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.

Indian Power SystemElectricity sector in India is growing at rapid pace. During the current year 2016-17 (Up to 31.01.2017),

the Peak Demand is about 159 GW and the Installed Capacity is 314.64 GW.

Transmission SystemDepending 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.

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.

objectives of formation of National Grid

To transfer power from surplus regions to deficit regions.

Utilise maximum resources from diversified regions.

Ensure reliable, economical and quality power.

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.

Global Energy CrisesGlobal 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.

The President’s Message: IndependenceCut 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)

Energy Scenario in IndiaIndia 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).
