"We were in the process of a competitive solicitation for energy storage and already had completed a pre-evaluation of respondents," said James P. Avery, SDG&E's chief development officer. "As a result, we could move quickly to respond to the CPUC's request for expedited proposals."
In mid-July, SDG&E signed an agreement with AES for a total of 37.5 megawatts (MW) of lithium-ion battery storage. AES is a major supplier of advanced storage technology and other energy resources around the world.
SDG&E will own the storage projects that AES will build on utility-owned property in Escondido and El Cajon. The larger of the two will be a 30-MW unit and the smaller will be a 7.5-MW unit.
Construction will begin immediately and should be completed in early 2017.
The CPUC requires SDG&E to procure a total of 165 MW of energy storage by 2020, to be operational by 2024.
SDG&E is a regulated public utility that provides safe and reliable energy service to 3.5 million consumers through 1.4 million electric meters and 873,000 natural gas meters in San Diego and southern Orange counties.
