TL;DR
- 1 May 2026 (federal): the Cheaper Home Batteries Program discount now shrinks every six months instead of once a year, and it is scaled by battery size. You get the full rate on the first 14 kWh, 60% of it between 14 and 28 kWh, and 15% between 28 and 50 kWh.
- 1 July 2026 (NSW): a new Peak Demand Reduction Scheme Rule started. The NSW battery installation incentive came back for government owned or managed property and Minister-approved exempt energy programs, but not for ordinary households. The Virtual Power Plant incentive became much easier to qualify for.
- 1 September 2026 (NSW): three new incentives start, for apartment buildings, small and medium businesses, and large commercial and industrial sites.
- Still not available: the vehicle-to-grid incentive is written into the Rule but has no start date.
The short version: what a NSW household can actually get right now
If you are a homeowner in NSW putting a battery on an ordinary house, the honest answer is that your discount is federal, not state. NSW DCCEEW says so plainly on its own Install a Battery page: the NSW battery installation discount is no longer available for home and business owners, and the Australian Government’s Cheaper Home Batteries Program discount is the one now available.
There is still a NSW-side incentive, but it pays for something different. It rewards connecting a battery you already own to a Virtual Power Plant, not buying the battery in the first place. That distinction runs through everything below, so it is worth holding onto: the federal scheme helps you buy a battery, and the NSW scheme mostly pays you for what your battery does once it is installed.
The three incentives starting on 1 September are the exception. They do help pay for the battery itself, but only for apartment buildings, businesses and industrial sites. An ordinary house is the gap.
1 May 2026: the federal battery discount got smaller, and now shrinks twice a year
The Cheaper Home Batteries Program works through small-scale technology certificates. Your installer creates them against your installation and passes the value through as a discount on your invoice. You do not apply for anything and no government agency sends you money.
Two things changed on 1 May 2026.
First, the STC Factor that sets how many certificates an installation generates now declines every six months rather than annually, and at a higher rate than before. The schedule runs down to 2030.
Second, the factor is now applied on a tapering basis by capacity band:
| Usable capacity | Share of the STC Factor applied |
|---|---|
| First 14 kWh | 100% |
| Above 14 kWh, up to 28 kWh | 60% |
| Above 28 kWh, up to 50 kWh | 15% |
The practical effect is that the first 14 kWh of a battery attracts far more support than the last 14 kWh. Above 50 kWh of usable capacity, no further certificates are created at all. If you were sizing a battery on the assumption that a bigger system earns proportionally more, that stopped being true in May.
See our guide to how much battery rebates will drop after May 2026 for exactly how much this reduces your discount over time.
Our guide to the 1 May 2026 federal battery rebate changes covers the federal side in full.
For system sizing under the new tapering rules, our guide to best battery size for rebates in 2026 works through it.
1 July 2026: the NSW rules were rewritten
On 1 July 2026, a new Peak Demand Reduction Scheme Rule took effect. Two changes matter to anyone shopping for a battery.
First, a word on how the NSW side pays, because it is not a cheque. Every NSW incentive below works through Peak Reduction Certificates. One certificate represents 0.1 kilowatts of capacity to reduce demand during the peak window, which runs from 2:30pm to 8:30pm AEST daily between 1 November and 31 March. You are the original holder of the certificates your installation creates, and you nominate an Accredited Certificate Provider to create and sell them. The value comes back to you as a discount on your invoice, not as a government payment.
The NSW battery installation incentive came back, but not for households
BESS1, the NSW battery installation incentive, came back on 1 July 2026, but only for narrow categories: installations on government owned or managed property, and households reached through a Minister-approved exempt energy program. NSW had suspended BESS1 from 1 July 2025, because the federal Cheaper Home Batteries Program had arrived and the two could not be combined; the July 2026 rule change lifted that suspension only for those two categories, and only for installations dated on or after 1 July 2026. In those cases, and only those, the NSW incentive can be stacked with the federal discount.
If you own an ordinary house in NSW, this change does not reach you. It is not an application you can make.
Our NSW battery rebate hub lays out how BESS1 through BESS5 compare side by side, including which one actually applies to your situation.
The VPP incentive got easier to qualify for
BESS2 is the NSW activity that pays for connecting an existing battery to a Virtual Power Plant, so the battery can discharge into the grid when demand peaks. Four things changed on 1 July 2026:
- The eligibility threshold rose from 28 kWh to 50 kWh of usable capacity. The incentive itself is still capped at 28 kWh, so a larger battery qualifies but does not earn more.
- The requirement to have solar installed at the site was removed. A battery on its own can now qualify.
- The battery warranty requirements covering normal use conditions were removed. A battery still needs at least 6 years of warranty remaining.
- The nomination form can now be signed up to 90 days after onboarding is complete, provided it is signed before certificates are created.
Dropping the solar requirement is the significant one. It opens BESS2 to a group of households who previously could not access any NSW battery incentive at all.
The gates that remain are worth knowing before you plan around it. The site has to be a Class 1 building or a small business site, which means apartment buildings do not qualify for BESS2. There must be an existing battery at the meter, between 2 kWh and 50 kWh of usable capacity, and no life support equipment at the address. The account holder has to sign a contract with the aggregator to provide demand response capacity for at least 12 months. And it can be claimed once per meter, permanently: once certificates have been created for that activity at a National Metering Identifier, no further ones can be created there.
Full detail is in our guide to the Virtual Power Plant NSW rebate guide.
1 September 2026: three new incentives start
The new Rule staged three battery activities to start on 1 September 2026, and none of them is for a standard house.
