8. In January 2016, the installed power generation capacity of India stood at 2, 84,303
MW.
The per capita energy consumption stood at 1010 KWhr (2014-15).
India is the fifth largest in terms of power generation.
About 69.8% of the electricity consumed in India is generated by Thermal power
plants, 15% by Hydroelectric power plants and 2.0% by Nuclear power plants and
rest of 13.2% from other Renewable Energy Sources.
Other than PSUs and state level corporations, private sector enterprises also play a
major role in generation, transmission and distribution, about 39.5%
(1,12,207MW) of total installed capacity is generated by private sector.
India’s electricity generation has been growing continuously to meet the necessities
of the rapidly rising economic activity of the country.

15. • Transmission forms a critical link in the power sector value chain.
India's power generation capacities are unevenly dispersed across the
country creating an imbalance between the distribution of power
demand and supply centres.
• The country has been demarcated into five electrical Regions:
Northern (NR)
Eastern (ER)
Western (WR)
Southern (SR)
North Eastern (NER)
• All the regional grids are synchronously interconnected and operating as
single grid known as Central Grid or National Grid.

34. Thermal power plants convert energy rich fuel into
electricity and heat. Possible fuels include coal, natural
gas, petroleum products, agricultural waste and domestic
trash / waste.
• Coal and lignite accounted for about 67% of India's
installed capacity.
• India's electricity sector consumes about 80% of the coal
produced in the country. A large part of Indian coal
reserve is similar to Gondwana coal.
35.
36. Thermal power plants can deploy a wide range of technologies.
Some of the major technologies include:
• Steam cycle facilities (most commonly used for large utilities);
• Gas turbines (commonly used for moderate sized peaking
facilities);
• Cogeneration and combined cycle facility (the combination of
gas turbines or internal combustion engines with heat recovery
systems); and
• Internal combustion engines (commonly used for small remote
sites or stand-by power generation).
39. NUCLEAR POWER
Nuclear power is the fourth-largest source of electricity in India after thermal, hydroelectric and renewable sources of
electricity. As of 2012, India has 20 Nuclear reactors in operation in six nuclear power plants, having an installed capacity of
4780 MW and producing a total of 29,664.75 GWh of electricity while seven other reactors are under construction and are
expected to generate an additional 6,100 MW.
India's first research nuclear reactor and its first nuclear power plant were built with assistance from Canada. The 40 MW
research reactor agreement was signed in 1956, and achieved first criticality in 1960
There are two nuclear corporation in india
1. The Nuclear Power Corporation of India Limited (NPCIL) is a government-owned corporation of India based
in Mumbai. NPCIL was created in September 1987.Nuclear Power and electricity generation and distribution
2. The Bharatiya Nabhikiya Vidyut Nigam Limited(BHAVINI) is a government-owned corporation of
India based in Chennai. Bhavini was established on 2004.Nuclear Power and electricity generation and distribution
• India has a flourishing and largely indigenous nuclear power program and expects to have 14,600 MWe nuclear capacity on
line by 2020. It aims to supply 25% of electricity from nuclear power by 2050.
• Because India is outside the Nuclear Non-Proliferation Treaty due to its weapons program, it was for 34 years largely
excluded from trade in nuclear plant or materials, which has hampered its development of civil nuclear energy until 2009.
• Due to these trade bans and lack of indigenous uranium, India has uniquely been developing a nuclear fuel cycle to exploit
its reserves of thorium.

