The Great Grid Upgrade - Norwich to Tilbury November Update
24 Nov, 2025
Clerk
Norwich to Tilbury is a proposal for a new electricity transmission connection. It will play an important part in connecting low carbon, more affordable electricity from where it is generated to where it is needed.
We're taking to the skies
We’re carrying out drone flyover surveys this week along the Norwich to Tilbury route to gather fresh data. These surveys will give us detailed views of the route to complement the information we already have.
The flights will be carried out by Stirling X, a Norwich-based company with fully certified pilots operating under enhanced permissions from the Civil Aviation Authority (CAA). The drones will fly at around 100 metres (about 400 feet), capturing high-quality video footage to keep our information accurate and up to date.
What you can expect
Our drones will only record footage relevant to the route and surrounding landscape. Each flight is managed by a qualified pilot, supported by trained observers along the route to ensure everything runs smoothly.
We’ll mainly use public rights of way and other accessible areas for take-off and landing, so disruption will be kept to a minimum. We’re also coordinating with local airfields, including Wattisham, to make sure operations are safe.
Noise levels will be very low - similar to an electric lawnmower during take-off and landing - and once the drones reach operational height, you won’t be able to hear them.
Ongoing surveys
We’re continuing vital environmental surveys and assessments along the proposed route. You might see our team out and about as we gather the information needed to shape the next stage of the project.
Surveys are a key part of any major infrastructure development. They help us understand the local environment and prepare detailed construction plans. This work will continue throughout the examination period to ensure everything is accurate and up to date.
