The pilot projects, with ActewAGL, Snowy Hydro’s Red Energy and Ergon Energy, will be implemented in a selected zone of customers with solar-installed households in the ACT, NSW and Queensland, using Panasonic’s residential energy storage system to complete the analysis.
Storage batteries have the capability to allow more solar energy to be used, with Panasonic modelling for the Australian market showing that the system could increase the self-consumption rate of solar generation from 30% up to as much as 60%.
The residential battery technology stores excess electricity generated during the day by solar panels to provide a reliable, efficient base load for solar-installed households during peak periods. Once fully charged from the day's sun, Panasonic’s lithium-ion storage battery produces a two kilowatt output for four hours.
“Over the 10-year plus life cycle of the battery, our modelling is showing a significant reduction in the reliance of Australian households on the grid during peak periods.
“The pilot projects are a first for Panasonic in Australia, and Panasonic’s battery demand response system will help distributors model peak shaving effects, realised through solar and battery storage systems and provide a cost effective alternative to grid infrastructure investments.”
“Reid said that, for consumers, it means access to clean solar energy during the evening peak and potentially a lower energy bill. “For the retailer, we can provide a levelling out of costs and potential competitive advantage with customers.”
