We have completed another key stage in our transformer deliveries to Creag Dhubh substation, with the successful movement of the first transformer from Stuckgowan to Dalmally. 

The operation, which required an overnight closure of a short section of the A82 between Crianlarich and Tyndrum from Wednesday into Thursday, took over seven hours to complete and demonstrated strong collaboration between key partners, including Police Scotland, which safely escorted the convoy along the route of more than 30 miles. 

The final movement of the transformer from Dalmally to Creag Dhubh substation is scheduled for tomorrow (Saturday 27 June).

Following a change to the previous schedule, the second transformer will now be transported from Stuckgowan to Dalmally overnight from 7pm on Saturday 4 July to 6am on Sunday 5 July, requiring a further overnight closure of a short section of the A82 between Crianlarich and Tyndrum. It will then continue from Dalmally to Creag Dhubh substation on Tuesday 7 July. 

Local diversions and signage will be in place during all movements, with access for emergency services maintained at all times.

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

“This latest movement highlights the strong partnership working that underpins these complex operations. Transporting equipment of this scale over long distances requires detailed planning and close coordination between multiple agencies, and I would like to thank everyone involved for their professionalism in delivering this safely and successfully. 

“As we look ahead to our next transformer movements, we will continue working closely with our road traffic partners to minimise disruption. Changes to delivery schedules are common for operations of this nature, depending on weather conditions, safety checks and careful coordination. 

“We are grateful to local communities, road users and our partner organisations for their continued patience and support as we deliver infrastructure that will strengthen the local network and support renewable energy growth across Argyll."
