The incumbent government spent more than Rs 49 billion in up-gradation of electricity transmission lines and during summer as many as 25,000 MW electricity was transmitted through the system, which was only 18,000 MW in 2018- the last year of the PML-N government. Sources told APP on Friday that the previous government did not pay attention to up-grade the transmission network and their focus remained on setting up power plants mostly based on imported expensive fuel. The system could not transmit more than 18,000 MW despite availability of generation capacity during peak summer season due to paying no proper attention to the up-gradation of the transmission system, they said. However, the incumbent government made heavy investment both in the transmission and distribution system to remove the constraints and enhanced the capacity over 4000 MW during the last 3 years. Meanwhile, the power regulator National Electric Power Regulatory Authority (NEPRA) has approved the Competitive Trading Bilateral Contract Market (CTBCM) Model via its determination issued on December 5, 2019. The approval of CBTM by NEPRA has paved the foundation for the establishment of a competitive whole- sale electricity market in Pakistan.
