Japan’s renewable energy ambitions just gained more wind in their sails. On October 1, 2025, JERA, through its renewable energy arm JERA Nex Limited, announced the sale of a stake in the Ishikari Bay New Port offshore wind farm and battery project to Hokkaido Electric Power Company and Tohoku Electric Power. While the transaction value remains undisclosed, the deal signals a major stride in collaboration and long-term energy sustainability for Japan.

The Ishikari Bay New Port project, once primarily driven by JERA and Green Power Investment Corporation (GPI), now welcomes two new influential partners — Hokkaido Electric and Tohoku Electric. Their participation marks a new chapter of collaboration among four energy leaders with proven track records in generation and community engagement. This partnership structure, through the newly formed investment vehicle, reinforces the stability and operational efficiency of the project. For Hokkaido Electric, whose roots run deep in the region, and Tohoku Electric, with more than 70 years of expertise, the synergy offers immense potential for both regional and national renewable growth.

Situated in Hokkaido, the Ishikari Bay New Port offshore wind farm stands as one of Japan’s pioneering examples of renewable innovation. Featuring 14 Siemens Gamesa turbines, each generating 8 MW for a total capacity of 112 MW, the project also integrates a state-of-the-art 100 MW/180 MWh battery storage system. Commercial operations commenced in January 2024, and the power generated is sold under a 20-year feed-in-tariff (FIT) agreement at 36 yen per kWh ($243.08/MWh) to Hokkaido Electric Power Network Co., Inc. This combination of wind and battery technology underscores Japan’s commitment to ensuring a stable, efficient, and sustainable power supply.

Beyond clean power generation, the Ishikari Bay partnership is a model of regional empowerment and sustainable growth. With local utility engagement, the project ensures that benefits — from employment opportunities to stable energy access — directly support communities in Hokkaido and northern Japan. The move aligns seamlessly with JERA’s broader strategy of integrating JERA Nex into JERA Nex bp, its UK-based offshore wind joint venture with bp, expanding its global renewable footprint. As Japan targets carbon neutrality by 2050, such strategic collaborations will be vital to driving renewable adoption and energy innovation across Asia.

The Ishikari Bay transaction reflects more than a shift in ownership — it’s a testament to the growing momentum of Japan’s offshore wind revolution. By combining global expertise and local stewardship, JERA and its partners are propelling Japan toward a cleaner, more resilient energy future.
