Pumped hydro projects unveiled as Tasmania bids to be 'battery of the nation'

State and federal governments to confirm that 14 lake sites have been earmarked

Pumped hydro projects generating energy at twice the scale of the much-vaunted Snowy 2.0 scheme will be identified across Tasmania on Wednesday, with modelling suggesting the proposal could deliver thousands of jobs between now and 2028.

The Turnbull and Hodgman governments will confirm that 14 pumped hydro sites have been earmarked across the state with a combined potential generation capacity of up to 4,800 megawatts.
