UK, England, Norwich: National Grid will soon begin drone surveys along the proposed Norwich to Tilbury electricity route, using aerial technology to capture high-quality footage that will support environmental assessments and engineering design. The surveys aim to reduce the need for ground teams walking the full length of the corridor, minimising disruption to local communities, agricultural land and wildlife habitats.
The inspected flights will be carried out by Stirling X, a Norwich-based operator with enhanced permissions from the Civil Aviation Authority (CAA). Certified pilots will capture video at heights of around 100 m, providing detailed views of terrain, vegetation, watercourses and other features important for planning the project responsibly.
According to National Grid, the drones are strictly configured to record only landscape information relevant to the route. They will not collect personal data or identifiable images of people or property. The approach is designed to ensure surveys remain focused solely on technical and environmental requirements.
The flights will be completed in short sections of 5–10 km, with trained observers monitoring progress from the ground. Drones will not directly fly over residential properties and will produce minimal noise, comparable to an electric lawnmower during take-off and landing before becoming quieter at height.
James Magson, Senior Project Surveyor at National Grid said: “By using this technology, we can reduce the need for teams to walk the entire route on foot, which helps to minimise disruption for local communities, landowners and the environment. This is about working smarter and using innovation to deliver essential energy infrastructure in the most responsible way possible.”
Survey work will start near Norwich and proceed south in phases. The captured data will support design work for Norwich to Tilbury, a key part of The Great Grid Upgrade. The project’s Development Consent Order has been accepted for examination by the Planning Inspectorate, with opportunities for public involvement during the upcoming process.
