Beauly-Denny Overhead Line Upgrade
A major milestone in the development of the Scottish transmission network was achieved in November with the energisation of the Beauly to Denny 400/275kV overhead line.
The project has been undertaken in conjunction with Scottish Hydro Electricity Transmission Limited (SHETL) with SP Transmission being responsible for the construction of a major new 400/275kV substation at Denny and 20km of overhead line from Denny to the boundary with SHETL.
The new line is an essential element in the development of the UK transmission system to facilitate renewable generation and to help Scotland realise its renewable energy potential, carbon reduction targets and support security of supply. The line will transport renewable energy from the North of Scotland to the Central Belt, where the integration at Denny facilitates its onward transmission over SPT’s existing network.
Construction began at the substation site in 2012 with the overhead line works starting in 2014. The main deliverable have now been achieved, work continues on the project, including the undergrounding of some 132kV circuits in the Stirling area which will allow 50 transmission towers to be removed and other visual mitigation measures continue to minimise the impact of the new overhead line on local communities and residents.
