"A community battery is a relatively new concept in Australia. It is a shared battery solution located in a local neighbourhood and allows customers and the wider community to share in the multiple benefits that batteries can provide." (See Ausgrid "Community Batteries")
Labor’s Community Battery policy will reduce power bills and emissions for hundreds of thousands of Australians.

Being able to aggregate data at a "community level" will be very helpful.

Consider this data at the level of a single dwelling:
5kW peak demand, 24 kWh / day total.
Now: 5 kW generation and grid capacity needed, mostly unused.
Storage: Only 1 kW of capacity needed.
Under ideal conditions, only 1 kW of generating capacity and grid capacity is needed to provide the total of 24 kWh per day used by the above single dwelling. The "community battery" provides the peak demand of 5 kW from time to time during each day as appliances switch on and off.
The battery can be an alternative infrastructure item, potentially replacing 4 kW of generating capacity and grid capacity for the single dweliing in this example.
Even if there is no rooftop solar PV systems in some communities, the ability to charge a community battery overnight - when generation and grid capacity is otherwise idle - can help to lower peak capacity needed the following day.

Policy to raise grid investment to be reviewed?
