2.  Energy in the form of electricity is now
one of the basic necessities of life.
 Though deficiency in oil and
gas, Pakistan has abundant water and
other energy sources like Hydel
power, coal and solar power.
 Hydel power provides about 34 percent
of the renewable energy in Pakistan.

3.  Hydroelectric power plants do not use
up resources to create electricity nor do
 they pollute the air
 Land
 water
 as other power plants may.

4.  No Fuel is required to run the plant
 No air-pollution is created
 Has a longer life
 No change in efficiency with the age
 Hydraulic turbines can be started
speedily
 Cost of power per unit is very less

8. How Hydel power
plants work?

9.  Water, when it is falling by the force of
gravity, can be used to turn turbines and
generators that produce electricity.
 When the electricity is generated from
the power plant it is transmitted by
power lines or cables to the homes.

10.  Reservoir-this is where water is stored for
use as needed.
 Water Turbine-used to convert hydraulic
energy of flowing water into rotational
mechanical energy.
 Penstock-is a conduit which carries
water into the turbines.
 Generator-it is used to convert rotational
mechanical energy into electrical
energy

13. Some of the major and known Hydel
power projects are as follows:

15.  It’s build on Indus at Bara near village
Tarbela.
 It’s the world largest earth filled dam.
 The dam was completed in 1976 at a
cost of Rs.18.5 billion.
 It’s 143 km high and a reservoir area of
243 square km.
 With a storage capacity of 119 billion
cubic meters of water.

17.  It’s located on the River Jhelum.
 It’s one of the longest earth filled dam in
the world.
 The main structures of the dam include
4 embankment, 2 spillways, 5 power
irrigation tunnels and a 1,000 MW power
station.
 It’s a multipurpose project to control
flood water and generate HEP.
