Study finds Cultana seawater pumped hydro project feasible

Cultana -
Cultana area Spencer Gulf

A consortium of EnergyAustralia, Arup and The University of Melbourne’s Energy Institute (MEI), with funding assistance from ARENA, has undertaken a feasibility study for a seawater pumped hydro project in South Australia’s Spencer Gulf. The study found that the the project is technically feasible with a capital cost of just over $2.1 million per MW of capacity and $270 per kWh of storage. This is towards the high side for pumped hydro projects due to relatively long penstocks and the significant structures to exchange water with Spencer Gulf.
