AGL, Origin or EnergyAustralia: Which provider is best?

As far as power companies go, it doesn’t get any bigger than AGL, EnergyAustralia and Origin.

Known as the ‘big three’ energy providers in Australia, these giants still hold most of the market share and are often turned to as a reliable choice for consumers. But, does size really matter when it comes to household energy, and if it does, which retailer offers the cheapest electricity prices and best customer rewards? Let’s find out.

Cheapest Big 3 Provider in Australia

It goes without saying that price is arguably the most important factor when comparing energy providers. Recent Canstar Blue research found that almost a third of Australians (32%) were attracted to lower rates, while one in four shopped (26%) around and compared plans on price. With this in mind, take a look below to see which of the big three is cheapest in your state.

  • New South Wales: EnergyAustralia is currently the cheapest in Sydney on the Ausgrid network
  • Victoria: EnergyAustralia is currently cheapest in Melbourne on the Citipower network
  • Queensland: Origin and AGL are currently tied for cheapest in Brisbane on the Energex network
  • South Australia: EnergyAustralia, Origin and AGL are currently tied for cheapest in Adelaide on the SA Power network

Keep in mind electricity prices change all the time and will vary across different energy distribution networks.

This could mean that many bill-payers find comfort in companies they’ve heard of before. While there’s no issue with playing it safe (so to speak), electricity all comes from the same poles and wires regardless of how well-known a provider may be.

Which is best for solar customers?

All three offer compelling deals and feed-in tariffs for customers with solar panels. AGL’s solar range includes the ‘Solar Savers’ plan in New South Wales, Victoria, South East Queensland and South Australia that offers a higher feed-in tariff (FiT) rate than its standard electricity plans. EnergyAustralia also offers a feed-in tariff to customers with solar panels in New South Wales, Victoria, South East Queensland and South Australia, as well as a solar and battery system with no upfront costs in New South Wales. Last but not least is Origin’s solar packages, where customers can sign up to its deals, one of which has a boosted FiT if a solar system is installed by the retailer.
