Pumped hydro potential for Tasmania

Tribute_bathymetry-112-small

Coal is retiring, and new sources of renewable energy like wind and solar are becoming more plentiful. As our energy mix changes, we need to maintain the reliability, stability and security of the electricity system. Energy storage is needed to "fill the gaps" and provide a stable, reliable electricity system.

Lake Cethana has been selected as Hydro Tasmania’s preferred site of its top three Tasmanian pumped hydro opportunities and it will now progress to final feasibility.

Deep storage capacity, greater cost certainty, environmental and social sustainability and flexibility in sizing and capacity make Cethana the front runner to finalise feasibility.

Please take a look through our FAQs below and get in touch with our team at pumpedhydro@hydro.com.au if there’s something else you’d like to know. We're out talking to communities in February and all the details are below.
