The world’s largest planned offshore wind farm is going to make use of the world’s largest installed offshore wind turbines. The Dogger Bank Wind Farm in the North Sea off the Yorkshire coast of England will ultimately generate electricity for more than 4.5 million homes in the United Kingdom.
The 3.6 GW project will cost $10 billion and will be developed in three phases, the first two of which will use 13-MW wind turbines built by General Electric. The turbine’s blades measure 351 feet – longer than a soccer field. The turbines stand more than 850 feet tall, which is five times the size of the Arc de Triomphe. GE claims that a single rotation of one of these huge turbines can supply enough electricity to power the average British household for two days. When the project is completed in 2026, it will generate 5% of the United Kingdom’s electricity.
The previous version of GE’s Haliade-X turbines, rated at 12 MW, were ordered by the energy company Orsted for installation in two forthcoming U.S. windfarm: the Skipjack Farm off the coast of Maryland, and the Ocean Wind farm off the coast of New Jersey. The new version will be the largest turbines to reach operation in a commercial project. Meanwhile, Siemens Gamesa has a 14 MW turbine under development.
The order for 190 of the 13 MW giant turbines for the Dogger Bank farm arrived at GE on the same day that the company announced that it will no longer supply power equipment to new coal plants. Work on the Dogger Bank project started in January in an area of the North Sea that was previously dominated by oil and gas development.
