Three hours of free electricity every day sounds like a straightforward way to cut household bills. But Australia’s Solar Sharer Offer can be cheaper or more expensive than an ordinary electricity plan, depending on when your household uses power. Available since 1 July 2026, the regulated opt-in offer gives eligible smart-meter households in New South Wales, South Australia and south-east Queensland a daily free-usage window of up to 24 kilowatt-hours (kWh). You don’t need rooftop solar, and renters can qualify. The catch: daily supply charges and potentially higher time-of-use rates outside those hours still apply.

What is the Solar Sharer Offer — and when does the free electricity start?
The Solar Sharer Offer (SSO) is a regulated standing offer under Australia’s Default Market Offer framework. Participating retailers must make it available to eligible residential customers, but customers have to opt in; they are not automatically switched over. Retailers with more than 1,000 customers across the DMO regions are generally required to offer it. Smaller retailers can be exempt. Source: Energy Made Easy consumer guide.
| Eligible region | Daily free-power window |
|---|---|
| New South Wales | 11am–2pm local time |
| South-east Queensland | 11am–2pm AEST |
| South Australia | 12pm–3pm local time |
Those local clock-time windows apply every day, including weekends, and stay at the same local times through the year. The NSW and SA clock times continue to follow local daylight-saving arrangements where applicable; Queensland does not observe daylight saving.
Who is eligible? Five things to check
- Your address: you must be a residential customer in a NSW, South Australian or south-east Queensland Default Market Offer area.
- Smart meter: you need an electricity meter capable of recording usage by time interval. If your property lacks one, ask the retailer about installation, timing, access requirements and any fee.
- Supply arrangement: customers whose electricity is supplied through an embedded network, common at some apartments, caravan parks or retirement villages, are not eligible under the ordinary SSO rules.
- Retailer: the retailer must offer the regulated SSO; eligible customers can compare their retailer’s offering with others.
- Home ownership: both owners and renters can qualify, and neither needs rooftop solar panels.
You can ask your retailer whether you already have a smart meter, whether your supply is embedded and whether an opt-in change affects your current discounts or billing arrangement. Government eligibility and enrolment steps.
Is the electricity really free, and what is the 24 kWh limit?
Yes, the usage charge for the first 24 kWh of eligible electricity imported during the three-hour window is $0. The 24 kWh threshold applies each day, not as a monthly bank of credits. Electricity above that cap during the window is charged at a regulated reasonable-use rate, generally linked to the applicable off-peak or solar-soak rate. Energy Made Easy explains the fair-use cap.
A free usage rate is not the same as a free electricity account. You still pay the daily supply charge, electricity consumed outside the window and other applicable charges. Importantly, appliances on a separately metered controlled-load circuit — often certain hot-water systems — are billed at their own controlled-load tariff, so those units do not automatically become free at midday.
The real comparison: when an ordinary electricity plan costs less
Many competitive market plans have a lower supply charge or lower evening and off-peak tariffs than a regulated standing offer. Solar Sharer may charge more for usage outside its free window. A household that runs cooking, cooling and other appliances mainly after work could lose more on those charges than it saves at lunchtime. Conversely, someone who can regularly schedule large loads during the free period may come out ahead.
Consider a deliberately simplified example. A standard flat-rate plan costs $1.20 per day plus 30 cents per kWh. A hypothetical Solar Sharer plan costs $1.70 per day plus an average of 44 cents per kWh outside the free window; its first 24 kWh during the window costs nothing. Both assume 12 kWh total daily consumption, no controlled-load charges and constant rates over 365 days. These are fictional rates, not quotes from any retailer or the Australian Energy Regulator. In real life, Solar Sharer’s paid rate varies by time of day, so this blended-rate model is only for showing the trade-off.
Under those assumptions the standard plan costs $4.80 a day, or $1,752 a year. This is how the Solar Sharer alternative changes as more of the same 12 kWh is consumed in the free window:
| Used in free window | Solar Sharer per day | Annual difference vs standard |
|---|---|---|
| 2 kWh | $6.10 | Cost $475 more |
| 6 kWh | $4.34 | Save $168 |
| 9 kWh | $3.02 | Save $650 |
The break-even point in this illustration is about 5 kWh during the free window each day. A household that can only shift 2 kWh would pay substantially more; one able to use 9 kWh then would save. The number is not universal and cannot be transferred to another retailer’s rates, controlled loads or household profile.
