Flood safety

Electricity and water are a dangerous and potentially fatal combination.

If flooding or unusually heavy rainfall is affecting your community, then it can also inundate our electrical infrastructure.

This infrastructure is located close to the communities we serve so is subject to the same risk of flooding as your community.

We advise people to follow three important steps to be prepared:

1. Be Safe. Your health and safety is the priority.
2. Be Smart. If the power goes out, you’ll want to stay connected.
3. Be Ready. Have a plan in place for back-up power.

But if heavy rain or flooding is forecast, then follow these tips to know what to do immediately before, during and after the event.

Before the flood

• Turn off and disconnect all electrical appliances from electrical outlets.
• Lift all electrical appliances as high as possible.
• If you have rooftop solar, then turn off the system at the inverter and at the switchboard. Turn off any associated battery too.
• Turn off your electricity switches and the main switch at the meter box.
• If you choose to stay in the property, be aware you may lose power, even if your home or business isn’t affected by water.
• Check your emergency plan and kit.

During a flood

• Do not use wet or damaged electrical appliances.
• Do not stay in a building that is flooded when the power is connected.
• Stay at least 150 metres away from submerged power poles or other flooded electrical infrastructure. Electricity can travel through water and can cause serious injury.
• Beware of fallen powerlines and anything in contact with them. Call us to report it immediately on 13 24 12.
• If you receive a shock or tingling sensation from any electrical appliances, plumbing, metal, sink or bath, then avoid all contact with these objects and call us to report the problem on 13 24 12.

After a flood

• If you have evacuated, then check emergency services information to see if it is safe to return.
• Check our outage map for the estimated time for power will be back on.
• If water entered your property then:
  • Do not operate electrical appliances or switch on the power.
  • Do not plug in or use any appliances that have been in flood water until they have been checked by a licensed electrician.
  • You will need to contact a licensed electrician to check and reconnect your electricity safely.
• If water did not enter your property then:
  • Be careful and make sure it is safe before turning your switchboard back on.
  • If any switches do not turn on, or automatically shut off, this indicates the wiring may be affected.
  • You’ll need a licensed electrician to test wiring and appliances.
• Wear synthetic or rubber-soled shoes if water is still around.
• If you have rooftop solar or a battery, then contact your installer or a licensed electrician to check the condition of these devices before turning the system on.
• If you’re using a generator for back-up power, do not attempt to connect it to the wiring of your home. Use it outside with an extension cord to power appliances like a fridge, directly.

Remember that water can damage your electrical installation and wiring. Even once flood waters subside, mud and debris can conduct electricity. This makes your property and surrounding area highly dangerous. So be cautious.

Network response

• We’ve built levees surrounding some of our major infrastructure servicing communities (known as zone substations) to protect them against 1 in 100-year or 200-year flood events depending on the location.
• We monitor weather closely including flood forecasts and water levels.
• We may reduce field work leading up to the event so crews are fresh and able to be called in at all hours.
• Resources including field crews, network operators, Customer Service Agents and equipment are on stand-by for immediate response.
• If flood waters are at risk of breaching our flood defences, then we may need to turn off our zone substations in the interests of community safety. This also prevents important equipment being damaged, reducing the risk of longer outages and helping us respond faster when the flood waters have reduced.
• We’ll coordinate with other emergency services for directions to ensure it is safe for our crews to travel into flood affected areas and to respond.
• Our focus will be on reducing the number of customers affected and restoring power as quickly and safely as possible.
• We’ll send messages to customers via SMS if there is a power outage and including an estimated time of restoration. Initially, this estimate is dependent on a full site assessment by our crews.
• We’ll keep our outage map and current outage lists up to date.
