AES Energy Storage, has entered into two contracts with San Diego Gas and Electric. AES will install and commission two energy storage arrays totaling 37.5 MW using its Advancion energy storage solution at sites in San Diego County, California. The SDG&E-owned energy storage arrays will help to improve regional reliability and integrate greater amounts of renewable energy when operational by the end of January 2017.

The SDG&E Advancion arrays will be able to provide 37.5 MW of power for four continuous hours and serve as a 75 MW of flexible resource to the grid. Both systems are distribution interconnected @ 12 kV and the arrays will be installed at two SDG&E substation facilities: 30 MW in Escondido and 7.5 MW in El Cajon. Once completed, the Escondido array will be the largest battery-based energy storage project in operation in the United States. Both arrays will incorporate components from best-in-class Advancion certified suppliers, including batteries by Samsung SDI and power conversion systems by Parker Hannifin.
