    more than 500 KW
  • Energy Auditing as per BEE Guidelines
  • Lighting installations upgraded to meet Energy
    Conservation Building Code
  • High Cost Measures are selectively implemented in
    category I, V VI buildings.

31
BARRIERS IN IMPLEMENTATION OF ENERGY CONSERVATION
STRATEGIES
  • Awareness Level very low
  • Energy Efficient fittings perceived to be
    expensive as the initial cost is high
  • Lack of proper guarantee (burning hours)
  • Wide Range of choices of lamps, though helps in
    innovative designs, causes barriers in
    standardisation
  • Energy Labeling (Star Rating) will go a long way
    in changing the perception and creating awareness
    on Energy Efficient Lighting.

32
CONCLUSION
  • Quality Life of Energy Efficient Lamps (T5) and
    Electronic Chokes are not as per parameters
    claimed by manufacturers
  • Energy Labeling (Star Rating) of BEE will go a
    long way in improving the quality and life of
    these energy efficient lamps and chokes
  • Continuous monitoring, Energy Surveys and
    Re-auditing is necessary to retain the cost
    effectiveness of these Energy Conservation
    Strategies

33
CONCLUSION - Contd
  • BSNL as on 31.11.07 has
  • 37936 Buildings and more than 45,000 Base
    Transceiver Stations (BTS)
  • 67,776,096 Telephone Connections (25.6 market
    share)
  • 35,491,814 Basic (82.17 market share)
  • 32,284,282 Mobile Telephones (14.57 market
    share)

34
CONCLUSION - Contd
  • Annual Electricity Bill of BSNL is more than
    Rs.14,000 Millions
  • Thus there exists a tremendous scope of reduction
    in Energy Bills
  • Energy Conservation has become a new Mantra
    (Focus Area) in BSNL to save Energy and to make
    this world a Beautiful and Greener Place to Live.
