Initiating Redox Flow Batteries into the U.S. Wholesale Power Market
December 18, 2018
New Energy and Industrial Technology Development Organization
Sumitomo Electric Industries, Ltd.
The New Energy and Industrial Technology Development Organization (NEDO) and Sumitomo Electric Industries, Ltd. will connect a 2MW/8MWh stationary storage redox flow (RF) battery to the wholesale power market in California, USA. This demonstration is the first example of RF battery operation in the United States wholesale power market.
One important feature of the RF battery is that there are no restrictions on depth and number of charge/discharge cycles: one of many features making the RF battery suitable for long-lifetime large scale applications. The demonstration will examine techniques designed to enhance the economic value of RF batteries by providing frequency regulation and trade-based energy supply, which are central demands of the wholesale power market.
