How does the electricity market work in SA?
South Australia’s electricity market has deregulated retail pricing, which makes it a little bit of a free-for-all (in a good way). Letting retailers decide what they want to charge for their plans means they’re always competing, and competition = potential savings for you.
But if you’d prefer something a bit more regulated, there’s the Default Market Offer (DMO) which is a comparison price set by the Australian Energy Regulator. The DMO is priced to be fair, but not necessarily the cheapest. You might see it called a standing offer contract, although you’re welcome to sign up for one sitting down.
At the end of the day, it’s your call whether you hop onto a standing offer – just check what’s available in your area first.
Why should I compare electricity providers in SA?
South Australia doesn’t hold back with its weather. Their scorching summers and toe-curling winters mean your electricity bill will likely get a workout all year long. If you find that your bills keep creeping up every quarter, comparing could be the simple solution.
But comparing your electricity plan isn’t just about snagging a better price – you could also score discounts, green energy options, and more flexible rates. Why walk away with the first plan you see when you can shop around to find one that leaves a little bit extra in your budget?

How much does electricity cost in SA?
Electricity retailers can set their own market prices, but the Default Market Offer (DMO) – which is a comparison price set by the Australian Energy Regulator – is a good benchmarking tool to help you weigh up how much your electricity costs. For the 2026-27 financial year, the DMO price for South Australia was increased slightly to $2,334 for residential residents on a flat rate with annual usage of 4000 kWh/year, an increase of 1.4% from the previous year.1Australian Energy Regulator – Default Market Offer 2026-27; final determination, p 16
And if you want to take in the whole bird’s-eye view, you can look at wholesale prices – one of the largest influences on the DMO’s price.
Wholesale electricity is basically the price retailers pay before they send it along to you. In the first quarter of 2025 (the latest official data available), these costs jumped to $98, from December 2024’s low of $81, but this was most likely due to the change of seasons.2Australian Energy Regulator – Data – state of the energy market 2025 – chapter 2 – National Electricity Market, figure 2.3 When looking at 2024, SA rose to the equal second most expensive state in the country for wholesale electricity costs at $132 per MWh. That’s a 28% increase from 2023, mainly due to low renewable output, network outages and more impacting the state.3Australian Energy Regulator – Data – state of the energy market 2025 – chapter 2 – National Electricity Market, figure 2.3
What does the future of electricity prices look like in SA?
If predicting electricity prices was easy, we probably wouldn’t have had to deal with the 2022 energy crisis. While there are no guarantees, there are some pretty good signs to be hopeful about.
And in SA, those signs are powered by the sun. The state loves relying on sustainable sources and is on track to hit 100% net renewables by 2027. It’s an ambitious goal, but it’s doable when you think about the sunny climate of South Australia and its growing number of solar and wind farms (plus some handy grid-scale solar batteries).
Need proof? Just think back to 1 October 2023, when rooftop solar met a whopping 99.7% of SA’s total electricity demand from 1:00 to 1:30 pm.4The Guardian – Hope for power bill relief as eastern Australia’s wholesale electricity price tumbles And a year later, in Q3 of 2024, SA had some of the highest levels of negative wholesale prices in the National Energy Market. Translation? So much solar power was being generated that there wasn’t much demand for electricity from the grid.
Of course, it’s not all sunshine and rainbows. SA was also one of the most volatile states in the same 2024 quarter, thanks to factors like market caps returning, chilly nights, low wind conditions and network outages. But even with all these ups and downs, SA saw one of the lowest average wholesale prices, with a 37% decrease from Q2 of 2024.5AEMO – Quarter energy dynamics Q3 2024, figure 10
So, while we can’t predict the future, one thing’s for sure: SA’s energy game is looking bright.

