Community batteries are helping neighbours in Australia share energy – Here’s how
As Australia moves toward a cleaner energy future, one innovative solution is emerging as a game-changer for households and the electricity grid: community batteries. These shared energy storage systems allow multiple homes to store and use excess renewable energy, providing benefits such as lower electricity costs, increased grid stability, and greater resilience during power outages.
With rising electricity prices and an increasing number of households installing rooftop solar panels, community batteries are helping Australians make the most of renewable energy while ensuring a more stable and efficient power grid.
Community batteries offer a cost-effective and efficient alternative to individual home batteries. These large, shared batteries store excess renewable energy generated by homes in a neighbourhood and distribute it when needed. This allows multiple households to access stored solar power without needing their own expensive battery system.
When homes with solar panels generate more energy than they use, the extra power is stored in the community battery instead of being sent back to the grid. When demand rises, such as in the evening, households can draw from the stored energy instead of using expensive grid electricity. The battery helps stabilize the grid by balancing supply and demand, reducing the likelihood of blackouts and ensuring a smoother transition to renewable energy.
Community batteries are better than individual batteries for several reasons. They are more affordable because shared infrastructure means lower household costs than buying and maintaining a personal battery.
They are more efficient because a single, larger battery can store and distribute energy more effectively than many smaller individual systems.
They are better for the grid because they help reduce strain on the power network, making the electricity supply more stable for everyone. And they are accessible to all. Renters and apartment residents, who may not have the ability to install solar panels or home batteries, can still benefit.
Several Australian communities are already seeing the benefits of community batteries. In Western Australia, the state government has rolled out community battery trials in suburbs like Alkimos Beach and Ellenbrook. These projects allow households to store and share excess solar power, reducing their reliance on the grid and lowering energy costs. In Alkimos Beach, residents using the community battery have seen electricity bill reductions of up to 15%.
Another success story comes from Melbourne’s Yarra Energy Foundation, which has partnered with energy provider Citipower to install a 200 kWh community battery in the inner-city suburb of Fitzroy. The battery helps store excess solar energy from nearby homes, reducing reliance on coal-fired power plants and cutting carbon emissions.
In South Australia, the government has launched a program to install solar-powered community batteries in multiple suburbs, allowing more households to benefit from renewable energy without the upfront costs of individual storage.
Community batteries provide several key advantages, making them a promising solution for Australia’s future energy. By storing solar power for later use, households rely less on expensive electricity from the grid, leading to significant savings on power bills.
Balancing supply and demand helps prevent blackouts and makes the electricity network more resilient. Storing excess solar power allows for greater reliance on clean energy, reducing the need for fossil fuels.
Shared battery projects encourage local participation, giving residents more control over their energy use and helping build a sense of community ownership.
Community batteries are emerging as a smart, scalable solution for Australia’s energy needs. They enable more households to benefit from renewable energy, lower electricity costs, and create a more stable power grid.
With government support and successful pilot programs across the country, now is the time for more communities, businesses, and policymakers to explore and invest in community battery projects. By working together, Australians can build a cleaner, more resilient, affordable energy future—one neighbourhood at a time.
