The highly anticipated federal government's "Cheaper Home Batteries" program officially launches today, July 1st, offering Back Country households an opportunity to slash their energy bills and contribute to a more stable electricity grid. The initiative offers around a 30 per cent discount on the upfront cost of installing a home battery, and is being hailed by industry experts as the most significant development in consumer energy since the widespread adoption of rooftop solar.Rewiring Australia, a leading research organisation, projects that adding a home battery to an average household with rooftop solar and all-electric appliances could lead to savings of approximately $1,000 a year."The upfront cost of batteries has been a significant hurdle for many, despite a high desire to install them," said Dr. Saul Griffith, Founder and Chief Scientist of Rewiring Australia. "This policy is a crucial step towards making this bill-saving technology accessible to more Australians."The Albanese Government's election promise to subsidise battery installations by 30 per cent will run until 2030, offering a sustained incentive for homeowners and businesses to embrace energy storage. This policy arrives after years of lobbying and consultation by industry groups like the Smart Energy Council (SEC) and Clean Energy Council (CEC)."This is not just a milestone, but the next chapter in our nation’s clean energy journey – the next phase in consumers taking control of their energy bills," stated Con Hristodoulidis, CEO General Manager for distributed energy.How it Works and What You Need to Know:The "Cheaper Home Batteries" program, delivered through the Small-scale Renewable Energy Scheme (SRES), provides an upfront discount of roughly 30 per cent on eligible small-scale battery systems, ranging from 5 kilowatt-hours (kWh) to 100 kWh. For instance, a 10 kWh battery, typically costing around $11,120, could see a rebate of approximately $3,300, reducing the net cost to $7,400. The discount is facilitated through the creation and sale of Small-scale Technology Certificates (STCs), with the 2025 rate equating to around $372 per kWh of usable capacity.Eligibility is straightforward:The rebate is not means-tested, meaning it's open to any household or business installing a solar battery.It's limited to one solar battery per household or business.The battery system (5 kWh to 100 kWh nominal capacity, with the rebate applying to the first 50 kWh of usable capacity) must be installed with a new or existing solar photovoltaic (PV) system.Batteries must be on the Clean Energy Council (CEC) approved product list and installed by a Solar Accreditation Australia (SAA) accredited installer.Crucially for grid stability, on-grid batteries must have the technical capability to participate in a Virtual Power Plant (VPP), though participation is generally optional (with some exceptions, as detailed below).The Clean Energy Regulator (CER) advises Back Country residents to research thoroughly, compare quotes, and choose an appropriately sized battery for their energy needs. Be wary of "too-good-to-be-true" offers, as the CER is keeping a close eye on compliance and sales tactics to protect consumers.The NSW Twist: Boosted Incentives for VPP ConnectionWhile the federal rebate takes over from the NSW state home battery rebate, which ceased on June 30, there's good news for those in NSW looking to maximise their savings. Under the state's Peak Demand Reduction Scheme, households connecting their solar battery to a Virtual Power Plant (VPP) can access a boosted discount.From July 1, incentives for joining a VPP will increase to up to $550 for a 10 kWh battery and up to $1,500 for a 27 kWh battery. The actual amount will depend on your chosen VPP provider and contract, including how much you get for sending solar to the grid and when the VPP can access your battery. Current VPP providers offering the NSW incentive include AGL, Amber, Engie, Globird, Origin, Powow, and Shinehub.What is a Virtual Power Plant (VPP)?VPPs are a network of aggregated and coordinated consumer energy resources, like your home battery, that can be controlled by a third party. They essentially pool stored energy from many homes to support the grid during peak demand or supply shortages. This not only helps you reduce your bills by optimising energy use, but also contributes to overall grid stability."If just two in 10 Australian homes installed batteries, the collective on-demand peak reduction output could be three times that of the country’s largest coal power station, or nearly double that of the Snowy Hydro 2.0 scheme," said Francis Vierboom, CEO of Rewiring Australia. While VPPs are still evolving, and their complexity can be a hurdle for some, the financial incentives are causing more homeowners to consider joining up. With the federal government's substantial rebate and the added incentives for VPP participation, the path to lower energy bills is becoming more affordable.
