Australians lured by the promise of three hours of free electricity daily under the new ‘Solar Sharer’ scheme are being warned that hidden charges could significantly inflate their overall power bills. Launched in July 2026 as part of broader Default Market Offer (DMO) reforms, the program aims to extend the benefits of cheap renewable energy to households without rooftop solar. However, fresh analysis published on August 27, 2026, suggests that higher daily supply and peak usage charges could make the offer an expensive trap for many, potentially adding an extra $0.81 per day to fixed costs.
The ‘Solar Sharer’ offer, which became available from July 1, 2026, in DMO regions across Queensland, New South Wales, and South Australia, grants eligible customers three hours of free electricity during the middle of the day. This initiative was championed by Energy Minister Chris Bowen, who stated it was a regulated offer overseen by the Australian Energy Regulator (AER) to prevent price gouging and ensure consumer benefit.
However, consumer advocates are now raising serious concerns. Gavin Gilchrist, a project manager at Inner West Community Energy, highlighted that for customers on the Ausgrid network in Sydney, the daily supply charge on a Solar Sharer plan could be $1.76, nearly double the $0.95 charged on another market offer from the same retailer. Beyond the free period, peak electricity rates on the Solar Sharer scheme were also found to be “almost twice” the rate of comparable plans, at $0.64 per kilowatt hour (kWh) versus $0.33 per kWh.
“What was a really good idea to encourage people to use electricity in the middle of the day, when we have a glut of electricity on the market, has turned into a fiasco that means virtually no one will benefit.” – Gavin Gilchrist, Inner West Community Energy
Energy Consumers Australia echoed these sentiments, noting that the scheme forces consumers into a “complex trade off” between free daytime energy and substantially higher prices during all other periods. This design could leave many households, particularly renters and apartment dwellers who may struggle to shift significant energy use to the middle of the day, worse off financially.
The Mechanics of the Default Market Offer and Solar Sharer
The Default Market Offer, set annually by the AER, acts as a safety net for customers on standing offers and a reference price for comparing market offers. The AER’s final DMO determination for 2026–27, released on May 26, 2026, confirmed price reductions for most residential and small business customers in NSW and South East Queensland, with small businesses in South Australia also seeing falls. Residential customers in South Australia, however, faced a modest increase of 1.4%.
The Solar Sharer Offer (SSO) was specifically introduced as part of these DMO reforms to leverage Australia’s abundant midday solar generation. It mandates that retailers with over 1,000 customers in DMO jurisdictions offer the free electricity period to eligible smart meter households. The government’s intention was to deliver long-lasting bill savings, improve grid stability, and better utilise rooftop solar, even for those without their own panels.
However, the structure of the Solar Sharer, with its higher fixed and peak charges, means that households must meticulously manage their electricity consumption to truly benefit. This requires a significant shift of energy-intensive activities—such as running dishwashers, washing machines, and air conditioning—into the three-hour free window. For many, especially those working outside the home or with inflexible schedules, this behavioural change may be impractical or insufficient to offset the increased costs incurred during other periods.
Comparing Energy Plans is Crucial
The warnings underscore the critical importance of carefully comparing energy plans and understanding all associated charges before switching. While the DMO aims to protect disengaged customers, market offers, when chosen wisely, often provide better value. The difference between standing offers and the best available market offers can be hundreds of dollars annually, with some households overpaying by an average of $380 per year.
For households considering plans with dynamic pricing structures like the Solar Sharer, a thorough analysis of their typical energy consumption patterns is essential. Tools like the government’s Energy Made Easy website allow consumers to compare various offers from major retailers including AGL, Energy Australia, Origin, and Red Energy.

What the Price Differences Look Like
To illustrate the potential impact, here’s a comparison based on the analysis for a typical Ausgrid network customer:
| Charge Type | Standard Market Offer (Example) | Solar Sharer Offer (Example) | Difference |
|---|---|---|---|
| Daily Supply Charge | AUD $0.95 | AUD $1.76 | +AUD $0.81/day |
| Peak Usage Rate | AUD $0.33/kWh | AUD $0.64/kWh | +AUD $0.31/kWh |
This table highlights the substantial increases in both fixed and variable costs that consumers might face if they do not sufficiently capitalise on the free power period. The intent of the Solar Sharer scheme to democratise access to cheap solar energy is laudable, but the implementation appears to place a significant burden on consumers to actively manage their consumption or risk higher bills. Australian households are advised to scrutinise the fine print and compare their specific usage patterns against any new offer before making a switch.
