INTRODUCTION One of the most widely used renewable source of energy

for generating electricity on large scale basis is hydropower

The power obtained from river or ocean water is called as hydropower

In Hydro Power Plant the Water is utilized to move the Turbines which in turn run the Generator’s.

The Potential energy of the water stored gets converted into the Kinetic Energy of the moving water which gets converted into the Electrical Energy with the help of Turbines & Generators

HISTORY

Nearly 2000 years ago the Greeks used water wheels to grind wheat into flour

Appleton, Wisconsin became the first operational hydroelectric generating station in the United States, in 1882, producing 12.5 kilowatts (kW) of power .

In India, First Hydro Power Plant was constructed at Darjeeling in 1898 named as “ SINDRAPONG ” having capacity 130kW.

Contd . . . Second Hydro Power Plant was constructed at Mysore in

1902 named as “ SHIMSHA ” having capacity of 17.2 MW.

China is the largest hydroelectricity producer, with 721 terawatt-hours of production in 2010.

Three Gorges Dam in China producing 22,500 MW is the largest dam in the world.

ENERGY SCENARIOs Hydropower is produced in 150 countries, with the Asia-Pacific

region generating 32 percent of global hydropower in 2010

Widely used form of renewable energy, accounting for 16 percent of global electricity generation – 3,427 terawatt-hours of electricity production in 2010

Only three facilities are over 10 GW (10,000 MW) are in operation worldwide; Three Gorges Dam at 22.5 GW, Itaipu Dam at 14 GW, and Guri Dam at 10.2 GW.

Total world small-hydro capacity is 85 GW. Over 70% of this was in China (65 GW), followed by Japan (3.5 GW), the United States (3 GW), and India (2 GW).

ADVANTAGES

1) No fuel required

2) Cost of electricity is constant

3) No air-pollution is created

4) Long life

5) Cost of generation of electricity

6) Irrigation of farms

DISADVANTAGES

1) Disrupts the aquatic ecosystems

2) Disruption in the surrounding areas

3) Requires large areas

4) Very high capital cost or investment

5) High quality construction

6) Site specific

7) Safety of the dams
