Pumped hydro storage is the only large energy storage technique widely used in power systems. For decades, utilities have used pumped hydro storage as an economical way to utilise off-peak energy, by pumping water to a reservoir at a higher level. During peak load periods the stored water is discharged through the pumps, then acting as turbines, to ...

Pumped-storage hydroelectricity
2014World-wide efforts to reduce emissions of climate gasses have led many countries to pursue a policy of increasing the share of renewable energy in order to move away from a carbon-based generation of electricity. Renewables, like wind power, solar and small-scale hydro power, are intermittent and uncontrollable and therefore needs other generating ...

Symposium on Pumped Storage: American Pumped Storage Equipment and Operation
Journal of the Power Division, 1962The applications of pumped-storage hydroelectric power in North America, with particular regard to reversible pump-turbines, is described. Problems in starting and operation are described and information necessary for making the proper selection of capacity and speed is given.

Proceedings of the Institution of Electrical Engineers, 1975
The Foyers pumped-storage scheme is the second in the United Kingdom to use reversible pump turbines and the first shaft-type station. The paper shows how the requirements of the power system and the characteristics of the site influenced the design parameters and describes the various engineering and costing studies which were undertaken in arriving ...

Pumped hydro storage is analogous to the operation of a massive battery, capable of storing hundreds of megawatts of energy in a simple and sustainable manner. Hydrogeneration projects are strategic in nature and always involve an investment on a national scale.

Quarterly Journal of Engineering Geology, 1971
Pumped storage projects involve major civil engineering works costing tens of millions of pounds but are nevertheless an efficient way of storing energy and economically a better method of meeting peak loads than building bigger generating stations. Because they require special environments, reservoirs for pumped storage raise difficult problems in ...

Ludington Pumped Storage Project
Journal of the Power Division, 1973The Ludington pumped storage project, when completed at the end of 1973, will have a 1,872-Mw installed capacity. The upper reservoir with 53,000 acre-ft usable vessel is formed by a 6-mile long earth-fill dam with a sandwich type asphalt facing. The six penstocks are encased in concrete, under the embankment, and buried in silty sand on the slope.
