Pakistan has faced an ongoing energy crisis for years due to rising demand outpacing supply. The gap between demand and supply reached 4,500MW in 2008, indicating a 40% deficit. While some short-term measures were taken, long-term solutions were not pursued aggressively. Pakistan has significant untapped hydropower and renewable energy potential but projects like Kalabagh Dam and Neelum-Jehlum were delayed, increasing costs. Alternative energy sources like solar and wind could power much of the country if developed properly. However, circular debt issues, line losses, lack of infrastructure investments, and insufficient focus on large-scale projects have impeded progress in resolving the crisis.
Energy crises in pakistan
- 1. BACKGROUND: Pakistan has been facing an unprecedented energy crisis since the last fewyears. The problem becomes more severe during summers. Initially, duringthe peak crisis there was a power outage of 3-4 hours daily but it keep onincreasing as the demand of electricity rises. According to the reports ofWapda, the electricity need of Pakistan increases more rapidly than it canbe generated which cause a major increase in the duration of loadsheading. The exact rate of demand and supply is given in the figurebelow: Fig 1: Rate of demand and supply of electricity (MW) from 2009 to 2030 The rate of supply diminishes due to the lack of Government interest in establishing new resources for the power generation. The last effort regarding this was made during the second government of Benazir Bhutto when some independent power plants were set up. Had they not been setup then we would have had a much bigger crisis with life almostcoming to a standstill. General Musharraf (R) after becoming Chief Executive used to talk about building dams especially Kalabagh Dam. This was one of the many promises he failed to keep. Even after that very few power plants have been set up to meet the demand for electricity and in a sense no actual effort for the electricity generation has been made since 1970s, that is when Tarbela and Mangla dams were put into operation and other dams, including Kalabagh, were actively pursued. When things start getting out of control, haphazard and quick-fix measures were sought. A typical example is the Independent Power Producers (IPPs) saga of the 1990s. In an attempt to avert an approaching energy crisis, as a result of negligible capacity addition during the 1980s and the early 1990s, the regime in 1993-94 decided to go for thermal generation through the IPPs. Undoubtedly, the IPPs provided a very healthy contribution at the supply end, enhancing power generation capacity by more than 5000MW but the effort did not meet the actual requirement of the cheap electricity for the country.
- 2. The last few years provide a perfect example of failure to make a timely response to the growing energy needs. A threefold increase in energy demand over the last two decades has been responded to with an illproportioned increment at the supply end. Consequently, with the advent of 2008 the gap between demand and supply grew to 4,500MW indicating a 40% deficit of electricity. The prevalent energy crisis has not appeared overnight — the omens were evident for a number of years but the authorities failed to react in time. Senior WAPDA officials claim that in 2002 the government was officially warned about the approaching electricity crisis and was asked to take immediate measures to enhance generation capacity. The timely warning failed to receive any appreciation. The attitude of the relevant authorities has thus indirectly contributed to the growth of the dire crisis. Some of the examples worth quoting here is that of Kalabagh Dam and the 969MW NeelamJehlum hydroelectric project. Kalabagh dam has been politicized to such an extent that its orchestration now appears to be next to impossible. Evidences suggest that the issue has been used to serve the vested interest of regimes and certain political and ethnical forces. It was to be completely functional in 1986 at a cost of 6 Billion but was neverconstructed and now if it is to be constructed it cost a price of 600 Billion. The other example is of 969MW Neelam-Jehlum hydroelectric project which was to be constructed in 2003 at a cost of $1.5 billion. It got abandoned until the present power crises intensified towards the end of 2007. The revised estimate is around $2.25 billion. The delay is costing thecountry a fortune – an extra $750 million in terms of project cost, apart from enormous monetary dents inflicted by the five-year delay. It is also noteworthy that WAPDA has traditionally pursued the major projects of national interest but failed to get the due positive response from the policyand decision- makers. Interestingly, WAPDA plays the role of a scapegoat, because the common man blames WAPDA for his sufferings. Electricity Generation Potential in Pakistan: Few years back Pakistan used to get half of its electricity from hydel power and remaining from thermal generation. However there is a limit to the extent of exploitation of hydel resources and

