooled electrical generating facility with a net generating capacity of 1,936-megawatt (MW), to replace, and be constructed on the AGS site.

On October 26, 2015, AES-SD submitted a Supplemental Application for Certification (SAFC) (13-AFC-01) to address significant revisions to the design for modernizing the existing AGS. The SAFC replaced the original AFC filed on December 27, 2013. The project description in the SAFC for the proposed AEC has changed from that in the AFC filed on December 27, 2013.

The revised proposed AEC would include a nominal 640 MW, natural gas-fired, combined-cycle power block and a 400 MW simple-cycle, air-cooled electrical generating facility. Power Block 1 would consist of two natural gas-fired combustion turbine generators (CTG) in a combined-cycle configuration with two unfired heat recovery steam generators, one steam turbine generator, an air-cooled condenser, an auxiliary boiler, and related ancillary equipment. Power Block 2 would consist of four simple-cycle CTGs with fin-fan coolers and ancillary facilities. Some common components for Phase 1 and Phase 2 have been constructed, but active construction on the 400 MW Phase 2 is not proceeding at this time.

Existing Alamitos Generating Station Units 1–6 are currently in operation with a net generating capacity of 1,950 megawatts (MW). Although AES still intends to demolish all six operating units, AES is no longer including the demolition as part of the proposed AEC project, but now plans to accomplish the demolition under a separate CEQA proceeding through a Memorandum of Understanding with the city of Long Beach.

Power Plant Certification and Exemption Processes

As required by the Warren-Alquist Act, the Energy Commission monitors Commission-certified energy projects throughout construction, operation, and closure to ensure compliance with the conditions of certification imposed by the Commission’s Final Decision for approving the projects.
