This guide will explore pricing, plans, discount opportunities and government rebates to get you paying less on your energy bill.

Why Electricity Prices Differ Tariffs in Adelaide & SA

Electricity rates may differ on parts of South Australia including Adelaide based on distribution areas, the electricity network company and even the retailer, or what is known in the industry as "energy plans", and a household's usage from neighbourhood to neighbourhood. Generation costs, network costs, retail margins and green scheme charges all add to the variability in pricing of the cheapest electricity Adelaide.

The DMO & reference price benchmarks in Adelaide / SA Power Networks

The DMO price for SA Power Networks for 2025–26 is determined as follows. $2,301 (for residential customers who do not have controlled load) for 4,000MWh per annum based on usage cost of supply to be increased incrementally each year by $71 (3.2%).

For regulated low-voltage household customers, the cheapest electricity Adelaide DMO price is $2,824 for 4,200 KWh, which corresponds to a rise of $64 (2.3%). Small businesses without controlled load can expect a DMO price of $5,541 for 10,000 kWh, an increase of $189 (3.5%).

In dollar terms, in real (i.e. forecast inflation-adjusted) terms, the non-controlled load residential price goes up by $17 (0.8%) and the controlled load price goes down by $2 (-0.1%). Small businesses have an actual increase of $61 (1.1%). These numbers reflect various changes in nominal and real terms for the next pricing period.

Components of your bill

Your electric bill has multiple parts:

• Usage Charges (c/kWh): This is the price you pay for power. It is usually expressed in cents per kilowatt-hour (c/kWh).

• Supply (Daily) Charges: Fixed charges for keeping your connection to the grid, whether you use very little electricity or none at all. They normally charge by the day.

• Fixed Charges: Some plans contain other fixed costs for administration or moving and reading meters.

• Network/Distributor Charges: These help to meet the cost of transporting the electricity from power stations to your premises, and maintaining the infrastructure.

The Key Factors That Affect What You Pay

You have to pay X amount for the cheapest electricity Adelaide, but there are few factors that affect it. These factors include how much energy you use, the type of electricity tariff you’re on and whether or not you have solar panels or other energy-saving features.

Household Usage Level

How much you consume in your home also has a huge impact on the costs of electricity. There are three main types of households in Adelaide:

• Low consumption (below 2,500 kWh/year): A good plan for small homes or apartments that use very little energy.

• Medium consumption (2,500-5,000 kWh/year): Average-sized homes with medium energy needs for heating, cooling and appliances.

• High consumption (more than 5,000 kWh/year): For larger homes with strong energy use, such as those that have air conditioning or electric heat or that are occupied by several people.

The more you use, the higher your bill will be unless of course you’re on the cheapest electricity Adelaide provider with the lowest usage rates.

Tariff Types

There are different types of electricity tariffs available in Adelaide:

• Single-rate Tariff (Flat Rate): A simple, flat rate where you pay the same price per kWh no matter what time of day it is.

• Time-of-Use Tarrif (ToU): With this plan, customers can take advantage of unique rates based on time of day. Electricity is usually less expensive during off-peak hours (like late at night), and more expensive during peak hours (like in the morning or on evenings).

• Controlled-Load Tariff: Perfect for houses with electric hot water units, this tariff lets you run specific appliances such as a hot-water system on off-peak power.

Getting the right tariff for your usage can come close to halving how much you pay. If you use a lot of power during those peak hours, the time-of-use tariff may not suit you when looking for the cheapest electricity Adelaide.

Solar Panels & Feed-in Tariffs

Having solar panels is one of the best ways you can help save the DMV on electricity. You can not only generate your own electricity, but also receive payment via feed-in tariffs for the extra solar power you export back to the grid.

• Solar Feed-in Tariffs (FiTs) : These differ among the retailers and are affected by wholesale price of electricity, and the degree of market competition. Some retailers pay higher FiTs so you could earn more for what you export.

• Battery Storage: A home battery can store excess solar electricity that you use during high peak rate periods, which are more costly.

