6 FAQs about 2MWH communication base station flow battery in San Diego

Can vanadium redox flow battery storage improve grid management?

Sumitomo and SDG&E's 2MW/8MWh redox flow battery system. Credit Sumitomo Utility San Diego Gas and Electric (SDG&E) and Sumitomo Electric (SEI) have launched a 2MW/8MWh pilot vanadium redox flow battery storage project in California to study how the technology can reliably integrate renewable energy and improve flexibility in grid management.

Does Sumitomo Electric have a vanadium redox flow battery?

Sumitomo Electric has been proceeding with a vanadium redox flow battery (VRFB) pilot project in coordination with San Diego Gas & Electric, stemming from a partnership between Japan's New Energy and Industrial Technology Development Organization (NEDO) and the California Governor's Office of Business and Economic Development (GO-Biz).

Does Sumitomo have a 99% redox flow battery?

Sumitomo says that its 2MW/8MWh vanadium redox flow battery achieved a 99% operating rate at San Diego Gas & Electric's (SDG&E) facility in California. The battery is expected to retain a capacity rate of 90% or more for 20 years in the electricity market.

How does a Sumitomo battery work?

The battery operates within a microgrid, supplying power to 66 residential and commercial customers for approximately five hours. Sumitomo and SDG&E set up a microgrid by integrating the battery into an electrical distribution network.
