Sumita Tono wind project under way

16 May 2023

Pattern Energy Group LP and its affiliate in Japan, Green Power Investment Corp, have completed construction and begun operation at the 113 MW Sumita Tono wind facility, in the mountainous area between the municipalities of Tono and Sumita in Iwate Prefecture.

Sumita Tono is described as a best-in-class facility that is now harnessing the strong westerly winds available in the Kitakami mountains. It is Pattern and GPI's fourth development project in Japan and expect to develop more sources of clean power throughout the country.

Sumita Tono Wind utilises 27 Vestas 4.2 MW wind turbines. The project has a 20-year feed-in-tariff power purchase agreement with Tohoku Electric Power Network for 100% of the power output. GPI and its affiliates will be responsible for the long-term operation and maintenance of the facility with Vestas providing wind turbine maintenance.

Including Sumita Tono Wind, Pattern now has eight renewable energy facilities in Japan either operating or under construction, including four onshore wind power facilities and two solar power facilities in operation, and one offshore and one onshore wind power facility under construction.
