About

The GWF TRACY project is a proposed hybrid development project located in San Joaquin County, California, within the CAISO region. The project, with a total capacity of 185 MW, consists of a 145 MW gas component and a 40 MW battery component.

The project is listed in the CAISO interconnection queue as entry CAISO-268, with an interconnection queue entry date of January 1, 1970. The proposed commercial operation date is April 28, 2027, and the Interconnection Agreement (IA) has been executed as of January 1, 1970. The project is interconnected to the PGAE utility grid at the Tesla-Manteca 115kV line via Schulte Switchyard.
