The contracts awarded to NKT and Prysmian Power Link part of Prysmian Group have a volume of 4.6 billion euro.
The award covers 525-kV cable systems with a capacity of 2 GW per system for line construction projects that are legally enshrined in the Bundesbedarfsplan or envisaged in the draft of the Netzentwicklungsplan 2037/2045 (2023).
NKT with headquarter in Denmark is responsible for five of seven projects with a volume of 3.5 billion euros. In the Baltic Sea NKT is to supply the cables for the offshore grid connection systems of the Ost-2-4 area (Ostwind 4) off the island of Rügen and for the German part of the Bornholm Energy Island project.
It will also install the cables on the seabed. Bornholm Energy Island is being implemented by 50Hertz together with the Danish system operator Energinet.
In the North Sea, NKT is responsible for the implementation of the offshore grid connection project LanWin 6 (NOR-13-2 area) as well as the onshore HVDC project DC 32 (NordOstLink +) between the survey areas of Pöschendorf in Schleswig-Holstein and Klein Rogahn near Schwerin in Mecklenburg-Western Pomerania.
NKT has also been contracted for the SuedOstLink+ (SOL+) project.
This extra-high voltage direct current (HVDC) transmission line will start at Klein Rogahn and join with the SuedOstLink (SOL), which is about to begin construction, in Wolmirstedt near Magdeburg.
NKT is already responsible for the production and installation of cables for SOL.
Prysmian Power Link, an affiliate of Prysmian Group, headquartered in Italy, is awarded the contract for a lot comprising the realisation of the offshore grid connection system LanWin 3 (NOR-11-1 area) in the North Sea comprising of both the supply and installation of the subsea cables and the eastern part of onshore DC 31 NordOstLink (NOL), which is to start from the Heide survey area in Schleswig-Holstein and run mostly on the same route as NOL +.
Engineering, production and installation of the cable systems are scheduled to begin in 2025 and be completed with full commissioning in the mid-2030s.
In addition, 50Hertz enters into a framework agreement for the supply and installation of an additional 2,700 km of cable. Contracting parties for this framework agreement are both Prysmian and NKT. ■
