When there is not much demand for electricity, such as during the night, the extra electricity is used to pump water back up to a storage reservoir. Then, later in the day, when electricity demand is high, the water from the storage water is also released as an extra, producing more electricity when it is needed.
The method stores energy in the form of gravitational potential energy of water, pumped from a lower elevation reservoir to a higher elevation.

When there is not much demand for electricity, such as during the night, the extra electricity is used to pump water back up to a storage reservoir. Then, later in the day, when electricity demand is high, the water from the storage water is also released as an extra, producing more electricity when it is needed. We need them because demand for electricity fluctuates (goes up and down) and pumped storage reservoirs allow us to meet the demand.
George Bransby Williams has written: 'Storage reservoirs' -- subject(s): Dams, Reservoirs, Water-storage
the first ever pumped storage power plant was in taum sauk in ozark highlands , just east of the black river in missouri.
The first pumped storage power plant is considered to be the 1928 Ludington Pumped Storage Power Plant in Ludington, Michigan, USA. It was designed to help stabilize the electrical grid by storing excess power during low demand periods and releasing it during peak demand periods.
Some alternatives to batteries for energy storage include supercapacitors, flywheels, pumped hydro storage, compressed air energy storage, and thermal energy storage.
reservoirs and water storage tanks and towers, typically
The same place as other countries.... from the sky ! The water is collected in a number of reservoirs around the UK, where it's stored until needed. It's then pumped to a water treatment plant, where it's cleaned, sterilized and pumped into the mains network.
it reduces the fluctuation of power station such as in voltage.frequency etc.

Reservoirs are typically filled by surface water sources, such as rivers, streams, and rainfall, rather than water rising up from the earth. While groundwater can contribute to some water bodies, reservoirs primarily rely on inflows from precipitation and runoff. Additionally, some reservoirs may be supplemented by water pumped from underground aquifers, but this is not the same as rising from the earth naturally.
