The Los Esteros Critical Energy Facility Expansion is a proposed hybrid project located in Santa Clara County, California, with a total capacity of 123 MW. The project, which has appeared in recent news, consists of a 120 MW gas component and a 3 MW battery component. It is interconnected to the CAISO grid under queue ID CAISO-378 and is linked to an existing operating plant.
The project entered the CAISO interconnection queue on May 28, 2008, with a proposed commercial operation date of September 1, 2023. An Interconnection Agreement (IA) was executed on April 4, 2011. The project's point of interconnection (POI) is the Los Esteros 115 kV substation, and the interconnecting utility is PG&E.
