The first turbine at the Dogger Bank wind farm in the U.K. North Sea has produced power, bringing electricity to British homes, Equinor said Oct. 10.

The wind farm, jointly developed in three phases by Equinor, SSE Renewables and Vårgrønn, will be largest in the world at 3.6 gigawatts with 277 wind turbines, Equinor said in a news release. Once complete, the wind farm will be capable of producing enough electricity to power the equivalent of 6 million British homes annually.

Full commercial operations are expected to begin in 2026.

“A renewable mega-project like Dogger Bank constitutes an industrial wind hub in the heart of the North Sea, playing a major role in the U.K.’s ambitions for offshore wind and supporting its net zero ambitions,” Equinor CEO Anders Opedal said in the release. “First power from Dogger Bank is a testament to the collaboration between the authorities, the project partners, suppliers and our host communities to realize this project.”

Power is  transmitted from the wind farm to the U.K.’s national grid via the Dogger Bank’s high-voltage direct current (HVDC) transmission system. It’s the first time HVDC technology has been used on a U.K. wind farm, according to Equinor.

The milestone also marked the first time that one of GE Vernova’s Haliade-X 13-megawatt turbines have been used offshore.

“Each rotation of the 107-m long blades can produce enough energy to power an average British home for two days,” the company said in the release.

SSE Renewables is the lead operator for the project’s development and construction phase, while Equinor will serve as lead operator of the wind farm throughout its expected 35-year operational life, the release stated.
