Cheapest Electricity Providers in Australia
Australian households spend an average of $1,400–$1,800 per year on electricity, but the price you pay depends heavily on which retailer and plan you choose. The difference between the cheapest and most expensive provider in the same postcode can be $300 or more annually. With over 30 active electricity retailers competing in the National Electricity Market (NEM), there are genuine savings available for households willing to compare their options.
This guide compares the cheapest electricity providers in Australia for 2026, covering average usage rates, daily supply charges, and estimated annual bills based on typical household consumption of approximately 4,500–5,000 kWh per year. All figures are indicative and based on published rates across major distribution zones — for a personalised comparison based on your exact address and usage, use our free comparison tool.
Electricity pricing in Australia is regulated at the state level, with the Australian Energy Regulator (AER) setting the Default Market Offer (DMO) in NSW, QLD, and SA, and the Essential Services Commission (ESC) setting the Victorian Default Offer (VDO). These benchmarks cap the maximum price retailers can charge on their default plans, but competitive market offers are often 10–25% below these caps. Understanding how pricing works is the first step toward finding a cheaper deal. For more detail on our data sources, see our methodology.

Cheapest electricity providers by state
Electricity prices differ significantly across Australian states due to varying network costs, generation mix, government concessions, and the level of retail competition. States with more retailers competing for customers — such as Victoria and New South Wales — tend to have lower market offers. Below you can explore detailed pricing data for each state.
See all states on our electricity prices hub, or explore electricity plans by suburb.
Cheapest electricity plans by city
Even within a single state, electricity prices can vary by city depending on which distribution network serves your area. For example, a household in Western Sydney (Endeavour Energy zone) may see different rates from a household in the CBD (Ausgrid zone). The cities below are among the most-searched for electricity plan comparisons in Australia.
Why electricity prices differ across Australia
Australia does not have a single national electricity price. Instead, what you pay depends on a combination of factors that vary by location. Understanding these factors helps explain why the “cheapest” provider in one state may not be available — or competitive — in another.
- Network costs: The cost of transporting electricity through poles and wires accounts for roughly 40–50% of your bill. These charges are set by distribution companies (e.g. Ausgrid in Sydney, CitiPower in Melbourne) and vary between zones.
- Generation mix: States that rely more heavily on renewable generation (like Tasmania with hydro, or South Australia with wind and solar) have different wholesale cost profiles from coal-dependent states.
- Retail competition: Victoria has the most competitive retail market in Australia, with over 20 active retailers. More competition generally drives lower prices. By contrast, Western Australia and Tasmania have very few retail options.
- Government policy: Feed-in tariffs, renewable energy targets, concession schemes, and network investment decisions all influence the end price consumers pay.
- Tariff structure: Single-rate, time-of-use, demand, and controlled-load tariffs all produce different annual costs depending on when and how you use electricity.

How to compare energy plans and find the cheapest rate
Comparing electricity plans effectively requires looking beyond headline discounts. Here is a step-by-step approach to finding the cheapest provider for your household:
- Check your current bill. Find your current usage rate (c/kWh), supply charge (c/day), and total annual consumption (kWh). This gives you a baseline to compare against.
- Use a comparison tool. Enter your postcode and usage into a comparison service like EnergyPlans to see available plans ranked by estimated annual cost.
- Compare the total annual cost, not just the rate. A plan with a low usage rate but a high supply charge may cost more overall. Always compare the estimated annual bill.
- Check contract terms. Look for exit fees, benefit periods, and whether the rate is fixed or variable. A cheap introductory rate that reverts to a higher price after 12 months may not deliver long-term savings.
- Consider your tariff type. If you use most of your electricity during off-peak hours (evenings, weekends), a time-of-use plan may save you more than a flat rate. If your usage is spread evenly, a single-rate plan is simpler.
- Switch online. Once you have found a cheaper plan, switching is free and typically takes 1–3 business days. Your power supply is not interrupted during the switch.

- Who is the cheapest electricity provider in Australia?
- The cheapest electricity provider varies by state and distribution zone. In general, smaller Tier 2 retailers like GloBird Energy, Tango Energy, and Sumo Power tend to offer the lowest headline rates. However, the cheapest option for your household depends on your postcode, usage patterns, and whether you are on a single-rate or time-of-use tariff. Use a comparison tool to find the best deal for your address.
- How much does electricity cost per kWh in Australia?
- The average residential electricity rate in Australia is approximately 28–32 cents per kWh, though this varies significantly by state. South Australia and Queensland tend to have higher rates, while Victoria and New South Wales are generally more competitive due to greater retailer competition. Rates also depend on the time of day if you are on a time-of-use tariff.
- Is it worth switching electricity providers?
- Yes, switching electricity providers is one of the easiest ways to reduce your energy bill. Households that have not compared plans in the last 12 months are often paying more than necessary. Switching is free, takes less than 10 minutes online, and there is no interruption to your power supply. The average Australian household can save $200–$400 per year by switching to a more competitive plan.
- What is the difference between a usage rate and a supply charge?
- The usage rate (cents per kWh) is the cost of the electricity you actually consume. The supply charge (cents per day) is a fixed daily fee for being connected to the electricity network, regardless of how much power you use. Both charges appear on your bill. When comparing plans, check both the usage rate and the supply charge, because a low usage rate with a high supply charge may not save you money overall.
- Do electricity prices change every year?
- Yes. In most states, the Default Market Offer (DMO) or Victorian Default Offer (VDO) is updated annually, usually taking effect on 1 July. Retailers adjust their rates around this time. Wholesale electricity prices, network costs, and government policies all influence annual price changes. Comparing plans after each price update is a good habit to ensure you are still on a competitive deal.
- Can I compare electricity plans for free?
- Absolutely. EnergyPlans provides a free, independent comparison service. You can compare electricity and gas plans from major Australian retailers without any cost or obligation. Our data is sourced from regulated AER and ESC benchmarks, so you see transparent, unbiased results.
