The Australian energy market might seem complicated, but Selectra is here to help. How do you choose the best energy provider in Australia? What tariff is right for you? And what exactly is the NEM? Let’s keep reading below to find out more about the energy market as well as different providers for electricity and gas in Australia.

Energy Providers in Australia

With over 114 electricity companies and energy providers in Australia, there are plenty of options to choose from.

Choosing the best energy provider really depends on what you’re looking for. Are you looking for smaller, greener power suppliers or are you looking for big-name power suppliers? Regardless of the one you choose, in Australia, you are sure to have options available.

Types of Energy Providers

The Big Three Energy Providers

"The Big Three" is the nickname for the three biggest power suppliers in Australia.

The Big Three are:

The Big Three energy providers are the largest and most historic energy suppliers in the country. The Big Three control around 65% of the energy market share combined.

However, The Big Three also receive the most complaints and tend to have low customer ratings.

What Are Tier 1 Energy Providers?

Along with The Big Three, a few more energy providers make the cut as Tier 1 power suppliers.

A Tier 1 energy company is any power supplier that holds 10% or more of the market share in any energy network region.

Tier 1 energy providers are:

*Lumo Energy and Red Energy are both owned and operated by Snowy Hydro.

All of these tier 1 power suppliers are well known and hold their own as newer energy companies begin to crowd the market.

What Are Tier 2 Energy Providers?

Tier 2 energy providers include any power supplier that holds less than 10% of the energy market share within a network region.

Oftentimes, Tier 2 energy providers offer more niche energy services such as:

wholesale energy subscriptions
100% carbon neutral energy
green energy
community project initiatives

As more and more Power suppliers join the National Electricity Market, Tier 2 providers are becoming an attractive alternative to the big-name energy companies.

Australian Owned Energy Companies

Despite having over 114 electricity companies in Australia, few are actually Australian owned.

There are 21 Australian owned energy companies operating within the country.

Below you'll find a list of all the Australian owned energy companies:

Providers That Bundle Electricity & Gas

Bundling electricity and gas with one provider is often the easier choice. You don’t need to deal with more than one energy provider, and your energy provider gets two services from you. While not every electricity provider also offers natural gas, here are some of the best energy providers offering not only gas plans, but electricity as well. It’s important to remember that not every energy provider offers both gas and electricity plans to every location.

Renewable Energy Companies Australia

Below we have ordered Australia's renewable energy companies from Greenest to least green.

Here is a list of the greenest renewable energy companies in Australia:

See our full story on the greenest energy providers.

Energy Providers that Offer Green Power

Green Power is a government-accredited initiative that enables energy consumers to offset their energy usage. Customers can choose to offset between 10% and 100% of their energy consumption, often at a small additional cost. Some providers that offer Green Power include:

Australian Energy Providers Offering Green Power
A-L	M-Z
ActewAGL AGL Aurora Energy Diamond Energy Dodo Energy Locals EnergyAustralia Enova Energy Ergon Energy Lumo Energy	Momentum Energy Origin Energy OVO Energy Nectr Powershop ReAmped Energy Red Energy Simply Energy Tango Energy

It’s important to understand that Green Power does not mean you yourself are getting your energy from a renewable or green energy source. Rather, after you consume your energy your provider pays into the program on your behalf to support future renewable initiatives.

Carbon Neutral Energy Providers

Similar to Green Power, energy providers can also choose to carbon offset the energy customers consume by supporting renewable energy development globally. Unlike Green Power, carbon offsetting is often free, without an additional charge to the consumer, but it also means fewer energy providers offer this carbon offsetting. Energy companies that offer carbon-neutral initiatives include:

AGL
DC Power Co
EnergyAustralia
Energy Locals
Enova Energy
Nectr
Origin Energy
OVO Energy
Powershop
Simply Energy

How to Switch Energy Providers in Australia

Since the deregulation of the National Electricity Market, switching energy providers is easier than ever.

In fact, customers can compare electricity and gas plans online, and switch directly through their chosen provider's website, by calling them, or using a comparison service like Selectra to make the switch for you.

You will most need to provide a valid form of ID and consent to a credit check in order to get the best energy rates available. Once you sign up with your new energy provider, they will take charge of contacting your old provider and letting them know you’ve switched.

Your old provider will take a final meter reading, and send you a final energy bill. After that, you will have been switched to your chosen new energy provider.

When you switch energy providers, you don’t need to worry about losing access to electricity and gas in your house during the switch. As your distributor is the one actually providing energy to your house, your energy service will not be cut out while you transfer to a new provider.

You also don’t need to worry about paying to switch providers. Unless you are fully disconnecting/reconnecting due to moving house or developing a new property, in which case there will probably be an additional fee involved, there is no cost to switching energy providers.
