What to Do During a Power Outage in Australia: Actions From the First Minutes to Restoration

A blackout can last a few minutes or continue through severe weather, heat or network damage. With lights, appliances and internet access interrupted at once, it can be difficult to decide what needs attention first. Use the stages below to organise your response, but act on medical needs or evacuation advice immediately, whatever the elapsed time.

What to Do in the First Five Minutes of a Power Outage

A sudden loss of light can make it hard to judge what has happened. Start your blackout safety check from a safe position. If anyone depends on powered medical or life-support equipment, activate their agreed backup plan immediately rather than waiting for further outage updates.

Check whether the problem is limited to one room, the home or the local network

From a safe position, check whether other rooms and nearby homes still have power. If only one appliance or room is affected, switch the appliance off if safe and avoid repeated resets; contact a licensed electrician if the fault persists. If the whole property is out, check your distributor's outage information to distinguish a network outage from a property fault. If you see fire or another life-threatening danger, keep clear and call triple zero (000).

Stay clear of fallen lines, floodwater and damaged electrical equipment

Treat fallen or low power lines as live and keep well away. Do not approach lines in floodwater, trees or debris, and do not touch damaged switchboards, solar equipment or cables. After storms or bushfires, hazards can remain even when the grid appears off because solar panels and batteries may still be energised. Follow instructions from emergency services and the local network provider.

Use safe lighting and preserve phone battery for essential updates

Use torches or rechargeable lights instead of candles where possible, particularly around children, pets or flammable materials. Reduce phone brightness, disable unnecessary background activity and use low-power mode so the device remains available for outage notices and emergency calls. A small portable power station can keep phones charged and power communications equipment within its rated output. A powered router still needs an operating network connection to provide internet access.

What to Do During the First Hour Without Power

Once you have checked for immediate danger, the next decisions during a power outage depend on who is affected and what needs protecting.

Check the local network provider’s outage information without relying on this article for live status

Your electricity retailer may not operate the local network, so identify the distributor on your bill or ask your retailer. The AER’s distributor guide also lists regional network contacts. Open your distributor’s outage map or official notices and check your address, the affected area and any estimated restoration time. If the outage is not listed, report it through the distributor’s fault service. Check periodically rather than refreshing continuously to conserve phone battery. Follow emergency-service instructions if severe weather affects your area.

Keep fridges and freezers closed and protect temperature-sensitive medicines

Keep refrigerator and freezer doors closed and note when the power failed. The NSW Food Authority gives around four hours of fridge cooling and around 24 hours before a closed freezer defrosts as planning guides. Arrange alternative cold storage early if the outage may continue; an esky with ice bricks can help keep perishable food at 5°C or colder. Check temperature rather than assuming food is safe for the full estimated period.

For refrigerated medicines, check the product’s storage instructions and ask a pharmacist about emergency storage using a cool pack and cooler bricks. Do not freeze medicines. NSW Health advises seeking pharmacist or doctor guidance if storage conditions have been compromised; arrange advice and any replacement supply promptly, especially for essential treatment.

Identify immediate medical, communications and cooling needs

If someone relies on powered medical equipment, put their outage plan into action immediately. Use the backup arrangement agreed with their healthcare team and equipment supplier, and seek help before that backup runs out. Ausgrid’s life-support advice includes an action plan for planned and unexpected outages. Keep a charged phone available to contact help. In extreme heat, close blinds and use the coolest room while checking vulnerable people. Call triple zero (000) for a life-threatening emergency.

Unplug sensitive appliances and avoid switchboard or wiring DIY

Unplug computers, televisions and other sensitive electronics if it is safe to do so, especially when the cause of the outage is unknown. Switch off electric hotplates and ovens so they cannot restart unattended when power returns. Leave one light switched on so you know when supply returns. Do not open the switchboard, alter wiring or build makeshift changeover connections. Grid isolation, generator changeover and fixed backup circuits require compliant equipment and a licensed electrician.

How to Prioritise Power During a Longer Outage

If you are still deciding what to do in a blackout as it continues, look at the demands on your remaining backup energy.

Rank essential devices by safety need, power draw and required run time

Put any medically essential equipment first, using its agreed backup plan. Then rank communications, refrigeration, cooling needed for health and selected lighting ahead of convenience loads. Write down each device’s watts and required operating hours. A home battery backup can support selected circuits when installed for that purpose; check which circuits actually have backup and the battery’s remaining charge before allocating energy.

