The world's first big battery is even bigger
In September 2016, a once in 50-year storm damaged critical infrastructure in South Australia, causing a state-wide blackout. In response, together with the South Australian Government and Neoen, Tesla installed the world’s largest lithium-ion battery, the 100MW Hornsdale Power Reserve. In 2020, the world's first big battery is now bigger. Increased by 50% to 150MW, it continues to support the grid and provide frequency control, supporting South Australia's sustainable future.
