Basic Power System Structure

STATUS OF ENERY SECTORIN 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.

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.

Power Projects in Karnataka

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

Bangalore Electricity Supply Company.

Mangalore Electricity Supply Company ( Mescom ).

Hubli Electricity Supply Company. Gulbarga Electricity Supply Company. Chamundeshwari Electricity Supply

Company.

ESCOMS UNDER KPTCL

POWER SOURCE OF MIT

Primary source :- MESCOM (State Supply)

Secondary source :- PRIVATE D.G SETS

POWER HOUSES OF MIT

Heart of the electrical system

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.

Working of power house

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.

TRANSMISSION

CONSUMPTION

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.

EXPENDITURE

Hostel, college and quarters come under different categories of billing and hence they are billed at different rates , highest being the college.

Overall expenditure includes the electricity bill and cost of running D.G sets and the transmission losses & electricity tax on the electricity bill.

Cost per unit of electrical energy ranges from Rs 3 per unit to Rs 7 per unit.

D.G sets consume 70-85 liters of diesel per hour of running.

CONCLUSION

Environmental policy of Manipal University

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.

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). 

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.

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
