On the UK side of the link, the sub-sea cable will come to land in Scotland near Long Haven Bay, south of Peterhead. An HVDC cable will be required onshore to carry the electricity from the landfall location to the converter stations. The electricity will be converted from HVDC to High Voltage Alternating Current (HVAC) in order to connect to the National Grid. A cable is required to connect the converter stations to a substation which will be connected to the grid system.
 

Constuction

Following development and detailed design work it is anticipated that construction will happen between 2019 – 2021.

The construction of the converter station and HVAC cable in the UK will last approximately 30 months. The majority of works will be carried out during the day to minimise noise impacts to local residents, however from time to time there maybe requirements to work on evenings, weekends and at night. These activities will be strictly controlled to minimise nuisance impacts on local residents.

The construction will be undertaken in 4 phases: preliminary works, site preparation and stage 1 landscaping, Converter build and HVAC cable installation and landscaping and reinstatement.

Further information about the construction of the UK Converter Station and onshore AC cable route are contained within the Environmental Statement

Permitting

NorthConnect recognise that due to the scale of the development and its proximity to designated areas there is a potential to have an effect on the environment. These effects need to be understood to allow appropriate avoidance techniques and mitigation to be identified.  The regulators and their statutory consultees will require this information to inform the decision making process.  NorthConnect will carry out a voluntary EIA and produce a voluntary Environmental Statement (ES) to support the planning and marine licensing applications for the HVDC cable.

A scoping report was submitted to Marine Scotland in April 2016 to seek agreement from all key stakeholders on the assessment methodologies to be utilised as part of the EIA process. Scoping opinions were received from Aberdeenshire Council in May 2016 and Marine Scotland July 2016. Insert link to the scoping report and opinions from both Aberdeenshire Council and Marine Scotland.
 

Converter Station & Cables


NorthConnect has received planning consent for the converter station on the ‘Fourfields’ site near Boddam, Peterhead and cable route connecting the converter station to the Peterhead substation. Aberdeenshire Council unanimously voted to approve the planning application at their meeting on the 27th August 2015.

HVDC cable
NorthConnect are currently working to the Interim Consultation Plan and are working on a consultation plan for the HVDC cable route.

The planning process for the High Voltage Direct Current (HVDC) cables that will transmit electricity between Scotland and Norway under the North Sea, started in 2016.

In order to complete an environmental impact assessment, a number of surveys will be undertaken which will consider a full range of environmental and socio-economic impacts in order to determine the exact route that the onshore and offshore cable will take. This includes seabed surveys, bird surveys and ecology surveys.

The Environmental Statement is available to read here.
The Planning Consent is available here.
 

Seabed Survey

A corridor between the UK and Norway has been identified taking a number of aspects into consideration. The exact route that the cables will take within the corridor across the North Sea to Simadalen in Norway has yet to be determined.  The final cable route design will take into account input from stakeholders and results of a detailed subsea survey.

UK nearshore subsea survey work, within the Buchan Ness to Collieston Special Protection Area (SPA), will be undertaken in winter 2016/17 to avoid the bird breeding season.  Offshore surveying will be undertaken in Summer 2017.

The cable route survey will provide information to support the assessment of marine effects on commercial fisheries, ecology, archaeology, seabed and water quality. The outputs of the survey will also aid in the identification of offshore cable protection requirements and appropriate installation technique selection.
