Billy, run by the Electricity Authority, is a free power comparison tool that helps you find the best power plan for your home and easily switch providers.
Compare power plans
If your power bill looks a little high, you've changed how much electricity you use, or you’d like to see what options are out there, Billy can help. This tool makes comparing plans and switching providers as simple as a few clicks.
Consider an off-peak power plan
Power companies offer plans that reward you for using energy during off-peak times, like nights and weekends, when demand across the country is lower.
These plans, often called off-peak, time-of-use, flexi or ecosaver, can save you money while helping the grid stay sustainable. They are especially great for households that use more energy during off-peak hours, like charging EVs overnight or heating rooms while kids sleep.
These plans typically offer cheaper or discounted power at specific times, and could save you up to $150 a year — just be sure to check the details.
Shift your energy use
If you switch to an off-peak power plan or are already on one, make sure you shift your energy use to those discounted times. Power companies might charge higher peak rates to offset the discounted offers. This means if you don’t shift your use to those discounted windows, you could potentially end up spending more.
Adapt when your usage changes
Your household energy use changes over time, and your power plan should change along with it. This helps ensure you're paying the lowest price for the energy you're using. These major improvements can have a big impact on your home's overall energy use.
