Alamitos repower project of AES wins contract, will need revamping

California Enegy Commission staff in a Feb. 13 memo told the commissioners presiding over an approval process for the Alamitos Energy Center project of AES Corp. (NYSE: AES) that the project will need to be totally revamped.

“On November 5, 2014, AES was awarded a Power Purchase Agreement for the Alamitos Energy Center (AEC), with different equipment, configuration, and fewer megawatts than the information submitted to the Commission in the Application for Certification (AFC),” said the memo. “AES is currently developing an engineering design required to prepare a Supplemental Application for Certification (SAFC).

“Staff and the Applicant met on January 27, 2015, to exchange information about the project and alert the applicant to information that staff would expect to see in the SAFC. The Applicant informed staff that the revised AEC project would consist of 1,040 MW, with one 640-MW air cooled combined-cycle power block, employing two GE Frame 7 Fas and a steam turbine, and an additional four LMS-100 PB simple-cycle combustion turbine generators. Submittal of the SAFC is expected in August-September 2015. The commercial operation date for the Power Purchase Agreement signed with [Southern California Edison] would be March 1, 2020.”

In December 2013, AES Southland Development LLC submitted the AFC to modernize the existing Alamitos Generating Station. The replacement Alamitos Energy Center (AEC) would be located on about 63 acres of privately-owned land in the City of Long Beach, Los Angeles County, California.

As originally proposed, the AEC would have been a natural-gas-fired, fast-starting, combined-cycle, air-cooled facility with a net capacity of 1,936 MW. AEC would under that configuration have consisted of four 3-on-1 combined-cycle gas turbine power blocks, with twelve natural-gas-fired combustion turbine generators, twelve heat recovery steam generators, four steam turbine generators, four air-cooled condensers, and related ancillary equipment.
