Compare Cheapest Electricity Prices in SA

Fact Checked Fact Checked

South Australians are slugged the highest electricity prices in the country, which is why it’s hugely important to compare plans and make sure you’re getting the best deal possible. This means understanding electricity discounts and how they impact your overall costs. To help you find a cheaper plan, we have compared costs from some of the biggest electricity providers in SA and show what you can expect to pay with each of them.

Before we compare prices, it’s important to make the point that, if you have not switched electricity providers in the last couple of years, then you are almost certainly paying more than you need to. This is because new customers can benefit from often generous electricity discounts which have short benefit periods of usually just 12 months. After this time, you will start paying the higher rate, meaning that to get the best deals, you need to be willing to switch every year or two, otherwise you’ll end up paying the ‘lazy tax’.

*Price assumes general energy usage of 4000kWh/year for a residential customer on a single rate tariff. Estimated price includes any conditions discounts that may be available. Pricing based on SA Power network in Adelaide, but prices differ between distribution areas. October 2021.

^The Reference Price is set by the Australian Energy Regulator (AER) for a financial year in relation to electricity supply to residential customers in the distribution region and is based on an assumed annual usage amount. Any difference between the reference price and the unconditional price of a plan is expressed as a percentage more or less than the reference price. The terms of any conditional discounts are shown, along with any further difference between the reference price and the discount applied if a condition is met, expressed as a percentage more or less than the reference price.

As you can see, based on this comparison, Elysian Energy, ReAmped Energy and Discover Energy work out to be the cheapest electricity providers in South Australia. Overall though, this comparison does paint a rather bleak picture about electricity costs across the board in SA.

About the 3 cheapest deals

Now that the above table has shed some light onto what you can expect to pay for electricity from each provider, it’s time to find out more about the three cheapest plans available in SA. In the tables below, we compare prices on the SA Power network in Adelaide. We show one product per retailer, listed from the lowest priced estimate first. See here for information on the Reference Price, which in this comparison assumes general energy usage of 4000kWh/year, meaning the Reference Price is $1,716/year. Use our comparison tool for a specific comparison.

Power Maximiser (Elysian Energy)

After a re-shuffle of its product line-up, Elysian Energy has launched its latest product offering, Power Maximiser, in South Australia. However, this product isn’t like any other you’ll see on the energy market, with customers paying a monthly subscription fee as opposed to general and daily usage charges. The subscription fee also covers the first 250kWh of energy used within the month, but don’t fret if you go over! You’ll simply be charged the additional energy usage at a competitive, low rate.

Advance (ReAmped Energy)

ReAmped Energy is offering South Australians massive savings with its prepaid electricity option. Pay in advance every two weeks by direct debit and receive a whopping 25% off the reference price.

Smart Saver (Discover Energy)

Discover Energy’s market offer, Smart Saver, gives customers a guaranteed discount plan, with low variable rates and no exit-fees or lock-in contracts. This retailer is notorious for greener practices though, and customers must sign up to e-billing in order to be eligible for this plan.

How energy discounts impact your bill

Energy discounts were once the main marketing tool of the energy retailers, but following regulatory changes to the industry in July 2019, most have moved away from discounts and instead now focus on just providing cheaper base rates instead, as well as other incentives like bill credits. However, some retailers do still market discounts, which will typically now apply to both usage and supply charges. Discounts are typically available for paying bills on time or by direct debit. Some providers will also give you money off if you agree to receive bills via email instead of post. However, be aware that failing to meet the terms of your discount will not only mean you could lose the benefit, but you could also be charged a fee. Therefore, customers who struggle to pay their bills on time may find better value from electricity plans with lowest base pricing.

The other thing to be aware of in regards to energy discounts is the benefit term. Being able to lock-in a good discount for a couple of years represents a good deal. But no matter how long the benefit period, make sure you pay attention to when it disappears because it may not return and you’ll be left paying more.

Other Incentives

Also be conscious of sign-up incentives. It’s common for the energy companies to offer a rebate on your first bill when you sign up online, for example. Others have rewards programs whereby customers can get money off things like movie tickets. AGL offers flybuys points on the money you spend on bills, Simply Energy has a plan that brings ‘free’ movie tickets and Lumo Energy has a program that brings discounts at various retailers. While fairly attractive, it’s probably best not to let these incentives dictate your final decision, but they can be a good point of difference if you find two similar plans.

Tiered electricity pricing in South Australia

In South Australia, most electricity providers structure their plans with tiered pricing. This means you will be charged for power at different rates depending on how much you have used throughout the day. For example, you will typically pay lower prices for the first ‘block’ of electricity you use, but then a slightly higher rate for each next block. Our cost comparison has taken these block rates into account. While some providers only have two tiers of electricity pricing, others have as many as five.

Tiered pricing is another important consideration when comparing prices, so get to know your household’s specific electricity requirements, because the cheapest plan for you may be different to the cheapest plan for another household with higher or lower energy requirements. You can learn more about block rate pricing in our review of South Australia electricity tariffs.

SA Electricity Rates Example

Questions to ask:

get the best deal on energy in SA

It’s important to regularly reviewing your electricity plan to make sure you’re getting the best possible deal you can. No one wants to switch electricity providers every year, but the reality is that it takes effort to get the best deals and that’s what you might need to do. Here are some questions to consider and potentially ask when comparing electricity prices in South Australia.

  • Are you offering me the plan with the lowest usage rates?
  • How much are the supply charges and how do they compare to other plans?
  • How does the plan compare to the Reference Price?
  • Is there a contract? How long is it? Are there any exit fees if I leave?
  • What discount can I get off my bill and how do I quality for the discount?
  • What is the benefit term of the discount? Will it disappear after a year?
  • Can you offer me any additional sign-up incentives?

Ultimately, you should try to get to know your energy plans. No one is going to come round your house and offer to take $200 off your annual bill. Be proactive, compare plans, and consider switching if you think you can find a better deal.
