OVERNIGHT SOLAR is a proposed hybrid solar and battery project located in San Bernardino County, California, with a total capacity of 300 MW. The project consists of 150 MW of solar generation and a 150 MW battery energy storage system. It is listed in the CAISO interconnection queue as entry CAISO-1774, with a queue entry date of April 15, 2020, and a proposed commercial operation date of May 1, 2027. The project's point of interconnection is the Kramer Substation 230kV, and the interconnecting utility is Southern California Edison (SCE).
The project's interconnection agreement (IA) has been executed as of February 17, 2024. Recent news coverage indicates interest in the project, with nine articles appearing in industry publications.
