A time of use tariff charges different electricity rates at different times, usually with higher peak prices, lower off-peak prices and sometimes shoulder rates. In Sydney, the times and rates can vary between retailers, electricity networks and plans, so check your retailer’s current fact sheet rather than relying on a general timetable. It may suit households that can run appliances, charge an electric vehicle or use a home battery during cheaper periods, but it could cost more if most usage occurs during peak times. Compare estimated annual costs on the Energy Made Easy website and confirm whether your meter and plan support time-of-use pricing.
