Italy’s Prysmian Group will develop the Viking Link, a submarine transmission cable connection between the UK and Denmark planned by a unit of National Grid and Danish grid operator Energinet.

Worth close to $780m, the contract includes the turnkey design, manufacture and installation of an interconnector with the entire 777-mile cable for the submarine route and all of the nearly 84 miles of land cables on the UK side. Commissioning of the project is scheduled for the end of 2023.

The high voltage direct current (HVDC) interconnector will operate at ± 525 kV DC and will allow up to 1400 MW of power to be transferred between the two countries passing through UK, Dutch, German and Danish waters, using single-core, mass-impregnated paper-insulated cables. 

The HVDC cable system will connect the converter station located in Lincolnshire, UK, to the converter station located at Revsing in southern Jutland, Denmark, with the aim of increasing access to renewable and sustainable energy sources to more than 1.4 million households, reducing the cost of electricity in the UK and providing additional system reliability.

All cables will be manufactured at Prysmian’s facility in Arco Felice, Italy. The offshore cable operations will be performed using Prysmian’s new installation vessel. With an investment in excess of $190m, this strategic asset will reinforce Prysmian’s approach as a one-stop-shop solution provider, able to offer enhanced project flexibility thanks to its advanced features.