What is the best way to estimate your actual savings?
Use Energy Made Easy, the Australian Energy Regulator’s government-backed plan comparison service. Start with your postcode or, where available, enter the National Metering Identifier (NMI) printed on your electricity bill to incorporate up to 12 months of actual usage data into an estimate. Quick Compare uses typical household usage assumptions and may be much less reliable for a household with highly unusual hours.
Compare the total estimated annual cost, not just the three-hour zero-cent rate. Check the daily supply charge, each peak and off-peak or shoulder price, any controlled-load tariff, solar feed-in tariff, sign-up credit expiry, green-energy add-ons and any fees. Make sure the comparison reflects how much electricity you can realistically move into the free period, including weekdays when nobody is home.
Which households could benefit most?
- People home during the day: retirees, people working from home or households with daytime cooling and heating needs may be able to use more of the free energy.
- EV owners: electric vehicles with safely configured, controllable daytime charging may shift a meaningful amount of consumption into the window, subject to the 24 kWh daily cap and charger power.
- Households with timers: dishwashers, washing machines, dryers and compatible appliances can be scheduled when safe and practical, avoiding unnecessary peak-period electricity.
- Home batteries: some customers may charge a suitable system in the free window for use later, but losses, controls, warranty requirements and any equipment costs affect the economics.
The best savings often come from shifting electricity you would have used anyway, rather than switching on extra appliances merely because a tariff happens to be free. Think in kWh rather than simply counting the number of devices turned on.
Who might be better off staying on a conventional plan?
Solar Sharer may be less appealing to people who are away during the day and cannot automate much consumption; those with large evening loads; customers already enjoying a sharply discounted market tariff; and households whose hot-water electricity is separately controlled and therefore excluded from the free usage period.
Homes with rooftop solar need special care too. Rooftop panels may already supply much of the home’s midday demand without drawing electricity from the grid. The zero-cent SSO rate generally applies to eligible grid imports, not to electricity the solar system already produces and consumes on site. Compare any change to your feed-in credit, time-of-use rates and battery strategy before switching.
What about Victoria and the other states?
The federal Solar Sharer Offer described here covers NSW, SA and south-east Queensland. Victoria has its own separate Midday Power Saver, introduced on 1 October 2026, with a daily 11am–2pm no-cost window and its own plan rules. Victorians should compare offers through Victorian Energy Compare. Do not assume the federal SSO eligibility rules or tariffs apply nationwide.
A six-step checklist before you opt in
- Check the exact retailer’s Solar Sharer plan and that your home has an eligible smart meter.
- Download the current bill and identify daily supply charges, peak charges, NMI and any controlled load.
- Estimate how many kWh you can reliably use or shift into the daily three-hour window.
- Compare a full year’s projected cost with at least one competitive flat-rate or time-of-use plan.
- Ask what will happen to existing concessions, solar feed-in credits, discounts and contract terms.
- After switching, inspect the next bills and your usage by time of day; reassess if savings fail to appear.
The regulator stresses that an SSO is optional. A consumer-protection rule requiring major retailers to offer it does not mean it will be the cheapest product for every customer. The ACCC’s 2026 enforcement update also highlights why retailer compliance and clear disclosure are important.
Electricity bills are only one part of the pressure on household budgets. For broader context, see our NextNews report on Australian household spending and rising costs.
The verdict: is the Solar Sharer Offer worth it?
Potentially yes — but only after comparing the whole bill. The opportunity is real for customers who can consistently shift enough electricity use into midday. It can be especially attractive for controlled EV charging, flexible daytime heating and cooling, or appliances with safe scheduling options. Yet a low-priced market offer can win for households facing expensive evening usage or higher fixed charges under Solar Sharer.
If you cannot estimate your likely free-window usage, start by asking your retailer for an interval-usage breakdown and compare total annual costs before opting in. What matters is the bottom line, not the free-power headline.
