World’s largest offshore windfarm set to power UK this week

3122071 offshorewins

The Hornsea One windfarm off the Yorkshire coast is set to supply its first power the UK electricity grid this week.

Danish developer Ørsted has installed 174 turbines at Hornsea One, which will become the world’s largest offshore windfarm, covering 407km² when it is complete.

The 1.2GW capacity windfarm will supply 1M homes, making it twice as powerful as any existing windfarm.

The first two phases will use 7MW turbines. The latter stages will have 10MW turbines.

The power station is the first of four planned for the area, with a green light and subsidies already awarded to a second stage, due for completion in the early 2020s.

Ørsted UK managing director Matthew Wright said: “The ability to generate clean electricity offshore at this scale is a globally significant milestone at a time when urgent action needs to be taken to tackle climate change.”

The turbines for Hornsea One are built and shipped from Siemens Gamesa’s factory in Hull. Around half of the project’s transition elements, the yellow connection between the foundation and the tower, are made on Teesside. Many of the towers themselves are made in Campbeltown in the Scottish highlands.

  • How are the towers transported from Campbeltown? It's difficult to imagine a coastal site in the UK that's more remote from Hornsea!

  • Well done to Danish developer Ørsted in putting this together. I hope one day Dogger Bank will dwarf this one!
    Shame we had no capital cost associated with this. Curious as to how it compares to the program and costs of Hinckley C.
