In Darwin, a time-of-use tariff charges different prices at different times, usually with peak, shoulder and off-peak periods. Power and Water Corporation sets the current tariff structures and time bands, and availability may depend on your meter and property. It could suit households that can shift activities such as hot-water heating, laundry or pool pumping to cheaper periods, but savings are not guaranteed. Check Power and Water’s latest residential tariff schedule and compare it with your interval usage before changing plans.
