Startup of Goto City Offshore Wind in Japan Delayed Until 2026


Goto Floating Wind Farm LLC (Consortium) has decided to revise the initial project schedule of the Goto City Offshore Wind Power Generation Project (Project) due to the discovery of defects in a floating structure.

Several Japanese businesses, including the utilities Osaka Gas, Kansai Electric Power and Chubu Electric Power; renewable power developer Japan Renewable Energy; general contractor Toda and upstream firm Inpex make up the Consortium developing the 16.8 MW offshore wind farm.

Located in Goto City, part of the Nagasaki prefecture in southwest Japan, the wind power plant was scheduled to begin commercial operation in January 2024. However, the construction process has been delayed due to defects discovered in a floating structure during construction. Accordingly, the Consortium filed an application to revise the Project’s public occupancy plan rescheduling the Project’s operational startup for January 2026. The Ministry of Economy, Trade and Industry and the Ministry of Land, Infrastructure, Transport and Tourism approved the application on September 22, 2023.

Earlier this year, in May, defects were discovered in two floating structures under construction at an onshore yard. Toda subsequently confirmed the facts, investigated the causes and considered countermeasures. The company has also taken corrective measures for the defects in the two floating structures and restarted construction work at the onshore yard.

Additionally, Toda will conduct inspections of a floating structure already installed off the coast of Sakiyama to verify the existence of defects. One of the three floating structures installed off the coast of Sakiyama will be landed on the yard in Fukue Port where the integrity of the floating structure will be verified. Based on the results, Toda will decide whether to inspect the remaining two floating structures
