National Grid T-pylons work starts – public information events

From May 2020, National Grid are starting work to build the world’s first T-pylons from Bridgwater to Loxton, where they will connect with the underground cables being installing across the Mendip Hills. The first activity will be to build temporary road accesses and a temporary haul road along the route of the new overhead line. This will help to keep construction traffic away from local roads.

Construction activity in this area will include:

temporary entrance and access roads
temporary haul road
pylon foundations and structures

Over the coming weeks people may see them carrying out surveys and vegetation clearance. Before they start work in May, they will write to properties close to the route and meet with the parish councils to keep them updated.

We are also holding public information events where you can come along to meet our project team and find out more.

Woolavington Village Hall CANCELLED

Tuesday 21 April 2020 

4.00pm – 6.30 pm

The Hinkley Connection Project is a new high-voltage electricity connection between Bridgwater and Seabank near Avonmouth. It will connect low-carbon energy sources, including EDF Energy’s new     Hinkley Point C, to UK homes and businesses. The new connection will be 57 km long: 48.5 km of overhead line and 8.5 km of underground cable through the Mendip Hills.

To minimise the impact on the local landscape and make way for the new connection, they are removing over 67 km of existing overhead lines and pylons.


Unfortunately, due to COVID-19, National Grid has had to postpone plans to meet with parish councils and local residents for the foreseeable future. They are sorry that they are unable to come and meet residents in person to provide more information on the start of construction for the T-pylons in May. Instead they are staying in contact by telephone and are providing information by email and on their website at . They will also write to residents along the route.

The meetings will be rearranged when the restrictions have passed.

In terms of management of COVID-19, they are working with their contractors to ensure stringent measures are in place to prevent the spread of the virus, in line with Government guidelines. These include restricting movement between sites and social distancing.

Currently, surveys, ecological mitigation work and construction activity will continue as planned across the project but they recognise that this is a changing situation and will do their best to keep people updated.

During the week commencing Monday 23 March, Balfour Beatty will be carrying out some ecological mitigation on the rhynes along the route to protect water voles during the forthcoming construction work.

Members of the public may see staff with machinery working on the rhynes, occasionally this will be close to roads but not on the carriageways.

When they are delivering equipment down two very narrow country lanes, they will need to close them to traffic for a  short period of up to 15 minutes to allow them to safely turn the vehicles into the fields. The two roads affected are Pill Road and Vole Road in Mark.

They will need to close them again for 15 minutes when they bring the equipment out again.

They are sorry for any disruption to journeys and any inconvenience this may cause.
