National Grid held a second non-statutory consultation for the Norwich to Tilbury transmission infrastructure project, formerly known as East Anglia GREEN.

The proposed project aims to construct approximately 183 kilometres of transmission infrastructure as part of The Great Grid Upgrade.

The NFU submitted a comprehensive response to this consultation on behalf of all members affected. In this response, any issues which impacted our members and require attention from National Grid were raised.

NFU responds to the Great Grid Upgrade: Norwich to Tilbury consultation

The NFU’s response to the second consultation goes into more depth over some of the issues we feel were not sufficiently addressed in National Grid’s response to the first consultation. We also held a member meeting in July 2023 in order to allow our members to feed back their concerns into our response.

Therefore, our response reflects the views and concerns brought up by our affected members, as well as exploring in more detail some of the previously raised issues.

In particular, we highlighted the lack of detail provided for a potential offshore route, and the NFU’s preference for a long term vision for an offshore grid which would minimise the onshore disruption for our members.

The response also explores in further detail:

  • The preferred draft alignment
  • The potential for unergrounding of electric cables
  • Pylon locations
  • Impact on heritage buildings/listed buildings/historic sites
  • Environmental mitigation and Biodiversity Net Gain
  • Soils
  • Engagement with landowners

National Grid consults on its preferred draft alignment

The consultation period will run for eight weeks, concluding on 21 August 2023.

This stage represents the early development phase, and National Grid is seeking feedback on its preferred draft alignment. The alignment showcases potential positions for overhead lines, associated pylons, underground cables, cable sealing end compounds (where overhead lines connect to underground cables), and connection substations.

Constructive feedback from stakeholders and the public will play a vital role in refining and enhancing the project's proposals.

To facilitate the consultation process, National Grid will be conducting online webinars that will provide a comprehensive presentation of the project details, followed by a dedicated question and answer session. The webinar schedule is as follows:

  • Saturday 12 August: 10-11am
  • Thursday 17 August: 10-11am

For detailed information and access to interactive maps and consultation materials, interested parties are encouraged to visit the National Grid's website at: Nationalgrid.com | Norwich to Tilbury

How can I take part?

Individual landowners and their appointed agents will receive communication regarding the consultation process and will be offered meetings to discuss the proposed draft route alignment. 

For any inquiries or further information, please call the Norwich-Tilbury lands team on: 0808 1753 314 or email at: [email protected]

The NFU strongly encourages all affected farmers affected by the proposed route to actively participate in this consultation.

Your input is crucial in highlighting any concerns you may have regarding pylon locations. Additionally, please ensure that you inform National Grid about any features that could potentially influence pylon placement, such as listed buildings.

We highlight issues in our response to the consultation

The NFU responded to the consultation on behalf of farmers and growers.

Our response highlights issues including the lack of underground and offshore options that have been considered and the need for the project in light of the review currently being undertaken into the offshore transmission network.

Our response looks at:

  • Scheme route
  • Requirement for the network reinforcement
  • Alternative technologies
  • Offshore
  • Underground
  • Alternative tower types
  • Environmental mitigation and biodiversity net gain
  • Consultation with landowners
  • Impact on agricultural businesses
  • Amount of land to be taken for the scheme

Further engagement

We would like to engage further with National Grid on behalf of members that may be affected by the proposed scheme.

We would like to hold a meeting with National Grid once further information is available on the cables being laid underground and the possibility of the cables being offshore.

Next steps

National Grid anticipate launching its statutory consultation in May 2023 before submitting its application for a Development Consent Order to the Planning Inspectorate in December 2024.

Please note that these timescales are indicative and may change as the project develops.

National grid launches public consultation

On 21 April, National Grid launched a non-statutory consultation on East Anglia Green Energy Enablement (GREEN) proposals. 

The consultation ran until Friday 16 June.

You can read about the consultation on the National Grid website. Visit nationalgrid.com.

The East Anglia Green Energy Enablement project (East Anglia GREEN) is being developed by National Grid to reinforce the high voltage power network in East Anglia between the existing substations at Norwich Main in Norfolk, Bramford in Suffolk and Tilbury in Essex.

The project will also connect new offshore wind generation to the grid.

The proposals include building a new 400kV overhead line, and underground cable through the Dedhem Vale AONB, work at existing substations and building a new substation in the Tendring district to connect new proposed offshore wind farms to the electricity transmission network.
