The virtual power plant involves installing a 5-kilowatt solar system and a Powerwall 2 battery on roughly 50,000 low-income and social housing units across the state over the next four years. The setup would be installed at no charge to the households and financed through the sale of electricity. Participants would save an estimated 30 percent on their power bills.
“My government has already delivered the world’s biggest battery, now we will deliver the world’s largest virtual power plant,” Weatherill said then. “We will use people’s homes as a way to generate energy for the South Australian grid, with participating households benefiting with significant savings in their energy bills.
Tesla told AFP that the virtual power plant would have 250 megawatts of solar energy and 650 megawatt hours of battery storage.
“At key moments, the virtual power plant could provide as much capacity as a large gas turbine or coal power plant,” the company added.
Van Holst Pellekaan also said at the Australian Energy Conference that the trial phase, which starts with installing home energy systems on 1,100 public housing properties, is currently proceeding.
