Electricity prices in Sydney depend on your retailer, daily supply charge, usage rates, tariff type and household consumption. Some plans charge different rates by time of day, while others offer a single rate, so the cheapest option depends on when and how much you use electricity. Compare your bill with offers on the Australian Government’s Energy Made Easy website, using your National Metering Identifier and recent usage where available. Check the contract conditions, discounts and estimated annual cost rather than focusing only on the advertised cents-per-kilowatt-hour rate.
