Two major electricity changes took effect for NSW households on 1 July 2026. First, the Australian Energy Regulator (AER) finalised its Default Market Offer (DMO) 8 determination. This reduced residential standing-offer electricity prices across all three NSW distribution zones.
Second, every retailer in the DMO area must now offer the Solar Sharer Offer (SSO). This new opt-in plan gives households with smart meters three hours of free electricity every day from 11 am to 2 pm, with a daily limit of 24 kWh.
If you have solar panels, a home battery, or both, these changes could work together to significantly reduce your annual electricity bill. In addition, the federal Cheaper Home Batteries Program remains available through 2030, and its rebate continues to provide substantial savings after May 2026.
This article explains what these changes mean for NSW households. It also provides a practical framework to help you maximise savings during the 2026–27 financial year.
What Is the Solar Sharer Offer (SSO)?
The Solar Sharer Offer is a regulated, opt-in electricity plan introduced as part of the DMO 8 framework. Its core mechanic is straightforward: eligible households receive a three-hour window of free electricity — 11 am to 2 pm daily in NSW — capped at 24 kWh per day. That cap is well above the midday consumption of most households; the CSIRO estimates average five-person household daily use at around 20 kWh, meaning the cap is unlikely to be an issue for most families.
Importantly, you do not need rooftop solar to access the SSO. Renters are eligible, provided they have a smart meter installed. If you do not currently have a smart meter, contact your retailer—for most NSW households, smart meter installation is available at no upfront cost.
The SSO is designed to solve a structural challenge in the National Electricity Market. Australia now has more than 4.2 million rooftop solar systems, generating over 25 GW of daytime capacity. As a result, wholesale electricity prices often fall to zero or even become negative during the middle of the day. Instead of letting this excess solar energy go to waste, the SSO passes the cost savings directly to households that can shift their electricity use into the free energy window.
What Is the DMO 8 and How Much Can NSW Households Save?
The Default Market Offer (DMO) is the regulated benchmark price set by the AER each year. It acts as a safety net for the roughly 8% of NSW households — approximately 463,000 customers nationally — who remain on standing-offer electricity plans. It also functions as a comparison reference price that helps all electricity customers evaluate market offers.
The AER’s Final DMO 8 Determination, released 26 May 2026, confirmed residential price reductions across all three NSW distribution zones from 1 July 2026. The reductions were driven by lower wholesale electricity costs, reduced environmental scheme costs, and declining retail operating expenses.
NSW DMO 8 Residential Savings at a Glance
For the Ausgrid zone (Sydney Metro): flat-rate customers save -3.4% (up to $89/yr); TOU customers save -3.7% (up to $97/yr).
Endeavour Energy zone (Greater Western Sydney/Blue Mountains): flat-rate customers save -3.4% (up to $79/yr); TOU customers save -4.5% (up to $105/yr).
Essential Energy zone (Regional NSW): the largest savings—flat-rate customers save -5.0% (up to $137/yr); TOU customers save -7.7% (up to $211/yr). This zone benefits most from the correction of elevated wholesale costs that disproportionately affected regional NSW in 2022–24.
These savings apply to standing-offer customers. If you are on a competitive market offer—and you should be—you may already be paying up to 20% below the DMO. The DMO’s value is as a benchmark for comparing plans on the Australian Government’s free comparison tool, Energy Made Easy.
The Federal Cheaper Home Batteries Program—Still Active in FY2026–27
The Cheaper Home Batteries Program is a $7.2 billion federal initiative. It provides an upfront discount of approximately 30% on eligible home battery systems ranging from 5–100 kWh. The program is delivered through the Small-Scale Renewable Energy Scheme (SRES). The discount is applied at the point of sale, so there is no separate application process. There is also no means test, making the program available to all eligible households and businesses.
What changed on 1 May 2026: The STC factor dropped from 8.4 to 6.8 per kWh of usable capacity, and a new tiered structure was introduced for larger batteries. Specifically:
- Tier 1 (0–14 kWh): Full STC rate — approximately $252–$272 per usable kWh in NSW (Zone 3)
- Tier 2 (14–28 kWh): 60% of the full rate applies
- Tier 3 (28–50 kWh): Only 15% of the full rate applies
For a standard 10 kWh battery, the current rebate is approximately $2,720 (post-May 2026, at ~$272/kWh). The rebate will step down again on 1 January 2027, so FY2026–27 represents the highest available value under the current schedule. The program runs through 2030.
NSW Rebate Stacking — How to Maximise Your Battery Savings
NSW households can combine several incentives to maximise their savings. By stacking these incentives correctly, you can make one of the smartest financial decisions when investing in home battery storage.
Available NSW Incentive Stack
- Federal Cheaper Home Batteries Program: ~$2,720 for a 10 kWh system (post-May 2026), applied as a point-of-sale discount by your accredited installer
- NSW VPP Incentive (PDRS): Up to $1,500 for households who connect their battery to an approved Virtual Power Plant (VPP). Stackable with the federal rebate
- NSW Home Energy Saver — Interest-Free Loan: Up to $15,000 for eligible households (income under $210,000/yr, repaid over 10 years). A targeted discount of up to $4,000 is available for lower-income households or concession-card holders
An eligible NSW household can access more than $5,720 in combined support by installing a 10 kWh battery, before factoring in any electricity bill savings. Eligibility conditions apply. Speak to an accredited installer or visit energy.gov.au for more details.
Which Strategy Suits Your Household? A Practical FY2026–27 Framework
Not every NSW household benefits from every option. The right strategy depends on your usage pattern, whether you have solar, and what tariff you are currently on. Here is a straightforward framework to guide your decision.
