Understanding Australia’s Solar Sharer Offer: Three Free Daytime Hours for Homes

The federal government is rolling out the Solar Sharer Offer, obligating energy retailers to provide at least three hours of free electricity each day. The scheme launches on 1 July 2026 in New South Wales, South Australia and South‑East Queensland and applies to any household with a smart meter that opts in. It taps into the midday surplus created by more than 4.3 million rooftop solar systems, when wholesale prices often turn negative. By handing that cheap power to consumers, the policy aims to smooth demand and lower overall bills. For developers and builders, the shift reshapes load profiles and influences future energy‑efficiency designs.

What happened

Energy retailers are now required to include a plan that offers at least three free electricity hours per day, timed to the peak solar output window—typically 11 am to 2 pm in NSW and SE Queensland, and 12 pm to 3 pm in SA. Participation hinges on having a smart meter, which most Australian homes already possess; retailers will install one at no charge where needed. The free window is capped at 24 kWh per day, enough for common appliances like washers, dryers, pool pumps, or EV chargers.

The scheme is part of the federal Default Market Offer framework, which currently covers only the three states mentioned. While Victoria, the ACT and other jurisdictions are not yet included, several retailers have already piloted similar voluntary plans, and expansion is expected by 2027. The policy follows a public consultation that refined the original headline of “three hours of free daytime electricity” to include the smart‑meter opt‑in and daily cap.

Why it matters

By redirecting excess solar generation to residential use, the offer helps mitigate negative wholesale prices that can destabilise the grid. Shifting loads to midday reduces evening peak demand, potentially easing pressure on generation capacity and lowering long‑term network costs. Households without rooftop panels—renters and low‑income families—gain direct access to renewable energy savings, addressing equity concerns. However, the benefit is uneven: only customers in the covered states and those with smart meters can participate, and the capped 24 kWh may limit high‑usage scenarios.

How to think about it

If you’re designing a new residential development, factor the free‑hour window into your energy‑efficiency strategy. Install smart meters as standard and provide residents with scheduling tools (e.g., timer‑enabled appliances or home‑energy management systems) that align high‑draw loads with the free period. For existing homes, advise occupants to shift laundry, pool pumps, and EV charging to the midday window to maximize the benefit. Keep an eye on state‑level policy updates, as the offer may expand beyond the current jurisdictions, affecting future market calculations.
