CO-GENERATION - AN INDIAN MODEL

VINAY KUMAR

MANAGING DIRECTOR

National Federation of

Co-operative Sugar Factories Ltd.

New Delhi (INDIA)


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


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


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.


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


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


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


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 %


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


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.


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


BIOMASS

TYPES OF BIOMASS WHICH CAN BE USED

• Agricultural Field Residues

• Agro Industrial Residues

• Bagasse

• Wood from plantation

• Waste wood from industrial operations


CONVERSION TECHNOLOGIES

  • Biomass Technologies Currently Deployed

    • • Combustion

    • • Gasification

  • Cogeneration

    • • Bagasse cogeneration in sugar mills

    • • Non-bagasse cogeneration in other industries

SUGAR INDUSTRY


State


STATE WISE STATUS OF CO-GENERATION


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.


*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.


INDIAN MODEL OF CO-GENERATION.


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.


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


INVESTMENT:-


RETURN ON INVESTMENT:-

Thus, the return on investment is less than 3 years.


B-CASE STUDYNEW 5000 TCD SUGAE PLANT

MAIN EQUIPMENTS AND THEIR COST:-


RETURN ON INVESTMENT (Power Export):-


EXECUTION OF TIME REQUIRED


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.


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.
