Gloomy Power Scene By Arjumand Ansar

  1. 1. GLOOMY POWER SCENE--POSSIBLE REMEDIES Author: Engr.Arjumand Ansar Assistant Professor Electrical Department NEDUET email: Cell No: 0345-2265170
  2. 2. TOPICS TO BE DISCUSSED <ul><li>Need for power? </li></ul><ul><li>Present scenerio </li></ul><ul><li>Power utilization of Pakistan </li></ul><ul><li>Challenges in the energy sector </li></ul><ul><li>Action plan proposed </li></ul><ul><li>Conclusion </li></ul>
  3. 3. NEED FOR ENERGY: <ul><li>Energy is indisputably one of the prime catalysts for the development of a nation. It fulfills the promise of economic advancement and its availability ensures adequate growth. Conversely energy shortages lead to excruciating load shedding exercise resulting in economic stagnation. </li></ul><ul><li>Thus its need cannot be ignored. </li></ul>
  4. 4. PRESENT ENERGY SCENERIO: <ul><li>The present energy situation,led by fossil fuels namely as: oil, gas and coal are the most important sources of energy supply. </li></ul><ul><li>Pakistan’s indegeneous supplies of these </li></ul><ul><li>Fuels has three major concerns that are </li></ul><ul><li>*Depletion of resources </li></ul><ul><li>*enviromental impacts </li></ul><ul><li>*security of energy supply </li></ul>
  6. 6. CHALLENGES IN THE ENERGY SECTOR: <ul><li>Recent increase in energy prices could reduce economic growth. </li></ul><ul><li>The number of consumers has increased due to urbanization ,extension of electrical grid supply to unelectrified areas and villages. </li></ul><ul><li>Present population of more then 160 million(8 th most populated country) likely to increase to 210 million by 2025. </li></ul>
  7. 7. A survey claimed that house hold sector has been the largest consumer of electricity amounting for 44.2% of the total energy consumption followed by industries 31.1% agriculture 14.3% other government sector 7.4% commercial 5.5% and street lights 0.7% [5].
  8. 8. HISTORICAL TRENDS: <ul><li>Hence historical trends as well as predictions say that energy consumption will continue to incrrease ahead. </li></ul>
  9. 9. Projected oil and gas reserves in pakistan <ul><li>Conventional energy sources(coal,gas and oil) are limited ,oil and gas reserves are left only for 12 and 20 years respectively. </li></ul>
  10. 10. <ul><li>With the increase in use of electrical energy, enviromental pollution and global warming also constitute to the crisis. </li></ul><ul><li>Therfore the need of the day is to develop a comprehensive energy plan under the government umbrella thus to minimize the power crisis and to avoid higher power tariffs and pitfalls of the past. </li></ul>
  11. 11. ACTION PLAN PROPOSED: <ul><li>The strategy should have the following features </li></ul><ul><li>Power usage regulations </li></ul><ul><li>Increase energy efficiency </li></ul><ul><li>Substitute energy forms and discover new sources of enegy </li></ul>
  12. 12. *A fundamental policy should be framed based on the principles of commitment ,sustainability, efficiency and opportunity. *to achieve this the government and the public have to join and work to achieve this national goal. *Public should be made aware of the importance of energy conservation, through electronic and print media. *Ornamental lightning should be curtailed similarly illulminated hoardings should use energy efficient lamps and be switched on for a short period of time .
