"Tesla and power producer Neoen will expand by 50 percent the world’s largest lithium-ion battery in South Australia to ensure additional grid stability, the French company said on Tuesday.
Neoen will expand the Hornsdale Power Reserve battery, also known as the Tesla Big Battery, which Tesla started to build two years ago. At the time, Tesla was selected through a competitive bidding process to provide a 100 MW/129 MWh Powerpack system to be paired with Neoen’s Hornsdale Wind Farm near Jamestown.
Now Neoen, supported by Tesla, will expand the battery with 50 MW/64.5 MWh to offer additional grid stability and cut electricity costs for consumers.
The expansion is expected to be completed in the first half next year, the French renewable power provider said in a statement.
In its first year of operation, the Tesla Big Battery has saved consumers more than US$34 million (AU$50 million), Neoen says, noting that the expansion will lead to additional savings for consumers."
