A community battery is a shared neighbourhood battery solution that supports the grid by improving power reliability and smoothing power flow in a local area to enable further uptake of rooftop solar. Currently, a community battery doesn’t allow for individual storage (meaning you can’t draw on it to power your home when you’re not generating any solar energy) unless it is a PowerBank battery.

The PowerBank battery is being used in our community battery trials with Synergy, where in selected areas participants can store excess energy and then draw on it when needed to power their homes. PowerBank is the name of the battery we’re using. A community battery is another battery storage solution, however households who have access to one can only send their excess solar energy to the battery to support the grid, not draw energy from it.

A PowerBank is a type of community battery, situated in a local area, that is shared by eligible customers who generate solar energy. Each PowerBank customer has a storage capacity of 6kwh or 8kwh.

We currently have PowerBank batteries running in Meadow Springs, Falcon and Ellenbrook. These are in partnership with Synergy.

In partnership with Synergy, we recruit for people to be involved in each trial, based on what we know about the type of household the community battery suits. We will be in touch if we think your household is suitable for an upcoming community battery installation.
