We supported the feasibility study for this project, which, once built, is forecast to be able to power approximately 3 million homes over a week. Our purpose is to support the global transition to net zero emissions by accelerating the pace of pre-commercial innovation, to the benefit of Australian consumers, businesses and workers.
By connecting investment, knowledge and people to deliver energy innovation, we are helping to build the foundation of a renewable energy ecosystem in Australia. We have identified that PHES will play a significant role in helping Australia transition to renewable energy, and will continue to provide funding support and guidance to assist with development and financing.

Massive open cut pits will be repurposed to hold water for energy storage at a mine in north Queensland. How is hydroelectricity produced? How does pumped hydro energy storage work?
Latest media releases. Basslink voluntary administration Nov 12, Hydro Tasmania is aware of the announcement by Keppel Infrastructure Trust and Basslink interconnector continues to operate through this process. Delivering strong results and transforming for the future Oct 28, Despite another challenging year with ongoing impacts from COVID, Hydro Tasmania has delivered significant achievements and a transformation of our business for the future, as outlined in our Annual Report tabled today in Parliament.
Preferably, the reservoirs are not located below any significant catchment to avoid the cost associated with coping with occasional floods. Some potential sites will be unsuitable because of poor geology, restrictions on allowed land use or poor access.
The three common types of site are:. Pipes, pumps, turbines, generators, substations and powerlines are standard equipment that is widely available from the hydro-electric power industry. Construction of reservoirs within Australia also draws upon extensive experience in the construction of farm dams and tailings dams for mining operations.
Most of the costs of off-river and conventional on-river pumped hydro energy storage are similar. The main difference is that off-river pumped hydro energy storage uses relatively tiny and low-cost reservoirs that have a much larger head and do not require expensive flood control. Costs of off-river pumped hydro energy storage systems are relatively predictable because each off-river pumped hydro energy storage site looks much like another, whereas river valleys vary greatly.
There are effectively an unlimited number of suitable sites for pumped hydro energy storage.

Pumped hydro energy storage Pumped hydro energy storage PHES constitutes most energy storage worldwide. How pumped hydro could solve the storage problem , ARENA website, 20 August In addition to storing energy, pumped hydro energy storage has additional capabilities that help support the electricity system. Off-river pumped hydro energy storage differs significantly from conventional river-based hydro in that: the reservoirs are small hundreds rather than thousands of hectares.
Typically, conventional hydro-electric systems are located in river valleys with lake areas of thousands of hectares and expensive and extensive flood control measures to cope with once-in-ten-thousand-year floods minimal flood control measures are needed because the reservoirs are deliberately placed away from watercourses that have sufficient catchment to cause serious flooding the heads are 2—5 times larger because the upper reservoir can be on top of a hill rather than in a river valley.
An increased head is advantageous because a doubled head allows doubling of energy stored and power developed, while the cost is generally less than doubled and there are minimal environmental impacts because reservoirs are small and river flows are not disturbed.
Energy storage needs A key point in relation to storage in a grid dominated by PV and wind is that a relatively small amount of storage is usually sufficient. Figure 3: distribution of pumped hydro energy storage sites identified by ANU. Image credits: Data 61 and Bing maps Energy storage in pumped hydro The energy storage capability of a pumped hydro energy storage system is the product of the mass of water stored in the upper reservoir in kilograms , the usable fraction of that water, the gravitational constant, the head in metres , and the system efficiency.
