The NSW solar battery rebate for households has ended, so the main saving today is the federal Cheaper Home Batteries Program, which takes around 30% off an eligible battery installation. You can stack the NSW virtual power plant (VPP) incentive on top of it. Your discount rate is fixed by the date your compliance certificate is issued, and that rate drops on 1 January 2027, then keeps stepping down every six months until 2030.
Across the Central Coast and Hunter on the Ausgrid network, Restore Electrical installs and upgrades home batteries and integrates them with existing solar systems. The federal discount has its own conditions: the Clean Energy Regulator requires solar, a VPP-capable battery and a Solar Accreditation Australia (SAA) installer with battery endorsement, and allows one claim per premises. This guide covers what replaced the NSW rebate, how the discount is calculated, eligibility, the VPP incentive and the Ausgrid connection steps.
NSW Battery Rebate Changes in 2026
The NSW battery installation discount that many households still search for is no longer available, according to Energy NSW in an update dated 1 July 2026. It also notes the federal Cheaper Home Batteries Program started on 1 July 2025, and one battery can’t claim both the NSW and federal installation discounts.
That said, a home battery still attracts government support in NSW, just through other schemes now. Here’s what’s available to NSW households today, and who each option suits:
- Federal Cheaper Home Batteries Program: Redesigned on 1 May 2026, it offers around 30% off batteries from 5 to 100 kWh, according to the federal energy department. You don’t apply to government; instead, the installer or retailer gives you an upfront reduction or a rebate after installation.
- NSW VPP incentive: Energy NSW’s VPP incentive is still available and can sit on top of the federal discount once you join a participating virtual power plant.
- Not for single homes: From 1 September 2026, the NSW Government announcement says a separate discount covers businesses and apartment buildings with four or more units. Those apartment batteries must be 20 to 200 kWh, so a standalone house doesn’t fit either group.
For a standalone home, then, the federal discount is the main saving. Its value comes down to a simple calculation worth doing before any battery installation.
Cheaper Home Batteries Discount and STC Factors
Two details decide how many certificates your battery earns: its usable capacity and the date on your compliance certificate. Usable capacity can sit below the nominal figure on the label, so the eligibility rules count a 10 kWh battery at 90% depth of discharge as 9 kWh. Those rules also treat a battery as installed on the day its certificate of electrical compliance is issued.
That date matters because the federal schedule gives 6.8 small-scale technology certificates (STCs) per usable kWh to a battery certified by 31 December 2026, then 5.7 from 1 January 2027. A battery with 10 kWh usable would earn about 68 STCs if certified by 31 December 2026, or about 57 from 1 January 2027. Bigger batteries earn less per extra kWh: the full factor covers only the first 14 kWh, then 60% to 28 kWh and 15% to a 50 kWh cap.
To estimate your own system, the Clean Energy Regulator points to the official REC Registry STC calculator. It also publishes the full schedule of STC factors by installation period:
| Installation period | STCs per usable kWh |
| May to December 2026 | 6.8 |
| January to June 2027 | 5.7 |
| July to December 2027 | 5.2 |
| January to June 2028 | 4.6 |
| July to December 2028 | 4.1 |
| January to June 2029, then July to December 2029 | 3.6, then 3.1 |
| January to June 2030, then July to December 2030 | 2.6, then 2.1 |
Dollar values vary between quotes, so ask for the discount as its own line before you sign. A certificate dated from 1 January costs you a full step, even if you signed months earlier.
Battery Rebate Eligibility for Central Coast Homes
One claim per address, ever. The Clean Energy Regulator allows only one battery to claim STCs at each premises, so if you start small, a bigger battery added later can’t claim at all.
Before settling on a size, check your home and quoted system against these five conditions, because missing any one rules the battery out:
- Solar required: A battery without solar, storing only grid power, isn’t eligible under the federal eligibility rules. New or existing solar both count.
- VPP-capable, not VPP-bound: The battery and its inverter must be able to join a virtual power plant, though those same rules don’t require you to join one.
- Approved products: The battery must be on the Clean Energy Council approved list, and existing solar must comply with state electrical safety rules, according to the regulator’s requirements. An inverter that isn’t VPP-capable and CEC-listed must be replaced, for example with hybrid inverter upgrades.
- Accredited installer: The eligibility information requires installation by, or under on-site supervision of, an SAA-accredited battery installer, with wiring by a licensed electrician. Ask any installer for proof of SAA accreditation with battery endorsement, and check their NSW licence on the Service NSW website.
- Stays put: Under Clean Energy Regulator rules, the battery must stay at your premises until after 2030 or the end of its warranty, whichever is later.

