The first of two supergrid transformers has reached SSEN Transmission's Crossaig North substation in Argyll, marking a significant step forward in the company's wider Argyll & Kintyre energy infrastructure programme.

Weighing about 200 tonnes — roughly equivalent to 33 adult African elephants — the unit was shipped from Poland to Campbeltown Harbour before beginning its final leg to site. The carefully managed operation included an escorted journey along the A83 and a transfer to a remote-operated 14-axle trailer to complete the final 24km via a dedicated access track.

The move was planned and coordinated extensively to minimise disruption to local communities and road users while ensuring the safe delivery of the critical equipment.

Supergrid transformers are among the largest and most vital assets on the transmission network. By adjusting voltage levels, they enable electricity to be carried efficiently over long distances, helping transport renewable power from where it is generated to homes, businesses and public services. With the first unit now on site, teams will begin installation into the electrical system.

Crossaig North is a new 275kV substation being built as part of SSEN Transmission's Argyll & Kintyre Strategy to strengthen the region's transmission network and support Scotland's renewable energy ambitions. The delivery follows recent transformer arrivals at the Creag Dhubh substation further north, demonstrating ongoing progress across the programme.

A second transformer has already arrived safely at Campbeltown Harbour and is due to be transported to Crossaig North in the coming weeks.

Ali Awada, Project Manager at SSEN Transmission, said: "The successful delivery of our first transformer to Crossaig North is a major milestone for the Argyll & Kintyre project and reflects the significant planning and collaboration involved in transporting equipment of this scale safely to site.

"From its journey by sea from Poland to its carefully managed transport along the A83 and access track, every stage of the operation has been designed to minimise impacts on local communities while maintaining the highest standards of safety.

"Following the recent successful transformer deliveries to Creag Dhubh, this latest milestone demonstrates the continued progress we're making across the project as we invest in the infrastructure needed to support Scotland's clean power ambitions and future energy security."

The delivery forms part of a wider programme to increase network capacity across Argyll and Kintyre, enabling more renewable generation to connect and be transported across the region.
