2. Share of Electricity Consumption

3. Cumulative Consumption of Large & Medium (Industrial & Commercial Sectors) • Projected saving is 375 GWh / annum considering 10% of energy consumption reduction (Equivalent to 3% of the overall national electricity consumption) Institutions – 1400 (20%) Consumption – 3737 GWh (80%) Institutions – 5523 (80%) Consumption – 927 GWh (80%)

12. Daily Electricity Demand - 2012

13. Sustainable Use of Energy Collaborative effort of Renewable Energy & Energy Efficiency

14. Sustainable Use of Energy Possibilities are there to reduce electricity consumption by 60% in conventional buildings

15. Energy Savings Potential and Technologies

16. IMPACT OF NATIONAL ENERGY MANAGEMENT PROGRAMMES • Estimated budgetary requirement for 5 years is around LKR 1.2 billion. • Anticipated financial saving: • - LKR 13 billion in the 1st yr, will exceed LKR 34 billion at the 5th yr, • - Over a period of 5 years: Around LKR 135 billion.

17. Energy Savings AchievedProjects Implemented Under National Energy Efficiency Award Scheme

18. Good Practices • Switching from fossil fuel to biomass • Implementation of ISO 50001 • Changing from Conventional to Green building • 200 accredited energy managers are involving in implementation of EE activities in industrial sector • Introduction of high efficient chillers • Introduction of high efficient motors and VSDs. • Introduction of sky lights • Switching from T8 to T5 and high efficient LEDs • Penetration of CFLs in domestic sector is more than 76%

19. kWh Energy Manager / Energy Auditor Regulation ISO 50001 Certification • Energy Labelling Programme • Code of Practice for Energy Efficient Buildings Recognition at national level for the involvement in energy conservation activities in both state sector and private sector organizations

20. Energy Management Program for Industrial and Commercial Sector Large Consumers – More than 600,000 kWh per Annum Appointing Energy Manager

21. Energy Management Program for Industrial and Commercial Sector Small & Medium Institutions – Less than 600,000 kWh per annum

22. Energy Management Program for Domestic Sector

23. Biomass Consumption

24. Biomass Utilization 1990 Consumption by sectors 2011 Total consumption – 13,156,000 MT

25. Biomass Utilization for Thermal Applications in Industries in Western Province Total consumption – 2875 MT/Day

26. Co-generation Applications Flue Gas loss 10 – 12% Mechanical Loss 2-5% Elect 15 – 30 % G Steam Turbine Process Heat 60 - 75 % Fuel 100%

27. Co-generation Applications Combustion chamber 1100 0C Supper heated steam Electricity Saturated steam Heat 184 0C Condensate 100 0C 30 0C

28. Cogeneration Applications • Textile Plant • Electricity + Heat for drying • Tea Factory • Electricity + Heat (Hot air) for drying & withering • Tire Factory • Electricity + Heat (steam) for curing • Rubber Gloves Manufacturing • Electricity + Heat (steam or thermic fluid) for curing • Hotel, Hospitals • Electricity + Hot water or Heat for generation of chilled water through absorption chiller • Commercial Buildings • Electricity + Heat for generation of chilled water through absorption chiller
