Brownouts

A brownout is a drop in voltage in the electricity supply network. They can be caused by high electricity demand, severe weather or faults in the electricity distribution network.

Did you know?

The term ‘brownout’ comes from the dimming of incandescent lighting when the voltage reduces.


What can happen during a brownout?

During a brownout you may notice that your lights are flickering or your electrical appliances aren’t working properly.

Brownouts can damage some electrical equipment, including fridges, freezers and washing machines. During a brownout or power outage, we recommend turning these appliances off – or turning the power off at the wall.

During a brownout, where possible, try to avoid using high power consumption appliances like kettles, toasters, electric heaters and air conditioners. Speak to a registered electrician about how to protect your home or business from brownouts or power surges.
