• Biomass power generation in India is an industry that
attracts investments of over INR 600 crores every year,
generating more than 5000 million units of electricity and
yearly employment of more than 10 million man-days in
the RURAL areas.
53. TRANSMISSION AND DISTRIBUTION
• INDIA is a energy deficient state, with almost
400 million people without electricity which
equals the combined population of u. s .a and
germany.
• The density of distribution is not equal and is
unequal .Thus, to overcome this problem an
interconnected grid system is used so that on
the basis of demand ,supply could be
managed and easily delivered to areas far
away from generating units.
54. THERE ARE 5 GRIDS IN INDIA:
• 1. Northern Grid
• 2. Southern Grid ( not connected with other
grids)
• 3. Western Grid
• 4 . Eastern Grid
• 5. North- Eastern Grid
57. TRANSMISSION AND DISTRIBUTION
LOSSES
• Total distribution and transmission accounts for
23% in INDIA.
• In DELHI losses are as high as 50%.
• The proliferation of Low Tension (L.T) distribution
lines has led to a low load density (as measured
by demand in MW divided by length of T& D
system) and high ratio of LT to HT lines.
• Equal investment as to generation can reduce
transmission and distribution losses.
• Flatten load curve prices
62. RURAL ELECTRIFICATION
• Six decades after Independence, India’s villages
are groping in the dark — literally.
• One-third rural areas have no electricity.
• Situation is particularly bad in india’s cow belt.
• Bihar-25%,jharkhand-43%, orissa- 45%, u.p- 38%.
• China on other hand way back in 1991 has 92%
electricity in rural areas .
• Gujarat and goa has 100% rural electrification
and himachal 98%.
65. ENERGY CONSERVATION
INDIA’S per capita consumption is very low and 35%
rural households are powerless but still india is
energy deficient . Thus , one alternative is to
preserve energy .
68. Smart grid
• A smart grid is an electrical grid that uses
information and communications technology
to gather and act on information, such as
information about the behaviors of suppliers
and consumers, in an automated fashion to
improve the efficiency, reliability, economics,
and sustainability of the production and
distribution of electricity.
69.
70. One –watt initiative
• The One Watt Initiative (or the proper One-
Watt Initiative) is an energy-saving initiative
by the International Energy Agency (IEA) to
reduce standby power-use by any appliance to
not more than one watt in 2010, and 0.5 watts
in 2013, which has given rise to regulations in
many countries and regions.
• It will reduce 1% of total co2 release.
72. PILFERAGE
• Kundi, ( )( ) as known in some parts of India,
is the criminal but widespread practice by common
people of stealing electric power. It is a crime and
punishable by heavy fines and, in some cases,
imprisonment.
• The simplest process is to put a direct wire-connection
to a main power route passing by a house or shop so
that electricity can flow to the consumer without
crossing the electric meter that is fixed by the State
Electricity Board to calibrate the load the sub-total of
your appliances is drawing .
• Insulating neutral can prevent power theft.
73.
74. PASSIVE HOUSES
• They are actually energy efficient building by
preventing cooling or heat losses in house.
• There are only 15000 to 20000 houses
around world.
• It has been calculated that it reduces 20-155
energy bills.
75.
76. STAR – RATED APPLIANCES
• Energy Star (trademarked ENERGY STAR) is an
international standard for energy efficient consumer
products originated in the United States of America.
• Devices carrying the Energy Star service mark, such as
computer products and peripherals, kitchen
appliances, buildings and other products, generally use
20%–30% less energy than required by federal
standards.
• Energy Star qualified fluorescent lighting uses 75% less
energy and lasts up to ten times longer than normal
incandescent lights.
• Reduces cooling costs — LEDs produce very little heat.
77.
78. ADVANTAGES
• Brightness is equal to or greater than existing lighting
technologies (incandescent or fluorescent) and light is well
distributed over the area lighted by the fixture.
• Light output remains constant over time, only decreasing
towards the end of the rated lifetime (at least 35,000 hours
or 12 years based on use of 8 hours per day).
• Excellent color quality. The shade of white light appears
clear and consistent over time.
• Efficiency is as good as or better than fluorescent lighting.
• Light comes on instantly when turned on.
• No flicker when dimmed.
• No off-state power draw. The fixture does not use power
when it is turned off, with the exception of external
controls, whose power should not exceed 0.5 watts in the
off state.
