The BALDY MESA project is a proposed 225 MW hybrid solar and battery energy storage project located in San Bernardino County, California. The development project consists of a 150 MW solar array coupled with a 75 MW battery energy storage system. Interconnection is being pursued through the CAISO queue (queue ID CAISO-1413) with Southern California Edison (SCE) as the utility. The project entered the queue on May 1, 2017, and has a proposed commercial operation date of November 1, 2026.
The project's interconnection agreement (IA) was executed on November 9, 2020. The point of interconnection (POI) is the Roadway Substation 115kV bus. The BALDY MESA project has been the subject of recent news coverage, with 16 articles appearing in industry and deals publications.
