It’s important to limit the height and density of vegetation around powerlines to keep them at a safe distance in all conditions.
Near distribution lines
These are the poles and wires you see around the streets or on private properties.
- Plant species with a maximum mature height of 3 meters or less, within 3-7 meters of the powerline.
- Plant larger species more than 7 meters away from the powerline.
- Plant vegetation at a far enough distance that prevents it from falling on the powerlines. For example, plant a tree that can grow 10 meters at least 13 meters from a powerline.
Near transmission lines
These are the big towers that transport high voltage electricity.
Because transmission lines move electricity at very high voltages, they generally run through easements. An easement is an area of land that’s reserved for important infrastructure.
These easements allow us to access the lines and limits what can be planted under and next to the lines. Easements vary in width depending on the voltage they carry.
When planting vegetation on an easement:
- Choose species with a maximum maturity height of 3 meters.
- Scatter or clump trees or shrubs across the easement. Up to 10% of the easement vegetation can be mature trees or shrubs.
- Avoid planting any vegetation within 5 meters of the tower to keep clear access at all times.
- Make sure vegetation doesn’t block vehicle access along the easement.
When planting vegetation next to an easement:
- Make sure vegetation doesn’t block vehicle access or cause a fire risk if it falls onto the easement.
- These requirements may be different in special circumstances, such as in certain terrain like gullies or watercourses. Contact AusNet for guidance.
Best trees to plant
We recommend planting indigenous plants – ones that are naturally found in your area. These plants are ideal as they:
- have adapted to the soils and climate
- have reasonably predictable growth rates
- need less maintenance, like pruning and fertilising
- help prevent soil degradation
- attract native birds, animals, and plants
- help maintain the local ecosystem.
