Elon Musk has an ambitious new project on his plate: building the world's largest lithium-ion battery. The 100 megawatt battery, which will be put together by Tesla and French energy company Neoen, will store renewable energy for the state of South Australia, the Guardian reports. The battery will be linked up with a wind farm near Jamestown and able to power 30,000 homes, per Reuters; it will hoard extra energy created by the wind farm during non-peak times then offer up its stores during emergency situations, New Scientist reports. "This will be the highest power battery system in the world by a factor of 3," Musk tweeted, echoing comments made in Adelaide Friday where he said "the next biggest battery in the world is 30 megawatts," reports the BBC.
The New York Times reports that an offer from Tesla's battery division emerged in March after "a string of embarrassing power outages" in South Australia, and the state's government confirms the Tesla CEO is standing by his pledge made that same month that if Tesla can't produce the battery within 100 days of signing a contract, it will be gifted free of charge. The BBC suggests that countdown clock has not yet been set, and will be after the signing of an "electricity grid interconnection agreement"; media reports indicate the battery will be put in place before December. "South Australia is already leading the nation. Today, we lead the world," South Australia Premier Jay Weatherill tweeted Friday, showing a pic of himself and a grinning Musk. (A "Tesla for the masses" comes out Friday.)
