In 2017 and following an Expression of Interest process, the South Australian government announced Tesla in conjunction with Neoen to build a 100MW/129MWh lithium-ion battery in Jamestown. Neoen then completed a 50MW/64.5MWh expansion of the battery in 2020 after being granted $15 million from the South Australian government and $8 million from the Australian Renewable Energy Agency (ARENA).

Already delivering grid support services since its inception, the battery continued its world leadership in 2022 by being the first big battery in the world to deliver grid-scale inertia services through Tesla’s Virtual Machine Mode. With support from the South Australian government, these world first services further demonstrate South Australia’s leadership in the renewable energy.
