Peak and off-peak electricity times

Peak and off-peak electricity times explained

Fact Checked Fact Checked


KEY POINTS

  • A single rate tariff refers to a fixed price for electricity unaffected by the time of day it is used. A time of use tariff refers to different prices for electricity depending on when it is consumed (e.g. off-peak vs peak times).
  • Peak and off-peak period electricity rates are only applicable on a time of use tariff.
  • Single rate tariffs are cost-efficient for customers who consume more energy during peak periods, while time of use tariffs can help customers who consume less energy during peak periods save on their energy bills.

In this Canstar Blue article, we discuss the various peak and off-peak electricity hours available to Australian households, showing how they  work with examples from the ‘Big 3’ energy providers – AGL, EnergyAustralia and Origin.

Peak and off-peak electricity times

Peak, off-peak and shoulder electricity usage times vary between energy retailers and states.

But as a general guide, we have listed times for AGL, Origin and EnergyAustralia below.

Please note that these time periods may change in the future which is why it’s always best to refer to the energy price fact sheets.

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 such as hot water heating or your pool pump is metered at a reduced rate
  • A time of use tariff charges  different prices for electricity depending on what time of day it is used. In this scenario, ‘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 (with the exception of 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 below example 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 be thinking 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 (i.e. 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 prices

Typically, peak electricity prices cost upwards of 40c per kilowatt hour (kWh), with some retailers charging as much as 60c/kWh in some cases.

Off-peak electricity prices generally tend to sit around the 15c-25c/kWh mark depending on location, although some retailers have been known to charge under 10c/kWh before for either shoulder or off-peak times.

There is a dramatic difference in peak and off-peak prices. If you are signed up for a time of use tariff, shifting a good percentage of your daily energy usage to off-peak times would be a smart way to reduce your energy bills.  If you face trouble delaying the bulk of your energy usage to off-peak hours – you could be better off sticking with ta single rate tariff, whereby you’ll pay the same price for power at all times and reduce your chances of bill shock.

For a time of use tariff to work out cheaper than a single rate tariff, you will likely need to shift about a third of your daily energy requirements to off-peak hours (generally 10pm to 7am).

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. In order 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 later 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.
