Australia, World: Tesla to build world’s largest lithium ion battery for renewable energy storage

Elon Musk, the billionaire founder of Tesla, will build the world’s largest lithium ion battery to store renewable energy in South Australia in partnership with French energy utility Neoen.

The 129MWh battery, which is paired with a wind farm, is designed to improve the security of electricity supplies across South Australia.

On Friday the state’s premier, Jay Weatherill, confirmed the deal, which forms a key part of the government’s $550m energy plan.

The state government said Musk had confirmed his pledge made on Twitter in March that he could deliver the battery within 100 days of signing the contract or it would be delivered free.

Romain Desrousseaux, the deputy chief executive of Neoen, said that at 129MWh the South Australian lithium ion battery would become the largest in the world. The battery will be built near Jamestown, in the state’s mid-north, and will be paired with Neoen’s Hornsdale windfarm to provide stability for renewable power being fed into the grid.

Musk told reporters in Adelaide on Friday the project was not without technical challenges, given it would be the largest battery installation in the world “by a significant margin”.

“When you make something three times as big, does it still work as well? We think it will, but there is some risk in that,” he said. “We’re confident in our techniques and the design of the system.”

He anticipated it would help stabilise the grid and help bring down prices for consumers.
