Wind Energy – HVDC Cable Systems
TenneT has awarded NKT, Nexans and a consortium of Jan De Nul, LS Cable and Denys to install 525 kV HVDC cable systems for ten projects.
The total volume of the contracts for the production and installation of the ten cable systems amounts to approximately € 5.5 billion.
With this agreement, TenneT completes the process of the large-scale tender cable launched in November 2022 for grid connection systems dedicated to a total of fourteen offshore and one onshore corridor project.
NKT will realise the connections for Nederwiek 3, landing onshore at either Geertruidenberg or Moerdijk and the connections for Doordewind 1 and Doordewind 2, landing at Eemshaven.

The consortium of Jan De Nul, LS Cable and Denys will realize the cable connections in Lower Saxony, to BalWin4 and LanWin1, both to be connected in Unterweser area, and LanWin5 in the Rastede area. This consortium has also been awarded the contract for the TenneT part of the onshore 525 kV DC corridor NordOstLink in Schleswig-Holstein Germany, a partner project with 50Hertz.
The scope of work of the contracts includes cable design, engineering, production, delivery, project management, onshore-, offshore- and nearshore installation of 525 kV HVDC cables and all jointing works in submarine and on land sections. The selected parties expect to start activities in the course of 2023.
The expected start for onshore cable laying activities will be after 2025. For offshore the cable laying activities will be in 2026. All 2 GW offshore projects are expected to be operational by 2031. The NordOstLink project is expected to be operational in 2032.
