Impact of Load Shedding and use of UPS and Generators on Living Standards of Lahore Chapter 1:
INTRODUCTION
Energy is now days in Pakistan become the debate for traders, businessmen, house wives, students, ministers and all the victims from lack of energy. Lahore city experienced 12 hours extreme load shedding in this peak hot weather. The routine life of the residents is badly disturbed by the long load-shedding in the country. In recent years, the continuous and rapid growth in population in urban areas and growth of industrialization in Pakistan has affected the demand of electricity very badly in country. The demand of the electricity in country is much greater than the supply and production of electricity in country. This situation causes electricity crisis in Pakistan. The duration of load shedding reached14 to 18 hours a day. Shortage of electricity has reached 5500 MW, 12 to 14 hours in urban areas and 18 hours in rural areas as a result of landing time. Are the most affected industries is difficult to meet deadlines and deliver goods in time because of the energy problem. Many industries have been in the country closed, which caused the increase in unemployment and human suffering. The main reason overdue the load shedding is due to a clash between the Pakistan Electric Power Company (PEPCO) and the Pakistan State Oil (PSO) over late payment of dues that causes sudden decrease in thermal power generation. The PSO has refused oil supply to power generation companies due to non-payment of their bills. 40% of power houses are closed due to non-supply of oil. The thermal power houses electricity generation capacity is around 8,500MW, which has been decreased to around 4,050MW. Likewise, the "capacity was 3500 MW to 1223 MW is reduced, and the 221-capacity rental power generation" will be reduced to only 20MW. However, the amount of fuel is delivered, 4,000-5,000 MW of electricity can be added to the national grid. Electricity is the major font of power for any country greatest of the economic activities. Lahore is facing terrible load shedding as compared to other cities. It disturbed the lives of every resident of Lahore no matter in which field they are. Overview of Load Shedding

Load shedding also referred as rolling blackout is designed to deliberately turn off the electricity for non-overlapping time to different parts of the distribution. Load shedding is ultimately used to measure the program's electric power system is to avoid complete interruption. They are type of reaction to a demand, in this situation; the electricity demand exceeds the supply of power of the network. Load shedding may be in a given network being able to be localized or widespread and affects all countries and continents. Load shedding usually results from two reasons: Production capacity or inadequate transmission infrastructure to provide sufficient power to the lack of space. Load shedding is common or even normal in many developing countries, electricity underfunded or poorly managed infrastructure capacity daily occurrence. Load shedding is rare in developed countries because the demand accurately predicted, suitable infrastructure investment is planned and well-managed network, the following events will be taken into account in the planning of failure is unacceptable and can cause significant political damage to responsible government. Well-managed high-capacity systems to the current plan and announced in advance to public so they can work around, but in most cases occur without warning, usually the transmission frequency falls below the "safe" limit. When more companies to supply the demand for electricity production or transport, or installed capacity has more than you can deliver, companies, electricity available to his clients to resort to controlling. This act is called load shedding. Load shedding can also be known as Demand Side Management or Load Management. Load shedding frequently takes place when the total electric...
