Ready for take-off: Powercor’s powerline inspections are under way.
Powerline inspections from the air are under way in Shepparton and the surrounding region as part of electricity distributor Powercor’s year-round vegetation inspection and tree-cutting program.

The helicopters are fitted with advanced light detection and ranging technology, known as lidar, to accurately identify the distances of trees to powerlines.
This information is fed back to experienced teams that will cut the vegetation away from powerlines to keep the network and community safe.
The Powercor flights are taking place over more than three weeks, covering Shepparton, Kyabram, Numurkah, Cobram, Yarrawonga, Tatura, Rochester and surrounding areas.
Powercor’s vegetation management program is the largest in the state, inspecting and managing vegetation across more than 70,000km of powerlines and about 570,000 powerline spans through central, northern and western Victoria, including across hazardous bushfire risk areas.
Powercor spokesperson Emma Tyner said the program was a critical part of keeping the network safe and reliable for customers.
“Our work is about reducing the risk of trees and branches coming into contact with powerlines, which can lead to power outages and fires,” she said.
“By inspecting the entire network every year, we are able to determine where and when we need to cut trees and branches away from powerlines.
“On any given day, we have more than 300 people managing vegetation to keep our network safe and reliable.”
Teams attend sites on both private and public property to assess what cutting needs to occur.
If crews are required to cut trees on private property, Powercor will notify customers in advance of any cutting unless the work needs to occur immediately for safety reasons.
“Each year we cut back hundreds of thousands of trees and branches away from powerlines to keep the network safe and reliable,” Ms Tyner said.
“We’re able to use the data from our lidar helicopter scans to form a 3D model of the network, which our teams use to identify trees requiring trimming.”
Weather permitting, the Bell 505 helicopters fly at an altitude of just over 300m, capturing enormous amounts of data to form an accurate image of powerlines across the region.
Collecting data: Data collected from lidar helicopter scans form 3D models of the network to help identify trees requiring trimming. This is Shepparton near Goulburn Valley Health.
