Final delivery timings confirmed for Creag Dhubh transformer movements

22 June 2026

We have confirmed the final delivery timings for the movement of two Super Grid Transformers to its Creag Dhubh substation project in Argyll.

The deliveries are part of a coordinated operation to transport major electrical equipment to the new substation site near Cladich, which will help strengthen the local electricity transmission network and support the growth of renewable energy across Argyll and Kintyre.

The first stage of the transformer movements from Clydebank has now been completed, and the next phase will require two overnight closures on the A82 between Crianlarich and Tyndrum. These closures are needed to allow the transformers to travel safely to Dalmally before continuing on to the Creag Dhubh site.

The closures will take place as follows:

  • Transformer 1: 7pm on Wednesday 24 June to 6am on Thursday 25 June
  • Transformer 2: 7pm on Friday 26 June to 6am on Saturday 27 June

A section of the road at Inverherive, at the Herive Burn, will be closed during these periods to allow the loads to pass safely.

Local diversions and signage will be in place, and access for emergency services will be maintained throughout the closures. The transformers are then expected to continue from Dalmally to the Creag Dhubh site on Saturday 27 June and Monday 29 June respectively.

Lee Biddulph, SSEN Transmission’s Project Manager for the Creag Dhubh substation project, said:

“We have already completed the first stage of our transformer movements from Clydebank and are now preparing for the next series of overnight moves to Dalmally, beginning on Wednesday 24 June with the first transformer, followed by the second on Friday 26 June.

“This is a complex operation, and we continue to work closely with our road traffic partners to minimise disruption. Changes to delivery schedules are common for movements of this scale, as they depend on weather conditions, safety checks and close coordination with partner organisations.

“We are grateful for the continued patience and support of the public and our partner organisations as we deliver infrastructure that will strengthen the local network and support renewable energy growth across Argyll."
