The work is being undertaken in light of the "devastating" fires in 2019 and 2020.

Higher quality capture using an autonomous image capture sensor means more images can be taken along a more direct and higher flightpath than in previous years. Previously the helicopter had to fly low and frequently over some powerlines to get the same quality.

"The newer technology will not only mean a faster delivery of the images but also lessen the impact on people and livestock in the flight path," operations manager South Eastern, Darren Basterfield, said.

"These flights are a crucial part of our broader program to understand the condition of the network so we can identify and repair damaged or deteriorating network assets according to the risk they present."

The helicopter will be used to fly the powerlines in some southern tablelands local government areas.

"Our overall Bushfire Risk Management Plan involves this helicopter-led data capture, other aerial inspections, drone and ground-based asset inspections combined with our network analysis, to understand and manage risk to ensure the safety and reliability of the network," Mr Basterfield said.

If the inspections identify an issue with the Essential Energy network, the network will be repaired according to the risk to network reliability and community safety.

Weather permitting, the patrols will take place in early September.
