Elon Musk's giant lithium ion battery completed by Tesla in SA's Mid North.
Tesla has completed construction of its giant lithium ion battery, described as the world's most powerful, with testing expected in coming days ahead of a December 1 operation deadline.
The array of Tesla Powerpack batteries has been installed alongside French company Neoen's Hornsdale windfarm near Jamestown in South Australia's Mid North region.
South Australian taxpayers will spend up to $50 million subsidising the 100-megawatt battery.
In return, the SA Government will have access to some of the battery's output to provide stability services to the grid.
"The world's largest lithium ion battery will be an important part of our energy mix," Mr Weatherill said.
Mr Weatherill visited the battery site at the end of September with Tesla boss Elon Musk, to mark the halfway point of construction. »