Contract Type

You will also want to think about the type of plan you opt for when comparing electricity plans to find the cheapest electricity Adelaide:

• Fixed-rate Contracts: You sign up and receive the same rates for a time, giving you protection from increases in prices.

• Variable-rate Plans: As you might guess from the term, these plans can change every month and will likely save you money when you’re using energy during off-peak periods but give you no protection against price increases.

• Market Offers: These are usually priced lower than the DMO and change depending on your usage, discounts, and other considerations.

Discounts and terms of the contract are also significant. Some plans will provide a discount in certain conditions, such as paying on time or electricity being paid for through direct debit.

Current Electricity Providers and Plane (Adelaide / SA)

As you explore the cheapest electricity Adelaide options, it is important to understand the premier providers and their leading rates. These are the cheapest electricity deals from the major retailers in SA Power Networks network, including their usage and supply charges as well as annual costs.

Top providers

The best electricity Adelaide has to offer for one individual household may not be the best electricity Adelaide can provide to another household. It all depends on how much they use. A high usage family may be best served with a plan that has lower usage rates and low supply charges while a family that uses very little power might discover that the lowest daily supply charge will offer them the cheapest electricity Adelaide.

You Only Need to Save This Much Based on Your Profile

The estimated annual cost is intended to provide a useful benchmark, but actual savings will vary with your profile, including whether you are in a household that uses more or less energy. Here are some instances of how securing the cheapest electricity Adelaide plan could turn into actual savings in your own pocket.

Low consumers household (~2000-2500 kWh/year)

If you’re single or are in a small household that uses very little energy, then your usage is probably on the lower side. For you the most important part of the bill is the daily supply charge since it accounts for a greater percentage of your overall charges.

Let’s say you are on a standard offer plan with an elevated daily supply charge. By swapping to a cheapest electricity Adelaide plan such as ENGIE’s, which features a very low daily charge of 99.02c, you could seriously cut down on your annual bill. For you, the best value electricity Adelaide plan would focus on a low daily supply charge over the usage rate.

Medium Use Household (~4000-5000 kWh)

For you the usage fee is increased in importance. A low usage plan can save you hundreds of dollars every year. Let’s say your current plan is 45c/kWh, that would be pretty typical. Moving to a Momentum Energy plan with a 35.31c usage charge could result in $388 savings per year on usage only, not including the daily supply charge reduction. The best and cheapest electricity Adelaide will have for you is a balanced plan that provide competitive rates in both usage and supply.

High usage / including air conditioning / large house.

The usage charge is everything for a large home with many energy-hungry appliances. When looking for the cheapest electricity Adelaide can offer, it's all about getting down to prices with low cents per kWh! In such a case, a one-cent difference adds up to hundreds of dollars saved per year. It’s here that a cheap daily rate plan, despite an abit more expensive usage rate, is probably the cheapest electricity Adelaide-based households can find.

Contracts, Discounts, and What To Watch Out For

There are often discounts in many cheapest electricity Adelaide plans. However, they may have conditions around them that could impact your savings. Knowing these terms can help you avoid surprise charges or make sure your plan is giving you the maximum benefit.

Conditional vs Unconditional Discounts

Discounts can offer big savings on your electricity bill, but not all discounts are the same. Conditional bonuses like the ones that come with paying on time, having direct debit or being part of some kind of program could look attractive but they may demand you to make a habit out of them. On the other hand, unconditional discounts on the cheapest electricity Adelaide are more secure as they do not come with conditions, but might not be as applicable or significant in general as conditional ones.

Exits, Benefit Periods, Rate Reduction Clauses

Review the exit fees, benefit periods and rate change provisions that may be in place before deciding whether to sign up for a new cheapest electricity Adelaide plan. Exit fees might be charged if you choose to change carriers before your contract expires, so it’s important to know how long you’re committed for when you sign on the dotted line. Equally, benefit periods typically also have a certain duration, beyond which your rates may increase while rate change clauses can enable the provider to hike your fees during the contract and into future.

Green Power Add-ons / Premium Options

Many suppliers have add-ons or premium options for environmentally friendly consumers to choose from a part of their electricity package. And while these add-ons can help you lower your carbon footprint by accessing renewable energy, they usually carry a higher price tag than standard plans. If you are contemplating either of the above options, ensure that the premium cost appeals to your wallet and track goals for securing a greener cheapest electricity Adelaide energy plan.

