Transgrid helicopter inspection

In preparation for bushfire season, Transgrid has undertaken extensive aerial inspections along 13,000km of transmission lines to ensure its adherence to bushfire mitigation measures.

Transgrid conducted its bushfire safety program from February to November 2022 to ensure safe vegetation clearance and the condition of transmission assets.

The assessments, which included 3D laser scanning, aerial imagery analysis, and helicopter inspections, involved:

  • A fixed wing aircraft 3D laser survey (LiDAR) of easements across the 13,000km network to identify vegetation encroachments. This profile included a minimum statutory safety clearance and a regrowth allowance to ensure optimum safety
  • Helicopter inspections and aerial imagery of 13,000km of the network to physically assess the condition of towers and lines

Transgrid CEO, Brett Redman, said the transmission network provider for New South Wales and the Australian Capital Territory has a comprehensive annual safety program to reduce the risk of bushfires and protect the community.

“These aerial surveys and inspections involved 700 flying hours and have enabled our teams on the ground to proactively respond to addressing potential bushfire hazards.

“Transgrid has reviewed advice from the Bureau of Meteorology, Australasian Fire and Emergency Service Authorities Council and the NSW Rural Fire Service in preparation for the forthcoming bushfire season and will remain in close contact with relevant agencies.

“Through Transgrid’s robust Asset Management System, a great deal of planning, analysis and modelling goes into ensuring that we right-size our program and direct resources to areas of greatest risk and need to maximise effectiveness.

“While we are expecting a lower than average bushfire risk following significant rainfall this year, our extensive pre-summer preparedness will ensure the network is safe for our people and the community.”
