Rebates & Incentives
NSW Commercial Battery Incentives Are Now Open
Since 1 September 2026, NSW businesses can claim a Peak Demand Reduction Scheme incentive for commercial batteries. Pair the battery with new solar and the incentive is higher*. NSW sites only. Installed by an Accredited Certificate Provider.
01
A New Incentive for NSW Business Batteries
The business and commercial battery activities under the NSW Energy Security Safeguard started on 1 September 2026. The incentive is delivered through Peak Reduction Certificates, which your accredited provider creates and sells, and the value comes off the project cost.
You do not apply yourself. What you do need is the right battery, the right installer and a site in NSW.
02
Two Pathways: BESS4 and BESS5
If your site sits close to a boundary, we can model both sizes. Choosing 190kWh over 210kWh can change which activity applies.
| BESS4 | BESS5 | |
|---|---|---|
| Who it is for | Small and medium business | Commercial and industrial |
| Battery size | 20kWh to 200kWh | 200kWh to 30MWh |
| Incentive covers | The eligible battery capacity | The first 10MWh of eligible capacity |
03
Is My Business Eligible?
- Your site is connected to the NSW grid.
- The battery was installed on or after 1 September 2026.
- The installer is an Accredited Certificate Provider (ACP).
- One incentive applies per site under these activities.
The scheme rules are set by the NSW Government and administered by IPART. Read them on the NSW Energy Sustainability Schemes site, and ask us if a rule is unclear for your site.
04
Pair Your Battery With Solar for a Higher Incentive
Solar is not mandatory, but pairing the battery with new qualifying solar earns a higher incentive rate*. It also gives the battery something to charge from, so your bill falls further.
Our commercial solar and battery design covers both parts as one project, with one set of paperwork.
05
Combine It With the Federal Battery Program
The NSW incentive can generally be combined with the federal Cheaper Home Batteries Program*. Federal rules differ by battery size, and the program tiers its discount, so we model both for your site. You can read the federal rules on the Clean Energy Regulator site.
Our rebates and incentives guide shows how state and federal programs fit together. Subject to eligibility and assessment.
06
What Size Battery Suits a Business?
The right size depends on your interval data, your tariff and what you need to keep running. A battery sized to your demand peaks often does more than a bigger one. Many small businesses land between 30 and 50kWh. Our 40kWh battery and 50kWh battery pages show how the federal rebate treats those sizes. For help planning the rest of the site, see commercial energy management.
07
What We Need From You
- Twelve months of interval data, or your last few bills
- The site address and, if you have it, the meter number
- A photo of the switchboard and the proposed battery location
- Whether you plan new solar, and roof details if so
- Your preferred timing
08
From Enquiry to Install
- Enquiry. You send the details above.
- Assessment. We review your data, site and eligibility.
- Proposal. Battery size, assumptions and the incentive in writing.
- Approval. We prepare the network application and scheme paperwork.
- Install and commissioning. Accredited installers complete and test the system.
Equipment
Battery Brands We Install
We fit storage from manufacturers with local support teams, so the warranty on your battery still means something in ten years.
Brand availability depends on your system design and location. We confirm the selected equipment and manufacturer warranty in your written quote.
Important Information
Incentive values are indicative and depend on your site, battery size and the current Peak Reduction Certificate price, confirmed by an accredited assessment. The NSW Peak Demand Reduction Scheme applies to eligible NSW sites only. Frostac is not a financial adviser. Scheme details are from the NSW Government and IPART, correct at the time of publishing.
* Incentives, savings and payback are indicative, depend on your site, tariff, products, scheme rules and the installer's accreditation, and are not guaranteed. Your written proposal prevails. See clauses 24.1, 24.3, 24.6 and 24.7 of the Terms and Conditions.
Questions
Common Questions
01When Did the NSW Business Battery Incentives Start?
The business and commercial battery activities started on 1 September 2026, so they are open now.
02How Much Can My Business Get?
The value depends on battery size, location, whether solar is paired, and the market price of Peak Reduction Certificates. We calculate a figure for your site and write down the assumptions. We do not promise a number.
03Do I Need Solar to Qualify?
No. Solar is not required. Pairing the battery with new qualifying solar earns a higher incentive.
04Can I Combine This With the Federal Rebate?
Generally yes. The federal program has its own size limits and rules, so we model both together.
05What Battery Size Makes Sense for My Site?
It depends on your demand pattern. We size from 12 months of interval data, not a rule of thumb.
06Does the Incentive Apply Outside NSW?
No. It applies only to eligible NSW sites.
