The Daggett Solar 3 project is a proposed 521.88 MW hybrid solar and battery energy storage project located in San Bernardino County, California. The development project consists of a 313.88 MW solar component and a 208 MW battery energy storage component. The project is in the CAISO interconnection queue (queue ID CAISO-1314) with an interconnection queue entry date of May 2, 2016, and a proposed commercial operation date of August 6, 2023.
The project's interconnection agreement (IA) was executed on December 6, 2018. The point of interconnection is the Kramer Substation 230kV. Daggett Solar 3 has been the subject of recent news coverage, with seven articles appearing in industry, deals, and grid-related publications.
