Transmission

Since FY 09, K-Electric has invested c. USD 500 Million in expanding and rehabilitating its transmission network, including addition of new grid stations and transmission lines. K-Electric’s transmission system comprises of 1,253.9 km of 220kV, 132kV and 66kV lines, with 64 grid stations and 148 power transformers. In recent years, KE has taken major steps towards enhancing the transformation capacity and improving its reliability.

617 11kV Switch installations/replacements have been carried out since July 2014 across various grid stations, as part of a comprehensive effort to ensure optimal performance.

ISO 9001:2015 QMS Certification:

The following Transmission network departments are certified under ISO 9001:2015 Quality Management System:

  • Project Implementation
  • Grid System Maintenance
  • System Operation
  • SCADA Maintenance

TP-1000:

To cater the growth in demand and service additional capacity, KE is committed on further upgrading, enhancing and expanding its transmission infrastructure.

TP-1000 is a c. USD 450 Million transmission enhancement project which will add over 1,000 MVAs to our network, enabling the utility to transmit additional c. 800 MW while improving power reliability and voltage stability. The project will include new grid stations and the addition of a Disaster Recovery Center.

In this regard, major part of the Civil and Electrical Design has been completed along with initiation of civil works at majority of the sites. Additionally, manufacturing and delivery of major equipment, such as all 220 kV GIS Bays, 132 kV GIS Bays, 6 x 250 MVA Auto transformers and 34 x 40 MVA Power Transformers for all of the targeted grids have also been completed. Furthermore, 6 x 40 MVA Power Trafos at Hospital, Maymar, Johar, Landhi, RECP and Valika Grid Stations have been energized successfully well ahead of time.

Further, the transmission line design for major material has been approved and type test of 220kV & 132kV cables has also been carried out. Additionally, manufacturing of various type of Power Cables, Poles and Towers is also under progress, a major portion of which is already delivered and under erection / concreting.
