Overview
Located in Kikuchi City, Kumamoto Prefecture, the Kikuchi Battery Energy Storage System (BESS) is a utility-scale, grid-connected energy storage facility with an installed capacity of 2 MW / 8.36 MWh (4-hour duration). The project is designed to enhance grid reliability and flexibility by storing electricity during periods of lower demand and delivering power when it is needed most. By delivering balancing services, the facility contributes to the ongoing modernization and decarbonization of Japan's electricity sector.
