Nexans announced Monday it has secured a contract to supply of over 200 kilometers of the high voltage alternating current (HVAC) subsea export cable system for the near shore section of the world's largest offshore wind farm. The contract, from Danish developer Ørsted, is worth more than 150 million euros.
Located in the North Sea, approximately 89 kilometers from the Yorkshire coast, the 1.4 GW Hornsea 2 is the sister project to Hornsea 1. Ørsted is now constructing the project, with completion set for 2022. Once Hornsea 2 begins operating, it will provide enough electricity to power more than 1.3 million homes.
The cables for Hornsea 2 project will be manufactured at Nexans Norway site in Halden.
The project will be equipped with Nexans three-core HVAC submarine cables in order to bring the electricity produced by the wind farm onshore. These 245 kV XLPE cables will be part of the near shore section of the export circuits linking the wind farm’s reactive power substation to the onshore substation. The circuits will comprise three individual near shore export cables and will follow a similar route to Hornsea 1, for which Nexans Norway has earlier supplied 139 kilometers of three-phase 36 kV subsea cable inter-linking a total of 58 wind turbines and connecting them to the offshore transformer station. The route will make landfall at Horseshoe Point from where land cables will feed the power to North Killingholme onshore substation.
