Vena Energy-affiliated special purpose company (SPC) Kagoshima Koriyama Wind LLC completed the environmental impact assessment for a 30MW onshore wind project along the border of Kagoshima and Satsumasendai cities in Kagoshima Prefecture. It submitted the final assessment on October 3 and received METI approval on October 29, 2025.
According to the document released for public viewing on December 1, 2025, the company plans to install eight 4.3MW turbines with a combined capacity of 34.4MW and cap their output due to a grid connection limit. It aims to begin construction in May 2026 and commission the asset in March 2029.
METI data shows the project was certified under the feed-in-tariff (FIT) scheme in FY2019, when onshore wind projects were offered a 19 yen per kWh tariff for 20 years. It is unclear whether Vena Energy plans to operate the project at the fixed rate or switch it to the feed-in-premium (FIP) scheme and sell its output through a corporate PPA.
Vena Energy’s wind-focused unit Japan Wind Energy began the environmental impact assessment for the project in September 2019 and advanced it to the methodology stage in January 2020. It submitted a draft assessment report in December 2021.
The group currently has three operational onshore wind power plants in Japan including the 7.5MW Reihoku in Kumamoto Prefecture commissioned in June 2021, the 36MW Nakasato in Aomori Prefecture that was brought online in April 2022, and the most recent, 7.5MW Nakaura, which has been in service since May 2025. Prior to Kagoshima Koriyama, it completed the environmental impact assessment for a 50MW project in Shimane Prefecture that it plans to build by July 2028.
