&
PRODUCTION OF ELECTRICITY IN KARNATAKA

4. Power System
Components
 Generation subsystem
 Transmission subsystem
 Distribution subsystem
 Protection & control subsystem
Most complex man made system !!

5. Basic Power System
Structure

6. STATUS OF ENERY SECTOR
IN KARNATAKA
 State has no deposits of coal or petroleum,
and therefore has to import it .
 The electricity source for Karnataka has a
mix of hydel, thermal and wind and
accounts for 56% of the commercial need.

7.  In Karnataka, non-commercial energy
sources like firewood, agricultural
residues, charcoal and cow dung
account for 53.2% which demonstrates
a high dependency on biomass to meet
rural energy needs.

8. Power Projects in Karnataka

11. TRANSMISSION OF
POWER
 The Karnataka Power Transmission
Corporation Limited, also known as KPTCL
is the sole electricity transmission and
distribution company in state of Karnataka.
 KPTCL buys power from power generating
companies like Karnataka Power
Corporation Limited (KPCL) and other IPPs
and sell them to their respective ESCOMS

12.  Bangalore Electricity Supply
Company.
 Mangalore Electricity Supply
Company ( Mescom ).
 Hubli Electricity Supply Company.
 Gulbarga Electricity Supply Company.
 Chamundeshwari Electricity Supply
Company.
ESCOMS UNDER KPTCL

14.  Primary source :- MESCOM (State Supply)
 Secondary source :- PRIVATE D.G SETS

15. Heart of the electrical system

16.  Basic function of power house is to
synchronize and provide a continuous
supply of electrical power.
 It takes power from state supply, steps it
down and then transmits it to the location of
load.
 In case of power failure it automatically
starts the D.G sets which compensates for
the failure of power.

17.  Location:- behind cafeteria
 Supplies to:- AB-1,AB-2,AB-3,AB-4
WORKSHOP, LIBRARY.
 State Supply :- 200A at 11KV
 Generator Capacity:- 4 units of 415V,
500KVA
POWER HOUSE

21. POWER HOUSE 5:-
 Location :- In front of 16th block
 Supplies to:- 14th,15th,16th,17th block
hostel, AC plant
 State Supply:-400 A at 11 KV
 Generator Capacity:-2 units 500 KVA,
415 V

22. POWER HOUSE 6:-
 Location :- AB 5
 Supplies to:-AB 5, AC plant
 State Supply:-200 A at 11KV
 Generator Capacity:-2 units of 625 KVA,
415 V

24.  Transmission losses account for 5% of
the units consumed.
 Power Houses are to maintain an
optimum value of power factor so as to
minimize the losses , failing to which
supply of power by state is stopped
automatically.
 Unit-KWh number of kilowatts
consumed in an hour.

27. Mescom Supply-stepped
down by transformer.

28. D.G set – from
outside

29. Inside a D.G set- the
diesel engine

30. Instrument panel

31. Instrument panel

32. Cooling Tank

33. Exhaust Pipe

34. TRANSMISSION

36.  Consumption of power is calculated into
three different categories :-
1.Hostel
2.College
3.Quarters
 Total units consumed is calculated as the
sum total of units taken from state supply,
total units generated from D.G sets and
units lost during transmission.

46. CONCLUSION

53. A Step Ahead…..
 The Manipal University (MU), has embarked on a joint project with the
Advisory Services in Environmental Management to develop the MU
campus into an Eco-City.
 ASEM is a joint programme of the German Technical Cooperation (GTZ)
and the Indian Ministry of Environment and Forests
 The identified goals are, alignment to ISO 14001 and trainings on energy
conservation, sustainable design and Eco-budgeting
 A training centre on Urban Sustainability Management would also be
established to provide courses on Urban and Environmental Management.
 The project takes a two-winged approach: on the one hand, promoting the
establishment of an ISO 14001 certified environmental management system on
campus will directly impact the academy’s resource use and environmental
performance, while on the other hand, catalysing the setup of a study scheme
on environmental management via international university partnerships serves
to multiply environmental management capacities beyond the campus itself.

54. Efforts made by MIT
 a) Up gradation of air-conditioning system
It includes replacement of old air-conditioning
units with power efficient water cooled screw
chillers, cooling tower upgrades, unitary air-
conditioner controls, implementation of
building automation system, with sensors
installed in entire building for efficient cooling,
automatic switching ON/OFF based on
occupancy and fixed time schedule, use of R -
138 gas system (environment friendly).

55.  b) Solar Water heaters
Since the coastal belt of Karnataka is
blessed with bright and sunny days
almost throughout the year excepting
the monsoon season, solar energy is in
abundance and can be captured to meet
our heating needs.

56. Awards and Recognition
 2008-2009 : - Certified as an ISO
14001:2004 Organisation
 2004-2005 : - Rajiv Gandhi Parisara
State Award
 2002-2004 : - District Award for
Environment- first prize
 1999-2000 : - District Award for
Environment- first prize

58. Let start a new beginning…..
with hope of a new and smarter
world….
THANK YOU.
