When trees grow into power lines, they can spark fires and cause serious injuries. They also lead to around 1,700 power outages each year, affecting homes, schools, hospitals, and businesses.
With over 110, 000 kilometers of power lines to keep clear – our crews are busy! Find out how we manage trees and power line safety below:
Integrated Vegetation Management
Proactively keeping trees away from power lines.
Request Tree Trimming Assessment
Responding to your concerns and requests for tree trimming.
Prevent Future Outages by Planting in the Right Place
Plant the right tree in the right place to avoid power outages and keep you and your neighbours safe. Before planting, make sure you understand right-of-way (ROW) boundary zones.
Understanding Power Lines and Trees
Transmission Lines: These high-voltage lines carry power over long distances from power stations to substations. They’re usually mounted on tall towers and are less common in residential areas.
No planting is permitted within the ROW for transmission lines. Ensure 15 to 22.5 metres from either side of outermost power line are clear.
Distribution Lines: These lower voltage lines carry power from substations to homes and businesses. They’re typically found on power poles along streets and in neighbourhoods. For distribution lines, consider the tree’s height:
- Clear Zone - 3 metres from either size of outermost power line
- Low Zone - 3 to 6 metres from either side of outermost power line
- Medium Zone - 6 to 15 metres from either size of outermost power line
- Tall Zone - 15 metres and further from either side of outermost power line
What to Plant

- Your local nursery can provide advice on choosing the right tree for the right space.
- You can download our Plant Smart brochure, which explains clearance distances and suggests appropriate tree species.
