Pumped storage facilities are used as a means of storing electricity. When demand is high the unit is used to generate electricity, and when demand is low or excess supply is available, electricity is used to pump water back uphill. Over time, pumped storage facilities are net consumers of power since it takes electricity to pump the water ...
