The onshore part of the Viking Link project is known as the UK Onshore Scheme.
The UK Onshore Scheme comprises of the installation of underground direct current (DC) cables from a landfall point to a converter station; the construction of a permanent access road, as well as the installation of underground alternating current (AC) cables from the converter station to the existing substation at Bicker Fen.
Proposed converter station and landfall sites
Potential sites for a landfall point and a converter station were discussed with representatives from local authorities, statutory bodies, parish councils as well as local residents during the Phase 1 consultation which was held between 11 April and 20 May, 2016 on the shortlisted site options. These discussions helped to inform our site selection assessments.
Comments and feedback from this phase of consultation were carefully considered and, on 22 August 2016, we confirmed our preferred locations for the landfall point and converter station.
The proposed landfall point is at Boygrift, East Lindsey (adjacent to Sandilands Golf club) and the proposed converter station site is at North Ing Drove, South Holland (within the parish of Donington).
These are shown on the maps below.

Local opinion played an important part in the decision and we selected these sites after careful consideration of all the information provided by local people, along with environmental and technical information. We would like to thank everyone who participated in the Phase 1 consultation and provided comments.

More information on how we selected these sites is available in our UK Onshore Scheme: Preferred Sites Selection Report and details of the issues raised during the consultation and how they have been taken into account can be found in our UK Onshore Scheme: Phase 1 Consultation Feedback Report (Volume 1 - Introduction and Approach; Volume 2 - Feedback; Volume 3 - Appendices).
Proposed cable route corridor options between proposed landfall and converter station sites
We identified two broad route corridor options (purple and orange route corridors) where we might route the direct current underground cables between the proposed landfall and converter station sites. From Monday 5 September until Friday 14 October 2016, we held a Phase 2 consultation to ask local residents, landowners, farmers and other stakeholders for their views on these cable route corridor options and to see if there is anything else we needed to consider when deciding the proposed cable route.
After careful consideration of all the information and feedback provided along with the environmental and technical information available, the purple corridor was selected as the proposed cable route corridor for the underground cables between the proposed landfall and converter station sites as shown on the map below.
Within the purple route corridor there were options to route around settlements at the northern end and the southern end of the corridor. Further surveys and assessments were required before confirming the preferred route options for these two sections of the corridor.
On 15 March 2017, the proposed route corridor options were confirmed, subject to further survey.
The route corridor option to the east of the villages of Aswardby, Langton and Sausthorpe in the north section was chosen. Access to the major road network at this location provides direct routes to the proposed cable construction site.
In the south section, the route corridor option to the west of the South Forty Foot Drain was selected for the DC underground cables into the preferred converter station site. This option takes into account the feedback we received from local communities as well as other stakeholders during our Phase 2 consultation and helps to minimise any cumulative impact that may arise as a result of the alternating current (AC) cables which is needed to link the converter station to the National Grid 400kV substation at Bicker Fen.
Furthermore, there was an opportunity to adjust the route of the underground DC cable route corridor in the south section. This adjustment shortens the length of the DC cable route and reduces the land-take required during construction. It also provides a better location to cross the South Forty Foot Drain.

The purple route corridor, along with the east/west options confirmed is best placed to balance any potential impacts on the environment and local communities, with due consideration for other technical and engineering requirements.
The benefits of the purple route corridor include:
- Avoids larger settlements which will help to reduce potential construction impacts
- Avoids the lower lying coastal areas, where there is a higher water table and more watercourses and drains to cross
- Provides more opportunities for direct access to the construction works from existing roads
Following ongoing assessments, the corridor of interest for the underground cables has also been narrowed down from 1 kilometer to 200 metres wide. Assessments are ongoing to identify an alignment within this reduced corridor as well as suitable access points to the highway network and locations for temporary construction areas.
Detailed information on the results of the surveys and assessments will be published within the project’s Environmental Statement when we submit our planning applications in summer 2017.
During the Phase 2 consultation, we also asked for views on the design style for the converter station building. We will provide this feedback to the local planning authority as part of our planning application and as we work with them to develop a detailed design code for the building.

Over the coming months, we will continue our discussions with landowners, local authorities, statutory bodies and stakeholders while we carry out further technical and environmental surveys to help us identify a suitable alignment for our underground cables within the preferred route corridor.
Planning applications for the Viking Link UK Onshore Scheme will be submitted during summer 2017. The following affected Local Planning Authorities will be involved in determining the submissions:
- East Lindsey District Council
- Boston Borough Council
- North Kesteven District Council
- South Holland District Council
Before submiting planning applications, Viking Link has held a round of Public Information Events to share its updated draft proposals with local communities.

Onshore Work in Denmark
In Denmark, the project will connect to the Danish power grid at the existing 400kV substation in Revsing, southern Jutland.
The proposed direct current (DC) cable route is developed from technical, economic and potential environmental impacts.
An Environmental Impact Assessment (EIA) will be undertaken and the extent of the assessment will be agreed with the appropriate stakeholders
In the summer of 2016, the project consulted with the public and key stakeholders. Feedback received is being considered as part of the final proposals for the project and as part of the permit application process.
Once the environmental impact assessments are completed, public information events will be held in Summer 2017 to give citizens and key stakeholders a further opportunity to provide comments about the project.
