At 100MW/129MWh, the Hornsdale Power Reserve is the largest lithium-ion battery in the world, and is providing essential grid-support services.

The 50MW/ 64.5MWh expansion, currently under construction, will further showcase the complete benefits that grid-scale batteries can provide to the National Electricity Market (NEM) and Australian consumers.

In its first two years of operation, the project saved South Australia consumers over $150 million.
