Introduction Demand for power is ever increasing Generation of power at cheaper tariffs to consumers is a challenging task Availability of cheaper sources of fuel & efficient generation are key to un-interrupted economic supply of power Green Revolution and clean technologies will become the order of the day Continued research and commercialization of cleaner generation needs emphasis to mitigate pollution Demand for power is ever increasing Generation of power at cheaper tariffs to consumers is a challenging task Availability of cheaper sources of fuel & efficient generation are key to un-interrupted economic supply of power Green Revolution and clean technologies will become the order of the day Continued research and commercialization of cleaner generation needs emphasis to mitigate pollution

Which Fuel ?????

Fuel Alternatives In-exhaustible Exhaustible Coal Natural Gas Oil Nuclear Fissile Materials Coal Natural Gas Oil Nuclear Fissile Materials Water (Hydel) Wind Sun (Solar) Water (Hydel) Wind Sun (Solar) FUELS Bio-ethanol, Fuel Cells, Hydrogen as fuels are still in the R&D stage for generating power for commercial purposes Fossil Fuels Eco-friendly, Abundantly available, but no control on availability Eco-friendly, Abundantly available, but no control on availability

Statistics of Generation Mix in India Generation skewed towards coal Statistics is always looked at with lot of skepticism: Once one hundred men went to the forest to cut the woods. They took two women with them for cooking food. Before the onset of the winter two men married the two women. The statistician wrote: 2% of the men married 100% of the women!

Emission Standards for Power Plants Particulate MatterSOxNOx 150 for 210MW capacity and above No specific limits but stack of 275m for 200 to 500MW for better dispersion of SOx Gas based plants need to meet certain standards: 50 for 400MW & above 75 for 100 to 400MW 100 for less than 100MW 350 for less than 210MW capacity (Values in mg/Nm3) These are recommended standards. Our aim should be to achieve lesser emission of these quantities. These are recommended standards. Our aim should be to achieve lesser emission of these quantities.

Environmental Issues with coal as fuel Burning coal without increasing global carbon dioxide levels is a major technological challenge Coal when burnt gives rise to a variety of wastes which must be accounted and controlled Mercury, NOx, SOx and Solid Particulate Matters in the form of ash are the main pollutants Solid and fly ash quantify as high as 50% of Indian Coal Global warming associated with emission of CO2, NOx is a major issue with world community Burning coal without increasing global carbon dioxide levels is a major technological challenge Coal when burnt gives rise to a variety of wastes which must be accounted and controlled Mercury, NOx, SOx and Solid Particulate Matters in the form of ash are the main pollutants Solid and fly ash quantify as high as 50% of Indian Coal Global warming associated with emission of CO2, NOx is a major issue with world community Coal SOx NOx SPM Ash By Products

Stop and then Think??

Natural Gas Production & Utilization

Natural Gas as vital fuel Natural Gas Proven methods of power generation at high efficiencies Mixture of hydrocarbons, mainly methane, Produced either from gas wells or in conjunction with crude oil production. Proven production techniques can ensure continuous supply Power Generation with no ash, least particulate emission, lesser hazard to environment

Natural Gas Reserves India's natural gas reserves are currently estimated at about trillion cubic feet (tcf), or about 0.5% of the world total. This will go up as and when we strike oil/gas in the unexplored river basins

Why should Gas based power projects be encouraged? ………..1 Coal based thermal power projects are suitable for base load continuous operation due to their inherent drawback of slow ramp up and slow cool down. In India, coal based thermal power projects are being used as peaking stations also, which is not a good practice of economic dispatch; thanks to the reduced quantity of generation using hydro and gas based power projects. Poor performance of India's generating units has been a principal cause of power storages and unreliable quality of power supply. The primary culprits are the coal- fired thermal power stations which accounts for over 50% of total installed capacity. The average plant load factor (PLF) of thermal power stations in India is less than 60%, even though they vary across regions. Most of these units are old and have already logged more than 100,000 running hours and their performance can only be improve through a long-term rehabilitation or modernization with life extension program.

Why should Gas based power projects be encouraged? Gas may last for another 60 years at the current rate of consumption Increased find of natural gas and oil in KG basin and other parts of India likely to ease out the rising oil and natural gas prices in the near term Un-explored river basins likely to boost the availability of gas by another 10 to 20 years Natural gas combined cycle generators can reach 60% efficiency for converting heat energy into electricity. Fixed cost of generation for gas based power is less. (30% less than coal based generation) Construction time required for natural gas based power projects is far lower compared to coal based power projects. Coal projects require more than 48 months where as gas based ones require less than 30 months Owing to the requirement of lesser space, lesser water and lower emissions, the natural gas based projects can be located very near to the load centers, which is not possible in case of coal based power plants. Natural gas also produces % lesser CO 2 emissions for the same amount of electricity generated by Coal. Nuisance of Ash disposal is totally absent in gas based power projects.

Natural Gas Usage

Market for Natural Gas To monetize the natural gas out of the wells of KG basin, the oil companies should have large, long term anchor consumption contracts Only Power and to some extent fertilizer, metallurgical plants can provide such anchor contracts Retail, transportation sector or city distribution cannot provide adequate market for such anchor consumptions Power projects in AP and other states require gas and utilities are suffering due to reduced availability of gas All the naphtha and diesel based power projects can be converted to fire natural gas to make the projects economically viable and to produce power The gas should be made available to power sector at rates affordable for consumption say at less than 4 to 5 $/MMBTU so that the gas based power projects can compete with imported coal fired power projects Price of the Natural gas should not be compared to that of Naphtha for pricing purposes. It would be like comparing Idlis of 5 star hotel with Udupi darshini Idlis.

Cost of Generation using Natural Gas Levelized fixed cost would be about Rs. 0.8 / kWH, cheaper than that of coal based generation

Summary Energy production and environmental protection are not mutually exclusive Global warming and greenhouse effects can be mitigated by using clean fuel as much as possible Natural Gas needs to be given the importance for generation of electricity; Gas is used to generate 24% electricity world over. (India uses only 7%) There is an overwhelming market for natural gas in power sector (approx 120MMSCMD); Availability is 66 MMSCMD – Assured market for the next 15 years at least. All other sectors put together will not come to half of requirement of power sector Research on better combustion techniques and metallurgy is increasing the efficiency of the natural gas fired power plants. Preferential pricing should be given to the natural gas used for power generation Energy production and environmental protection are not mutually exclusive Global warming and greenhouse effects can be mitigated by using clean fuel as much as possible Natural Gas needs to be given the importance for generation of electricity; Gas is used to generate 24% electricity world over.

Conferences are many times called the meeting of the bored!! Hopefully I did not contribute to this !!!!
