Your electricity bill usually includes a usage rate, charged in cents per kilowatt-hour (kWh), plus a daily supply charge for being connected. The total also depends on your tariff, such as a flat rate, time-of-use pricing or a controlled load, and may include discounts, fees and GST. Compare plans using the estimated annual cost for your postcode and household, rather than focusing only on the advertised cents-per-kWh rate. Energy Made Easy, the Australian Government comparison site, can help you check available offers and expected costs.
