Additional information
The South Australian Government is playing an instrumental role in this project by committing $3 million AUD per year for 5 years in grant funding toward the expansion through its Grid Scale Storage Fund, to secure the delivery of the inertia benefits highly needed by the grid. On behalf of the Australian Government, the Australian Renewable Energy Agency has committed $8 million AUD in grant funding through its Advancing Renewables Program. The project will also be the first battery project in Australia to benefit from debt financing support from the Clean Energy Finance Corporation (CEFC). Network connection works have been completed for the project.
Methodology
All publicly-announced energy storage projects included in this analysis are drawn from GlobalData’s Power IC.
