You might have heard about changes to the rebate in May and now wonder if you missed your chance. Maybe you got a quote last year but waited, or a neighbour told you something and you’re unsure what’s accurate.
The federal battery rebate is still available. The Cheaper Home Batteries Program is open and you can claim it now.
The way the rebate is calculated changed in May 2026, especially for larger batteries. However, the program will keep running until 2030.
Since July 2025, PSC Energy has helped thousands of NSW homeowners claim the federal battery rebate and navigate every program change.

By the end of this article, you understand what’s changed and what’s still happening with the federal solar battery rebate.
What Changed with the Federal Government Battery Rebate in May 2026 and What Stayed the Same
The federal battery rebate didn’t end in May 2026, but two things did change.
Here’s what changed with the federal home battery rebate:
- The STC factor dropped from 8.4 to 6.8. The STC factor is the number the government uses to calculate your rebate. A lower STC factor means a smaller rebate per kilowatt-hour.
- A tiered structure was introduced, so larger batteries now get a lower rebate per kilowatt-hour than smaller ones.
And here’s what parts of the rebate stayed the same:
- The program is still available to NSW homeowners with solar panels.
- You still don’t need to fill out any forms. Your installer will handle the rebate claim for you.
- The rebate still comes off your quote upfront, before you sign.
- Batteries up to 14 kWh still get the full rebate rate.
The government made these changes to help the program’s budget last longer.
Battery sizes grew faster than expected, rising from an average of 10 to 12 kWh in 2024 to 28 kWh by late 2025. Larger batteries were using more of the rebate pool than planned.
To keep the program running until 2030, funding increased from $2.3 billion to $7.2 billion, supporting over 2 million battery installations across Australia.

How Much Is the Federal Battery Rebate Worth Right Now?
The rebate is about $238 per usable kilowatt-hour (kWh) of storage for the first 14 kWh. For bigger batteries, the rebate amount is tiered.
Here’s what the rebate looks like for some common battery sizes right now:
- 10 kWh battery: about $2,380 off.
- 13.5 kWh Tesla Powerwall 3: about $3,210 off.
- 24 kWh SigenStor system: about $4,760 off.
- 50 kWh system: about $6,120 off (this is the largest size that qualifies for a rebate).
Your installer will take this discount off your quote before you sign. This way, you don’t have to pay the full price and wait for a refund. The discount should be clearly shown on your paperwork. If it isn’t, ask your installer to explain it.
How the Federal Battery Rebate Gets Calculated
The rebate uses a system called Small-scale Technology Certificates (STCs), which work like virtual tokens. Each STC is currently worth about $35.
The Clean Energy Regulator sets the STC factor. From 1 May 2026 to 31 December 2026, it’s 6.8. This means each 1 kWh of usable storage earns 6.8 STCs, up to the first 14 kWh.
Here’s the maths for a 10 kWh battery:
- 10 kWh x 6.8 = 68 STCs
- 68 STCs x $35 = $2,380 rebate
After 14 kWh, the tiered structure reduces how many STCs each additional kWh earns:
- 0 to 14 kWh: full STC factor (100%)
- 14 to 28 kWh: 60% of the STC factor
- 28 to 50 kWh: 15% of the STC factor
- Above 50 kWh: no rebate
Your installer will claim the STCs and subtract their value from your quote.

When Does the Federal Battery Rebate Drop Again?
The rebate drops every six months until 2030. Here’s the schedule:
| May to Dec 2026 | 6.8 |
| Jan to Jun 2027 | 5.7 |
| Jul to Dec 2027 | 5.2 |
| Jan to Jun 2028 | 4.6 |
| Jul to Dec 2028 | 4.1 |
For a 10 kWh battery, the rebate will drop from about $2,380 now to about $1,995 in January 2027. That’s $385 less for the same system in just six months. The longer you wait, the smaller the rebate will be.
Can You Stack the Federal Battery Rebate with the NSW VPP Incentive?
Yes, NSW homeowners can combine the federal battery rebate with another incentive called the NSW VPP Incentive. This is one of the biggest benefits for NSW residents right now.
The NSW Peak Demand Reduction Scheme ended on 30 June 2025 and was replaced by the NSW VPP Incentive on 1 July 2025. This new incentive gives you a one-time upfront payment for connecting your battery to a Virtual Power Plant (VPP).
A VPP is a network of home batteries connected by software. During peak demand, the network uses stored energy from each battery to help support the grid, and you get paid in return.
Here’s what the NSW VPP Incentive pays based on battery size:
- Around $550 for a 10 kWh battery.
- Around $1,500 for a 27 kWh battery.
- About $55 per usable kWh.
To qualify for the NSW VPP Incentive:
- Your battery must have a capacity between 2 kWh and 28 kWh.
- You must connect through an Accredited Certificate Provider (ACP), usually your energy retailer.
- You must have solar panels and be grid-connected.

Which Batteries Qualify for the Federal Battery Rebate?
To qualify for the federal rebate, your battery must meet all of the following:
- Have a usable storage capacity between 5 kWh and 100 kWh.
- Appear on the Clean Energy Council (CEC) approved product list.
- Be installed by an installer accredited through Solar Accreditation Australia (SAA).
- Be VPP-capable, meaning it can connect to a Virtual Power Plant.
- Pair with solar panels, either a new system or an existing one.
The most common batteries that currently qualify include:
- Tesla Powerwall 3 (13.5 kWh, single-phase only)
- Enphase IQ Battery 5P (5 kWh modules, stackable to larger sizes)
- Sigenergy SigenStor (8 kWh modules, available in single or three-phase)
For the NSW VPP Incentive, your battery must also fall between 2 kWh and 28 kWh, and you must actually join a VPP.
- The federal rebate only requires VPP capability.
- The VPP incentive requires VPP participation.
Older batteries and some smaller brands may not be eligible.

How to Claim Both Rebates
Both rebates are applied upfront. You don’t need to fill out forms or wait for any reimbursements.
For the federal battery rebate:
- Your installer calculates the STCs and deducts the value from your quote.
- The discount shows as a line item on your paperwork before you sign.
- If the rebate isn’t listed separately on the quote, ask your installer why.
For the NSW VPP Incentive:
- You enrol with an Accredited Certificate Provider, usually your energy retailer.
- The ACP pays the incentive as an upfront credit, a bill credit, or in instalments, depending on their terms.
Is It Still Worth Getting a Solar Battery in NSW?
The rebate is smaller than it was before May 2026, but the program still cuts your upfront cost and makes financial sense for most NSW homeowners in the right situation.
A battery pays off faster if you:
- Use most of your power in the evenings after the sun goes down.
- Pay between $400 and $500 per quarter for electricity.
- Have solar panels and export a lot of power to the grid during the day.
- Live in an area that experiences regular blackouts.
For most NSW households, payback takes about 5 years, depending on your usage, battery size, and which rebates you claim.
Together, the two rebates can save you between $2,900 and over $7,600 upfront, depending on your battery size.

Wrapping Up: Ohm In on Your Rebate Before It Drops
The rebate alone shouldn’t decide if a battery is right for your home. A battery that matches your actual evening usage will pay off faster than a bigger one chosen just for a larger rebate.
To get the most from both rebates, aim for a battery between 5 and 14 kWh. Every kWh in that range gets the full federal rebate and a good share of the NSW VPP Incentive.
