In order to cater for the increased demand of electricity during summer season, National Transmission and Dispatch Company Ltd (NTDC) is all set to overcome the system constraints on identified 500 and 220 kV grid stations across the country. A 250 MVA transformer has been added in 220 kV Ghazi Grid Station that would end overloading of system besides providing uninterrupted power supply to LESCO consumers with improved voltage level.

NTDC has devised the System Constraints Removal plan consisted of three phases. In the first phase, a 450 MVA transformer has been added and energized at 500 kV Jamshoro grid station in January 2020 to overcome the system overloading during minimum power generation of Wind Power Plants (WPPs).

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 to be completed in shortest possible time.

NTDC has already managed to resolve the constraint issues successfully in Islamabad, Rawalpindi and Faisalabad by adding of a 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 a 600 MVA transformer at 500 kV Gatti grid station has played a vital role in system stability and managed to reduce overloading substantially. The 500 kV Gatti grid station in Faisalabad is one of the major stations of the country's transmission network with overall capacity of 2400 MVA. The grid station is feeding LESCO and FESCO areas as well.