To meet the challenge there is a dire need to go to the alternate sources of energy. Fig: Different methods of Power Generation in Pakistan WE are fortunate to live in a country that offers us a multitude of natural resources yet to be harnessed for their entire potential. Arguably the most important of these, with reference to the present atrocious energy crisis and the intensifying effects of climate change, are the renewable sources of energy. The Pakistan Council for Renewable Energy (PCRET) has already undertaken some groundbreaking work in this regard by researching the potential of renewable sources of energy for commercial and personal use through localized design and development principles. Renewable energy can save our future generations from being unemployed. Our leaders need to use renewable energy to educate and employ youth, attract billions of dollars in FDIs and revive and sustain economy. Wind Energy: Pakistan can have wind energy on lines of China to generate 20,000 MW.China has planned to generate or 30GW with wind energy by year 2020. Gansu province alone is going to add 7Gw to its existing 10GW installed capacity by 2015. Wind energy project costs have dropped to below US $625 a kilowatt, making wind power generation a profitable business in Gansu. China is going to harness 750GW of offshore wind energy. In G-20 countries, 48 per cent investment in clean energy has gone in wind energy and it has added 40 GW of generating capacity, which is enough to power 30 million homes. Pakistan has been gifted with an immense wind resource. The wind map of Pakistan has been developed after extensive analysis carried out by National Renewable Energy Laboratory

Fig: Zorlu Wind Farm (6MW) at Jhampir (Sindh) Solar Energy: Solar sector is the fastest-growing clean-energy industry in the world. Prices of solar panels have declined by more than 60 per cent in the last 30 months. By the end of this year, solar modules are expected to cost half as much as they did four years ago. In 2010 alone, 17 GW of solargeneration capacity was added in the world which could power more than 12.5 million homes. China produced 48 per cent which is about 13GW, of the world’s solar panels in 2010, in coming two year time it will be the world’s largest market. The solar feed-in tariff, the price of solargenerated electricity, could drop below 12.5 cents for each kilowatt-hour (kWh) by 2015, equal to conventional coal-fired electricity by that time. Solar Energy is available at a rate of 1000 watts per square meter in Pakistan (about 19 Mega Joules per square meter of solar energy) according to the Alternative Energy Development Board (AEDB) sources. This can be converted to DC electricity with the help of Solar Photovoltaic cells, which may be used to pump water, operate fans, TV and telecommunicationsdirectly during daytime. The electrical energy generated during the day time (5-8 hours of sunshine), can also be stored in deep cycle lead acid batteries which can be used at night to provide power for lighting, radio, Television and fans. The system will be user-friendly and designed as astandalone system for each household, who will be trained to operate and maintain it. The user will

In addition, Solar Photovoltaic Panels can generate enough electricity to pump water from depth of 350ft, 700ft and up to 1000ft Fig: Solar Powered Tube well. Coal: Few years back Pakistan used to get half of its electricity from hydel power and remaining from thermal generation. However there is a limit to the extent of exploitation of hydel resources and thermal power plants due to environmental and other concerns. Modalities for overcoming the energy crisis are multifold. Fig: Coal Fields of Pakistan
- 6. To meet the challenge there is a dire need to go to the alternate sources of energy. Some people suggest that process of converting coal into product gas underground can be a good alternate source of energy. Technically this process is called as underground coal classification. Through this theunderground deposit of coal is treated with controlled fire. Gradually the coal turns into gas. Fig: Underground Coal Gasification process. The largest coal reserves of Pakistan exist in Thar which are about 175 Billion Tons or 850 Trillion Cubic feet. There this source can be cashed. A pilot project has been completed for the generation of 100MW electricity. Although the project has certain complications but they can be overcome by the allocation of needed funds according to the Thar Coal Underground Gasification Project sources.

This consists of all sizes of hydropower plants, including storagebased and high-head schemes on mountainous streams in the north and low-head, run-of-the river plants on rivers and canals in the southern plains.Pakistan has an installed hydroelectriccapacity of 5,928 MW of large (>250 MW), 437 MW of medium (>50 MW and <250 MW), and 253 MW of small to micro (<50 MW) plants, mostly in the northern parts of the country. This amounts to 6,608 MW of total capacity, or less than 15% of the identified potential. Fig: Existing Installed Power Generation Capacity in Pakistan Gilgit-Baltistan has maximum hydroelectricity resources as compared to anywhere in the country. The region has an area of 72000 square kilometers and a population of nearly two million. It is a mountainous region and the population is widely scattered. A large number of micro hydro power station units have been established in the area.

