SDG&E's Vanadium Redox Flow Microgrid Tour

Presented by Sumitomo Electric Industries and SDG&E

Intersolar North America and Energy Storage North America (ISNA/ESNA) invites you to take an exclusive tour of California’s first utility-scale Vanadium Redox Flow (VRF) battery and microgrid. 

In support of the state’s goals for 100% carbon-free electricity, grid reliability and climate resilience, San Diego Gas & Electric (SDG&E) and Sumitomo Electric Industries, Ltd. (Sumitomo Electric) undertook and successfully completed a zero-emissions microgrid pilot in December 2021 using a vanadium redox flow (VRF) battery – the first-of-its-kind to be connected to the state’s energy market in 2018. 

Different from lithium-ion batteries, the VRF battery is a proven and innovative energy storage system that is safe, non-flammable, flexible, and long-lasting. The electrolyte solution can be reused indefinitely. In fact, there are Sumitomo Electric VRF batteries in Japan that have been efficiently operating for more than 25 years. The demonstration project further shows that VRF batteries are an innovative technology that can be deployed to prevent blackouts caused by natural disasters, improve grid resiliency and integrate more clean, renewable energy into the grid.

The VRF microgrid demonstration is a joint partnership venture between Japan’s New Energy and Industrial Technology Development Organization (NEDO) and the California Governor’s Office of Business and Economic Development (GO-Biz) and was installed in 2017. 

Tour Date/Time: Tuesday, January 16, 2024 – 9:30AM – 12:00 PM PT

Location: Bonita, California
