What We Do

3rd Largest Geothermal Plant in U.S.A.

Coso Operating Company, LLC, has operated the Coso Geothermal Projects at the U.S. Naval Weapons Center in Inyo County since 1987.  Consisting of four separate but interlinked geothermal power plants, the Coso site is one of the top three producers of geothermal electrical power in the United States.  The company leases the geothermal site from the U.S. Navy and BLM.  The project has produced as much as 270 megawatts of electricity, enough power to supply 250,000 homes.

Coso provides power from its site to the Southern California Edison Co. (SCE) and plays an important part in the state’s efforts to reach its goal of meeting 50% of SCE’s power needs with renewable sources by 2030.  This premier resource supplies approximately 8% of the entire geothermal power in the United States.
