3.  Introduction:
 Hydropower is electrical energy produced through
the power of moving water.
 Hydropower is a type of renewable energy, and
once the power plant is constructed it produces little to
no waste.
 China is the largest hydroelectricity producer.
 India is the 7th largest producer of hydroelectric
power in the world. In 2014 and 2015, the total amount
of hydropower generation in India 129 TWh.

4. •History of hydro power plant:
•First hydro power is used by the Greeks to spin water
wheels for crushing wheat into flour before more than
2000 years ago.
•
•We start to generate electricity from hydro power in 1882
when United States (U S) establishes a first hydro power
station which generate 12.5 kilowatts (KW) of power.
•In between 1905-1911 largest hydro power station
(Roosevelt Dam) is built by the united state and its
generated capacity is increased from 4500 kW to 36,000
kW.
•first hydro power station, capacity of 130kW establishes in
Asia at mounts of Darjeeling in 1898 and after that in
1902 Shimsh (Shivanasamudra) is established and both
located in India.

5. WHY HYDROELECTRIC PLANT
 Renewable and non polluting source of energy.
Best choice for meeting the peak demand.
Longer useful life and help in conserving sources
fossil fuels.
 Storage based hydro-project after incidental
benefits like irrigation , flood water supply in land
water.
Help in opening up of avenues for developed of
remote backward.

•Oil Water System

8. GENERATOR
 Water flow
through multiple
gates to many
turbine-blades
generate enough
mechanical power to
rotate water turbine
coupled with
Generator through a
shaft as shown
opposite

10. FRANCIS TURBINES
A turbines is the vertical shaft ,Francis type ,directly coupled to
generator. The spiral casing is suitable cross section fabricated
from steel plates.

11. ADVANTAGES
The major advantage of hydroelectricity is elimination of
the cost of fuel.
Multi-use dams installed for irrigation support agriculture
with a relatively constant water supply.
Large hydro dams can control floods, which would
otherwise affect people living downstream of the project.
In some countries, aquaculture in reservoirs is common.

12. DISADVANTAGES
Due to high cost of civil engineering works
, the capital cost per KW of hydro plant is
high.
Since hydro plant entails huge civil
engineering works ,they take a considerably
long for completion.
 hydro power generation is dependent on
availability of water. In a dry year , the
power generation is very low.
