An Australian state will install the world’s largest lithium ion battery in a “historic” deal with electric car firm Tesla and energy company Neoen.
The battery will protect South Australia from the kind of energy crisis which famously blacked out the state, Premier Jay Weatherill said.
Tesla boss Elon Musk confirmed a much-publicised promise to build it within 100 days, or do it for free.
The 100-megawatt (129 megawatt hour) battery should be ready this year.
“There is certainly some risk, because this will be largest battery installation in the world by a significant margin,” Mr Musk said in Adelaide on Friday.
