PowerX to Open Hokkaido Factory to Boost Grid-Scale Battery Capacity

PowerX, Inc. ( (JP:485A) ) has issued an announcement.

PowerX, Inc. has approved the opening of a new factory, “Power Base Hokkaido,” in Tomakomai City, Hokkaido, to expand production of large-scale battery energy storage systems amid rising demand for grid stabilization. The facility, created by renovating an existing building near major sea and air hubs, is scheduled to start operations in June 2027 and will mainly serve grid-scale battery farm projects in Hokkaido and Tohoku.

The new plant will initially operate one production line, with capacity for up to two lines, and is designed to manufacture up to 800 units per year of its Mega Power 2500 container-type systems, equivalent to around 2 GWh. With a total project cost of 3 billion yen financed through internal funds and borrowings, the investment aims to increase supply capacity, diversify geographic risk, cut logistics costs, and support Hokkaido’s renewable energy expansion, with limited expected impact on near-term earnings.

PowerX is also considering producing its developing Scalable Modular Data Center on the same lines, indicating potential synergies between its energy storage and data infrastructure businesses. The company emphasizes collaboration with local partners to drive regional renewable energy deployment and contribute to Japan’s carbon-neutral goals, while noting that detailed plans and financing structures may evolve as design progresses.