44. • Hydropower is a renewable, non-polluting and environment friendly source of energy.
Oldest energy technique known to mankind for conversion of mechanical energy into
electrical energy. Contributes around 22% of the world electricity supply generated .
• In India, Jamshed ji Tata built the first hydroelectric power dam in the Western Ghats of
Maharashtra in the early 1900s to supply power to Bombay’s Cotton and Textile Mills
• Out of the total power generation installed capacity in India of 2,48,509.64MW (June,
2014), hydro power contributes about 16% i.e. 40661.41 MW. The total hydroelectric
power potential in the country is assessed at about 150,000 MW, equivalent to 84,000 MW
at 60% load factor. The potential of small hydro power projects is estimated at about 15,000
MW.
• As per assessment made by CEA, India is endowed with economically exploitable hydro-
power potential to the tune of 1 48 700 MW of installed capacity. The basin wise assessed
potential is as
45. SOLAR ENERGY
• India is bestowed with solar irradiation ranging from 4 to 7 kWh/square
meter/day across the country, with western and southern regions having higher
solar incidence.
• India is endowed with rich solar energy resource. India receives the highest
global solar radiation on a horizontal surface.
• Government of India launched its Jawaharlal Nehru National Solar Mission.
• The first Indian solar thermal power project (2X50MW) is in progress in
Phalodi Rajasthan.
• Land acquisition is a challenge to solar farm projects in India.
• exploring means to deploy solar capacity above their extensive irrigation
canal projects, thereby harvesting solar energy while reducing the loss of
irrigation water by solar evaporation

49. GEO-THERMAL ENERGY
• India's geothermal energy installed capacity is experimental. Commercial
use is insignificant.
• India has about 340 hot springs spread over the country. Of this, 62 are
distributed along the northwest Himalaya, in the States of Jammu and
Kashmir, Himachal Pradesh and Uttarakhand
• .
• Andaman and Nicobar arc is the only place in India where volcanic activity
geo-thermal energy is present.
• India plans to set up its first geothermal power plant
• Tattapani in Chhattisgarh
• Puga in Jammu & Kashmir
• Cambay Graben in Gujarat
• Manikaran in Himachal Pradesh

51. TIDAL WAVE ENERGY
• India is surrounded by sea on three sides, its potential to harness tidal
energy is significant.
• The Gulf of Khambhat and the Gulf of Kutch on India's west coast where
the maximum tidal range is 11 m and 8 m with average tidal range of 6.77
m and 5.23 m respectively AND 4m is sufficient.
• Barrage technology could harvest about 8 GW from tidal energy in India,
mostly in Gujarat.
• Potential along the Indian coast is between 5 MW to 15 MW per
meter, suggesting a theoretical maximum potential for electricity
harvesting from India's 7500 kilometer coast line may be about 40

58. Distribution and Retail Supply is the most critical link in the electricity market, which interfaces
with the end customers and provides revenue for the entire value chain.
Indian electricity distribution caters to nearly 200 million consumers with a connected load of
about 400 GW that places the country among the largest electricity consumer bases in the world
.
• The consumers are served by around 73 distribution utilities
13 electricity departments,
17 private distribution companies,
41 corporatized distribution companies
2 State Electricity Boards
• Rural distribution segment in India is characterized by wide dispersal of net work in large
areas with long lines, high cost of supply, low paying capacity of the people, large number of
subsidized customers, un-metered flat rate supply to farmers, non metering due to high cost and
practical difficulties, low load and low rate of load growth. Consumer mix in rural areas is mainly
agriculture and residential.
• Urban distribution is characterized by high consumer density, and higher rate of growth of
load. The consumer mix in urban areas is mostly commercial, residential, and industrial.
Both segments are distinct with different problems and issues.

67. Power trading inherently means a transaction where the price of power is negotiable and options
exist about whom to trade with and for what quantum. In India, power trading is in an evolving
stage and the volumes of exchange are not huge. All ultimate consumers of electricity are largely
served by their respective State Electricity Boards or their successor entities, Power Departments,
private licenses etc. and their relationship is primarily that of captive customers versus monopoly
suppliers. In India, the generators of electricity like Central Generating Stations
(CGSs).Independent Power Producers (IPPs) and State Electricity Boards (SEBs) have all their
capacities tied up. Each SEB has an allocated share in central sector/ jointly owned projects and
is expected to draw its share without much say about the price. In other words, the suppliers of
electricity have little choice about whom to sell the power and the buyers have no choice about
whom to purchase their power from.
68. India’s Energy uses and emissions are low compared to industrialized
countries…. BUT
We need to search for Sustainable development options for India, quickly due
to factors like
Constraints on energy use, arising from
(a) limited domestic energy resources,
(b) climate constraints, and
(c) land, water and social issues related to energy projects
CONCLUSION
