The German transmission grid operators TransnetBW GmbH and TenneT have awarded contracts for the SuedLink Corridor in Germany to the Prysmian Group, The Corridor is the largest ever underground cable project. Under the contracts, together worth more than €800m, Prysmian is to design, manufacture, supply, lay, joint, test and commission a 2 GW underground cable system from North to South Germany.
Prysmian will deliver a complete ±525 kV HVDC underground cable system able to transmit 2 GW of electrical power, combining large copper conductors with extruded XLPE insulation technology at the highest voltage level. The route, with a length of around 700 km, from Wilster in Schleswig-Holstein, to the northwest of Hamburg, shall run the length of Germany to the southern connection point at Bergrheinfeld, close to Schweinfurt in Bavaria. This high-performance system shall be efficiently installed with optimized long length solutions, extending beyond 2 km, assuring highest levels of quality with a strong and dedicated local project engineering and management team. Project completion is planned in 2026.“
In the future we will see an increasing need for cables to export and transmit renewable energy over longer distances from both offshore and onshore wind farms. Our 525 kV cable systems will connect the wind generation-rich regions of Northern Germany to the major consumption areas further south,” said Hakan Ozmen, EVP Projects BU. “With SuedLink, Prysmian extends its involvement in strategic underground interconnection projects creating increasingly efficient and sustainable power transmission grids. Alongside the trust placed in us with the German DC Corridors, we can point to our positive commitments on other long high-power land projects, such as the Piedmont-Savoy connection, the INELFE link, as well as the ElecLink and the ALEGrO projects”.
These awards follow those recently secured by Prysmian for SuedOstLink and A-Nord Corridors, and with an overall value of around €1.8 billion.
