Drone/UAV use and our network

Drone/UAV use near our network

If you’re planning to fly a drone near our power lines or substations, please read these important safety guidelines.

Why it matters

Flying drones close to power lines can be dangerous ⚡

High-voltage power lines create electromagnetic fields that may interfere with your drone’s GPS and compass, affecting flight control. This can lead to collisions with power lines, other objects, or even people. Larger drones can cause more damage if something goes wrong.

Power lines can also be hard to see or judge distance from.

Besides the potential safety risks to the public and surrounding property, your drone could be destroyed and cause a power outage.

Key safety rules

Drones must be at least 4 metres away from Orion power lines at all times.

Flight planning tips

  • Check the area carefully before flying and plan your take-off, flight path, and landing.
  • Avoid flying directly above power lines. If you must, keep altitude high and minimise time overhead.
  • Be aware of other hazards in the area.
  • Check your drone’s return-to-home settings so it won’t fly into power lines.
  • Use tools like AirShare to check airspace and stay compliant.

Operating near or over substations

If your flight path means you will operate near or over substations, please email ✉️ the Orion UAV team and include the following details:

  • Drone type, size, weight
  • Flight plan

We might be able to offer alternative flight paths and give advice on hazards and access if required.

How we use drones to inspect the network

We use Unmanned Aerial Vehicles (UAVs), commonly known as drones, to support day to day work particularly across our rural electricity network. Drones give operators a fast and safe way to inspect lines and assets that can be difficult to reach by vehicle or on foot. By using UAVs, Orion teams can quickly locate and identify faults, helping to reduce outage times and keep the power on for customers, while also minimising safety risks and fatigue for field crews.

Drones have become an important tool for how we improve, monitor and maintain our network. They provide high quality visual data that allows operators to assess the condition of poles, lines and substations without the need for lengthy site visits. In many cases, faults that might have taken hours to find using traditional methods can be identified within minutes using a drone, improving response times and overall network reliability.

We’ve introduced an automated drone-in-a-box solution to monitor our Norwood substation in Selwyn, a pilot programme that showcases how new technology can strengthen the network our communities depend on. Its autonomous inspections give us faster, more detailed insights into the condition of our assets, helping us address issues sooner and improve safety. This trial is an important step toward expanding drone capability across more of our network.
