How we rate SA electricity providers


Given the cost of power in South Australia, you’ll naturally want to find a cheap deal – and we can help you with that. However, we can also show you which SA electricity companies are rated highest based on the experiences of their customers. Paying a low price is good, but not if it comes at the expense of other factors, such as customer service. That’s why our ratings are designed to give you as much information as possible before you pick your next retailer. Keep in mind though that, while our ratings include six of the most prominent electricity retailers in SA, you may find others operating in your area.


Canstar Blue surveyed 806 South Australian households for their feedback on their electricity retailer. Respondents had to live in South Australia, have an electricity account and pay the bills for their response to be eligible.

  • The outcomes reported in these ratings are measured via ISO 26362 accredited research panels managed by Qualtrics.

Respondents rate their satisfaction with their electricity supplier from zero to 10, where zero is extremely dissatisfied and 10 is extremely satisfied. Provider satisfaction was rated by respondents on the following criteria:

  • Overall satisfaction: measured consumer satisfaction with an electricity provider as an individual score NOT a combined total of all criteria.
  • Value for money: cost was low for the quality and effectiveness of the electricity provider.
  • Customer service: the electricity provider had multiple service points for customers, e.g. telephone, email, online chat.
  • Bill and cost clarity: the electricity provider had an easy-to-understand bill.
  • Online tools and advice: the electricity provider had an app or online account to monitor energy usage, pay bills and manage account information.
  • Ease of sign-up: the electricity provider had a simple sign-up process.

The winning brand is the one that receives the highest Overall satisfaction rating once all the scores from the Overall satisfaction criteria are combined and averaged.

  • Overall satisfaction is asked as a specific question and represents an individual measure, not a combined total of all criteria.
  • When we cannot determine a clear winner from the criteria for the Overall satisfaction rating, we will then look at the other criteria measured in the rating.
    • The brand with the highest number of five-star ratings within the supporting criteria will become the five-star recipient in overall satisfaction, and thus win the award. If a clear leader still cannot be determined from the supporting criteria, joint winners will be declared.

Brands must have received at least 30 responses to be included, so not all brands available in the market have been compared in this survey. The brands rated in this survey are listed below in order of best overall satisfaction.

Lumo Energy has re-emerged as the top electricity provider in SA this year, scoring an almost clean sweep of five-star ratings across the board. The exception to this was its online tools and advice, where it received four stars.

Engie scored four stars for overall satisfaction this year. It also received four stars for its customer service, bill and cost clarity and ease of sign-up. For its value for money and online tools and advice however, it received a noble five stars.

3. Alinta Energy


Ratings result

In this year’s review, Alinta Energy ended up with a mixed bag of results. For overall satisfaction, value for money, bill and cost clarity and ease of sign-up, this retailer earned four stars. For its customer service it was bumped up to a five-star rating, while its online tools and advice received just three stars.

Editor’s notes

Alinta Energy is a major electricity and natural gas supplier across most southern states in Australia. The retailer keeps things relatively simple with just one or two market offers in each of the states it serves. Alinta Energy is owned by Hong Kong-based conglomerate Chow Tai Fook Enterprises but is headquartered in Sydney, with another major office located in Perth. The retailer is also a big contender in the natural gas market in Western Australia.

Editor’s notes

Energy giant Origin has moved away from large conditional discounts, instead offering relatively low-rate plans and other sign-up perks. Origin offers variable rate products and all plans come with no exit fees or lock-in contracts. One plan even has Everyday Rewards points up for grabs. As one of Australia’s leading solar power retailers, Origin also has specific plans for customers who own solar panels.

Editor’s notes

As you might expect from one of the big retailers, EnergyAustralia has a major presence in South Australia. It offers customers a few different variable rate plan options, all of which are available over a 12-month benefit period. Aside from this, the retailer has also since introduced a new plan designed for customers who have solar panels on their roof.

How to find the best electricity deal in SA

If you haven’t worked it out yet, finding the best provider and plan for your requirements can be extremely tricky. The fact is that there is no one-size-fits-all solution to energy costs in South Australia. Instead, you will need to work out which offer best meets your needs based on primarily:

You should also keep in mind that the ‘cheapest’ electricity provider doesn’t necessarily mean the ‘best’. Our ratings are based on customer satisfaction, rather than just the cheapest rates. Our cost comparison report for SA electricity providers, however, is a useful guide to which retailers offer the cheapest deals. Ultimately, you will want an electricity provider that has competitive rates, but also delivers reliable bills and good customer service when you need it.

