Electricity and Gas in South Australia

South Australia is one of the deregulated energy states within Australia, allowing residents to switch and compare energy plans and regain control over the ever-increasing cost of energy in the state. To help you find the best plan and provider, and understand the state of the market within SA, continue reading below and learn more about electricity and gas in South Australia.
Default Market Offer (DMO) in South Australia
In South Australia, the Default Market Offer for residents connected to the SA Power network on a single rate tariff is $1,83 as of July 2020
When comparing energy plans and providers, you’ve probably seen the “reference price” or “Default Market Offer” mentioned. The DMO is the electricity tariff set by the Australian government, used to cap energy prices and help consumers compare energy plans. While the DMO was first introduced to help those paying the historic Standing Offer (no longer valid as of July 2019), it is not always the cheapest offer available.
The Default Market Offer helps energy consumers in two ways:
To protect consumers from exponential energy prices if they choose not to engage with the energy market and instead remain on the DMO. While the DMO doesn’t necessarily offer the cheapest energy rates on the market it does prevent energy providers from charging you more if you don’t qualify for, or choose not to subscribe to, a discounted Market Offer.
To inform consumers about energy plan prices and how much less (or in some instances more) expensive an energy retailers market offer is, compared to the standard offer. This is often shown as “X% off the Reference Price” in the details about an energy providers electricity plan.

Average energy bills in SA
South Australians report the highest average annual electricity bills within the National Electricity Market, though New South Wales isn’t too far behind. The average electricity bill in South Australia can cost households over $1,700 annually, even more for households with pools.
Even per kWh, South Australian energy rates are about 10c more than those in New South Wales with the average electricity rates for South Australia at about 36c/kWh. These numbers can seem big, but implementing energy-saving measures can keep you below average and lower your energy bills.
- Lower your energy consumption!
- Unplug appliances and devices when they aren’t in use, to avoid energy vampires zapping energy from your home
- Upgrade old appliances with star-rated energy efficient options that might cost more upfront but will save energy and money down the line
- Replace your old single-pane windows with more energy efficient double or triple pane windows
- Install insulated curtains and door stoppers to keep the heat and sun out during the summer, and inside during the winter