The major hydro-electricity sites are as under: Diamir Basha Dam Bunji Munda Akhori Kurram Tangi Other small and medium size projects: 4500 MW 7100 MW 740 MW ( 9 years for completion) 600 MW ( 5 years for completion) 83.4 MW (4 years for completion) 22,986 MW Total Potential: Total estimated investment: 31,000 MW 60 billion US$ Fig: Proposed view of Diamer Basha Dam project Kala Bagh Dam: Kala Bagh Dam is the most important project that must be completed to overcome the energy as well as water crises of Pakistan. It was to be completely functional in 1986 at a cost of 6 Billion but was never constructed and now if it is to be constructed it cost a price of 600 Billion.The project has its too much importance for the future of Pakistan but is under high political monopoly. Conclusion: After all the literature that we reviewed we can sketch up somerough hurdles that are there that won’t let implement our identified solutions. These hurdles are explained in short below;
- 9. Hurdles Implementing the Solutions to this Crisis: 1. Circular Debt: We identified that the Government is not serious in paying the IPP’s circular Debt. Once this debt is paid off, the IPP’s can pay off their petroleum import expenses and start producing at optimum levels. As long as the debt is left un-paid, we may continue to have such crisis forever. 2. Line Losses: We identified that WAPDA is facing huge line losses due to electricity theft or illegal usage of electricity. The burden is beard by the Government so in order to cover up such losses and to ensure adequate and clean facility of electricity; we must ensure that no body breaks into the transmission system. 3. Inadequate Power Generation Capacity: We identified that most of the systems here run on either Gas or Coal i-e they are thermal systems. Both Gas and Coal are considered as scarce and expensive commodities for electricity producers. 4. Lack of Capacity of Transmission of Electricity: We identified that most electricity transmission lines here in Pakistan are incapable of transmitting electric voltages of more than two phases. This makes them in-compatible to carry higher voltages, so even if we produce 3 phase electricity, it would be of no use in this case. We need to upgrade our transmission lines. 5. Lack of Capacity of Distribution of Electricity: We identified that we lack high quality lower end grids that are used to carry electricity from power houses to the ultimate consumers via grid stations. The infrastructure is old and deteriorated. 6. Privatization of K.E.S.C: After the privatization of K.E.S.C is enhanced its production capacity but the Government for a certain reasons did not provide it with adequate distribution network. 7. Government’s dependence on IPP’s: The IPP’s at current are responsible to provide electricity to half of our country. As the Govt. did not pay their debt so now they are charging or demanding higher per unit prices from the consumers. This hike in electricity prices is affecting not only our local industries and homes but is also affecting our exports of manufacturing goods. The govt. must intervene and pay out the circular debt. Or provide subsidy on electricity. 8. Lack of Government’s interest in building dams: Pakistan being rich in hydro-electricity resources can generate all of its electricity through water but this sector is totally neglected by the Government and no mega Dam project is initiated for the last 30 years. Hydroelectricity being the cheapest is the need of the country but was totally neglected. The govt. should take this seriously and allocate funds for the initiation of Mega Dam projects.
- 10. Recommendations: Following are some recommendations for resolving the energy crisis in the country: 1. Funds must be initiated on the priority basis to solve the biggest and most important problem of the energy crises.To overcome the problem on urgent basis, electricity from the neighboring countries can be utilized and during this duration means should be adopted to generate energy. 2. IPPs should be paid on regular basis so that no short fall from the Thermal power sector is encountered. 3. Improvement of the efficiency of various Thermal Power units. Thisis very important for utilizing the installed capacity of the National Grid. The investment required for the rehabilitation of the Thermal Power units in various parts of the country is very less as compared to the money spent on Rental Power Projects. 4. Mega projects like construction of Big Dams should be initiated on priority basis and for this purpose foreign investment should be taken. 5. The funds allocated for solving energy crisis should be used for rehabilitation of thermal power units, establishment of small and medium sized hydroelectric power plants. 6. Along with big dams, small dams and micro-hydro projects must also be started for the short term solution. 7. Government should take all the provinces onboard and solve confusions regarding Kalabagh dam keeping in view of its importance for the betterment of the country. 8. Alternative energy from unconventional means like Thermal, Solar, Tidal and wind must be encouraged. For this purpose private sector can be involved. 9. The government should also enhance partnership with trade partners like China to establish Photo Voltaic cell manufacturing units in Pakistan in order to promote solar energy. 10. The electricity for agricultural sector can be provided by covering the irrigation canals with solar panels. The initial funding required for this project can be derived from the agricultural subsidy. 11. Immediate funding must be done for the completion of Thar Coal project and the project must be extended to the large scale for the utilization of Thar coal for energy purposes. 12. The air corridor of Gawadar must be utilized completely only for the purpose of wind energy 13. In northern areas, Private sector must be encouraged for the installation of turbines on high energy streams to overcome the energy need locally. For this purpose community funding can also be done to meet the initial cost. 14. Industries that consume 32% of our electricity, must apply Energy Conservation Systems and Management measures. They can start producing their own energy with their own investment without depending upon the grid.
