Energy storage is important in securing the stability of an electricity grid. Pumped hydro energy storage, or PHES, could have a huge impact upon the Australian electricity grid. The great majority of energy storage installed globally is PHES. This project focuses upon the resource potential within Australia and other countries. This work searches for pairs of dams with an altitudinal difference of more than 250 m, and excludes residential areas, national parks and other sensitive places.

We have published an atlas covering all of Australia.
