The price on an Australian electricity bill usually combines a usage charge, measured in cents per kilowatt-hour, with a daily supply charge, and may vary by time of use or controlled load. Your retailer’s rate reflects wholesale electricity, network costs, government schemes, operating costs and GST, although these amounts differ by state, distributor and plan. A bill can also include solar feed-in credits, concessions, late fees or other adjustments, so the headline rate is not the whole cost. Compare the plan’s estimated annual cost, tariffs and fees on Energy Made Easy or with your retailer, using your own usage where possible.
