Eurus Energy Completes Repowering of 43-MW Kamaishi Wind Farm in Japan
Japanese renewable energy developer Eurus Energy Holdings Corporation has completed the repowering of its 42.9-MW Eurus Kamaishi wind farm in Iwate Prefecture, northern Japan.
The project involved replacing 43 legacy wind turbines rated at 1 MW each with 11 modern turbines rated at 4.2 MW apiece, supplied by Vestas Wind Systems A/S. Commercial operations were temporarily suspended in March 2023 to allow for the upgrade and officially resumed on March 1, 2026.
The wind farm, which has been in operation since December 2004, is located across the cities of Kamaishi, Tono and Otsuchi. Electricity generated at the site is sold to regional utility Tohoku Electric Power Co Inc.
Following the repowering, Eurus Energy expects the facility to generate enough electricity to meet the annual demand of approximately 24,000 average households. The company also estimates the upgraded wind farm will offset around 40,000 tonnes of carbon dioxide emissions per year.
Repowering projects are increasingly common in Japan’s maturing onshore wind sector, enabling operators to improve efficiency and output by installing fewer, higher-capacity turbines while utilising existing grid connections and infrastructure.
The Kamaishi upgrade reflects broader efforts to modernise early-generation wind assets as Japan works toward its long-term decarbonisation and renewable energy targets.
