In partnership with Synergy, we’ve been running an Australian-first two-year trial in Meadow Springs, Falcon and Ellenbrook.
Our initial trial in Meadow Springs allowed us to test the physical capabilities and needs of the batteries and infrastructure, which has proven to be both robust and efficient.
Participants could store their excess rooftop solar during the day in the battery, and then use the power later when they were no longer generating solar energy.
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.
Each of the participating households were also given an advanced meter, so they could learn more about their own energy use.
We’ve also learned that the PowerBank batteries work particularly well for households who generate a lot of solar energy during the day, but aren’t home to use it. It’s also proven to be up to 30% cheaper than buying an in-home battery.
However, the trial also demonstrated that if you have solar panels and efficiently use that energy during the day, a PowerBank battery, or any type of battery, isn’t likely to benefit your household, so battery storage is not an effective option for everyone.
From a network perspective, PowerBank batteries have shown to be an effective tool in helping the network cope with peak solar power generation in high solar areas like Meadow Springs, smoothing the flow of energy and reducing the chance of faults.
