UK, England: National Grid will deliver a supergrid transformer to its West Weybridge substation in New Haw near Addlestone, helping to modernise substation equipment by replacing an asset that has reached the end of its working life. The transformer, weighing 155-tonnes will make its way from the Port of Tilbury on the evening of Saturday 16 November and arrive at the substation in the early hours of Sunday 17 November 2024.
The transformer will be delivered on a large specialist vehicle travelling at a maximum speed of 12 mph with a police escort. The convoy will travel from Tilbury via the M25, leaving at junction 11 around midnight. It’s expected to arrive at the substation around 3 am.
Its route has been carefully planned in collaboration with highway authorities and the police to minimise disruption. The vehicle will have a police escort to help manage traffic and some street furniture will be temporarily removed, so the convoy can make its way to the substation. Traffic may be held briefly to allow the convoy to pass.
Mark Ellis, Project Manager for National Grid, commented: “This transformer movement has been many months in the planning and we work hard to minimise any disruption that deliveries of this kind can cause. The movement is occurring at this time to try and minimise disruption to the local road network. Noise will be kept to a minimum. We appreciate the cooperation and understanding of the local community during this vital work maintaining the resilience of our energy network.”