The NSW VPP Incentive on Top of the Federal Discount
Can you stack a NSW payment on the federal discount? Yes: the Energy NSW VPP incentive page says batteries up to 50 kWh installed under the Cheaper Home Batteries Program may be eligible. The payment depends on the capacity you make available to the grid, counted only up to 28 kWh, and can arrive upfront, in instalments or as bill credit.
On the dollar side, the NSW Government announcement of 18 August 2026 sets the incentive at up to $1,000 for eligible homes that join a VPP.
Four conditions in the incentive rules decide whether you can claim, so check each one while comparing offers:
- Battery size: Under the incentive rules, the battery must be 2 to 50 kWh, a ceiling that applies from 1 July 2026.
- A participating provider: You must use a VPP provider offering the incentive, and since not every retailer supports VPPs, you may need to switch.
- Signed paperwork: You sign a nomination form before any payment, then your provider gives you a cooling-off period.
- One claim only: It’s paid once per National Metering Identifier. Households that claimed between 1 November 2024 and 30 June 2025 can’t claim again, and apartment-building batteries are excluded, per Energy NSW.

Shortlist VPP-capable solar battery systems from day one, since both incentives depend on it. The federal discount rate is fixed by your certificate date, whereas the VPP payment depends on your provider contract.
Ausgrid Battery Connection Steps for Central Coast Homes
Most connection paperwork is the installer’s job, but knowing the steps keeps your install date, and your STC factor, on track. These four stages sit between your quote and switch-on for homes on the Ausgrid network:
Network Approval Before Switch-On
Ausgrid requires approval before a solar or battery system is switched on, and in most cases the installer manages it, according to Ausgrid’s solar guidance. We lodge battery submissions with Ausgrid, including testing and photos, and hold Level 2 ASP accreditation 6611 for isolations and metering. Read more about our licensed team.
Smart Meter and Smart Inverter
Under Ausgrid’s network rules, all new and upgrading solar systems require a smart meter, so book a smart meter installation first if your home doesn’t have one. From late 2026, new and upgraded systems also need an internet-connected smart inverter. If it loses connection for an extended period, exports are limited to 1.5 kW.
Switchboard Readiness
The NSW Government battery guide says homes with an outdated switchboard may need an upgrade before a solar and battery installation. It also recommends your installer places a smoke detector near the battery. If your board is ageing, schedule the switchboard upgrade early so it doesn’t hold up the battery.
Compliance Certificate Date
Once wiring is finished, the licensed electrician issues the Certificate of Compliance for Electrical Work, and that date sets your STC factor. STCs must then be created within 12 months of it, under the federal eligibility rules. Every earlier step feeds into that one date.
Conclusion
If a battery is on your list, plan around 1 January 2027. That’s when the regulator’s STC table drops from 6.8 to 5.7 certificates per usable kWh. Because your compliance certificate date sets the rate, an install that slips past New Year earns fewer certificates, and the factor keeps falling every six months to 2030.
With the NSW household discount gone, the federal battery discount of around 30% does the heavy lifting, and the NSW VPP payment can be added once you join a provider. To qualify, pair the battery with solar, choose VPP-capable, CEC-listed hardware and use an SAA-accredited installer with battery endorsement, plus licensed wiring. Size it carefully the first time, since each home gets a single claim.

Frequently Asked Questions About the NSW Solar Battery Rebate
Is there still a battery rebate in NSW in 2026?
Not for households from the NSW Government, whose installation discount has ended. The federal Cheaper Home Batteries Program offers around 30% off, and the NSW VPP incentive stacks on top.
When does the solar battery rebate drop next?
On 1 January 2027, the STC factor falls from 6.8 to 5.7 per usable kWh. After that it steps down every six months, and your rate is set by your compliance certificate date.
Can I get the federal battery discount and the NSW VPP incentive together?
Yes. Batteries up to 50 kWh under the Cheaper Home Batteries Program may qualify once you join a participating VPP provider. The NSW Government’s 18 August 2026 announcement says up to $1,000.
Can I add a battery to my existing solar system and still get the discount?
Yes, existing solar qualifies as long as it complies with state electrical safety rules. The inverter the battery connects to must be VPP-capable and CEC-listed, otherwise it has to be replaced.
Do I have to join a virtual power plant to get the federal discount?
No. The battery and inverter must be technically capable of joining a virtual power plant, but taking part in one isn’t a condition of the federal Cheaper Home Batteries discount.
When does the Cheaper Home Batteries Program end?
It ends in 2030. The final period is July to December 2030, when the factor sits at 2.1 STCs per usable kWh, so an earlier install earns more certificates.
