New transformer for Littlebrook substation

  • Littlebrook substation in Dartford is currently being upgraded
  • A large transformer delivery will be made to Littlebrook substation on 30 July 2022
  • Transformers represent vital investment in the UK energy network

National Grid will be moving a Super Grid Transformer from Tilbury Docks to its newly energised substation in Littlebrook. The transformer is part of a wider programme to build a new substation at Littlebrook, replacing the former substation that relied on a potent greenhouse gas sulphur hexafluoride also known as SF6. This gas is commonly used in the electrical industry to prevent short circuits and to keep the network safe and reliable.

The transformer will be transported on a very large specialist vehicle (58m in length, roughly equivalent to half a football pitch), travelling at a maximum speed of 20mph.

Leaving Tilbury Docks via A1089 at 7pm, the transporter will approach Littlebrook Substation by crossing the iconic Queen Elizabeth II Bridge. It is expected that the transformer will be delivered to Littlebrook Substation by approximately 9pm

The route has been carefully planned in collaboration with local highway authorities to minimise disruption and those directly affected have been informed. Residents and businesses along the route have been advised to avoid parking on the road while the transporter convoy passes their property. Individuals planning to travel along the route of the transformer movement are recommended to try to find alternative routes or allow additional journey time.

Richard Morris, project engineer for National Grid says: “This transformer movement has been many months in the planning, and we’ve worked hard to try and minimise any disruption deliveries of this kind can cause. We appreciate the cooperation and understanding of the local community during this vital movement.”

The vehicle will have a police escort to help manage traffic and some street furniture along Rennie Drive will be temporarily removed, including a pedestrian crossing to ensure the transporter convoy is able to progress safely.
