Hurlie to Kintore; Overhead Transmission Line Upgrade

Fairhurst was appointed by MGroup in October 2024 to provide Civil Engineering design, Structural Engineering design, and Geotechnical Investigation Design and reporting required for the temporary works, including all Public Road Improvements, Belmouths, access tracks, compounds and crane platforms, compounds, bridges and associated drainage design to facilitate the construction of the new 400kV connection between Kintore and Hurlie.

In order to support the continued growth in onshore and offshore renewables across the north of Scotland, supporting the country’s drive towards Net Zero, investment in network infrastructure is needed to connect this renewable power and transport it from source to areas of demand across the country.

Studies by SSE have confirmed the need for a new 400kV connection between Kintore and Tealing, connecting into new 400kV substation sites at Fetteresso Forest known as Hurlie and at Tealing known as Emmock. The existing overhead line between Kintore and Tealing is currently operating at 275kV, and cannot be upgraded to 400kV as the conductors would not be able to achieve safe clearance distances due to the size of the towers.

The project includes a new 400kV connection between Kintore and Hurlie (Fairhurst current commission). 

This is part of the East Coast 400kV projects, a scheme consisting of several onshore reinforcement projects on the east coast of Scotland.
