Australian households and small businesses are now seeing the impact of the Australian Energy Regulator’s (AER) final Default Market Offer (DMO) 2026-27 determination, which took effect from July 1, 2026. The AER’s decision, released on May 26, 2026, promises electricity bill reductions for the majority of customers on standing offers across New South Wales, South East Queensland, and South Australia, with some small businesses set to save over $1,300 annually.
While the AER’s final determination was announced in late May, its implementation from July 1 means that the financial impacts are now actively being experienced by consumers. This DMO, which acts as a regulated price cap and a reference point for comparing market offers, also introduces the innovative Solar Sharer Offer, providing eligible households with three hours of free daytime electricity.
Significant Bill Reductions for Many
The AER’s 2026-27 DMO brings welcome relief after previous years saw sharp increases. Most residential and small business customers on standing offers will experience lower electricity costs.
Residential customers in New South Wales can expect flat rate standing offer prices to fall between 3.4% (approximately $66) and 5.0% (approximately $137). South East Queensland households will see a more substantial decrease of 7.2%, equating to around $155 annually. South Australia is the exception for residential customers, facing a modest increase of 1.4%, or about $33 per year.
For smart meter households on time-of-use standing offers, savings are more widespread. South Australian customers will see a 1.1% decrease (around $25), while New South Wales reductions range from 3.7% ($72) to 7.7% ($211). South East Queensland leads with a significant 10.7% decrease, saving approximately $229 annually.
Small businesses stand to gain the most. In New South Wales, flat rate prices will decrease between 9.0% ($432) and 11.3% ($705), with time-of-use tariffs seeing even larger reductions of 9.4% ($449) to 20.9% ($1,303). South East Queensland businesses will experience decreases of 10.4% ($445) for flat rates and 14.0% ($601) for time-of-use. South Australian small businesses will see reductions between 6.8% ($379) and 12.1% ($673).
“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,” said AER Chair Clare Savage on the release of the determination. “The reductions compared to last year reflect easing cost pressures in parts of the electricity supply chain and addresses industry and consumer feedback to ensure prices remain fair and workable in practice.”
The New Solar Sharer Offer
A significant reform within the DMO 2026-27 is the introduction of the Solar Sharer Offer (SSO). This initiative mandates retailers with over 1,000 customers in DMO jurisdictions to provide eligible smart meter households with three hours of free electricity in the middle of the day.
The free power window is set from 11 am to 2 pm in New South Wales and South East Queensland, and from 12 pm to 3 pm in South Australia. This offer includes a daily free usage cap of 24 kWh, which is sufficient to meet the needs of an average five-person household. Crucially, the SSO is available to homes even without solar panels, and to both homeowners and renters.
This opt-in offer aims to encourage households to shift their energy consumption to periods of abundant rooftop solar generation, thereby helping to stabilise the grid and reduce overall power bills. Households looking to maximise these benefits might consider integrating a Best Home Energy Management Systems in Australia 2026: Slash Bills by $1,000+ Annually to intelligently manage their energy use during these free periods.

Why Are Prices Falling?
The AER’s decision reflects a combination of factors, primarily easing cost pressures within the electricity supply chain. Wholesale electricity costs, which typically constitute a significant portion of a customer’s bill, have seen notable decreases.
Data from Q2 2026 (April-June) shows average volume-weighted quarterly wholesale prices ranging from $60 per MWh in Victoria to $95 per MWh in South Australia. New South Wales experienced the largest decrease, falling from $188 per MWh to $78 per MWh compared to the same quarter last year.
This decline is largely attributed to:
- Increased Renewable Generation: More wind and battery generation entering the National Electricity Market (NEM) has reduced reliance on more expensive gas and hydro generation, particularly during evening peaks.
- Lower Electricity Futures Prices: Reduced forward market prices signal expectations of ongoing lower wholesale costs.
- Reduced Spot Market Volatility: Fewer instances of extremely high spot prices contribute to overall lower wholesale costs.
- Falling Environmental Scheme Costs and Easing Retailer Operating Costs: These additional factors have also contributed to the downward pressure on prices.
What This Means for Your Bill
While the DMO provides a safety net for customers on standing offers, it also serves as a crucial reference price for all electricity plans. Retailers must compare their market offers against the DMO, making it easier for consumers to assess value.
It is important to note that the federal Energy Bill Relief Fund, which provided up to $450 in rebates, concluded on December 31, 2025. The DMO 2026-27 changes are separate from these past government rebates. Consumers are encouraged to compare market offers regularly, even with the DMO reductions. Many households and businesses are already on market offers, which may provide better value than standing offers.

Australians are encouraged to review their latest electricity bills, understand the new DMO rates, and consider how the Solar Sharer Offer could benefit their household’s energy consumption. Proactive engagement with energy retailers and exploring new offers remains key to managing energy costs effectively in 2026.
