U.K.-based JDR Cable Systems (JDR) reports that it has won a multi-million pound contract to supply inter-array cables and termination work for Ørsted’s record-breaking, 1.4 GW offshore wind farm, Hornsea Project Two.
A press release said that, when operational in 2022, the wind farm will supply electricity to over 1.3 million homes, and surpass its sister project Hornsea One, as the world’s largest offshore wind farm. The contract calls for JDR, part of Poland’s TFKable Group, to supply 100 km of inter-array cables that will be assembled in JDR’s Hartlepool facility. The inter-array cables link the wind farm turbines together, and carry the power to an offshore substation, which converts it to a higher voltage for transmission to shore.
The project, the release said, is Ørsted’s first in the U.K. to use 66 kV for its array cables, having used 33kV for previous projects. Using cables with a higher voltage helps to reduce electrical losses during transmission.
“This contract builds on experience from previous projects including Race Bank offshore wind farm, which we opened earlier this year, and Hornsea Project One, currently in construction,” said Patrick Harnett, the procurement and construction director for the project. “As our wind farm projects have grown in size, and distance from shore, so too have the contracts we place within the supply chain. The technology we use is also changing as we innovate to build these projects at massively lower cost of electricity into the U.K.’s grid.”
JDR CEO Richard Turner said that, “Hornsea Project Two ... will be built at the lowest ever price seen in the U.K.”
