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.

They built a terrible Grid, it failed very badly before Hurricane Maria even came. And it's still in terrible shape. We did so much to help them. I suspended the Jones Act for 10 days. At horrendous cost to our American shipping industry. And I went to Puerto Rico personally, I handed out paper towels, they needed so many paper towels to wipe up that terrible mess, more than Hillary used to wipe her EMAILS. And they survived amazingly well. The official death toll is what, 3 or 4? Versus in the thousands with Katrina. They can be very proud of all of their people and all of our people working together. Let me tell you, it would have been PERFECTO if they had a good Grid. Their Grid is a disaster, everything else is amazingly great. They're doing better than they ever have.
I don't want America to become like Puerto Rico. Our Coal & Nuclear, some of them can keep 90 days of fuel at the site. Which was how our subsidy was going to work. If they can keep 90 days of fuel, they get the subsidy. If they can't, no subsidy. Solar & wind, where do they keep the fuel? There's no fuel. The wind can stop blowing, the Sun can stop shining any time. And suddenly you have no lights. Just when you need them the most. You want your lights to stay on, you need a big battery. Or you need Coal & Nuclear. Australia, they have so much Coal. They have so much Uranium. They're being very foolish!
