The battery system, which is expected to stabilize the flow of wind and solar power by using vanadium redox flow battery technology, will be installed at Hokkaido Electric Power’s Minami Hayakita substation, Sumitomo said.

According to the company, the battery system is a part of the three plans that have been announced by the Ministry of Economy, Trade and Industry in April 2013, as the island has been flooded with applications for large-size solar projects.
