Karachi Electric Supply Company achieves Gross Dependable Generation Capacity of 2052 Megawatts

Karachi: Karachi Electric Supply Company has achieved Gross Dependable Generation Capacity of 2052 Megawatts with the soon upcoming completion of 560-MW Bin Qasim Power Station-II, but KESC’s request for supplying the already approved additional 130MMCFD gas quota for the new plant is still pending with the Government, the main reason for delay in the launch of its optimum power production. The project is worth 450 million dollars and it has enhanced KESC’s power generation capacity by 30 per cent.

KESC on Monday organized a detailed visit and briefing for a team of media persons at the new BQPS-2. Mr. Arshad Zahidi, Chief Strategy Officer, Generation and Transmission, informed media 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, and the 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.

Mr. Ghuffran Atta Khan, Chief Marketing and Communication Officer, supervised the media visit to the plant. Also present on the occasion were other top officials of KESC including Mr. Abbas Hussain, Project Manager, Syed Zubair Ahmed, Project Director, Mr. Tahir Ali Khan, Director BQPS-II, and a representative of M/S Harbin, China, who guided the media visit to the country’s largest under construction power plant of its kind and explained the functioning its various sections.

Media persons were briefed in detail 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. To a questioner, Mr. Zahidi told that KESC had not just 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 BQPS-II and an immediate supply of this quota was essential to launch the project without delay,” he stated.

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

Mr. Zahidi said that at present, all three GE Frame-9 Gas Turbines bought from France with capacity up to 120 MW each, water treatment facility, NG compressors and fire system of the new plant have been commissioned and functioning satisfactorily.

The 180-MW steam turbine from Harbin, China, has also been commissioned and is under testing, scheduled to be synchronized this month. Media persons were also informed that the plant has the largest power station water treatment plant in the country that meets standards; and has the qualities of reverse Osmosis plant that minimizes effluents, zero water import requirements; and minimal temperature disruption to sea water environment. He said that Chinese contractors have added tremendous value to the project.

Mr. Zahidi disclosed that the BQPS-II has Black Start capability to avoid system black out in case of NTDC breakdown as experienced during July 2009 episode. Three engines having capacity to produce two megawatts each have been dedicated to produce two-hour starting up electricity in case of a black out. The plant carries the Auxiliary Boiler that enables rapid Steam Turbine Start up. Thermal efficiency of the plant is 51 per cent which is highest combined cycle efficiency in Pakistan.

Mr. Zahidi also briefed media persons on the overall enhancement of power generation and transformation capacity and upgrading of transmission network of the utility ever since Abraaj Capital took over its management control in September 2008. While 1010 MWs have been added in KESC’s installed power generation capacity from January 2009 to March 2011 by construction of new power plants, the existing fleet efficiency has been improved by over 10 per cent through replacement of old machines with highly efficient machines, timely and digital annual maintenance and overhaul of Bin Qasim Power Station’s old units and by optimum dispatch of electricity. Reliability of the system has been improved by reducing unit tripping by 33 per cent and 31 reduction in un-served energy.

On the other hand, 673 MVA have been added to KESC’s transformation capacity through construction of eight new grid stations, installation of 16 new transformers at existing grid stations and adopting of Creek City Grid from builder.

A total of 31.5 kilometer new transmission lines have been laid down enhancing the network from 1186 to 1218.5 kilometers, while 124 kilometer extra high tensions lines have been rehabilitated. With addition of 18 new circuits to the network the total number of circuits has come to 118. With that, transmission losses have been reduced from 4.19 per cent in September 2008 to 1.45 per cent in November 2011.