How do I choose an electricity provider in SA?
Finding a new electricity provider is like dating. That first date might leave you thinking you’re a match made in heaven. But once the honeymoon period is over, you might realise you aren’t gonna get the happily ever after you were hoping for. So, before you say yes, it could be worth knowing what you want, so you don’t get stuck in an electricity relationship that’s all take and no give.
Electricity rates
Think of your rates like the price tags on your electricity. There’s usually a fixed amount you get charged every day (known as a supply charge) and a usage charge based on how much electricity (or kWs) you use. Understanding your current rates can help you look for a plan that offers better value.
Fees
Depending on the electricity retailer, a variety of fees might turn up on your next bill. These can include late payments, paper bill charges or even disconnection and reconnection fees. While these fees likely won’t be on every bill you get, they can certainly add up over time.
Tariff types
Your tariffs can affect how much you have to pay each quarter. Time-of-use tariffs, for example, come with different rates depending on when you use power. In peak times, like in the early evening, the rates might be higher because there’s more demand, compared to late at night when most people are in bed. There are also single-rate tariffs, which have a flat rate, and demand tariffs, which look at how intensely you use electricity, among others.
If you’re on a time-of-use tariff, a smart meter will be a game changer. Unlike manual meters, these generally collect usage readings every half hour so you can get more accurate billing.
Solar feed-in tariffs
Solar isn’t just great for the planet; it can help your electricity bill too. The trick is in the feed-in tariffs. These are the rates paid to you for selling excess solar-generated electricity to the grid – sort of like a reverse usage charge. A higher feed-in tariff can mean more credit for you, but it might also come with higher usage charges.
You could also find more value from your solar system by using as much of that clean electricity as possible instead of relying on the feed-in tariff. But this all depends on your household’s usage patterns.
Discounts
While your electricity retailer may not have as many discounts as your local rug store, they can still be worth keeping an eye out for. Just be careful to get the full story on any electricity discounts, particularly the conditional kind. These are ones that need you to do something to unlock the discount, like paying by direct debit or on time. So if you do see nice-looking discounts just remember to see if there are any attached conditions and if they’re achievable for you.
Helpful tip
Getting the most out of solar isn’t just about chucking a few panels on the roof. You’ll want to set things up to maximise solar generation in the winter months when the sun is at its lowest. Ideally, having your panels face north-east to north-west with nothing blocking the light will be the best option. Tilting your panels a bit can also help them soak up more of those sweet UV rays.
It can also be worth your time to chat with a renewable energy consultant. They can help tailor your solar setup to South Australia’s sun patterns. And with feed-in tariffs where they are, investing in a battery to store extra energy could help you potentially pay off your system quicker.

Just remember that iSelect can only help you compare from a selected range of providers.
While these companies may sell you electricity – and some even generate it – there are a few other key players to be aware of. Distributors, like SA Power Networks, are the ones who keep the lights on by managing the infrastructure that delivers electricity to your house. Thankfully, you don’t need to pay your distributor directly. Any costs will already be baked into your bill, because who wants to be dealing with more bills?
What rebates and concessions apply in SA?
A great electricity plan can help you save, but rebates and concessions could help you save even more. In SA, there are a couple to watch out for, including:
Energy bill concession: If you’re on a low or fixed income and hold a valid concession card or get a Centrelink payment, you could get up to $274.85 per year to help cover your energy bills.2Government of South Australia – Energy bill concessions
Energy bill relief rebate: To help ease rising costs, SA households can get up to $300 a year.3Government of South Australia – Energy bill relief You don’t need to do anything for this; you’ll just see a nice little quarterly credit of $75 on your bill.
Cost of living concession: If you’re on a low or fixed income, you could get up to $255.60 for 2024–25 to put towards electricity bills, council rates and medical expenses.4Government of South Australia – Cost of living concession
What are the peak, off-peak and shoulder times in SA?
If your electricity plan has a time-of-use tariff, you’ll pay different rates for during different hours of the day. With rates being higher at peak times than off-peak or shoulder, it’s all about spreading your energy usage out to ease the grid during rush hour.
While the times can change, in most cases SA’s peak hours are from 6 to 10 am and 3 pm to 1 am. Off-peak falls outside this, from 1 am to 6 am. But what about the rest of the time? In SA, the period from 10 am to 3 pm is called the solar sponge (or shoulder) time, since houses with solar panels will collect more solar power and lower their bill during these hours.
