On January 24, 2025, the Invenergy-affiliated Inaniwa Wind LLC released the environmental impact assessment report for the up to 134.4MW “Inaniwa Wind Power Plant” it is developing in Iwate Prefecture for public viewing.

According to the report, the project will consist of 32 turbines, each with an output of up to 4.2MW, spread across a 695ha area in Ninohe City and Hachimantai City. The turbines themselves will occupy approximately 45.5ha of the total project area. Invenergy plans to begin construction work on the Tohoku TSO area project in April 2025. Trial operations are expected to start in December 2027, followed by April 2028 COD.

The project’s environmental impact assessment process began in 2015 when Invenergy submitted a “planning-stage document on primary environmental impact consideration.” Inaniwa Wind submitted the environmental impact assessment report to the government on November 22, 2024, and on December 18, 2024, received a confirmation from METI that no revision will be required.

While the company separately initiated the environmental impact assessment process for an an up to 219.6MW “Ichinohe-Inaniwa” onshore wind project, the project has been at the first, “planning-stage document on primary environmental impact consideration” stage since May 2022. More recently, on January 10, 2025, Invenergy’s Shimamaki Wind LLC initiated the process for an up to 140MW onshore wind project in Hokkaido.