Estimate energy with watts × hours: an illustrative steady 150 W combined load for eight hours needs 1,200 Wh at the devices. Allow extra battery energy for conversion losses and your chosen reserve. For a cycling fridge, use measured consumption over time rather than assuming it draws its label wattage continuously. Add the essential loads to see whether your remaining energy can cover the planned period.

Reduce non-essential loads and check each backup source’s limits

Turn off unnecessary heaters, cooking appliances and other high-wattage equipment to preserve energy. The BLUETTI Elite 200 V2 provides 2,073.6 Wh of battery capacity and 2,600 W total AC output, making it a practical option for a limited group of plug-in essentials. Check each outlet’s limit, the combined running load and any motor-starting demand. Compare the energy budget above with the available charge, allowing for losses and reserve; remove convenience loads first if the budget falls short.

Use portable generators outdoors and never backfeed a home through a power point

Fuel generators must operate outdoors in a well-ventilated location away from doors, windows and occupied spaces because exhaust contains carbon monoxide. Never use one in a garage or other enclosed area. Follow generator safety guidance for weather protection, suitable leads and cooling the unit before refuelling. Never connect a generator to a household power point to energise the home: backfeeding can expose workers and neighbours to lethal voltage. A fixed generator connection requires an approved changeover arrangement installed by a licensed electrician before use.

Relocate if heat, medical needs or local emergency advice makes staying unsafe

If the home is becoming too hot, essential medical equipment cannot be supported, floodwater is entering the property or authorities recommend evacuation, move to a safer location when it is safe to travel. For heat, Healthdirect suggests a cool public place such as a library or shopping centre; check that it is open and accessible. Take medicines, identification, chargers and essential supplies. Arrange transport or assistance early if someone cannot leave safely on their own.

Keep Essential Devices Powered During a Longer Outage With BLUETTI

If the main challenge is keeping a modest group of essentials running for longer, BLUETTI Elite 300 offers 3,014.4 Wh capacity with 2,400 W continuous AC output. Its larger energy store gives a bigger budget than the earlier 2 kWh example for the same measured load. It is a useful choice when duration matters more than running several high-power appliances together. Match the fridge’s startup demand and the total running load to its output before choosing what to connect.

Where the essential appliances used together need higher AC output, BLUETTI Apex 300 provides 2,764.8 Wh capacity and 3,840 W total AC output, with support for compatible expansion batteries. Choose this route for greater simultaneous power demand, or add compatible battery capacity when the energy budget calls for longer operation. Its base capacity is lower than the 3 kWh option above: choose by both the watts needed at once and the watt-hours needed over time, rather than output alone.

What to Do When Grid Power Returns

The return of electricity does not tell you how stored food or storm-affected equipment has fared. A few checks come before normal use.

Leave sensitive equipment disconnected until supply is stable

Keep sensitive equipment disconnected if the supply is flickering, unusually dim or unusually bright. Only switch off accessible power points and unplug appliances if safe; do not touch the switchboard or metal fixtures when supply is abnormal. Contact the distributor immediately and leave equipment disconnected until the problem has been assessed. If supply returns normally and there is no sign of damage, reconnect sensitive devices after the checks below.

Restart high-load appliances one at a time

Reconnect major loads gradually so the household circuit and any backup transfer system are not hit with several large startup demands at once. Air conditioners, pumps and refrigerators can draw higher power when motors start. If you were using a battery system, allow it to return to its normal charging mode according to the manufacturer's instructions rather than forcing every load and charger on simultaneously.

Check food, medicine and electrical equipment before normal use

Check whether perishable chilled food remained at a safe temperature. A closed refrigerator generally keeps food cold for around four hours, but food safety depends on its actual time and temperature history. NSW Food Authority advises avoiding refrigerated food that has been allowed to warm for two hours or more. Follow your state food authority's power-outage guidance, discard food if its safe storage history cannot be established, and never taste food to test its safety. Do not refreeze fully thawed food.

Ask a pharmacist about refrigerated medicine if storage conditions were outside the required range. Check appliances for water exposure, burning smells or visible damage before use. Equipment affected by floodwater, fire or wiring damage should be inspected by a licensed electrician before normal use.

Conclusion

Knowing what to do during a power outage helps you act in the right order: avoid electrical hazards, address urgent health needs, check the outage and protect communications, food and medicines. Use your essential-load budget to conserve backup energy, and leave early if staying becomes unsafe. When supply returns, check food and equipment before resuming normal use. Afterward, replenish supplies and update your outage plan with anything the blackout revealed.
