In South Australia, electricity is produced from both renewable and non-renewable sources. The National Energy Market distributes this electricity to providers who then sell it to customers like you.

With solar photovoltaic (PV) systems, residents can benefit from feed-in tariffs offered by providers. These tariffs allow you to sell excess solar power back to the grid, which is credited on your energy bill.

Since 2012, South Australia's energy market has been deregulated, allowing customers to compare and choose electricity and gas plans from various retailers. If you're interested in exploring your options, you can use our free energy comparison service to get a quote.

Beyond this, consider factors like discounts, usage and supply charges, and any associated fees in the available plans.

  • Consider your energy usage rates and supply charges, seeking plans with the lowest kWh rates and daily supply charges to reduce your overall bill.
  • Use the reference price as a comparison tool, ensuring it reflects similar energy usage for an accurate assessment of plan competitiveness.
  • Review your actual energy usage to compare plans effectively and find the most suitable option.
  • Choose a tariff that matches your consumption habits, such as single-rate, time-of-use, solar feed-in, or controlled load tariffs. Keep in mind that some tariffs may require a smart meter.
  • Check the benefit period of any introductory plans to avoid transitioning to a more expensive option once the initial period ends.
  • If you have solar panels, check the provider's solar feed-in tariff to understand how much you'll be paid for surplus electricity.

Who are South Australia’s cheapest electricity providers?

To discover the most cost-effective energy plans in South Australia and select the ideal option for your requirements, you should take into account several key factors:

  • Incentives for switching providers
  • Lowest usage rates available
  • Supply charges
  • Contract duration and associated exit fees
  • Qualification criteria for discounts
  • Duration of discounts (benefit terms)

It's crucial to note that energy usage varies among individuals in South Australia due to different living arrangements, such as single or couple occupancy, as well as diverse appliance usage that impacts electricity consumption.

Among the competitive options are:

Lumo Energy: Lumo Energy, a part of Snowy Hydro Ltd, is a major renewable energy producer in Australia.

Comparing gas plans in South Australia

Gas plans follow a structure similar to electricity plans. When comparing gas options, key factors to consider include:

  • Service and support: Consider the ease of applying or switching plans.
  • Billing and payments: Review billing frequency and online payment options.
  • Plan flexibility: Look for competitive solar feed-in tariffs.

To choose the right plan, evaluate your household's gas consumption. If usage is high, prioritise lower usage rates. For lower consumption, focus on lower supply rates.

Who are South Australia’s cheapest gas providers?

Gas customers typically have two contract options with their supplier: standard contracts and market contracts. Standard contracts have prices set by retailers but follow certain conditions set by law, including no contract period or exit fees.

Market contracts, on the other hand, are largely determined by retailers and often offer savings through discounts, with varying contract lengths and conditions. Generally, market contracts are more cost-effective, especially if you qualify for discounts. If you haven't switched plans recently, you might save money by switching to a new offer with incentives.

It's important to compare usage and supply charges as well as rates from different suppliers to ensure you're getting the best deal. If you feel you're paying too much for gas, you probably are, so it's worth exploring your options.
