LAHORE              -               National Transmission and Despatch Company Ltd (NTDC) has decided to upgrade infrastructure for ensuring uninterrupted electric supply during coming summer. 250 MVA transformer has been added in 220kV Ghazi Grid Station for providing uninterrupted power supply to LESCO consumers with improved voltage level. NTDC has devised System Constraints Removal Plan that will be implemented in phases.. In its first phase, a 450 MVA transformer has been added and energized at 500 kV Jamshoro grid station in Jan 2020 to overcome overloading of the system during minimum power generation of wind power plants (WPPs). The NTDC spokesman said that the augmentation work on 500 kV Bhikki-New Lahore transmission line, 220 kV Ravi-Lahore transmission & 220 kV Ravi-Shalamar transmission line is also in progress which will be completed in shortest possible time. NTDC has already managed to resolve the constraints issues successfully in Islamabad, Rawalpindi and Faisalabad with addition of 750 MVA transformer at 500 kV grid station Rawat which resulted in smooth power supply to IESCO consumers of Islamabad, Rawalpindi and Chakwal without overloading of the system. The said grid station has become an important and major hub of power dispersal with overall capacity of 2850 MVA. Likewise, installation of 600 MVA transformer at 500 kV Gatti grid station has played a vital role in system stability and managed to reduce overloading considerably.
