WEBA hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand.
Types of Hydropower Plants - Department of Energy
WEBThere are three types of hydropower facilities: impoundment, diversion, and pumped storage. Some hydropower plants use dams and some do not. Although not all dams were built for hydropower, they have proven useful for …
Hydroelectric power | Definition, Renewable Energy, Advantages ...
WEBHydroelectric power is a form of renewable energy in which electricity is produced from generators driven by turbines that convert the potential energy of moving water into mechanical energy. Hydroelectric power plants usually are located in dams that impound rivers, though tidal action is used in some coastal areas.

WEBHydropower technologies generate power by using the elevation difference, created by a dam or diversion structure, of water flowing in on one side and out, far below, on the other.
Hydroelectric dam - Energy Education
WEBA hydroelectric dam is one of the major components of a hydroelectric facility. A dam is a large, man-made structure built to contain some body of water. In addition to construction for the purpose of producing hydroelectric power, dams are created to control river flow and regulate flooding.
