Australia Solar Sharer Offer: Free Daytime Electricity for Households

The Solar Sharer Offer provides free midday electricity to stabilize the grid

From July 1, 2026, energy retailers in New South Wales, South Australia, and South-East Queensland must offer residential customers at least one energy plan that includes three hours of free daytime electricity. This initiative, known as the Solar Sharer Offer, aims to shift household energy consumption to midday periods when rooftop solar generation is so high that wholesale electricity prices often turn negative.

To qualify for these free windows, households must have a smart meter and opt into a qualifying plan through their retailer. The scheme is designed to be inclusive, meaning renters and apartment dwellers can benefit without needing to own a home or install their own solar panels.

Key Implementation Details and Limitations

Geographic Availability

While the initial launch on July 1, 2026, covers NSW, South Australia, and South-East Queensland (states under the federal Default Market Offer framework), other regions are expected to follow:

• Victoria: Currently under consultation, with a potential expansion in October 2026.
• Other States: Expected to follow by 2027.

The 24 kWh Daily Usage Cap

Following public consultation in late 2025, the government introduced a "reasonable use" cap of 24 kWh per day for the free electricity window. This cap is intended to ensure the financial sustainability of the scheme for retailers.

For a typical five-person household, 24 kWh roughly covers total daily electricity use. Most households are unlikely to hit this cap during a three-hour window unless they are simultaneously charging a large home battery and an electric vehicle (EV) from the grid.

Estimated Annual Savings

According to the Department of Climate Change, Energy, the Environment and Water (DCCEEW), savings depend on the percentage of total energy use shifted into the free window:

• 10% shift (one major appliance): $100 to $190 per year.
• 20% shift (dryer or hot water): $300 to $790 per year.
• 25-30% shift (pool pump, EV, dishwasher): $400 to $1,100 per year.

Strategic Use for Solar and Battery Owners

For households already equipped with solar and batteries, the Solar Sharer Offer acts as a supplement rather than a replacement. The free window allows users to "top up" home batteries from the grid at no cost during overcast days or winter months, ensuring they have stored energy for the expensive evening peak periods.

EV owners can significantly reduce costs by scheduling vehicle charging to coincide with the free midday window rather than charging overnight.

Critical Analysis and Consumer Trade-offs

While the headline of "free electricity" is attractive, community discussion and technical analysis highlight several important caveats:

Plan Cost Trade-offs

Industry observers note that that these plans are rarely "free" in the absolute sense. Retailers may recoup the cost of the solar sharer plans by increasing daily supply charges or raising usage rates for electricity consumed outside the free period.

"The downside of these solar sharer plans... is that they generally have higher daily supply charges and higher usage charges outside the ‘free’ window to recoup the costs of the ‘free’ electricity."

Infrastructure and Automation Requirements

To realize maximum savings, households need the ability to shift load. This requires either being home during the day or possessing smart appliances (programmable dishwashers, EV chargers, or heat pump hot water systems) that can automate the shift.

Grid Impact

Some users have reported that the rapid adoption of voluntary versions of these plans has already caused noticeable dips in grid frequency around 11:00 AM as thousands of batteries and appliances trigger simultaneously.