79. PRE-PAID ENERGY METERS
• With this, paying bills will no longer be a problem
and one can just pay the bill with the click of the
mouse.
• People had got worried due to increase in power
bills, pre-paid power meter has come to their
rescue.
• The meter comes with a unit called CIU or
consumer interface unit. It keeps the consumers
updated with the balance, hourly consumption
and units used at any time of the day.
• For people who have bad memory and forget to
recharge the prepaid meter, the CIU unit will raise
an alarm thrice when the balance drops to 100.
80.
81. IMPROVEMENT IN POWER QUALITY
• Power shortage/quality thus leads to large scale use of Voltage
Stabilizers, Inverters, Generators, UPS Systems, etc.
• Such Electrical Equipments, which require unwanted investments, in turn
not only lead to enhanced shortage in the overall situation but also
cause air and soil pollution by burning of coal, diesel, etc.
• Widespread use of lead-acid batteries in these equipments further
causes pollution of soil and water Voltage Stabilizers don’t have
efficiencies better than 80%. While a 1.5 Tr AC consumes 2 units; its
stabilizer consumes 0.4 units; it even consumes power if left ON when
AC is OFF.
• Assuming we have 10 Million ACs in India; on account of stabilizers for
ACs alone we lose around 4 million units, even during peak hours, which
is double the power generated by many large generating stations.
• Assuming an AC runs for 5 hours in a day, this means a loss of 20 million
units per day.
82. • The average efficiency of the domestic inverters is
50% and unlike fuel-based generators, inverters don’t
generate power.
•
• There is an estimated 50 million inverters being used
for domestic purposes each consuming say 250W/day
or 0.25 units. The power drain by inverters is thus to
the tune of 12.5 million units.
• Further, inverters use lead-acid batteries which
severely pollute the environment.
• UPS systems being like inverters cause power
wastage and pollution by use of lead-acid batteries.
83. • Diesel/Kerosene gensets not only cause pollution but also deplete
scarce natural resources. Pumps/Motors consume roughly 20% of
total electricity in India. An estimated 75% of this is consumed by
the pumps for agricultural sector mainly for water/irrigation. The
balance is for other motor applications.
• Most Indian pumps operate at 33% efficiency while motors have
an average efficiency of 40%. These cause heavy loss of electrical
energy.
• Taking usage of 4 units at 4 hours/day, the consumption in this
category is over 250 million units/day and the estimated loss is
160 million units /day.
• Pilferage (Power theft) in India is responsible for the
disappearance of 29% of electricity generated.
• In energy terms this amounts to 613.87 million units/day
84.
85.
86. CONCLUSION
• INDIA HAS A VAST POTENTIAL TO BE THE
ENERGY SURPULUS STATE DUE TO ITS
ABUNDANT RESOURCES AND EASY
AVAILABILITY, BUT IT NEEDS TO CUT ITS POWER
LOSSES AND CONTROL OVER POPULATION
WHICH LEDS TO OVERBURDEN ON ITS
PRODUCTION.
• India has the reputation of having the highest
distribution losses in the world with a figure of
nearly 47%, ranking above Burma with 36 %
losses and Bangladesh at 33 %.
• How do we bring these losses down and become
an energy surplus Nation?
87. THE SOLUTION IS :
• TO IMPLEMENT STRICT ANTI-PILFERAGE ACTS
• TO USE SMART GRIDS
• PROPER LOAD DISTRIBUTION
• GOOD POWER FACTOR{QUALITY}, SO AS NOT TO USE TRANSFORMERS
EXCESSIVELY
• AVOID LARGELY SUBSIDISED POWER DISTRIBUTION FOR POLITICAL
GIMMICKS
• IMPROVE POWER IMPLEMENTATION POLICIES ( TO PREVENT LIKES OF
DISASTAROUS INDUS WATER TREATY IN FUTURE)
• ENCOURAGING NON-CONVENTIONAL POWER BOTH FOR PUBLIC AND
GOVT. USE
• STRICT USE OF POWER RATED DEVICES
• GREEN CARBON RATED BUILDINGS AND LARGE SCALE USE TO BE
ENCOURAGED
• USE OF PREPAID POWER METERS AND OTHER ENERGY SAVING DEVICES
