Essential Energy's Northern regional manager Ben Williams said windy weather could cause trees and branches to fall onto powerlines, often resulting in power supply interruptions.

He urged residents to prepare their homes and surrounds for strong winds.

"We encourage property owners to look up and check that trees, branches and other items are not too close to overhead powerlines as they can be blown into the lines in windy weather," Mr Williams said.

"If you find a tree within close proximity to powerlines, contact Essential Energy to arrange an inspection.

"Do not attempt to prune or remove the trees yourself - tree trimming can be hazardous near overhead powerlines and should only be performed by qualified arborists that are authorised by Essential Energy to perform the work."

He encouraged residents to complete a risk assessment of their surroundings before the windy weather hit.

"We urge householders to clear up their yards, remove loose debris and fasten down items such as trampolines which could be picked up in strong winds and potentially damage powerlines," Mr Williams said.

"Take care while engaging in outdoor activities, such as kite flying, during wild winds and remember to steer clear of overhead powerlines," he said.

If a powerline is brought down, Essential Energy recommends people should remain at least eight metres away from the wires and anything in contact with them.

"Remember that fallen powerlines may be hidden, so look up to see if they are still in the air," Mr Williams said.

Residents who wanted to report a fallen powerline or power supply interruption could contact Essential Energy on 13 20 80.
