Sustainable Development of Power Resources in Pakistan


In order to have sustainable development of power resources the following measures must be taken;

Conservation of resources

•    Preservation and conservation of the non¬renewable resources of the earth to guard against the danger of their future exhaustion

Use of advanced technology

•    Development of renewable resources of energy by using advanced technology

Control over non-productive usage

•    Non-productive use and wastage of power resources must be checked strictly

Public awareness

•    A public awareness program should be introduced through the media

Government policies

•    Government and private institutions must ensure preservation of energy by the protection of the environment by enforcing the strict laws through environment protection agencies

Effective marketing

•    Marketing of power resources to be done a way which will avoid non-productive uses faulty and damaged transmission lines should be replaced on an emergency basis to avoid losses in electricity

Effective planning

•    An integrated and coordinated approach to development planning is required to ensure that power resources are conserved to meet the needs of the future generation and improve the environment for the benefit of the population.



Energy Resource and Sustainable Economic Growth


Profile of Electricity Generation:

Main organization responsible for Electricity Generation

•    The Water and Power Development Authority (WAPDA) and
•    Karachi Electricity Supply Corporation (KESC)

Responsibilities of main organizations

•    Power generation
•    Transmission and
•    Distribution of electricity
•    The Karachi Nuclear Power Plant, (KANUPP), a public sector organization
•    And some independent private producers (IPP) are also involved in power generation

Energy Resource & Sustainable Economic Growth


•    Adequate and assured supply of electricity is a pre¬requisite for sustained economic growth.
•    Despite having an enormous potential of energy resources, there is a shortage of energy supplies which is severely affecting the domestic, industrial and commercial sectors.

Reasons for shortage of energy in Pakistan:

Power plants not working at full capacity

•    Many of the power plants are not working to their full capacity due to financial constraints, lack of technical expertise and maintenance facilities.

Reduction in water flow in winters

•    During the winter season the hydel power generation decreases with the reduced flow of water in the rivers.

Losses of electricity

•    The national grid system supplies electricity to all the provinces. Long transmission lines cause losses of electricity.

Siltation

•    Siltation in the reservoirs of dams also causes disruption in electricity generation by reducing the flow of water.

Power Theft

•    Power theft occurs on a large scale.
•    Until recently the ghastly loss and theft from Karachi Electric Supply Corporation (KESC) was approxi¬mately 41%. That is, 41% of the electricity generated was not paid for by those using it.
•    Water and Power Development Authority (WAPDA) suffered about 21% losses in transmission and distribution.

High price of fuels

•    The high price of fossil fuels increases the cost of electricity generation.

Growing demand

•    Industrialization, urbanization and rural electrification have increased demand for electricity.

Private Sector Power:

•    Government is encouraging the private sector to invest resources in power generation
•    Out of 19 projects 5 have commenced commercial operation and are delivering power. Hub Power Project is generating 1292 MW


The Western Mountains of Pakistan


 

The Western Mountains

    Safed Koh Ranges up to 4712 meters
    Waziristan Hills up to 3513 meters
    Sulaiman Range up to 3383 meters
    Kirthar Hills up to 2174 meters


Safed Koh Ranges (Height up to 4712 meters)

Location:

•    The Safed Koh Ranges are located in an east west direction south of the Kabul River.

Topography:

•    They are called Safed Koh (White mountains) because their peaks are often covered with snow.
•    They also have limestone ridges

Drainage:

•    River Kurram flows to the south of this range and the Kurram pass provides a route into Afghanistan.

Valleys of Kohat and Peshawar

•    The Kohat Valley is located at the other end of the Kurram Pass.
•    It is dotted with springs and a number of limestone ridges.
•    With the help of irrigation, the valley is farmed.
•    Wheat, rice and sugar-cane are cultivated there.
•    Another valley in this region is the Vale of Peshawar, drained by the rivers Kabul and Swat.
•    It is a fertile, alluvial plain irrigated by canals originating from the Warsak Dam on the River Kabul.

Special Feature or Importance

•    They offer route to Afghanistan through Kurram pass

Waziristan Hills (Height up to 3513 meters)

Location:

•    The Waziristan Hills are located between the Kurram and the Gomal rivers.
•    Along with the Safed Koh Ranges, these hills form a rampart between Pakistan and Afghanistan.

Topography

•    They are devoid of vegetation

Drainage

•    The Kurram dam on the Kurram river is the main source of irrigation water.

