From 1 July 2026, Australian households in New South Wales, South Australia, and South East Queensland can access a new regulated electricity plan offering three hours of free electricity every day through the ‘Solar Sharer Offer’. This initiative, designed to leverage Australia’s abundant mid-day solar generation, allows eligible homes to use up to 24 kilowatt-hours (kWh) of power free of charge during a specific daily window. While not entirely “free” in all aspects, strategic use of this offer, combined with a smart meter, can significantly reduce your annual electricity bills by hundreds of dollars, potentially saving a South Australian VPP customer with model usage up to $608 annually in the 2026-27 financial year.
This guide will unpack the Solar Sharer Offer, the essential role of smart meters, and how advanced energy programs like Virtual Power Plants (VPPs) and community batteries can further maximise your savings and contribute to a more stable, renewable-powered grid.
What is the Solar Sharer Offer (SSO)?
The Solar Sharer Offer (SSO) is a new government-regulated electricity standing offer introduced on 1 July 2026. Its primary goal is to encourage Australians to shift their electricity consumption to the middle of the day, when solar energy generation is at its peak and often in surplus, easing pressure on the grid and making better use of renewable resources.
Key details of the SSO:
- Free Period: Three consecutive hours daily. In NSW and South East Queensland, this is typically 11:00 am to 2:00 pm. In South Australia, it’s 12:00 pm to 3:00 pm. Victoria will launch a similar scheme, the ‘Midday Power Saver’, on 1 October 2026.
- Free Usage Cap: The first 24 kWh of electricity used during this three-hour window is free of usage charges. This is roughly the amount of electricity an average five-person household uses over an entire day.
- Excess Usage: If you exceed 24 kWh during the free period, additional electricity is charged at a specified ‘reasonable-use rate’, which must be the cheapest usage rate applied at another time of day under that plan.
- Eligibility: You must live in a Default Market Offer (DMO) area (NSW, SA, or SE Queensland), have a smart meter installed, and be with a retailer offering the SSO. Renters and homeowners are eligible, but those on embedded networks are not. You do not need rooftop solar to participate.
The Australian Energy Regulator (AER) determines the specific free-power period, daily supply charge, and usage rates outside the free window.
The Catch: While the promise of free power is appealing, retailers may offset this benefit with higher electricity rates outside the free window and/or increased daily supply charges. Therefore, the SSO is only truly beneficial if you can actively shift a significant portion of your energy consumption into the designated free period.
The Critical Role of Smart Meters
A smart meter is not just a digital electricity meter; it’s your gateway to modern energy management and participation in offers like the Solar Sharer. These advanced meters record your electricity consumption in granular intervals (e.g., every 5 minutes) and send this data directly to your energy retailer, eliminating estimated bills.
How smart meters unlock savings:
- Eligibility for SSO: A smart meter is a mandatory requirement to access the Solar Sharer Offer.
- Time-of-Use (ToU) Tariffs: Smart meters enable access to ToU tariffs, which charge different rates based on the time of day. This allows you to capitalise on cheaper off-peak rates and the free SSO window.
- Real-time Monitoring: Many smart meters, especially when paired with in-home displays or retailer apps, provide real-time data on your energy usage. This visibility is crucial for identifying high-consumption periods and effectively shifting appliance use.
- Integration with Smart Home Devices: For maximum benefit, smart meters integrate with smart home devices (like smart thermostats or appliance timers) that can automatically schedule high-drain activities during the free period.
While a national mandatory rollout of new smart meters with real-time data capacity is scheduled from 30 November 2028 (Victoria already has them widely installed), if you don’t currently have one and wish to join the SSO, your retailer will typically arrange for its installation.
Beyond Free Power: Virtual Power Plants & Community Batteries
While the Solar Sharer Offer focuses on shifting demand, Virtual Power Plants (VPPs) and community batteries take the concept of shared energy a step further, offering even greater financial benefits and grid stability.
Virtual Power Plants (VPPs)
A VPP is a network of connected home solar and battery systems (and sometimes other distributed energy resources like EVs) that are coordinated by an energy retailer or operator to act like a single, large-scale power station. When the grid is under stress, such as during peak evening demand or when wholesale electricity prices spike, the VPP operator can remotely draw a small amount of stored energy from participating batteries and feed it into the grid.
Benefits of joining a VPP:
- Accelerated Battery Payback: VPP participation can significantly reduce your home battery’s payback period from a typical 7-9 years down to 5-6 years.
- Financial Rewards: Homeowners are compensated through sign-up bonuses, higher feed-in tariffs during VPP events, or direct bill credits. Annual earnings can range from $100 to over $1,000, depending on the provider, battery size, and state.
- Grid Support: By dispatching stored renewable energy, VPPs help stabilise the National Electricity Market (NEM), reduce reliance on fossil fuels, and manage demand peaks, contributing to overall grid security and the renewable energy transition.
- Automated Optimisation: Most VPPs use AI to automatically manage your battery’s charging and discharging based on market conditions, ensuring you earn credits without manual intervention.
