About the Project

A number of significant projects connecting to the transmission network has triggered the need for a 400kV substation at Leylodge, Kintore.

Each year the electricity system operator (National Grid ESO) assesses all proposed network reinforcements across Great Britain and provides a recommendation on whether these proposals should proceed. This is called the Networks Options Assessment (NOA). The NOA in 2018 and 2019 has provided “Proceed” signals for the East Coast and North East network to be reinforced to 400kV operation.

To allow this, the North East and East Coast networks require reinforcement via a new substation at Kintore. This involves a phased development of a new substation operating at 400kV, with ‘Phase 1’ completed to tie in with the network north of Kintore in October 2023 and ‘Phase 2’ completed for the network south of Kintore energising to 400kV operation in 2026.

To ensure the security and quality of supply of electricity in the transmission network we are proposing several upgrades and reinforcements across the North East and East Coast of Scotland. More information on all these developments and the drivers for these proposed works can be found here.

Design Considerations

At present, SSEN Transmission are currently considering two options for the design of the proposed Kintore substation, one of which involved the use of Air Insulated Switchgear (AIS) equipment and an alternative which uses Gas Insulated Switchgear (GIS) equipment.

As part of our commitments and responsibilities to the decarbonisation of the GB electricity network it has been the view of SSEN Transmission that an AIS option is the preferred solution, however due to recent advancements and innovations of switchgear technology, SSEN Transmission has been provided with an opportunity to consider a lower carbon potential GIS substation.

Currently we have consulted with members of the local community on a more developed AIS solution, whilst introducing the potential opportunities that exist regarding recent switchgear advancements. Prior to submitting a planning application, SSEN Transmission have committed to return to consult with members of the local community, focusing on a more detailed GIS substation design.

Who is Scottish and Southern Electricity Networks?

Scottish and Southern Electricity Networks is the trading name of Scottish and Southern Energy Power Distribution Limited, Scottish Hydro Electric Transmission plc, Scottish Hydro Electric Power Distribution plc and Southern Electric Power Distribution plc.

How are Transmission network upgrades paid for?

Investments in projects are made by SHE Transmission plc. Electricity transmission companies are authorised to recover the costs of such investments through 'use of system' charges which are levied by National Grid Electricity Transmission plc on generators and suppliers of electricity. Suppliers recover their costs from all electricity customers. In order to protect the interests of customers, the transmission companies have to demonstrate to the energy regulator, Ofgem (Office for Gas and Electricity Markets) that proposed investments are necessary, are efficient and are economical so that the charges which are ultimately levied on all electricity customers are justified.


This means SHE Transmission is subject to a funding mechanism established by Parliament and regulated by Ofgem. Cross subsidies between different businesses in the SSE group is not permitted.

What is the transmission network?

It’s the highest voltage electricity network in the UK – the ‘motorway network’ of the energy world. It transmits large quantities of electricity over long distances via wires carried on a system of mainly metal towers (pylons) and large substations. Transmission voltages in Scotland are 132kV, 275kV and 400kV. Larger generation schemes usually connect to the Transmission system.

The lower voltage parts of the system are called distribution networks. In Scotland, these local networks operate below 132kV whereas in England the distribution network includes 132kV. 

How are proposals scrutinised?

The Scottish Ministers are responsible for determination of applications submitted under Section 37 of the Electricity Act 1989. Both statutory consultees and members of the public have the right to submit their representations on the application. All representations will be considered by Scottish Ministers in their determination of the application.
The Office for Gas and Electricity Markets (Ofgem), as the regulator, has to approve all investment so project proposals are developed under license conditions.
Preferred route corridors chosen will comply with revised ‘Holford Rules’ which are the recognised industry approach to routeing overhead lines amended to reflect Scottish circumstances.

How and to what extent are electricity consumers' interests considered?

SHE Transmission are regulated by the Office for Gas and Electricity Markets (Ofgem), the regulator responsible for representing consumers' interests. Electricity consumer interests are therefore one of our key drivers and this is enshrined in our statutory duties under the Electricity Act.


In particular we have a statutory duty to develop, maintain and operate an efficient, economic and co-ordinated transmission system. Since the costs of these projects will ultimately be paid for by electricity consumers, we have a responsibility to take cost into account with due weighting in a comparison against other important factors.

