On March 1, 2025, Cosmo Eco Power commissioned the 27MW Shin Iwaya Wind Park in Higashidori Village, Aomori Prefecture, which was built the replace the decommissioned Iwaya Wind Park.
According to the company’s statement from March 3, 2025, the power plant is currently operating under the feed-in-tariff (FIT) scheme. It will be converted to the feed-in-premium (FIP) scheme, which requires generators to monetize their assets through commercial means, from April 1, 2025. While it is likely to be used for a corporate PPA, Cosmo Eco Power did not disclose its plans for the asset after the conversion.
The power plant consists of seven 4.3MW turbines with a combined output of 30.1MW operationally limited to 27MW. While Cosmo Eco Power was considering expanding the wind farm to as much as 69MW when it first started its environmental impact assessment in 2017, it scaled it down to the same 27MW as the original project in later in the process.
The original Iwaya Wind Park was commissioned in February 2003 and remained in operation until March 2023. It comprised of 18 1.5MW turbines.
Commissioning of the Shin Iwaya power plant brings Cosmo Eco Power’s onshore wind portfolio to a total of 19 assets with a combined output of over 300MW. The Japan Energy Hub PPA database shows that the company disclosed at four onshore wind corporate PPAs including a 33MW deal with Amazon and a virtual PPA with JR West.
Correction (March 7, 2025): The previous version of this article incorrectly referred to the PPAs mentioned in the last paragraph as being offshore wind.
