The Australian Energy Regulator (AER) regularly updates the pricing frameworks that shape household and small business power bills across the country. If you live in New South Wales, South Australia, or South East Queensland, the Default Market Offer (DMO) directly influences how much you pay for electricity. The AER sets this benchmark to act as a fair safety net for consumers who remain on standing offer contracts, protecting them from excessive retail charges. Driven by falling wholesale electricity costs and increased output from renewable generation, the 2026-27 updates propose welcome price reductions across most regions. Navigating these changes allows households to make informed decisions about their energy contracts, shift their usage habits, and deploy home battery storage to mitigate the impact of expensive evening rates.
Key Takeaways
- The AER proposes residential electricity price reductions ranging from 1.3% to 10.1% across regulated regions for the 2026-27 period.
- Small business customers see even steeper proposed price drops, ranging from 7.6% up to 21.2% depending on the distribution zone.
- The update introduces the Solar Sharer Offer, providing eligible households with three hours of free midday electricity to encourage daytime power consumption and stabilise the grid.
- The DMO serves as a standard reference price, making it easier for consumers to compare competitive market plans from various retailers.
- Households can capture free midday grid power or excess solar energy in a home battery system, deploying it during peak evening periods to reduce overall electricity costs.
Understanding What DMO Electricity Is and How It Works
The Safety Net Cap
To understand what DMO electricity is, you must look at standing offers. Energy retailers automatically place customers on standing offers if they do not actively select a competitive market plan, such as when they move into a new property or let a previous contract expire. The AER sets the DMO as a strict price ceiling, meaning energy retailers cannot charge standing offer customers more than this specified annual limit. The DMO also functions as a universal reference price, requiring all retailers to compare their market offers against this baseline so consumers can easily identify better deals.
Targeted Regions
The DMO applies specifically to residential and small business customers in New South Wales, South East Queensland, and South Australia. Other Australian regions operate under their own distinct regulatory frameworks. For example, Victoria relies on a separate pricing benchmark known as the Victorian Default Offer (VDO), which is set by the Essential Services Commission.
Cost Components
The AER calculates the DMO by assessing the efficient costs required to supply electricity to a standard household or small business. According to the AER's 2026-27 draft determination, the underlying costs that dictate your electricity bill consist of four primary components:
| Cost Component | Description | Percentage of DMO Bill (2026-27) |
| Network Charges | The cost to transport electricity through local poles, wires, and substations. | 39% – 48% |
| Wholesale Costs | The cost for retailers to buy electricity on the spot and contract markets. | 32% – 44% |
| Retail Costs & Margin | The cost to serve customers, manage billing, and maintain a reasonable profit margin. | 7% – 16% |
| Environmental Schemes | The cost to comply with government renewable energy and environmental policies. | 2% – 3% |
Pro-Tip: Network charges and wholesale costs make up the vast majority of your electricity bill. While portable power stations like the BLUETTI Elite 200 V2 (featuring a 2,073.6Wh capacity) cannot hardwire directly into your home's main circuit board to run the entire house, they are highly effective for targeted load shifting. By charging the unit from your wall outlets during off-peak hours or free midday electricity periods, you can run heavy-draw plug-in appliances directly from the battery during the expensive evening peak, bypassing these high wholesale and network charges entirely.
Key Changes to the 2026 Default Market Offer
According to the Australian Energy Regulator (AER) draft determination, the 2026 updates introduce significant structural and pricing shifts designed to lower consumer costs.
Regional Price Reductions
The draft determination for the 2026 regulated electricity price highlights notable drops driven by lower wholesale energy contract prices and reduced environmental compliance costs.
| Distribution Network (State) | Proposed Residential Price Reduction | Estimated Annual Saving |
| Ausgrid / Endeavour / Essential (NSW) | 2.4% to 8.2% | $58 to $226 |
| Energex (South East Queensland) | 10.1% | $216 |
| SA Power Networks (South Australia) | 1.3% | $31 |

The Solar Sharer Offer (SSO)
The 2026 framework introduces the Solar Sharer Offer, an opt-in tariff requiring retailers to grant eligible households three hours of free electricity during peak solar generation times. This free usage period runs from 11:00 am to 2:00 pm in New South Wales and South East Queensland, and 12:00 pm to 3:00 pm in South Australia.
New Tariff Caps
To improve pricing transparency, the AER now imposes specific capped rates on both daily supply charges and usage charges. This regulatory move prevents energy providers from burying excessively high peak rates within standing offer plans that feature a low overall annual cost.
Time-of-Use Benchmarks
For the first time, the DMO structure includes a distinct annual reference price for time-of-use (TOU) tariffs. This addition simplifies the comparison process for homes utilising smart metres, clearly displaying the varying costs associated with peak, shoulder, and off-peak consumption.
