Scottish and Southern Electricity Networks (SSEN) Transmission has secured Section 37 consent from the Scottish Government for its proposed 132kV overhead line replacement project near Dunoon, advancing plans to modernise critical electricity infrastructure in the region.
The consent authorises the construction of approximately 18 kilometres of double-circuit overhead lines, featuring 77 new steel towers ranging from 23 to 39 metres in height, with average spans of 230 metres. The new line will connect Dunoon substation to the west side of Loch Long and link with the existing network operated by SP Energy Networks to the east.
The project will replace infrastructure dating back to the 1970s, enhancing local electricity network resilience and contributing to national clean power and energy security objectives. Once the new infrastructure becomes operational, the existing 132kV line will be dismantled.
“This is a welcome step forward for our transmission network locally and throughout our network area in Scotland,” said Laura McWilliams, project director at SSEN Transmission. “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.”
She added, “As we now move to the delivery phase of the project, we are committed to working constructively with local communities and businesses to minimise and mitigate construction impacts, alongside maximising the economic opportunities this investment will bring.”
The Dunoon line rebuild is part of SSEN Transmission’s broader reinforcement plans across Argyll and Bute, designed to support the growth of renewable energy and strengthen electricity supply across western Scotland.
