The DAYLIGHT project is a proposed 610.71 MW hybrid solar and battery energy storage project located in Kings County, California. The development project consists of 310.71 MW of solar photovoltaic generation coupled with a 300 MW battery energy storage system. The project is interconnected within the CAISO region and is in the CAISO interconnection queue as queue ID CAISO-1223, with an initial queue entry date of May 2, 2016. The proposed commercial operation date is January 19, 2028.
The interconnection agreement (IA) for the DAYLIGHT project has been executed as of December 18, 2023. The point of interconnection (POI) is the Mustang 230 kV substation. The project has been the subject of recent news coverage, with five articles categorized as industry-related and regulatory.
