Time to trim your trees


On the Orion network, 10-20% of all unplanned power outages are caused by trees — including vegetation — coming into contact with power lines. In storms, trees can cause 80% of outages.

Fire damage to property from branches sparking in dry conditions and serious injury from electrocution from contact with trees touching power lines are also possible consequences of not maintaining your trees.

Stay safe

Before you begin, remember to keep yourself, and those around you, safe.  We do recommend you hire professionals to safely carry out any work that is close to power lines.

If you or someone working for you intends to work within 4 metres of power lines, a close approach consent is required from Orion before you start. As a tree owner, you may be liable for any damage caused by carrying out trimming or felling of trees.

How close is too close?

Trim early – keep branches at least 1.5 metres away from low voltage lines and for high voltage lines please see the Notice zone distances listed below. 

Cut down – consider removing tall trees that could fall through power lines.
