Introduction
If you’re a Queensland homeowner thinking about a battery, the main incentive available in 2026 is the federal Cheaper Home Batteries Program. Queensland’s own Battery Booster rebate has closed, so this guide explains what you can claim now, who’s eligible and how the discount is calculated.
What happened to Queensland's Battery Booster rebate?
Queensland’s Battery Booster program offered means-tested rebates of $3,000 or $4,000 for eligible households in 2024. That program has now closed. For current support, Queensland homeowners can look to the federal Cheaper Home Batteries Program, and it’s worth checking the Queensland Government website for any new state programs.
What is the Cheaper Home Batteries Program?
The Cheaper Home Batteries Program is the Australian Government’s home battery discount. It started on 1 July 2025 and is delivered through the Small-scale Renewable Energy Scheme, administered by the Clean Energy Regulator.
Eligible batteries create small-scale technology certificates (STCs) based on their usable capacity. Your installer usually applies the value of those certificates as an upfront discount on your quote.
In December 2025, the government expanded the program’s estimated funding from $2.3 billion to $7.2 billion and announced changes designed to keep the discount at around 30% across different battery sizes.
How much is the battery rebate worth?
The discount depends on two things: how much usable capacity your battery has, and when it’s installed.
Battery size. Since 1 May 2026, larger batteries earn STCs at a reduced rate for their extra capacity:
| Usable capacity | STC rate applied |
|---|---|
| Up to 14 kWh | 100% |
| Each kWh above 14, up to 28 kWh | 60% |
| Each kWh above 28, up to 50 kWh | 15% |
| Above 50 kWh | No STCs |
Installation date. The number of STCs per kWh (the STC factor) steps down every six months until the end of 2030:
| Period | STC factor (STCs per kWh) |
|---|---|
| May–Dec 2026 | 6.8 |
| Jan–Jun 2027 | 5.7 |
| Jul–Dec 2027 | 5.2 |
| Jan–Jun 2028 | 4.6 |
| Jul–Dec 2028 | 4.1 |
| Jan–Jun 2029 | 3.6 |
| Jul–Dec 2029 | 3.1 |
| Jan–Jun 2030 | 2.6 |
| Jul–Dec 2030 | 2.1 |
For example, a battery with 10 kWh of usable capacity installed between May and December 2026 creates about 68 STCs (10 × 6.8). STC prices move with the market, so the dollar value of the discount changes over time. Your installer’s quote should show the discount clearly.
Who is eligible for the battery rebate?
To qualify, your battery must:
- Be between 5 and 100 kWh nominal capacity. Only the first 50 kWh of usable capacity earns STCs.
- Be installed with a new or existing solar system of up to 100 kW.
- Be new, and not previously installed or claimed.
- If grid-connected, be able to take part in a virtual power plant, along with its inverter. You don’t have to join one.
- Be on the Clean Energy Council’s approved products list.
- Be installed by an installer accredited by Solar Accreditation Australia with a battery endorsement.
Only one battery system per property can receive STCs. You can add capacity later if your existing battery hasn’t claimed STCs and the total stays at or under 100 kWh. Off-grid systems have their own rules.
How do you claim it?
Most households don’t need to apply directly. When you buy through an accredited installer, they create the STCs and take their value off your quote, so the saving is upfront. Check that your quote lists the battery’s usable capacity and the discount applied.
How does home battery storage work?
If you’re wondering how solar batteries work or what their benefits are, here is a quick overview:
- Solar panels capture abundant sunlight during the day and convert it into electricity to power your home. Any excess solar energy gets exported back to the grid.
- Battery storage systems allow you to capture even more of your solar energy production. Quality lithium batteries can store many hours worth of unused solar electricity from your panels.
- Then when the sun goes down or demand spikes, the stored solar energy discharges from the batteries to keep powering your home. This gives you access to free solar energy around the clock, not just when the sun is out.
- Benefits like maximizing solar usage, avoiding peak energy rates, and having backup power during grid outages are what make adding solar batteries so advantageous.
- And by offsetting far more of your overall electricity usage with free solar power, batteries are estimated to save the typical Queensland household nearly $650 a year on their energy bills!
Is a battery right for your home?
A battery that’s too large or too small can reduce your savings, so it’s worth checking a few things first:
- Your daily energy use, especially in the evening.
- Your solar system size and inverter limits.
- Whether your home is single phase or three phase.
- Future plans, such as an EV or more air conditioning.
