The first turbine to be completed in a project to build the world’s largest offshore windfarm, in the North Sea, has begun powering British homes and businesses.

Developers confirmed on Monday that Dogger Bank, which sits 70 nautical miles off the coast of Yorkshire, started producing power over the weekend as the first of 277 turbines was connected to the electricity grid.

 

The project, jointly developed by Britain’s SSE and Norway’s Equinor and Vårgrønn, will produce 3.6 gigawatts of power, enough for 6m homes, when it is completed in 2026.

Rishi Sunak said the project was “critical to generating renewable, efficient energy that can power British homes from British seas”.

The prime minister’s endorsement comes weeks after he drew heavy criticism from green campaigners for rowing back on net zero policies as he seeks to make the energy transition a key political battleground.