Bannu Valley

•    The Bannu valley is located to the east of the Waziristan Hills
•    Bannu, near the Tochi Pass, and Dera Ismail Khan, near the Gomal Pass, are important towns and military centres.
•    The Bannu valley is a low-lying basin bordered by hills and mountains and drained by streams, with braided channels (see Fig.1.35b).
•    The valley has deposits of clay and boulders brought down by streams.

Special Feature

Economic Activities and Lifestyle in the Western Mountains:

Agriculture

•    The Western Mountains are mostly bare of vegetation.
•    The climate and relief do not support farming.

Drainage

•    Canal irrigation is not possible because of the mountainous terrain and rugged landscape.

Impact on people

•    Transportation facilities are limited.
•    Except for a few urban centres like Peshawar and Kohat, the rest of the area is not connected by air or rail networks.
•    Only a few areas are accessible through main (metalled) roads.
•    Most of the areas are accessible only by unmetalled roads.
•    Life in the Western Mountains is difficult because of the rugged landscape.
•    The cost of supplying infrastructure - water supply, transport facilities, electricity, and telephone lines is much higher than in the plains.
•    As a consequence developmental projects, e.g. mining activities, industries, educational facilities, have not been established.
•    These factors adversely affect the lives of the inhabitants.
•    They are deprived of even the basic necessities of life.
•    Nomadic lifestyle is common and sheep and goat rearing is the main occupation.
•    The population density is lower than 100 persons per sq. km.
•    There are abundant mineral resources in the Western Mountains but due to the difficulty of extracting them, they have not been explored or exploited.

People and Economy in Northern Mountains of Pakistan



Harsh living due to topography and climate conditions

•    The population, settlement, and economic activities within the Northern Mountains have been greatly influenced by the variations in topography, which impose harsh living conditions and tend to restrict movement and communications.

Low economic growth rate

•    The economy in the Northern Mountains has developed on traditional lines.
•    Much of the Northern Mountains area is characterized by a very low economic growth rate combined with a high rate of population growth, which prevents growth in the already low level of per capita income (average income per person).

Dependency on agriculture

•    Most of the population is dependent on agriculture, primarily subsistence agriculture and cattle breeding.
•    Farming is practiced on terraced fields where wheat, rice barley, maize and vegetables are grown.

Cottage and small scale industry

•    During winter many people work in cottage and small-scale industries.
•    The outputs of these industries are carpets, embroidered material, rugs and other handicraft items.
•    The domestic and foreign tourists, who visit these places, mainly during the summer season, value these products.
•    The major industries include the processing of food grains, making vegetable oil, and refining sugar.
•    Fruit processing is also an important industry.
•    There are a few modern industries but mineral resources have not been explored as yet.

Hydro-electric Potential

•    The Northern Mountains have major hydro-electric potential, but the development of hydro-electric resources requires huge capital investment, which is not available.
•    The skilled labor needed to organize and manage the development of natural resources is also limited due to the low literacy rates.

Poor facilities

•    Most of the people face a shortage of safe drinking water and poor health.
•    Moreover food production in the Northern Mountains has not kept up with the population growth so they also face malnutrition.

Trade links

•    Some of the towns in the Northern Areas like Mingaora, Murree, Kaghan and Gilgit have regional trade by road with cities like Rawalpindi, Islamabad, Peshawar and Abbottabad.
•    However, due to difficult terrain and limited transport facilities it is difficult to carry out regional trade on a large scale.
•    Tourism is also popular in the Northern Mountains but it has had an adverse impact on regions where tourist numbers exceed the facilities available.

National Grid System of Pakistan



•    Pakistan's power transmission system has power¬ generating stations and load centers which are linked with each other creating one of the world's largest National Grid systems.
•    The National Grid connects hydel generation in the north and thermal generation in mid country and the south managed by WAPDA (Water and Power Development Authority) and KESC (Karachi Electricity Supply Corporation).
•    It consists of a large network of transmission lines and grid stations to transmit power to load centers and then to commercial and domestic consumers throughout the country.

The purpose of formation of National Grid System:

Supplying electricity according to requirement

•    The purpose of formation of National Grid System is to supply electricity to different areas according to their requirements and not on the basis of their own power generation.

For example areas with more demand

•    For example some areas of Pakistan where heavy industries are located require more electricity than they are capable of generating.
•    Supplying electricity through the National Grid system solves this problem.

