Why the power goes out

Power outages can happen for a number of reasons including equipment faults, network improvements and emergency maintenance, load shedding and electrical faults at your home or business. 

We routinely inspect and maintain our network, however power outages can still occur. Some of the main reasons are listed below.

Network damage

Powerlines can be damaged by fallen trees, high winds, birds, bats, lightning strikes, car accidents, vandalism and fires. Prolonged heavy rain and local flooding may also affect trees, poles and underground cables. If you see fallen or damaged powerlines, for your own safety treat fallen wires as live, and stay at least 8 metres or 2 car lengths away. Report dangerous poles and wires to us on 13 13 88.

Emergency repairs

Sometimes we may need to switch off the power to parts of the network so our crews can work safely while making emergency repairs. We have plans in place to advise how we operate during these situations. A full description of the objectives for our electricity network and supply to customers is provided in NS238 - Supply Quality.

Equipment faults

We routinely inspect and maintain equipment, however equipment faults can occur causing localised power outages.

Sometimes the electrical fault may be at your home or business. In this instance you will need to engage a suitably qualified electrical professional to check and and make repairs.

Improving network reliability

To ensure we supply your electricity to a safe standard, our equipment must be maintained or replaced from time to time. If the power supply needs to be temporarily interrupted we will keep the period of interruption as short as possible.

If you need to ensure a continual supply (such as customers using life support equipment or businesses which incur exceptionally high costs if interrupted), please contact us on 13 13 65.

Load shedding

On rare occasions we may need to conduct load shedding - a coordinated network outage across multiple areas. Find out more.