Strategy 1 — Solar Sharer Offer Only
Best for renters, apartment residents, or any household without solar panels who can shift appliance use to the 11 am–2 pm window. Running your dishwasher, washing machine, pool pump, or EV charger during the free window is where the savings are. On the Essential Energy TOU tariff, this strategy alone could save up to $211 per year.
Strategy 2 — Existing Solar + Battery
Best for households with an existing solar system that generates strong daytime output. A home battery stores surplus solar generated during the free window and discharges it during the 5–9 pm evening peak—when grid electricity typically costs 36 cents or more per kWh. Consequently, well-sized households can reduce grid dependency by 60–80%.
Strategy 3 — Solar + Battery + SSO (The Optimal Stack)
The most powerful combination for eligible households. During the 11 am–2 pm free window, the battery charges from the grid at zero cost. Any surplus solar is exported to the grid at feed-in tariff rates (currently 4–10 c/kWh across NSW retailers). In the evening, the battery discharges — avoiding peak rates. Joining a VPP adds a potential $1,500 incentive and ongoing grid participation revenue. This strategy delivers the maximum possible reduction in annual electricity bills.
A Real-World NSW Example — The Kumar Family in Parramatta
Consider a four-person household in Parramatta (Endeavour Energy zone) on a TOU standing offer, using 15 kWh per day with most usage in the evenings. Prior to FY2026–27, their annual electricity bill was approximately $2,328 (DMO 7 TOU reference price).
Under DMO 8, their standing-offer TOU price drops by -4.5%, saving approximately $105 per year automatically—without changing a thing.
By switching to the Solar Sharer Offer and shifting their dishwasher, washing machine, and air-conditioner pre-cool to the 11 am–2 pm window (about 3 kWh per day), they capture an additional estimated saving of $130–$180 per year.
They add a 10 kWh solar battery using the federal rebate (~$2,720 discount), reducing their out-of-pocket cost to approximately $5,000–$6,000 after the rebate. Their evening grid draw drops from roughly 9 kWh to 1–2 kWh per night. Annual electricity bill savings from the battery alone are estimated at $800–$1,200, suggesting a payback period of approximately 5–7 years under current tariffs.
This is a simplified illustrative example. Actual outcomes depend on household usage, system size, tariff structure, solar exposure, and other factors. See our contact page to get personalised advice for your home.
The Smart Meter Requirement — What NSW Households Need to Know
Access to the Solar Sharer Offer requires a smart meter. Smart meters record electricity usage at 30-minute intervals and transmit data to your retailer, enabling time-of-use billing. Without a smart meter, TOU plans — including the SSO — are not accessible.
The good news: for most NSW households, smart meter installation is available free of charge through your electricity retailer or distributor. Contact your retailer and ask specifically about smart meter installation ahead of the 1 July 2026 SSO launch. If you are with a retailer offering 10 or fewer customers, they may not be required to offer the SSO, but most major retailers are participating.
Frequently Asked Questions
No. The Solar Sharer Offer is available to all NSW households in DMO-regulated zones with a smart meter, regardless of whether you have solar panels. Renters are also eligible.
The SSO provides free electricity between 11 am and 2 pm, up to 24 kWh per day. However, the overall plan cost is calibrated to equal the DMO TOU reference price — meaning rates outside the free window are approximately 1–4 cents per kWh higher than a standard TOU plan. Households that can shift usage to the free window benefit; those who cannot may find a standard market offer more cost-effective.
Yes. The Cheaper Home Batteries Program runs through 2030. Post-May 2026, the rebate is approximately $252–$272 per usable kWh for systems under 14 kWh (Zone 3 NSW). The next step-down is 1 January 2027, so the current half-year window offers the highest available rebate in FY2026–27.
Yes. The federal Cheaper Home Batteries Program is stackable with the NSW VPP Incentive (up to $1,500) and the NSW Home Energy Saver interest-free loan (up to $15,000 for eligible households). Eligibility conditions apply.
Usage above the 24 kWh daily cap during the free window is charged at the applicable ‘reasonable use rate’, as set out in your Energy Price Fact Sheet. For most households, 24 kWh far exceeds midday consumption, so hitting the cap is unlikely.
Use the Australian Government’s free, independent comparison tool at energymadeeasy.gov.au. From July 2026, retailers must list their Solar Sharer Offer plans on the site. Compare the off-peak rates, daily supply charges, and any feed-in tariffs included with the SSO.
Your FY2026–27 Energy Action Plan — 5 Steps
- Step 1 — Check your smart meter status. Contact your retailer to confirm you have a smart meter, or arrange installation (free for most NSW households).
- Step 2 — Map your usage pattern. Review your electricity bills from the last three months. If you can shift more than 20–30% of your electricity use to the 11 am–2 pm window, you will likely benefit from the Solar Sharer Offer.
- Step 3 — Compare plans on Energy Made Easy. Use energymadeeasy.gov.au to compare your current plan against available Solar Sharer offers in your zone.
- Step 4 — Get at least 3 battery quotes. If you are considering a battery, compare a minimum of three written quotes from accredited installers. Ask each installer to confirm the federal rebate amount, any VPP incentive, and your eligibility for the NSW Home Energy Saver loan.
- Step 5 — Act before 1 January 2027. The federal battery rebate steps down again on 1 January 2027. If you are ready to proceed, the current second half of FY2026–27 offers the best available rebate under the post-May 2026 schedule.
