Victoria Solar Sharer: Free Midday Power Arrives 1 October 2026

Why Victoria is following NSW, SA and QLD

Victoria has more than 800,000 rooftop solar systems and one of the highest per-capita solar penetrations in the world. On sunny days, wholesale electricity prices in the Victorian region of the National Electricity Market regularly drop to zero — or negative — between roughly 10am and 3pm. Historically, that value has flowed to retailers and generators rather than directly to households.

The Victorian Government's Solar Sharer mirror scheme, announced alongside the Federal package and confirmed to start on 1 October 2026, corrects that imbalance. Retailers must offer at least one residential plan featuring three hours of completely free electricity during the daytime solar peak.

The three-month delay behind NSW/SA/QLD reflects Victoria's separate energy regulator (the Essential Services Commission) and its own default-offer framework (the Victorian Default Offer). Retailers need time to design compliant plans, update billing systems, and reconcile with existing controlled-load tariffs.

What Victorian households should do now (before 1 October)

You have three months to get your home ready to fully harness free midday power on day one. The households that prepare will capture the maximum value; those that wait will need to catch up.

• 1. Audit your appliances for delay-start timers. Dishwashers, washing machines, dryers and pool pumps — anything with a schedule — should be ready to run 11am–2pm from October.
• 2. Move hot water off controlled-load. If you're still on a night-only electric storage tariff (Tariff 31 / 33 equivalents), book an electrician to re-wire onto a midday timer — or replace the tank with a heat pump.
• 3. Retrofit the building shell. Insulation, draught-proofing and double glazing turn your house into a thermal battery — pre-heat or pre-cool during the free window and coast through the evening peak. See our old-home efficiency guide.
• 4. Consider a battery. With free midday charging, home batteries pay back faster than ever — even without solar.
• 5. Book a NatHERS assessment. A rating tells you exactly which upgrades will amplify the Solar Sharer savings most in your specific home — find a Victorian assessor.

Stack the offer with Solar Victoria rebates

Solar Victoria's rebate and interest-free loan programs sit on top of the Solar Sharer Offer — they aren't mutually exclusive. Practical stacks Victorian households should consider:

• • Solar Homes rebate (up to $1,400 for solar PV) + free midday power = charge your battery for nothing during the day and export none of it back to the grid.
• • Hot water rebate (up to $1,000 for heat pump hot water) + free midday power = effectively free hot water for the life of the tank. Full breakdown in our hot water comparison.
• • Reverse-cycle heating rebate (up to $1,000) + free midday power = precondition your home for cents per day in winter.
• • Interest-free battery loans from Solar Victoria pair with the Federal Cheaper Home Batteries Program — the Solar Sharer window collapses battery payback from ~10 years to 5–7.

Batteries: the biggest unlock for Victorian homes

Victoria's evening peak tariffs are among the highest in the country, often 35–48c/kWh between 4pm and 9pm. A 10–13 kWh battery charged for free at midday and discharged across that evening peak can save $1,300–$1,900 per year in Victoria — even before counting any solar generation.

Combine that with the Federal Cheaper Home Batteries Program rebate and Solar Victoria's interest-free loan, and payback in Victoria drops to 5–7 years for most households. See our full rebates and incentives guide.

EV charging: free fuel for the average Melbourne commute

The average Melbourne commute is around 35 km per day, or roughly 7–9 kWh of EV charging. Push that entirely into the Solar Sharer window with a smart wall charger (Wallbox, Zappi, Tesla Wall Connector or similar) and your annual fuel cost drops to near zero — a saving of $1,200–$1,700 per year compared with a petrol car. Retirees, remote workers, and shift workers whose cars sit at home during the day capture this value effortlessly.

Cold-climate homes: pre-heat during the free window

Melbourne, Ballarat, Bendigo and the Victorian High Country all sit in NatHERS climate zones 21, 27, 62 and 63 — heating-dominated climates where a poorly-sealed home can bleed the free midday power in under an hour. The Solar Sharer Offer works best in tandem with:

• • Ceiling insulation topped up to R6.0 or higher.
• • Draught-sealing of exhaust fans, downlights, wall vents and skirting gaps (blower door testing recommended — see our blower door guide).
• • Double glazing or secondary glazing on north and west windows.
• • A well-sized reverse-cycle heat pump run hard from 11am–2pm on cold mornings.

A leaky Victorian weatherboard with no ceiling insulation will waste 60–80% of the free midday heating value within two hours. The same home retrofitted to a NatHERS 7-star equivalent shell will hold that warmth deep into the evening peak.

Things Victorians should watch out for

• • Victorian Default Offer comparison. Always benchmark any Solar Sharer plan against the current VDO for your distribution zone. A "free" window with high peak rates can be worse overall.
• • Feed-in tariffs may drop. Expect some retailers to reduce solar feed-in credits on Solar Sharer plans. High solar exporters should model carefully.
• • Time-of-use vs flat tariffs. Solar Sharer plans will almost certainly be time-of-use. If your household consumes heavily during the evening peak, the free window may not fully compensate.
• • Not every retailer will be competitive. The mandate requires one compliant plan — not the best plan. Use Victorian Energy Compare (compare.energy.vic.gov.au) from October to find the sharpest offer for your postcode.
• • Controlled-load conversions cost money. Moving hot water off Tariff 31/33 onto a midday timer usually needs an electrician — factor in $200–$500 for the switchover.

The Victorian gas-to-electric case just got stronger

Victoria has the highest household gas connection rate in Australia — over 2 million homes. Gas hot water, gas cooktops and gas ducted heating have historically been the "cheap" choice. That's changing fast.

Wholesale gas prices in Victoria have doubled since 2020, daily supply charges are climbing, and no new gas connections are permitted for new residential subdivisions. The Solar Sharer Offer is the tipping point: a heat pump running on free midday electricity is dramatically cheaper than gas, and induction cooking on a time-shifted schedule outperforms gas on both cost and indoor air quality.
