On 1 September, the 660kV High-Voltage Direct Current (HVDC) Matiari-Lahore transmission line, the China-Pakistan Economic Corridor (CPEC) project in the power evacuation and transmission sector, started commercial operations on its scheduled date. In this regard, a ceremony was held at WAPDA House Lahore, attended by Managing Director NTDC and President and CEO of PMLTC and other representatives from both companies.

The Managing Director of the National Transmission and Despatch Company Ltd (NTDC) said, “It is a matter of great importance that the country finally succeeded in having the first and the biggest HVDC transmission line to evacuate 4,000 megawatts from power plants in the south in direct current (DC) mode, transport and transmit it to Lahore after converting it into alternate current (AC) mode and finally feed it to the distribution systems in the load centres in Punjab,” adding, “With the provision of the HVDC line, there are now meagre chances of blackouts, breakdowns etc due to system constraints since the entire NTDC transmission and dispatch system has attained stability.”

The Project: Matiari-Lahore HVDC Transmission Line
The Matiari-Lahore transmission project is an 878km-long, 660kV high voltage direct current (HVDC) transmission line and is the first HVDC line and the first private sector transmission project developed in Pakistan. The USD 1.65 billion transmission project has been developed on a build, own, operate and transfer (BOOT) basis by the State Grid Corporation of China (SGCC) through the special purpose company Pak Matiari-Lahore Transmission Line Company (PMLTC). On the completion of 25 years of operations, the ownership of the transmission line will be transferred to the NTDC.

The 878km transmission link stretches from Matiari in the province of Sindh to the Nankana Sahib district near Lahore and is capable of transmitting up to 4GW of electricity. More than 60 per cent of the line route lies in desert areas to avoid settlement issues and conflicts associated with the securing of right-of-way. The Matiari-Lahore transmission link is a bi-pole HVDC line with two converter stations at Matiari and Lahore, additionally, the project also involves three repeater stations and two grounding electrode stations. The Matiari converter station will receive power supply from the Port Qasim power and the Hubco power plant. Additionally, it will also be connected to the Engro Thar coal power plant and the SSRL Thar Block-1 power.

The Economic Coordination Committee in July 2017, approved the Security Package Documents; Implementation Agreement (lA) and Transmission Services Agreement (TSA), which were later executed in May 2018.
