Vegetation management

Trees, shrubs and other vegetation enhance our lifestyles. However, vegetation touching powerlines is a proven risk to public safety and one of the main causes of power supply problems.

Management and maintenance

Effective management and maintenance of vegetation around powerlines is essential for public safety and reliability of electricity supply. We employ contractors for tree trimming throughout Queensland, the Torres Strait Islands and Northern New South Wales.

Tree trimming is done on a cycle based on plant growth rates. This is predicted using scientific information from satellite imagery, high resolution aerial imagery, and local knowledge.

We have also partnered with Fugro ROAMES to improve the efficiency of our vegetation program. LiDAR technology helps us identify and target vegetation that grows into our clearance profile.

Trimming is carried out by trained professionals in accordance with Australian Standard AS4373 Pruning of Amenity Trees, to ensure we adhere to legislative requirements.

Our Standard for Vegetation Management (below) details how we manage vegetation that may interfere with the operation or safety of our powerlines.

Similarly, our Standard for Vegetation Clearance Profile (also below) details vegetation inspection and treatment requirements to ensure powerline corridors are maintained consistently, based on voltage and where the powerline is located.

Community awareness

Through community awareness programs, powerline friendly trees are now easier to identify and purchase through your local garden nursery.

Many schools have benefited from biodiversity assessments and plantings and most Queensland Local Council areas have recommended species lists for planting near powerlines.

Planting the wrong plant near powerlines may eventually cause an increase to the cost of electricity supply and presents an unnecessary safety risk. It may also increase the damage caused by cyclones and storms.

Research and development

Our vegetation management techniques have benefited from research and development through flora and fauna surveys and raising awareness of endangered and vulnerable species.

We aim to promote low growing species wherever possible, to minimise vegetation impacts to powerlines and maximise biodiversity and habitat retention in powerline easements.
