Australian Electricity Rate Comparison Made Simple
Trying to choose an electricity plan in Australia can feel like you’re staring at a wall of confusing numbers. But a good electricity rate comparison really just comes down to a few key things. I'll walk you through the most important parts of your bill—like usage rates and supply charges—and explain the different tariff structures so you can find a plan that actually fits your life.
How to Find the Best Electricity Plan in Australia
Finding the right electricity plan isn't just about grabbing the cheapest advertised rate. It’s about matching what a retailer is offering to your real-life energy habits, where you live, and even the daily rhythm of your household. A proper comparison digs into the fine print, helping you find genuine savings and stop paying more than you have to.
When you know what makes up a plan, you can look past the flashy marketing and spot what’s actually good value. This guide will give you the tools to do exactly that.
Key Factors in Your Electricity Plan Choice
Before you start looking at specific plans, you need to get a handle on the main things that drive your final bill. Any decent electricity rate comparison has to weigh up these four elements:
- Your Usage Habits: When you use electricity and how much you use are the biggest pieces of the puzzle.
- The Tariff Structure: This is how your usage gets billed—is it a single flat rate, or does it change depending on the time of day?
- Your Location: Network costs and retailer competition mean that prices can be wildly different from one state to another.
- Contract Terms: You've got to check the details, like how long any discounts last, if there are exit fees, and what the solar feed-in tariffs are.
A classic mistake is getting fixated on the cents per kilowatt-hour (c/kWh) rate. A plan might look cheap with a low usage rate, but if it has a high daily supply charge, it could easily cost a low-energy household more in the long run.
Comparing Your Core Charges
Let's look at how these factors work together by comparing the two main charges you'll find on any bill. Getting your head around how they relate is the first step to figuring out what you’ll really pay. You can also play around with our savings calculator to see how different scenarios stack up with your own usage data.
| Charge Type | Description | How It Affects Your Bill |
|---|---|---|
| Usage Charge | This is the price you pay for every kilowatt-hour (kWh) of electricity you use. It can be a single flat rate or vary by the time of day. | This is the variable part of your bill. The more power you use, the higher this charge will be. |
| Supply Charge | This is a fixed daily fee just for being connected to the electricity grid. You pay it no matter how much—or how little—power you use. | This is the fixed part of your bill. A high supply charge can make a plan expensive, even if your usage is low. |
Breaking Down Your Electricity Bill: What Are You Actually Paying For?
Before you can even begin to compare electricity plans, you need to get your head around what you're actually being charged for. Every power bill, no matter the retailer, is built from two key parts. Understanding how they work together is the secret to seeing past the flashy marketing and finding a genuinely good deal.
Too many people get fixated on the usage rate alone, and that’s often a recipe for a costly mistake. The real decider is the interplay between these two charges and your household's unique energy habits.
The Usage Charge: Paying for What You Use
This is the one most people are familiar with. The usage charge is the price you pay for every kilowatt-hour (kWh) of electricity you consume, measured in cents per kilowatt-hour (c/kWh). It’s the variable part of your bill—flick on the air con, boil the kettle, or charge your phone, and you're adding to this total.
It's simple maths. If your plan's rate is 28 c/kWh and you chew through 15 kWh of power in a day, your usage cost for that day is $4.20 (28 cents × 15 kWh). It’s a direct reflection of your consumption.
The Supply Charge: The Cost of Staying Connected
The daily supply charge is a fixed, non-negotiable fee you pay every single day just for the privilege of being connected to the grid. It covers all the background costs of getting power to your home—maintaining the poles and wires, managing the network, and so on. This charge ticks over whether you use a tiny bit of power or a huge amount.
Think of it like the line rental for an old landline phone. You paid a set fee each month just to have the service available, completely separate from the cost of any calls you made. This is where retailers often hide the true cost of a seemingly "cheap" plan.
A super-low usage rate can look tempting, but if it's paired with a sky-high daily supply charge, it can be a real trap for households that don't use much power.
Finding the Right Balance for Your Home
The crucial part is figuring out how these two charges stack up against your specific energy needs. A big family with high energy consumption will probably save more by hunting down the lowest possible usage rate, even if the daily supply charge is a little higher.
On the other hand, if you're in a low-usage household—maybe a single-person apartment or a home with a solid solar and battery setup—your focus should be on finding the absolute lowest daily supply charge. For you, this fixed cost is a much bigger slice of the total bill.
