The power grid in South Australia now has a giant Tesla battery.
As a reminder, on March 9, Elon Musk tweeted that he would deliver 100MWh of energy storage to South Australia in 100 days. He made good on that promise, and finished the job in 63 days.
"This is history in the making," said South Australia Premier Jay Weatherill. The battery system is sitting next to wind turbines at the Horndale Power Reserve. "South Australia is now leading the world in dispatchable renewable energy, delivered to homes and businesses 24/7."
The battery can store enough energy to supply energy to 30,000 homes for more than an hour. The main reason South Australia was seeking out this technology is that they need stability for the South Australia electrical grid.
The Tesla batteries were successful in testing, and were used a day earlier than planned. Temperatures were over 100 degrees, so the Tesla energy storage was tapped to make up the energy needed for air conditioning.
South Australia's taxpayers will be paying $50 million over 10 years to subsidize the cost to operate.
