9 Options for Energy Savings Improvement of Efficiency of usage – Potential national savings Rs 400 Million per year Improvement of Efficiency of usage – Potential national savings Rs 400 Million per year Fuel switching – 50% saving in fuel wood or > Rs 10/kg MT by oil to wood changeover Fuel switching – 50% saving in fuel wood or > Rs 10/kg MT by oil to wood changeover

10 Efficiency Improvements Withering fans the prime candidate – 40% saving in electricity by VSDs Withering fans the prime candidate – 40% saving in electricity by VSDs Dryers – improved combustion Dryers – improved combustion –Better heat exchangers - current % to 65% - –Switching to SRC wood from logs – 50% reduction in wood consumption

11 Concerns & Barriers High cost of funds and lack of credit High cost of funds and lack of credit Perception that the tea quality will suffer Perception that the tea quality will suffer Inadequate appreciation of the potential Inadequate appreciation of the potential Lack of dissemination of considerable available information Lack of dissemination of considerable available information

12 Quality !!! & Consistency of Quality !!! is possible only through measurement and control

13 Alternate Energy Sources Grow you own fuel and fertilizer Grow you own fuel and fertilizer Use fuel at optimum size and moisture content for better combustion efficiency Use fuel at optimum size and moisture content for better combustion efficiency Use combined heat and power option and maximize waste heat usage Use combined heat and power option and maximize waste heat usage

14 CHP Options

16 Energy for Additional Revenue ! Using Steam Turbine Technology Using Steam Turbine Technology Minimum capacity 500 kW Water Cooled or Air Cooled options Minimum capacity 500 kW Water Cooled or Air Cooled options Grid Connection needed for export of power Grid Connection needed for export of power Using own fuel wood plantations Using own fuel wood plantations Foliage and added benefit Foliage and added benefit Carbon Credits Carbon Credits
