Grid Connected Home Batteries in New South Wales, Australia

New South Wales is steadily increasing its adoption of home battery storage, with 14,064 systems now installed across the state. Together, these systems deliver 93,060 kW of power capacity and 174,887 kWh of storage capacity, enabling households to store renewable energy for when it's needed most. While only 0.4% of dwellings currently use batteries, the growth trend highlights the state's move towards smarter, more resilient energy solutions. The average home battery system in NSW provides 6.62 kW of power and 12.44 kWh of storage, giving households the ability to capture surplus solar energy generated during the day and use it in the evening or during peak demand. This helps reduce reliance on the grid, lower electricity bills, and provide backup power in the event of outages.

Battery adoption is strongly linked to the state's widespread use of rooftop solar. With 31.6% of dwellings in NSW already equipped with solar panels — representing more than 1,054,934 systems and 7,168 MW of capacity — batteries are becoming the logical next step for homeowners wanting to maximise their renewable energy use. From Sydney's metropolitan areas to regional towns and rural communities, battery storage is transforming how New South Wales residents manage their energy. As battery technology becomes more affordable and incentives expand, adoption is expected to grow rapidly, further strengthening household energy independence and contributing to a cleaner, more sustainable grid.
