The ginormous battery can provide up to 100 MW of power and to subsidise this, Australian taxpayers have to shell out $50 million an ABC News report claimed.

A huge blackout in September of last year had left much of theSouth Australian homes devoid of power. However, Tesla's battery is tipped to supply enough electricity to power up over 30,000 homes in the region, which is roughly the number of homes that were affected by the blackout according to the report. The entire project came across after some Twitter banter by Australian billionaire Mike Cannon-Brookes who asked that if he could supply the funding, would Musk be willing to complete the battery in 100 days? Musk replied that if the battery wasn't done in 100 days he would pay the entire bill, which would amount to $50 million. Elon musk kept good on his promise by delivering before the deadline, but to be honest, according to the Mashable report Musk was already half-way done before taking up the 100-day challenge (Well played Elon!). In a media report Premier Jay Weatherill said, "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 leading renewable energy with battery storage."While the battery completion marks out as a success for Tesla and Elon Musk, there are still looming problems surrounding the production of the Model 3 sedan which is widely believed to secure the company's future.Tesla spent $1.1 billion on its auto business in the third quarter and expects expenses of $1 billion in the current one. It had about $3.5 billion in cash and cash equivalents as of 30 September. At the current cash-burn rate, it would likely be down to about $1 billion in cash by the end of the first quarter.
