Electricity prices in Newcastle vary with your retailer, Ausgrid network area, tariff type, household usage and available discounts, so there is no single average price for every home. Your bill may include a daily supply charge plus a usage rate in cents per kilowatt-hour, with different rates for time-of-use or controlled-load tariffs. Compare current offers using the Australian Government’s Energy Made Easy website, entering your postcode and recent usage details. Check the plan’s estimated annual cost, fees and conditions rather than comparing the usage rate alone.
