Glossary: 

  • Time of use tariff: When customers are charged different prices for their electricity usage based on the time of day. To be eligible for this tariff, you must have a smart meter installed.
  • Peak hours: When the usage cost of electricity is most expensive on a time of use tariff.
  • Off-peak hours: When the usage cost of electricity is at its cheapest on a time of use tariff. 
  • Shoulder hours: When the usage cost of electricity sits somewhere in the middle between peak hour and off-peak hour pricing. 

For added specificity, we have listed times for AGL, Origin and EnergyAustralia below.

Please note that these periods may change in the future

If you’re with a different retailer, you can check their peak and off-peak usage times and charges by reviewing their energy price fact sheets.

What does ‘peak usage’ mean?

You will see the term ‘peak usage’ on electricity bills, but this can mean different things to different customers, depending on the type of energy tariff they are on.

  • A single rate tariff charges the same unit price for electricity regardless of the time of day it is used. However, energy retailers still refer to these prices as ‘peak usage’. This is especially true if you are on a controlled load tariff, where an energy-intensive appliance is metered at a reduced rate.
  • On a time of use tariff, ‘peak usage’ reflects the amount of energy used during electricity peak hours.

Peak usage information alongside all other cost details – including other tariffs – can be found by reading your electricity bill.

In the case of a household on a single rate tariff, the peak usage component will simply reflect all energy usage (except a controlled load, if applicable).

Customers on a time of use tariff can locate their peak usage costs next to their off-peak costs, ‘shoulder’ costs (the time between peak and off-peak hours, if applicable) and daily supply charges.

The example below is an Origin bill for a household with a time of use tariff.

How to check when electricity rates are peak and off-peak

If you’re not sure which tariff you’re on, check your electricity bill or contact your energy retailer.

Currently, the vast majority of Australian households are on a single rate tariff, but you should be aware of the type of plan you’re on before adjusting your electricity habits.

Customers on a single rate tariff could incorrectly think they are paying different rates for power throughout the day and therefore delaying their consumption to no benefit.

Peak and off-peak electricity rates are only applicable for Aussies signed up to a ‘time of use’ or ‘flexible pricing’ tariff. To do this, a smart meter must be installed on their property.

Electricity users will only be on a time of use tariff if they have discussed the option with their energy retailer and believe it is financially beneficial (e.g. generally using more electricity during the day or late at night, rather than the early evening).

Because there’s no guarantee that a time of use tariff is better than a single rate tariff in your situation, it’s important to consider your usage habits before switching tariff types.


Peak vs off-peak electricity times in NSW, QLD, VIC and SA

Customers in New South Wales, South East Queensland, Victoria and South Australia will generally have different peak, off-peak and shoulder times, even from the same energy provider.

If you are interested in learning more, you can find more information on your energy provider’s website.


Should I use peak and off-peak electricity rates?

Peak and off-peak electricity rates can be beneficial for some households, but it isn’t a one-size-fits-all scenario.

It is likely not the best move for Aussies who disproportionately use lots of power in the early evening. To save money, it’s best to reduce energy usage as much as possible during peak hours.

Single rate tariff users won’t need to worry about what time of day to use power, as the tariff will remain unchanged.

For customers who use a large portion of power during the day or in the late evening, and/or have a solar battery with rooftop solar panels, having cheaper rates during off-peak and shoulder periods may be cost-effective.

Keep in mind that to be charged different rates at peak and off-peak times, the property must have a smart meter installed and be signed up for a time of use or flexible pricing tariff.

Whatever the type of tariff, it’s always a smart move to regularly compare providers, plans and prices to avoid paying too much.
