From 1 September 2026, eligible NSW businesses can access new BESS4 and BESS5 incentives for commercial battery storage through the Peak Demand Reduction Scheme.
"Your business has its own energy demands. Your battery system should reflect them."
Solar Junction helps Australian businesses assess, design and install commercial energy systems around their site, electricity use and operating requirements. With new NSW battery incentives commencing on 1 September 2026, eligible businesses can now explore whether BESS4 or BESS5 may fit their project.
Three straightforward packages — whichever stage your business is at, there's a system sized around your energy usage and budget.
For businesses wanting to cut daytime energy costs with a commercial-grade solar array.
Full energy independence — generate, store and use your own power around the clock.
For businesses with existing solar wanting storage, backup and better self-consumption.
From 1 September 2026, eligible NSW businesses can access new battery incentives through the Peak Demand Reduction Scheme. BESS4 covers systems above 20kWh up to 200kWh, while BESS5 covers larger systems above 200kWh.
Eligibility and certificate outcomes depend on the applicable scheme requirements, system design and project circumstances.
