Demand tariffs
On our residential demand tariff, you pay time of use rates each day, a demand charge for the maximum demand in the evening peak period, and a daily supply charge.
Your electricity demand is based on your highest electricity use in a 30-minute window during the evening peak period. Demand tariffs can help you save if you can minimise your use during peak periods.
Please be aware the tariff links below will take you to the Australian Governments' Energy Made Easy website. Once the page loads, you will need to enter your postcode to see the tariff information (it may take a few seconds for this to appear).
Tariff 14C
This demand tariff is for customers that can minimise peak demand between 4pm and 9pm every day of the year.
The demand charge is displayed on a monthly basis but billed based on the number of days in the billing period. To convert from a monthly to daily basis, the monthly calculation needs to be multiplied by 12 and then divided by 365.25.
While the daily supply charge is lower than Tariff 11, customers should take the demand charge into account in determining whether this tariff is suitable. All rates include GST.
Peak period: 4pm to 9pm daily
Night (shoulder) period: 9pm to 11am daily
Day (off peak) period: 11am to 4pm daily
| From 1 July 2025 - Current Rate | COST |
|---|---|
| Peak demand per kW per month | $8.53490 |
| Peak usage per kWh | $0.24984 |
| Day (off peak) usage per kWh | $0.22680 |
| Night (shoulder) usage per kWh | $0.28035 |
| Supply charge per day | $1.26666 |
Here’s the details with peak demand charges:
We look at the 30-minute window between 4:00 pm and 9:00 pm on any day in the month when you used the most electricity. That’s your peak.
How we work it out:
- We take your highest 30-minute usage in kilowatt-hours, then double it to get kilowatts (kW). Why double? Because we’re converting half an hour into an hourly measure.
- Then we multiply that by the daily rate ($/kW/day) and the number of days in your billing period (think 30 for monthly, 90 for quarterly).
It’s all about reflecting the cost of using the network when everyone’s cranking the power at the same time.

What is demand charging?
It’s not just about how much electricity you use, it’s about how fast you use it.
Think of it like filling a bucket with water:
- Turn the tap on halfway and fill it slowly - that’s low demand.
- Crank the tap full blast and fill it fast - that’s high demand.
Electricity works the same way. A few small appliances? Low demand. But fire up the air con, oven, and a few big machines all at once? Your demand shoots up.
So, the faster you draw power, the higher your demand. Simple as that.
Why does it matter?
We’ve got to be ready to deliver power the second you flick the switch. If everyone wants electricity at the same time, we need extra capacity to keep the lights on and the air cons humming.
That spare capacity isn’t free, so demand charges help cover the cost of having that backup ready when you need it most.
How is it charged?
Demand is charged based on your highest peak period usage during one 30 minute period (measured in 30 min intervals) during the billing period.
For homes and small businesses, we measure this in kilowatts (kW), and you’ll see it as a separate line on your bill.
Changing your primary tariff
There's no cost to change your primary tariff. We'll never change your tariff unless you explicitly consent:
- If you’ve had a smart meter for at least 12 months: You can request a tariff change in My Account. Simply select 'Usage & metering’ from the menu, click the 'Compare tariffs' button and follow the prompts.
- If you’ve had a smart meter less than 12 months: Please call our friendly local team on 13 10 46 to request a tariff change.
- If you have a basic meter: You’ll first need to upgrade to a smart meter. You can request a smart meter using our easy online form. While there’s no additional charge for a smart meter, your switchboard needs to be compliant for the meter change to take place. Your electrical contractor can assist you in assessing your switchboard.
