To overcome the frequent power breakdown that costs the government and private sector billions of rupees, the Pakistani government has planned a power transmission enhancement project (PTEP).
The project comprises 10 sub projects of 500-kV and 220-kV substations and transmission lines worth Rs 20 billion, including foreign exchange component (FEC) Rs 13.330 billion.
Successful implementation of the different projects would improve the system security, stability, loss reduction and reliability of the power system across the country, as reported in the Daily Times in Pakistan.
The project is proposed to be funded from Asian Development Bank loan with 80 percent of the project and 20 percent from NTDC’s own resources. The main objective of this project is the enhancement in the power transmission system by extension, augmentation and expansion of the existing 500-kV and 220-kV transmission system of National Transmission and Dispatch Company (NTDC) to meet the requirements of growth of power demand in the country.
The officials in the planning division said that in recent years, as economic activities picked up in the country, there was a quantum jump in the power demand. As a result, the NTDC system has been subjected to stress and congestion at various strategic locations. Consequently, the system was stretched beyond capacity and this caused overloading, which resulted in outages. This had necessitated the extension, upgrading and augmentation of the existing grid stations and installation of new substations and transmission system, he maintained.
The project includes: 500-kV Ghazi Barotha substation, augmentation of 220-kV Ravi substation, and installation of SVCs at 220-kV Quetta, 500-kV DG Khan substation, 220-kV Okara substation, 220-kV Toba Tek Singh substation, 220-kV Loralai substation, 220-kV Nowshera substation, 220-kV Rohri new substation (for dispersal of power from Engro chemical IPP near Mari/Dahrki) and last one dispersal of power from Jarwar CCPP (132 KV Sadiqabad substation extension and new transmission line).
