ISLAMABAD - The Central Power Generation Company (CPGC) has decided to shut down power generation from four outdated power plants located at Guddu (Sindh) on permanent basis, which in total have the capacity of 320 megawatts, it was reliably learnt here on Thursday.Sources in National Electric Power Regulatory Authority (NEPRA) informed TheNation that Central Power Generation Company in its request through an application submitted to the NEPRA has asked the regulatory authority to close down the power generation from Guddu units I, II, III, and IV, which are operational since 1974 to add to the electric power to meet the power demands of the country. They said though these four power plants have completed their life cycle in 2006 yet they were busy in power generation. Due to continuous power generation from these plants, precious gas has been wasted while electric power is being generated from them to meet the widening demand and supply gap at cost of pressed masses and natural gas reserve of the country as well. Sources further told that the Central Power Generation Company (CPGC) in its plea has sought the approval of NEPRA only to permanently close down these four power plants through introducing amendments in the licence of the company.  It is, however, pertinent to mention that CPGC has decided to install a new 747 megawatt combined cycle power plant at Guddu in Sindh province in order to enhance the power production for meeting future requirements and Finance Ministry has already given its approval over the request of Central Power Generation Company Limited seeking Rs 3.60 billion worth cash development loan for 747 mw Combined Cycle Power Plant (CCPP) at Guddu in order to enhance country's power generation. The power plant will help the government in coping with increasing demand of electricity and will enhance power supply to this area, making the supply more reliable and improve the quality of service. The plant, which will be installed within the premises of existing Guddu power plant complex in Kashmore district of Sindh will also create employment opportunities.According to details, the project will comprise a 747 mw Combined Cycle Power Plant consisting of two gas turbines of 243 mw each; two heat recovery steam generators and one steam turbine of 261 mw and associated equipment. The existing plant includes 640 mw steam turbine units consisting of two 110 mw units and two 210 mw units, a 600 mw Combined Cycle Power Plant and another 415 mw Combined Cycle Power Plant, with a total plant capacity of 1,655 mw.The existing steam and combined cycle units can run both on gas and fuel oil. However, fuel oil is used only during interruptions in gas supply. There will be no additional gas required for the new 747 mw plant and existing supply will be used for power production.
