NTT Anode Energy’s operational grid-scale battery storage portfolio grew to 10 assets in March 2026 with the commissioning of the 2MW/8.23MWh Kagawa Kanonji and the 2MW/9.99MWh Fukuoka Moji projects, the company announced on April 1, 2026.
Both facilities are aggregated in-house by NTT Anode Energy. The project in Kanonji City, Kagawa Prefecture, uses PowerX battery systems. The company did not disclose the equipment supplier for the Moji asset in Kitakyushu City, Fukuoka Prefecture.
In total, NTT Anode Energy has 18.52MW/81.45MWh of operational capacity consisting exclusively of high-voltage facilities. By FY2028, it plans to build 13 more assets, including 11 high-voltage and two extra high-voltage. Four of its projects were awarded METI’s subsidy for promoting grid-scale battery storage and three were selected for a similar scheme offered by the Tokyo Metropolitan Government.
The company commissioned its first grid-scale battery storage project, a 1.4MW/4.2MWh asset in Fukuoka Prefecture developed jointly with Mitsubishi Corporation and Kyushu Electric Power, in July 2023. It is now building its first extra high-voltage facility, the 18.2MW/76.8MWh Hokkaido Tomakomai Power Storage Station, which is expected to come online in FY2028.
Separately from standalone assets, NTT Anode Energy also completed its first two battery storage retrofit projects of existing solar power plants in February 2026.
