SSEN Transmission Gains Consent for Overhead Line Rebuild Project in Dunoon

Wedoany.com Report-Oct. 15, Scottish and Southern Electricity Networks (SSEN) Transmission has received Section 37 consent from Scottish Ministers to reconstruct a 132kV overhead line in Dunoon, Scotland. The project aims to strengthen energy reliability and support clean energy goals by modernizing the region’s electricity infrastructure.

The project involves the installation of 77 new steel towers.

The initiative focuses on upgrading aging infrastructure, some dating back to the 1970s, to ensure a robust transmission network in Argyll and Bute. The approved plan involves installing approximately 18km of new double-circuit overhead lines, extending from Dunoon Substation westward to the point where the line crosses Loch Long. The project includes 77 new steel towers, ranging in height from 23m to 39m, with an average span of 230m between them. Once the new line is operational, the existing 132kV line will be dismantled.

SSEN Transmission project director Laura McWilliams stated: “This is a welcome step forward for our transmission network locally and throughout our network area in Scotland. The Section 37 consent from the Scottish Government for our Dunoon project reflects SSEN Transmission’s commitment to delivering a modern, efficient, and environmentally responsible transmission network that will enhance local network resilience, replace ageing electrical infrastructure, and help us reach clean power and energy security goals.”

The project integrates with the network operated by SP Energy Networks east of Loch Long. SSEN Transmission is committed to minimizing construction impacts on local communities and businesses while maximizing economic benefits from the investment. The company oversees the high-voltage electricity transmission network in northern Scotland, managing 132kV, 220kV, 275kV, and 400kV systems.

Earlier this year, in April, SSEN announced a £200m ($258m) investment to enhance the electricity distribution network in Oxfordshire, UK, further demonstrating its commitment to improving energy infrastructure. The Dunoon project aligns with broader efforts to modernize and future-proof electricity networks, supporting sustainable energy solutions and reliable power delivery for communities across Scotland.
