Construction work for a huge offshore wind farm in the North Sea is underway.

In an announcement Friday, energy firm SSE said that onshore work for the 3.6 gigawatt (GW) Dogger Bank Wind Farms project had begun near Ulrome, a coastal village in the East Riding of Yorkshire, England.

Dogger Bank Wind Farms – which SSE described as "the world's largest offshore wind farm" – will be made up of three 1.2 GW offshore sites: Creyke Beck A, Creyke Beck B and Teesside A. The project is a joint venture between SSE Renewables and Norwegian energy major Equinor.

The construction work is being carried out by Jones Bros Civil Engineering U.K., a firm headquartered in North Wales.

The scheme is set to use GE's Haliade-X wind turbine, which has a 12 megawatt generator and stands 260 meters tall. According to SSE, the project will have the capability to produce enough renewable energy for more than 4.5 million homes per year.
