AES Breaks Ground on Alamitos Energy Center in California

LCG, July 25, 2017--AES Alamitos, a subsidiary of The AES Corporation (AES), broke ground Friday on the new Alamitos Energy Center (AEC), located in Long Beach, California. The facilities include a nominal 640-MW, natural gas-fired, combined cycle power block; four, natural gas-fired,100-MW, simple cycle units; plus a 100-MW battery energy storage system. The new facilities will be installed on approximately 21 acres of the existing 71-acre site, where the existing gas-fired, 1950s-era Alamitos Generating Station Units 1-6 currently provide a net generating capacity of 1,950 MW.

AES submitted its original application to modernize the existing Alamitos Generating Station on December 27, 2013. AES amended its application in September 2015, and the California Energy Commission (CEC) approved the license for the new facilities in April.

"We're excited to move forward to the construction phase of this important project and look forward to working with the community every step of the way," said the President of AES Alamitos Energy, LLC.

AES plans to decommission the existing power plants to comply with a 2010 California regulation constraining the use seawater for cooling at the plants. The new Alamitos Energy Center will eliminate the use of ocean water for cooling and reduce the use of fresh water by 70 percent.
