     Viking Link 

    Viking Link is a proposed 1400 MW high voltage direct current (HVDC) electricity link between the British and Danish transmission systems connecting at Bicker Fen substation in Lincolnshire and Revsing substation in southern Jutland, in Denmark.

    Project Partners

    Viking Link is being jointly developed by National Grid through National Grid Viking Link Limited and its other subsidiaries, and, the Danish transmission system operator. 

    Project overview

    The Viking Link project will involve the construction of a converter station in each country and the installation of submarine and underground cables between each converter station and underground cables between the converter station and substation in each country. The submarine cable will pass through Dutch and German territorial waters and and National Grid will discuss the project with the relevant authorities and stakeholders in these countries. 

    Viking Link will be approximately 760km long and will allow electricity to be exchanged between Great Britain and Denmark.

    Offshore Work 

    Viking Link will include approximately 630km of submarine high voltage Director Current (DC) cables running across the North Sea between Great Britain and Denmark, while passing through Germany and The Netherlands Exclusive Economic Zone (EEZ). We are working with relevant stakeholders, national authorities and other organisations to help us identify a marine cable route and landing points in Great Britain and Denmark. 

    Any environmental impacts will be assessed, and a routeing study and detailed offshore surveys will be carried out to determine the optimum route.

    The seabed survey commenced in mid March 2016 in Danish waters and will make its way from east to west across the southern North Sea, through German and Dutch waters before ending in the UK.

    We are in contact with all identified third party asset owners, local fishing communities and local statutory authorities to advise of the survey activities and programme in the relevant waters.

    There are three possible GB landfall points. The recently concluded GB phase 1 public consultation will help to determine a preferred landfall site option. In an effort to have data available, the offshore routes to access the three landfall areas are expected to be surveyed.

    Onshore work 

    National Grid Viking Link Limited (NGVL) has been carrying out studies and assessments to identify options for the onshore works, including where the converter station could be sited and the landfall point where we can bring the offshore cables ashore.

    Public consultations in Great Britain

    Discussions have been held with representatives from local authorities, statutory bodies, parish councils as well as local residents near potential site options. These have helped inform our site selection assessment and shortlisting process for a converter station and a landfall point.

    The GB Public 1 public consultation on shortlisted converter station and landfall sites was held in April/May 2016. Detailed consultation feedback and site selection reports will be published shortly. Public participation events and a further phase of consultations on the cable route options and converter station design will be held between July and September 2016.

    Public consultations

    The Nature Agency, under the Danish Ministry of Environment, initiated its first public consultation on the Environmental Impact Assessment (EIA) process of the land-based technical elements for Viking Link in Denmark on 30th May 2016.The consultation closed on 26th June 2016.

    Public consultations in Germany and The Netherlands closed on 11th August 2016.

    A detailed report on the Danish, Dutch and German consultations will be published later in 2016.

    Throughout the planning and construction stages of the project, members of the Viking Link team will be available to answer any questions you may have.
