The 315 MW order for the Oga Katagami Akita Offshore Wind Project in Akita Prefecture, Japan is being developed by Oga Katagami Akita Offshore Green Energy LLC., a consortium consisting of JERA Co., Inc., Electric Power Development Co., Ltd. (J-POWER), Tohoku Electric Power Co., Inc. (Tohoku EPCO), and ITOCHU Corp.
The order includes 21 V236-15.0 MW turbines as well as a long-term service agreement designed to ensure optimised performance of the assets.
The order is the first firm order in the Asia Pacific region for Vestas’ V236-15.0 MW turbine and the company’s first firm order for a project to be developed under the Japanese government's offshore wind auctions based on the Renewable Energy Sea Area Utilisation Act.
“We are honoured to partner with JERA, J-POWER, Tohoku EPCO, and ITOCHU on this landmark project for Asia Pacific’s offshore wind industry and provide them with our flagship offshore wind technology” said Purvin Patel, President of Vestas Asia Pacific. “This milestone reflects our ongoing commitment to advancing clean energy solutions and building the long-term future of the offshore wind market in the Asia Pacific region.”
The V236-15.0 MW received its type certification last year, ensuring safety and quality. Since its launch, Vestas has secured more than 6 GW of firm orders globally, proving the turbine variant’s competitiveness across offshore markets.
The project site is located off the coast of Oga city, Katagami city, and Akita city in Akita prefecture. Deliveries are expected to begin in 2026, while commissioning is planned in 2027. The wind farm is scheduled to begin operations in June 2028.
Meanwhile, in Spain, Iberdrola has placed a 99 MW order with Vestas for the repowering of the Molar de Molinar and Isabela wind farms, located in Castilla-La Mancha. The contracts include the supply and installation of 11 V150-4.5 MW wind turbines and 11 V136-4.5 MW wind turbines respectively, as well as a 10-year Active Output Management (AOM 4000) service agreement.
The 22 new wind turbines will replace 139 legacy models currently powering the sites, increasing their energy output by around 30 percent.
“Thanks to the grants awarded by the Spanish Institute for the Diversification and Saving of Energy (IDAE), through a competitive process, Iberdrola has been able to start these pioneering investments in repowering” said José González Bujanda, Head of Project Development at Iberdrola Renewable Energy. “The projects required to dismantle the old wind farms, and to adapt the foundations and electrical connections to host larger machines. The installation of more modern wind turbines will allow us to make better use of the wind resource, reducing the environmental impact.”
With over 9.9 GW of wind turbines turning 20 years old or more in 2025, Spain’s repowering market is expected to become a driving force of its energy transition in the coming years. Replacing legacy turbines with current technology also allows to considerably increase the onshore wind capacity with fewer turbines, reducing the environmental impact and the use of ground at the site.
Turbine delivery is expected by the second quarter of 2025 whilst commissioning is planned by the fourth quarter of 2025.
Once operational, both wind parks combined will now prevent 53,000 tonnes of CO2 from being emitted into the atmosphere per year. The project’s CO2 footprint will also benefit from Vestas’ strong presence in Spain. The company currently manufactures onshore blades in its factory in Daimiel by Ciudad Real. The wind turbine towers will also be manufactured locally.
Since 1991, when Vestas installed its first wind turbine in Spain, the company has accumulated over 5.3 GW of installed capacity in the country.
