NKT has been awarded a supply contract for the delivery of the high-voltage DC on- and offshore export cable system to the Hornsea 3 project which is being developed by Ørsted.
The contract will comprise the design, manufacturing, jointing and termination of the export power cable system for Hornsea 3 which will include two circuits with a route length of approx.170 km 320 kV DC offshore cable, 50 km 320 kV DC onshore cable as well as four circuits for 1.5 km route of 400 kV AC onshore cable. The DC system will connect the wind turbines with the substation while the AC cables will connect the substation to the national grid. NKT will produce the power cables at the high-voltage factory in Karlskrona, Sweden, and plan to complete the project in 2027. Subject to Ørsted taking a final investment decision, Hornsea 3 will be located in the North Sea, approximately 160 km off the Yorkshire coast. When Hornsea 3 comes online the combined capacity of Hornsea 1, 2 and 3 will be in excess of 5 GW
