Certificate & Rebate Handling
We coordinate directly with the Accredited Certificate Provider to generate and assign your Peak Reduction Certificates, so your NSW commercial battery rebate discount is applied upfront — no chasing paperwork after install.
PDRS-Compliant Installation
Every battery we install is scoped to meet NSW commercial battery rebate requirements — right sizing, right network tier, right paperwork — so your Peak Reduction Certificates aren't put at risk by a non-compliant setup.
Stronger Sustainability Profile
Reduce reliance on grid power during high-demand periods and lower your site's carbon footprint — useful for ESG reporting and sustainability commitments.
The NSW commercial battery rebate (the Peak Demand Reduction Scheme) puts real money on the table for businesses, strata blocks and commercial sites that install a battery to shave the evening peak. A 100 kWh business battery can bank around 8,000 certificates — that’s roughly $21,000–$29,500 knocked off the price upfront. The business tiers (BESS3–BESS5) open on 1 September 2026.
NSW is basically paying businesses to hang a battery on the wall. And no, this isn’t one of those rebates you apply for and then wait months to see — it’s a straight-up discount applied before you even pay the invoice. Most business owners we speak to haven’t heard of it at all, and the few who have usually assume it’s a homeowner-only thing. It’s not. Come September 2026, the real money in this scheme is aimed at businesses, strata committees and commercial properties.
A 100 kWh battery on a NSW business site earns somewhere around 8,000 certificates, worth roughly $21,000 to $29,500 off the install — and that’s before you even talk finance. Bigger sites earn a lot more than that. Here’s the full breakdown: who qualifies, what it’s worth, and how you can work out your own number in about half a minute.
So what actually is the NSW commercial battery rebate?
The NSW commercial battery rebate is officially called the Peak Demand Reduction Scheme, or PDRS. It’s run by IPART under the NSW Government’s Energy Security Safeguard, and the logic behind it is pretty straightforward: the grid gets hammered hardest between 2:30pm and 8:30pm, so the scheme rewards anyone who installs gear that takes load off during that window. A battery that soaks up solar during the day and then discharges through that evening crunch is exactly what they’re after.
Install one, and the scheme issues you Peak Reduction Certificates (PRCs). An Accredited Certificate Provider then buys those off you and passes the value straight back as a discount on your system — before you sign anything. No waiting around, no claiming money back later, no government paperwork to chase. It’s just built into the price.
How much is the NSW commercial battery rebate worth?
Three things drive the number: how big the battery is, how hard it’s working during the peak window, and whether you’re pairing it with new solar. As a rough guide on the Ausgrid network with new solar, at today’s certificate prices:
- 60 kWh strata/apartment battery: around 6,065 certificates — roughly $15,000–$21,000 off
- 100 kWh small-medium business battery: around 8,424 certificates — roughly $21,000–$29,500 off
- 250 kWh commercial battery: around 21,060 certificates — roughly $52,600–$73,700 off
These are estimates, not fixed numbers — certificate prices move with the market, which is why we lock in your actual figure in the written quote. But the trend holds either way: the bigger the site and the harder the battery works, the more the scheme pays out. If you want to skip the guesswork, our PDRS rebate calculator runs the scheme’s own numbers against your battery size and network so you’ve got a figure before you even talk to us.
Who qualifies for the NSW commercial battery rebate — BESS3, BESS4, BESS5?
The NSW commercial battery rebate is split into three tiers based on the type of site:
- BESS3 (apartments/strata): buildings with four or more dwellings, batteries sized 20–200 kWh, one shared battery with the savings spread across the block.
- BESS4 (small/medium business): shops, warehouses, offices, workshops — 20–200 kWh, paired with new solar. Not for homes, not for data centres.
- BESS5 (commercial/industrial): bigger sites, from 200 kWh right up to 30 MWh.
Homes and micro-businesses fall under a separate tier, BESS1, covering 2–28 kWh, which has actually been running since 1 July 2026.
Worth flagging early: the commercial tiers (BESS3, BESS4, BESS5) are for registered businesses only — you’ll need an active ABN. The same goes for the finance and tax side of things. We check your eligibility before you commit to anything.
When does the NSW commercial battery rebate start?
The business, strata and commercial tiers of the NSW commercial battery rebate — BESS3, BESS4 and BESS5 — start on 1 September 2026. The scheme’s peak-demand target has already been wound back once, and certificate prices tend to run highest early on, so the sites that get their design and scoping sorted now will be first in line to install and cash in once it opens. Holding off doesn’t make the rebate any bigger — it just means paying full price through more peak periods in the meantime.
Do I need solar to claim the NSW commercial battery rebate?
For the business tiers, yes. BESS4 and BESS5 both require new solar sized at least a quarter of the battery’s usable capacity, installed within 90 days, plus a minimum $5,000 contribution from you. Getting the battery in within that 90-day window also unlocks the higher certificate rate — miss it, and you’re looking at roughly half the certificates. Strata and residential sites have a bit more flexibility around this. We’ll map out exactly what your site needs when we scope the job, so nothing gets missed.
Can I combine the NSW commercial battery rebate with the federal rebate?
Yes, and honestly you should. The NSW commercial battery rebate and the federal Cheaper Home Batteries Program are entirely separate schemes, so eligible systems can use both at once. The federal rebate comes off the price first, then the PDRS certificate value stacks on top of that. That’s two discounts before finance even enters the picture. The federal rebate is also due to step down again in 2027, so right now is about as good as it gets.
Who handles the NSW commercial battery rebate paperwork?
This is the bit most business owners want no part of. We handle it. Aus Energy Store designs and installs the system, then coordinates with the Accredited Certificate Provider to create and assign your Peak Reduction Certificates — so the discount lands upfront and you never have to touch a certificate registry yourself. We’re CEC-accredited from the first panel to final commissioning; the certificate provider deals with the trading side, we deal with the build.
End result: one quote, one net price, one payback figure, and one team that owns the whole process.
It’s the Peak Demand Reduction Scheme (PDRS), a NSW Government program under the Energy Security Safeguard. Install a battery that cuts demand during the 2:30–8:30pm peak, and you earn Peak Reduction Certificates, which an Accredited Certificate Provider buys and returns to you as an upfront discount.
It comes down to battery size, network, and whether new solar is included. As a guide on Ausgrid with new solar, a 100 kWh business battery earns around 8,000 certificates — roughly $21,000–$29,500 off — while a 250 kWh commercial battery can be worth $52,600–$73,700. The exact value is market-driven and confirmed at quote stage.
Home and small-business batteries (BESS1) opened 1 July 2026. The apartment, small-medium business, and commercial/industrial tiers (BESS3, BESS4, BESS5) start 1 September 2026.
For the business tiers (BESS4, BESS5), yes — new solar sized at a quarter of the battery’s usable capacity, installed within 90 days, plus a $5,000 minimum contribution. Installing within that 90-day window also gets you the higher certificate rate. Strata and residential rules are more relaxed.
Aus Energy Store does. We design and install the system and coordinate with the Accredited Certificate Provider to create and assign your certificates — so you get the discount upfront rather than claiming it back later. eHomes is your installer, not the scheme regulator or certificate provider.
Yes. The NSW PDRS discount and the federal Cheaper Home Batteries Program are separate, so eligible systems can use both — federal comes off first, then the PDRS certificate value on top.