Let's look at a quick comparison for a household that uses 10 kWh a day.
| Plan Feature | Plan A (The "Low Rate" Plan) | Plan B (The "Balanced" Plan) |
|---|---|---|
| Usage Charge | 25 c/kWh | 30 c/kWh |
| Daily Supply Charge | 120 c/day ($1.20) | 80 c/day ($0.80) |
| Daily Usage Cost | 10 kWh x 25c = $2.50 | 10 kWh x 30c = $3.00 |
| Total Daily Cost | $2.50 (usage) + $1.20 (supply) = $3.70 | $3.00 (usage) + $0.80 (supply) = $3.80 |
On paper, Plan A looks like the winner with its lower usage rate. But watch what happens if this household becomes more energy-efficient and drops its usage to just 5 kWh a day:
- Plan A's New Cost: (5 kWh x 25c) + 120c = $2.45
- Plan B's New Cost: (5 kWh x 30c) + 80c = $2.30
Just like that, Plan B becomes the cheaper option. This is exactly why you need to grab a recent bill and run the numbers against your actual energy consumption before you even think about switching.
Comparing Australian Electricity Tariff Structures
The tariff you’re on is probably the single biggest factor shaping your power bill. When you're comparing electricity rates, it's not just about finding the lowest number; it's about matching a tariff's structure to the rhythm of your household. Let's dig into the most common options and see where you fit.
This simple breakdown shows the core difference between a flat, predictable rate and a Time of Use rate that changes throughout the day.
The key takeaway here is pretty clear: a single rate offers simplicity, but a Time of Use tariff creates both a risk and an opportunity. It rewards households that can be clever about when they use their power.
To help you decide, let's look at the key differences between the most common tariff structures you'll encounter.
Comparison Of Common Electricity Tariff Structures
| Tariff Type | Pricing Structure | Best Suited For | Potential Pitfall |
|---|---|---|---|
| Single Rate | One flat price per kilowatt-hour (kWh), 24/7. | Households with unpredictable usage, or those who are home and using power consistently throughout the day. | You'll pay a premium for any electricity used during off-peak hours, missing out on potential savings. |
| Time of Use | Different prices for electricity based on the time of day (Peak, Off-Peak, Shoulder). | People who can shift heavy appliance use (laundry, dishwasher) to off-peak hours, often overnight or on weekends. | High electricity use during peak evening hours can lead to a surprisingly large bill. |
| Demand | Charges for total energy used (kWh) plus a separate charge for your highest usage spike in a set period. | Homes with high-power appliances that have predictable, short bursts of usage. | Unpredictable, high-power spikes can result in steep demand charges, even if overall energy use is low. |
Ultimately, the best choice hinges entirely on your lifestyle. A tariff that saves your neighbour a fortune could end up costing you more if your daily routines are different.
The Simplicity of a Single Rate Tariff
The Single Rate tariff is as straightforward as it gets. You pay the exact same price for every kilowatt-hour (kWh) of electricity, whether you're making toast at 7 AM or running the air con at 10 PM.
-
Who it's for: This is a good fit for households with unpredictable schedules or for those who are home and using appliances throughout the day. It’s a classic set-and-forget option if you value predictability over the potential to save a few dollars by juggling your usage.
-
The downside: The trade-off for simplicity is a missed opportunity. You can't save money by shifting your power usage to cheaper times. If everyone's out of the house during the day, you're paying the same rate as you would during the evening peak.
This tariff is often the default plan for many households, but it's rarely the most cost-effective if you have even a little flexibility in your daily routine.
Strategic Savings with Time of Use Tariffs
This is where things get interesting. With a Time of Use (ToU) tariff, the day is carved up into different blocks, each with its own price for power. If you’re savvy, you can find some real savings here.
The structure usually looks something like this:
- Peak: The most expensive time, typically in the late afternoon and early evening (e.g., 4 PM to 8 PM) when everyone gets home and turns things on.
- Off-Peak: The cheapest time to use power, usually late at night and into the early morning (e.g., 10 PM to 7 AM). This is the prime time for running the dishwasher or washing machine.
- Shoulder: A moderately priced period that acts as a buffer between peak and off-peak times.
The government’s free Energy Made Easy comparison tool is invaluable for this. It lets you filter offers by tariff type so you can see exactly what ToU plans are available in your area. Using an official tool like this means you see every market offer, not just a curated list from a commercial comparison site.
