What is pumped storage hydropower?

In pumped storage hydropower, previously generated electricity is converted to potential energy when pumped uphill and stored in the form of water at an upper elevation (reservoir), where it later flows downhill to a lower reservoir through turbine and converted back to electricity.

What is a pumped Energy System?

Pumped schemes energy by pumping water from a lower reservoir into an upper reservoir when there is a surplus of electrical energy in a power grid. the grid. They play an important role as they absorb energy from the system in periods with excess energy, and generate electricity when energy demand is high or a generator fails in the system.
