Tesla mega-battery activated01/12/17Energy
The world’s largest lithium ion battery has begun dispensing power into an electricity grid in South Australia.
The 100-megawatt battery, built by Tesla, was officially activated on Friday. It had in fact provided some power since Thursday due to demand caused by local hot weather.
South Australia has been crippled by electricity problems in recent times. Elon Musk vowed to build the battery within 100 days, and that promise was fulfilled.
South Australian Premier Jay Weatherill has described the battery as three times more powerful than the world’s next biggest battery, and will prevent a repeat of a notorious incident last year when the entire state lost power.
When fully charged, the battery can power up to 30,000 homes for an hour. However, it will mostly be used to support and stabilise existing electricity supplies.
The battery is comprised of a grid system that runs on the same technology that powers Tesla’s cars.
In a statement, the company said the completion of the battery “shows that a sustainable, effective energy solution is possible”.
