Perth households may be able to choose a time-of-use electricity plan, depending on their retailer, meter and eligibility. These plans charge different rates at different times, so using appliances during cheaper periods can help, while usage during peak periods may cost more. Synergy offers time-based options for some eligible customers, but plan names, rates and conditions can change. Compare the current offer with your usage history and confirm eligibility and estimated costs directly with the retailer or through Energy Made Easy.
