Compare Electricity & Gas in South Australia

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:

1. Take advantage of market offers. SA households can compare market offers, which can include incentives, discounts or cheaper usage rates for energy. By comparing your current plan against others on the market, you’ll know whether it’s time to switch providers.
2. Make the most of available tariffs. Smart meters are installed in many SA homes, allowing some customers to opt-in for time of use tariffs. These tariffs charge you less during low-demand periods and more when electricity is in high demand. Time of use tariffs may also include demand tariffs, so it’s important to understand your energy use and household needs to check its right for you.
3. Weigh up your options. Not getting great value from your current energy plan? You can compare various options from retailers on our panel to search for a cheaper energy provider in Adelaide and South Australia.

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:

• Whether there are any exit fees you could be charged if you leave your current provider
• Your current rate and usage and if you’ll benefit by switching to a different provider
• If you’ll be on a variable rate (no lock-in contract) or a fixed rate (potential lock-in contract term) with your new provider
• If there are any deals or benefits you can take advantage of if you switch
• If Greenpower options are available to carbon offset your usage with renewable energy).

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.

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:

• Single rate. The single-rate tariff charges a flat rate for energy usage regardless of the level of demand or the time of day.
• Time of use. Retailers can charge you different rates for electricity depending on the time of day and day of the week. You could potentially lower your bills by implementing energy-saving tips during high demand or peak times and using electricity more in off-peak times. Retailers set these times, and they can vary.
• Controlled load. Metered separately from your main tariff, controlled load tariffs generally offer lower rates for household appliances with high energy demands, such as hot water systems.
• Demand. These tariffs may come in addition to your time of use tariff. If your plan has a demand tariff you may be charged extra during periods of high demand to discourage heavy electricity usage and ease the burden on the electricity grid.

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:

• Hold a valid concession card, such as a Pensioner Concession Card or Commonwealth Seniors Health Card
• Receive eligible Centrelink payments or parenting payments
• Be a resident of the property
• Be an account holder on the electricity or gas bill.

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:

• You’re using more electricity or gas than expected
• The tariff type you’re on
• Your discount/benefit period has expired and your gas or electricity rate increased
• You’ve incurred additional charges, such as late fees or unpaid amounts from previous bills
• Appliances ageing and becoming inefficient
• The number of people in your household increased
• Gas leaks.

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.
