What is a community battery?

Community batteries are a new concept in Australia. 

A community battery is a battery that is shared by customers who have a solar panel system and are connected to the same local Ausgrid network.  

Customers connected to a community battery can use it to store their excess solar power and access it as needed later that day (or night). In future, customers could even sell it to other community members, or even donate their spare energy to charity! 

It requires no upfront investment compared to installing your own home battery and will provide a great option to save on your energy costs.  

Community batteries can also be flexible in design, allowing customers to grow or shrink their share of the battery as their circumstances change. 

Community batteries also help electricity distributors like Ausgrid deliver electricity to the community at a lower cost, which can lead to lower bills for all consumers.  

Who can benefit from a community battery?

Local solar customers 

Community batteries can offer a more cost-effective alternative to installing your own battery storage. Some of the benefits include: 

Reduced costs: 

  • No upfront battery installation costs 
  • No maintenance costs – including risk of battery failure 
  • No need to pay for a new battery at end of life 

Greater choices: 

  • Customers can choose a unique storage size for their needs 
  • Customers can ‘flex’ their battery size to suit their changing circumstances 
  • No space for a battery? No problem! A community battery doesn’t take up space in your garage or on your front porch.  

All customers

Community batteries don’t just save on bills for local solar customers.  They save on bills for everyone.  


Community batteries can: 

  • Help make our energy supply clean and green by supporting and encouraging greater uptake of solar by households and businesses. 
  • Increase the number of batteries in the energy system, which can reduce peak demand and place downward pressure on energy prices. 
  • Make access to energy storage more equitable, giving everyone the ability to save on their bills. 
  • Offer a better and cheaper alternative to traditional network investment.  
  • Offer a cheaper way to provide storage to the community as larger, shared batteries are cheaper to buy and maintain than lots of smaller, individual batteries in homes.
