2. WHAT IS POWER PLANT?
 A power plant is an industrial facility that generates
electricity from primary energy. Most power plants use one or
more generators that convert mechanical energy into electrical
energy in order to supply power to the electrical grid for
society's electrical needs. The exception is solar power plants, which
use photovoltaic cells (instead of a turbine) to generate this electricity.

3. TYPES OF POWER PLANTS
 Nuclear power plants. ...
 Hydroelectric power plants. ...
 Coal-fired power plants. ...
 Diesel-fired power plants. ...
 Geothermal power plants. ...
 Gas-fired power plants. ...
 Solar power plants. ...
 Wind power plants.

4. HYDROPOWER PLANTS
 Hydropower, or hydroelectric power, is a
renewable source of energy that
generates power by using a dam or
diversion structure to alter the natural
flow of a river or other body of water.

5. HOW HYDROPOWER PLANT
WORKS?
 At hydropower plants water flows through
a pipe, or penstock, then pushes against
and turns blades in a turbine to spin a
generator to produce electricity.
Conventional hydroelectric facilities include:
Run-of-the-river systems, where the force of
the river's current applies pressure on a
turbine.

6. HOW MANY HYDROPOWER
PLANTS DOES INDIA HAVE?
 As of December 2022, India has 197 total
operational hydroelectric power
plants producing 46,850 MW. However, the
seven largest hydroelectric power plants
generate a quarter of this power. The
subsequent sections list India's seven largest
hydroelectric power projects as of July 2022.

7. TEHRI HYDROPOWER COMPLEX
– 2,400MW
 the Tehri Dam in Uttarakhand, the highest
hydroelectric power project in the country.
Commissioned in 2006, first construction began in 1978
helped by technical collaboration from the former USSR.
 Located at the confluence of the Bhagirathi and the
Bhilangana rivers, near the city of Tehri, the dam is a
multi-purpose rock and earth-filled embankment dam,
and at 260.5 metres is the tallest in India.

8. KOYNA HYDROELECTRIC PROJECT
– 1,960MW
 Located near Patan, in Maharashtra’s Satara district, close
to the Koyna River, the Koyna Hydroelectric Project is India’s
largest completed hydroelectric power plant with a capacity of
1,960MW.
 Owned and operated by MAHAGENCO and
Maharashtra State Power Generation, the Koyna Project has
four dams, the largest of which is constructed across the
Koyna River.
 As the dam is located in the Western Ghats mountain
range, all the generators of the power plant have been
installed deep inside the mountains requiring extensive
excavation works.

9. SARDAR SAROVAR DAM
-1,450MW
 The largest dam of the Narmada Valley Project, Sardar
Sarovar Dam supplies water and electricity to four Indian
states—Gujarat, Maharashtra, Rajasthan and Madhya
Pradesh.
 Although the foundation stone was laid in 1961, the
project began to take form in 1979 with the help of a
World-Bank funded development scheme, and
construction began in 1987.
 Environmental opposition stalled construction efforts,
and the dam was finally inaugurated in 2017.

10. THERMAL POWER PLANTS
 A thermal power station is a type
of power station in which heat energy is
converted to electrical energy. In a steam-
generating cycle heat is used to boil water in
a large pressure vessel to produce high-
pressure steam, which drives a steam
turbine connected to an electrical generator.

11. HOW THERMAL POWER
PLANT WORKS?
 The burning of fuels such as oil,
coal and LNG (liquefied natural gas)
fires a boiler to generate high-
temperature, high-pressure
steam. This steam is used to drive a
steam turbine. A generator attached to the
steam turbine generates electricity.

12. HOW MANY THERMAL POWER PLANT
DOES INDIA HAVE ?
 As of now, there are 106 thermal power
plants in India with a total installed capacity
of 221,802.59 MW. Of these 106 plants, 53
are coalfired, 24 are gasfired, 11 are oilfired,
nine are mixed fuelfired and the remaining
two use renewable sources – solar and
biomass.

13. FARIDABAD THERMAL POWER
PLANT
 Faridabad Combined Cycle Gas
Power Plant or NTPC Faridabad is
located at Faridabad, in Faridabad district in
the Indian state of Haryana. The power
plant is one of the gas-based power plants
owned by NTPC. The gas for the power
plant is sourced from GAIL HBJ Pipeline.
Source of water for the power plant is
Rampur distributories of Gurgaon canal.

14. VINDHYACHAL THERMAL POWER
STATION
The Vindhyachal Thermal Power
Station in the Singrauli district of Madhya
Pradesh, with an installed capacity of
4,760MW, is currently the biggest thermal
power plant in India. It is a coal-based
power plant owned and operated by
NTPC.

15. MUNDRA THERMAL POWER
STATION
 The 4,620MW Mundra Thermal
Power Station located in the Kutch
district of Gujarat is currently the
second biggest operating thermal
power plant in India. It is a coal-fired
power plant owned and operated
by Adani Power .
