Australian households and small businesses across New South Wales, South East Queensland, and South Australia are set to experience significant changes to their electricity bills from July 1, 2026, following the Australian Energy Regulator’s (AER) final Default Market Offer (DMO) determination for the 2026-27 financial year. Most customers on standing offers will see price reductions, with some residential customers potentially saving up to $229 annually, alongside the introduction of a new Solar Sharer Offer (SSO) providing three hours of free electricity daily for smart meter homes.
The AER’s final decision, released on May 26, 2026, acts as a regulated safety net for customers on standing offer contracts and serves as a reference price for comparing market offers. The determination reflects easing cost pressures within the electricity supply chain, particularly due to the increasing penetration of renewable energy and grid-scale batteries.
“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,” stated AER Chair Clare Savage. “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.”
Residential Bill Impacts from July 1, 2026
For residential customers on flat rate standing offers, the changes vary by state:
| Region | Change from July 1, 2026 | Annual Saving/Increase (AUD) |
|---|---|---|
| New South Wales | -3.4% to -5.0% | -$66 to -$137 |
| South East Queensland | -7.2% | -$155 |
| South Australia | +1.4% | +$33 |
Households with smart meters on time-of-use (TOU) standing offers will generally see greater savings:
| Region | Change from July 1, 2026 | Annual Saving/Increase (AUD) |
|---|---|---|
| New South Wales | -3.7% to -7.7% | -$72 to -$211 |
| South East Queensland | -10.7% | -$229 |
| South Australia | -1.1% | -$25 |
While most regions benefit from reductions, South Australian residential customers on flat rate offers will experience a modest 1.4% increase, equating to an extra $33 annually. However, those with smart meters in SA will see a slight decrease.
Small Businesses See Significant Relief
Small businesses are set to receive even more substantial reductions across all three DMO regions. Depending on their tariff type, prices will decrease by:
- New South Wales: -9.0% to -20.9%, saving businesses up to $1,303 annually.
- South East Queensland: -10.4% to -14.0%, saving businesses up to $601 annually.
- South Australia: -6.8% to -12.1%, saving businesses up to $673 annually.
These figures highlight the AER’s focus on alleviating pressure on commercial entities amidst ongoing energy market shifts.
Introducing the Solar Sharer Offer: Free Midday Power
A pivotal component of the new DMO is the mandatory introduction of the Solar Sharer Offer (SSO), effective July 1, 2026. This opt-in plan requires energy retailers with over 1,000 customers to provide eligible households with smart meters three hours of free electricity in the middle of the day.
“The new Solar Sharer Offer is an opportunity to make further savings if households can shift some of their electricity usage, such as washing machines, air conditioning, and EV charging, to these free periods.”
Crucially, the SSO is available to households both with and without rooftop solar panels. This initiative aims to encourage consumers to shift their energy consumption to periods of high solar generation, thereby absorbing excess renewable energy, reducing grid pressure, and ultimately lowering wholesale costs. The free power windows are set as:
- New South Wales & South East Queensland: 11:00 AM – 2:00 PM
- South Australia: 12:00 PM – 3:00 PM
Households can access up to 24 kWh of free electricity during this daily window. This offers a tangible way for smart meter owners to significantly reduce their bills by strategically running appliances like dishwashers, washing machines, or even charging electric vehicles during these times.

Broader Market Context and Retailer Responses
The AER’s determination for DMO regions (NSW, SE QLD, SA) comes as Victoria’s Essential Services Commission (ESC) also announced a separate 5% average reduction for households on the Victorian Default Offer (VDO), saving approximately $84 annually.
These price adjustments are largely driven by a record influx of renewable energy and battery storage into the National Electricity Market (NEM), which has reduced wholesale price volatility. As AER Chair Clare Savage noted, “Batteries have been displacing more expensive gas and hydro in the evenings, and we’ve just seen flatter prices through the whole day. That’s really translated to lower forward electricity contract prices.”
However, some retailers are adjusting their pricing structures in response to the DMO changes. For example, Origin Energy has notified some customers of increases to their daily supply charges, even as usage charges decrease. While Origin expects overall bills to be lower for most customers, this shift means high-consumption households may benefit more, while low-consumption households could see smaller savings or even slight increases depending on their usage patterns and solar PV ownership.
Looking ahead, the Australian Energy Market Commission (AEMC) has flagged a potential “radical overhaul” of electricity pricing, aiming to simplify energy plans for consumers, making them as straightforward as “buying milk.” This proposed change, discussed at Australian Energy Week in June 2026, would shift the complexity of demand charges, export charges, and time-of-use windows onto retailers, potentially saving households $40 to $80 annually by 2040. However, this is a long-term proposal, distinct from the immediate DMO and SSO changes taking effect from July 1.
