September 09, 2019 Fantasy
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

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.
• 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.

Evaluation of developing wind power in Pakistan
Advantages
Abundant
• Wind is a renewable resource. It will never deplete.
Environment friendly
• It is environment friendly unlike fossil fuels.
Utilized independently
• Wind energy has the advantage that it can be utilized independently, and deployed locally in rural and remote areas of Pakistan.
Good for rural electrification
• The locations far away from the main grid are suitable for generating wind electricity. It is very expensive to connect small villages to the national electric grid because of the huge infrastructure costs.
Attracts tourism
• Wind farms are interesting features of landscape attracting tourism.
Available in different sizes
• Wind turbines are available in a wide range of sizes depending on the requirement.
Solution to energy crisis
• Wind power can help to solve Pakistan's energy problems thus leading to industrial and agricultural expansion.

• Wind power can help to solve Pakistan's energy problems thus leading to industrial and agricultural expansion.
Increase in job opportunities
• Wind farms provide a source of income for farmers and may attract small industries to rural part of Pakistan where job opportunities are limited.
Disadvantages
Expensive
• Wind turbines are expensive to build thus increasing the burden on the economy.
Inconsistent
• The strength of the wind is not constant and varies from zero to storm force.
• This means that wind turbines do not produce the same amount of electricity all the time.
• They automatically stop working when there is a storm.

• They automatically stop working when there is a storm.
Hurts fragile balance of ecosystem
• Wind turbines can kill birds and bats thus harming the fragile balance in ecosystems.
Burden of scarce land resources
• Large wind farms are needed to provide entire cities with enough electricity thus causing a burden on scarce land resources.
Built only in specific spaces
• Wind farms can be developed only in coastal areas and mountainous region with high wind speeds.
• 7500 turbines are needed to produce the same amount of electricity as one nuclear power station.
• 7500 turbines are needed to produce the same amount of electricity as one nuclear power station.
Wind Power in Pakistan
Suitable coastline
• The coast of Pakistan is about 1000 km long and has a population of about 10 million people.
Supportive strong winds
• High wind is available nearly all year round in these areas.
• It is observed that the annual wind speed in Baluchistan and Karachi is such that it can be used to generate electricity.
