Despite widespread announcements of falling Default Market Offer (DMO) and Victorian Default Offer (VDO) electricity prices from 1 July 2026, many Australian households and small businesses are now receiving July bills that do not reflect the expected savings. While wholesale electricity prices have plummeted, some energy retailers are reportedly increasing daily supply charges on market offers, potentially offsetting any reductions in usage rates for their customers.
This creates a perplexing situation for consumers who were anticipating relief after the Australian Energy Regulator (AER) and the Essential Services Commission (ESC) finalised their default price determinations for the 2026-27 financial year. The discrepancy highlights the complex interplay between regulated default offers, underlying wholesale costs, and individual retailer strategies in a competitive market.
Wholesale Prices Plunge Amid Renewable Surge
New data from the International Energy Agency (IEA), released on 23 July 2026, confirms a significant drop in Australia’s wholesale electricity prices. The IEA’s Electricity Mid-Year Update 2026 reported that average wholesale prices in the National Energy Market (NEM) fell by 30% year-on-year in the first half of 2026, reaching approximately AUD 73/MWh (USD 49/MWh). This substantial reduction is primarily attributed to a surge in renewable energy generation and expanding battery storage capacity. The IEA noted that new battery capacity tripled daytime-to-evening energy shifting in Q1 2026, mitigating price surges by reducing reliance on more expensive gas and coal generation during peak hours.
This positive trend in wholesale costs was a key factor underpinning the AER’s and ESC’s decisions to reduce default electricity prices for the new financial year.
Default Market Offers Fall, But With Caveats
From 1 July 2026, the AER’s DMO 8 determination saw prices for residential flat rate standing offers decrease across New South Wales and South East Queensland. Households on these plans in NSW experienced reductions between 3.4% and 5.0%, equating to annual savings of approximately $66 to $137. For residential time-of-use (TOU) customers in NSW, reductions ranged from 3.7% to 7.7%, saving $72 to $211 annually.
South East Queensland saw the most significant residential price cuts in DMO regions, with flat rate standing offers dropping 7.2% (around $155 per year) and TOU plans decreasing by up to 10.7% (around $229 per year).
Small businesses in these regions also benefited, with reductions ranging from 9.0% to 20.9% in NSW and 10.4% to 14.0% in South East Queensland, depending on their tariff type.
Conversely, South Australian residential flat rate standing offers saw a modest 1.4% increase, adding approximately $33 annually. However, SA residential TOU customers received a 1.1% decrease (around $25 annually), and small businesses in SA saw cuts of up to 12.1% (around $673).
In Victoria, the Essential Services Commission (ESC) announced a 5% average reduction in the Victorian Default Offer (VDO) for households, saving around $84 annually, and a 6% average reduction for small businesses, cutting $241 from their annual bills.
“This is a positive outcome with prices coming down for the majority of households and all small businesses across the three regions where the DMO safety net applies,” AER Chair Clare Savage said regarding the DMO 8 determination.
Retailer Tactics: Rising Daily Supply Charges
Despite these falling default prices and the broader wholesale market trends, many Australians on competitive market offers are reportedly seeing their bills remain stagnant or even increase. This is largely due to a shift in retailer pricing strategies, with several major providers adjusting their market offers from 1 July 2026. Reports indicate that companies like AGL, EnergyAustralia, Momentum, Alinta Energy, and Origin have increased their daily supply charges, particularly in NSW and Queensland.
For example, while usage rates (cents per kilowatt-hour) might have decreased, a significant rise in the fixed daily supply charge (cents per day) can negate these savings, especially for households with lower overall energy consumption. This structural change means a lower ‘headline’ usage rate does not always translate to a lower total bill.
Furthermore, some solar customers have been impacted by reductions in feed-in tariffs. For instance, AGL’s standing offer solar feed-in tariff has reportedly decreased to 0c/kWh in some regions, while Momentum Energy and EnergyAustralia also cut their FiTs for market offers in NSW and QLD.
The Solar Sharer Offer: A New Opportunity
Amidst these changes, a significant new initiative, the Solar Sharer Offer (SSO), was introduced from 1 July 2026 as part of the DMO reforms. This opt-in offer mandates eligible retailers to provide three hours of free electricity every day for smart meter customers in DMO regions (NSW, SE QLD, and SA).
During these periods, typically 11:00 AM to 2:00 PM in NSW and SE QLD, and 12:00 PM to 3:00 PM in SA, customers can use up to 24 kWh of electricity for free. This initiative aims to encourage households to shift high-energy consumption activities, such as running washing machines, dishwashers, or charging EVs, to periods of abundant solar generation. The SSO is available to both homeowners and renters with smart meters, regardless of whether they have solar panels installed.
What This Means for Your Bill
If you are on a standing offer, your prices should have automatically adjusted from 1 July 2026 in line with the DMO or VDO. However, if you are on a market offer, the changes are not automatic, and your bill may reflect different adjustments. The DMO and VDO serve as a safety net and a reference price, but competitive market offers often sit below these default rates.
To truly understand the impact on your household budget, it is critical to review your latest bill and compare your current plan against available market offers. Daily Energy News strongly advises consumers to use government comparison websites like Energy Made Easy to find the best deal for their specific usage patterns. Understanding your tariff structure, particularly the balance between daily supply charges and usage rates, is now more important than ever.

| Victoria (VDO) | -5% (~-$84) | N/A (VDO sets overall average) | -6% (~-$241) |
Note: DMO/VDO figures are based on typical consumption and represent a maximum price for standing offers. Actual savings on market offers may vary and are subject to individual retailer pricing strategies.
Australians are encouraged to actively engage with their energy providers or explore switching options to ensure they are not inadvertently paying more than necessary, especially as the federal Energy Bill Relief Fund concluded at the end of 2025.
