Queensland PHES atlas
Queensland has many potential sites for pumped hydro energy storage (PHES).
The number of upper storage sites located in our initial survey is 1769, with an approximate
energy storage potential of 6779 GWh – approximately 100 times larger than the amount of
storage required to support a 100% renewable electricity grid for Queensland. This large number
provides some confidence that there will be a good number of technically feasible PHES sites.
Pumped hydro energy
storage (PHES) is the most mature and widely deployed electricity storage technology
worldwide – 97% of globally installed grid storage is pumped hydro.
These sites were found using algorithms with defined search criteria within a geographic
information system (GIS) platform. This platform was used to find detailed information, such
as head, reservoir areas, and storage capacity. This list is not yet exhaustive. We are also in the process of developing a cost
model that will determine the least cost option for the tunnelling between two reservoirs,
and therefore the location of the lower reservoir. This information will be available
in future releases of the atlas.
