SSEN Transmission to hold consultation event on proposals to replace Dunoon substation

SSEN Transmission is holding a public consultation on its proposals to replace the existing Dunoon 132kV substation.

A pre-application consultation event will take place from 2–7pm on Tuesday 17 March at Dunoon Burgh Hall, where members of the public will be able to discuss the plans with the project team.

The current Grid Supply Point (GSP) substation at Ardnadam has been in operation since 1971 and is now approaching the end of its operational capabilities.

To maintain network resilience, we are proposing to build a new 132kV substation near the existing site. This upgrade is part of wider work to modernise critical infrastructure and support the long‑term energy needs of communities across Argyll and Bute.

Jason Tyler, Project Manager for the Dunoon 132kV Substation Replacement Project, said:

“Replacing the existing substation is vital to ensuring Dunoon and the wider region continue to benefit from a safe and reliable electricity transmission network.

By investing in modern infrastructure, we can maintain security of supply for homes and businesses while preparing the network for the future.

We’re encouraging members of the public to come along to our consultation event at Dunoon Burgh Hall on Tuesday 17 March and speak with the project team about our plans.

Your feedback will play an important role in shaping our proposals before we submit our planning application for the project, and we welcome all comments and feedback on our proposals. The feedback period is now open until 28 April 2026.”
