Project timeline

An overview of key VIP project milestones

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. It will include the removal of up to 13 pylons and the existing overhead line as well as the start of work to restore the landscape and enhance biodiversity in the area.


We will issue a planning application for the scheme to Wiltshire Council in 2021. Before this, we’ll carry out more formal public consultation to show our proposals to the public and gather feedback which will be used to shape the application.

WINTER 2020/21

Detailed ground investigation (GI) works will take place during the winter of 2020/21. These will enable us to work out the best alignment for the underground cables and the precise locations of the sealing end compounds.

We are updating Wiltshire Council, local parish councils and Devizes Town Council on our progress and plans.

Virtual engagement events are planned in early 2021 to bring the project to life for the people of Devizes and beyond.


We carried out a range of archaeological and environmental surveys throughout 2020. We will need to revisit some of these in 2021.


We met with a range of local stakeholders and interest groups to introduce them to the project and gather feedback and local knowledge of the area.


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 was earmarked for removal from over 100 alternatives following an independent study as having a major landscape and visual impact.
