Many Australian households expected relief on their electricity bills this July, following the Australian Energy Regulator’s (AER) final Default Market Offer (DMO) and the Victorian Essential Services Commission’s (ESC) Victorian Default Offer (VDO) determinations. These regulatory decisions, effective from 1 July 2026, indeed brought price reductions for most customers on standing offers across New South Wales, South East Queensland, and Victoria. However, for a significant number of consumers, these anticipated savings are being offset, or even reversed, by a notable increase in daily supply charges from major retailers.

This shift in billing structure, coupled with the introduction of a new ‘Solar Sharer Offer’ and recent warnings from the Australian Competition and Consumer Commission (ACCC) regarding consumer energy resources, paints a complex picture for household energy costs this winter.

Default Market Offer Delivers Mixed Fortunes

The AER’s final DMO determination, released on 26 May 2026, confirmed that residential flat-rate standing offer prices would fall between 3.4% and 5.0% in New South Wales, translating to annual savings of approximately $66 to $137. South East Queensland households on similar plans are set to receive a 7.2% price decrease, saving around $155 annually. In Victoria, the VDO announced on 24 May 2026, means average household bills will decrease by 5%, delivering an annual saving of $84.

These reductions were largely driven by easing wholesale energy costs, increased renewable energy generation, and expanded battery storage capacity in the National Electricity Market (NEM).

However, not all regions saw cuts. Residential flat-rate standing offer customers in South Australia faced a modest increase of 1.4%, equating to an annual rise of approximately $33.

Small businesses generally fared better, with reductions across all three DMO regions. Prices decreased between 9.0% and 20.9% in New South Wales, 10.4% and 14.0% in South East Queensland, and 6.8% and 12.1% in South Australia, depending on the tariff structure.

The Rising Cost of Staying Connected: Retailer Tactics Under Scrutiny

Despite the DMO and VDO setting lower benchmark prices, many Australians on market offers are reporting increased overall bills since July 1. This unexpected outcome is largely due to energy retailers, including major players like AGL, Origin, and EnergyAustralia, significantly increasing their fixed daily supply charges.

This strategy effectively shifts a greater portion of the bill from usage-based charges (cents per kilowatt-hour) to a flat daily fee, regardless of how much electricity is consumed. For households with low energy usage, or those with rooftop solar panels who are highly self-sufficient, this change means their fixed costs rise, diminishing or even eliminating any savings from lower usage rates. The Australian Energy Council noted that the AER, in its 2026-27 determination, explicitly defined tariff structures, leading to a greater emphasis on fixed daily supply charges.

“We’ve seen some companies – not all, far from it – choose to increase their fixed supply costs while reducing their per-kilowatt hour costs,” Energy Minister Chris Bowen stated, confirming an investigation has been requested from the AER and ACCC.

This structural change in billing, while permitted, has led to consumer confusion and frustration, as the headline price cuts do not always translate to lower overall bills. Consumers are urged to actively compare offers and understand the breakdown of fixed and variable charges.

The New Solar Sharer Offer: Free Power, With Conditions

Another significant change effective from 1 July 2026 is the introduction of the Solar Sharer Offer. This new opt-in default plan requires retailers in DMO regions (New South Wales, South Australia, and South East Queensland) to offer eligible smart meter households three hours of free electricity daily, capped at 24 kWh.

The free usage window is typically 11:00 AM to 2:00 PM in NSW and SE QLD, and 12:00 PM to 3:00 PM in SA, designed to encourage consumption during periods of high solar generation. Crucially, you do not need to have solar panels installed to access this offer, only a smart meter.

While seemingly a boon for consumers, analysis shows that Solar Sharer plans often come with higher daily supply charges and higher peak rates outside the free window. To truly benefit, households must be able to significantly shift their electricity usage into the designated free period. Experts suggest that those with home battery systems or electric vehicles (EVs) are best positioned to maximise savings by charging during the free window. Victoria is expected to introduce a similar “Midday Power Saver” initiative from 1 October 2026.

Consumer Protections and the Rise of Smart Energy Systems

Beyond price adjustments, new consumer protections also took effect on 1 July 2026. Retailers are now limited to one price increase per year, account establishment and re-energisation fees are eliminated, and at least one free payment method must be offered.

Meanwhile, the ACCC’s 15th Electricity Market Inquiry report, published on 10 July 2026, highlighted the increasing role of home batteries and Virtual Power Plants (VPPs) in delivering significant bill savings. The report found that households with solar and battery systems recorded annual electricity bills between $329 and $909 (20-52%) lower than grid-only customers. Participation in VPPs further amplified these savings, with median annual bills $762 to $1,093 (57-63%) lower.

However, the ACCC also raised concerns about a 107% increase in consumer complaints over the past 12 months regarding consumer energy resources. Issues included unsuitable systems, faulty installations, poor battery performance, and difficulties in resolving problems. The report called for stronger consumer protections, including a mandatory code of conduct for battery sellers and installers, and expanding energy ombudsman scheme coverage to address disputes.

Consumers considering home battery systems or VPP participation should research thoroughly and understand contract terms.

In this evolving energy landscape, active engagement with energy plans and an understanding of billing structures remain crucial for Australian households to manage their costs effectively.
