Consultation and next steps

Our public consultation runs from Thursday 21 April to Thursday 16 June 2022. This is an important opportunity for you to have your say on our early proposals for East Anglia GREEN with will reinforce the high voltage electricity transmission network from Norwich Main Substation in Norfolk to Bramford substation in Suffolk, on to Tilbury substation in Essex as well as a proposed connection substation to connect new offshore wind generation. 

Have your say on our proposals

To help guide you feedback during this public consultation, we have divided the project into seven sections based on local authorities. This is to make it easier to identify which section is most relevant to you and to provide feedback as required. The below table details what is covered in each section of the proposed route. 

Section Section detail 
Our proposals in South Norfolk (including Norwich substation) This section details our proposed route for a new 400 kV overhead line along with our proposed work to the existing Norwich Main substation.
Our proposals in Mid Suffolk (including Babergh North or Substation) The section coves the Mid Suffolk locals authority area along with parts of the Babergh local authority area to the north of the Bramford Substation. Also included within this section are our proposals for work at the existing Bramford substation. 
Our proposals in Babergh, Tendring and Colchester  Covering the Babergh, Tendring and Colchester local authority areas, the section includes details of our proposed works around the Dedham Vale AONB along with the preferred connection substation.
Our proposals in Braintree Details of our proposed route for a new 400 kV overhead line running through the south of the Braintree local authority area to the north of Witham. 
Our proposals in Chelmsford Our proposals for a new 400 kV overhead line running through the Chelmsford local authority area, running around the western side of Chelmsford from the north east.
Our proposals in Basildon and Brentwood Our proposed route for a new 400 kV overhead line running through the Basildon and Brentwood local authority areas. 
Our proposals in Thurrock (including Tilbury substation) The southern most part of our proposals for East Anglia GREEN, this section detailed our preferred corridor in the Thurrock area along with details of associated works that would need to be carried out at the existing Tilbury substation. 

Our commitment to you

As we upgrade the electricity transmission network and develop proposals to allow more energy to flow on our network, we will work with a wide range of stakeholders and experts.

Listening to communities gives us valuable feedback and insight as we develop our proposals and look to minimise any impacts.

Your views are important to us and we will carefully consider all feedback we receive. It will help shape our plans as our infrastructure projects develop.

Where our plans affect you or your community, we encourage you to let us know your opinions on our proposals.

Our approach to public consultation

Certain types of energy infrastructure fall within the classification of NSIPs, which require a DCO under the Planning Act 2008.

For National Grid, NSIPs include new overhead lines. Applications for DCOs are submitted to and examined by the Planning Inspectorate. They are determined by the Secretary of State for Business, Energy and Industrial Strategy (BEIS), not by a local planning authority, who remain an important consultee in the process. The East Anglia GREEN project falls into this category.

Consultation to support our DCO application is planned to take place over two stages this year and next. This first stage of public consultation is being held at an early stage of development to introduce the project and ensure we capture the views and knowledge of local people before developing our plans further.

The aim of this consultation

The aim of this public consultation is to: 

  • introduce and provide an overview of the project to the public
  • explain why we need to build the reinforcement
  • set out options that have been considered and how we made the decision on the preferred corridor and graduated swathe being proposed
  • present and explain our preferred corridor with graduated swathe
  • present and explain our preferred substation site
  • ensure all stakeholders have the opportunity to provide feedback on our work to date
  • outline next steps and programme and how we will further develop our proposals.

We are using a blend of both traditional and digital consultation tools to reach the widest possible audience. Information about our proposals and access to the project team will be equally available both online and offline.

We are committed to engaging with all stakeholders and we recognise that some people have particular needs or may not have access to the internet.

Our consultation has been designed to ensure we understand these different needs and are accessible to everyone. If you or anyone you know has difficulty accessing project information or providing feedback, please contact us. We want to make our consultation as inclusive as possible, and our community relations team will be pleased to try and help.

Who are we consulting?

Our consultation is open to anyone who may have an interest in our proposals.

We are consulting with residents, communities, landowners, local businesses and interest groups, as well as elected representatives and prescribed consultees, such as the Environment Agency, Natural England and Historic England.

During the consultation we will reach out to hard to reach groups, including younger people, time-constrained people, and those groups identified in discussions with local authorities.

What information is available?

We have published the below materials to provide information on our proposals.

Project Background DocumentProviding an overview of the project and detailing our proposals and how we are consulting.
Corridor Preliminary Routeing and Substation Siting reportProviding more technical information on the project and the need for the project, the options considered, the routing and siting options assessed and our preferred options.
Overview map and individual route section mapsShowing the location of the preferred route and the graduated swathe.
NewsletterSummarising details of the project and public consultation.
Feedback formTo gather comments and feedback.
WebsiteHosting all project information, including downloadable versions of all the above documents, FAQs, an online feedback form and interactive map.

In addition to providing detail maps of each section, which can be viewed on the dedicated section page of this website, we have also produced an interactive map to make it as easy as possible for you to identify issues that are most relevant to you.

Paper copies of the newsletter and feedback form are available at information points along the route for collection, as well as on this website. The locations of these are shown on our project website or you can contact us for this information.

We are committed to making project information accessible to all users. If you need any information or documents in an alternative format such as large print, Braille or audio tape or if you would like a paper copy of any of our consultation or technical documents, please get in touch.

What are we asking for feedback on?

In our project background document and throughout this website we have explained the need case for East Anglia GREEN and our approach to routeing and siting. We want to know your views on our approach, our preferred corridor and graduated swathe, and the proposed substation site. Along with any aspects of the routeing and mitigation that you would like to see in relation to our proposals through the AONB.

We are asking for your local knowledge on the most appropriate location within the swathe to route the pylons and associated infrastructure and if there is anything we should consider as we develop our proposals further.

We also want to know about any concerns or questions you might have about our proposals, or any local factors we should consider.

The feedback received through this first consultation stage will inform how we develop East Anglia GREEN.

Next steps

The feedback received throughout the first stage of consultation will inform how East Anglia GREEN is developed further and will influence the next stage in the design of the project.

Indicative timeline for East Anglia GREEN


Over the coming months we will be in discussions with landowners and people with an interest in land which interacts with the project.

We’ll also carry out environmental impact assessment work and undertake surveys along the route. We will discuss with local authorities what we need to consider as part of these formal environmental assessments and this will be set out within a scoping document.

The findings of our assessments will be detailed in a Preliminary Environmental Information Report which will be presented at the next stage of consultation.

When the non-statutory consultation closes, we will review all the responses as we continue to develop the designs.

Our next stage of consultation is planned for in 2023, when we will present more detailed proposals and the findings from this consultation. At that point people will be able to see how we have taken their views into account, and provide further feedback on the project, which will help us further refine the project design.

Following further project design, the East Anglia GREEN DCO application, including a Consultation Report to show how we have taken your views into consideration, would be submitted and examined by the Planning Inspectorate who would make a recommendation on the application to the Secretary of State for BEIS. The Secretary of State makes the final decision on a DCO application.
