The COBALT project is a proposed 512.61 MW hybrid solar and battery energy storage project located in Riverside County, California. The development project consists of a 256.41 MW solar array coupled with a 256.2 MW battery energy storage system. The project is in the CAISO interconnection queue (CAISO-1757) as of April 15, 2020, with a proposed commercial operation date of May 31, 2027. The point of interconnection is the Colorado River Substation at 220kV, and the interconnecting utility is SCE.
The project has an Interconnection Agreement (IA) executed as of May 1, 2023. The COBALT project has been the subject of recent news coverage, with 12 articles published related to deals, industry trends, development updates, regulatory matters, and grid implications.
