    This pumped hydro project was completed on 11 December 2017.


The EnergyAustralia South Australian (PHES) Feasibility Study project aims to determine the technical and economic feasibility of a seawater Pumped Hydro Energy Storage (PHES) plant, located south-west of Port Augusta, in South Australia.


PHES can provide large scale storage to balance the intermittency from various forms of renewable energy. The project has considerable demonstration potential, given the need for balancing generation and other services related to maintaining system stability.

Project innovation

The EnergyAustralia South Australian (PHES) Feasibility Study further inform the market on key challenges in deploying PHES in Australia using seawater.


The application of pumped hydro using sea water could open up a significant opportunity to deploy this form of storage around Australia.