How the Reference Price Helps You Compare Energy Plans
A Standardized Benchmark
Energy retailers must use the DMO as the universal reference price when advertising their competitive market offers. This legal requirement forces providers to compare their plans against the exact same base rate, offering you a clear baseline for evaluating different retail contracts.
Decoding Advertised Discounts
The reference price eliminates the confusion of complex percentage discounts. When a retailer advertises a plan as "15% below the reference price", you immediately know it offers better value than a competing plan advertised as "10% below the reference price".
Market Offers vs. Standing Offers
The DMO acts as a pricing safety net, not the cheapest available deal. Competitive market offers routinely sit well below the regulated DMO benchmark. According to the AER, the lowest market offers are typically 18% to 27% cheaper than the DMO baseline. Consumers who actively switch away from standing offers secure much lower rates.
Maximising the 2026 DMO Updates with Battery Storage
Strategic Load Shifting
The introduction of the Solar Sharer Offer creates a prime financial opportunity for battery owners. Households can draw free grid electricity during the three-hour midday window to charge their battery systems. They then power their homes directly from the battery during the costly evening peak, bypassing high time-of-use rates completely.
Pro-Tip: You do not need a massive rooftop solar array to benefit from midday grid power. By programming your portable power station or home battery to charge exclusively during the Solar Sharer Offer window, you capture free energy to deploy when peak rates hit after 4:00 pm.

Designed to deliver essential home backup, the BLUETTI Elite 300 offers a 3,014Wh capacity and a 2,400W output. Users can charge the unit using portable solar panels or midday grid power. Once charged, the Elite 300 acts as a clean alternative to traditional generators, keeping critical appliances running reliably through the expensive evening peak or during unexpected outages.
Product Solution: BLUETTI EP760 & EP2000
For comprehensive property integration, the BLUETTI EP760 and EP2000 provide highly capable home energy storage solutions. The EP760 single-phase system and the robust EP2000 three-phase system scale seamlessly to meet your exact power demands. These systems allow homeowners to capture maximum solar generation or free grid power, actively targeting energy independence and sustaining the home through peak billing hours.
Understanding the Limitations
While battery storage drastically reduces daily energy costs, these systems require a considerable upfront financial investment. The speed of your financial return depends heavily on your household securing a compatible time-of-use tariff and actively consuming your stored power during peak evening hours. Simply exporting stored energy back to the grid yields minimal returns due to continuously falling feed-in tariffs.
Taking Charge of Your Electricity Costs This Year
Failing to engage with the energy market often means defaulting to a standing offer, which leaves you paying the maximum allowable rate set by the regulator. Start by reviewing your current electricity bill and comparing your plan against the new DMO reference price to identify immediate savings opportunities.
Once you secure a competitive market offer, incorporating a home battery system like the BLUETTI Elite 300 or the BLUETTI EP760 allows you to physically reduce your reliance on the grid. By capturing free midday power through the Solar Sharer Offer and deploying it during the evening, you take full advantage of the 2026 tariff structures and shield your household from volatile peak energy costs.
To help you understand how these systems sustain your appliances during peak billing hours, here is a breakdown of expected performance based on battery capacity:
| BLUETTI System | Battery Capacity | Output Power | Estimated Runtime (Running a 500W Heater/Fridge) |
| Elite 300 | 3,014Wh | 2,400W | ~5.1 hours |
| EP760 (with 2x B500) | 9,920Wh | 7,600W | ~16.8 hours |
Pro-Tip: When planning your evening load shifting, you can estimate how long your battery will power specific devices using this standard formula: Runtime = (Capacity * 0.85) / Wattage. The 0.85 multiplier accounts for the 15% energy loss that naturally occurs during the inverter's DC to AC conversion process.
Frequently Asked Questions
What is DMO electricity, and who sets it?
The Default Market Offer (DMO) is a regulated maximum price cap applied to residential and small business standing offer contracts. The Australian Energy Regulator (AER) sets this benchmark annually to protect disengaged consumers from unfairly high power prices and to establish a universal baseline for the energy market.
How does the Default Market Offer 2026 affect me?
If you live in New South Wales, South Australia, or South East Queensland, the 2026 DMO updates lower the maximum price retailers can charge on standing offers. It also introduces new structures like the Solar Sharer Offer, providing three hours of free midday power, which you can use to run heavy appliances or charge a home battery system for evening use.
What is the reference price in Australia?
The reference price is a standardised benchmark based directly on the DMO. Energy retailers must use this exact figure when advertising their competitive market plans, allowing you to easily compare different electricity offers and accurately determine which plan provides the highest percentage discount.
Does the regulated electricity price in 2026 mean my bills will automatically drop?
Not necessarily. While the DMO safety net is dropping for most regions, the vast majority of households sit on competitive market offers, not standing offers. To see actual savings, you must actively compare your current retail plan against the new reference price and switch to a more competitive deal.
