Experts are anticipating a significant rise in off-grid battery storage in suburban homes as families grapple with rising living costs and energy challenges. With over 40 percent of Australian households already equipped with solar power, the next frontier in the battle for cost of living and achieving net-zero emissions is private battery storage. The Clean Energy Council has reported a steady increase in the adoption of home battery systems, with nearly 30,000 units sold in the first half of last year alone. These batteries are seen as a crucial component in Australia’s plan to reach net-zero emissions, as they are projected to make up around 50 percent of the country’s renewable energy mix, according to the Australian Energy Market Operator’s Integrated System Plan. To encourage further uptake, the Clean Energy Council is calling for government rebates of up to $6,500 for private batteries, similar to the incentives provided for solar power. The upfront cost of home battery systems, which can reach up to $15,000, has been a major barrier for households. However, with the proposed Home Battery Saver Program, payback periods for these systems could decrease by 36 percent by 2030. This could lead to an additional 410,000 batteries installed and $190 million in net savings for the energy system. The demand for home batteries is expected to surge in the next 12 months, with some providers anticipating an eight-fold increase in installations. Homeowners are increasingly opting for multiple batteries to maximize their solar power usage and reduce reliance on the grid. The installation of home batteries not only helps families save on energy costs but also adds value to their homes. A landmark trial involving the CSIRO, ING, the Australian Government, and Efficient Living aims to integrate sustainability into property valuations through a Nationwide House Energy Rating Scheme. Energy-efficient homes, particularly those equipped with solar and home battery systems, are more likely to attract buyers and can command up to 5 percent higher prices due to significant electricity savings. The installation of batteries can also double the amount of self-generated solar electricity consumed by households. As battery technology becomes more affordable and the value of selling solar power back to the grid decreases, the adoption of residential batteries is expected to increase globally by 25 percent annually over the next five years.
