NSW Business Battery Rebate (PDRS): What Every Business Needs to Know

The NSW Government has finally come to the table with a battery rebate for businesses: the Energy Security Safeguard scheme, published July 1, 2026.

Discover how it works, who's eligible, expected incentive values, and how much it will impact your battery payback in our detailed guide.

For many NSW businesses, battery storage has always made sense. It can reduce electricity costs, increase energy independence, improve resilience during outages and help businesses get more value from their rooftop solar.

The challenge has always been the upfront cost.

That's about to change.

From 1 September 2026, the NSW Government is expanding the Peak Demand Reduction Scheme (PDRS) to include commercial battery storage for the first time. This new incentive, delivered under the NSW Government's Energy Security Safeguard, provides eligible businesses with significant upfront financial support to install battery systems.

The incentive is delivered through two new PDRS activities:

BESS4 for battery systems between 20kWh and 200kWh

BESS5 for larger commercial and industrial battery systems between 200kWh and 30MWh

Whether you're running a retail business, manufacturing facility, warehouse, agricultural operation or commercial office, this is one of the biggest policy changes to business energy in NSW in years.

What is the NSW Business Battery Rebate? 

The NSW Business Battery Rebate isn't a separate government rebate program. It's an incentive available through the Peak Demand Reduction Scheme (PDRS), which forms part of the NSW Government's Energy Security Safeguard.

Rather than receiving a fixed rebate amount, eligible battery projects generate Peak Reduction Certificates (PRCs). These certificates have a market value and provide an upfront financial incentive that helps offset the cost of installing battery storage.

The amount you receive depends on several factors, including:

• Battery capacity

• Inverter size

• Whether new solar is installed alongside the battery

• The market value of PRCs at the time

Unlike previous battery incentives that focused primarily on households, this scheme has been specifically designed to encourage businesses to reduce electricity demand during periods when the grid is under the greatest pressure.

Understanding BESS4 and BESS5

The incentive is delivered through two separate activities that support different sizes of battery systems 

How much is the incentive worth? 

There isn't a fixed rebate amount.

The value depends on your battery size, system configuration and current certificate prices.

However, the NSW Government's own modelling shows just how significant these incentives could be.

Why has NSW introduced this incentive?

Commercial businesses consume electricity very differently to homes.

Many operate during the day, have large demand charges on their electricity bills and use equipment that creates sharp spikes in electricity consumption. Others are exposed to wholesale electricity prices or have already invested heavily in rooftop solar.

Battery storage helps businesses:

• Reduce peak demand charges
• Store excess solar energy for later use
• Shift electricity use away from expensive tariff periods
• Improve backup power and business resilience
• Participate in future demand response and energy market opportunities

The NSW Government recognised that while these benefits are significant, the upfront investment has prevented many otherwise viable projects from proceeding.

The new PDRS activities are designed to bridge that gap and encourage greater investment in commercial battery storage.

Examples from government modelling:

Who is eligible?

While every project should be assessed individually, the key eligibility requirements include:

Your business

• Must be located in NSW
• Must not be a residential building
• Must not be a data centre
• The site can only receive either a BESS4 or BESS5 incentive once

Your battery

For BESS4:

• Between 20kWh and 200kWh usable capacity
• Installed by an SAA accredited installer
• Battery and inverter must be Clean Energy Council listed
• Battery duration must not exceed six hours

For BESS5:

• Between 200kWh and 30MWh
• Battery must satisfy the required safety standards, including UL9540A testing
• Battery duration must not exceed six hours

Both activities also include requirements relating to battery sizing, inverter capacity and system configuration to ensure batteries are appropriately matched to the site.

Do I need solar?

No.

One of the strengths of the new NSW Business Battery Rebate is that solar isn't mandatory.

Many businesses already have rooftop solar. Others have limited roof space or operate facilities where batteries provide value through demand charge reduction or energy arbitrage rather than solar self-consumption.

These projects can still qualify.

However, businesses that install new solar alongside a new battery receive a higher level of incentive than battery-only projects.

If you're already planning a solar upgrade, combining both technologies may significantly improve the financial return.

Can businesses stack incentives?

Yes, in some circumstances.

Battery systems under 100kWh that qualify under BESS4 may also be eligible for the Federal Government's Cheaper Home Batteries Program.

This creates an opportunity for eligible small businesses to combine both incentives and substantially reduce the upfront investment required.

Your eligibility will depend on the specific battery system and project design.
