The world's largest lithium battery was activated in Australia on Friday, fulfilling the pledge by Tesla CEO Elon Musk to build it in 100 days or provide it for free, CNN reported.
The electric car company’s Powerpack battery system stores energy generated by a nearby wind farm in South Australia, and it is capable of providing electricity for as many as 30,000 homes, CNN reported.
“South Australia is now leading the world in dispatchable renewable energy,” the state's premier, Jay Weatherill, said in a statement Friday. “This is history in the making."
Tesla said it hopes the project “provides a model for future deployments around the world.”
Musk made his "100 days or it's free" vow on Twitter during an exchange with Australian billionaire Mike Cannon-Brookes, CNN reported. The promise began with the official contract was signed in September.
With the battery going online this week, Musk met his deadline. The battery was officially launched Friday, but Australian media reported that it started supplying power to the electricity grid Thursday during peak demand hours.
