Customers are allocated virtual storage in the battery. As their solar panels generate solar power during the day, up to 6kwh or 8kwh of excess or unused power is automatically transferred to the battery.
From 3pm to midnight households can draw energy back from the battery to power up their homes, covering the energy-use peak hours between 3pm and 9pm. At midnight, any excess power still in the battery is returned to the grid, with the householder paid the standard feed-in tariff.
We have been running an Australian-first trial in Meadow Springs where 49 customers were plugged into a community battery for a two-year period.
The participants could store their excess rooftop solar during the day in the community battery, and then use that power later when the sun was absent.
A range of customers with different household energy use patterns participated, with the battery cost highly subsidised. This gave us a chance to test what kind of household energy use best suits the battery solution, and how much excess power they needed to store.
As each of the participating... Read more
If you have solar panels that are creating power when you are not home during the day, this solution may suit you. This solution may also suit you if you have been considering buying an in-home battery.
Can anyone get involved in a community battery?
You need to live in the local area and be invited to be part of a PowerBank trial. We will reach out to households with the right parameters of energy use and solar that is suited to a community battery and work through the recruitment process with interested households.
