HVDC operationalized in Pakistan

ISLAMABAD, Sep 2 (Gwadar Pro)– Matiari-Lahore high voltage direct current (HVDC) transmission line project was operationalized on September 1, 2021.

The Managing Director of Pakistan’s National Transmission and Dispatch Company (NTDC) Engr. Azaz Ahmad and Ms Zhang Lei, President and CEO of PMLTC jointly inaugurated the country’s first ever High Voltage Direct Current (HVDC) transmission line project  on Wednesday.

According to a press note issued by National Transmission and Despatch Company, the flagship project under CPEC has achieved its commercial operation date successfully as per the agreed timeline between National Transmission and Despatch Company Ltd (NTDC) and Pak Matiari-Lahore Transmission Line Company (PMLTC).

Managing Director NTDC Engr. Azaz Ahmad said “The first ±660 kV HVDC Matiari Lahore Transmission Line will bring stability to the NTDC transmission network after having crossed many bridges.”  

It worth mentioning that engineers performed as many as 8 power tests on different voltage levels successfully.

 “The last test, Trial Operation (168 hrs) and Capability Demonstration Test (06 hrs) (A8:) had been successfully completed on August 18, 2021,” read the statement issued by Pakistani authorities on Wednesday.

The 878 kilometers 4000 MW project has been completed by Pak-Matiari Lahore Transmission Company (Pvt) Limited, on a Built-Own-Operate-Transfer (BOOT) basis for a term of 25 years. According to Pakistani authorities, the project will evacuate power from the new generating units located in the south including Thar coal-based projects.

HVDC technology is a maiden addition in the national grid of the country, though it’s been widely used for a long time around the world, and there is a need for long-distance high-power transmission from generating stations in the far-flung areas to densely located load centers.

"The power plants built under CPEC hold immense importance" for the country as they have largely solved the serious electricity shortage in Pakistan, bringing advanced technology and creating job opportunities,” the Minister said last week.

Not only that China helped Pakistan produce electricity, but also helps Pakistan improve Pakistan’s power distribution system.

 “HVDC project is a boon for the country's power sector because it will save energy consumption and transmit cheap electricity from CPEC's southern power plants to the northern load centers of the country,” Hammad told journalists last month.

“It will help Pakistan address the issues of energy shortage and inflated price of electricity," he added.

CPEC's southern power plants and the transmission line project, will ensure the supply availability, stability and security, supporting the industrialization process in the country, the minister said. 

“Pakistan’s electricity distribution system is old and fragile. Above 18 percent of the country's electricity gets wasted due to this decades old transmission lines, but HVDC is going to transform Pakistan’s electricity distribution system on modern lines,” a senior official said.
