PowerX has announced plans to establish a manufacturing facility, Power Base Hokkaido, in Hokkaido, Japan to expand production of grid-scale battery energy storage systems (BESS). The facility will manufacture the Mega Power 2500, a containerised large-scale BESS, with an annual production capacity of 800 units, equivalent to around 2 GWh. The company has finalised agreements for acquiring the land and building for the project. The total investment for the project is estimated at JPY 3.0 billion.
The facility will cater to battery storage demand in the Hokkaido and Tohoku regions, with manufacturing operations scheduled to commence in June 2027. It will initially operate with one production line, with provisions to expand to two lines. The project involves renovating an existing structure at the site. The project site is located near the Port of Tomakomai and New Chitose Airport, providing access to both maritime and air transport. Currently, all manufacturing operations are based in Tamano City, Okayama Prefecture, where it produces large-scale BESS for grid and solar applications.
In March 2026, HD Renewable Energy secured approximately JPY 5.4 billion in project financing for its Helios 50 MW grid-scale BESS project located in Hokkaido, Japan. The financing was raised through a green project bond supported by Nomura Capital Investment and Nomura Securities. The project has a capacity of 50 MW and actively participates in electricity trading.
