Back in March we wrote that Tesla will kill the duck in Australia in 100 days or it’s free. Elon Musk promised to deliver a 100 MW lithium battery system that would shave off the peaks of demand and kill the duck curve with "the world's largest lithium ion battery." Not only that, he would deliver it in under a hundred days or it was free -- basically, a $50 million dollar bet. But note the words in there "from contract signature." Crossing the i's and dotting the t's took a bit of time, and the contract wasn't actually signed until the end of September, when the project was in fact half done. (The photo at top was taken on September 29th when they announced the signing.) Now it's done, with 45 days left before the hundred days is up. After a little bit of testing, it is likely that the batteries will be working by the first of December. The Premier of South Australia is not unhappy to lose this bet: While others are just talking, we are delivering our energy plan, making South Australia more self-sufficient, and providing back up power and more affordable energy for South Australians this summer. The world’s largest lithium ion battery will be an important part of our energy mix, and it sends the clearest message that South Australia will be a leader in renewable energy with battery storage. © Getty Images/ Mark Brake/ Wind farm on September 29 As Tesla noted in its press release earlier, the batteries are paired with the Hornsdale Wind Farm near Jamestown, South Australia. Tesla Powerpack will charge using renewable energy from the Hornsdale Wind Farm and then deliver electricity during peak hours to help maintain the reliable operation of South Australia's electrical infrastructure. The Tesla Powerpack system will further transform the state’s movement towards renewable energy and see an advancement of a resilient and modern grid. © Ravinder Soin, Midnight Energy And, as is appropriate on this American Thanksgiving Day, it will help kill the duck.
