From 1 December 2017, smart meters are the standard new or replacement electricity meter. Once you have a smart meter you’ll be placed on a new tariff for your electricity usage. This means you may be charged differently for the electricity you use. We’ve outlined the different tariffs and what they mean for you.

Demand tariff

Demand tariffs are designed encourage you to limit your electricity usage at peak times, when demand for electricity is at its highest. The plan can be compared to booking flight tickets: if you book flights over the Christmas period, you can expect to pay more than if you were to book a flight in September because of the higher demand. Similarly, if you use electricity during peak periods you will be charged a demand rate.

The demand tariff is made up of three charges – a standard supply charge, a usage charge, and a “demand” charge:

1. Supply charge (cents per day)
This charge is a fixed price per day for the supply of electricity to your premises.
138.622c (inc. GST)*
2. Usage charge (cents per kWh)
This is based on how much electricity you use (that is, cents per kilowatt hour).
19.459c (inc. GST)*
3. Demand charge (cents per kW per day)
If you use electricity between 5pm and 8pm AEST, you will pay a demand charge.
This charge is calculated using your highest electricity usage incurred within a
30 minute interval during that period.
15.616c (Inc. GST)*

How the monthly demand charge is calculated

In addition to your normal supply and usage charges, you will be charged a demand charge for electricity that’s used during the maximum demand period. Maximum demand refers to the highest amount of electricity that you’ve used in a half hour interval between 5pm and 8pm (AEST) on any given day in a month. The amount will be calculated as follows:

Your Maximum Demand (incurred within a half hour period and measured in kilowatts (kW))
Demand Charge Rate
(rates are set out in ActewAGL’s schedule of charges)
The number of days in the month.
= Monthly Demand Charge

If, for example, a household switches on a number of their electrical appliances at the same time at 6pm (that is, within peak time) on one evening and they use 4kW of electricity which is their maximum demand on this particular day and the highest for the month, their maximum demand charge for that month will be:

Maximum Demand: 4kW
Demand Charge Rate
: 15.616c (inc. GST)*
Number of days in the month
: 30 days
Demand Charge
: $18.74

The maximum demand resets each month and you only need to reach your maximum half-hourly usage once a month for the demand charge to apply to the entire month. For quarterly bills, you will find three demand charges, one for each calendar month, within the billing period.

Please note – these times are Australian Eastern Standard Time (AEST), which means during daylight savings the time on your meter will display AEST.

Tips for using a demand tariff

  • Try to avoid running numerous electrical appliances at the same time during the peak times.
  • If possible, use appliances outside the peak times when demand is not charged.
  • If you have alternative energy sources, like gas for cooking, use these instead of electrical appliances.


Time-of-use (TOU) tariffs are designed to encourage you to shift your electricity usage to different times of the day. You will be charged at different rates for using electricity at the different times. The cost of electricity is at the highest during peak periods (for example, early in the evening) and cheapest during off-peak periods (for example, overnight).

How TOU is calculated

Time-of-use tariffs are made up of four charges. The following applies to an ACT residential time of use tariff. Refer to our schedule of charges for other time of use tariffs.

  • Supply charge - A fixed price per day charge for the supply of electricity to your premises.
  • Energy consumption at 'peak times' - c/kwh rate applied to usage from 7.00am to 9.00am and from 5.00pm to 8.00pm every day.
  • Energy consumption at 'shoulder' times - c/kwh rate applied to usage from 9.00am to 5.00pm and from 8.00pm to 10.00pm every day.
  • Energy consumption at 'off-peak' times - c/kwh rate applied to consumption for all other times.

Tips for using a time-of-use tariff

  • Use electrical appliances during off-peak or shoulder periods.
  • If you have alternative energy sources, like gas for cooking, use these instead of electrical appliances.
  • Use appliances only when necessary and switch them off when they're not being used in peak times.
  • Set your air conditioner to an energy-efficient 25 degrees but try to avoid running it during the peak times.
  • Talk to a licensed electrician about switching your pool pump, hot water system and dishwasher to an economy tariff or put on a timer to operate outside of peak times.
