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.
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.
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.
Such complexes are called โpumped storage plantsโ. In the area of energy storage, they are definitely the record-keepers.
