TransGrid will be launching helicopters over Yass in the coming weeks to check the condition of towers and power lines and their threat to bush fires.
"These annual safety inspections are an important part of our comprehensive maintenance program to ensure the transmission network is safe for the community and our staff," TransGrid customer engagement manager Darren Clarke said.
A specialist team will inspect more than 13,000 kilometres of transmission line and infrastructure across TransGrid's state-wide network.
The patrols identify vegetation encroachments along transmission line easements and check infrastructure for any maintenance issues.
"Residents across the region may see low-flying helicopters moving along our transmission lines," Mr Clarke said.
"We would like to thank the community for their understanding as we carry out our inspection program and remind the public to exercise caution around transmission lines and towers."
