Sydney, NSW – New South Wales businesses are set to benefit from significant financial incentives for commercial battery storage, with the state government’s Peak Demand Reduction Scheme (PDRS) expanding its eligibility criteria from September 1, 2026. This policy update aims to accelerate the uptake of commercial-scale batteries, offering potential savings of up to $65,800 for eligible installations.

The expansion, announced on July 30, 2026, introduces two new activities, BESS4 and BESS5, designed to cover a substantial portion of the upfront cost for batteries ranging from 20 kilowatt-hours (kWh) up to 30 megawatt-hours (MWh). This marks a strategic shift to bolster grid stability and empower businesses to manage their energy consumption more effectively, reducing reliance on the grid during peak demand periods.

Significant Savings for Commercial Battery Projects

The PDRS operates by awarding Peak Reduction Certificates (PRCs), which hold a market value. As of June 2026, the price per PRC was approximately $3.50. NSW Government modelling indicates that a 200 kWh commercial battery installation could yield around $44,100 in incentives. For businesses integrating new solar PV alongside their battery, the benefits are even greater, with a 200 kWh battery paired with 100 kW of new solar potentially attracting approximately $65,800 in value.

These incentives are particularly impactful for larger installations, with a 5 MWh system alone potentially generating around $1,103,000 in value, increasing to approximately $1,646,000 when combined with 2.5 MW of new solar. The scheme’s extension to commercial batteries reflects a recognition of the ‘missing middle’ in Australia’s clean energy transition, where large-scale projects and residential solar have seen strong support, but mid-scale commercial and industrial solutions have lagged.

“Unblocking investment in commercial and industrial solar and batteries would benefit every energy consumer, not just the businesses installing them.” — Stephanie Bashir, CEO of Nexa Advisory

How the Expanded PDRS Works

From September 1, 2026, the PDRS will support commercial battery installations through two new activities:

  • BESS4: For small and medium business sites with usable battery capacity greater than 20 kWh and up to 200 kWh.
  • BESS5: For commercial and industrial sites with usable battery capacity greater than 200 kWh and up to 30 MWh.

To be eligible, batteries and inverters must be listed with the Clean Energy Council (CEC). For BESS4, the battery duration must not exceed 6 hours. While battery-only installations are eligible, a higher incentive applies when new solar PV is installed, requiring a solar (kW) to battery (kWh) ratio of more than 1 to 4. The PDRS does not directly incentivise the solar component itself, but rather the combined benefit of solar and storage.

Stacking Incentives for Greater Savings

A key advantage for businesses is the ability to stack this NSW PDRS incentive with the existing federal government’s Cheaper Home Batteries Program. The federal scheme offers an upfront discount of around 30% on eligible small-scale battery systems (5 kWh to 100 kWh) connected to new or existing solar PV. For batteries under 200 kWh, the federal rebate provides small-scale technology certificates (STCs) on the first 50 kWh of usable capacity, with a tiered structure: 100% for the first 14 kWh, 60% for capacity between 14-28 kWh, and 15% for capacity between 28-50 kWh.

This means that NSW businesses can potentially leverage both state and federal support to significantly reduce the capital outlay for their energy storage solutions.

Driving Energy Independence and Grid Stability

The expansion of the PDRS to commercial batteries is expected to drive greater energy independence for businesses, allowing them to store excess solar energy generated during the day and use it during evening peaks or periods of high electricity prices. This not only reduces operational costs but also lessens the strain on the grid, contributing to overall energy system reliability. The ability to retrofit solar batteries is increasingly becoming a cost-effective strategy for businesses with existing solar arrays.

The move complements broader efforts to integrate more renewable energy into Australia’s grid. Recent data shows that renewables met over 50% of the National Electricity Market (NEM) generation for the first time in the December 2025 quarter, with battery storage dominating the technology mix in FY26. By incentivising commercial battery adoption, NSW is aiming to further accelerate this transition, ensuring businesses play a crucial role in building a more resilient and sustainable energy future.

What Businesses Need to Do

Businesses considering a commercial battery installation should consult with accredited installers who are familiar with the PDRS and the federal Cheaper Home Batteries Program. Understanding the specific eligibility criteria, the calculation of PRCs, and the optimal system sizing to maximise incentives will be crucial. With the new incentives commencing on September 1, 2026, now is the time for NSW businesses to evaluate their energy needs and explore the financial benefits of commercial battery storage.
