Pakistan is facing acute shortage of energy. with 7% increase of its economy this short fall soon to slow down its economic growth and will shatter its dream to become one day a developed country.

Most of its energy demand is being met with either Hydro power or thermal units. Pakistan is spending a very large amount  of foreign exchange to purchase the furnace. The gas reserves already start depleting and oil markets are sky rocketing. To overcome this shortage Government take a initiative to investigate Alternate energy resources in  Pakistan developed Alternate Energy Board AEDB . The Board is headed by Retd Air Marshal Shahid  Hamid. identified 50,000 MW energy potential from wind resource

Pakistan is blessed with a large resource of wind corridor. Although Pakistan meteorological Department was gathering wind data for quite long time But recently United States provided wind energy map for Pakistan (pak_wind.pdf) which confirms a strong wind corridor in Sind coastal area.

AEDB issued about 80 LOI to the investors  (List of LOI holders )to develop 50 MW wind farms. Out of which 15 are already issued the land and feasibility reports and financial closings are in progress.

The following is a brief road map for developing a wind form

1. submission of proposal by sponsor
2. Review of proposal by AEDB
3. Posting of Bank Guarantee
4. issuance of letter of intent ( LOI )
5. Feasibility study
6. Generation License
7. Tariff Determination
8. Submission of Performance Guarantee
9. Tariff determination by NEPRA
10. Submission of performance guarantee
11. Issuance of Letter of support

The first requirement of conducting feasibility study is to install a wind mast. The three major manufacturers of wind data are listed below . This document explains the method for installing weather station.

Geological, seismic. tectonic and environmental studies will be required along with Digital mapping and topography of the site for preparing a bankable feasibility study. A confirm  EPC cost will also be needed for calculation of tariffs.

Some large manufacturers of wind turbines are given below

 

1.	Vestas,   vestas denmark (27.9%)
2.	GE Wind, US (17.7%)
3.	Enercon,Germany (13.2%)
4.	Gamesa, Spain (12.9%)
5.	Suzlon, India (6.1%)
6.	Siemens, Denmark (5.5%)
7.	Repower, Germany (3.1%)
8.	Nordex, Germany (2.6%)
9.	Ecotecnia, Spain (2.1%)
1	Mitsubishi, Japan (2.0%)

WIND ENERGY BASICS

Power developed by a wind turbine can be mathematically shown in following formulae

1/2xdensity of air x effective area of rotor blade   x cube of speed of wind

The lay out and designing of the wind form can be done by wind energy planning and project software available in market in a reasonable price . One such software is Wind Pro which is a very convenient tool for project management.

Environmental Protection agency require a detailed environmental impact study of the project. the following issues should be discussed detail

1. Birds collision or alteration of their migration routes

2. Noise impact

3. flickering
