National Grid is set to deliver a new 155-tonne supergrid transformer to its West Weybridge substation in New Haw near Addlestone, upgrading the facility by replacing an aging asset. The transformer, roughly the weight of 25 African elephants, will be transported from the Port of Tilbury on the evening of Saturday, November 16, arriving at the substation in the early hours of Sunday, November 17, 2024.
Transformers are essential for maintaining safe, reliable energy supplies by adjusting voltage levels so electricity can be efficiently transmitted or safely distributed to homes and businesses.
The transformer will be transported on a specialized vehicle traveling at a maximum speed of 12 mph, accompanied by a police escort. The convoy will depart Tilbury, enter the M25, and exit at Junction 11 around midnight. It is expected to arrive at the substation around 3 a.m.
The carefully planned route, designed with highway authorities and police, includes temporary adjustments like removing street furniture to accommodate the large transporter. The convoy will head from the Wisley Interchange west along A320 St Peter’s Way, turning at Ottershaw roundabout and traveling through various roads in the area, ensuring minimal disruption to local traffic.
Mark Ellis, Project Manager for National Grid, said, “This delivery has been meticulously planned for months to minimize potential disruptions. Moving at night aims to reduce impact on local roads, and noise will be kept to a minimum. We’re grateful for the community’s patience and cooperation as we undertake this critical work to support the resilience of our energy network.”
