With a vision to supply uninterrupted electricity and to bridge the gap between valued customers and K-Electric, a significant investment is made in recent years. Major initiatives were taken in areas of Capacity Enhancement, Grid station and Transmission line augmentation and rehabilitation.

Transmission System Enhancement

Owing to the investment made in transmission system, the MVA capacity increased by around 3000 MVA and the overall transmission losses improved by 3.17% points since the start of FY09.

Continuing with its mission of keeping Karachi illuminated, by far in FY23 KE has enhanced its transmission capacity by 100MVA with addition of new power transformer at Agha Khan grid and Landhi grid, alongside enhancement in existing grids taking total transformation capacity to 6,903MVA. A new 132kV Site – Haroonabad circuit – II is also energized increasing the reliability of the system. Furthermore, projects including reconductoring of transmission lines and RTV coating of insulators are in progress that aim to improve system reliability.

Initiatives

To manage the growing power demand of the metropolis while ensuring optimal utilization of transmission infrastructure and reliability in power supply, KE has developed long term transmission expansion plan till FY30.

Furthermore, considering the surplus capacity scenario in the National Grid, KE is in the process of setting up of new grids and interconnection works which would enable drawl of additional power from the National Grid in addition to 1,100 MW currently being evacuated. In this regard, the process for setting up of new grid at 500kV level is in progress. Whereas the construction of new 220 kV Dhabeji Interconnection is in full swing. Upon completion of these grids and interconnection works, KE will be able to import additional power from the National Grid which will enable KE to manage the demand in upcoming years alongside enhancing system reliability.

In addition to above, as per KE’s plan to bring a substantial change in the rural parts of its service territory by upgrading its infrastructure in these areas to meet the increasing load profile and to help economic expansion, KE is carrying out large-scale rehabilitation project of existing 132kV and 66 kV transmission lines in Hub, Vinder, Uthal and Bela regions on an accelerated pace. Phase-I of the project is at the verge of completion with 98.25%, whereas Phase-II stands at 93.15%, and both the phases are expected to be completed by the end of FY23.

Moreover, under flagship project of 900MW BQPS-III, upgradation of transmission network is planned that includes augmentation of two critical load grids and two generation interconnection grid stations. One load grid (New Landhi) has been energized which will not only improve reliability of the network but will also help catering new industrial load growth. Also, the new interconnection at KTPS will evacuate power of KPC on 132kV system rather than on 220kV viz-a-viz corelating embedded generation and improving the network efficiency.
