Vestas has secured an order for the 113MW Sumita Tono Wind Farm in Japan with Green Power Sumita Tono GK.
With the site located in complex mountainous terrain in the Iwate prefecture, Vestas says the order demonstrates how its can leverage its industry-leading siting, project management and technology capabilities to deliver site-specific solutions in all conditions.
The turbine firm has developed a customised tower solution for the project to accommodate the site’s challenging transport, wind and seismic load conditions.
This will feature the tallest hub heights for any wind turbines above 4MW rating in the country, unlocking new wind resources at higher and more consistent wind speeds.
Developed by Green Power Investment Corporation (GPI), the order will include supply and supervision of installation of 27 Vestas V117-4.2MW turbines of which 23 will be installed on 114-metre towers and the other four on 94-metre towers.
It will be the first collaboration between Vestas and GPI, which is the Japanese partner of US based Pattern Energy Group LP that since 2004 has been focused on developing, constructing, and operating renewable projects in Japan.
Vestas Asia Pacific president and chief executive Purvin Patel said: “We are pleased to partner with GPI with this landmark order in Japan.
“With this order, we remain committed to contribute to Japan’s net zero goal and it also demonstrates our capabilities to tailor the best solution for our customers.”
GPI president Mitsuru Sakaki added: “It is through the continued support and teamwork of various stakeholders and local government that the project was able to reach commencement of construction; a process in which Vestas played a vital role.
“We would like to thank Vestas for this cooperation, on a particularly challenging project, and look forward to further long term collaboration to continue to push the Japanese wind industry to greater levels of efficiency and optimisation as we work to bring Japan’s sustainable energy targets closer.”
Vestas will also deliver a multi-year Active Output Management 5000 (AOM 5000) service agreement for the wind farm, providing an energy-based availability guarantee to ensure optimised performance and long-term business case certainty for the customer.
Delivery of the turbines will begin in the first quarter of 2022, with commissioning scheduled for the fourth quarter of 2022.
