Overview
Status: Operational Phase
About the Project
The project comprises the following elements:
Knocknagael to Tomatin
Construct approximately 20km of 275kV double circuit overhead line between Knocknagael and Tomatin Substations on a new alignment.
Knocknagael to Farr
Dismantle the existing 132kV overhead line between Knocknagael and Farr Substations.
Tomatin Substation
Construct a new 275/132kV substation near Tomatin, adjacent to the existing Beauly to Boat of Garten 132kV double circuit overhead line. This project was completed and energised in 2019.
Knocknagael Substation
Connect the existing 132kV overhead line from Beauly to Knocknagael via a new sealing end compound (where overhead lines terminate onto underground cables), and connect the proposed Knocknagael to Tomatin 275kV overhead line via a new sealing end compound.

Transformer Delivery to Tomatin Substation 2018
With the exterior complete and the work on the interiors progressing well, October 2018 saw the delivery of the two transformers which will sit at the heart of Tomatin Substation.
- The transformers were manufactured in Milan, shipped to Inverness via Venice and then delivered by road to Tomatin, a total of over 4,000 miles.
- Each transformer weighs 194 tonnes, which is roughly equivalent to 43 African elephants
- The specialist haulage vehicles, including 3Nr. Large traction lorries, known as Trojans, each weigh 460 tonnes (loaded) and have a total of 280 wheels
“Watching the transformers make the final part of their journey down the A9 and on to our site at Tomatin was incredibly satisfying, as it marked the culmination of many months of hard work and planning behind the scenes by not only our own team, but also the manufacturers in Milan and our specialist haulier.” - Alistair Muir, Project Manager
Watch the video below of the Transformers being delivered to Tomatin Substation, which was connected to the grid in 2019:
Why is the Project Required?
As the transmission licence holder in the north of Scotland, we have a duty under Section 9 of the Electricity Act 1989 to facilitate competition in the generation and supply of electricity. We have obligations to offer non-discriminatory terms for connection to the transmission system, both for new generation and for new sources of electricity demand.
The aim of the project is to enable renewable energy to connect to our transmission network. Under our Network Operators Licence this connection should be efficient, co-ordinated and economic, whilst having the least possible impact on the environment.
Community Engagement
Throughout the life of our projects, we aim to work positively with local communities and keep people informed about what we are doing. This is particularly important when we are developing a proposal and we want to understand what local people think about our plans.
We endeavour to take the time to discuss proposals with local community councils, encourage engagement from the wider community and listen to the feedback we receive.
We will do our best to answer any questions and address issues or concerns that are raised with us.
When our project progresses into construction, we will continue working closely with the local community to ensure that our work has as little impact on the lives of those living and working in the area and as many long term positive effects as possible.
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.

We're here to lend a helping hand
We are committed to supporting the communities in the north of Scotland where we operate, both now and in the future. As part of our ongoing efforts to make a difference and have a positive impact on local communities, we are proud to offer volunteering days to local groups and charities, particularly in the areas that host our electricity infrastructure or where our proposed projects are located.
This month, we’re excited to announce the launch of our new Volunteering Webpage, designed to make it easier for local communities to request volunteering support from us. To request our help, simply complete the ‘Volunteering Nomination Form’ linked at the bottom of our new webpage. Please note, as our team works on a voluntary basis, it may take us some time to coordinate our people and match them with opportunities. We kindly ask for your patience as we work to keep up with volunteering demand.
Thank you for considering SSEN Transmission as a partner in your community efforts. Together, we can leave a positive, lasting legacy and help transform communities across the north of Scotland.

Boat of Garten to Tomatin 132kV Re-conductoring
In December 2019 we submitted to The Highland Council a planning application for the retention of access track (retrospective) at Telecommunications Tower, Slochd, Carrbridge, under reference 19/05582/FUL.The Highland Council on the 11th of February 2020 granted this planning permission and therefore the access track will remain. All other access tracks will be reinstated by the end of March 2020.

Power to the pupils as local school gets involved in transformer deliveries
Pupils at Strathdearn Primary School have been getting a unique insight into the planning and logistical tasks behind the delivery of two 194-tonne transformers to SSEN Transmission's newly constructed Tomatin substation.Given their size and the various modes of transport that were used as part of the transformers’ installation, SSEN Transmission’s project team thought that their pan-continental journey could lend itself to an interesting project for the local primary school pupils, and so contacted Judith Pirie, Headteacher at Strathdearn Primary School.Judith Pirie said that the mini-project was very much in line with current initiative in education to generate an interest in, and connections with, careers associated with science, technology, engineering and mathematics (STEM) subjects and was also useful for illustrating the wide range of employment roles that are out there. She also said that the pupils enjoyed meeting the teams from SSEN Transmission and their contractor Amey, and it gave them a fascinating insight into what was a very complex technical operation. -
From Milan to Tomatin via Venice and the A9
As the owner of the transmission network for the north of Scotland, SSEN Transmission has an important part to play in the UK’s transition towards a low-carbon economy, as more and more renewable generators are looking to connect to the grid.One of SSEN Transmission's large scale infrastructure projects which will help with this increasing demand for connections is the newly built substation at Tomatin, 16 miles south of Inverness. Construction started in January 2018, and prior to that the substation was three years in planning.With the exterior complete and the work on the interiors progressing well, earlier this month saw the delivery of the two transformers which will sit at the heart of the £39m premises.Now that the transformers are in place, the construction phase of Tomatin substation is nearing completion, and SSEN Transmission is hoping to have it connected to the grid and energised in July 2019.To see one of the transformers on the last leg of its journey to the Tomatin substation, click on the image. -

School pupils set to go Farr in project management
The pupils of Farr Primary have been working together to look at ways of improving their school garden to make it fully inclusive for everyone at the school and reached out to us to make their ideas a reality. When Farr Primary approached the CLG for help, our overhead line contractors, MSVE, stepped up and offered to provide the pupils with a fully interactive project management experience, from initial site survey through to design, construction and completion.Colin Kelly, MSVE Construction Manager, explains, “To date, our team of engineers have visited the school and with the help of appointed team leaders have surveyed the garden. Layout drawings will be produced to scale allowing the pupils to interact with the current layout and design their new garden. From there, through visits with the school, we will turn their drawings into a reality showing the pupils every step involved in designing and building a project and show them the basic processes of a construction job.”
