If you see a low-flying helicopter moving along the electricity transmission lines, you've likely spotted a chopper on an aerial maintenance check. Each year, helicopters patrol almost 13 000 km of transmission lines and infrastructure that make up TransGrid's network. Teams aboard the choppers look for infrastructure that needs to be repaired, or trees and shrubs in easements that could pose danger in a fire or storm.

Patrols reduce risk in the event of a bushfire or storm
Maintenance patrols are vital for the safety of communities nearby easements, and for the safe and continual supply of electricity across the State.
You likely know that scrub can burn quickly and with devastating impact on a hot, dry day. You may be surprised to learn that a 10 metre tall tree can have a flame height of more than 30 metres in a bushfire. It’s vital that clearance zones are observed in transmission easements.
