You will see a reference to different types of tariffs on your electricity bill. A tariff is the cost for each unit of energy you use measured in kilowatts (kw). Most households are on a single (or flat) rate or time-of-use tariff for their variable charges.
The peak pricing periods are generally between 3pm and 9pm daily. Lower off-peak pricing has traditionally applied to overnight use, but from July 2021 a new time-of-use tariff offers lower prices during the day as well. By using power in these new off-peak times, you’ll help to make the most of the growing supply of renewable energy available across the network.
When discussing your energy plan with your retailer, you have a choice about which type of tariff or pricing structure will suit your home and lifestyle. These include:
- Single rate tariffs: A good option for families that need an everyday low rate.
- Time-of-use tariff: These offer cheaper rates if you can use electricity at specific times – like running your washing machine or dishwasher in off-peak periods – or if you have a rooftop solar system or electric vehicle charger. Different time-of-use options are available, depending on the appliances you use and when you use them.
- Controlled load tariffs: These are designed for appliances that run overnight or in off-peak times, like water heaters or electric vehicle chargers.
- Demand tariffs: These are charged based on your maximum power usage during a specific period intime, rather than your total usage over time.
When considering tariffs, remember to look at your energy retailer’s Basic Plan Information Document for all the terms and conditions.
