Dutch-German grid operator TenneT has awarded Prysmian a contract valued at €140m for the 900 MW DolWin5 offshore grid connection in the German North Sea.

The DolWin5 project will enable the connection of multiple offshore wind farms to the German electricity grid. Prysmian will supply, install and commission a High Voltage Direct Current (HVDC) 320 kV XLPE-insulated submarine and land power cable connection.

The cable will have a capacity of 900 MW. Prysmian will also supply and install the associated fibre optic cable system.

The cables will link the offshore converter platform DolWin epsilon, located approximately 100 km offshore in the German North Sea, to the mainland Emden/Ost converter station.

“The Dolwin5 project continues our valued long relationship with the major TSO TenneT and demonstrates our ability to provide tailor-made submarine cable solutions for challenging projects, providing the offshore infrastructure needed to support the growth of clean energy in Northern Europe,” stated Hakan Ozmen, EVP Projects, Prysmian Group.

The submarine and land cables will be manufactured at Prysmian Group’s centres of technological and manufacturing excellence respectively located in Pikkala (Finland) and Gron (France). Offshore installation activities will be performed by two of the Group’s state-of-the-art cable laying vessels – Cable Enterprise, for deep water installation, and Ulisse, for shallow water activities.


Completion of the cable project is scheduled for the middle of 2024.
