Overview – Winter 2022

In May 2021, National Grid started work to build the new 400,000 volt overhead connection along the northern section of the Hinkley Connection Project, between Sandford and Seabank substations. We are using the world’s first T-pylons for part of the route.

We’re working with Western Power Distribution (WPD) to make changes to their existing network and to connect the new WPD substation at Sandford. In July 2021, we started work to build nine new lattice pylons north-west of Sandford substation towards Puxton, divert and remove existing overhead lines in this area.

During 2023, we’ll remove existing WPD lattice pylons to the north and south of Sandford substation, bringing us a step closer to removing 67 kilometres of WPD’s overhead line by the time the Hinkley Connection Project is completed in 2025.

We recognise that our construction activity impacts local communities and work with our contractors to limit that as much as possible.

Modifications to the existing 132,000 volt overhead line to Weston-super-Mare

What we are doing:

  • Building a temporary entrance and access road to allow construction traffic to enter site from the local highway. You can find more information on our construction information page.

  • Building a new connection from Sandford substation to the existing overhead line that goes to Weston-super-Mare. It will be made up of 700m of underground cable and nine new lattice pylons. This is to ensure local electricity supplies are maintained.

  • Removing 1.5 km of the existing overhead line to Weston-super-Mare that runs north-west from Sandford towards Puxton.

This work will be done by Western Power Distribution.
