WHAT is HYDRO POWER? Hydroelectricity is the term referring to electricity generated by hydropower; the production of electrical power through the use of the gravitational force of falling or flowing water. It is the most widely used form of renewable energy. Once a hydroelectric complex is constructed, the project produces no direct waste, and has a considerably lower output level of the greenhouse gas carbon dioxide (CO2) than fossil fuel powered energy plants. In hydrology , hydropower is manifested in the force of the water on the riverbed and banks of a river. It is particularly powerful when the river is in flood. The force of the water results in the removal of sediment and other materials from the riverbed and banks of the river, causing erosion and other alterations.

Historically… Pumped hydro was first used in Italy and Switzerland in the 1890's. By 1933 reversible pump-turbines with motor- generators were available Adjustable speed machines now used to improve efficiency Pumped hydro is available at almost any scale with discharge times ranging from several hours to a few days. Efficiency = 70 – 85% 33 http://www.electricitystorage.org/tech/technologies_technologies_pumpedhydro.htm

The potential is about 84000 MW at 60% load factor spread across six major basins in the country. Pumped storage sites have been found recently which leads to a further addition of a maximum of 94000 MW . Annual yield is assessed to be about 420 billion units per year though with seasonal energy the value crosses600 billion mark. The possible installed capacity is around 150000 MW
