4/23/20151 CO-GENERATION - AN INDIAN MODEL VINAY KUMAR MANAGING DIRECTOR
4/23/20152 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
4/23/20153 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
4/23/20154 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.
4/23/20155 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
4/23/20156 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
4/23/20157 INDIAN ENERGY SCENARIO Total population billion Rural population -0.7 billion Total number of villages -640,000 Number of un-electrified villages-125,000
4/23/20158 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 %
4/23/20159 POWER GROWTH PERSPECTIVE * Electricity demand 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
4/23/ 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 *The Government vision is to provide power to all citizens.

4/23/ *Preferential tariff in 14 states. *Ministry of Food provide concessional loan for Co-generation 4% to the 40% of the project cost. *Ministry of New and Renewable Energy also grant capital 60 lacs per MW upto the maximum of 8 crores per project.
4/23/ INDIAN MODEL OF CO-GENERATION.
4/23/ 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/cm 2 boiler, turbine, switch yard, transmission line and other accessories. Replacing the existing inefficient turbine drive for Mill replace with energy efficient VFD – A.C. motors.

4/23/ 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.
