# Edwards Sanborn E1B

CAISO Batteries, Solar Photovoltaic · https://askthegrid.com/assets/facilities/edwards-sanborn-e1b

Edwards Sanborn E1B is a hybrid solar and battery storage facility with 290.4 MW of EIA-reported total operating capacity and 136 MWh of reported storage energy capacity in Kern County, California, registered as EIA Plant ID 65674. Terra-Gen Operating Co-Hybrid is the registered plant entity or operator. Edwards Sanborn E1B is a phase of the broader Edwards Sanborn solar-plus-storage development, which has been described as one of the largest solar-and-storage facilities in the world and as a major contributor to the CAISO grid. The broader development was also described as the largest public-private collaboration in U.S. Department of Defense history; these distinctions apply to the combined development rather than to E1B alone.
