Australian households are set to see varied changes to their electricity bills in 2026, with the Default Market Offer (DMO) and Victorian Default Offer (VDO) resetting on 1 July 2026. While most states will experience price decreases, South Australia faces a slight increase. To secure the cheapest electricity plan, actively comparing market offers against these benchmarks is essential, as competition among retailers remains robust, especially in deregulated zones.
The Australian Energy Regulator (AER) and the Essential Services Commission (ESC) in Victoria finalised their DMO and VDO determinations for the 2026-27 financial year, reflecting a significant drop in wholesale electricity prices. The average wholesale electricity price across the National Electricity Market (NEM) fell by 47% year-on-year to just $74/MWh in Q2 2026, driven by record renewable energy output and increased battery storage.
Understanding Your Electricity Bill in 2026
Before diving into comparisons, it’s crucial to understand the key components that determine your electricity costs:
- Default Market Offer (DMO): Set by the AER, the DMO is the maximum price retailers can charge residential and small business customers on standing offer contracts in New South Wales, South East Queensland, and South Australia. It also serves as a reference price for comparing market offers.
- Victorian Default Offer (VDO): Victoria’s equivalent to the DMO, set by the ESC, acts as a safety net for customers on standing offers and a benchmark for market offers.
- Market Offers: These are competitive plans offered by retailers, often with discounts, incentives, and varying tariff structures. They are typically cheaper than standing offers.
- Daily Supply Charge: A fixed daily fee charged by your distributor, regardless of how much electricity you use.
- Usage Charges (c/kWh): The rate you pay for each kilowatt-hour (kWh) of electricity consumed. These can be flat rates, time-of-use (TOU) rates, or block rates.
- Solar Feed-in Tariffs (FiT): Credits you receive for excess solar power exported back to the grid.
2026-27 Default Offer Price Changes by State
Here’s how the DMO and VDO changes, effective 1 July 2026, impact typical residential customers across the NEM states:
New South Wales
NSW households on flat-rate standing offers will see price decreases between 3.4% and 5.0% for 2026-27, depending on their distribution zone. For instance, Ausgrid customers will save approximately $66, Endeavour Energy customers $83, and Essential Energy customers $137 annually. Residential customers with smart meters on time-of-use (TOU) tariffs can expect even larger reductions, up to 7.7%.
Victoria
The Victorian Default Offer for 2026-27 has been cut by an average of 5% for residential customers, translating to an average annual saving of approximately $84 for a typical household consuming 4,000 kWh per year. Small businesses will see an average reduction of 6%, or about $240 annually. This reduction is primarily driven by lower environmental, wholesale, and network costs.
South East Queensland
Residents in South East Queensland (Energex network) on flat-rate standing offers will experience a 7.2% decrease, saving around $155 annually. TOU customers could see reductions up to 10.7%.
South Australia
South Australia is the outlier for residential flat-rate customers, facing a modest 1.4% increase in the DMO, adding approximately $33 to annual bills for SA Power Networks customers. However, residential TOU customers may still see a slight decrease of 1.1%.
“The DMO and VDO reductions are largely a result of significantly lower wholesale electricity prices in Q2 2026, which fell by 47% year-on-year across the NEM, driven by increasing renewable energy generation and battery storage.”
Finding the Cheapest Electricity Plan for Your Home
While the DMO/VDO provides a crucial safety net, market offers are almost always cheaper. To find the best deal, you need to compare plans specific to your postcode and usage habits.
- Gather Your Bills: Your recent electricity bills contain vital information: your daily supply charge, usage rates (c/kWh), and your average daily/quarterly consumption. This data is essential for accurate comparisons.
- Use Government Comparison Tools:
- Energy Made Easy: The Australian Government’s free, independent comparison website for NSW, QLD, SA, ACT, and TAS. It allows you to compare all available electricity and gas plans in your area.
- Victorian Energy Compare: For Victorian residents, this is the official state government tool to compare offers from all retailers.
- Understand Your Usage Profile: Are you a high daytime user (e.g., working from home, running air conditioning)? Or do you use most electricity in the evenings? This impacts whether a flat-rate, time-of-use (TOU), or ‘solar sponge’ tariff is best.
- Look Beyond the Headline Discount: Focus on the estimated annual cost for your typical usage, not just percentage discounts off a high standing offer. Check daily supply charges and usage rates carefully. Some plans offer low usage rates but high supply charges, or vice-versa.
- Check Contract Terms: Be aware of benefit periods, exit fees, and whether rates are fixed or variable. Most competitive market offers are variable, meaning rates can change with market conditions.
Competitive Market Offers in 2026
While specific ‘cheapest’ plans fluctuate frequently, several retailers consistently offer competitive market rates across states. Here are some indicative examples based on recent 2026 data for typical residential usage (note: prices are subject to change and depend on your network zone and specific usage):
| State | Network Zone | Retailer (Example Plan) | Estimated Annual Cost (Typical Usage) | Usage Rate (c/kWh) | Daily Supply Charge ($/day) |
|---|---|---|---|---|---|
| NSW | Ausgrid | Kogan Energy | ~$1,678 | ~25.2 | ~1.16 |
| Endeavour Energy | Tango Energy (Everyday Easy) | ~$1,769 | Varies | Varies | |
| Essential Energy | Tango Energy (Everyday Easy) | ~$2,063 | Varies | Varies | |
| VIC | CitiPower | GloBird Energy | ~$1,024 | ~17.3 | ~0.91 |
| Jemena | Sumo Power | ~$1,023 | ~17.4 | ~0.90 | |
| QLD | Energex | Lumo Energy (Shine Plus) | ~$1,759 | ~26.4 | ~1.21 |
| Gold Coast | Amber Electric (Battery + Solar) | ~$1,570 | Varies | Varies | |
| SA | SA Power Networks | Lumo Energy (Shine Plus) | ~$1,861 | ~28.1 | ~1.27 |
| SA Power Networks | Amber Electric (Battery + Solar) | ~$2,070 | Varies | Varies |
Note: ‘Estimated Annual Cost’ figures are based on specific benchmark usage assumptions (e.g., 410 kWh/month or 4,000 kWh/year for residential, no solar) and can vary significantly based on your actual consumption, postcode, and tariff structure. Always obtain a personalised quote.
Leading retailers like AGL, Origin Energy, and EnergyAustralia maintain significant market shares across NSW, VIC, and QLD. However, smaller, agile retailers like Red Energy, Alinta Energy, GloBird Energy, and Amber Electric are increasingly competitive, often offering innovative plans.
Leveraging New Offers: The Solar Sharer Offer
A significant new development for 2026 is the introduction of the Solar Sharer Offer (SSO). This opt-in standing offer is available to residential customers with smart meters in DMO jurisdictions (NSW, SEQ, SA). It provides three hours of free electricity in the middle of the day (11 am to 2 pm in NSW and SEQ; 12 pm to 3 pm in SA).
The SSO is designed to encourage households, even those without rooftop solar, to shift their electricity usage to periods of abundant solar generation, reducing demand on the grid during peak times and potentially cutting bills. While the free period is attractive, be aware that usage rates outside these hours may be higher than on a standard plan. It’s crucial to assess if your household can effectively shift a significant portion of its usage (e.g., running washing machines, dishwashers, or charging an EV) into this free window.
