Our proposals and next steps

Our public statutory consultation is now closed. Thank you to everyone who took part, attended our events and submitted their feedback. 

Between Wednesday 10 April and Friday 26 July 2024, we held a statutory public consultation on proposals for Norwich to Tilbury, a new high voltage power network in East Anglia connecting new offshore wind generation and existing substations at Norwich Main in Norfolk, Bramford in Suffolk, and Tilbury in Essex.

During consultation we asked for feedback and comments on our proposals for Norwich to Tilbury, which included:

• 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 also consulted on the preliminary findings from our environmental studies, assessments and proposed mitigation for any potential impacts to the local environment, including animal habitats and the local landscape. 

In June, we extended our statutory consultation to Friday 26 July. We did this to provide people with additional time to have their say and provide their feedback on our proposals after the General Election, which was held on Thursday 4 July. As part of this, we rescheduled some of our webinar events until later in July. You can view those recordings here.
