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).
What is pumped storage hydropower?
Pumped storage hydropower is the most dominant form of energy storage on the electric grid today. It also plays an important role in bringing more renewable resources onto the grid.

What is the energy storage capacity of a pumped hydro facility?
The energy storage capacity of a pumped hydro facility depends on the size of its two reservoirs.
