NTT Anode Energy commissioned the 1.99MW/8.23MWh Fukuoka Wakamatsu Power Storage Station on April 3, 2025.
The grid-scale storage facility in Kitakyushu City, Fukuoka Prefecture, is aggregated by NTT Anode Energy and used for trading in the wholesale, balancing, and capacity markets.
Seibu Denki, a communication infrastructure construction company with a longstanding relationship with NTT, was in charge of engineering, procurement, and construction (EPC). Fukuoka Wakamatsu Power Storage Station was its first storage project. Power X provided three 2.74MWh Mega Power containerized units, marking the first time the growing battery manufacturer supplied its systems to NTT Anode Energy.
“Going forward, each [of the three companies] will continue to contribute to the further spread of renewable energy,” NTT Anode Energy said in a statement.
Fukuoka Wakamatsu Power Storage Station follows NTT Anode Energy’s first operational grid-scale BESS project, the 1.4MW/4.2MWh Tagawa Power Storage Station in Fukuoka Prefecture, built jointly with Kyushu Electric Power and Mitsubishi Corporation. The NTT subsidiary is also developing multiple other projects including three supported by METI’s grid-scale storage subsidy and three that won Tokyo Metropolitan Government’s grid-scale storage subsidy.
