Synergy has been trialling a 1.1 megawatt community-scale lithium ion battery in the new Alkimos Beach estate since 2016.
The system was expected to save households money. For $1 a day residents will be able to use 8kWhs of the powerbank battery storage after 3pm without having to outlay upfront costs for a behind-the-meter battery storage system…