For example areas with more supply

•    On the other hand, there are some areas where physical and human factors can generate more electricity than their actual requirement.
•    This surplus electricity can then easily be transferred to other areas through this system.
•    However, there is lot of wastage of electricity through the transmission lines and grid stations if they are not properly maintained, also due to the long distances involved.

Installed Generation Capacity of the Water and Power Development Authority (WAPDA)



•    It has installed both hydro and thermal power stations but the potential of the hydro power has not been fully exploited.
•    The hydel potential located in the Northern Area and KP still remains largely untapped.
•    In 1997-98
o    Hydel generation was     42 % of the electricity generated
o    Thermal electricity was     58 %.of the electricity generated



Glaciers of Pakistan



•    Many of the world's glaciers lie in the mountains of Pakistan.
•    A glacier is a tongue shaped mass of ice moving slowly down a valley.
•    Some of the important Glaciers are;
o    Baltoro:     58 km long,         in the Karakoram Range.
o    Batura:         58 km long,         in the Hunza valley in the Karakoram Range.
o    Siachen:     78 km long,         located in the Karakoram Range.

The Mountain Valleys

•    In the mountainous north, a number of valleys attract many domestic and foreign visitors.
•    The larger, more popular ones are:
    Swat         (Hindu Kush)
    Chitral         (Hindu Kush)
    Dir         (Hindu Kush)
    Gilgit         (Karakoram)
    Hunza         (Karakoram)
    Baltistan     (Karakoram)

Importance of Northern Mountains

Source of irrigation

•    Snowcapped peaks melt during summer to drain water into River Indus and its tributaries which irrigate vast Indus plains

Natural border

•    Natural border to China and Central Asian states

Trade route

•    A land route through Karakoram Highway has been opened to carry out trade
•    Historical passes connect Pakistan to China and Afghanistan

Provides protection against extreme cold temperatures

•    Mountain peaks provide protection to Pakistan against the cold winds from Central Asia.
•    The temperature does not go below freezing point over the Upper Indus Plain and climate remains tolerable through the year

Source of valuable minerals and raw material to industries

•    A source of valuable minerals, timber and fruits
•    Provides raw material to several industries like furniture, paper, chipboard industry, chemical industry etc

Tourism Potential

•    Scenic beauty promotes tourist resorts which are source of income to local people during summer

Rural Electrification in Pakistan


•    67.5% of population lives in rural areas
•    Most of rural areas are deprived of even basic facilities of modern life
•    Electricity can prove milestone in rural development

Advantages of Rural Electrification in Pakistan:

Installation of tube wells

•    Tube wells can be installed for irrigation

Controlling Water logging and Salinity

•    This also helps to control water logging and salinity

Growth in Agriculture

•    There will be increase in agriculture production


Growth in small scale industries

•    Small scale industries can be developed to provide employment and to meet the demand of industrial goods

Improvement in living standards

•    Standard of living increases.
•    People can use electrical appliances

Access to information technology

•    People can receive the electronic media and access information technology

Programs for Rural Development in Pakistan:

•    There are many programs for rural development like
o    Village Aid
o    Basic Democracy and
o    Rural Works Program
•    Providing electricity to rural areas was one of the main targets of these programs.
•    The number of villages electrified increased to 99,595 by March 2006, against 40,784 in 1991-92.

Constraints or challenges of Rural Electrification in Pakistan:

Small villages are far

•    Many of the small villages especially in KP and Baluchistan are far from transmission lines

High set up and maintenance costs

•    the cost of laying and maintaining transmission lines is high and is an extra burden on the country's major economic resources

Economically not feasible

•    It is not economically feasible to provide electricity to very small villages yet; the government has set limits so that in KP and Sindh villages with fewer than 1000 people and in Baluchistan fewer than 300 people will not be supplied.

Solution

•    In order to help solve the above problems electricity generation programs using bio-gas and solar energy are being tested.

The Himalayas in Northern Moutains



Introduction

•    The Himalayas are to the south of the Karakoram Range.
•    They run east to west.
•    They comprise
•    Siwaliks,
•    Lesser or Lower Himalayas and
•    Central Himalayas.

Location

The Siwaliks;

•    They are the low altitude (600 - 1200 meters) hills
•    They are located near Attock.

Lesser or Lower Himalayas;

•    The Lesser, or Lower Himalayas, are of medium altitude (1800 - 4500 meters)
•    They are represented by the Pir Panjal range.

