March 3, 2025
Cosmo Energy Holdings Co., Ltd.
Cosmo Eco Power Co., Ltd.
Cosmo Energy Group company Cosmo Eco Power Co., Ltd. announced that Shin-Iwaya Wind Park (hereafter, “the Power Plant”), which it has been rebuilding since April 2023, commenced commercial operations under Japan’s FIT scheme,1 starting on March 1, 2025.
The Power Plant operated commercially as Iwaya Wind Park for 20 years, from February 2003 to March 2023, but was temporarily shut down in order to undergo reconstruction work. Thanks to newfound support from the local community, landowners, and Higashidori Village in Shimokita District, Aomori Prefecture, reconstruction work has been completed, and the Power Plant has resumed commercial operations as Shin-Iwaya Wind Park with newly installed wind power generation facilities. Furthermore, the Power Plant will transition to operations under the FIP scheme2 from April 1, 2025, with a planned commercial operation period of 20 years.
The Power Plant is situated in a nature-rich environment, surrounded by the sea and mountains, and its stable year-round winds make it one of Japan’s most suitable locations for wind power generation. On clear days, the site offers breathtaking views that extend all the way to Hokkaido.
Through this business, Cosmo Eco Power will continue to pursue various initiatives in collaboration with the local community, all while considering regional development and staying true to its corporate mission: “We will promote a lasting, eco-friendly society by contributing to the spread of renewable energy.”

1. Feed-in Tariff (FIT) scheme: A program established in 2012 to promote the adoption of renewable energy. Under this scheme, the Japanese government guarantees that electric power companies can purchase electricity generated from renewable energy sources at a fixed price for a certain period. A portion of the electricity purchase cost is covered by the public through a renewable energy surcharge.
2. Feed-in Premium (FIP) scheme: A program established in April 2022 to further promote renewable energy adoption and establish it as a main power source. Under this scheme, power producers receive a premium on top of the revenue earned from selling electricity. Unlike the conventional FIT scheme, where electricity generated at power plants is purchased by electric power companies, the FIP scheme allows power producers to choose their buyers, including sales to the wholesale electricity market or direct transactions with consumers via corporate PPAs, etc.
