1882 World first hydroelectric power plant began operation on
the fox river (America)
In India first hydroelectric power plant is started in Mysore in 1902
having capacity 4.2 mw
Today About 21% (38106mw)of India & 30% (5000Gw)of world
electricity comes from hydropower
Introduction
In hydropower water is utilized to move turbines which in turn run
the electric generator's
The potential energy of water stored in the dam gets converted
into kinetic Energy of the moving water in the penstock & this
kinetic gets converted into the Electrical Energy with the help of
turbine &generator

ThreeGorges(china)
...22500MW
.It is the first largest hydroelectric power
plant in world….(1993-2012)
Height (181m),&(2035m)long.
.In this used total 32 turbine’s and
each turbine produced700MW,&
Two turbine’s 50MW.
The itaipu (brazil¶guyborder).
...14000MW
.It is second largest
hydroelectric power plant in
world… (1975-1982)
Power generation is started in 1984
ltaipu
.It is used 20 generating unit’s each produce 700MW.
Guripower
(venezuela)…10200
MW
.It is third largest hydroelectric
power plant…(1963-1986)
.It is used 20 generating unit’s,of
different capability ranging
130,770MW.
Tucurui
(brazil)…8370MW
It is the fourth largest hydroelectric power plant of
world.
It is devlop in two phase.is’t phase (1997-1984)&second
phase(1998-2010).
It is 11 Generating unit’s
capability ranging 370MW.
Grandcoulee
(columbia)…6809MW
.It is the fifth largest hydroelectric
power plant in the world.(1933-
1950)
.It is used 18 francis turbine 125MW & three francis turbine 10MW.
India largest hydroelectric
power plant’s1.) The Tehri Dam – is the highest dam in India and tenth tallest
dam in the world. It is a multi-purpose rock and earth-fill embankment
dam on the Bhagirathi River near Tehri in Uttarakhand, India.
Capacity (2400)mw
(1978-2006)
2.) The Koyna Hydroelectric Dam –is the
second largest hydroelectric power plant of
India. The total Installed capacity of the project
is 1,960 MW. Near Patna ,satara district
(koynanagar) (1962 -1981)
DAMA Dam is barrier, which confines or raise water for storage
Diversion to create a hydraulic head
Generally made of concrete,rockfill or timber
Penstock
Penstock is the connecting pipe between the dam &the
turbine house.
It helps to increase the kinetic energy of water coming from
the dam.
Penstock is made up of a very strong material. steel, ductile
iron or polyethylene.
Turbine &Generator(T-G)Combination
Turbine: Turbine is a very light fan like structure having many number of blades.it has an ability to rotate on its axis when water passes through it.
Generator: It is a device in which when there is rotation of coil between
The strong magnetic Field than it produces an Alternating current.
ADVANTAGE’SMaintenance & operation charges are very low.
Running cost is very low.
Plant efficiency does not changes with age.
Long life in comparison with the thermal& Nuclear power plant.
No fuel charges
DISADVANTAGE’S
Initial cost is very high
Takes long time for construction
Plant’s are located in hilly area’s
Long transmission line is required
