But now instead of being a large centralized battery system using Tesla's Powerpacks, the new project announced today is using Tesla's residential battery system, the Powerwall, to create decentralized energy storage, which basically results in creating a massive virtual power plant.
South Australia Premier Jay Weatherill announced the deal today – the biggest of its kind by far.
The 50,000 homes in the state will be fitted with 5 kW solar arrays and 13.5 kWh Tesla Powerwall 2 battery systems.
It will result in at least 650 MWh of energy storage capacity distributed in the state.
Tesla said in a statement:
"When the South Australian Government invited submissions for innovation in renewables and storage, Tesla's proposal to create a virtual power plant with 250 megawatts of solar energy and 650 megawatt hours of battery storage was successful. A virtual power plant utilises Tesla Powerwall batteries to store energy collectively from thousands of homes with solar panels. At key moments, the virtual power plant could provide as much capacity as a large gas turbine or coal power plant."
It will function much like Tesla's giant Powerpack system, which charges when demand and electricity rates are low and discharges when demand and prices are high.
Aims to install 5 kW solar arrays and 13.5 kWh Tesla Powerwall 2 battery systems in 50,000 homes by 2022.
