What to do in an outage
We do everything possible to keep the power on but sometimes power outages happen. Find out what to expect during an outage and ways to keep yourself, your family or colleagues safe.
Planned outages are needed so we can upgrade the network or perform planned maintenance
Unless it’s an emergency, we'll let you know at least three days before a planned power interruption.
We’ll be in touch through advertising, individual notices, phone, text, email, SMS or letter with the dates and times which might impact you.
Unexpected or unplanned outages can occur for several reasons including:
- Cyclone or storm season
- Severe weather, high winds and lightning strikes
- Animals, such as birds, impacting power lines
- Vegetation or debris impacting power lines
- Damage to electrical infrastructure from vehicle or machinery accidents
- Vandalism
- Pole top fires Bushfires

What to do after a power outage
When your power returns after an outage you may need to:
- Reset some equipment and appliances, such as air conditioners or reticulation timers by following your operating instructions.
- Check your solar system is back on if you have solar panels. Not all solar inverters will switch back on automatically after a power outage.
If your outage was planned, and you find that you have partial or no power after the planned times, check your fuse box to make sure safety switches including RCDs (residual current devices) are all in the 'on' position.
