Australian households and small businesses across the National Electricity Market (NEM) are on high alert this week, as the Australian Energy Regulator (AER) and the Essential Services Commission (ESC) prepare to release their final Default Market Offer (DMO) and Victorian Default Offer (VDO) determinations for the 2026-27 financial year. These decisions, due by May 26, 2026, will lock in the maximum electricity prices for standing offer customers from July 1, potentially bringing welcome relief after several years of rising energy costs.
The draft determinations, released earlier this year, indicated significant price reductions driven primarily by lower wholesale electricity costs and a surge in renewable energy generation. However, recent increases in network charges and broader inflationary pressures, flagged by the Reserve Bank of Australia, cast a shadow of uncertainty over whether the full extent of these proposed cuts will materialise in the final figures.
Potential Savings for Households and Businesses
The AER’s draft DMO for New South Wales, South East Queensland, and South Australia, published on March 19, 2026, proposed a decrease in annual prices across all regulated regions. For residential customers, the draft suggested falls between 1.3% and 10.1%, translating to annual savings ranging from approximately $58 to $226. Small businesses stood to benefit even more, with proposed reductions between 7.6% and 21.2%, potentially saving them $379 to $1,320 annually, depending on their distribution zone.
Similarly, in Victoria, the ESC’s draft VDO decision, announced on March 12, 2026, indicated average annual bill reductions. Domestic customers could see savings of around $46 (3%), while small businesses might save $172 (5%) on flat tariff offers, averaged across the state’s five distribution zones.
“This draft decision points to the potential for some welcome relief for households and small businesses after several years of rising energy costs following Russia’s invasion of Ukraine,” said AER Chair Clare Savage in March 2026 regarding the DMO.
These proposed reductions reflect an easing of wholesale electricity costs, where falling contract prices, reduced spot price volatility, and increased output from wind and battery generation have played a significant role. According to AEMO, large-scale batteries are increasingly setting wholesale electricity prices, displacing gas and hydro, and significantly shifting energy from daytime to evening peaks.
Rising Network Charges and Broader Economic Headwinds
Despite the positive outlook from wholesale markets, the Australian Energy Regulator approved electricity distributors’ annual pricing proposals for 2026–27 on April 24, 2026, revealing that network charges are mostly increasing across the Australian Capital Territory, New South Wales, Northern Territory, Queensland, South Australia, and Tasmania. These increases are primarily driven by revenue paths set in regulatory determinations, rising transmission costs, inflation, and the recovery of previously under-recovered revenue. While retailers ultimately determine how these charges are reflected in retail prices, they represent an upward pressure that could mitigate some of the anticipated DMO/VDO reductions.
Further, the Reserve Bank of Australia (RBA) expressed concerns on May 19, 2026, that higher global energy costs, particularly oil prices, could quickly feed into Australian consumer prices, potentially impacting inflation expectations. While directly related to fuel, such broad energy cost pressures can indirectly influence the wider economic environment in which electricity prices are set.
The Solar Sharer Offer and Consumer Action
Accompanying the DMO reforms is the introduction of the Solar Sharer Offer (SSO), which will require retailers to provide households with smart meters in DMO regions at least three hours of free electricity in the middle of the day. This opt-in offer, available from July 1, 2026, aims to help households, including those without solar panels, reduce their bills by shifting energy use to peak solar generation periods, while also supporting grid stability. Customers can access up to 24 kWh of free electricity daily through this scheme.
As the final DMO and VDO decisions are imminent, consumers are encouraged to use this opportunity to review their current electricity plans. The DMO and VDO serve as a safety net and a reference price, but they are not always the cheapest options available. The Australian Energy Council, representing retailers, has consistently reminded consumers that competitive market offers often provide better value.
| Region | Residential (Draft) | Small Business (Draft) | Final Decision Due By |
|---|---|---|---|
| NSW, SE QLD, SA (DMO) | -1.3% to -10.1% | -7.6% to -21.2% | May 26, 2026 |
| Victoria (VDO) | -3% ($46) | -5% ($172) | May 24, 2026 |
This week’s announcements will provide clarity on the exact price changes. Regardless of the outcome, actively comparing and switching electricity providers remains one of the most effective ways for Australians to manage their energy bills.

The introduction of the Solar Sharer Offer also underscores the growing importance of time-of-use tariffs, making it crucial to learn How to Avoid Peak Demand Charges and Slash Your Time-of-Use Electricity Bills in Australia in 2026.
Gas Market Stability
In related news, the Minister for Resources announced on May 15, 2026, that the Australian Domestic Gas Security Mechanism (ADGSM) would not be activated for the third quarter of 2026 (July-September). This decision, based on advice from the ACCC and AEMO, indicates that sufficient domestic gas supply is expected on the east coast, supported by full storage facilities, adequate pipeline infrastructure, and a forecast warmer-than-average winter.
Separately, the Federal Government confirmed in its May 12, 2026 Budget a new mandatory domestic gas reservation scheme, to be legislated and commence on July 1, 2027. This scheme will require LNG exporters to reserve 20% of their total export production for the domestic market, aiming to ensure secure and affordable gas supply in the long term.
While the immediate outlook for gas supply appears stable, the focus remains on electricity prices this week as the final DMO and VDO figures are set to be unveiled, directly impacting millions of Australian energy consumers from July 1, 2026.
