Natural gas rates and charges
How will my natural gas consumption be measured?
Your natural gas consumption will be calculated in joules – the basic unit of energy used in the natural gas industry.
- 1 mega-joule (MJ) = 1 million joules.
- 1 giga-joule (GJ) = 1000 mega-joules.
The meter on your property will measure the flow of natural gas from the main pipeline in the street into your home.
Your gas account will show your natural gas consumption in MJs.

How does this compare to my current energy use?
Please note: This is a guide only and will depend on the appliances that you choose. For example, natural gas appliances have an average efficiency rate of 80% compared to some electrical appliances (such as heat pumps) that can have an efficiency rate of 300%. That is, for every 1 kWh of energy that is used, you will get the equivalent of 3 kWh of energy.

The above table is to be used as a guide only based on 60m2 or 6.5 squares. Costs may vary depending on room size, insulation, heat-loss, the actual heater and usage.
- Service charges and metre costs are not included. Electrical heating prices are based on Aurora Tariffs – Aurora Heating Discount, residential rates – Tariff 31 and Tariff 61 as at July 2009. Aurora natural gas prices current as at January 2010. LPG cylinder price $112.50 calculated at 16 February 2009. Oil prices are based on current heating oil prices in Hobart, 16 February 2009, of $1.57 per litre. Wood cost at $140 per tonne, based on average advertised newspaper prices in Hobart, February 2009.
- Different models will have different rates of efficiency.
- Unflued heaters, which are not recommended by Aurora, can have an efficiency rating of 90 per cent. Flued gas heaters have efficiency ratings that vary from 60–90 per cent. Flame-effect heaters can have an efficiency rating as low as 50 per cent.
- OffPeak heating is on for a set period during the overnight/afternoon OffPeak times and offer 24-hour heating. Prices are based on Aurora’s Tariff 61.
- Over winter, stay-at-home couples like to heat their home from early in the morning, turning on at 7am and switching off just before they go to bed at 11pm (16 hours total). To enable this, a woodheater needs to be left on for 24 hours. OffPeak heating can be on for a maximum of 10–12 hours.
- Over winter, working couples rarely turn the heater on before going to work. After work they go home and the heater stays on till they go to bed at 11pm. To enable this a woodheater needs to be left on for at least six hours. OffPeak heating can be on for a maximum of 10–12 hours.
- Running costs for ceiling heat at 18°C.
