Two large supergrid transformers arriving at new substation

National Grid will deliver two large supergrid transformers to a new East Sussex substation, which is under construction near Little Horsted, Uckfield, on Sunday 27 October 2024. The transformers will travel in convoy from Shoreham Port in Brighton to the substation, a journey of 24 miles.

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.

Each weighing 178 tonnes, they will help to futureproof electricity supplies to the surrounding area and continue the safe and secure supply of electricity to local homes and businesses, as part of the Little Horsted substation construction. 

Leaving the port around 8am, the journey is expected to take around 6-8 hours. The transformers are transported on specialist vehicles with a police escort, with a top travelling speed of 12 mph.

The route has been carefully planned in collaboration with the highway authority and the police to minimise disruption. Road users are advised to allow extra time for their journeys. Some street furniture may be removed temporarily in preparation for the transformers’ journey to site. In some areas traffic may be held briefly for the convoy to pass.

Paul Alchin, National Grid Project Manager, says: “These transformer movements have been many months in the planning and we’ve worked hard to minimise any disruption that large deliveries of this kind can cause. We appreciate the cooperation and understanding of the local community during this vital work to futureproof electricity supplies and meet local demand.”
