Promoting the grid-scale battery storage business to contribute to the stable supply of electricity

In July 2024, we launched our Group’s first initiative in the grid-scale battery storage business.This project aims to stabilize power supply and demand by installing a 25MW, 50MWh battery storage system in Chitose City, Hokkaido to conduct charging and discharging operations. Mitsubishi HC Capital Energy, Mitsubishi Estate, Samsung C&T, and Osaka Gas jointly invested in a special purpose company to begin construction in April 2025, with the aim of commencing operations in January 2027.
With the increasing deployment of renewable energy, whose output is inherently variable depending on weather conditions, the importance of energy storage systems that can stabilize the supply of electricity has grown significantly. Through our battery storage business, our Group will contribute to expanding renewable energy by enhancing stable operation of the power grid, and work to build a decarbonized society.
