Churchill
Work at Churchill substation is complete
We are working to make significant changes to the local electricity network by removing 67 kilometres of existing overhead line and pylons.
National Grid and its contractor completed work to upgrade the existing substation at Churchill and to modify the electricity network to the east of the substation in July 2020, hitting a milestone in our programme to build the Hinkley Connection Project.
The upgrades reinforce the local electricity network in the South West region before we remove the existing lattice pylons from Bridgwater to Avonmouth.
