Sumitomo Electric Industries, Ltd. has completed a megawatt-class electric power generation/storage system on the premises of its Yokohama Works.

The system consists of 28 units of concentrated photovoltaic (maximum total power generation: 200 kW)* and a redox flow battery (capacity: 1 MW x 5 hours), which respectively function as renewable energy sources and a storage facility of electric power generated by the CPV units. Connected to external commercial power networks, the system can also store electricity provided by power companies during the night. This system employs an energy management system (EMS), which monitors the amount of CPV-generated electric power, battery storage and power consumption, and stores the measurement data in the central server.
