Yes—at least in principle. The Australian Government’s upcoming Cheaper Home Batteries Program, launching on 1 July 2025, is designed to stack with existing state and territory battery incentives. For NSW residents, this means you could combine the federal rebate of ~$372 per kWh with the state-level Peak Demand Reduction Scheme (PDRS) battery discount.
However, while this "stacking" is a clear policy intent, the fine print—particularly how NSW will operationalise compatibility—is still being finalised. Homeowners considering a battery should follow updates closely and ensure their system is eligible under both programs.
How does the federal battery subsidy interact with existing state-based incentives?
Unlike many proposed incentives, the Cheaper Home Batteries Program is locked in as an active government initiative, aiming to make solar batteries more affordable for over one million households and businesses across Australia.
Here’s what’s confirmed so far:
- Start date: 1 July 2025
- Rebate value: Around $372 per kWh of usable battery capacity (roughly $3,500–$4,000 for a typical 10–13.5 kWh system)
- Eligibility:
◦ New solar-connected home batteries
◦ VPP-capable systems (Virtual Power Plant)
◦ 5kWh–50kWh usable capacity
◦ Installed by CEC-accredited professionals
- No means testing is currently planned
- Delivery: Expansion of the Small-scale Renewable Energy Scheme (SRES)
This rebate could make products like SigenStor batteries or Tesla Powerwalls significantly more affordable, especially when paired with inverters from brands like Sungrow or Fronius.
What about NSW’s Peak Demand Reduction Scheme?
NSW’s PDRS battery rebate is part of a broader demand response strategy, offering upfront discounts on eligible battery systems to help stabilise the grid. These discounts, expected to range from $1,600 to $2,400, may be available from 1 November 2024, subject to final rollout timelines.
The PDRS aims to lower electricity demand during peak periods and requires batteries to be VPP-ready and installed by approved providers. This aligns well with federal criteria—a promising sign for integration.
How will the federal and NSW rebates work together? Policy intent: Stacking is the goal
The federal government has clearly stated that its rebate is designed to stack with existing state and territory programs, including NSW’s. This means homeowners could benefit from both, dramatically reducing the out-of-pocket cost of a battery.
For example:
- A 10 kWh VPP-capable battery system may attract:
◦ ~$3,720 from the federal rebate
◦ ~$1,600–$2,400 from the NSW PDRS
◦ Total savings: Up to $6,000 or more
However, the final implementation details are still pending.
What still needs to be confirmed?
While policy alignment looks promising, there are three critical components that need to fall into place:
- Official state confirmation
The NSW Government must formally confirm that PDRS rebates can be combined with the federal program. This could require minor regulatory adjustments to the PDRS rules.
As of early 2025, government communications suggest collaboration is underway, but NSW hasn’t yet issued a final go-ahead.
- Aligned eligibility criteria
The good news: both schemes require CEC-accredited installation, approved battery brands, and VPP capability. This makes it likely that a compliant system will qualify for both.
Still, homeowners should double-check that:
- The battery is on CEC’s approved list
- The system is VPP-compatible
- The installer is up-to-date with both schemes’ criteria
- Streamlined administration
For stacking to work in practice, it’s important that:
- Installers can guide homeowners through both processes
- Claims are not overly complex or duplicated
- Any timing gaps between state and federal programs are clearly explained
It’s possible that solar retailers will offer “bundled rebate” quotes once both schemes are live— this is a trend seen in other solar rebate programs.
Why combining rebates matters
Combining the federal and NSW rebates could reduce battery costs by 30–50%, significantly improving the payback period and making batteries accessible to more households. That matters because:
- Batteries cut electricity bills by storing cheap solar energy for evening use
- Grid-connected batteries can support the energy system during peak demand
- Virtual Power Plants (VPPs) help stabilise the grid and unlock extra value for users
And from an environmental perspective, battery uptake supports deeper solar penetration and helps Australia transition away from fossil fuels.
What should NSW homeowners do next?
Here’s how to plan smartly ahead of July 2025:
- Stay informed: Monitor updates from the NSW Energy Department and the federal DCCEEW.
- Choose eligible tech: Look for batteries like SigenStor, Tesla Powerwall, or Enphase IQ Battery that are VPP-ready and CEC-listed.
- Engage early: Talk to a CEC-accredited installer about planning your system to meet both state and federal requirements.
- Be rebate-timing aware: Consider whether it’s worth waiting until July 2025 to access both incentives, especially if your current energy bills aren’t urgent.
Final word
The Cheaper Home Batteries Program is a game-changing federal initiative that’s designed to stack with NSW’s battery rebate, making batteries more affordable than ever. While the intent is clear, homeowners should watch for final confirmation from the NSW Government to ensure both incentives can be claimed seamlessly.
