The transformer, which weighs 200 tonnes, forms part of National Grid’s Yorkshire GREEN project, which in turn is part of its Great Grid Upgrade programme.
This aims to upgrade and reinforce the network in the area, which eight supergrid transformer to be delivered to substations in Overton and Monk Fryston.
The first transformer will be delivered from Teesport Docks, Middlesbrough, on a specialist vehicle over 80 metres long under police escort and at low speed.
The transformer will travel along the road network via A19 southbound, past Thirsk, Thormanby and Shipton before arriving at Overton Substation on Overton Road.
This delivery will be the first of eight to substations in Overton and Monk Fryston, with four supergrid transformers being delivered to each site.
The deliveries will take place between July and October 2025.
National Grid project director Martin McGready said: “Supergrid transformers are essential to our project to upgrade and reinforce the high-voltage energy network in Yorkshire and further afield.
“We are working closely with other organisations to limit as much of the potential disruption as possible, and we’d like to thank local communities for their support and understanding while we undertake this vital work.”
National Grid’s Great Grid Upgrade programme is a plan to overhaul the UK’s transmission network to prepare for a wave of renewable energy projects and greater electrification of the UK’s economy.
The company awarded a series of deals to multiple companies under two parts of its £59-billion high voltage direct current supply chain framework.
These will help deliver various projects in the Great Grid Upgrade, including the Eastern Green Link 4, Sealink and Lionlink cables.
The 2GW Sealink grid connection between Kent and Suffolk recently had its consent application accepted by the Planning Inspectorate.
