Examination update
On 10 August 2026, the Planning Inspectorate closed its examination of Norwich to Tilbury. All documents submitted during the examination remain available on the Planning Inspectorate's website.
The Examining Authority now has three months to prepare a report and recommendation for the Secretary of State, who will decide whether to grant development consent for us to build and operate Norwich to Tilbury. The decision is expected within three months of the recommendation being received.
About Norwich to Tilbury
Norwich to Tilbury is a proposal to build a new 400 kilovolt (kV) electricity transmission connection for 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.
Why we need to build Norwich to Tilbury
It is a key part of The Great Grid Upgrade - the largest overhaul of the electricity grid in generations. It will enable us to carry more home-grown renewable energy from where it is generated to where it is needed, boosting Britain’s energy security.
The existing network in East Anglia does not have the capacity to deliver the required amount of electricity to where it is needed. With demand expected to double by 2050, the Norwich to Tilbury upgrade will provide enough electricity to power up to six million homes and businesses.
What is happening now?
Between 2022 and 2025, we held a series of public consultations on the project, where local communities across East Anglia were able to provide their feedback on our proposals. In August 2025, our DCO application for Norwich to Tilbury was submitted to the Planning Inspectorate. This was accepted by the Planning Inspectorate for examination in September 2025.
The Examining Authority then carried out six months of examination, which closed on 10 August. During the examination, the Examining Authority considered evidence and representations submitted by National Grid, local authorities, statutory bodies, landowners, community groups and members of the public. All documents submitted during the examination remain available on the Planning Inspectorate's website.
The Examining Authority now has three months to prepare a report and recommendation for the Secretary of State, who will decide whether to grant development consent for us to build and operate Norwich to Tilbury. We expect the decision to be made within three months of the Secretary of State receiving the recommendation.
