Comparing plans vs comparing tariffs

Your tariff type is a key element that determines the kinds of plans relevant for you. Bill Hero compares between energy plans, not energy tariffs.

There's a lot of confusion about energy plans vs tariffs. Sometimes these terms are used interchangeably, but they mean very different things.

Your tariff type is defined by your distributor, and governs the methods used to charge you for your energy  consumption. Your meter will be configured to record your energy consumption as required by your tariff type.

Ultimately, it is the meter type and configuration that defines the range of available tariffs for your property.

Retailers offer plans specific to each tariff type, so the tariff you're on will then determine the range of plans available to you.

Classes of electricity tariff

There are four main classes of electricity tariff:

  • Single rate tariffs – The price you pay for your energy consumption does not change on basis of time of consumption. Note that under a 'single rate' tariff, it's still possible that the price per kWh may change according to the quantity of kWh consumed – so one price might apply up to a certain kWh threshold, then another price applies beyond that threshold. These kinds of tariffs can also be referred to as block rate or stepped tariffs. Single rate tariffs are still the most common tariff types in Australia. Basic consumption meters can only support Single Rate tariffs since the meter records only cumulative kWh consumption, not the time at which the energy was consumed.
  • Time of Use tariffs – As the name suggest, a Time of Use tariff means that the price per kWh can change according to the time of consumption. Time of Use tariffs include 'Two Rate' tariffs, which have separate pricing for Peak and Off-Peak consumption, and Flexible tariffs which feature separate pricing for Peak, Shoulder and Off-Peak time periods. Time of Use tariffs require a smart meter to be installed, since they require both kWh consumption and time of consumption to be recorded. Distributors set the times for Peak, Off-Peak, and Shoulder periods, however it's possible for a retailer to define their own times independently of the 'official' times set by the distributor.
  • Controlled load tariffs – A controlled load is a separately metered energy supply that is available only at off-peak times. Controlled load is typically used for appliances such as underfloor heating or electric storage hot water systems, where the appliance runs over night. Controlled load is common in settings where there is no smart meter installed, and this tariff type can be viewed as a quasi-time of use tariff since the controlled load energy supply is available only at off-peak times. Some distributors offer two classes of controlled load energy supply - CL1 and CL2. CL1 is the cheapest per kWh, but is available for the most restricted time periods. CL2  costs more than CL1, although it will be less than the single rate price, and is available for a less restricted set up hours.
  • Demand tariffs – Demand tariffs are the newest kind of tariff and are intended to deliver a price signal to encourage energy consumers to minimise peak time consumption, either through shifting their load to shoulder and off-peak times, or by avoiding consumption altogether. Demand tariffs work by applying an additional capacity charge to your bill that scales according to the highest intensity of demand recorded during the 'demand window' time on any day in the billing period. The 'demand window' coincides with Peak hours, and the purpose of demand tariffs is to deliver a financial disincentive for high peak time energy consumption. Demand tariffs require a smart meter to be installed.

Bill Hero determines the tariff type for your energy account from the consumption data presented in your bill, and we compare your bill against other plans available for that tariff type.

Bill Hero does not currently compare between tariff types, so will not make recommendations to switch between tariff types.
