Mitsubishi Electric has delivered the world's largest energy storage system to Kyushu Electric Power.

The system, which has 50MW output and 300MWh rated capacity, was deployed at the Buzen Substation in Buzen, Fukuoka Prefecture in Japan.

It is part of a project that seeks to balance the supply and demand ratio through high capacity energy storage systems.

The facility provides energy-storage capabilities, similar to pumped hydro facilities, and seeks to improve the supply-demand balance when renewable energy sources are put to use.

According to the company, the energy storage system aids in achieving overall control and improved operational efficiency with the use of Mitsubishi Electric’s BLEnDer RE battery SCADA system to monitor and control modules in a multiple module system.

Additionally, the battery modules which are containerized and compact are believed to lower the facility footprint, deployment time and construction costs.

BLEnDer RE is an energy-management system which regulates and controls energy storage within the SmartGrid’s power supply and demand system.

The system regularizes the variations in frequency and power flow caused by renewable generation through battery control.

It facilitates efficient operation through power supply control with synchronized use of multiple-generation sources and batteries, as well as technology for optimized operation, stoppage timing and output of the various sources.

Last November, Mitsubishi and partners formed a consortium to build a floating offshore wind farm project in Portugal by investing $130m. The consortium included Chiyoda, EDP Renewables, Repsol, and Engie.
