Prysmian Group has been awarded by TenneT TSO a contract for the SuedOstLink project in Germany, one of the longest HVDC underground cable connection.
Worth approximately €500 million depending on options, Prysmian are to design, manufacture, supply, lay, joint, test and commission a 2GW underground cable system through the TenneT region of this first German Corridor.
“This prestigious award confirms our ambition to play a strategic role in the shift towards a low-carbon economy and to drive the energy transition forwards with smarter, more reliable and more sustainable solutions. It gives us great satisfaction to be involved in the development of this vital infrastructure project and to set this milestone in the upgrading of the EU power transmission grid,” stated Valerio Battista, Prysmian Group CEO.
With SuedOstLink, Prysmian extends its involvement in strategic underground interconnection projects, alongside the Piedmont-Savoy connection between Italy and France, the INELFE link between Spain and France, the ElecLink project running through the Eurotunnel between France and the UK, and the ALEGrO connection between Belgium and Germany.
Prysmian will deliver a ±525 kV HVDC underground cable system, the first HVDC link to use extruded cables at this highest voltage level, combined with large copper conductor cables and Prysmian own developed innovative P-Laser insulation technology, with higher operating temperature, to enable a transmittable power of more than 2GW on a single system for the first time. The route, with a length of over 250 km, starts at the Southern Germany connection point at Isar, close to Landshut in Bavaria.
Prysmian will provide all related accessories, as well as an integrated PRY-CAM monitoring system. A high-quality and efficient installation shall be assured with optimised long length solutions, extending beyond 2 km, overseen by a strong and dedicated local project engineering and management team. Project completion is planned in early 2026.