Extension to Working Hours

From Thursday 9th of June the working hours for our Principal Contractor working at Kintore substation site, Leylodge will be extended. The new working hours that have been agreed by Aberdeenshire Council will be; 07:00 hours to 19:00 hours Monday to Friday, the works that will be carried out during these additional hours will be within the existing substation. There will be tower lights on while the works are ongoing, but these will be switched off at the end of each night. Weekend working will also commence within the existing substation on both Saturday’s and Sunday’s between 07:00 hours to 19:00 hours. SSEN Transmission will review the requirement for these additional working hours on an ongoing basis. The extended working hours are necessary for the project to meet grid connection dates and reduce the longevity of the overall project. SSEN Transmission apologises for any inconvenience that these changes may cause to the local community and thank you for your continued understanding as our project progresses. If you have any questions or queries in relation to the project, please do not hesitate to contact the Community Liaison Manager (dav.s.lynch@sse.com)

April 2022 - Update

Significant progress had been made on the construction of the Kintore 400kV Substation over the last few months. The earthworks “cut and fill” operation is now complete and the completion of the main retaining wall has been carried out. The 2 Supergrid transformer oil containment bunds have successfully been put in place and the main building steelworks have now been erected. Over the next few months the cladding of the building roof and walls will be carried out and various internal works will take place within the building. The upcoming months will also see the installation of concrete support foundations and installation of platform drainage pipes and cable ducting. To view images of the progress on site please see our “Progress gallery” in the project overview section of this website.

May 2021 Update

Following the approval of the Kintore substation by Aberdeenshire Council, we expect to begin enabling works in July of this year to set up our Site Welfare facilities adjacent to the substation junction off the B977 before moving on to the earthworks exercise in August which will be led by our Principal Contractor Omexom. The Earthworks, which consists of stripping of top soil and temporary bunding prior to processing of under lying material including rock breaking, processing and placement of graded material is expected to continue until end Q1 2022 with concrete and building erection works to continue thereafter.

Planning Application Determination

SSEN Transmission welcomes the approval of the Kintore substation by Aberdeenshire Council, which once constructed, will be the world’s first 400kV Green Gas for Grid (g3) substation. The new, innovative clean gas technology will result in a reduction of emissions equivalent to removing 138,000 cars from our roads for one year when compared to traditional substation gas technology. The new substation will be built to the West of the existing substation at Leylodge and is a key component in SSEN Transmission’s reinforcement and improvement of the transmission network in the North East and East Coast of Scotland. It will facilitate the connection of new renewable electricity to the National Grid and will also help control the flow of energy across the North East, helping transport renewable electricity to where it’s needed, supporting the transition to net zero emissions and the fight against climate change

Section 37 Application

On the 31st of July 2020 we submitted two planning applications in support of our proposals. A town & country planning application was submitted to Aberdeenshire Council and can be found at the following location; https://upa.aberdeenshire.gov.uk/online-applications/search.do?action=simple&searchType=Application Planning ref: APP/2020/1437. We have also submitted an application to Scottish Ministers for consent under section 37 of the Electricity Act 1989 relating to the over head line elements of our proposal. We have been working closely with the Energy Consents Unit to ensure that, during the COVID-19 restrictions imposed by the UK and Scottish Governments, the application can be processed formally and in accordance with all relevant Regulations.

Kintore Substation Design Change

On the 3rd of March 2020 we held a public consultation in Kintore regarding our proposals to submit a new planning application for a 400kV Air Insulated Swtichgear (AIS) substation at Leylodge, Kintore. At this consultation we committed to returning to the area before submitting our planning application to present further information on alternative solutions to our currently consented proposal. Due to the on-going COVID-19 pandemic and in line with Scottish Government guidance, we cannot host a secondary public meeting on this matter, in lieu of this we have created an additional information brochure showing our intention to submit planning for a 400kV Gas Insulated Switchgear (GIS) substation and the details of our proposal. The information brochure can be downloaded from the Project documentation section, we would encourage all interested parties to please read this information and submit any feedback either online or directly to the Community Liaison Manager; Gary Donlin by the 5th of June 2020.

Feedback Period Closed

The feedback period following our consultation event on the 3rd March has now closed and the project team will now review all submitted feedback over the coming weeks. This consultation focused heavily on our proposals for an Air Insulated Switchgear (AIS) substation. We had originally planned to return to Kintore to hold a public consultation discussing our proposal for a Gas Insulated Switchgear (GIS) substation, however in line with current advice from the Scottish Government, we do not deem this safe during the current COVID-19 pandemic. It is still the aim of the project team to create consultation materials on our GIS proposals and make these readily available for members of the public to comment on ahead of any planning submission. Once we have done this we will be in touch with residents to provide a further update on the project, however in the meantime if you have any queries or issues then please do not hesitate to contact the project Community Liaison Manager.

Kintore Public Consultation Feedback Period Open

SSEN Transmission would like to thank all who took the time to attend our recent consultation event in Kintore. It was fantastic to see such a great turn out from members of the local community and to hear their thoughts on our proposal for a new 400kV substation at Leylodge, Kintore. Our deadline for feedback following these events is on the 31st of March and the project Community Liaison Manager will be discussing all submitted feedback with the project team over the coming weeks. Once we have done this we will be in touch with residents to provide a further update on the project, however in the meantime if you have any queries or issues then please do not hesitate to contact the project Community Liaison Manager, Gary Donlin.
