ISLAMABAD: National Electric Power Regulatory Authority (Nepra), in its State of Industry (SoI) report 2020 maintains that the performance of Karachi Electric (KE) has worsened on recovery and losses in 2019-20 as compared to 2018-19.
According to the report, the total electricity generated by KE through its own power plants declined to 10,358 GWh during FY 2019-20 compared to the previous year's electricity generation of 10,727 GWh, showing a decrease of 369 GWh.
During FY 2019-20, KE purchased 8,169.68 GWh electricity from external sources including 1,862.68 GWh from IPPs, 193 GWh from KANUPP, 153 GWh from two solar power projects, 5,426 GWh import from NTDC system (including supply from 150 MW dedicated WPPs), and 535 GWh from other power plants connected with KE system.
During this period, KE generated almost 56% of the total electricity consumed in its area while rest of 44% was purchased from external sources. In comparison to FY 2019-20, during FY 2018-19, KE had generated almost 58% of the total electricity consumed in its area while remaining 42% was purchased from external sources.
KE is a privatized vertically integrated utility possessing three separate licences of Generation, Transmission and Distribution businesses. The licence issued to KE allows it to generate, transmit and distribute electricity to its consumers within its service area.
KE is operating under the licence issued by Nepra to carry out electricity transmission business within its service area. KE owns, operates and maintains transmission network of 220 kV and 132 kV.
The details of existing transmission network of KE at 220 kV and 132 kV level are as follows: (i) 365 km of 220 kV Transmission Lines; (ii) 11Grid Stations of 220 KV with transformation capacity of 4,580 MVA; (iii) 801 km of 132 kV Transmission Lines; and (iv) 68 Grid Stations of 132 KV having transformation capacity of 6,951 MVA. During FY 2019-20, 1 grid station has been added at 220 kV level while 2 grid stations have been added at 132 kV level in KE system.
KE has 11 grid stations of 220/132 kV level with 13 Nos. auto transformers of 4,580 MVA transformation capacity, 68 grid stations of 132/11 kV level with 167 Nos. power transformers of 6,951 MVA transformation capacity.
Operational record of 220/132 kV grid stations provided by KE shows no overloading during the reported period of FY 2019-20 whereas, 40 out of 167 Nos. KE's power transformers at 132/11 kV level were reported over-loaded during FY 2018-19.
KE develops, manages, maintains and operates distribution network within its service area. The distribution assets of KE include: (i) 1,890 feeders of 11 kV, 10,204 km long, (ii) 28,842 Distribution Transformers having transformation capacity of 7,915 MVA, and (iii) 18,367 km of LT Lines.
According to the report, there has been a considerable increase in over-loaded distribution transformers which increased from 808 in FY 2018-19 to 2,250 in FY 2019-20. KE has been granted a Multi-Year Tariff (MYT) for a control period of 7 years from FY 2016-17 to FY 2022-23.
Under its MYT determination, KE has been given a target of 17.76% T&D losses for the fourth year of its MYT i.e. 2019-20. However, for the FY 2019-20, the reported T&D losses of KE (excluding auxiliary consumption) were 19.73%. The overall recovery ratio of 92.14% has decreased over the last year's ratio of 92.62%.
