Your electricity bill cost depends on how much power you use, your retailer’s usage and supply rates, your location, billing period, discounts, and whether you have solar or a concession. Heating, cooling, hot water and other large appliances can significantly increase usage, particularly during extreme weather. Check your bill for the daily supply charge, cents-per-kilowatt-hour rate and any discounts, then compare offers using the Australian Government’s Energy Made Easy website. Your retailer can explain your current plan, while state or territory concessions may be available depending on your circumstances.
