Musk's legion of Twitter followers quickly dug out a tweet sent in March stating that Tesla will pledge to have the system installed and working 100 days from the date of the contract signature, otherwise the energy will be delivered for free.
The grid-scale energy storage system will be deployed alongside the Hornsdale Wind Farm near Jamestown, which is operated by Neoen.
Elon Musk himself bragged that the system would be up and running within 100 days or it's free, and Tesla is aiming to make good on that promise, setting the project's completion date for December.More news: House Passes Bill Defunding Sanctuary Cities
Tesla has entered a partnership with an Australian state to build the world's biggest battery.
Jay Weatherill, the premier of SA, today said that the project would "stabilise the South Australian network as well as putting downward pressure on prices". The South Australian government has been seeking to fix the problem with renewable energy.
South Australia, which relies heavily on solar and wind-generated energy, has been scrambling to find a way to bolster its fragile power grid since the entire state suffered a blackout during a storm a year ago.More news: Xi, Modi unlikely to meet at G20 due to border row
Tesla said the project would be completed by Decemeber 2017 and "will provide enough power for more than 30,000 homes, approximately equal to the amount of homes that lost power during the blackout period".
"Together, the South Australian government, Neoen and Tesla will demonstrate that renewables can provide dependable, distributable power that will turn a new page in Australia's energy future", he said.
Musk said the new battery will be 100 megawatts in capacity.
The objective of the battery is to stabilise the supply of renewable energy.More news: China's Xi warns against 'impermissible' challenges in Hong Kong
"And I think long term, because it'll be three times more powerful than the next biggest battery installation in the world". Arrays of battery packs will store energy generated by renewable sources in an effort created to help alleviate blackouts.
