Australia is leading the world in rooftop solar adoption. However, not everyone can afford a home battery to store their excess energy. This is where a community battery in Australia explained guide becomes essential for residents. A community battery is a mid-sized battery storage system that serves a local neighbourhood rather than a single home. It allows residents to share renewable energy, lower their bills, and support a greener grid.
Community battery in Australia explained: The basics
A community battery, often called a “neighbourhood battery,” is a shared storage solution. These systems are usually the size of a large fridge or a small SUV. They typically have a capacity of 100kW to 5 MW. Unlike a home battery, a community battery is connected to the local low-voltage power lines.
This placement allows it to absorb excess solar energy from multiple homes simultaneously. During the day, solar panels often produce more power than a household can use. Instead of sending that power back to the main grid at a low fee, it is stored in the community battery.
Use Energy Matters’ easy-to-use solar power and battery storage calculator to determine the size of your solar system with storage! Our solar calculator will generate performance information and potential savings.

How neighbourhoods are sharing solar power
The way these systems work is quite clever. Think of it as a “virtual” storage locker for your electricity. When your solar panels are absorbing sunlight, the excess energy is stored in the local battery. In the evening, when the sun goes down and demand peaks, you draw that energy back.
This process helps create a local energy loop. It reduces the need to transport electricity over long distances from coal or gas plants. Because the energy stays local, it reduces “traffic jams” on the power lines. This community battery model in Australia is a game-changer for grid stability in suburban areas.
Key benefits of community batteries
Why are so many Australian suburbs pushing for these installations? The benefits reach far beyond just simple storage. Here are the primary reasons why neighbourhoods are making the switch:
- Equity for renters and apartment dwellers: Many renters and apartment dwellers cannot install solar panels or batteries because they live in apartments. A community battery project in Australia allows residents to “buy into” renewable energy.
- Lower upfront costs: A home battery can cost more upfront. With a community model, there is no massive upfront cost for the individual household.
- Grid stability: High solar exports can cause voltage spikes on local grid connections. Community batteries absorb this excess, preventing blackouts and protecting home appliances.
- Increased savings: By using stored solar power during peak evening times, residents avoid high retail electricity rates.
- Reduced carbon footprint: These systems maximise the use of local renewable energy. This reduces the reliance on fossil fuels across the entire National Electricity Market (NEM). Use Energy Matters’ carbon footprint calculator to calculate your household and business’s direct emissions.
VPPs and Community storage
Another exciting development is the link between community batteries and Virtual Power Plants (VPPs). A VPP is a network of many smaller batteries working together like one big power station. A community battery system can be the heart of a local VPP.
When the grid is under stress, the VPP can discharge thousands of batteries at once. This helps prevent large-scale blackouts across entire states. By participating, your neighbourhood becomes a vital part of Australia’s energy security. For more information, visit our VPP offers in Australia page.
Challenges and the road ahead
Despite the benefits, there are still hurdles to overcome. Regulatory rules in Australia were initially written for big power plants, not small neighbourhood batteries. This community battery in Australia overview wouldn’t be complete without mentioning these challenges:
- Network tariffs: In some areas, moving power to and from a community battery still incurs “poles and wires” charges.
- Ownership models: Who should own the battery? Options include local councils, energy retailers, or the community itself.
- Revenue streams: To be profitable, batteries must do more than store solar energy. They must also participate in the wholesale energy market.

Major projects to watch in 2026
If you live in Australia, there is likely a project near you. In Victoria, the Yarra Energy Foundation has pioneered inner-city storage.
In New South Wales, Ausgrid has installed “pole-top” batteries that save space in crowded suburbs. This community battery Australia report states that the rollout is accelerating each month. Check out my blog, Ausgrid Introduces NSW’s First Power Pole-Mounted Battery.
These projects demonstrate that we don’t need to wait for major infrastructure changes. We can build a cleaner, cheaper grid one neighbourhood at a time. Sharing power is not just a dream; it is becoming a reality for thousands of Aussies.
How Energy Matters can help
