Viking Link is a joint venture between National Grid Ventures, part of National Grid, and Danish system operator.

The 1.4 GW high voltage direct current interconnector, which will be the longest in the world when completed, will stretch 472 miles from the Lincolnshire coast to Western Denmark.

The project will consist of two parallel HVDC (High Voltage Direct Current) cables which will be manufactured and installed by Prysmian Powerlink S.r.l. and NKT HV Cables AB. Prysmian will deliver four of the five cable lots and NKT will deliver the onshore cable lot in Denmark.

Industrial manufacturing company Siemens will be supplying and installing equipment for two converter station sites in Lincolnshire, UK and Revsing, Denmark.

The three contracts have a combined value of 1.1bn euros (£990mn). Viking Link will now move from development to the construction phase, with work in the UK and Denmark beginning next summer. Construction on Viking Link is expected to be completed by the end of 2023.