Understanding Demand Tariffs
Finally, we have the Demand Tariff. This is a more complex beast, and you'll typically only see it on bills for households with some serious power-hungry appliances, like ducted air conditioning or a large pool pump.
With this structure, you don't just pay for the total amount of electricity you use (your kWh). You also get hit with a separate fee based on your single biggest spike of electricity consumption during peak demand windows. It’s designed to charge you for how much strain you put on the grid at its busiest times.
The cost of electricity is a major household expense and it varies wildly across Australia. As of 2025, an average home using 4,200 kWh a year in NSW would pay around AUD $1,176 annually (at a flat rate of about 28c/kWh), not including daily supply charges. That same household in southeast Queensland, with a more competitive rate of 20c/kWh, might only pay about $840. Over in South Australia, where rates are highest at around 34c/kWh, that bill jumps to $1,428. You can find a deeper dive into these state-by-state differences on platforms like SolarChoice.
Why Your Location Determines Your Electricity Cost
When you start comparing electricity rates, one of the first things you'll notice is just how much prices can change from one state to another. A fantastic deal in Sydney might be a terrible one in Adelaide. Your postcode plays a massive role in what you pay for power, and figuring out why is the first step to knowing what a genuinely good deal looks like for you.
This isn't just about small fluctuations, either. The price you're charged for electricity is a direct result of local factors that are completely out of your hands, creating unique energy markets in every state and territory.
The Core Drivers of Regional Price Differences
So, why the big difference? It really boils down to three key factors that stack up to determine the final price you see on your bill.
- Network Infrastructure Costs: The poles and wires that get electricity to your home don't maintain themselves. In states with vast distances and fewer people, the cost to keep that network running is spread across fewer households, pushing up the daily supply charge you have to pay.
- Local Energy Generation Mix: What a state uses to generate power has a direct impact on wholesale prices. Regions with plenty of cheap renewables or older coal power stations often have lower underlying energy costs compared to those relying more on expensive gas.
- Retail Market Competition: Simple supply and demand. The more energy retailers there are fighting for your business in a particular area, the more competitive their prices will be. More competition usually means better deals for customers.
One of the biggest mistakes people make is comparing their bill with a friend's in another city. An offer in Sydney just isn't comparable to one in Brisbane because the fundamental costs are completely different. You always need to benchmark a plan against what's available in your specific distribution network.
Take New South Wales, for example. The average cost there sits around 32.51 cents per kilowatt-hour (c/kWh), but you can find plans as low as 26.40c/kWh or as high as 37.27c/kWh. This is a world away from South Australia, which often has some of the highest prices in the country due to its unique combination of network costs and energy sources.
These regional price differences don't just affect what you pay; they also change how much you can earn from solar and batteries. The value of the energy you export to the grid is tied directly to local market conditions. You can see just how much this varies by looking at realistic VPP earnings in Australia based on your state, which really brings home how much location matters.
If you’ve got solar panels on your roof or just a passion for sustainability, a typical electricity plan comparison just won't cut it. You're playing a different game. Instead of just looking at usage and supply charges, you need to dig into the plans designed to reward you for generating clean energy or supporting the green transition.
For solar owners, the number that matters most is the solar feed-in tariff (FiT). This is the rate, measured in cents per kWh, your retailer pays you for any surplus solar power you send back to the grid. A good FiT can seriously slash your electricity bills, but it's not the whole story.
Don't get dazzled by a high FiT alone. Retailers are masters of the give-and-take. It's common for them to balance a juicy feed-in rate with steeper usage charges or a higher daily supply fee.
It's a classic trade-off. A plan offering 15 c/kWh for your solar exports might look fantastic at first glance, but if it charges you 40 c/kWh for the electricity you pull from the grid after sunset, you could easily end up paying more overall.
Finding the Sweet Spot with Solar Plans
The real secret is understanding your own energy habits. Do you send a lot of solar power back to the grid during the day, or do you use most of it yourself?
- High Export Homes: If your solar system pumps out way more power than you can use while the sun is up, you should absolutely prioritise a plan with the highest FiT you can find. It's worth it, even if the usage rates are a bit higher.
- High Self-Consumption Homes: If you're using most of that solar goodness yourself—maybe you work from home or charge an electric vehicle during the day—then a lower usage rate and supply charge will probably save you more money in the long run than a top-tier FiT.
