More information on SDG&E’s Battery Storage Facility in Escondido:

On Feb 24, 2017, SDG&E unveiled, at the time, the World’s Largest Lithium Ion Battery Storage Facility in Escondido. Recently, this same project was honored with the Energy Storage North America (ESNA) 2017 Innovation Award for outstanding achievement.

The California Public Utility Commission (CPUC) directed Southern California investor-owned electric utilities to fast-track additional energy storage options to enhance regional energy reliability.

In response, SDG&E contracted AES Energy Storage to build two projects for a total of 37.5 MW/150 MWh of lithium ion battery energy storage. In addition to the 30 MW facility built in Escondido, Calif., a smaller 7.5 MW installation was also built in El Cajon.

The 400,000 battery cells, similar to those in electric vehicles, were installed in nearly 20,000 modules and placed in 24 containers.  The batteries act like a sponge, soaking up and storing energy when it is abundant – when the sun is shining, the wind is blowing and energy use is low – and releasing it when energy resources are in high demand.  This provides reliable energy when customers need it most, and maximizes the use of renewable resources such as solar and wind.
