Italy’s Prysmian Group reports that it has been awarded a major grid connection project, DolWin5, worth some €140 million, from Dutch-German grid operator TenneT.

A press release said that the TenneT project will connect multiple offshore wind farms to the German grid. It calls for “the supply, installation and commissioning of a High Voltage Direct Current (HVDC) 320 kV XLPE-insulated submarine and land power cable connection, with a transmission capacity of 900 MW, as well as the associated fibre optic cable system, comprising a land route of 30 km and a subsea route of 100 km.” The turnkey connections will link the offshore converter platform DolWin epsilon, located some 100 km offshore in the German North Sea, to the mainland Emden/Ost converter station, and help transmit the generated renewable energy into the German grid.

The cables will be manufactured at Prysmian Group’s plants in Pikkala, Finland, submarine, and Gron, France, land, the release said. Offshore installation activities will be performed by two Prysmian cable-laying vessels: the Cable Enterprise, for deep water installation, and the Ulisse, for shallow water activities. Completion of the project is scheduled for the middle of 2024.

“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,” said Hakan Ozmen, EVP Projects, Prysmian Group.

The release said that the project comes “at a very important time for Prysmian,” which recently won a €200 million U.S. offshore project from Vineyard Wind, LLC.
