KESC Power Sta­tion-ii nears com­ple­tion

Enterprise - - Infocus -

Karachi Elec­tric Sup­ply Com­pany will achieve Gross De­pend­able Gen­er­a­tion Ca­pac­ity of 2052 megawatts with the early com­ple­tion of the 560-MW Bin Qasim Power Sta­tion-ii. How­ever, KESC’S re­quest for sup­ply of the al­ready ap­proved ad­di­tional 130MMCFD gas quota for the new plant is still pend­ing with the Gov­ern­ment. This is the main rea­son for de­lay in the launch of the util­ity’s op­ti­mum power pro­duc­tion. The project is worth 450 mil­lion dol­lars and will en­hance KESC’S power gen­er­a­tion ca­pac­ity by 30 per­cent.

Ar­shad Zahidi, Chief Strat­egy Of­fi­cer, Gen­er­a­tion and Trans­mis­sion, said that the Com­bined Cy­cle Power Project is al­most ready to gen­er­ate 560 megawatts with the ex­e­cu­tion of the project hav­ing en­tered final phase, but it re­quires an un­in­ter­rupted sup­ply of 130 MMCFD gas, al­ready ap­proved and com­mit­ted by the Fed­eral Gov­ern­ment, for its Base Load Op­er­a­tion. Con­sis­tent gas pres­sure and calorific value are also very crit­i­cal for op­er­at­ing the plant at op­ti­mum level. How­ever, he said, very low or some­times zero gas pres­sure is be­ing pro­vided to the plant so far.

Ghufran Atta Khan, Chief Mar­ket­ing and Com­mu­ni­ca­tion Of­fi­cer, su­per­vised a me­dia visit to the plant. Also present on the oc­ca­sion were other top of­fi­cials of KESC in­clud­ing Ab­bas Hus­sain, Project Man­ager, Syed Zubair Ahmed, Project Di­rec­tor, Tahir Ali Khan, Di­rec­tor BQPS-II, and a rep­re­sen­ta­tive of Harbin, China.

A de­tailed brief­ing was pro­vided to the me­dia over the need of reg­u­lar sup­ply of 130 MMCFD of nat­u­ral gas to the plant which would make Bin Qasim Com­plex the largest ther­mal power sta­tion in the coun­try. Ar­shad Zahidi said that KESC had adopted a sin­gle di­rec­tion strat­egy re­gard­ing fuel re­source of the project. “We are al­ready ex­e­cut­ing our coal con­ver­sion project at BQPS-I. But the gov­ern­ment com­mit­ted and ap­proved ad­di­tional quota of 130 MMCFD nat­u­ral gas for the BQPSII and an im­me­di­ate sup­ply of this quota was es­sen­tial to launch the project with­out de­lay.”

Zahidi pointed out that in spite of the con­di­tions in Pak­istan, world lenders like In­ter­na­tional Fi­nance Com­mis­sion and Asian De­vel­op­ment Bank, be­sides a lo­cal banks con­sor­tium, had trusted the per­for­mance and cred­i­bil­ity of KESC and had re­leased their long held up loan fa­cil­i­ties for the project. More­over, KESC’S 180 MW Ge-jen­bacher Gas En­gines Project has been awarded the “Best Fast Track Project (Sil­ver Award)” and “Best Plant in the Re­gion” ti­tle by Asian Power Mag­a­zine.

The Chief Strat­egy Of­fi­cer said that at present all three GE Frame-9 Gas Tur­bines bought from France with a ca­pac­ity up to 120 MW each, water treat­ment fa­cil­ity, NG com­pres­sors and fire sys­tem of the new plant have been com­mis­sioned and are func­tion­ing sat­is­fac­to­rily. The 180-MW steam tur­bine from Harbin, China, has also been com­mis­sioned and is un­der test­ing which is sched­uled to be syn­chro­nized this month.

The me­dia team was also in­formed that the plant has the largest power sta­tion water treat­ment plant in the coun­try that meets the req­ui­site stan­dards and has the qual­i­ties of a re­verse os­mo­sis plant that min­i­mizes ef­flu­ents, zero water im­port re­quire­ments and of­fers min­i­mal tem­per­a­ture dis­rup­tion to sea water en­vi­ron­ment. He said the Chi­nese con­trac­tors had added tremen­dous value to the project.

Three en­gines with ca­pac­ity to pro­duce two megawatts each have been ded­i­cated to pro­duce two-hour start-up electricity in case of a black­out. The plant has an Aux­il­iary Boiler that en­ables rapid Steam Tur­bine Start up. Ther­mal ef­fi­ciency of the plant is 51 per­cent which is the high­est com­bined cy­cle ef­fi­ciency in Pak­istan.

Zahidi also talked about the over­all en­hance­ment of power gen­er­a­tion and trans­for­ma­tion ca­pac­ity and up­grad­ing of trans­mis­sion net­work of the util­ity ever since Abraaj Cap­i­tal took over KESC’S man­age­ment con­trol in Septem­ber 2008.
