About

The Baldy Mesa 2 project is a proposed 125 MW hybrid solar and battery energy storage project located in San Bernardino County, California. The development project consists of a 50 MW solar array coupled with a 75 MW battery energy storage system. It is interconnected to the Southern California Edison (SCE) grid at the Roadway Substation 115kV.

The project is listed in the CAISO interconnection queue under queue ID CAISO-1519, with an initial queue entry date of April 16, 2018. The proposed commercial operation date is November 1, 2026. An Interconnection Agreement (IA) for the project has been executed as of November 4, 2020.
