The Australian Renewable Energy Agency (ARENA) has today announced its support of a feasibility study to assess the potential to turn a mothballed mine in South Australia into a 90MW pumped hydro energy storage (PHES) plant.

On behalf of the Australian Government, ARENA is committing $500,000 to GFG Alliance to begin the first phase of establishing the technical and commercial feasibility of bringing a disused mine site in the South Middleback Ranges, near Whyalla, back to life as a potential PHES power plant.
The $1.7 million project will investigate if the existing mine pit of “Iron Duchess North” could be utilised as a lower reservoir for a PHES plant creating an estimated capacity of 90 MW and 390 MWh of storage.
Pumped hydro works by pumping water uphill between two connected reservoirs when electricity is cheap and abundant, and running water downhill to power turbines when electricity is needed.