Many major battery manufacturers, including Tesla, BYD, and Sungrow, permit VPP participation under their standard warranties.
Community Batteries
Community batteries offer shared energy storage for households, particularly benefiting those who cannot install rooftop solar (e.g., renters or apartment dwellers). These larger batteries store excess local solar energy during the day and discharge it during peak times, lowering electricity bills, supporting grid stability, and reducing emissions for connected homes.
The Australian Government’s Community Batteries for Household Solar program is funding the installation of 400 community batteries across Australia, with significant investments from ARENA and the Business Grants Hub. Western Power, for example, is rolling out 18 new community batteries in Perth and Bunbury, with a combined 6.6 MW of storage capacity, expected online by mid-2027.

State-by-State Incentives & Programs
Beyond the federal rebates, some states offer additional incentives for home batteries, especially when connected to a VPP:
- South Australia: The Retailer Energy Productivity Scheme (REPS) VPP incentive offers up to $2,050 off your battery when connecting to an approved VPP. For the remainder of 2026, this rebate is primarily available to priority group applicants (e.g., pensioners, healthcare card holders). This stacks with the federal rebate, potentially offering combined savings of up to $4,570 for larger systems, though typical 10-13.5kWh systems land closer to $3,100-$3,500 total.
- New South Wales: The Peak Demand Reduction Scheme (PDRS) provides upfront financial incentives for installing a battery (BESS1) and connecting it to an approved VPP (BESS2). This can mean an additional $550 (single unit) to $1,500 (dual unit) reduction for high-consumption households.
- Western Australia: While not directly a VPP rebate, trials like the RENeW Nexus Plan in Fremantle (a partnership with Synergy, Western Power, Curtin University, and Power Ledger) explore peer-to-peer energy trading using blockchain technology, allowing residents to set their own rates for selling excess solar.
Navigating the Grid: Stability & Renewables
The Australian electricity grid, particularly the National Electricity Market (NEM), is undergoing a rapid transformation. The Australian Energy Market Operator (AEMO) forecasts grid-scale wind and solar capacity to more than triple by 2035.
Renewable Energy Zones (REZs) are central to this transition, designated areas with high-quality renewable resources where generation, storage, and transmission infrastructure are strategically developed. AEMO’s Draft 2026 Integrated System Plan (ISP) identifies 44 potential REZs across the NEM. Victoria, for example, formally declared five onshore REZs and a dedicated shoreline zone for offshore wind in June 2026.
Smart meters, VPPs, and community batteries play a crucial role in maintaining grid stability amidst this influx of variable renewable energy. By coordinating distributed energy resources, they help manage demand spikes, absorb excess solar during peak generation, and provide essential frequency control services to keep the grid balanced.
Costs, Savings & The Catch
While the Solar Sharer Offer provides a pathway to “free” daytime power, understanding the full financial picture is crucial.
Potential Savings:
- Solar Sharer Offer: By strategically shifting high-drain appliances (like EV charging, dishwashers, washing machines, heating, and cooling) into the 3-hour free window, households can significantly reduce their metered consumption during charged periods. For example, pre-heating or pre-cooling your home during the free period can substantially lower evening energy use. Savings will vary but can be substantial for those who adapt their habits.
- VPP Participation: As noted, VPPs offer additional earnings of $100 to over $1,000 annually through bill credits or direct payments, on top of your standard solar savings.
- Federal Battery Rebates: The federal ‘Cheaper Home Batteries’ rebate currently offers approximately $3,700 in upfront STC discounts for a 14kWh battery until 31 December 2026. This rebate is set to decrease significantly from 1 January 2027.
The Catch:
- Higher Rates Outside Free Period: To compensate for the free window, retailers on SSO plans may charge higher rates during peak and shoulder periods, and potentially higher daily supply charges. It’s essential to compare total estimated annual costs, not just the lure of free power.
- Smart Meter Requirement: While smart meters are increasingly common, if you don’t have one, you’ll need one installed to access the SSO. The cost of installation for a new connection or upgrade is often absorbed by the retailer or distributor, but it’s worth confirming any charges.
- Behavioural Shift: Maximising the SSO requires conscious effort to shift energy usage. Without smart home automation, this can be inconvenient. Consider how your household’s daily routine aligns with the free period.

Bottom Line
The Solar Sharer Offer, launching across much of Australia from July 2026, presents a genuine opportunity for households with smart meters to reduce their electricity bills by accessing three hours of free daily power. While not a universal solution, for those able to shift significant energy consumption to the mid-day window, it offers tangible savings.
For homeowners with solar and batteries, integrating with a Virtual Power Plant (VPP) further amplifies these benefits, turning your stored energy into an income stream while supporting grid stability. Combined with existing federal and state battery rebates (like the federal $3,700 rebate for a 14kWh battery in 2026), investing in solar and battery storage, and then connecting to a VPP, offers one of the most effective pathways to energy independence and significant financial returns in Australia’s evolving energy landscape. Always compare specific offers from multiple retailers to ensure the plan aligns with your household’s unique energy consumption patterns and maximises your overall savings.
