A cheery headline from a New South Wales state government news release published yesterday glossed over a bombshell contained within. But there is good news too (for some).
“NSW & Commonwealth double incentives for batteries,” declared the headline. I’ll get to what that’s actually about in a bit; but basically it’s only referring to a boost to Virtual Power Plant (VPP) incentives, not the state’s battery rebate.
In fact, around halfway down the news item was this (bolding mine):
“The increased Virtual Power Plant incentive will replace the NSW home battery installation incentive which has been doubled by the Commonwealth program.”
The NSW Government battery rebate (in practice and name an up-front discount) can continue to be claimed for home battery installations up until Monday 30 June 2025. But note the state government has confirmed the discount cannot be combined with the upcoming federal home battery rebate, which starts on Tuesday 1 July 2025.
The NSW Government had been seeking advice to make its incentive “stackable” with the federal subsidy and address a host of other issues. Obviously, that didn’t pan out.
While technically the NSW rebate can still be claimed until July 1, it now doesn’t make much sense to use it. Those considering buying a home battery are better off taking advantage of the federal battery rebate under the Cheaper Home Batteries Program.
According to the state government, the solar battery discount was a ‘huge success’, with more than 11,400 installations since it was launched in November 2024. But the reality on the ground is the incentive has been plagued with problems.
There’s understandably disappointment and some anger among both installers and solar battery buyers with this news. We’re informed some NSW installers had written in contract clauses they would take the hit if the rebate was withdrawn. Ouch.
As for buyers who have already signed on the dotted line but are now having second thoughts, see our recent article on rebate-related quotes and deposit refunds.
NSW VPP Payment Boost
Back to the better news, for some anyway.
When the NSW solar battery discount program originally kicked off, there were also two separate payments available if also joining an eligible Virtual Power Plant (VPP) program — one after joining and another could be claimed 3 years later.
Just briefly for those not familiar with what a VPP is, a Virtual Power Plant consists of Distributed Energy Resources (DERs) such as home batteries that are virtually co-ordinated by a central operator. This gives the operator control over when batteries are charged from and discharged to the grid. The nature and intensity of that activity depends on the program.
For the participant, there is usually an incentive for allowing their battery to be controlled by a third-party. You can compare various programs and what they offer on our VPP comparison table and learn about the pros and cons of Virtual Power Plants here.
The NSW VPP incentive has been increased to up to $1,500 from 1 July 2025 to encourage more folks to get on board with VPPs — and this will be a single payment. The incentive varies according to the size (energy storage capacity) of the battery. According to an example on the NSW Government explainer page; the new incentive amounts are estimated at:
- approximately $550 for a 10-kilowatt-hour ( kWh) battery
- approximately $1,500 for a 27- kWh battery.
… so in other words, around $55 per usable kWh (but that’s yet to be confirmed). Batteries will need to be between 2-28kWh capacity to receive the incentive.
And yes, the VPP incentive will be available to those who have installed a battery under the federal battery rebate program. Other existing eligible solar battery owners can also receive it, but they’ll need to work with an Accredited Certificate Supplier (ACP) to get signed up to a VPP.
On a related note, there was also a requirement to have 6+ years of warranty on the battery. According to SolarQuotes resident fact-checker Ronald Brakels, that requirement *may* have been removed as he didn’t see it currently mentioned on the state government’s VPP incentive explainer page.
Other Recent Battery Incentive Changes In Australia
The NSW Government’s announcement comes just a few days after the Western Australian government said its Residential Battery Scheme rebate will be slashed (but stackable with the federal scheme) and VPP participation will be mandatory. But on the positive side, the WA rebate will be made available to five times as many households — up to 100,000.
The Northern Territory’s government recently announced its up-to-$12,000 battery rebate has ended due to reaching the program’s funding cap of $6 million, and Victoria wound up its solar battery loans program in late May.
