Trial to revolutionise battery storage in WA

A trial by Western Power and Synergy will aim to make battery storage more accessible and manageable for Western Australians.

The PowerBank trial will be the first time in Australia that a utility-scale battery is integrated into an already-established major metropolitan network, to allow a shared storage service to meet an individual customer’s needs.

A 105kW (420kWh) Tesla battery will be owned and operated by Western Power and Synergy and connected to the grid in Meadow Springs, allowing households with solar panels to maximise their existing grid connection.

Customers participating in the 24-month trial will be able to virtually store excess power they generate during the day from their solar PV systems in the battery, and then draw down on that power during the peak evening period.

These customers will be able to use 8kWhs of the PowerBank battery storage without having to outlay upfront costs for a behind the meter battery storage system. This is enough to power the average suburban home for over one hour during peak time.

PowerBank trial participants will be given greater access to their usage patterns and daily storage data online via the Synergy website, while maintaining reliability of supply from their Western Power grid connection during overcast days.

Homes taking part in the trial will not be locked into the program, which will allow them continuing flexibility and choice in deciding how they meet their individual electricity needs.

Customers will also receive a quarterly activity statement advising of savings to date, using a system developed by Synergy.

Energy Minister Ben Wyatt says the trial is another Australian milestone for the application of utility-scale batteries for the benefit of customers.

“At the cost of one dollar a day, customers will have access to 8kWh of battery storage to use any time after 3pm each day,” he says.

The recruitment of participants for the trial has begun, with Synergy contacting those eligible by mail.
