Schematic diagram of a pumped hydro storage system. The potential energy stored by water is converted into electricity at convenient time. . [...] Driven by global concerns about the climate and the environment, the world is opting for renewable energy sources (RESs), such as wind and solar.
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.
To accommodate load changes that occur within the power system and to maintain constant speed, hydraulic and pumped storage plants rely on an assortment of devices. These control elements include movable gates and runners as well as a speed governor system that regulates the flow, power output, and speed to match the system demand.
The two reservoirs, an upper and a lower, together form a pumped-storage power system. Pumped-storage power plants are structured around two bodies of water, an upper and a lower reservoir 1 (see the diagram below).
Indeed, if the turbine is in a base-loaded plant and the power output of the plant is adjusted to meet the demands of the available head, the plant would be able to operate year-round at a constant efficiency of 91%. Pumped storage plants would realize an additional payoff in efficiency if the variable-speed operation were adopted.
In this pumping cycle case, generator/turbine assembly works as pump/motor. When there’s a sudden demand for power, the “head gates” are opened, and water rushes down the tunnels to drive the turbines, which drive the powerful generators. This is called generation cycle.

How They Work: Pumped-Storage Power Plants
Pumped-storage power plants are structured around two bodies of water, an upper and a lower reservoir 1 (see the diagram below). At times of very high electricity consumption on the grid, the water from the upper reservoir, carried downhill by a penstock, drives a turbine and a generator to produce electricity, which is used to meet the ...
