Locals may notice helicopters flying low over the Bellarine, Surf Coast and areas of the Golden Plains Shire over the next three weeks.
However they are being assured there is no need for alarm.
Powercor is holding its annual vegetation and bushfire mitigation program, using technology to scan the distance between powerlines and tree branches.
The company says the data helps inform it what vegetation needs to be cut.
Ayce Cordy from Powercor said it was important to get accurate measurements.
“Inspecting and managing vegetation growing near powerlines is an essential part of how we keep power safe and reliable for our customers,” he said.
“By capturing data every year, we can track growth rates of vegetation across our network, helping us plan where to cut right now and when we may need to conduct cutting in the future.”
Powerlines around Geelong’s urban areas will be scanned later in the year.
