Supergrid transformer to be delivered to new Overton substation in North Yorkshire
A supergrid transformer delivery will be made to an electricity substation under construction in Overton on Sunday 6 July 2025.
Once operational, the transformer, weighing in at 200-tonnes – will help to change the voltage of electricity so that it can be supplied safely to homes and businesses.
Part of a package of improvement works to upgrade and reinforce the network in the area - eight supergrid transformer to be delivered to substations in Overton and Monk Fryston.
An essential piece of equipment is due to be delivered to an electricity substation under construction in Overton on Sunday 6 July 2025.
Transformers play a vital role in helping to ensure the UK continues to enjoy safe and reliable energy supplies, stepping voltage up or down so electricity can be efficiently transmitted from power generators or safely distributed to homes and businesses via regional networks.
The delivery is the latest milestone in National Grid’s Yorkshire GREEN project, part of the Great Grid Upgrade.
Weighing at 200-tonnes – the equivalent of 33 African elephants, 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.
Martin McGready, National Grid project director, 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.
We have carefully planned the delivery in collaboration with the police and National Highways to ensure we minimise disruption.
Some unavoidable disruption is expected as a rolling road closure will be in place in some areas, and temporary parking restrictions may be required. In addition, temporary alterations to items such as road signs and street furniture may have to be made at some locations to enable the convoy to complete its journey.
Letters have been sent to local residents directly affected by the deliveries, and Yorkshire GREEN’s dedicated Community Relations Team can be contacted by members of the community who have questions using the following contact details:
