The proposed BOTTLE ROCK POWER project is a 56.88 MW hybrid geothermal and battery energy storage system located in Lake County, California. The project, developed under the CAISO queue as queue ID CAISO-81, consists of a 9.44 MW geothermal component and a 47.45 MW battery component. The project is interconnected to the PG&E utility via the Geysers #17-Fulton 230 kV Line.
The project entered the CAISO interconnection queue on September 13, 2005, and has a proposed commercial operation date of November 30, 2027. An Interconnection Agreement (IA) was executed on November 16, 2006. The BOTTLE ROCK POWER project has been mentioned in recent news coverage.
