According to this story from Electrek, the government in South Australia is working with Tesla to install 5kW solar arrays and 13.5 kWh battery packs on 50,000 houses, including 1,100 low-income houses, creating what amounts to 250MW virtual power plant, with 650MWh of battery storage. Australia seems to be embracing the modernization of its electrical grid having just complete a 129MWh battery site just this past Fall.

Now if only we could fix Puerto Rico with his solution.
