Why compare electricity and gas plans 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 gas and electricity retailers (also known as 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 the energy you use. 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 time of use tariffs. Smart meters are installed in many SA homes, allowing some customers to opt-in for time-of-use tariffs. These tariffs can charge you less during quiet, low-demand periods and more when electricity is in high demand.
  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 see if you can get a better deal.

How electricity in South Australia works

South Australia generates electricity using renewable and non-renewable sources. The National Energy Market sells this generated power to electricity providers, who then sell it to you as the customer.2

With solar photovoltaic (PV) systems, SA residents can take advantage of provider 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.

SA’s energy market has been deregulated since 2012,3 meaning you can compare and choose electricity and gas plans from different retailers. To see some options available, you can get a quote with our free energy comparison service.

How is electricity and gas in South Australia charged?

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.

Check out our guide for reading your energy bill to understand what you’ll be charged. Or see the cheapest electricity prices in SA.

The cost of electricity and gas in South Australia

South Australians are charged some of the highest electricity rates in the country.4 Numerous factors can affect the cost of electricity in South Australia, including:

  • Supply charges. These cover the cost of being connected to the electricity grid or gas network. These supply charges remain the same regardless of your energy use, but may vary depending on your plan and retailer.
  • Usage charges. Like supply charges, usage charges vary depending on the energy plan and provider. Along with paying for your connection, you also have to pay a rate for each kilowatt-hour (kWh) of electricity or each megajoule (MJ) of natural gas you use. With this in mind, SA households with higher energy consumption needs will pay more for energy.
  • Retailer discounts and sign-up credits. These discounts could help you save on your energy bills. Discounts are often subject to a benefit period, meaning you’ll either stop receiving discounts after an agreed period or your retailer will roll you onto a more expensive plan. You may also be eligible for conditional discounts, such as bill credits, where you must meet set criteria to receive the discount. Always compare the discounts on offer by different retailers, as they can vary.
  • Your plan’s tariff type. See below.

South Australia's electricity charges and tariffs explained

The tariff you’re on determines how much you pay for your electricity. You have a single rate tariff (i.e. rates that stay the same regardless of when you use electricity). Meanwhile, others could save on their energy bill with a tariff that charges different rates depending on the time of day you use electricity.

Types of electricity tariffs in South Australia

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 demand or the time of day. This is generally the most common tariff for SA homes.
  • Time of use. Retailers can charge you different prices 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 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 tariffs (where you’re charged extra during periods of high demand) may also be available, but are less common for residential customers.

Who are South Australia’s electricity and gas distributors?

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.

Frequently asked questions

Are energy concessions available in South Australia?

Yes, there are electricity concessions in South Australia available for both electricity and gas. To be eligible, you must:

  • 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
  • Not be living with someone earning more than $3,000 annually (unless they receive a Centrelink or Department of Veterans’ Affairs allowance or they’re your dependent, spouse or domestic partner).

Read more about energy concessions that may be available to eligible SA residents.

What's the best solar feed-in tariff in South Australia?

The best solar feed-in tariff available in South Australia will depend entirely on which electricity provider you’re with. According to the Essential Services Commission of South Australia, providers determine how much they credit to solar customers for the electricity they feed to the grid.

However, the state government stipulates the minimum a customer is set to receive – providers just confirm whether they offer the minimum or will offer more for energy your solar panels generate. Read your plan information document to understand which solar feed-in tariff you’re on.

Always compare your options to ensure you’re on a plan you’re happy with.

Can I switch electricity and gas providers in South Australia?

You 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 deals.

Always check the following if you’re planning on finding a new provider:

  • Whether there 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 any deals or benefits you can take advantage of if you switch

Why is my electricity or gas bill in South Australia so high?

There are numerous reasons why your electricity or gas bill in South Australia could be high, so it’s best to contact your provider directly to talk about this. Most commonly, bills are higher when people use more electricity or gas than they expected.5

Other factors that can contribute to a higher bill include:

  • The tariff you’re on
  • Your discount/benefit period has expired
  • Incurring additional charges, such as late fees or unpaid amounts from previous bills
  • Appliances ageing and becoming inefficient
  • Gas leaks

What is the average electricity bill in South Australia?

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 Australian Energy Regulator’s (AER) Annual Retail Markets Report: 2021-22, the median annual bill cost for the retail standing offer was between $1,984 and $2,071, and the average market offer was between $1,620 and $2,541.4

However, the Default Market Offer (DMO), which is a reference price to compare how much you can be charged for electricity and based on the average energy usage and supply charges, can help us understand what you might be charged.

According to the AER, the DMO in 2022-23 for people on the SA Power Network’s residential distribution network with annual electricity usage of 4,600 kWh is $1,840 a year.6 For those in distribution areas also on a controlled load of 1,800 kWh (electricity supplied to certain appliances such as hot water systems that operate in off-peak times), the DMO is $2,272 annually.
