How residential tariffs work
A tariff is how we calculate your electricity bill. Let's break down the components that make up our residential tariffs:
- Usage charges This is your total usage for the billing period. You pay for each kWh used. This can be charged at a flat rate or based on ‘time of use’ pricing, meaning the cost will vary depending on the days and times when power was used.
- Service fee A daily fee that helps cover the cost of supplying your service. This includes building and maintaining transmission and powerlines, billing and administration.
- Demand charges Demand charges only apply to demand tariffs. Your electricity demand is based on your highest electricity use in a 30-minute window during the evening peak period. The demand charge is based on the single highest spike during your billing cycle - not your total usage. Managing when you use appliances can help reduce demand spikes, and potentially lower costs. Demand tariffs can help you save if you can minimise your use during peak periods.

Hi, I’m Skye from Ergon Energy Retail here in Rockhampton. And today we’re going to be making your electricity tariffs easy to understand. Let’s break down your tariff options so you can understand what might work best for your household.
First up, let’s talk about primary tariffs. Every home has one. A primary tariff supplies electricity to the majority of the appliances in your home, whether that’s a fridge, your fans, your power points and lights. They power all of the essentials.
You have three choices for your primary tariffs. These are flat rate, time of use and demand.
First of all, we’ve got flat rate tariffs. This one’s super simple. You pay the same flat rate per kilowatt hour all day, no matter what time of the day it is. Plus a daily service fee. Go Queensland! Woooo!
Another option is time of use tariffs. These rates change depending on when you use your power. Daytime, between 11am to 4pm is the cheapest. The peak is between 4pm to 9pm and that’s the most expensive. All other times are mid-range prices. There’s also a daily service fee.
If you’re home during the day and can shift things like doing the laundry, dishwashing, air-conditioning or other larger appliances to daytime, a time of use tariff could be for you.
And then we have demand tariffs. With these tariffs, the rates you’re charged change throughout the day depending on when you use your power.
There is a demand charge based on your highest half hour of use during 4pm to 9pm each month. So a demand tariff is great if you use power during the day or overnight, and can avoid using a lot of power at once during the 4pm to 9pm peak. There is also a daily service fee.
So those are all the primary tariffs options. Now let’s talk about secondary tariffs, also known as economy tariffs. These are perfect for appliances that don’t need a constant electricity supply. Like hot water systems, pool pumps or even EV chargers.
Because supply can be interrupted, usage rates are cheaper on an economy tariff. To switch to an economy tariff, you’ll need the help of a licensed electrician.
Not sure which tariff is right for you? That’s ok, we’re here to make it easy. Our free tariff comparison tool takes the guesswork out of it, and helps you find the best fit for your household in just a few clicks. You can see savings on your energy bills, without changing how or when you use your power.

Demand charging explained
What’s demand charging?
In short: Demand charging is about how much electricity is used at the same time.
Think of it like filling a bucket with water:
- Turn the tap 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.
The more power that’s used at once, the higher the demand.

How is demand calculated?
We look at the 30-minute window between 4pm and 9pm on any day in the month when you used the most electricity. That’s your peak moment.
Here’s how we work it out:
- Convert the peak to kilowatts: 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.
- Apply the demand rate: Then we multiply that by the daily rate ($/kW/day) and the number of days in your billing period.
- How the daily rate is set: The demand charge is displayed on a monthly basis, but billed based on the number of days in the billing period. To get the daily rate, the monthly calculation needs to be multiplied by 12 and then divided by 365.25.
This helps cover the cost of keeping the network ready when demand is at its highest - so everyone stays powered up when it matters most.

- There’s a one‑off cost of $199.24 inc. GST for standard residential properties, which will be charged via your electricity bill.
Frequently asked questions
How can I run my appliances on an economy tariff?
To connect an appliance to an economy tariff, contact a licensed electrical contractor to discuss your needs and arrange for any work to be completed.
Your electrical contractor will let us know when the changes have been made.
Can I connect an air conditioner to an economy tariff?
Yes, but power may be temporarily switched off during peak demand times (like hot summer evenings) to help manage the network.
Before connecting your air conditioner:
- Consider keeping some AC units on a standard tariff
- Use ceiling or pedestal fans as a backup
- Cool the room earlier in the day, before peak demand (typically 4–9pm).
If you rely on air conditioning for health or comfort, a standard tariff may offer greater peace of mind.
When I'm on an economy tariff, when will power be available?
Ergon Energy Network manages the hours of supply for these tariffs, which may be switched off at any time to manage electricity demand. Each day, Tariff 33 is available for at least 16 hours and Tariff 31 is available for at least 8 hours. Supply times vary and can change daily.
