Consortium Led by Toda Corp. Launches Commercial Operations at Goto Floating Offshore Wind Farm

Goto Floating Wind Farm LLC, a special-purpose company (SPC) established by a consortium including Japanese construction company Toda Corporation, announced on January 5 the commencement of commercial operations at its floating offshore wind facility off the coast of Goto City, Nagasaki Prefecture.

The project utilizes a "hybrid spar" design, which employs steel for the upper portion of the floating structure and concrete for the lower section. The project has established a framework for the local production and consumption of renewable energy within Goto City. The initiative is drawing attention as a model for revitalizing regional economies through sustainable energy infrastructure.

The "Goto Offshore Wind Farm," Japan’s first commercial-scale floating offshore wind project, consists of eight turbines installed across a four-kilometer maritime zone approximately seven kilometers east of Fukue Island. The facility employs a vertical cylindrical floater that supports the turbine at its apex, functioning like a nautical buoy. Each unit has a generation capacity of 2.1 megawatts (MW), with the total length including the foundation and turbine reaching 176 meters.

The renewable power generated by the farm is supplied to local consumers through Floating Wind Aggregation Co., Ltd., a Goto-based entity funded by Toda Corp. and its partners. By utilizing the Feed-in Tariff (FIT) system alongside a "Specified Wholesale Supply" scheme—a framework allowing power generators to provide electricity to retail providers—the project has built a local production and consumption model for electricity directly used by local enterprises and facilities.
