SuedLink: Contracts for underground cables awarded to Prysmian and NKT

In: CablesInterconnectors

TenneT and TransnetBW have selected NKT and Prysmian to supply and lay 525 kilovolt underground cables for the SuedLink. The two cable manufacturers will provide 2GW high-voltage DC underground interconnector. The contract has been valued around €2 billion.

Suedlink is an ~700 km long link in Germany, connecting the windy North with the South. The Link starts in Northern Germany where it connects to power from offshore wind farms and to the Nordlink interconnector, which brings hydro power from Norway to Germany via a 525 kV high-voltage DC offshore power cable to Southern Germany.

‘In the future, SuedLink will form the backbone of the energy transition in Germany. With the orders for the DC underground cables, we are now moving from planning to realizing this important power connection,’
said Tim Meyerjürgens, Managing Director of TenneT.

NKT will provide one of two power cable systems, with a specially engineered solution for the power cable to cross the Elbe river and a salt mine.

Prysmian will supply the other cable, with a length of around 700 km, from Wilster in Schleswig-Holstein, to the north-west of Hamburg, to the southern connection point at Bergrheinfeld, close to Schweinfurt in Bavaria. The contract is worth ~€800 million.

The project completion of both the cables is expected in 2026. The cables will be produced at NKT's facilities in Cologne and Karlskrona (Sweden) as well as at Prysmian facilities in Gron and Montereau (France) and in Pikkala (Finland).
