Since the Cheaper Home Batteries Program launched in July 2025, Australia has been in the middle of a full-blown home battery boom. What was expected to be a steady, decade-long rollout has instead turned into one of the fastest-moving energy programs the country has seen.
In this guide, we’ll break down how popular the rebate has been so far, what the numbers actually look like, why the funding may not last to 2030, and what this means if you’re thinking about adding a battery to your solar system.
Quick recap: What is the Cheaper Home Batteries Program?
The Cheaper Home Batteries Program is a federal initiative designed to cut the upfront cost of installing a home or small business battery by around 30 percent. The rebate is based on the battery’s usable capacity and is set to gradually reduce each year until 2030.
Batteries installed under the scheme must meet strict safety standards, be on an approved products list, and be VPP-ready, meaning they can participate in a Virtual Power Plant if the owner chooses.
For NSW households, this federal support can stack with the NSW Virtual Power Plant incentive, which offers an additional upfront payment when you connect an eligible battery to a participating VPP.
By the numbers: A rebate that took off faster than expected
The popularity of the rebate has been described as “off the charts”, and the data backs that up.
Shortly after launch, media reports noted that more than 11,500 home batteries were installed in just the first few weeks, with installation rates pushing above 1,000 systems per day at one stage. Commentators compared the surge to the original rooftop solar boom.
By late September 2025, the Clean Energy Regulator reported more than 55,000 applications to the program, putting the total installed storage on track to rival some of Australia’s biggest grid-scale batteries within months.
By October 2025, industry analysis estimated the program had helped drive over 100,000 battery installations, totalling around 2 GWh of distributed energy storage, increasing Australia’s installed home battery capacity by more than 50 percent in under four months.
Where is uptake strongest?
Some states are leaning into the rebate more heavily than others.
In South Australia, for example, government and industry figures have pointed out that the state has roughly 7 percent of Australia’s population but around 16 percent of batteries installed under the federal scheme so far. That makes SA one of the early leaders in battery adoption.
In New South Wales, the combination of federal discounts plus the NSW VPP incentive (offering up to around $1,500 to connect your battery to a VPP) has created a strong pull for households who already have rooftop solar and want to take the next step toward energy independence.
Why is demand so strong?
A few big factors are driving the popularity of the rebate:
- Improved economics
Independent analysis shows that, with the 30 percent federal discount plus state-based VPP incentives, many batteries now have realistic payback times in the 2–6 year range, particularly for households with high evening usage. Consumer advocacy and finance articles have highlighted examples of larger batteries virtually eliminating power bills for some households once the rebate is applied.
- Rising energy prices and energy independence
With wholesale price volatility and retail tariffs rising over the past few years, more households are using batteries to protect themselves against bill shocks and outages. Batteries let them store excess solar during the day and use it at night, instead of relying on the grid during peak times.
- Bigger systems than before
Reports on early program data show the average battery size installed under the new scheme is significantly larger than pre-rebate installations, often around 17 kWh or more.
That suggests households aren’t just dipping a toe in; they’re investing in full-featured systems designed to cover a big chunk of their evening and overnight use.
- Rooftop solar is already everywhere
With over 3–4 million Australian homes already having rooftop solar, the battery rebate landed in a market where many people have "been waiting for the numbers to stack up". The rebate, plus VPP incentives, is the tipping point for a lot of those households.
Will the rebate funding really last until 2030?
On paper, the Cheaper Home Batteries Program is scheduled to run until 2030, with the value of the discount stepping down a little each year. Additional funding has also been earmarked beyond the original announcement, but yet to be confirmed.
However, multiple independent analyses suggest that, at current uptake:
- The original $2.3 billion pool is likely to be exhausted well before 2030 if demand continues at current rate.
- Follow-up analysis from SolarQuotes and financial press reporting indicates that even with additional allocations, the combined funding may still fall short if installation rates stay this high.
Some commentators have warned the program could hit a funding wall by mid-2026 to 2028, depending on how quickly Australians keep installing batteries. There is also an open question about whether future governments will top up the scheme or let it taper out earlier than originally planned.
How does NSW’s VPP incentive tie into the boom?
In NSW, the Peak Demand Reduction Scheme (PDRS) was updated from July 2025 to increase the upfront incentive for registering a battery with a Virtual Power Plant. This change was explicitly framed as building on the success of the federal battery rebate and encouraging households to share their stored energy with the grid during peak times.
Under this setup:
- The federal rebate reduces the upfront cost of the battery itself.
- The NSW VPP incentive pays you to connect that battery to a VPP contract.
- The VPP operator then pays ongoing credits or bill reductions when your battery is used to support the grid.
This stacking of incentives is a big reason NSW appears so prominently in early battery uptake statistics.
Should you get in now while the rebate is strong?
With demand at record levels and early data showing just how quickly Australians are taking up the rebate, it makes sense to take advantage of the support while it’s at its highest.
A few key points for homeowners:
- The rebate steps down each year, so the strongest incentives are available right now, in the early phase of the program.
- Funding is substantial but not unlimited, and several independent analyses suggest the current surge could bring forward the tapering of support.
- Installer schedules are already booking out months ahead in many regions, meaning those who act earlier often secure better installation timeframes and rebate availability.
If you’ve been considering solar battery storage, especially if you already have a rooftop system, this is one of the most favourable periods Australia has ever had for battery installation. Getting an assessment now means you can lock in higher rebate value and avoid potential waiting lists as demand continues to rise.
What this means for SunPeople customers
For SunPeople customers in NSW, the current environment is unusually favourable:
- Federal battery discounts can cut around 30 percent off upfront costs.
- The NSW VPP incentive can provide an additional upfront payment for eligible, VPP-connected systems.
- Strong early uptake and solid safety standards mean the technology is maturing quickly, with more choice in battery brands and capacities than ever before.
The flip side is that this level of popularity won’t last forever at the same support level, both rebate size and program funding are expected to reduce over time.
If you’re curious whether a battery makes financial sense for your home, the best next step is a tailored energy assessment: looking at your actual bills, solar system, night-time usage, and whether a VPP connection fits your comfort level.
Final Thoughts
The new battery rebate hasn’t just been “popular”, it’s fundamentally reshaping how Australian homes use energy. With over 100,000 installations and counting, and billions in funding being rapidly taken up, the Cheaper Home Batteries Program is accelerating a second wave of the clean energy transition: from generating solar to storing it.
For homeowners, it’s a rare moment where policy, technology and household economics are all pointing in the same direction. The key is making a smart, informed decision while the support is still strong.
