On Friday 1 December, the world’s largest lithium-ion battery will become operational. Elon Musk just won a USD50-million bet. These two things are definitely related.

In March this year, Tesla founder Elon Musk made a bet on Twitter with Mike Cannon-Brookes, the co-founder of Australian enterprise software company Atlassian, that he would be able to install the world’s largest lithium-ion battery in Australia within 100 days, or he would supply it for free.

The contract was signed on 29 September (although construction of the battery was already half complete), and Musk announced completion of the build last week. From the day the bet was made to the day the battery was turned on? 183 days!

According to the Sydney Morning Herald, Tesla is currently busy with final tests before the USD50-million 100MW battery goes live tomorrow.


And as for the man on the other side of the bet, Mike Cannon-Brookes, well, he’s certainly not complaining.

The battery, which can provide 129MWh of energy, comprises Tesla PowerPacks, and is attached to French firm Neoen's 325MW Hornsdale wind farm, in construction near Jamestown, South Australia. It forms part of South Australia’s AUD550-million plan to power the state.
