Beyond the Horizon: How Drones Are Revolutionising National Grid's Inspections
National Grid explains how it uses drones on its England and Wales transmission network. Pilots fly targeted visual-line-of-sight checks, while a centrally controlled autonomous BVLOS system built with sees.ai surveys long stretches of line. The piece also covers thermal hotspot detection, LiDAR/photogrammetry digital twins and confined-space inspection of tunnels and indoor substations.
- BVLOS capability came out of a four-year innovation programme with sees.ai
- Sensors cited: high-resolution cameras, thermal, LiDAR/photogrammetry; confined-space drones for tunnels and indoor substations
⚠ Company's own story; no fleet size, models or measured savings given / BVLOS expansion still depends on evolving CAA regulation; complex work still needs lineworkers

National Grid rolls out automated drone inspections across transmission network
An engineering-institution news item on National Grid launching what it calls the world's first centralised autonomous aerial inspection capability for electricity infrastructure. Drones from Chichester-based Sees.AI fly BVLOS near live pylons and conductors, combining autonomy with pilots in a central control room, after four years of trials.
- Technology supplier: Sees.AI (Chichester, Boeing-backed)
- Based on four years of trials; drones fly dozens of metres above ground near live lines

Drones or Unmanned Aircraft Systems (UAS)
Network Rail's official page on using drones for routine maintenance surveys and post-incident response, such as the Edenbridge landslip. Drones reach roofs, bridges, coastal sites, overhead wires and masts so fewer staff go on the track. Flights remain within visual line of sight; a planned flight management system is meant to enable BVLOS and cut data turnaround.
- Network: about 20,000 miles of track and 30,000 bridges, tunnels and viaducts
- Hundreds of flights per year; max altitude 400 ft
- Current ~10-day turnaround, target same-day (often within an hour)
