The Aratina Solar Center 2 is a proposed 400 MW hybrid solar and battery energy storage project located in Kern County, California. The development project consists of 200 MW of solar photovoltaic generation paired with a 200 MW battery energy storage system. The project is in the California Independent System Operator (CAISO) interconnection queue under queue ID CAISO-1604, with an initial queue entry date of April 15, 2019. The proposed commercial operation date is December 31, 2026.
The project has an executed interconnection agreement (IA), dated July 29, 2021. The point of interconnection is the Kramer Substation at 230kV, and the interconnecting utility is Southern California Edison (SCE). The Aratina Solar Center 2 project has been mentioned in recent news coverage.