Government rebates, concessions & solar incentives

SA state government rebates

Energy Bill Relief

Solar Feed-in Payments

All eligible solar systems receive a retailer contribution. There is a set distributor feed-in tariff rate (44 cents/kWh) that systems need to have been connected by September 30, 2011 to receive. Your solar PV system will need to be compliant with applicable Australian standards, connected with an import/export meter and capacity limited to 10 kVA for single-phase dwellings or 30 kVA for three-phase ones. If you change retailers, contact your new retailer to make sure they will accept you as a customer and keep making payments for your feed-in. Check the eligibility criteria here.

Tips to Choose and Switch Wisely

Changing electricity plans can seem overwhelming, but it is among the easiest ways to save money on your power bills. With some research and the right tools, you can easily find the cheapest electricity Adelaide plan that more closely aligns with your household’s needs.

How to Compare Plans with Real Bills and Usage Data

You can’t simply compare advertised discounts to judge different cheapest electricity Adelaide electricity plans. The trick is to use your own energy usage data available on a recent bill. You’ll need to think about two primary costs:

• Daily Supply Charge: This is a fixed charge that every household pays to be connected to the electricity network, irrespective of how much power you consume.

• Usage Rates (cents/kWh): Simply put, these are the c ost per kilowatt-hour consumed. This rate can differ substantially between insurers and policies.

With this information you can give a comparison tool (whether ours or our competitors) your usage and get an estimate of how much a new plan will cost you per year. It’s far more reliable than just going by the headline price.

Use of comparison tools & gov’t sites

One of the best ways to discover the cheapest electricity plan is by using an independent government comparison tool. For people living in South Australia, the Australian Government-administered site is known as Energy Made Easy (EME).

Energy Made Easy is a free service which allows you to compare energy offers from different retailers in New South Wales, Queensland, South Australia, Tasmania and the Australian Capital Territory. To get some quotes you will need to enter your postcode and answer a few questions about your home or business.

Although EME doesn’t show you the rates for your current plan, it does provide a list of available plans from most retailers in your area, listing the cheapest electricity Adelaide option from your current retailer. To learn how these new plans compare with the one you have, pull out a recent copy of your energy bill and do the following:

• Look for your current rates on your bill. They tend to be on page 2.

• Check whether the rates on your receipt are inclusive of GST. EME rates are inclusive of indirect taxes (GST), so you need to make sure you’re comparing them on a level playing field.

• Check to your plan type. With some homes, you may have all of these plans combined at once. Others may offer only single flat rate, while still others might require “time of use” plans that include evening and shoulder (mid-peak) periods.

This will help make sure that you’re looking at the right type of cheapest electricity Adelaide plan to compare. For residents of other states, there are other government comparison tools you can use:

• Victoria: Victorian Energy Compare

• Northern Territory: Power and Water site

• Western Australia: Economic Regulation Authority site

How often to review/switch

Moving to a new cheapest electricity Adelaide energy plan, especially if you’re on a standard variable rate tariff or coming to the end of your fixed term, can be a good way to save, but it’s crucial to be well-organised. Before you commit, give this fast list a try:

• Obtain a Basic Plan Information Document or summary of the new plan. It will then outline the cost and length of the contract, charges/credits.

• Check in with your current provider to see if you will be charged a fee for exiting your existing plan.

• Learn what “cooling off” rights you have, and if you can change your mind within a certain time frame after signing up.

• Inquire if the prices of the new plan can be changed, or if there are already scheduled changes.

• Find out if there’s any concessions you can receive and what flexible payment arrangements (such as being billed monthly) are available.

After you make the decision to switch, connect with your new provider by phone using the cheapest electricity Adelaide plan name and ID. They will take care of the rest, including informing your old retailer. The switchover usually takes place at the next scheduled meter reading period, which could be as long as three months. If you’d like to make the switch earlier, you can request an early meter read, although there might be a charge. You will also receive a final bill from your previous retailer.
