  1. Sustainable Indigenous Energy for Tea Industry in Sri Lanka L P Jayasinghe Bio Energy Association of Sri Lanka

  2. Sri Lanka Energy Mix

  3. Electrical 0.75 kWh/kg of MT 15% [1] Potential Optimum 0.23 kWh/kg [4] Total Energy Consumption 7.1 kWh/kg of MT 100% Thermal 21700 kJ/kg of MT - 85% Potential Optimum ??? Energy Needs for Tea Production in Sri Lanka

  4. Options for Energy Savings • 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

  5. Efficiency Improvements • Withering fans the prime candidate – 40% saving in electricity by VSDs • Dryers – improved combustion • Better heat exchangers - current 20- 40% to 65% - • Switching to SRC wood from logs – 50% reduction in wood consumption

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

  7. Quality !!! • & • Consistency of Quality !!! • is possible only through measurement and control

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

  9. CHP Options

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

  11. Steam Turbine Generator 300 kW

  12. Carbon Credits Potential • CO2 Equivalent of 500 kw – 3000 Tons • Current CER Prices – $10-15 per Ton • Potential revenue per factory - $ 30,000/yr • The CERS from thermal energy not included • National potential > $ 15,000,000

  13. Barriers to Overcome • Funding for the capital expenditure • Generation of adequate energy plantations • Grid connection issues • Bundling to get full benefits of Carbon Credits • Lack of appreciation of true potential

  14. 500 kW Dendro Plant with Grid Connection Operating Parameters Carbon Revenue not included

  15. Lets Grow Our Own Energy Re-Greening Sri Lanka
