ARENA (Australian Renewable Energy Agency) announced that they will be supporting 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, the agency is going to commit $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 to be a potential PHES power plant.
The $1.7 million project will explore the possibility if the existing mine pit of “Iron Duchess North” could be used as a lower reservoir for a PHES plant, creating an estimated capacity of 90 MW and 390 MWh of storage.
Expected to be completed by late 2018, the first stage of the study will be about the high-level designs, engineering studies, network studies, geotechnical investigation, market modeling and commercial evaluation.
The $170 million Middleback Ranges PHES plant could be built by 2022 if successful.
ARENA CEO Ivor Frischknecht said the feasibility study was the first stage in assessing possible sites to store South Australia’s growing renewable energy generation.
“South Australia has ideal wind and off grid solar power resources to support large-scale renewable generation, so we will need energy storage options to harness and store this capacity so it is available at all times.
“We are excited to explore the potential of old mining assets being turned into renewable energy storage which can provide dispatchable and reliable power,” he said.
Alongside feasibility studies into other pumped hydro across Australia including Snowy 2.0, Hydro Tasmania’s Battery of the Nation projects and EnergyAustralia’s proposed seawater PHES project at Cultana, ARENA is also providing funding to support the Kidston hybrid solar and PHES project in a mine in Queensland.
“We thank ARENA for its support to this important project. This unique pumped hydro storage project is a great opportunity for SIMEC ZEN Energy (part of GFG Alliance) to obtain real-world insights and apply the learnings to offer expert energy contracting solutions to customers seeking secure, affordable and low emission energy to transition through their current energy challenges,” says SIMEC ZEN Energy CEO Geoff Titus
“We look forward to working with Liberty Onesteel in the first instance on the benefits this project will provide, and then establishing partnerships with other large energy users across Australia seeking a new way of contracting energy for their long-term success.”
Titus also said that the project would offer many benefits for the company and residents.
