In front of the meter batteries are integrated into the electricity network. There are currently twelve on the grid and they support the network by smoothing energy flows.
A behind the meter battery sits on a customer’s property and is not integrated into the electricity network. Energy generation and storage are managed within the property meaning the homeowner increases their solar self-consumption rather than exporting solar to the grid. We currently have one behind-the-meter battery as part of a trial in Margaret River.
Both batteries work to balance energy flows by reduce peak load (energy usage) on the grid at certain times of day. So they help support the grid, improve power quality and allow further uptake of rooftop solar.
