On Friday, Southern California utility San Diego Gas & Electric (SDG&E) held a small press conference in Escondido to show off its brand new energy storage facility, a 30MW battery system capable of storing 120MWh of energy, which can serve 20,000 customers for four hours. SDG&E also introduced a 7.5MW battery system built in El Cajon, CA.
The two projects were built after state energy officials ordered power companies to add lithium-ion battery storage to their grids this past summer following a massive methane leak at Aliso Canyon in California that put the region in jeopardy for natural gas shortages. AES Energy Storage, a Virginia-based company that has been building utility-grade batteries since 2008, built the system for SDG&E.
