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.
This marks Vestas’ first firm order for its V236-15.0 MW turbine in the Asia-Pacific region, as well as 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 Utilization Act.
Since the launch of the 15 MW turbine in 2021, Vestas has secured more than 6 GW of firm orders globally, according to the firm.
The 315 MW Oga Katagami Akita Offshore Wind Project is being developed by Oga Katagami Akita Offshore Green Energy, a consortium consisting of JERA, Electric Power Development (J-POWER), Tohoku Electric Power (Tohoku EPCO), and ITOCHU.
The project site is located off the coast of Oga City, Akita City, and Katagami City in Akita Prefecture.
Deliveries are expected to begin in 2026, while commissioning is planned for the following year, Vestas said. The offshore wind farm is scheduled to commence operations in June 2028.
