Off-peak refers to lower, discounted electricity prices during specific times. Off-peak times are generally when residential homes and businesses use less electricity. Off-peak times will vary depending on your location and meter type, but typically are at night or weekends. Electricity used in busy peak times can place a strain on Australia’s electricity networks. That’s why off-peak electricity is charged at a cheaper price, to encourage people to use their electricity outside these busy times. Off-peak electricity can also refer to electricity being used by a stand-alone appliance, like an electric hot water service on a dedicated circuit. This appliance is metered separately and can be billed on off-peak rates.
