Nozomi Energy and its affiliate Kuma Wind Power Generation submitted a draft environmental impact assessment for an up to 55.9MW onshore wind project in Kumamoto Prefecture on July 23, 2025.
According to the document, the project is expected to consist of 13 4.3MW turbines spread across an approximately 300ha site in Kuma Town. Nozomi Energy plans to begin construction in August 2026 and complete the project in November 2028, targetting December 2028 COD.
When beginning the environmental impact assessment process in May 2020, the original developer Hergo Japan Energy planned a 71.4MW power plant. It downsized the project to 61.2MW in a methodology document filed in January 2021. In 2023, the company secured a 15.9 yen per kWh feed-in-tariff (FIT) for 30MW of onshore wind in Kuma Town, potentially a portion of the project, in Japan’s second onshore wind auction.
Multiple other projects in the vicinity are currently undergoing environmental assessment, including GPSS-affiliated Japan Wind Power Service’s up to 60MW Izumi Wind Farm, ENEOS Renewable Energy’s up to 68.8MW Hisatsu, and J-POWER’s up to 129MW Hisatsu Wind Farm.
Nozomi Energy was launched in 2023 by Actis. In the same year, it acquired Hergo Japan Energy from Italy-based Infrastrutture, including its 230MW pipeline of operational and late-stage development solar and onshore wind projects, such as Kuma. According to Nozomi Energy’s website, the company is also developing a 56MW onshore wind project in Fukushima Prefecture.
The $500 million platform targets a 1.1GW portfolio of renewables and storage by 2027. It currently has over 500MW of operational capacity, secured mainly through acquisitions of operational FIT solar plants from PAG Renewables and Banpu affiliates.
