Some Cairns households may be offered a time-of-use tariff, depending on their retailer, electricity plan, meter and local network arrangements. These tariffs charge different rates at set times, so savings may be possible if you can shift usage, such as pool pumps, hot-water systems or laundry, to cheaper periods. Peak, shoulder and off-peak times and rates vary between plans, and a smart meter may be required. Check your current bill and the retailer’s Energy Price Fact Sheet, then compare the estimated annual cost with your existing tariff before switching.
