SSEN Transmission has formally submitted a Section 37 application to the Scottish Government for a proposed 400kV overhead transmission line connecting Kintore in Aberdeenshire to Tealing in Angus, a key component of the company’s £22 billion Pathway to 2030 energy investment programme.
The proposed development aims to support the expansion of offshore wind and enhance the UK and Scotland’s long-term energy security and decarbonisation objectives. The project has already received approval from both the National Energy System Operator and Ofgem.
“Submitting our consent application for the Kintore–Tealing 400kV overhead line marks a major milestone in supporting UK and Scottish energy goals,” said Alison Hall, director of development at SSEN Transmission. “This project will unlock vital low-carbon electricity and strengthen the security and affordability of our energy system.”
The application follows what SSEN described as one of the largest public consultation efforts ever conducted in the north of Scotland, with more than 40 events and meetings held to gather local feedback and shape the final proposals.
In addition to the new overhead line, the project includes the construction of substations at Hurlie and Tealing, and the upgrade of existing infrastructure between Alyth and Tealing, and between Tealing and Westfield, to 400kV capacity.
The application will now be considered by Scottish Ministers under the government’s 52-week determination process for priority transmission infrastructure. A decision is expected within 12 months.
The Kintore–Tealing project forms part of broader efforts to modernise the UK’s electricity grid in response to rising demand for renewable energy and to meet net zero emissions targets.