Central Himalayas;

•    Moving north, the height of the mountains increases.

•    The mountain range, which is located between Pir Panjal Range and Karakoram Range, is called 'The Central Himalayas'.

•    This part of the Himalayas mostly lies in Kashmir.

Topography

•    The natural topography of this area is characterized by snow¬ capped, steep-sided peaks, with huge glaciers causing deep erosion, and by rich natural vegetation in the valleys. 

Climate

•    There is a severe climate in Himalayas
•    Winters are cold while summers are mild
•    The sever climate makes certain parts of the range extremely inhospitable so this region has a low population density.

Precipitation

•    The precipitation is mainly in the form of snow because of the high altitude

Drainage

•    In the upper regions of these valleys there are glaciers instead of rivers.

Agriculture

•    Agriculture is practiced
•    Cattle breeding are also common.

Impact on lives of people

•    A nomadic or semi-nomadic way of life is common
•    Settled way of live is also observed where climatic conditions pose no problems for living

Special Feature

•    Siwaliks are important for mining
•    Lesser Himalayas are of special interest to tourists, with some popular hill stations. For example Murree, Nathia Gali and Ghora Gali, etc are located there.
•    In Central Himalayas the highest peak is, Nanga Parbat, with a height of about 8126 meters

Biogas and Pakistan



Definition

•    It is produced from animal and plant waste.
•    Fermentation of cow-dung gives off methane gas

Uses

•    Methane gas is used for cooking, heating and other purposes

Potential benefits and challenges of Biogas in Pakistan

•    Biogas projects are in the process of development.
•    Although, biogas is a cheap source of energy, it means cow-dung can no longer be used as manure.
•    If this happens on a large scale it will aggravate the deficiency of a soil already lacking in organic nutrients.
•    It will increase air pollution because methane is a greenhouse gas

Biomass and Pakistan



Definition

•    Biomass refers to organic material, plants and vegetable matter, both living and decaying that can be used as fuel.
•    Most commonly, biomass refers to plant matter grown to generate electricity or produce biofuel.

Example of Biomass

Examples of biomass include;
•    Trees and grasses,
•    Agricultural residues (like used vegetable oils, wheat straw, or corn, sugar beets, grains, sugar-cane, and Wood waste like paper trash, yard clippings, sawdust or wood chips)
•    Methane that is captured from landfills, livestock, and municipal waste

Process for electricity generation

•    Numerous processes such as gasification, and fermentation, can tap into this energy source to produce energy available for human use.


Potential of Biomass in Pakistan

•    The use of biomass as fuel is not new to Pakistan.
•    The village women make patties of cow-dung, straw and clay to dry and use as home cooking fuel.

Disadvantages of Biomass

•    Unfortunately it is a relatively inefficient use of the biomass
•    It causes severe indoor air pollution
•    It causes adverse health effects such as lung and chest infections.

Geothermal and Pakistan



Definition

•    Geo means earth and thermal means heat
•    Geothermal power is the energy derived from the heat of the Earth's core.

Process

•    Geothermal energy is produced from Earth's heat absorbed in underground water (such as hot springs).
•    The holes are drilled into the land to pump out hot water.
•    This hot water or steam is used to drive turbines to produce electricity.

Advantages

•    It is renewable source of energy
•    It provides a constant supply
•    It is relatively pollution free
•    If properly developed, it can offer renewable and sustainable energy.

Disadvantage

•    It has high cost of construction of a power station
•    It has a high cost of maintenance
•    It has limitation to volcanic areas therefore it has the threat to power stations from eruptions and earthquakes.

Geothermal Potential in Pakistan

Plate margins

•    Geothermal resources of the world are within areas of crustal weakness such as plate margins and centers of volcanic activity.
•    Pakistan seems to have geothermal potential because a plate margin passes through Pakistan and it lies in an earthquake zone.

UN survey Report

•    According to a geotectonic framework survey conducted by United Nations and Italian experts, Pakistan has a potential of commercially exploitable sources of geothermal energy in the Himalaya region and areas in Baluchistan Plateau.
Presence of hot springs
•    The presence of a fairly large number of hot springs in different parts of the country has also been identified by some survey teams.
Study requirements for geothermal exploitation

Geothermal exploitation requires an integrated study based on:

•    identification of geothermal sites
•    estimation of the size of the resource and economic cost involved in exploitation of the resource
•    determination of heat content of fluids that will be discharged by wells in the geothermal field
•    After completing a positive feasibility study, geothermal projects may help to solve the energy problem of Pakistan.

