1. CO-GENERATION - AN INDIAN MODEL VINAY KUMAR MANAGING DIRECTOR National Federation of Co-operative Sugar Factories Ltd. New Delhi (INDIA)

2. OUTLINE OF PRESENTATION • Co-generation • Indian Energy Scenario • Renewable Energy Development • Power Generation from Renewal source of Fuel • Power generation from Bagasse in sugar industry

3. CO-GENERATION • Co-generation in simple terms is defined as a process of using single fuel to produce two forms of energy i.e. • Thermal energy - for process • Electrical energy- for utilities

4. NEED FOR CO-GENERATION Power is the basic need for any activity. The growth of economy calls for commensurate growth in the infrastructure facilities. India is facing a very significant power deficit today to- the tune of 20,000 MW (18% of peak deficit). Besides the above, it is estimated that requirement of fossil fuel shall be as under :- • 450 million tonnes of coal • 94 million tonnes of oil Most of this energy consists of non-renewable sources and thereby in effect unsustainable.

5. BENEFITS OF CO-GENERATION • For the End-users/Co-generators: • Additional income from selling surplus electricity • Additional income from selling CHG • a) Certified Emission Reduction (CER) • b) Increasing security for clean energy supply

6. For the Power utility & National Economy • Saving primary energy consumption • • Reducing transmission and distribution losses • • Less burden on Government for power generation investment • • Less environmental pollution

7. INDIAN ENERGY SCENARIO • Total population - 1.18 billion • Rural population - 0.7 billion • Total number of villages - 640,000 • Number of un-electrified villages- 125,000

8. INSTALLED POWER SCENARIO • TOTAL INSTALLED CAPACITY : 1,48,265 MW • GROSS GENERATION : 640 billion units • PER CAPITA CONSUMPTION : 620 kWh/ annum • ENERGY SHORTAGE : about 8% • PEAK SHORTAGE : about 18 %

9. POWER GROWTH PERSPECTIVE * Electricity demand growing @ 8% annually * Capacity addition of about 92,000 MW required in the next 10 years * Challenge to meet the energy needs in a sustainable manner

10. THE CHALLENGE & VISION * India is facing formidable challenges in meetings its energy needs and providing adequate energy of desired quality in a sustainable manner and at a reasonable costs. * To meet the above challenge, Government of India took the decision to develop 10% power from renewable source by 2012. * The Government vision is to provide power to all citizens.

11. RENEWABLE ENERGY IN INDIA - POTENTIAL Wind Power - 48000 MW Small Hydro - 15000 MW Biomass Power - 16000 MW Bagasse Cogen - 5000 MW Solar Energy - 20 MW/Sq Km Waste to Energy - 2500 MW

12. BIOMASS TYPES OF BIOMASS WHICH CAN BE USED • Agricultural Field Residues • Agro Industrial Residues • Bagasse • Wood from plantation • Waste wood from industrial operations

13. CONVERSION TECHNOLOGIES • Biomass Technologies Currently Deployed • • Combustion • • Gasification • Cogeneration • • Bagasse cogeneration in sugar mills • • Non-bagasse cogeneration in other industries

18. PROMOTIONAL INCENTIVES FOR BIOMASS PROJECTS * Accelerated depreciation 80% in first year (boiler and turbine) * Income Tax holiday under section 80 1A for 10 years. * Concessional import duty, excise duty exemptions on equipments & components required for initial setting up of the project. * Sales tax exemption in some states. * IREDA provide loan for biomass power / co- generation projects.

19. * Preferential tariff in 14 states. * Ministry of Food provide concessional loan for Co-generation project @ 4% to the 40% of the project cost. * Ministry of New and Renewable Energy also grant capital subsidy @ 60 lacs per MW upto the maximum of 8 crores per project.

20. INDIAN MODEL OF CO-GENERATION.

21. A-CASE STUDY - EXISTING 5000 TCD SUGAR PLANT • EQUIPMENTS:- • Replacing / scrapping of the existing low pressure power plant which includes boilers, turbines and accessories after installation of efficient co-generation plant with high pressure 87 kg/cm2boiler, turbine, switch yard, transmission line and other accessories. • Replacing the existing inefficient turbine drive for Mill replace with energy efficient VFD – A.C. motors.

22. * Replacing of the existing inefficient turbines drives for fibrizer / shredder with H.T. motors after installation of Co-generation plant.

23. INVESTMENT:-

24. RETURN ON INVESTMENT:- Thus, the return on investment is less than 3 years.

28. PERFORMANCE DATA Performance of the Haidergarh Chini Mills (a unit of Balrampur Chini Mills Ltd.) a 5000 TCD plant for 3 years is given below for reference purpose only.

29. CONCLUSION • This is the appropriate time to plan for adoption of such technologies which can bring extra revenue to sugar mills. • Return on investment is normally 3-5 years depending upon selection of technology and sizing of equipment. • Selection of proper, size and addition of appropriate technology play a major role for maintaining higher plant load factor and higher efficiencies of the plant. • NFCSF provided consultancy services for around 20 sugar co-generation project from inception to commissioning.
