The Baylands Battery project is a proposed 250 MW battery storage project located in San Mateo County, California. The project is interconnected to the CAISO grid under queue ID CAISO-1900, with Pacific Gas & Electric (PGAE) as the utility. The project entered the interconnection queue on April 15, 2021, and has a proposed commercial operation date of March 24, 2030. Its interconnection status is currently in the System Impact Study phase.
The Baylands Battery project is being tracked due to its appearance in recent industry news.
