Electricity costs can be unpredictable for NSW businesses. Solar reduces daytime grid purchases, but without storage, surplus generation may be exported while the business still buys electricity during expensive periods.
From 1 September 2026, eligible NSW businesses can receive an upfront discount on a new commercial battery through the Peak Demand Reduction Scheme (PDRS).
Quick answer: Eligible behind-the-meter batteries with more than 20 kWh and up to 200 kWh of usable capacity may qualify. The benefit is commonly called a rebate, but it is technically a certificate-based incentive usually applied as an upfront discount in the project quote.

NSW commercial battery rebate at a glance
| Key point | Current position |
|---|---|
| Start date | 1 September 2026 |
| Battery size | More than 20 kWh and up to 200 kWh usable capacity |
| Eligible sites | Qualifying NSW business sites, excluding residential buildings and data centres |
| Solar requirement | Solar is optional, but qualifying new or additional solar can increase the incentive |
| Indicative discount | About 20% to 30% for battery only, or 30% to 40% when qualifying solar is added |
| Minimum payment | At least $5,000 excluding GST per implementation |
How does the NSW commercial battery incentive work?
The PDRS supports equipment that can reduce or shift electricity demand during NSW summer peak periods. An eligible battery can store solar energy or lower-cost grid electricity, then supply the business when demand and electricity prices are higher.
The expected peak-demand reduction creates Peak Reduction Certificates (PRCs). A participating Accredited Certificate Provider creates and trades these certificates, with the agreed value generally passed to the business as a discount on the installation.
The discount is not a fixed government payment. Its value depends on the eligible battery capacity, inverter output, network location, system design, qualifying new solar, certificate prices and the provider’s commercial terms.
How much could the commercial battery discount be worth?
The NSW Government currently provides these indicative ranges:
- Battery without new solar: approximately 20% to 30% off the battery installation cost.
- Battery with qualifying new or additional solar: approximately 30% to 40% off the battery installation cost.
These figures are a guide, not a guaranteed quote. Equipment selection, switchboard upgrades, access, fire-safety requirements, network approvals and certificate market conditions can all change the final result.
A strong battery project should be based on total savings and operational value, not the headline discount alone. Solar Paradigm reviews electricity bills and interval data before recommending a battery size.
COMMERCIAL BATTERY ESTIMATE
Find out whether your business may qualify
Share a recent electricity bill and your site details. We can assess likely eligibility, suitable capacity and potential savings.
Who is eligible?
The main scheme requirements include:
- the battery must be installed at an eligible NSW business site connected to the electricity network
- the site cannot be a residential building or data centre
- the combined usable battery capacity must be above 20 kWh and no more than 200 kWh
- the battery must be on the approved product list and paired with a compliant inverter
- usable battery capacity cannot exceed six times the battery inverter output
- the equipment must be internet-connectable and capable of control by a Demand Response Aggregator
- the installation must be completed by appropriately licensed and accredited installers
- all electrical, safety, planning, network and evidence requirements must be met
- the customer must make a minimum net payment of $5,000 excluding GST.
Existing solar does not prevent a claim. A site with an existing battery may also qualify if a supported commercial battery implementation has not already been claimed there. Batteries commissioned before 1 September 2026 cannot receive this new discount retrospectively.
Why can adding solar increase the incentive?
Solar is not compulsory, but a higher incentive may apply when the battery is paired with qualifying new or additional solar. The new solar must generally:
- be installed within 90 days before or after the battery installation, and
- have capacity equal to at least 25% of the battery’s usable capacity.
For example, a 100 kWh usable battery would require at least 25 kW of qualifying new solar. An older solar system can continue operating, but it does not by itself satisfy the timing requirement for the higher solar-linked calculation.
Which commercial battery pathway applies?
| Feature | Business batteries 20 kWh to 200 kWh |
Larger commercial batteries Above 200 kWh |
|---|---|---|
| Usable capacity | More than 20 kWh to 200 kWh | More than 200 kWh to 30 MWh |
| Typical project | Small and medium business sites | Larger commercial and industrial sites |
| Requirements | Approved battery list and SAA-accredited battery installer | Different product, testing and installation requirements |
A system should not be held below 200 kWh simply to use the smaller-system pathway. The right capacity depends on the site’s load profile, tariff, solar production and operating needs.
How can a commercial battery reduce energy costs?
- Use more solar: store excess daytime generation instead of exporting it at a low rate.
- Reduce time-of-use costs: discharge when grid electricity is more expensive.
- Manage demand charges: reduce short grid-demand peaks caused by refrigeration, air conditioning, machinery, pumps or EV charging.
- Support essential loads: provide backup during outages when compatible switching and dedicated backup circuits are included in the design.
Correct sizing matters. Kilowatt-hours describe how much energy the battery stores, while kilowatts describe how quickly it can charge or discharge. Solar Paradigm considers both, along with bills, interval data, maximum demand, operating hours, future loads and site constraints.
How to access the NSW commercial battery discount
- Eligibility and data review: check the site, previous battery activity, bills and interval data.
- Site and system design: inspect the switchboard and battery location, then select compliant equipment and model savings.
- Approvals and installation: complete the required planning, network and scheme documentation before accredited installation and commissioning.
- Certificate processing: the participating certificate provider registers the eligible PRCs and delivers the agreed benefit, usually through the project quote.
There is no formal pre-approval that guarantees certificate creation before the work is completed. Eligibility, approved equipment and evidence should therefore be checked before signing a supply agreement.

Frequently asked questions
Is the NSW commercial battery rebate a cash payment?
No. It is a certificate-based incentive under the PDRS. The agreed certificate value is usually applied as an upfront discount by a participating provider.
What battery sizes are eligible?
The combined usable capacity must be more than 20 kWh and no more than 200 kWh for this business battery pathway.
Does the incentive require solar?
No. A battery-only project may qualify. Adding sufficient new or additional solar within the required 90-day window may produce a higher incentive.
Can a site with existing solar or a battery qualify?
Potentially. Existing solar is allowed. An existing battery does not automatically exclude the site, provided a supported commercial battery implementation has not already been claimed and all other rules are met.
Will every commercial battery provide backup power?
No. Backup requires compatible equipment, protection, switching and selected backup circuits. It must be included in the system design.
What information is needed for an initial assessment?
Start with a recent electricity bill, interval data if available, the site address, existing solar or battery details, operating hours and any planned electrical loads.
