Power outages and interruptions

Power outages and interruptions

Planned electricity interruptions

As part of our ongoing maintenance and improvement program, Hydro Tasmania may need to occasionally switch off electricity supply to provide safe access to electricity poles and wires in some distribution areas.

Unless it is an emergency, we will give you at least four business days' written notice of the outage occurring.

If there are any planned power supply interruptions for King Island or Flinders Island, these will be listed below:

  • There are no current outages

Information on current outages can also be obtained through the 24 hour call centre on 132 004.

Unplanned electricity interruptions

Unfortunately some power interruptions are unavoidable. These may occur because of:

  • storms,
  • lightening strikes,
  • falling trees or branches,
  • birds or animals contacting power lines,
  • motor vehicle accidents,
  • equipment failure.

Hydro Tasmania will endeavour to restore supply as soon as possible. For information when loss of supply occurs and when supply may be restored, please contact the 24 hour call centre on 132 004.


Customers can help us pin point faults by letting us know if a power interruption is affecting only your property or is more widespread.  Please assist by reporting any faults that you observe in our electricity networks by calling the 24 hour call centre on 132 004.

Life support customers

If you are a customer that relies on medical equipment, we urge you to make sure you have a back-up plan in case of unexpected problems on the electricity network.

It is recommended that you consult and plan with your doctor or other medical service providers where to go in the event of an extended interruption.

How to plan for a power outage:

  • Have a list of emergency numbers readily available (fire fighters, police, ambulance, etc.) as well as the 24 hours call centre on 132 004.
  • Use surge protection for electrical equipment, such as TVs, DVD players and computers.
  • Prepare an emergency kit and keep it close by. It may be essential in the event of a major outage (flashlights, spare batteries, first-aid supplies, bottled water, etc.)
  • Have a backup power supply or a temporary place to stay for anyone who relies on a life-support device.
  • Notify your security company of the interruption to make sure alarms operate correctly without power.

​What to do during a power outage

  • Do not carry out any electrical work.
  • Unplug electrical appliances to avoid the risk of short circuits when power is restored.
  • Avoid opening your refrigerators and freezers. Frozen food can last for 24 hours if the freezer door is left closed. Food in refrigerators can last up to 10 hours.
  • Use a generator with extreme caution. Use generators for power to appliances directly. Do not connect the output to the house switchboard or wiring. This can cause a safety risk for our workers.
  • Leave one light switch on so you will know as soon as power is restored.
  • Make sure your mobile phone is fully charged.

For emergencies, to report a power outage or fault please call the 24 hour call centre on 132 004.
