A Hobart power bill can increase because of higher usage, winter heating, changes to rates or your billing period, or an estimated meter reading. Check the bill’s usage in kilowatt-hours, daily supply charge and tariff against an earlier bill, then ask your retailer to explain anything unusual. You can compare available Tasmanian electricity offers through the Australian Government’s Energy Made Easy service, although the cheapest option depends on your circumstances and usage. If you hold a valid concession card, check whether you may qualify for a Tasmanian electricity concession through your retailer or the Tasmanian Government.
