Electricity Prices in South Australia—Quick Overview

South Australia possessed very high electricity prices overall, mainly because of its dependence on gas-fired power and the cost used for distribution of its network.

Average Rates by Usage (c/kWh)

The electricity costs are different and dependent on the amount of power consumed and the time of the power consumption in SA. Most of the households are paying 28 to 45 cents per kilowatt-hour (kWh).

This is what you will be expected to pay:

• Low-usage households:

Households that consume low usage (below 2000 kWh per year) usually have higher costs per unit. Those are typically small apartments or houses with gas heat and cooking. The cost may be 40-45 cents per kWh.

• Households using medium usage:

Better rates are given to households with medium annual electricity consumption (2,000–4,000 kWh). This is true for most residential homes with electric hot water and other electric equipment. Prices will range from 32 to 38 cents per kWh.

• High Usage Households:

Households with high electricity use (over 4,000 kWh per year) typically receive the lowest rates per kWh. These are large residences or houses equipped with pool pumps, electric heaters, and a variety of technologies. You might calculate 28–35 cents per kWh.

Rates of usage vary with the time of day. Paying more during peak hours (usually 6 to 10 PM) and less during off-peak hours is something you are willing to do. Rates might range from 20 to 25 cents per kWh during off-peak hours to 45 to 55 cents per kWh during peak hours.

Average Yearly Electricity Bill

In South Australia, the majority of households spend between $1600 and $2200 a year on energy.

AEMC uses the lowest offers from every company in order to calculate average electricity bill prices. Then they multiplied that price by the average usage of each home to get the annual cost.

Depending on the average house size and type, we’ve arranged a table below. You can get an idea for the electricity bill of 2 people at home in South Australia or above.

With solar panels, you may cut your expenditure by 30–70%. Additionally, many solar-powered homes in SA spend $800–1200 annually instead of $1800–2200

How to Choose the Best Electricity Plans in SA

For the best electricity plans for your homes, you just not only need to find the lowest rates but also pay attention to the details and think of your own energy habits. 

What Matters the Most When Comparing Plans

1. Low Usage and Supply Charges

These are the two basic costs.

• Usage Charge (c/kWh): This is electricity in cents per unit. A reduced usage charge will help you more in case you consume a lot of power.

• Supply Charge ($/day): It is a daily constant charge. When you consume power only in small amounts or take frequent absences it may be better to have a lower supply charge rather than a slightly lower usage rate. Never stop comparing the two.

2. Easy-to-Get Discounts

Most plans offer huge discounts. And there are three main types of discounts you can get. The first one is pay-on-time discounts. These are normal and usually do not demand much to obtain provided you are organised.

You can also get direct debit discounts. These are more regular and simple ones provided you have automatic payments.

Conditional discounts may obligate you to use their service in a specific way, pay through a special method, use a certain minimum amount or even sign up for additional services. An unconditional discount is a discount you receive just by being a customer of theirs.

3. Feed-in Tariff (to Solar Customers)

The FiT is crucial when you have solar panels in use. This is the payment you get from the government for additional power that your solar system feeds into the grid (kilowatt-hour (kWh)).

If the FiT is greater, more savings would be gained by solar households. A few retailers provide considerably higher FiTs compared to other retailers, although they have relatively high general usage rates.

4. Exit Fees and Length of Contract

No long-term commitments are even getting popular and are very flexible. If you find a better deal soon you can change the provider at any moment without any penalty.

Fixed-duration contracts (e.g., 12 months or 24 months) may have a smaller initial rate but if you quit early you will get a fast termination fee. Just ensure that you are knowledgeable about the penalty before subscribing.

5. GreenPower or Carbon Offset Options

If environmental impact is of concern to you, always enquire about the provider if they have GreenPower-rated plans or carbon offset initiatives. GreenPower is the process that ensures that a portion or all of your electricity usage is generated by confirmed renewable energy producers.

Carbon offset plants are basically an investment that works to emit less greenhouse gas so by sponsoring initiatives that lower or eliminate an equal number of emissions elsewhere.

Rebates & Concessions to Lower Your Bill

A number of programmes are available in South Australia to enable households to minimise the cost of electricity. You can save hundreds of dollars a year with these rebates and concessions.

SA Households Available Rebates

Federal Programmes:

Energy Bill Relief offers direct credits on the bills sent to eligible households. This is an initiative available through Services Australia and automatically puts credits onto your electricity bill. This can be between $75 and $150 every quarter.

State Programmes:

• The Cost of Living Concession (COLC) assists eligible SA households to receive assistance with their electricity bills. This concession will offer a quarterly credit of about 200-300.

• People with medical illnesses that require heating or cooling for their medical condition are assisted by the Medical Heating & Cooling Concession. These deserving homes are provided with additional credits worth $200 to $400 per year.

• SA Energy Discount Offer provides automatic electricity bill discounts. And eligible homes receive a few percent discounts on their usage charges. This would help them save up to $300 a year.

• Then there is an Emergency Electricity Payment Scheme (EEPS). This scheme supports households that are unable to afford their electricity’s initial cost. The scheme gives the one-time payments to them to avoid being disconnected.

• If you want your home to be energy efficient, the Retailer Energy Productivity Scheme (REPS) is there. This offers refunds to energy-efficient homes for their upgrades and their appliances. The rebates they get are up to a value of $200 to $1000, according to the upgrade level.

Who's Eligible and How to Apply

Whether you are eligible or not depends entirely on your income or situation. Most of the programmes target low-income earners. Incomes below $50000-$80000 annually are considered low in Australia.

