Power outages

Understand how to prepare for, manage, and recover from power outages.

Australia’s power supply works fine most of the time. But our changing climate threatens this system.

What causes power outages

Damage from natural hazards often leads to power outages. Common hazards include:

  • bushfires
  • floods
  • storms
  • cyclones
  • extreme heat.

Power outages can also happen when the demand for electricity is high. This causes the network to overload and the power to go out.

Impacts and effects

Power outages can cause:

  • services like phone lines, businesses, and public transport to stop working
  • food, water and medicines to become unsafe
  • critical medical equipment to fail.

When the power goes out, solar inverters stop working. This stops electricity flowing back into the grid. The technicians can then safely fix the grid. If you have a battery, the power may stay on.

Who is most at risk

If you use a medical device that needs power, it won’t work during a power outage. To stay safe, tell your electric company about your medical device.

Some medicines need cold storage. They might not stay safe during a power outage.

Before a power outage

Be informed

Speak with your doctor about what could happen if you lose power. This could include problems with medical equipment and medicines.
