Ask your retailer whether you have an off-peak or controlled-load tariff and which hours apply, as times and pricing vary by state, network and plan. Run eligible appliances such as hot-water systems, dishwashers and washing machines during those periods where practical, using timers only if the appliance and wiring are suitable. Check your bill to confirm the off-peak rate is actually cheaper overall, including any supply charges or peak-rate increases. Your retailer or a licensed electrician can explain your meter setup and whether changing plans or controls is appropriate.