Seniors and pensioners are eligible to get various kinds of rebates. Families with kids can be eligible for some programmes too. Those individuals who are disabled or suffering from certain medical conditions are also on the list of special concessions.

You must visit the official South Australia Government Website or apply to Service Australia for the rebates. You have to show your source of income and identity and in some cases medical certificates. You can get numerous rebates that are automatically applicable in case your application is approved.

Ways to Reduce Your Annual Electricity Costs

You can reduce your electricity costs in a number of ways, including by choosing an appropriate plan and using power efficiently. These are the tried-and-true strategies used by SA households:

Make strategic use of smart metres and time-of-use planning.

Plan your usage, especially if you have a smart metre. Use the large appliances when prices are at their lowest, which is during off-peak hours. Use your dryer, dishwasher, and washing machine before 6 AM or after 10 PM

Cut standby power.

In the off-state, the majority of the appliances use electricity. TVs, PCs, and chargers all use electricity when they are in standby mode. To turn off many items at once, install power boards with switches. This will result in yearly savings of up to $100 to $200.

Install solar panels or batteries when possible.

Your electricity bill may be reduced by 30-70% using solar panels. A 6kW system can save $1000-1500 a year in sunny SA weather. Battery systems would allow you to accumulate the benefits of solar power to be used in the hours at night or peak hours.

Look at energy plans once every 6-12 months.

Offers provided by energy retailers change frequently. The rates are often better when a customer is new. Note that you should visit the comparative websites twice a year. However, switching takes up to 20 minutes and can save you hundreds of dollars.

Check online to compare the market.

Utilise a comparison website such as Energy Made Easy or Compare the Market. These government and business websites compare all the available plans. Enter your postcode and usage to get personalised results. Never avoid reading the small print and contract conditions.

There is a portable battery system called BLUETTI Apex 300. If you cannot afford to invest in a whole solar system, you can consider purchasing a high-capacity powered station like the BLUETTI Apex 300 solar battery. It is a highly adaptable alternative.

Backup Power When It Counts—the BLUETTI Apex 300

It's important to take unexpected situations or system instability into notice by finding the best deal on electricity. It is the most effective way to conserve energy. In South Australian summer, blackouts mostly hit in different localities or places. A home backup power system, like the BLUETTI Apex 300 is the one that you can use.

Not just a backup battery, Apex 300 portable power station is a clever, scalable energy solution made to function in real Australian houses.

• Significant Capacity and Power Output

You can power nearly everything in your home because of its 2764.8 Wh LFP built-in battery, which has 3840 W peaks and 7680 W (Power Lifting Mode). You can power air conditioners, refrigerators, microwaves, tools, and many other appliances.

• Industry-Leading Lifespan

Using a second-generation EV-scale LiFePO₄ battery, the Apex 300 can charge for more than 6000 cycles. If you use it daily, it can last up to 17 years. Compared to most rivals, like Jackery or EcoFlow, it has twice the duration.

• Innovative Solar Combination

For South Australians with rooftop solar, the Apex 300 is the perfect device since it uses the BLUETTI app to provide load shifting and reduction of peak hours. You can further lower your expenses because it will charge during low times and release during busy ones.

• Long-Term Use and Scalable

You can create a whole-home backup system by connecting three or more Apex 300s with battery modules. It has a combined 58 kWh capacity and 11.52 kW of power. For EV charging in off-grid locations that frequently experience blackouts, this would be the ideal option.

• Whisper-Quiet & Zero Transfer Delay

It is a cost-saving alternative power provider for those interested in solar feed-in tariffs. This dependable backup, the Apex 300 will keep you running and in command of what the grid may deliver.

Understanding the SA Energy Market

The National Electricity Market (NEM), which connects the eastern and southern states of Australia, is mostly composed of the South Australian energy market. Electricity is produced, transported, and exchanged in this market.

Principal features of the SA energy market are:

High Penetration of Renewables

More than 70% of the power produced in South Australia comes from wind and solar energy, and this number is predicted to rise in the near future. Price instability may occasionally result from this reliance on renewable energy because production is weather-dependent.

Associated with NEM

Additionally, SA has interconnectors to Victoria that allow power to be imported or exported, helping to stabilise the supply and influence pricing.

Retailer's Option

In a competitive market, the retailers can provide a range of plans and incentives, allowing South Australians to select their favourite power provider.

Smart Metres Time-of-Use:

Smaller smart metres are more prevalent which allow Time-of-Use (TOU) tariffs where consumer rates vary with the time of day and induce consumers to use energy off-peak.

FAQS

How do I compare and switch providers?

Compare your usage-based plans on the government Energy Made Easy site (energymadeeasy.gov.au). Existing retailers share details of how to contact your new retailer who will do most of the switching on your behalf.

Are there any exit or switch fees?

Most of the plans now do not have exit fees particularly variable rates or lock-in contracts. Nevertheless, another influence of market contracts is that they are fixed-term contracts so you may end up having an exit fee when you are switching before the expiry of the contract so read the terms carefully.

What’s the best plan if I have solar?

The most optimal plan integrates a high solar Feed-in Tariff (FiT) with the use of low levels and daily supply charges. Solar and battery owners may also find value in Time-of-Use (TOU) plans as long as off-peak/shoulder rates are low.

Should I bundle electricity and gas?

Bundling will provide one bill and sometimes promotional discounts. But usually it is better to compare the least expensive electricity and gas plans independently with various providers.

Can renters change their energy retailer?

Yes, even renters have the option to switch their energy retailer where the name appears on an electricity bill.