Three new NSW battery incentives start on 1 September 2026, and none of them is available before that date. BESS3 supports a shared battery in an apartment building of at least four dwellings, for usable capacity above 20 kWh up to 200 kWh, with a minimum customer payment of $1,000 excluding GST. BESS4 covers small and medium business sites at the same capacity range, with a higher minimum payment of $5,000 excluding GST, claimable once per site. BESS5 covers larger commercial and industrial sites, from above 200 kWh up to 30,000 kWh eligible capacity, with equipment tested to the UL9540A thermal runaway standard and no minimum customer payment. None of the three is available to an ordinary house.
Apartment buildings (BESS3)
A Class 2 apartment building with at least four dwellings and no existing battery on site is what BESS3 is built for. Its usable capacity range is above 20 kWh to 200 kWh, and cannot exceed six times the battery inverter’s output.
Two conditions catch people out. The battery must be installed outdoors, which rules out most basement car parks. And certificates can only be created where the building has paid a net amount of at least $1,000 excluding GST for each item of equipment. That payment cannot be reimbursed, discounted back, or offset with anything in kind.
Townhouses and villas are expressly excluded. The activity is written for Class 2 buildings.
The NSW battery rebate for apartment buildings guide covers this in full detail.
Small and medium business (BESS4)
Business sites that are not residential buildings and not data centres are BESS4’s territory, at the same capacity range as BESS3: above 20 kWh to 200 kWh usable.
BESS4 differs from the apartment activity in two ways that matter. The minimum customer payment is $5,000 excluding GST per item of equipment, not $1,000. And BESS4 may only be conducted once per site, and not at a site where BESS5 has already been conducted.
See our NSW business battery rebate guide for the full detail.
Large commercial and industrial (BESS5)
BESS5 starts where BESS4 stops. Eligible usable capacity runs from above 200 kWh to 30,000 kWh, although the capacity the incentive is actually calculated on is the lesser of usable capacity, 10,000 kWh, and four hours multiplied by the battery inverter’s output.
Equipment must be tested in accordance with UL9540A, the thermal runaway test method. Unlike BESS3 and BESS4, the Rule sets no minimum customer payment for BESS5.
Our NSW large-scale battery incentive guide goes through the full detail.
Can you combine the NSW and federal battery incentives?
Whether a NSW battery incentive can combine with the federal Cheaper Home Batteries Program discount depends on which activity you mean, and the answer runs in different directions depending on the activity. Our NSW battery rebate hub has the full activity-by-activity stacking table and keeps it current as the PDRS Rule changes.
What has not changed, and what is not coming yet
A vehicle-to-grid activity, V2G1, has been written into the NSW Rule. It has not started, and it does not start on 1 September with the others. It begins only on a date the Minister nominates by notice published in the Gazette, and no date has been set.
The Rule ties that decision to conditions that are not yet met across the market: clear vehicle manufacturer warranty support for exporting from the car, compliance with interoperability standards including ISO 15118-20, OCPP 2.1 and AS/NZS 4777, and wider availability of bidirectional vehicles and chargers.
If you are being sold a vehicle-to-grid setup on the basis of a NSW incentive, there is no incentive to claim and no announced date for one.
Separately, the Empowering Homes interest-free loan is sometimes still quoted online. It ran as a pilot only, from February 2020 to July 2022, and does not appear among the NSW Government’s current energy supports. No NSW primary source describes a program that replaced it. Home Energy Saver is a separate, current NSW loan pathway.
Which incentive applies to you
The right activity depends on your building type, your battery’s capacity, and your installation date. The NSW battery rebate hub mentioned above has the full eligibility router covering all five activities.
What to do before 1 September
For an apartment building or a business site, the useful work happens before the start date rather than on it.
- Check the capacity gate first. Both BESS3 and BESS4 need more than 20 kWh of usable capacity, and the Scheme derives usable capacity as 90% of the nominal capacity recorded on the approved product list. A battery sold as 20 kWh will not clear the threshold on either reading of that number.
- Check where the battery can physically go. For an apartment building it has to be outdoors, and that is the condition that most often stops a project.
- Get planning and network approvals moving. Meeting the scheme’s rules does not substitute for either.
- Budget for the minimum payment. $1,000 excluding GST per item for an apartment building, $5,000 for a business site. It cannot be given back to you in any form.
- Do not sign anything dated before 1 September expecting these activities to apply to it.
FAQs
Is there still a NSW battery rebate for my house?
Not for buying the battery. NSW no longer offers a battery installation incentive to ordinary households, and its own department says so. Your upfront discount comes from the federal Cheaper Home Batteries Program. If you already have a battery, the NSW side pays you to connect it to a Virtual Power Plant under BESS2.
Can I claim both the NSW and federal incentives?
It depends entirely on which NSW activity you are claiming. VPP onboarding can be combined with the federal discount, and NSW says so expressly. Apartment and business battery installations can be combined for batteries under 100 kWh of nominal capacity, not the same figure as the usable-capacity ranges used for the NSW eligibility gates above. The household battery installation incentive cannot be combined at all outside the government and exempt-program carve-outs. Anyone who answers this question without asking which activity you mean is guessing.
When do the apartment and business incentives start?
1 September 2026. They are not available before that date, so an installation completed in August cannot claim them.
Is the NSW vehicle-to-grid incentive available?
No. V2G1 exists in the Rule but has not started, and it begins only when the Minister publishes a notice in the Gazette. No date has been announced.
What happened to the Empowering Homes loan?
It ran as a pilot from February 2020 to July 2022 and was never rolled out more widely. It is not among the NSW Government’s current energy programs, and no primary source names anything that replaced it. Home Energy Saver is a separate, current NSW loan and discount pathway for household energy upgrades.
Working out which one applies to your building or site
The activity that fits you is decided by building class, capacity and timing, and those three interact. We can work through your site’s eligibility and what it would take to meet the gates, whether that is an apartment building, a business site or a home with a battery already installed.
