Origin Energy and EnergyAustralia at a glance
Origin and EnergyAustralia both sell in every state of the national market, including the ACT. Origin is ASX-listed. EnergyAustralia is owned by Hong Kong's CLP Group.
EnergyAustralia leans on guaranteed discounts, quoting a percentage off its usage and supply charges. Origin generally publishes its rates without them. Guaranteed discounts are applied in our figures, and conditional ones, which depend on paying on time or by direct debit, are not.
If you live in regional Queensland, only Origin publishes plans in the Ergon network, so this comparison does not apply there.

Which one should you choose?
On price alone, EnergyAustralia comes out ahead in more of the networks they share. The gap in any one network is what matters for you, and it can change when either retailer updates its plans. If solar exports matter, compare feed-in rates on the specific plans. If you can shift usage to the middle of the day, look at time-of-use and Solar Sharer plans as well as flat rates.

How these prices were worked out
Every price on this page comes from the plans retailers publish to the AER's Energy Made Easy data under the Consumer Data Right, as at 14 October 2026. We price flat-rate (single rate) plans that any household in the area can sign up for, at 2,500, 4,000, 6,500 kWh a year, including GST, the daily supply charge and guaranteed discounts. Conditional discounts, such as for paying on time, are left out. Plans limited to members, existing customers or homes with particular equipment are excluded. Retailers with wholesale-linked prices are listed separately, not ranked.
Prices change, sometimes weekly. Always confirm the current price on the retailer's plan fact sheet or a government comparison site before you switch. Our switching guide covers the steps.
