Public consultation and programme

We are consulting on our proposals for Norwich to Tilbury, which include:

• the preferred draft alignment for a new 400 kilovolts (kV) electricity transmission connection of around 184 kilometres (km) running from Norwich Main Substation to Tilbury Substation via Bramford Substation including approximately 159 km of new overhead line and approximately 25 km of underground cabling
• six new Cable Sealing End (CSE) compounds (where high-voltage underground cables join onto an overhead line) and associated permanent accesses
• a new East Anglia Connection Node (EACN) 400 kV substation, which would connect clean energy from offshore wind generation to the energy network so the energy can reach homes and businesses where it’s needed.
• an alternative design at Waveney Valley, substituting approximately 2 km of pylons with underground cabling
• substation extension works at the existing Norwich Main, and Bramford substations and works within the existing Tilbury Substation
• temporary works including access roads, tracks, compounds and associated with the project’s construction.

We are also consulting on the preliminary findings from our environmental studies and assessments as well as proposed mitigation for any potential impacts to the local environment, including animal habitats and the local landscape.
 

Temporary construction requirements

Building the project would involve a range of temporary construction activities. These would include preparing land and creating temporary haul roads to access work areas as well as providing temporary areas to store materials, vehicles and staff welfare facilities. Our red line boundary – the geographic extent of the project as shown on our interactive map and plans – includes the areas proposed for construction. We welcome views and comments as part of this consultation. 
 

Waveney Valley

In response to feedback from our previous consultation, we are consulting on proposals for an alternative design (in addition to proposals for an overhead line) at Waveney Valley. 

This alternative design would include the installation of approximately 2 km of underground cabling (and the substitution of 2 km of overhead lines from our proposals) and two CSE compounds (to join the high-voltage underground cables onto the overhead line) with associated access roads. This would increase the number of CSE compounds from six to eight. While underground cabling would reduce landscape, communal outdoor spaces such as parks and playgrounds and places of historical interest and importance in the area, it would have an impact on ecology, archaeology and peat soils, and come at an additional cost. 

We welcome feedback on both of the proposals at this consultation.
 

Taking part

During statutory consultation, we’re holding a series of public information events and webinars. You can find out how you can attend these below. We have also published detailed information on our project.

You can see all our consultation materials on this website within our document library. You can also explore our proposals in detail via our interactive project map. Paper copies of documents will be available to view at public information events and a selection can be found at inspection points, which are public places anyone can access outside of consultation events where they can inspect project documents. A list of these locations can be found below.

We want to hear your views, you can provide feedback by: 

• completing the online feedback questionnaire here
• emailing your comments to: [email protected]  
• posting your written responses (no stamp required) to: FREEPOST N TO T  
• completing a paper feedback questionnaire and return it using the freepost address. 

You can pick up paper copies of our feedback questionnaires at our public information events or at the inspection points listed below. You can also request a copy by calling us on 0800 915 2497. 

We have produced an interactive Project map detailing our proposals for Norwich to Tilbury. This is to make it easier to identify which area is most relevant to you.  
 

Public information events 

Throughout the consultation we are holding a series of face-to-face events. Our public information events are being held across the local area. Information about our proposals will be on display, including our interactive map, as well as copies of maps and technical documents. Members of the project team will be available to talk through our proposals and answer any questions. 

Please note that some of the venues may be busy at peak times. Larger venues are marked with an * where there will be more room to view project materials and digital information.  
 

Webinars 

You can attend one of our six online webinar sessions, where we will present details of our proposals and you can ask the team questions. To sign up, pick your preferred webinar in the table below and click the link to register.  

If you require further assistance on how to sign up for a webinar (using the software ‘MS Teams Webinar’), please contact the Community Relations team by phone on 0800 915 2497 or email at [email protected].
  

  * A British Sign Language interpreter will be available.

Inspection points  

Paper copies of the consultation newsletter and feedback questionnaire are available to collect from one of the following local inspection points. These are located within or in close proximity to the emerging preferred corridor and can be collected from the start of and throughout the consultation period.  

Reference copies of the 2024 Project Background Document and the Non-Technical Summary (NTS) of the Preliminary Environmental Impact Report (PEIR) are also available at the inspection points.  

Inspection point opening hours can be subject to change. Please check with the relevant venue for the most up to date opening hours. If you require access to the library during unstaffed hours, you will need to use your library card to enter the building.
