The founder of Tesla, billionaire entrepreneur Elon Musk officially revealed the world’s largest battery on Friday in South Australia, capable of providing electricity for more than 30,000 homes, Australian state officials confirmed. The battery, known as the Powerpack system was engineered and built by Musk’s Tesla in order to prevent future energy blackouts in South Australia such as the one in 2016 caused by an “unprecedented” storm. The 100 MW/129 MWh battery, located in the rural town of Jamestown just north of Adelaide and connected to a wind farm run by French energy firm Neoen, was powered up a day earlier to help local residents cope with extremely high temperatures. The wind farm is expected to tackle power outages, reduce intermittencies and meet higher demand for power during the hot days of summer in Australia.
Musk presented the idea of building the world’s largest battery earlier this year on Twitter, when he offered to complete the whole project in just 100 days. By finishing it last week, he beat his own deadline by a couple of days. Tesla stated that the project, which cost around $50 million, could set standards for similar undertakings in the future all around the world, while its swift completion “shows that a sustainable, effective energy solution is possible.” Meanwhile, Australian state authorities also praised the project. “South Australia is now leading the world in dispatchable renewable energy, delivered to homes and businesses 24/7,” state Premier Jay Weatherill said, adding that “this is history in the making.”
