Everythings works fine so far at the construction site of Hornsea One 120 km off the Yorkshire Coast in the UK. Now, Ørsted A/S, one part of the 50/50 joint venture between Ørsted A/S and Global Infrastructure Partners, has announced the completion of export cable installation at Hornsea One months ahead of schedule.

With offshore export cables totalling 467km, around the same distance as London to Newcastle, plus an onshore cable route of 38km connecting each of the three strings to the national grid, it is the longest AC offshore wind export cable system ever to have been installed.

When the wind farm is up and running, it will be able to generate electricity for more than one million people. The electricity generated by the 174 Siemens 7MW turbines out at sea will then pass through one of three offshore substations, before being carried by three high voltage subsea export cables (245kV), via the reactive compensation station, to shore.

Duncan Clark, Programme Director for Hornsea Projects One and Two, said: “This record-breaking project is a step up in scale from the offshore wind farms we have today. It will be the first offshore wind farm in the world with a capacity over 1GW, and at 120km out to sea, we are pioneering new technology and really at the forefront of scaling up clean energy infrastructure with each phase we complete.
