How we make money →How we calculate these estimates
Figures are each retailer's cheapest qualifying single-rate market plan from Consumer Data Right plan data, costed at the AER/ESC benchmark usage for the zone and compared against the reference price. Actual plan rates vary by postcode.
Estimated costs can vary by usage, tariff type, retailer, distributor, and address. Both supply charges (the daily fixed cost of being connected) and usage rates (c/kWh) affect your total bill. Solar feed-in tariffs vary by retailer and plan. Always review plan details, fees, and conditions before switching.
Data sources
- Consumer Data Right plan data
- AER Default Market Offer (DMO) reference price
- ESC Victorian Default Offer (VDO) reference price
These are indicative estimates only. Your actual bill depends on your specific plan, usage patterns, and applicable discounts. Read our full methodology.

How we make money
EnergyPlans is free to use. Here is where the money comes from.
Where the prices come from. Plan prices and the EnergyPlans Default Price Index come from the government's whole-of-market Consumer Data Right feed, the data retailers have to publish. We refresh it every day. No retailer pays us to be listed, to rank higher, or to be shown as a good deal. Rankings follow the method on our methodology page. A plan in that feed can still be left out of a cheapest figure where that method says so.
How we earn. When you decide to switch, we hand you to Compare & Connect, operated by Residential Connections Pty Ltd and owned by Origin Energy Limited. If you sign up to a plan through them, they pay us a small commission. That is what keeps the data and guides free. You do not pay us. Origin's ownership of our partner does not change the prices we publish or the order we rank plans.
Worth knowing. Compare & Connect can only sign you up to the retailers they have agreements with. That may not be every retailer you see on our site. If the plan you want is with a retailer they don't cover, you can go to that retailer directly, or use the government's free comparison site, Energy Made Easy (energymadeeasy.gov.au). In Victoria, the government's free comparison site is Victorian Energy Compare.
The commission is not added to your bill, and it never changes the prices we show or the order we rank plans. You choose the plan.
