The document provides an overview of the Indian power system, including its generation, transmission, and distribution. Some key points: - India's peak power demand is around 159 GW with total installed capacity of 314.64 GW as of 2017. Thermal sources account for 69% of installed capacity. - The transmission system includes 765 kV, 400 kV, 220 kV, 132kV lines to transfer power across regions. A national grid was established to optimize resource utilization. - Distribution systems distribute power at lower voltages like 66 kV and 33 kV to end consumers. Rural electrification programs aim to expand access across India.

2. Energy : The Building Block of Economy
Energy is essential for Economic growth.
Economic growth is essential for country like India.
Ratio of energy demand and GDP is useful indicator for
Economics growth.
Economic growth of country is depend upon rate of
improvement in per capita energy consumption.

8. Transmission System
Depending upon the quantum of power and the distance
involved, lines of appropriate voltages are laid.
765 kV, 400 kV,220 kV, 132kV, 66 kV and 33 kV AC
lines.
As on 31st
December’ 2016, the total transmission
capacity of the inter-regional links is 63,650 MW, which
is expected to be increased to 68,050 MW by the end of
12th plan i.e. 31st
March, 2017.

10. Distribution system
That part of power system which distributes electric
power for local use is known as distribution system.
In general, the distribution system is the electrical system
between the sub-station fed by the transmission system
and the consumers meters.

Government of India has launched the scheme “Deendayal Upadhyaya
Gram Jyoti Yojana” for rural electrification.
Rural Electrification Corporation is the Nodal Agency for
implementation of DDUGJY.
Under DDUGJY-RE, Ministry of Power has sanctioned 921 projects
to electrify 1,21,225 un-electrified villages.

19. Global Energy Crises
Global Energy requirement increases continuously.
Fuel resources are depleted.
Oil price increase continuously.
It put pressure on country economic.
It is estimated that in next 50-60 year oil & gas
resources are consumed.

20. The President’s Message: Independence
Cut down energy losses.
Utilize technologies to provide
a diverse supply of
environmentally friendly
energy.
“We must achieve Energy
Independence by 2030”,
including a cut down in ALL
sectors.
Increase the power generated
through renewable energy
sources from 5% to 25%.
This is the nation’s “first and
highest priority”.
President A.P.J. Abdul Kalam
(Rocket Scientist)

21. Energy Scenario in India
India is a seventh largest country and have a
population of 1.2 billion people.
To maintain growth rate, need rapid growth in energy
sector.
Potentially, one of the largest power markets in the world.
Large pool of highly skilled technical personnel.
Abundant coal reserves (enough to last at least 200 years).
