Italy-based Prysmian Group has been awarded a major grid connection project which will enable the connection of multiple offshore wind farms to the German grid.

Awarded by Dutch-German grid operator TenneT, the contract involves the supply, installation, and commissioning of a high voltage direct current (HVDC) 320kV 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 kilometres and a subsea route of 100 kilometres.

The turnkey connections will link the offshore converter platform DolWin epsilon, located approximately 100 kilometres offshore in the German North Sea, to the mainland Emden/Ost converter station, with the purpose of transmitting the generated renewable energy into the German grid.

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 cable laying vessels, Cable Enterprise (pictured) and Ulisse, for deep water installation and for shallow water activities, respectively.

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