The Tanager Storage project is a proposed 200 MW battery energy storage system located in Santa Clara County, California. The project is in the California Independent System Operator (CAISO) interconnection queue as queue ID CAISO-1550. Its queue entry date was April 15, 2019, and the proposed commercial operation date is December 15, 2027.
The project's Interconnection Agreement (IA) was executed on December 22, 2021. The designated utility is Pacific Gas and Electric (PGAE), and the point of interconnection (POI) is the Los Esteros 230 kV substation. The project is currently listed as active in the CAISO queue.
