Compare Cheapest Electricity Prices in SA

Fact Checked Fact Checked

To help South Australians find a cheaper plan, Canstar Blue has compared costs from some of the biggest electricity providers in SA to show what you can expect to pay with each of them.

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.

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’.

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. Simply Energy typically has a plan that brings discounts for members of a certain motoring club while Lumo Energy has a program that brings discounts at various shopping and dining locations. 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.

Questions to ask your energy provider

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.