Who is the cheapest electricity provider in SA?

It’s worth noting that energy prices change all the time in South Australia, so it’s hard to pinpoint the cheapest retailer at any one time. That said, GloBird Energy and Amber are typically some of the cheapest electricity providers in SA. With more than 15 power companies to choose from, finding the lowest prices and best value deals in your area will require some research.

Aside from price, it’s still important to check out other credentials of energy companies, like customer service, sign-up incentives and rewards programs. Although price may have the biggest impact on making a decision, it’s good to know which brands are willing to work a little extra for your business.

How long does it take to switch electricity providers in SA?

Changing energy providers usually takes about two business days, after this time your account should be taken over by your new company. This means that your old provider will have about 48 hours to send you a final bill estimate and pass your details on to your new provider.

Switching to a new electricity provider is usually straightforward and can be done online or over the phone in minutes. After you’ve switched, you’ll likely receive a final bill from your old retailer and be updated once your account has been taken over by your new provider.

FAQs about SA electricity providers

The list below features all the electricity providers that currently list plans in South Australia as per our database.

  • 1st Energy
  • AGL
  • Alinta Energy
  • Amber
  • Diamond Energy
  • Dodo
  • EnergyAustralia
  • Engie
  • GloBird Energy
  • Kogan Energy
  • Lumo Energy
  • Momentum Energy
  • Origin Energy
  • OVO Energy
  • Pacific Blue
  • Powershop
  • Red Energy
  • Sumo

These retailers all operate on the SA Power network, meaning prices are consistent across the network and the state. Please note, there may be other providers in your area.

While some energy retailers play it straight with their electricity plans, it’s common to see various promotional offers or plans targeting a specific consumer segment to get new customers to sign up. Lumo Energy, for example, has a rewards program whereby customers can get money off at various retail outlets and theme parks. While tempting, it’s important to compare electricity providers in SA on their supply and usage charges before taking any discounts and incentives into account.

Most electricity plans in South Australia come with a feed-in tariff for solar customers. However, feed-in tariffs in South Australia can vary between providers. There are also few solar-specific plans available in SA. Nevertheless, retailers are competing to offer the most attractive feed-in tariffs, with rates of up to 20 cents per kilowatt hour (c/kWh) currently available to new and eligible customers.

Given the high prices that South Australians often pay for electricity, you would be forgiven for thinking there wasn’t much competition between providers in the market. The price of any product or service generally gets higher when there is no competition. However, this is not the case in South Australia as there are many different electricity providers fighting hard for new customers. The problem is the cost of electricity generation, transmission and distribution, which these energy companies need to pass onto their customers. However, the extent to which these costs are passed on to households is the subject of much debate. South Australia is also heavily reliant on renewable energy generation.

South Australia is home to more than 20 solar operating and wind farms, with a mix of private and public ownership. And while there are no more coal-fired power stations in the state, much of the electricity generated still comes from gas turbine power stations. AGL, Origin and EnergyAustralia all own gas turbine power assets in South Australia, however, AGL has since begun the process of closing its gas turbine assets down, with a full closure expected by 2026.

After years of increased competition in South Australia, recent figures from the Australian Energy Regulator (AER) show that many smaller retailers are chipping away at the market share of the bigger players, like AGL, EnergyAustralia and Origin. Despite this, AGL still has the largest customer share in SA, with Origin, Engie and EnergyAustralia also accounting for large chunks of the market. It shows that since the market was deregulated back in 2012, which resulted in many new providers entering the local market, many South Australians are now starting to switch providers. This is evident by Tier 2 retailer, Engie, overtaking EnergyAustralia to capture almost 9% of the SA market, albeit still a far cry from the market share of AGL and Origin.

The energy market went through a significant change in July 2019 when tough new industry regulations took effect, designed to cut power prices, but also make comparing plans easier. After years of big, often dodgy discounts, retailers must now compare their plans to a ‘level playing field’ tariff called the reference price. The idea is that, unlike before, there is now a consistent price from which all plans must now be compared, meaning you can now get a better feeling for which providers really offer the best value. The reference price also acts as a price cap for those customers who were previously paying the highest prices. Households who were on ‘standing offers’ prior to this date were automatically switched over to the Default Market Offer (DMO).
