The Government Will Pay 30% of Your Business Battery.

The federal Cheaper Home Batteries Program covers businesses, not just houses. Right now it pays $272 per kilowatt-hour toward a battery system. That rate took effect on 1 May 2026. It drops to $228 in January 2027 and keeps falling every six months after that.

The program is bigger than most business owners realise

The original program was $2.3 billion. It has since expanded to $7.2 billion through 2030. Any business with existing or new rooftop solar can add a battery between 5 and 100 kilowatt-hours, with the first 50 kWh rebated. There is no means test, no revenue cap, and community organisations qualify too.

The battery must be paired with solar PV, installed by a CEC-accredited installer, and be VPP-ready (virtual power plant capable). Most modern battery systems sold in Australia already meet that last requirement.

What this means for business energy costs

Energy is a top-three operating cost for most Australian small businesses. Quarterly bills run between $800 and $3,000 depending on the industry. For businesses on commercial tariffs with demand charges, the peaks can make up 30 to 40 per cent of the bill. A battery flattens those peaks.

Here is what the maths looks like at today's rebate rate. A 10 kWh battery costs roughly $8,650 installed. The rebate covers $2,720. You pay $5,930. A 20 kWh system runs about $14,700, with $5,440 covered by the rebate, leaving $9,260.

Some states add their own support on top of the federal rebate, and the terms differ from the federal program. Western Australia, South Australia and the ACT all run separate battery schemes with their own eligibility rules, so check what your state actually offers before you assume it stacks.

Over 20 years, commercial battery storage delivers $30,000 to $50,000 in avoided energy costs. The steepest savings go to businesses running refrigeration, air conditioning, welding equipment, or heavy machinery during peak tariff windows.

What to do

Pull your last two electricity bills and check whether you are on a demand tariff. Most commercial customers are, and most do not know it. If your bill shows a "demand charge" line item, that is the cost a battery cuts deepest. For businesses with complex tariff structures and high demand charges, the payback period can be as short as six years.

Get installer quotes now. The current rebate of $272 per kWh drops to $228 in January 2027. Installation takes 10 to 16 weeks from quote to commissioning, which means a quote today puts you at the back end of 2026, still inside the current rate window. Waiting until October or November risks slipping into the lower tier.

If you are in WA, SA, or the ACT, check what stacks on top. The state programs are separate applications with separate deadlines, and not every installer handles both.

Ask your installer about VPP enrolment. It is not automatic. Your battery feeds stored energy back into the grid during demand events and earns credits. The revenue varies by state and retailer, but it shortens the payback period and it is worth asking about before the system is commissioned.

And if you have been putting this off because you thought you needed new solar first: you do not. Existing rooftop systems qualify, as long as they are connected and the installer is CEC-accredited.
