The helicopter inspections across Canberra for 2017 have finished. We would like to thank the community for its patience.

Annual helicopter patrols help keep ActewAGL’s electricity network one of the most reliable in the country. Helicopters fly as part of our network maintenance and essential bushfire mitigation program.

The patrols cover roughly 2,400km of overhead powerlines, saving time and resources to inspect vegetation around poles and wires.

In suburban areas, the helicopters fly around 310 metres above the ground in order to survey the network and use Light Detection and Ranging (LiDAR) technology to determine the distance between powerlines and trees. In rural areas, the helicopters fly 110 to 150 metres.
