New transformer arrives in Bramley to help future-proof local rail network

97 tonne Supergrid transformer delivered by sea and road

National Grid has delivered a new 97 tonne transformer which will connect a new trackside substation at Holly Cross to the electricity network, as part of the Bramley Network Rail connection.

The Supergrid transformer at Bramley substation will help Network Rail to future-proof and decarbonise its electrical network.

The delivery faced a number of challenges caused by low water levels in The Rhine in Germany following the drought in Europe this summer. But the team overcame the problem by adapting the original delivery plan. The transformer was transported by barge along The Rhine and across the English Channel to docks in Tilbury, before travelling to Bramley by road.

A large specialist vehicle (37 metres in length) transported the transformer to Bramley on Sunday 18 September. On arrival the slow-moving vehicle travelled at 10mph along Sherfield Road, The Street, and into St James Park estate, then reversed down the National Grid access road before proceeding to the substation.

Such low speeds were necessary to ensure the safety of all road users when transporting heavy loads. The route had been carefully planned in collaboration with Hampshire County Council’s highways department to minimise disruption, and local residents and businesses were informed. Many residents turned out on the day to watch the abnormal load navigate the roads through the village.

National Grid Project Manager, Stephen Harris, said:

“The transformer delivery has been many months in the planning, and we have worked hard to overcome the challenges and minimise the disruption to the local community.

“We appreciate the cooperation and understanding of local residents and businesses in helping us achieve this significant milestone in the project.”

National Grid is now focused on completing the installation of underground cables between Bramley substation and the feeder station. Completion is expected in late-2023.

Notes to Editors:

National Grid is pivotal to the energy systems in the UK and the north eastern United States. We aim to serve customers well and efficiently, supporting the communities in which we operate and making possible the energy systems of the future.

National Grid in the UK:

  • We own and operate the electricity transmission network in England and Wales, with day-to-day responsibility for balancing supply and demand. We also operate, but do not own, the Scottish networks. Our networks comprise approximately 7,200 kilometres (4,474 miles) of overhead line, 1,500 kilometres (932 miles) of underground cable and 342 substations.
  • We own and operate the gas National Transmission System in Great Britain, with day-to-day responsibility for balancing supply and demand. Our network comprises approximately 7,660 kilometres (4,760 miles) of high-pressure pipe and 618 above-ground installations.
  • As Great Britain’s System Operator (SO) we make sure gas and electricity is transported safely and efficiently from where it is produced to where it is consumed.  *From April 2019, Electricity System Operator (ESO) will be a new standalone business within National Grid, legally separate from all other parts of the National Grid Group. This will provide the right environment to deliver a balanced and impartial ESO that can realise real benefits for consumers as we transition to a more decentralised, decarbonised electricity system.
  • Other UK activities mainly relate to businesses operating in competitive markets outside of our core regulated businesses; including interconnectors, gas metering activities and a liquefied natural gas (LNG) importation terminal – all of which are now part of National Grid Ventures. National Grid Property is responsible for the management, clean-up and disposal of surplus sites in the UK. Most of these are former gas works.
