WIND WARNING AND OUTAGES - updated 5:00pm

We are experiencing multiple outages across the network. Our crews are working to restore power as quickly and safely as possible. However, the weather conditions and access issues are limiting our efforts.

If you are currently without power, please activate your No Power Plan and prepare to be without power overnight.

Unless there are significant developments, we will provide a further update tomorrow (24/10) at 10am, with details on what areas we will be targeting for power restoration.  

TREAT ALL POWER LINES AS LIVE AT ALL TIMES. Our crews will be repairing and restoring when it is safe to do so. Please stay away from any downed lines and report any sighting to us on 0800 30 90 80.

Medically dependent customers should ensure their power retailer has their most current information, have spoken to their medical professional and are prepared to relocate if needed.

For the most recent updates on outrages, please check our outage map. To report an outage, call 0800 30 90 80.

We appreciate your understanding and patience during this time.

We are completing repairs in the area and are hoping to restore power to the Hanmer Springs CBD this evening (ETA 9pm), unless we find any additional damage.

We are scoping the rest of Hanmer Springs for damage and will provide an ETA for full restoration to the area once known.
