About

The Menifee Power Bank is a proposed 680 MW battery storage project located in Riverside County, California. The project is interconnected to the CAISO grid under queue ID CAISO-1645. Its queue entry date was April 15, 2019, and the proposed commercial operation date is October 1, 2025. The interconnection agreement for the project was executed on December 14, 2021.

The development project is linked to the existing Menifee Power Bank operating plant (EIA plant ID 66494). The point of interconnection is the Valley Substation 500kV. The project has been the subject of recent news coverage.
