Overview
Status: Operational Phase
About the Project
The 132kV double circuit overhead line between Inverness and Keith Substations has a total route length of 92km, 29km between Inverness and Nairn and 63km between Nairn, Elgin and Keith. The section between Inverness and Beauly was reconductored and reinsulated in 1992. The section between Beauly and Keith was constructed in 1955 and forms an integral part of the transmission system, which was upgraded between 2018 and 2021.
We invested in the network to fully refurbish many of the towers and replace the existing wires (conductors) starting from Beauly Substation in 2018 and finishing at Keith Substation in 2021. The new wires are capable of carrying increased amounts of electricity whilst ensuring the security of electricity supply.
There are some very challenging aspects along the route, including major road crossings (A82, A862 ,A96 and the A9), numerous railway crossings, and water crossings at the River Ness and Caledonian Canal. The overhead line also crosses through the residential area of Holm as well as historic sites such as Culloden Battlefield.
Project Activities
Some of the project activities undertaken are as follows:
- Some tree cutting along the route as required
- A number of tower foundation upgrades as required
- Tower steel strengthening
- New access tracks into tower locations as required
- Reconducting works (replacing existing conductors and fittings with new)
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.
