Wind Energy – Grid Connection

Prysmian Group has been awarded two major contracts for a total value in excess of €800 million.

This includes options by Amprion Offshore for the design, supply, installation, and commissioning of land and submarine cables for two offshore wind farm grid connection systems in Germany’s North Sea, namely DolWin4 & BorWin4.

The DolWin4 & BorWin4 projects will transmit together a power of 1.8 GW.

Prysmian will supply approximately 1000 km of HVDC (High Voltage Direct Current) ±320 kV single core copper cables with XLPE insulation. The submarine cables will be produced in Pikkala, Finland and Arco Felice, Italy, and the land cables will be produced in Gron, France and Abbeville, USA. Prysmian will install the subsea cables with a variety of state-of-the-art vessels, ensuring lowest possible environmental impact. Delivery and commissioning for both projects is scheduled for 2028.

Each of the cable systems consists of 2 HVDC cables and can transmit 900 MW power. On the land side, the two systems run on a main part of the route in parallel trenches to the 300-km A-Nord underground cable corridor, a project awarded to Prysmian in 2020 by Amprion and which is currently in the execution phase. The subsea cables will run from the offshore platforms via the national park ‘Niedersächsisches Wattenmeer’, crossing the island Norderney before being connected to the onshore cables close to Hilgenriedersiel.

“This is Prysmian’s first 320kV HVDC submarine project with Amprion Offshore, and remarks how Prysmian is consolidating its prominent role as a reliable partner in supporting Germany’s energy transition, being involved in major infrastructure projects supporting growth of green energy usage. We are honored to work with Amprion to develop its first offshore wind project,” said Hakan Ozmen, EVP Projects BU, Prysmian Group.

Prysmian is already playing an important role in supporting European energy transition, having been involved in key offshore wind farms projects like BorWin2, BorWin3, DolWin3, HelWin1, HelWin2, and SylWin1, Dolwin 5 (expected to be commissioned in 2023) in Germany; Borssele III & IV, Hornsea 2, Hollandse Kust Zuid 3 and 4 and Provence Grand Large in Europe, and Empire Wind in the US.
