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.

A press release said that the order calls for the design, manufacturing, jointing and termination of the export power cable system for Hornsea 3. It will include two circuits with a route length of approximately 170 km of 320 kV DC offshore cable and 50 km of 320 kV DC onshore cable as well as four circuits for a 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. The final order has an estimated value of €500 million.

NKT notes that, last year, the company completed its role as supplier for Hornsea 2. 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, making it one of the world’s largest offshore wind zones and capable of covering the power consumption of approximately five million U.K. homes.

NKT will produce the power cables at its high-voltage factory in Karlskrona, Sweden. The project is scheduled to be completed in 2027.