Karakoram Range in Norther Mountains



Location

•    The meaning of Karakoram is black gravel
•    It is a mass of rock and ice
•    Extending for more than 400 km from Hunza to Shyok River
•    The western end of this range lies in Pakistan

Topography

•    The range runs east-west
•    It has deep, narrow valley and sharp peaks thus forming a very rugged landscape.
•    The average height of the mountains is about 6000 meters.

Climate

•    The sever climate makes the Karakoram extremely inhospitable so this region has a low population density.
•    The mountain passes are open only for half of the year, during summers

Precipitation

•    The precipitation is mainly in the form of snow because of the high altitude

Drainage

•    In the upper regions of these valleys there are glaciers instead of rivers.

Agriculture

•    Agriculture is practiced in those valleys where water is plentiful
•    Apples, barley and millet are the main products.
•    Cattle breeding are also common.

Impact on lives of people

•    A nomadic or semi-nomadic way of life is common

Importance of Location: From a strategic and an economic viewpoint




Scope of Land:

•    Pakistan enjoys a key position in South Asia
•    There are few links by land to the north and north-west because of the large mountain ranges and the climate
•    Khyber Pass provides a route to Afghanistan
•    Karakoram Highway makes communication with China
•    The areas to the north and north-west are landlocked; thus Pakistan's seaport of Karachi can also serve these areas
•    CAS Republics possess untapped power resources such as mineral oil and natural gas, which can easily be transported through Pakistan and Iran to the South Asian and South East Asian countries by constructing pipelines
•    These projects could bring enormous economic benefits to Pakistan such as transit revenue, power resources for various industrial, commercial and domestic uses

Scope of Sea:

•    Pakistan's coastline on the Arabian Sea is in a central position for trading by sea both with South Asia and the Far East and beyond and with the Middle East to the west

Scope of Air:

•    Air routes between west and east pass through Pakistan because of this central position.
•    Thus Jinnah Terminal, Karachi, could have immense importance as an international airport though it is greatly under-used with Dubai taking over Karachi's natural role

Scope of CPEC:

•    During recent years China has emerged as an economic power and a trading giant in the international market.
•    Pakistan, being the immediate neighbor of China, has increased trade with China.
•    The inflow of Chinese goods to Pakistan's domestic market on low prices has increased competition with our domestic industry
•    Construction of CPEC is game changer for Pakistan

Tidal Power and Pakistan




Definition

•    It is a renewable method of producing electricity by using the movements of the tides.
•    The tide comes in and out once, and usually twice, in every 24 hours.
•    This is due to the gravitational pull of the moon.

Process of electricity generation

•    Along with Tidal power generator a barrage (dam) is built across a river estuary (inlet) and water is pushed through a turbine and generator (fitted into tunnels in the barrage) as the tide comes in and goes out.
•    For shipping to be able to pass, locks are built into the barrage which can be opened to allow the safe passage. 


Benefits of Tidal Power

•    There are obvious benefits to this type of tidal power generation for example the barrage can act as a road bridge, and the nearby coastline is protected from powerful waves.

Advantages of Tidal Power

•    It is renewable
•    It provides constant supply
•    It is relatively non pollutant

Challenges

•    Such schemes would be very expensive to build
•    It would destroy important wildlife habitats
•    It could disrupt local shipping if arrangements are not made for it.

The Tidal Power Potential in Pakistan

•    The power resource potential of the Indus Deltaic Creek System is a great asset for future energy supply in Sindh, Pakistan.
•    The National Institute of Oceanography (NIO) shows encouraging results in its initial survey.
•    The creek system of the Indus delta extends over an area of 170 km.
•    Tidal water flows in these creeks with high velocity which is a favorable requirement for the extraction of energy from tidal currents.

Wave Power and Pakistan



Definition

•    A wave power turbine uses changes in air pressure caused by the waves to turn the turbine and generate electricity.

Process of electricity generation

•    Waves have exceptionally high energy levels.
•    Wave motion can be used to compress air to drive a turbine to generate electricity.


Potential for Wave Power in Pakistan

•    Pakistan has about 1000 km long coastline.
•    The Makran coastal areas have strong wave energy, which could be harnessed for the generation of electric power for rapidly developing coastal cities like Gwadar
•    However, wave power is an expensive option for Pakistan.
