New transformer to be delivered to Sellindge substation in Kent

National Grid's picture

A new transformer is to be delivered to Sellindge substation in Kent to keep electricity flowing to homes across the county and beyond.

29 Dec 2017

  • Transformer to be delivered to Sellindge substation


  • 318 tonne piece of equipment will keep electricity flowing across the South East and beyond


  • Delivery carefully planned to keep traffic moving and hotline set up for enquiries

A big load will take to the road at approximately 9pm on Saturday 6 January 2018 as National Grid moves a transformer from the Port of Dover. It is expected to arrive at Sellindge substation by 7am on Sunday 7 January. To keep disruption to a minimum, we’re moving it overnight.

The equipment which weighs in at 318 tonnes will be installed at the substation to help National Grid continue to deliver electricity to homes and businesses across the South East and beyond.

Most of National Grid’s substations were built between the 1950s and 1970s and equipment such as transformers need to be replaced and maintained to keep them working efficiently. New transformers are also installed to connect new sources of generation or when demand for electricity is growing.

Phil Billington, National Grid Project Engineer said: “Our network operates smoothly, safely and efficiently over 99.9999% of the time – a statistic we’re very proud of. Millions of people rely on us to supply their electricity without interruption, day in, day out and so it’s important that we keep our substations and the equipment in them working efficiently.”

The transformer will be carried on a special transporter measuring 87 metres long and 5.8 metres wide. It’s so big that it needs two trucks, one at the back and one at the front, to propel it. It will travel at around 12 miles an hour and will take the following route:

It will exit the Port of Dover at Union Street and will travel along the A20 to the Alkham Valley Road junction (A260 – Canterbury Road). It will then continue along the A259 (Churchill Avenue) to access the M20 at junction 13.

It will exit the M20 at junction 9 and re-join it to travel back to junction 10. This is due to a weight restriction at this junction. The load will then leave the M20 at junction 10, travelling along the A20 and Church Lane before reaching the Sellindge electricity converter station.

If people have questions about the delivery, they can ring the National Grid hotline on 0800 731 1231 between 9am and 5.30pm or email
