Storage capacity needs to be increased around 17-fold by 2050, and AEMO has singled out large-scale pumped hydro as a key strategy in helping to stabilise the grid.
Pumped storage hydropower (PSH) is a type of hydroelectric energy storage. It is a configuration of two water reservoirs at different elevations that can generate power as water moves down from one to the other (discharge), passing through a turbine. The system also requires power as it pumps water back into the upper reservoir (recharge).
Pumped hydro energy storage is the most established technology for utility-scale energy storage for electricity. This technology has been in existence for decades.
