Why networks switch the power off
Most network work can't be done on live equipment safely. Replacing a pole, upgrading a transformer, connecting a new subdivision or clearing trees close to the lines usually means isolating a section of the network. Networks plan these jobs ahead and try to schedule them for times that affect fewer people.

These rules come from rule 90 of the National Energy Retail Rules, which apply in NSW, the ACT, Queensland, South Australia and Tasmania. South Australia and Tasmania allow very short planned interruptions, under 15 minutes, without the usual notice. Victoria, WA and the NT have their own rules, and your network's website explains the notice it gives.
Register life support equipment
If anyone at your address relies on medical equipment that needs power, register it with your retailer. Our guide to medical equipment and electricity explains how.
Getting ready for a planned outage
Check the notice
Note the date and time window. Many networks list planned work on their outage map too.
Charge what you need
Phones, laptops and a torch. Have a battery radio if the outage is long.
Plan for the fridge
Keep it closed. A closed fridge holds its temperature for several hours.
Switch off sensitive gear
Turn off computers and appliances that could be affected when power returns.
See our blackout checklist for food safety times and what to do if the work runs late.
