INTRODUCTION
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.

HYDRO POWER PLANT IN
INDIA

First Hydro Power Plant was constructed at
Mysore in 1902 named as “ SHIVANASAMUDRA
” having capacity 4.5 MW.

Second Hydro Power Plant was constructed at
Maharashtra in 1914 named as “ KHOPOLO ”
having capacity 50 MW.

The present installed capacity is 37,367 MW;
21.53% of total Electricity Generation in India.

CLASSIFICATION
Hydro-Electric power plants are classified according to:
Availability of water head.
 Low Head.
 Medium Head.
 High Head
 Type of load they supply.
 Base Load.
 Peak Load.

TYPES OF TURBINE
Mainly water turbines are of three types:
 Pelton Wheel
 Specific Speed – 10-50 rpm.
 Head above 200 m.

Francis Turbine
 Specific Speed – 60-300 rpm.
 Head 30 m – 200 m.

Kaplan Turbine
 Specific Speed – 300 – 1000 rpm.
 Head less than 30 m.
THE THREE GORGES DAM, CHINA (22,500 MW)
ADVANTAGES

No fuel charges.

Maintenance & operation charges are very low.

Running cost of the plant is low.

The plant efficiency does not changes with age.

Takes few minutes to run & synchronize the plant.

No fuel transportation is required.

No Pollution.

Used for flood control & irrigation purpose.

Long life.
DISADVANTAGES
 Requires
large area.
 Initial
cost is high.
 Takes
long time for construction of Dam.
 Requires
 Power
long transmission lines.
generation mainly depends on rain.
CONCLUSION
Hydroelectric power was one of the first renewable
sources of energy, and therefore the most developed
currently.
 Overtime other renewable sources of energy will
develop and become competitive, offering a wider
variety of affordable renewable energy.
 Hydroelectric’s market growth in the United States
seems to have reached a plateau and is unlikely to see
significant growth in the future.
