What is pumped storage hydropower (PSH)?
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).
How does a pumped storage hydropower system store electrical energy?
Pumped storage hydropower systems store excess electrical energy by harnessing the potential energy stored in water. Fig. 1.3 depicts PSH, in which surplus energy is used to move water from a lower reservoir to a higher reservoir.
Why do hydropower stations use reservoir storage?
In operations, hydropower stations utilize their own reservoir storage to redistribute uneven inflows over periods of years, months, weeks, days or hours, thereby controlling when and how much electricity is generated. This ability enables them to quickly respond to the increasing demand for flexible power in electrical grids 2, 3.
What is a storage hydropower plant?
Storage hydropower plants include a dam and a reservoir to impound water, which is stored and released later when needed. Water stored in reservoirs provides flexibility to generate electricity on demand and reduces dependence on the variability of inflow.
Should hydropower stations be renovated with pumped storage?
The costs and operational efficiencies of renovating conventional hydropower stations with pumped storage are two key factors that must be considered.
What is the total installed pumped storage hydropower capacity?
According to IHA's 2024 World Hydropower Outlook, total installed pumped storage hydropower (PSH) capacity grew by 6.5GW to 179GW. In addition, pumped hydro enjoys several distinct advantages over other forms of energy storage due to its long asset life, low-lifetime cost and independence from raw materials.
