Ever noticed your electricity bill just keeps shifting, even when your usage remains the same? Wondering why your bill fluctuates even when your usage doesn’t? That’s probably because of something known as a time-of-use tariff. Rather than charging a single flat rate, this pricing model varies depending on when you use electricity.
In this blog, we will walk you through how TOU tariffs work, why timing plays an important role in modern households, and how Australian businesses or households can save hugely by aligning their usage with the clock.
Let’s now quickly unlock this dynamic pricing model – explained in clear and simple terms.
Quick Summary:
In this blog, you will learn exactly how a time-of-use tariff actually works, what distinguishes it from flat-rate energy plans, or how it can affect your bill based on when you use electricity. We will also explore peak vs off-peak electricity, explain TOU pricing Australia, and share practical tips to thoroughly optimize your usage.
How Does a Time-of-Use Tariff Work
Intrigued about what a TOU is and exactly how it works? Deep dive into this quick guide to ace the deal –
Definition and Basics
A time-of-use tariff refers to the price you pay for electricity differing based on the day of the week, the time of day, and of course, the season.
- At the peak hours, electricity tends to be most expensive.
- During off-peak hours, electricity is significantly more affordable.
- Shoulder periods fall between these two and have moderate rates.
This is different from flat-rate plans, where the pricing remains constant irrespective of when you use power.
Why is TOU Used?
The Australian grid operates just like a supply-and-demand marketplace. When more people consume power – especially in the evening – both demand and costs go up. The TOU pricing Australia encourages users to shift their usages to low-demand hours.

Time-of-Use Tariff Schedules – Peak vs Off-Peak Electricity Debunked
Common TOU Schedule in Australia
| Period | Time Range | Rate Type |
| Peak | 4 PM – 9 PM | Highest (e.g., $0.40/kWh) |
| Shoulder | 7 AM – 4 PM/ 9 PM – 10 PM | Medium (e.g., $0.25/kWh) |
| Off-Peak | 10 PM – 7 AM | Lowest (e.g., $0.15/kWh) |
Important Note – Rates and timings might differ by state and electricity distributor.
A Quick Example – TOU Pricing in Action
Imagine you run your laundry or dishwasher at 10.30 PM instead of 6.30 PM. This seemingly simple shift can slash your energy bill by 35-40%, courtesy of the lower off-peak electricity rates.

Are You on a Time-of-Use Tariff? How Will You Know?
Step-by-Step: Start Checking Your Current Plan
- Check your current bill – do you notice multiple rates listed for various time slots?
- Log into the portal of your energy retailer and check their plan type.
- Connect to your provider in case you’re still unsure.
Are You in Need of a Smart Meter?
Yes – most of the time-of-use tariff plans need a smart meter. These meters help in recording the hourly usage and sending data remotely. Visit our Energy Comparison Tool to explore more about the installation of smart meters and how they work.
Advantages and Drawbacks of Time-of-Use Tariffs
Why Most Aussies Are Switching?
The Core Advantages –
- Pay less at the off-peak electricity times.
- Encourages efficient usage of energy.
- Smart meters in Australia provides real-time energy usage data and insights.
Disadvantages You Can’t Overlook –
- Costs go up if your usage is mainly at the peak hours.
- Not suitable for households with fixed usage schedules.
Pro Tip: In case you work from your home or can automate your appliance, TOU pricing Australia could be your key to lowering energy costs and saving money.
EXPERT TAKE – Why Time is Important in Energy Pricing
Time-of-use pricing helps in stabilizing demand on the national grid while offering households cost-saving opportunities by changing their electricity usages. It’s a win-win situation for both the energy infrastructure as well as consumers. — AER (Australian Energy Regulator) Brief.
Who Makes the Most from Time-of-Use Tariffs?
Perfect for Flexible Users
You will gain most of the perks from a time-of-use tariff in case –
- You are home at the daytime (e.g., remote workers or retirees).
- You run major appliances at the off-peak electricity times.
- Your household is equipped with automation tools like timers, smart plugs, solar batteries, etc.
When Flat Rates May Be Better
If you have a 9-to-5 job or you consume most of your electricity, especially at night, time-of-use could cost you a lot more. A flat-rate plan might be simpler and more predictable.
How to Enhance Time-of-Use Savings
Practical Tips to Lower Costs
- Run the washing machine and dishwasher and during the off-peak electricity hours
- Make sure that you use smart devices or timers to automate usage
- Ensure that you charge your electric vehicles overnight
- Pre-heat or pre-cool your home at the shoulder hours
- Consider using energy-efficient appliances that offer delay-start features
What Tools Can Help?
- Energy tracking apps
- Smart meters as well as in-home displays
- Real-time insights from your retailer
Always keep in mind – It’s not about using less, but it’s mainly about using smart.
Some of the Most Common Questions on Time-of-Use Tariff
- Can I Switch Back to any Flat-Rate Plan?

So, Should You Really Consider Time-of-Use Tariffs?
If you need more control over your electricity bill and can adjust your overall usage times, a time-of-use tariff is worth taking into consideration. You will save the most if you shift your usage to the periods of off-peak electricity and gain an understanding of TOU pricing Australia structures.
The good news? You’re never stuck. You can always thoroughly test it for a billing cycle and go back if required. Begin by checking your meter, thoroughly reviewing your plan, and understanding how flexible your routine is. In case you have control over your schedule, you could see a lot of savings.
