A time of use tariff is an electricity pricing structure where rates vary depending on the time of day. In Perth, these tariffs typically feature lower rates during off-peak hours and higher rates during peak times. This system encourages users to consume electricity when demand is lower, potentially saving on bills. To know if a time of use tariff suits your lifestyle, consider your energy usage patterns and check with your retailer for specific details and pricing.
