Wind power en­ergy in Pak­istan

The wind of change is blow­ing and the world has now mov­ing to­wards new tech­nolo­gies out of which re­new­able en­ergy is im­por­tant one. Keep­ing in view the com­mer­cial and in­dus­trial consumption of oil and gas ev­ery­one is con­scious to have some al­ter­nate re­source for en­ergy pro­duc­tion. Wind is also one of the re­sources for the power gen­er­a­tion. A wind tur­bine is a de­vice that con­verts ki­netic en­ergy from the wind, also called wind en­ergy, into me­chan­i­cal en­ergy; a process known as wind power. If the me­chan­i­cal en­ergy is used to pro­duce elec­tric­ity, the de­vice may be called wind tur­bine or wind power plant. If the me­chan­i­cal en­ergy is used to drive ma­chin­ery, such as for grind­ing grain or pump­ing water, the de­vice is called a wind­mill or wind pump. Sim­i­larly, it may be called wind charger when it is used to charge bat­ter­ies.

The re­sult of over a mil­len­nium of wind­mill devel­op­ment and mod­ern en­gi­neer­ing, to­day’s wind turbines are man­u­fac­tured in a wide range of ver­ti­cal and hor­i­zon­tal axis types. The small­est turbines are used for ap­pli­ca­tions such as bat­tery charg­ing or aux­il­iary power on boats; while large grid con­nected ar­rays of turbines are be­com­ing an in­creas­ingly im­por­tant source of wind power‐pro­duced com­mer­cial elec­tric­ity.

Pak­istan is also fac­ing elec­tric­ity short­fall since last decade, to over­come this is­sue a step to­wards re­new­able en­ergy is taken and gov­ern­ment showed in­ter­est, a sur­vey re­port had been is­sued show­ing that Pak­istan has an ideal wind cor­ri­dor in Islamabad, Thatta and Karachi re­gion. Min­i­mum wind speed re­quired to run the tur­bine ranges from 3~4 km/s; it’s our for­tune that our wind cor­ri­dors re­ceives 6~7.5 m/s which is an ideal wind for wind turbines. Sur­vey reports have shown that Pak­istan can pro­duce 300,000 MW elec­tric­ity from wind and so­lar en­ergy, whereas ac­tual re­quire­ment of Pak­istan is es­ti­mated at 22,000 MW.

Pak­istan’s first 50 MW Wind Farm Project was started in Jham­pir (Sindh) by Zurlo En­erji en­gi­neer­ing a Turk­ish com­pany and com­pleted five wind turbines out of which one was unin­stalled. Ca­pac­ity of each tur­bine was 1.2 MW ; cur­rently four turbines are op­er­a­tional so far gen­er­at­ing 4.8 MW. Un­for­tu­nately the project stands closed due to some lo­cal is­sues as well as fi­nan­cial matters.

A 49.5 MW wind farm project by Fauji Fer­til­izer Com­pany En­ergy Lim­ited (FF­CEL) was awarded to Nordex (Ger­many) and Descon En­gi­neer­ing Ltd. (Pak­istan). Both com­pa­nies started the project with full con­cen­tra­tion, un­for­tu­nately around 50 armed lo­cal in­trud­ers se­verely beaten the project team caus­ing the sus­pen­sion of project ex­e­cu­tion for three months. In July 2011, the work was re­sumed. In­stal­la­tion of 33 No’s of wind turbines (1.5 MW each) was suc­cess­fully com­pleted in July 2012 and the project is now in com­mis­sion­ing phase and will be op­er­a­tional soon.

Zurlo En­erji has again started 50.4 MW wind farm project at jham­pir at the stage when FF­CEL wind farm project was re­sumed. Zurlo En­erji is in­stalling the Ves­tas wind turbines man­u­fac­tured by Den­mark; each tur­bine is ca­pa­ble of pro­duc­ing 1.8 MW elec­tric­ity. Al­most 15 No’s of turbines have been erected so far and re­main­ing will be com­pleted in near fu­ture.

Two more wind farm projects of 50 MW each hav­ing 40 No’s of wind turbines (FWEL I & FWEL

II) have started in Gharo area, both projects are again awarded to Nordex and Descon

En­gi­neer­ing Ltd. 20 No’s of turbines will pro­duce 50 MW (2.5 MW each) ex­pected com­ple­tion is first quar­ter of 2014.

The story doesn’t end here, it’s ac­tu­ally the start of a rev­o­lu­tion, and there are plans of us­ing max­i­mum wind en­ergy for elec­tric­ity gen­er­a­tion. Al­ter­nate En­ergy Devel­op­ment Board (AEDB) has so far al­lo­cated land to 18 wind IPPs (In­de­pen­dent Power Pro­duc­ers), 13 have sub­mit­ted fea­si­bil­ity reports and elec­tric­ity gen­er­a­tion li­cense is is­sued to 06 IPPs, a queue of projects will be launched very soon.
