Kyushu Electric Power and NGK Insulators have delivered the battery energy storage project.

Additional information

The facility offers energy-storage capabilities similar to those of pumped hydro facilities while helping to improve the balance of supply and demand when renewable energy sources are used. The energy storage system achieves effective overall control and improved operational efficiency through the use of Mitsubishi Electric’s BLEnDer RE battery SCADA system to monitor and control modules in a multiple module system. Also, containerized, compact (double stacked) battery modules help to reduce the facility footprint, installation time and construction costs.
