Report extract
Following the state-wide blackout across South Australia (SA) in 2016, Neoen and Tesla were selected by
the South Australian Government to supply Australia’s first grid scale battery named the Hornsdale Power
Reserve (HPR). This project was commissioned in 2017 with a nameplate capacity of 100MW/129MWh. In
November 2019, Neoen, in collaboration with the South Australian Government, the Australian Renewable
Energy Agency (ARENA), and the Clean Energy Finance Corporation (CEFC), unveiled plans for Hornsdale
Power Reserve Extension (HPRX) with an additional 50MW/64.5MWh capacity, bringing the combined
installed capacity of HPR to 150MW/194MWh
