Pumped Storage Systems
PRINCIPLES OF PUMPED STORAGE Pumped storage schemes store electric energy by pumping water from a lower reservoir into an upper reservoir when there is a surplus of electrical energy in a power grid. During periods of high energy demand the water is released back through the turbines and electricity is generated and fed into the grid.