While comparing feed-in tariffs is crucial, remember that it's not the only way to earn from your solar system. To get the full picture, it’s worth exploring the differences between a standard VPP vs feed-in tariffs in our detailed guide, which breaks down how Virtual Power Plants offer another avenue for monetising your solar and battery setup.
Assessing Green Energy and Carbon Neutral Plans
What if you don't have solar but still want to do your part? That's where GreenPower and carbon-neutral plans come in. These plans let you support renewable energy generation by paying a small premium, which your retailer uses to purchase renewable energy certificates on your behalf.
When you're looking at these "green" plans, transparency is everything. The retailer should be upfront about what percentage of your usage is matched with GreenPower (this can range from 10% to 100%) and how they back up their carbon-neutral promises. Yes, these plans might cost a little extra, but for many people, the peace of mind and environmental impact are well worth it. It’s all about finding a plan that sits right with both your wallet and your conscience.
Your Action Plan for Comparing Electricity Rates
Alright, you've got the theory down. Now it’s time to roll up your sleeves and put that knowledge into practice. A methodical approach to comparing electricity plans is the only way to ensure you're getting a deal that actually works for your home, not just one that looks good on paper. This is your game plan for confidently navigating the market.
First things first, grab a few of your recent electricity bills. These are your most powerful tool because they hold the truth about your household's energy habits. You're looking for your average daily consumption (measured in kWh) and how it fluctuates with the seasons. This data is the baseline you'll measure every potential new plan against.
A Practical Comparison Checklist
With your usage history in hand, you can start hunting for a better deal without falling for flashy discounts that don't last. This process breaks down a complicated task into simple, actionable steps.
-
Start with Official Tools: Your first stop should always be a government-run comparison site like Energy Made Easy. They are legally required to list every single plan on the market, giving you a completely unbiased view of what’s out there.
-
Model Your Usage: Don't just look at the rates. Use the website's calculator to plug in your own consumption data. This will give you a real-world estimate of your annual bill and show you exactly how a Single Rate tariff stacks up against a Time of Use plan for your lifestyle.
-
Scrutinise the Details: Once you've got a shortlist of promising plans, it's time to dig into the fine print. How long does that introductory discount really last? Are there any sneaky exit fees? And if you have solar, what’s the feed-in tariff, and does it apply to all the power you export?
A classic mistake is getting fixated on one single number, like a super-high feed-in tariff or a rock-bottom usage rate. You have to look at the total estimated annual cost. That’s the only figure that combines usage rates, daily supply charges, and any solar credits into one number you can actually compare.
Understanding Market Dynamics
Finally, remember that the electricity market isn't static; it's constantly changing. Wholesale prices move up and down based on everything from weather patterns to renewable energy generation.
For example, in August 2025, the average spot price in the National Electricity Market fell to $90/MWh. That was a massive 40% drop from the year before, and in South Australia, prices were slashed by half. Keeping an eye on these big-picture trends helps you know when it’s a particularly good time to compare plans.

Frequently Asked Questions
Digging into the details of electricity tariffs often brings up a few common questions. Here are some straightforward answers to help clear things up.
How Often Should I Compare My Electricity Rates?
A good rule of thumb is to check your electricity plan at least once a year. The energy market is always shifting, and new, more competitive deals pop up all the time. Don't just set and forget.
You should also do a quick comparison anytime your household's energy use changes significantly. Things like installing solar panels, adding a home battery, or buying an electric vehicle are perfect triggers to review your plan and make sure it still fits.
Can I Trust Third-Party Comparison Websites?
Commercial comparison sites can be a useful starting point, but they shouldn't be your only stop. Always kick off your search with the official government-run tool for your state, like Energy Made Easy. These sites are legally required to show every single plan on the market, so you get the full, unbiased picture.
Use third-party sites to get a feel for what’s out there, but remember they often have commercial deals that can influence which plans they promote. Always double-check the details on the retailer's own website before signing up.
What Is the Difference Between a Standing and Market Offer?
A standing offer is a default, government-regulated electricity plan. Think of it as a safety net price—every retailer has to offer one, but it's rarely the most competitive deal available.
A market offer, on the other hand, is a retailer's competitive plan. These almost always come with better rates, discounts, or other perks. This is why actively comparing plans is so important; sticking with a standing offer usually means you're paying more than you need to.
