This system requires power to pump water back into the upper reservoir (i.e. to recharge) and used for load balancing. During periods of low demand of electricity surplus electrical energy is used to pump water back into upper reservoir and store it. Similarly during periods of high demand of electricity, the stored water is released through turbines to produce electricity.
PSH uses reverse turbines which can operate as turbine during discharge while generating electricity and can also function as pump during recharge to move water to the upper reservoir from lower reservoir. PSH acts as a giant battery as it can store electrical power and use when needed.
