The 60MWh vanadium flow battery system was installed in Minami-Hayakita substation of Hokkaido Electric Power Co., Inc. (HEPCO), and started operation December 2015, to demonstrate application of the storage battery as a dispatchable power source like fire plants and hydro plants. In commissioning tests, initial characteristics of the flow battery system, such as energy capacity, system efficiency, and response time, are confirmed. These results satisfied the specification of the system. This system has been operated to demonstrate various types of control modes such as load frequency control, compensation for wind power and PV output fluctuation, control for countermeasure against over generation, and so on. In periodic evaluation, it is confirmed that there is no deterioration of energy capacity and system efficiency, which are main performance parameters, for these 2 years of operation.
