IMPORTANCE

The importance of generating power

through hydel resources is increasing

day by day as the generating costthermal plants is increasing rapidly.

In addition to this, there are many

problems associated with thermal plantlike coal mining, cleaning, transportation

and storage.


3/17

Conventional sourcesinclude: firewood,

cattle dung cake, coal,petroleum, natural

gas and electricity (both hydel andthermal).

Non-conventional sources include solar,

wind, tidal, geothermal, biogas and atomicenergy.

Energy resources are the chief sources of

fuel and power in India.

THERE ARE THREE TYPES OF

HYDROPOWER FACILITIES

Impoundment

Diversion

Pumped storage

Some hydropower plants use dams and

some do not. The images below show

both types of hydropower plants

IMPOUNDMENT

The most common type of hydroelectricpower plant is an impoundment facility.

An impoundment facility, typically a large

hydropower system,

Uses a dam to store river water in a

reservoir. Water released from the

reservoir flows through a turbine,

spinning it, which in turn activates a

generator to produce electricity.

PUMPED STORAGE

Another type of hydropower called pumped

storage works like a battery It stores energy by pumping water up hill to a

reservoir at higher elevation from a second

reservoir at a lower elevation.

When the demand for electricity is low, a

pumped storage facility stores energy by

pumping water from a lower reservoir to an

upper reservoir. During periods of high electrical demand, the

water is released back to the lower reservoir and

turns a turbine, generating electricity.

SIZE OF HYDROELECTRIC

POWER PLANTS

Facilities range in size from large power

plants that supply many consumers with

electricity to small and micro plants thatindividuals operate for their own energy

needs or to sell power to utilities


14/17

LARGE HYDRO POWER

Although definitions vary, Its defineslarge hydropower as facilities that have a

capacity of more than 30 megawatts.

SMALL HYDRO POWER

Although definitions vary, Its defines

small hydropower as facilities that have acapacity of 100 kilowatts to 30

megawatts.


15/17

MICRO HYDRO POWER

A micro hydropower plant has a capacity

of up to 100 kilowatts. A small or micro-

hydroelectric power system can produceenough electricity for a home, farm,

ranch, or village.