  13. 13. <ul><li>It is approximated that 7.5 million units/equipment of home appliances were used in the fiscal year 2005-06 consuming 2550 MW/annum that rose to 10 million units in 2007 consuming 3750MW thus increasing utility demand by 1000MW. </li></ul><ul><li>Thus from the above discussion , regulations should be made and endorsed and users should follow these regulations. Market surveillance should be done time to time. </li></ul><ul><li>Energy efficient equipment should be made available at economical prices. Substandard equipment made of low grade material should be banned of use. </li></ul>
  14. 14. <ul><li>Generation ,transmission and distribution facilities be enhanced . </li></ul><ul><li>Quick measures should be adopted to speed up the completion of under construction (hydal)generation projects ,such as; </li></ul><ul><li>Mangla-New Bong Escape 79MW(2010) </li></ul><ul><li>Rajdhani 132MW (2011) </li></ul><ul><li>Gulpur 120MW(2012) </li></ul><ul><li>But hydal power has its handicaps of water availability, which is constantly decreasing. </li></ul><ul><li>These have Long gestational periods and seasonal variations in river flow </li></ul>
  15. 15. <ul><li>Nuclear power generation should be promoted as it presently contributes only 2% of the total energy. </li></ul><ul><li>Conventional thermal power plants such as Guddu and Kot Addu,Hubco are playing their roles but as these plants are run by fuel oil they become a very costly option in the long run. Also the capital cost of these plants is high. </li></ul><ul><li>These plants release poisonous emissions participating in environmental pollution . </li></ul>
  16. 16. Thus with such exhaustible resources that are diminishing exponentialy,other of options power generation be also sighted out. <ul><li>Renewable energy can be the answer to our problems. </li></ul><ul><li>Renewable energy refers to sources of energy that occur repeatedly in nature and which can be harnessed by man. </li></ul><ul><li>Renewable energy can enhance diversity in energy supply markets ,secure long term sustainable energy supply and reduce global atmospheric emissions </li></ul>
  17. 17. RENEWABLE ENERGY RESOURCES: <ul><li>Such as </li></ul><ul><li>Hydropower </li></ul><ul><li>Biofuels </li></ul><ul><li>Solar </li></ul><ul><li>Tidal/wave </li></ul><ul><li>Wind </li></ul>
  18. 18. <ul><li>Hydro power was the main technology in e the 1970s but due to environmental and political pressures the development of this option is likely to decrease and be restricted to smaller schemes. </li></ul>
  19. 19. <ul><li>Solar energy can become a reasonable option as it can be extracted by photovoltaic cells (solar panels) and can produce electricity which can be directly fed to the consumer or an electric power grid or a storage device </li></ul><ul><li>The capital cost may be high but the life cycle cost is reasonable. </li></ul><ul><li>Photovoltaic cells and its system require very little maintenance as they have no moving part. </li></ul>
  20. 20. <ul><li>Pakistan is ideally located on the Sun Belt to take advantage of solar energy technologies. </li></ul><ul><li>Sind and Blauchistan are considered ideal for utilization of solar energy. About 85% of the villages in these areas are yet to be electrified, local power generation can be an optimal answer to their problems. </li></ul>
  21. 21. <ul><li>Wind energy is one of the fastest growing energy source in the world. It grew at an astonishing rate of 43% in the last one year alone. </li></ul><ul><li>Windmills can be feasible for remote villages ,deserts , mountainous regions cutting down the price of transmission and distribution. </li></ul><ul><li>The only wind data available is with the meteorological directorate. This data was recorded at a low height of about 4m and is not enough to have a true picture regarding the availability of wind energy. </li></ul><ul><li>Solar energy is a much economical choice for Pakistan as compared to wind energy-respective costs for solar and wind energy are (US cents/kWh) 20 and 77. </li></ul>
  22. 22. <ul><li>Tidal energy has been limited due to cost, technical and environmental reasons. </li></ul><ul><li>Biofuels can be an alternative to oil. Ethanol and biodiesel are the two main biofuels widely used today. </li></ul><ul><li>Still much uncertainty is there about the use of this technology in pakistan. </li></ul>
  23. 23. CONCLUSION: <ul><li>power crisis has to be dealt in a longsighted manner to produce fruitful results. </li></ul><ul><li>A balanced energy mix and accelerated maximum indigenous resource utilization. Should be targeted. </li></ul><ul><li>Promotion of Renewable resources with emphasis on the development of the rural and remote areas be considered. </li></ul><ul><li>An integrated planning and conducive environment are pre-requisites for developing self reliance in the energy sector. </li></ul>
