The Goto floating wind farm, Japan’s first commercial floating offshore wind installation, became fully operational on 5 January 2026, as announced by the consortium comprising Toda Corporation, ENEOS Renewable Energy Corporation, Osaka Gas, INPEX Corporation, Kansai Electric Power Co. (KEPCO), and Chubu Electric Power.
The 16.8 MW wind farm consists of eight Hitachi 2.1 MW turbines on hybrid SPAR-type floating foundations with a steel top and concrete bottom, engineered by Toda Corporation, which leads the consortium.
This is the world’s first commercial use of hybrid SPAR-type floater technology, according to project partners.
Construction began in October 2022, when the first foundation was moved from Fukue Port to the site offshore Kabashima.
The Goto Floating Wind Farm LLC consortium won Japan’s inaugural offshore wind auction following the Renewable Sea Area Utilization Law, effective April 2019. It is the first such facility certified by Japan’s Minister of Economy, Trade and Industry and the Minister of Land, Infrastructure, Transport and Tourism.
On 5 January, the consortium emphasized local company involvement in the project’s construction and noted their expected role in operations and maintenance (O&M).
“In support of local energy production for local consumption, the electricity generated will be supplied primarily to local retail electricity providers,” stated Goto Floating Wind Farm LLC.
Details released earlier indicate the wind farm will supply electricity at JPY 36 per kWh (EUR 0.20/kWh) until its planned end-of-life in December 2043.
