UK, Scotland, Tealing–Westfield: SSEN Transmission has received Section 37 consent for the reconductoring and uprating of the Tealing to Westfield overhead transmission line, a major milestone in Scotland’s ongoing grid modernisation programme.
The project involves upgrading approximately 37 km of the existing 275 kV line to operate at 400 kV, increasing network capacity to accommodate growing volumes of renewable generation. The works will include replacing conductors, insulators, and fittings, as well as reinforcing tower foundations and steel structures to enhance long-term reliability.
Construction is expected to begin in 2026, with local contractors such as Dundee Plant already engaged in early development. Principal contractor Balfour Beatty will invite local suppliers to participate in the construction phase, further supporting regional employment and supply chain development.
The Tealing–Westfield project is also set to deliver around $9.7 M (£7.4 M) in community benefit funding, contributing to over $13 M (£10 M) of combined local investment when paired with the recently approved Alyth–Tealing reconductoring project.
“These upgrades are essential to strengthen Scotland’s transmission network, helping deliver clean, homegrown power across the country,” said Gregor Stirton, Project Manager at SSEN Transmission. “We’re committed to providing meaningful community benefits while ensuring Scotland’s grid is ready for the future.”
The Tealing–Westfield reconductoring forms part of SSEN Transmission’s $29 B ( £22 B) Pathway to 2030 programme, which aims to boost national energy security and support the UK’s transition to net zero.
