Japan Wind Development affiliate Atsumi Wind Development submitted the draft environmental impact assessment for its Tahara-Nakayama onshore wind project in Tahara City, Aichi Prefecture, to METI and other stakeholders.
According to the document released for public viewing on April 10, 2026, the company plans to install five turbines, 4.2MW each, across a 36.6ha site. Their combined output is expected to be capped at 18MW due to grid connection size. Groundbreaking is targeted for January 2028, with commercial operation following in March 2029.
Atsumi Wind Development launched the environmental impact assessment process in August 2019, planning an up to 19.2MW wind farm comprising up to six 3.2MW to 3.6MW turbines at the time. The project advanced to the methodology stage in January 2020 and had its turbine configuration revised in the latest draft assessment stage.
Several onshore wind assets already operate on Atsumi Peninsula, including a separate 10.5MW Japan Wind Development project commissioned in 2006, an 8MW Green Power Investment-affiliated project, and Chubu Electric Power’s 7.4MW Atsumi Wind Power Plant. The utility is currently building the 21MW Atsumi No. 2 Power Plant to expand the original facility’s capacity.
Japan Wind Development, founded in 1999, completed 37 wind power plants in the country totaling 605.49MW. It has multiple other projects, such as the 37.8MW Mutsu-Yokohama and the 46.2MW Tsukikoshigenya, under development. The company was acquired by Bain Capital in 2015 and sold to its current owner, Infroneer Holdings, in 2024.
