The Environmental Impact Statement indicates an alternative configuration of 400MW over 9-hours is possible, subject to network capacity. Water will be transferred between a purpose-built upper reservoir and an existing dam on the mine site via a tunnel, with the initial water supply drawn from the mining complex itself.
The project is expected to deliver around 13% of NSW’s 2034 long-duration storage target. A Voluntary Planning Agreement with Mid Coast Council will deliver AU$18.2 million in community and infrastructure funding over the life of the project. Up to 350 construction jobs and 10 ongoing operational roles are anticipated.
New South Wales Minister for Planning Paul Scully described the approval as the first of its kind in the state for six years.
“Projects like Stratford Pumped Hydro show how we can make the most of former mining sites and create new jobs and industry which will help to drive the region’s economic growth for decades to come,” he said.
Mine repurposing as a cost lever
