We’re proud to have helped millions of Aussies look for a better deal.
Find out how to avoid getting zapped by bill shock.
South Australia. We’ve got the power sorry. I’m not just talking about the football team. We’re lighting the path to a greener future. Our energy system is now more than seventy percent renewable.
So why are we still getting zapped with energy bill shock? Compare the Market surveyed more than a thousand Aussies and found over half had been switching off to save when instead, they should be switching over. Turning off lights or using the aircon less could save you a dollar or two. But by far, the best way to save is by comparing energy plans to make sure you’re on a competitive deal. Yet almost 8% of South Australian households either don’t compare or have let their plan roll over onto the Default Market Offer, meaning they could be losing out on potential savings.
Our experts at Compare the Market have these tips to help you navigate different rates, tariffs, and discounts. Number one, keep your energy bills on hand. That way, you can compare plans based on your actual usage. You’ll get more accurate estimates to help you find good value.
Two, compare your electricity and gas separately. If you have both, purchasing separate plans from different providers will often work out cheaper. Number three, keep an eye out for the comparison percentage against the Default Market Offer. That’s the maximum price energy retailers can charge residents and small businesses on a standing offer.
The bigger the percentage, the better. But remember, some retailers may have other deals and bill credit offers on top of the discount.
And you don’t have to wait until your next bill’s due. Switching to a new electricity provider can take as little as two business days, which means you can potentially take advantage of your new rate sooner. Meanwhile, gas suppliers will change over from your next billing date. It’s quick, it’s free, and Compare the Market makes it easier than you could imagine. Avoid build shock and get comparing today with Compare the Market.
Our Head of Energy, Meredith O’Brien has a few tips for helping energy customers understand their bill and search for a suitable energy plan by comparing energy providers in Adelaide and South Australia.
When you compare electricity providers in SA, you can switch your electricity provider in as little as two business days (gas may take a little longer). Best of all, switching comes with no disruption to your energy supply.
Bundled energy plans may look simpler, but can actually cost you more. Our energy price comparison tool lets you search for separate electricity and gas plans with different providers. By choosing different providers you can search for the best energy provider in SA for both electricity and gas and take advantage of deals and discounts.
If you have solar power, you might receive further savings on your electricity bill by installing a solar battery which could power your home even when the sun isn’t shining. With the introduction of two-way solar charging in July 2025, you could receive more from your solar feed-in tariff by storing your solar power and exporting it to the grid when demand is high.
If you haven’t compared electricity or gas plans in South Australia, you could be paying more than you need to for energy.
Here are just a few reasons to compare energy providers in SA:
Both residential and small business customers are free to switch electricity and gas providers in South Australia; this means you could pay less for energy if you opt for a different provider or take advantage of other gas or electricity deals.
Always check the following if you’re planning on finding a new provider:
South Australia generates electricity using renewable and non-renewable sources. The National Energy Market facilitates the sale of this energy from generators to electricity providers, who then sell it to you as the customer.1
SA’s energy market is deregulated, meaning you can compare and choose electricity and gas plans from different retailers.
Over a third of homes in SA are equipped with rooftop solar panels.2 With solar photovoltaic (solar PV) systems, SA residents can take advantage of solar feed-in tariffs. Feed-in tariffs allow you to sell unused solar power you’ve generated back to the grid, which appears as a credit on your energy bill.
The cheapest energy provider for Adelaide and SA can vary frequently. While we have listed the cheapest electricity plans in Adelaide below, it’s important to understand that the availability of certain plans and deals may vary and can change often, and how much you pay will depend on your usage and daily supply charge.
By doing a gas and electricity comparison in South Australia as regularly as every few months, you can stay on top of the best deals.
In South Australia, SA Power Networks is the main electricity distributor, while Australian Gas Networks (AGN) is the primary gas distributor.
Distributors are responsible for transmitting gas and electricity to your home by maintaining pipes, meters, powerlines and poles. They don’t set the prices you pay; they charge providers for the electricity or gas service. Then, providers determine the supply and usage charges that apply to you as a customer.

The prices and information provided above are based on a house with two to three adults with no air conditioning, no controlled load or pool and in the postcode of 5000 and are accurate as of 6 March 2025. Data sourced from the Australian Energy Regulator (AER). Plans and prices are subject to change.
In South Australia, you’ll be charged for electricity through supply charges and usage charges. Supply charges go towards maintaining the network and transporting energy to homes and businesses. Usage charges are what you pay for the energy you use.
To understand your energy plan better, you could review your energy provider’s plan information document or check out our guide for reading your energy bill to understand what you’ll be charged.
The tariff you’re on determines how much you pay for your electricity. Your energy habits may suit a single rate tariff, or you could potentially save on your energy bill with a tariff that charges different rates depending on the time of day you use electricity.
As a customer in South Australia, the following electricity tariffs may be available to you:
Yes, there are electricity concessions in South Australia available for both electricity and gas. These concessions may have eligibility requirements, such as needing one of the following concession cards:
Read more about energy concessions that may be available to eligible SA residents.
There are numerous reasons why your energy costs could have increased, so it’s best to contact your energy retailer directly to talk about this. Factors that can contribute to a higher bill include:
Because everyone uses different amounts of electricity at different times and there are various providers across South Australia, there won’t be an average electricity bill that applies to everyone across the state. According to the Independent Competition and Regulatory Commission (ICRC)’s Retail electricity price investigation 2024-27, the regulated reference price (using the Default Market Offer) for Adelaide in 2023-24 was $3,374, the highest of any of the recorded cities.3
According to the ICRC, the average price for Adelaide residential customers in 2023-24 on a single rate tariff with an annual electricity usage of 6,500 kilowatt hours (kWh) was $3,246. For those on time of use plans, the average electricity cost was $2,871 a year.
