About

The REXFORD 2 SOLAR FARM is a proposed 400 MW hybrid solar and battery energy storage project located in Tulare County, California. The development project, consisting of 200 MW of solar photovoltaic generation and 200 MW of battery storage, is interconnected to the CAISO grid at the Vestal Substation 230kV. The project's queue ID is CAISO-1789, and it entered the CAISO interconnection queue on April 15, 2020, with a proposed commercial operation date of July 1, 2027. The project's interconnection status is currently in the System Impact Study phase.

The proposed project is in the service territory of Southern California Edison (SCE). Recent news coverage has highlighted the project, with articles appearing in grid and industry publications.
