What is a community battery?

A community battery stores excess local renewable energy for later use, improving grid stability, lowering costs, and enabling wider solar benefits. Initiatives from TasNetworks and ARENA are driving their deployment in Tasmania and beyond.

A community battery is a mid to large sized energy storage system that stores excess electricity generated by local renewable energy sources such as rooftop solar panels. 

Here's how it works and its benefits:

How a community battery generally works

  • Energy storage: During the day, when solar panels generate more electricity than is needed the excess energy is stored in the community battery.
  • Energy distribution: When energy demand is high, or solar generation is low (e.g., at night), the stored energy is distributed back to the community.
  • Grid support: Community batteries help stabilise the electricity grid by managing energy supply and demand, helping to reduce the need for traditional grid upgrades.

Benefits of community batteries

  • Enhanced solar utilisation: Allows more households to benefit from solar energy, even if they don't have their own solar panels.
  • Cost savings: Could reduce electricity costs by storing cheap, excess solar energy and using it during peak demand times.
  • Grid stability: Improves the reliability and quality of the electricity grid by balancing supply and demand.
  • Environmental impact: Supports the transition to a clean energy future by maximising the use of renewable energy sources.

Examples and initiatives

  • TasNetworks: In Tasmania, community batteries are being installed as part of initiatives to support renewable energy and enhance grid stability.
  • ARENA Funding: The Australian Renewable Energy Agency (ARENA) has funded projects to deploy community batteries across various regions of Australia.

Community batteries are a key component in the transition to a more sustainable and resilient energy system.
