Edwards Sanborn (Edsan) Solar Storage Phase 1A & 1B

The initial phase of the EdSan 1A & 1B  solar facility is one of the largest solar-plus-storage projects in North America and is situated in Kern County, California. The facility is located on both private land as well as land leased from Edwards Air Force Base. In total, the project spans 4,600 acres and was awarded the Presidential Federal Sustainability Award for its advancement of Carbon-Free Electricity.

EdSan 1A and 1B both have significant energy storage components. This phase comprises 971 MW of energy storage, enough capacity to supply 971,000 homes for approximately 4 hours on a single charge

Construction began in 2020, with phases becoming operational throughout 2022 and 2023. The project has a solar energy capacity of 807 megawatts and a battery storage capacity of over 3 gigawatt hours. Collectively, this project can provide up to 1,252 MW of power to the grid.

Future project phases that are currently in development will interconnect additional solar and energy storage to the CAISO grid. When complete, the EdSan franchise will provide up to 3.9 gigawatts of solar storage onto the grid.
