Targeted consultations
In August 2025, we submitted our Development Consent Order (DCO) application, which was accepted for examination in September 2025.
We will shortly be inviting feedback on two minor local changes: near Bulphan, involving third-party access and works, and near Little Bromley, relating to East Anglia Connection Node (EACN) access.
We will publish more information when we open the consultation, which will run from 12 noon Monday 19 January to 11:59pm Monday 23 February 2026. We have also published a notice in local and national papers which is available to view here.

Our proposals
Norwich to Tilbury is a proposal to build a new 400 kilovolt electricity transmission connection of approximately 180 kilometres from the Norwich Main substation via Bramford substation, a new East Anglia Connection Node (EACN) Substation and a new Tilbury North Substation.
Our proposals include:
- approximately 159 km of new overhead line supported on approximately 509 steel lattice pylons
- approximately 21 km of 400 kV underground cabling some of which is located through the Dedham Vale National Landscape (formerly known as Dedham Vale AONB)
- seven new CSE compounds, each with a permanent access, to connect the overhead lines to the underground cables
- a new 400 kV East Anglia Connection Node (“EACN”) substation, with a new permanent access, on the Tendring Peninsula
- a new 400 kV Tilbury North Substation to the south of Orsett Golf Course in Thurrock with access options
- modifications to the existing National Grid Electricity Transmission overhead lines, including into and out of the new 400 kV Tilbury North and access options
- substation extension works at the existing Norwich Main and Bramford substations to connect and support operation of the new transmission connection
- temporary works associated with the construction of the Project.
