Viking Link is a proposed 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 will be approximately 760 km long and will allow electricity to be exchanged between Great Britain and Denmark.
It will be 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.
- 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
These are shown below
Energinet and National Grid Viking Link Ltd. have published a Project Information Leaflet and a Non-Technical Summary (NTS) highlighting the project proposals. The NTS will be updated in line with regulatory requirements.
The GB Phase 1 consultation on site options for the converter station and landfall point took place between 11 April and 20 May 2016. On 22 August 2016, preferred sites were confirmed for a landfall and converter station.
Between 5 September and 14 October 2016, the project held a Phase 2 consultation on the underground DC cable route corridor options between the preferred landfall and converter station sites and on 14 December 2016, confirmed a preferred route corridor option for the underground DC cables with options to route around settlements at the northern and southern end of the corridor. On 15 March 2017, the route options at the north and south ends of the corridor were confirmed.
The Phase 2 consultation also invited thoughts on the design options for the proposed converter station. Feedback was provided to the local planning authorities as part of the planning applications for the UK Onshore Scheme.
