2 introductionHydroelectricity 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.
3 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.

7 CLASSIFICATIONHydro-Electric power plants are classified according to:Availability of water head.Low Head.Medium Head.High HeadType of load they supply.Base Load.Peak Load.
8 Types of turbine Mainly water turbines are of three types: Pelton WheelSpecific Speed – rpm.Head above 200 m.Francis TurbineSpecific Speed – rpm.Head 30 m – 200 m.Kaplan TurbineSpecific Speed – 300 – 1000 rpm.Head less than 30 m.
10 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.
11 disadvantages Requires large area. Initial cost is high. Takes long time for construction of Dam.Requires long transmission lines.Power generation mainly depends on rain.
12 conclusionHydroelectric 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.
