5.5: Pumped Storage Hydroelectric Plants (PSHP)
One great advantage of hydropower technology is that it makes it possible to build plants in which large amount of energy can be stored and used later “on demand”. Such complexes are called “pumped

Pumped Water Energy Storage
The excess power at low demand periods is used to pump water from a lower reservoir to a higher reservoir. Later, when needed, the potential energy stored in the upper reservoir is recovered as
