A community storage pilot project using Tesla batteries went live this week in Western Australia, three months ahead of schedule. The 105KW/420KWh pooled storage will act as a sort of locker for excess power produced by homes with solar panels.
The project is an unusual one because it pools battery capacity for homes with solar panels. It was funded by energy company Synergy and government-owned Western Power, which sought 52 customers with solar panels on their homes as participants. The 52 shares of the project were snapped up in two weeks, far more quickly than expected, which accelerated the project’s timeline.
Participants will each be allotted 8kWh of storage, which they will “fill” with excess power created by their rooftop solar panels during the day. (This is in theory, of course. Solar-generated electricity can flow back onto the grid, but there’s no guarantee that the battery will be charged with solar-generated electrons.) In the evening, customers will “be able to draw electricity back from the PowerBank during peak time without having to outlay upfront costs for a behind-the-meter battery storage system,” says a press release from the government of Western Australia.
