Tesla was selected to provide a 100 megawatt (MW), 129 megawatt-hour energy storage system to be paired with Neoen’s 315 MW Hornsdale Wind Farm near Jamestown, South Australia. Tesla was awarded the entire energy storage system component of the project.

Tesla Powerpack will charge using renewable energy from the Hornsdale Wind Farm and then deliver electricity during peak hours to help maintain operation of South Australia's electrical infrastructure.

Upon completion by December 2017, this system will be one of the largest lithium-ion battery storage projects in the world.

The wind farm will consist of up to 105 3 MW wind turbines.

In September 2016, a 50-year storm damaged critical infrastructure in the state of South Australia, causing a statewide blackout and leaving 1.7 million residents without electricity. Further blackouts occurred in the heat of the Australian summer in early 2017.

In response, the South Australian government called for expressions of interest to deploy grid-scale energy storage options with at least 100 MW of capacity.
