The project involved the refurbishment of the 132 kV AL Route, a 14.23 kilometre overhead line (28.46 kilometre double circuit) supported by more than 50 steel towers. In addition to strengthening the electricity network, the project provided opportunities for businesses across southern Scotland, with five local contractors playing a key role in delivering the works.
The project also supported 11 trainees in beginning their careers in energy, including one from SP Energy Networks and ten from Bathgate based principal contractor Aureos.
“We're proud that much of the activity associated with this project has supported local businesses and create opportunities for trainees setting out on their careers in energy” said Guy Jefferson, Transmission Managing Director at SP Energy Networks. “It has directly benefited contractors and communities from across the region; supported local jobs and economic growth while delivering infrastructure that will serve customers for many years to come.”
Principal contractor Aureos delivers energy and transportation schemes across the UK including a host of energy upgrade projects in Scotland. As part of their work with SP Energy Networks, Aureos harnessed the talent of a network of local companies and recruited trainees locally to help them deliver the upgrade.
Originally constructed in 1958, the route is a key part of the transmission network in southern Scotland. The refurbishment programme included detailed tower condition assessments, maintenance works, foundation upgrades and the replacement of conductors and insulators to ensure the long-term reliability and resilience of the line.
Sustainability was also central to project delivery with three native trees being planted for every tree or shrub removed during construction, helping to enhance local biodiversity and support habitat regeneration.
The project also reused materials wherever possible; aggregate used to create temporary working platforms was subsequently reused by local landowners, while approximately 600 tonnes of stone was transferred to repair and improve an existing track, ensuring valuable materials remained in productive use rather than becoming waste.
Throughout the works, SP Energy Networks worked closely with local landowners and stakeholders to facilitate access and minimise disruption.
The completed refurbishment forms part of SP Energy Networks' wider investment programme to maintain and modernise the transmission network, ensuring a safe, secure and reliable electricity supply while supporting the transition to a net zero future.
