How do pumped storage power plants work?

Pumped-storage power plants store electricity using water from dams. The new model for using the plants in combination with renewable energy has led to a revival of the technology. In 2000, there were around 30 pumped storage power plants with a capacity of more than 1,000 megawatts worldwide.

Energy storage

Storage capacity is the amount of energy extracted from an energy storage device or system; usually measured in joules or kilowatt-hours and their multiples, it may be given in number of hours of electricity production at power plant nameplate capacity; when storage is of primary type (i.e., thermal or pumped-water), output is sourced only with
