Overview
About the Project
In order to support the continued growth in onshore and offshore renewables across the north of Scotland, supporting the country's drive towards Net Zero, investment in network infrastructure is needed to connect this renewable power and transport it from source to areas of demand across the country.
Extensive studies have confirmed the need for a new 400kV connection between Kintore and Tealing, connecting into new 400kV substation sites at Hurlie in Fetteresso Forest and at Tealing (Emmock.) The existing overhead line between Kintore and Tealing is currently operating at 275kV, and cannot be upgraded to 400kV as the conductors would not be able to achieve safe clearance distances due to the size of the towers. The project includes the following elements:
- A new 400kV connection between Kintore and Hurlie
- A new 400kV connection between Hurlie and Tealing (Emmock)
- New 400kV substations at Hurlie and Tealing (Emmock)
This is part of the East Coast 400kV Phase 2 projects, a scheme consisting of several onshore reinforcement projects on the east coast of Scotland.

Pathway to 2030
The Pathway to 2030, published by National Grid ESO, the electricity system operator for Great Britain, sets the blueprint for the electricity transmission network infrastructure required to enable the forecasted growth in renewable electricity across Great Britain.
The projects identified within the Pathway to 2030 are critical to delivering the UK and Scottish Government’s offshore wind targets. To deliver these targets, we are investing over £20bn to upgrade the network infrastructure across the north of Scotland as the region plays a leading role in the clean energy transition.
As part of this investment, there is a requirement for a new 400kV connection between Kintore and Tealing.
Stakeholder Engagement
Public consultations took place in May 2023 to inform the community on progress to date with the East Coast 400kV Phase 2 Projects. We sought feedback from local communities and all interested parties on the interim preferred routes for the proposed Kintore - Tealing 400kV Overhead Line.

In this video, Senior Project Manager Calum Grant describes the approach we are taking to develop our proposals and the opportunities that are available for stakeholders to feed into the design process. This process aims to progress towards an optimal site in a systematic manner, which is technically feasible, economically viable, and could be anticipated to cause the least disturbance to the environment and to those who live, work, and visit the area.
How we’re embracing artificial intelligence (AI)
We intend to use AI to assist our experienced teams in the analysis of your feedback, so we can categorise key points raised more quickly. You can learn more about how we’re utilising AI on this dedicated web page.
The East Coast 400kV Phase 2 Upgrade Projects
The East Coast 400kV Phase 2 is a scheme consisting of several onshore reinforcement projects on the east coast of Scotland, comprising new and upgrade of existing infrastructure. The majority of the infrastructure projects are within our operational area in the north of Scotland.
To provide the full 400kV capability that the scheme intends to deliver, there are several projects that contribute to the full scheme:
- An extension to Kintore 400kV Substation (currently under construction)
-
A new 400kV substation within the vicinity of the existing Fettersso substation
-
A new 400kV substation within the vicinity of the existing Tealing substation
-
A new 400kV connection between Kintore, Fetteresso and Tealing
-
An upgrade to the existing Alyth - Tealing 275kV Overhead Line
-
An upgrade to the existing Tealing - Westfield 275kV Overhead Line (to the Scottish Power Transmission operational border)
-
Connection of the upgraded Alyth - Tealing and Tealing - Westfield Overhead Lines into the proposed Tealing Substation

Report on Consultation
Our Reports on Consultation across our three new overhead line projects and associated substation and convertor station developments have now been published. These reports provide a summary of the extensive feedback received during consultation, how this has been considered and confirmation of which routes and substations are now being taken forward to the next stage of development.
Our Reports on Consultation are now available to download from the Project Documentation tab.
Summary Reports on Consultation are also available for each of the three schemes and can be downloaded below:
- Summary Report on Consultation Spittal to Beauly
- Summary Report on Consultation Beauly to Peterhead
- Summary Report on Consultation Kintore to Tealing
A stakeholder webinar available for all to join will be held in the coming weeks to share the changes informed by the feedback. More information about the forthcoming webinar will be shared on our events page shortly.
In further recognition of community feedback, we will seek to rationalise cumulative infrastructure impacts through the removal and undergrounding of existing transmission lines, where technically practical and appropriate, and subject to all necessary planning consents and landowner agreements.
Work to identify and assess potential sections of existing overhead line where their removal will reduce cumulative impacts is ongoing, with an update expected as part of the next round of public consultation on overhead line alignments and more detailed substation designs in early 2024.
We would once again like to thank all stakeholders who took the time to engage with our early consultation process. We will continue to engage with stakeholders ahead of consulting further with local communities and stakeholders in the new year, as we look to refine our proposals.

Report on Consultation
Over the course of this year, we have undertaken extensive consultation on plans to upgrade the electricity transmission network across the north of Scotland and have received a considerable amount of feedback from a wide range of stakeholders regarding our proposals.
We recently advised in our next steps for 2030 network developments update that following assessment of consultation feedback and additional options analysis, we would publish our Report on Consultations (RoCs). These reports provide a summary of the feedback received and how it has been considered, which options we will take forward to the next stage of the development process and any changes to options initially consulted on.
It is our intention to publish the RoCs during the week commencing 27 November. All stakeholders signed up for updates on the project will receive a link to the report and we will also issue Summary Reports to help ensure accessibility.
These Report on Consultations mark the completion of the first round of non-statutory consultation, where we sought feedback on the corridor, route, and substation locations. We will be consulting further with local communities and stakeholders in the new year, as we look to refine the projects, therefore we welcome an open channel of communication and would like to reassure all stakeholders that there will be further opportunities to engage on this project.
Our Reports on Consultation and Summary Reports on Consultation are now available to download from the Project Documentation tab. -
