Rising electricity prices have prompted Australian homeowners to search for ways to reduce their energy bills and achieve energy independence. With the average Australian household using 18.71 kWh per day and facing quarterly electricity bills of $300-$500, the financial pressure is real.
With the federal government's new Cheaper Home Batteries Program launching July 1, 2025, combined with innovative green loans and sustainable energy finance options, installing a home battery system has never been more accessible. This comprehensive guide explains how to combine government battery rebates with green loan financing to make your energy storage investment both affordable and profitable. Looking for finance, get started here!
The financial case for batteries has fundamentally changed. Government analysis shows households can save $700-$1,600 per year on electricity bills, with potential savings of up to 90% of typical electricity costs when batteries are combined with solar systems.
Understanding the Federal Battery Rebate Program
Current Rebate Amounts and Timeline
The $2.3 billion Cheaper Home Batteries Program will support Australian households and small businesses with a discount on the cost of installing small-scale battery systems. From 1 July 2025, the program will provide around a 30% discount on the upfront cost of installing eligible small-scale battery systems.
2025 Rebate Value: $372 per kilowatt-hour of a battery's usable capacity. After administrative fees, the actual battery price reduction is likely to be around $330 per usable kWh
Example: For a popular 10kWh battery system, you'll receive approximately $3,300 in rebates, reducing a typical $12,000 system to around $8,700.
