Hornsea 3

Delivering green power to more than 3 million UK homes 

Hornsea Three Offshore Wind Farm

About the project

Hornsea 3, with a capacity of 2.9 GW, will be the world’s single largest offshore wind farm upon completion. An £8. 5 billion infrastructure project, Hornsea 3 will make a significant contribution toward UK energy security, as well the local and national economy through supply chain investment and jobs. Learn about how we are working with local communities to ensure we deliver this project as collaboratively and efficiently as possible.

Top five questions answered

  • What’s going on in Oulton and Swardeston?

    We’ve begun to build the onshore part of Hornsea 3.  We are currently laying the cables that will bring the energy generated offshore by Hornsea 3 and connect it to our onshore electricity substation. From there, the energy will be connected to the National Grid so it can be distributed to millions of homes across the UK. So far, we’ve laid about 6 km of cable  out of a total of 51 km, so we’re still in the early stages.

    We’ve also been doing some work on our onshore substation near Swardeston, including landscaping. The next stage of the journey (in April) will be preparing the area where the cables will come onshore at Weybourne beach.

  • Why do such large lorries have to go along such small roads?

    As this is such a large national infrastructure project, traffic and deliveries to and from the sites are unavoidable. But we’ve been working closely with local authorities and residents to give advance notice of works taking place to help minimise disruption.

  • Why are you digging up the countryside?

    We’re laying the cabling that will bring energy onshore from our offshore wind farm once it’s built. We have agreements in place with landowners on how and where we work. Once cables have been laid, we’ll make good all construction sites and carefully restore the land to how it was before.

  • How will local residents benefit from this project?

    Norfolk is becoming a key hub for green energy, which will bring long-term investment and jobs to the region. We’ve also just launched our Hornsea 3  Community Benefit Fund which commits £7 million (£700,000 every year for the next ten years) to projects developed by, and for the benefit of, the local community in the North Norfolk and East Anglia region. We are committed to making a positive impact in the communities where we construct and operate our offshore wind farms.
