A time of use tariff charges different rates depending on when you use electricity, commonly separating peak, shoulder and off-peak periods. In Brisbane, the exact times and prices depend on your retailer, plan and meter, and may reflect the Energex network’s tariff structure. It could reduce your bill if you can shift usage, such as laundry, dishwashing or electric-vehicle charging, to cheaper periods, but higher peak rates may outweigh the savings for some households. Check the plan’s fact sheet and compare estimated annual costs through Energy Made Easy before switching.
