ENEOS Renewable Energy submitted a draft environmental impact assessment for the up to 79.8MW Imakane Setana onshore wind project in Hokkaido on September 9, 2025.
According to the document, the project is expected to consist of 19 4.2MW turbines spread across an approximately 1,783ha site on the border of Imakane and Setana towns. ENEOS Renewable Energy plans to begin construction in May 2028 and complete the project in February 2032, targeting March 2032 COD.
The project was originally developed by Japan Renewable Energy, which launched the environmental impact assessment process in August 2023 before its integration into ENEOS. At the time, the company was planning an up to 129MW wind farm. The scale was reduced to 103.2MW in the methodology stage, reached in February 2024, before further downsizing.
Operational wind power plants in the area include the 50MW Setana Osato commissioned in 2020 and the 12MW Setana Seaside commissioned in 2005, both affiliated with J-POWER.
Multiple larger projects in the area, such as ENEOS Renewable Energy’s up to 64.5MW Hokkaido Yakumo Town, Invenergy’s up to 195.2MW Setana Matsuoka, and Penta Ocean Construction’s up to 86MW Setana Futoro, are currently undergoing environmental impact assessment. Separately, the area off the coast of Setana Town is part of the Hiyama offshore wind development zone expected to be auctioned in the near future.
ENEOS Renewable Energy’s operational onshore wind power plant portfolio currently consists of 13 projects with a combined capacity of 237.5MW.
