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

Viking Link is approximately 765 km long and allows electricity to be exchanged between Great Britain and Denmark.

It is made up of the following components:

The North Sea

  • A pair of high voltage direct current (DC) submarine cables extending for approximately 620 km between Great Britain and Denmark crossing the Dutch and German waters. The cables will be buried in the sea bed.

Great Britain

  • A pair of onshore underground high voltage DC cables from the landfall site at Boygrfit, East Lindsey to a converter station at North Ing Drove, South Holland
  • The converter station would convert the electricity from direct current (DC) to alternating current (AC).
  • High voltage alternating current (AC) underground cables from the converter station to the existing National Grid substation at Bicker Fen, Lincolnshire 
  • New equipment within the existing substation


  • A pair of onshore underground high voltage DC cables from the west coast of Jutland to the existing 400 kV substation Revsing near Vejen 
  • Converter station to convert electricity between DC and AC
  • New equipment within the existing 400 kV substation at Revsing
