Jared Mullane

South Australians pay some of the highest electricity prices in the country, which is why it’s important to compare energy providers at least once a year. Compare plans on price and value by reviewing the electricity rates and if there are any other incentives, like discounts and sign-up credit.

Australia's Money Matchmaker matching you with your best loans across multiple lenders
Natural gas plans in South Australia come in two types of contracts - market and standard contracts. Most customers will be connected to a market contract, but if you haven’t switched plans or providers in a while, then you may be on a standard contract, which is generally not a very competitive product.

Understanding the SA energy market

In South Australia, the primary electricity distributor is SA Power Networks - responsible for maintaining the state’s energy grid, supplying energy to residents and restoring power in the event of an outage. In remote areas, electricity may be supplied from a different distributor.

Australian Gas Networks (AGN) is the natural gas distributor in South Australia, covering all major and metropolitan areas of the state. In regional SA, Liquefied Petroleum Gas (LPG) is available to residents and businesses via a reticulated gas network, whereas bottled LPG is also available to customers throughout the state.

Yes, if you’re a resident or small business owner in South Australia you can choose your own electricity or gas provider. Depending on where you live in SA, your options may be limited, but here are some areas where you should be able to pick from a range of energy providers:

  • Adelaide

  • Gawler

  • Hahndorf

  • McLaren Vale

  • Mount Barker

  • Mount Gambier

  • Port Augusta

  • Port Lincoln

  • Tanunda

  • Victor Harbor

  • Whyalla

Energy in SA with Money Matchmaker

What is the average electricity bill in SA?

In South Australia, the average electricity bill is $1,707 a year, according to an estimate by the Australian Energy Market Commission (AEMC). The AEMC’s latest report showed that annual electricity bills are expected to decrease to $1,707 in 2023-24 from $1,742 in 2020-21.

What is the average gas price in SA?

South Australians pay an average gas usage rate of 5.64 cents per MegaJoule (MJ) and 89.7 cents in daily supply charges at a residential address on a single rate tariff, according to Money.com.au’s latest analysis.

The actual cost you will pay for gas will depend on multiple factors, including how much your property consumes, the rates you’re charged and if they’re charged in blocks. Some gas suppliers in SA will charge gas usage in ‘blocks’, meaning you’ll be charged a different rate for the amount of gas you use.

Check the Basic Product Information Documents or review your plan’s contract for a full list of the gas rates and charges.

How we calculated the average gas price in SA

This table below shows a selection of energy providers offering some of the cheapest gas rates in South Australia. These rates list the usage and supply rates for a specific postcode (5000) within the AGN distribution network in Adelaide, SA. Use the comparison tool at the top of this page to compare plans based on your postcode. This table lists usage rates and supply charges from five major gas suppliers in SA.

How to find the best energy plans in SA

To find the cheapest energy plans in SA and choose the best deal for your needs, you can consider the following factors:

  • Low usage rates and daily supply charges

  • Incentives for switching, such as a discount or sign-up credit

  • Benefit period of the contract, including how long you’ll receive the incentive(s)

  • No exit fees or hidden charges for paying a certain way

No two households are the same in SA and everyone uses energy differently. It’s worth considering your personal circumstances to identify what’s most important to you. For example, you may prefer to pay slightly higher rates in exchange for better customer service.

There are currently 20+ energy providers selling electricity to households and small businesses across South Australia.

FAQs about comparing energy in SA

Comparing energy plans in SA is easy and will only take a few minutes. Simply use a comparison tool (like the one at the top of this page) and input your details. From here you’ll be able to compare a range of energy providers in your area.

To find the cheapest electricity prices in Adelaide you’ll need to compare a range of deals from multiple energy providers. You can compare the overall annual cost of each plan and how it stacks up to the Reference Price, then you can dive a little deeper and review the usage rates and supply charges. Finally, check to see if there are any discounts on offer.

South Australia has more than 20 energy providers to choose from, some of which will appeal more to some customers than others. For instance, you may just be looking for the cheapest electricity prices, whereas your neighbour may be after discounts or access to a rewards program. Ultimately, the best energy provider in SA will depend on your personal circumstances.

Electricity bills in SA are expensive because they include three core components - energy generation costs, network charges (transmission and distribution costs), and retail costs to provide a service to your address. The size of South Australia compared to its population is also a contributing factor, as the grid needs to cover a large geographical area, according to the South Australian Business Chamber.

Once you’ve compared electricity and gas plans in SA, the next step is to choose an energy retailer who offers the best plan for your needs. After you’ve made your decision, making the switch should be relatively simple:

  • Apply and switch to a new provider

  • Your new provider should cancel your existing contract with your old provider

  • Receive confirmation of the change

Yes, renters in SA should be able to change energy retailers so long as the electricity or gas supply isn’t included in their rental agreement. If this is the case, the landlord of the property will be responsible for the energy service at your rental property.

Switching energy providers in SA can take as little as two business days, but this will depend on the type of meter at your property. Once you’ve switched providers, your new power company should provide you with an estimated timeframe of when your energy account will be transferred.

The good news is that most retailers in SA don’t apply exit fees to new market offer contracts, and these breakaway charges are largely a thing of the past. That being said, it doesn’t hurt to confirm there are no exit fees on your energy plan before making the switch. You can find this information on your current plan’s contract.

Energy retailers in SA are constantly revamping their market offers to encourage new customers to switch. One of the ways retailers entice customers to switch to them is by offering discounts, some of which may include:

  • Pay on time discount: A percentage off the usage portion or the entirety of your bill. This is the most common type of energy discount, and simply requires you to pay your bill on the specified date.

  • Direct debit discount: A small deduction for choosing to pay your bills by direct debit. Most retailers encourage direct debit payments as it means less admin for them.

  • Bundled energy discount: A discount for bundling your electricity and gas with the same energy supplier.

  • Email billing discount: A small fee waived on your bill for receiving bills electronically, as opposed to via the mail.

  • Unconditional discount: Known as a ‘guaranteed discount’, where a percentage is automatically taken off the usage charges or the entire bill during the benefit period.

If there is an incentive to do so and the rates of both electricity and gas are low, then bundling your energy can be a great way to save. Although it is convenient to have your utility bills sent from the same SA energy provider, just make sure you’re getting a good deal when you compare them separately to other electricity and gas deals in the market.

If you’re in SA and have solar, many energy providers offer plans with solar feed-in tariffs - a small rebate for exporting electricity back into the grid. Solar feed-in tariffs vary between retailers as do the usage rates and daily supply charges, so it’s important to review all the components that’ll make up your bill before making a decision.
