UK, Scotland: After almost 30 months of construction, a new substation in Highland Perthshire was energised this month. The new Kinardochy Substation, located about three miles from Tummel Bridge, will play a role in ensuring voltage limits on the transmission network remain stable and power flows can be efficiently managed, allowing for the connection of renewable generation and helping enable the transition to net zero.

Built to an operating capacity of 275 kV, it is designed so that it can be increased to 400 kV with minimal operational changes. The substation connects into the existing Beauly-Denny overhead line, set to be upgraded to a double-circuit 400 kV line as part of SSEN Transmission’s Pathway to 2030 programme. The platform has been sized to ensure that any additional equipment can be constructed with minimal works required.

The construction included the installation of a 195-tonne static compensation transformer (SCT), the largest component in the substation build, which required a specialist haulier with a 24-axle vehicle to deliver it and the installation of 275 kV double busbar gas insulated switchgear and reactive compensation equipment.

Consideration has been taken to preserve the area, with the substation built into the slope of the land so it is naturally screened by the landscape. SSEN Transmission teams were careful to manage environmental impacts during the build, with extensive work carried out to make sure that the project had minimal impact. The project was delivered following engagement with the community and stakeholder groups.

SSEN Transmission Project Manager Muhammed Saeed Chaudhary said: “We’re now turning to the final stages of work which involves removing the site cabins and equipment, fencing and tree planting, and we’ll do everything we can to keep any disruption to a minimum and keep the local community informed of our progress.”
