Invenergy-affiliated Hakodate-Torasawa Wind LLC submitted the environmental impact assessment methodology for its up to 47.3MW Hakodate-Torasawa onshore wind project in Hakodate City, Hokkaido.
According to the document made available for public viewing on April 10, 2026, the company plans to install up to 11 4.3MW turbines across a 1,119ha site. It targets beginning construction in April 2031, with commercial operations starting in January 2035.
Other projects undergoing environmental impact assessment in the area include Community Wind Power’s 20MW Kijihi-Kiyama, which has not advanced from the methodology stage since 2012, JR-EAST Energy Development’s up to Niyama-Kogen, also in the methodology stage since April 2024, and Eurus Energy Holdings’s up to 160MW Toi, which submitted a primary consideration in July 2022.
The methodology is the first full environmental impact assessment-related document Hakodate-Torasawa has submitted. As a Class 2 onshore wind power plant with capacity between 37.5MW and 50MW, Hakodate-Torasawa was exempt from submitting a primary consideration that marks the beginning of the process for larger projects.
Invenergy’s portfolio in Japan includes the 63MW Rusutsu Wind Power Plant in Hokkaido operating under a PPA with Honda and a pair of onshore wind farms totaling 214.2MW under construction.
