Project Timeline

What’s been done so far in the North Wessex Downs, what is coming up and what will happen if the project is taken forward?

2022 – 2024

Subject to planning approval, construction will commence in spring 2022 and take approximately two years to complete (including the removal of 11 pylons and the existing overhead line).


We will issue a planning application for the scheme to Wiltshire Council in 2021. This will be preceded by formal public consultation to show our proposals to the public and gather feedback which will be used to shape the application.


Further detailed ground investigation (GI) works will be taking place in autumn 2020 which will help to inform the preparation of a planning application.

Virtual engagement events are planned to bring the project to life for the people of Devizes and beyond.


We have carried out a range of archaeological and environmental surveys and this work will continue throughout 2020. We have met with a range of local stakeholders and interest groups  to introduce them to the project and gather feedback and local knowledge.


National Grid working with local partners established a Stakeholder Reference Group. The following organisations regularly attend these technical meetings:

  • Wiltshire Council
  • North Wessex Downs AONB Partnership
  • Natural England
  • Historic England


Our work on delivering a landscape and visual enhancement project in the North Wessex Downs began in spring 2019.  The section of overhead line near Devizes had been earmarked for removal from over 100 alternatives following an independent study as having a major landscape and visual impact.
