UK, Scotland: Two new transformers have arrived at SSEN Transmission’s Errochty Grid Supply Point, important for enhancing the reliability and capacity of the network. The Errochty Grid Supply Point began construction in late 2023 and is set to be energised in mid-2026.
The 90 MVA 132/33 kV transformers safely arrived at the site, located at Tummel Bridge in Highland Perthshire, in November following a complex delivery operation. This involved careful coordination and planning with Police Scotland, Local Authorities, Transport Scotland, Amey, BEAR Scotland and specialist haulier JB Rawcliffe.
The Errochty Grid Supply Point is being upgraded to help facilitate the increase in renewable energy which is being generated from the Tummel Hydro Power Station. The transformers, the largest components in the new Errochty Grid Supply Point project, will play a crucial role in increasing the site’s ability to handle higher electricity loads, improve operational efficiency, and help enable the connection of renewable energy being generated from the nearby Tummel Power Station.
The project will see the existing site extended to facilitate the installation of the transformers along with appropriate 132 kV and 33 kV switchgear to create a new Grid Supply Point (GSP). The point will provide a 33 kV connection point to accommodate all generation and demand currently served by Tummel Bridge GSP, including the requested capacity increase for Tummel Bridge Hydro Power station. Once completed, the existing Tummel Bridge GSP will be decommissioned and removed.
