NATIONAL ELECTRIC POWER REGULATORY AUTHORITY (NEPRA)EXECUTIVE SUMMARYNational Electric Power Regulatory Authority (NEPRA) regulates the power sector in Pakistan andprotects the interests of consumers and companies providing electric power services. As such,apart from monitoring the performance of transmission and distribution licensees, NEPRA alsomonitors the performance of generation licensees.NEPRA framed Performance Standards Generation Rules (PSGR) back in 2009. Under PSGR, eachoperational generation licensee is required to submit a quarterly report to NEPRA on regularbasis, particularly with respect to parameters such as Reference Capacity/Net Capacity,Planned/Unplanned Outage Hours, Availability Factor, Net Capacity Factor, Net Output Factorand Energy Availability Factor. The main purpose/objective of these parameters is to ascertainwhether;i.The net capacity of power plant remained equal/higher to that approved byNEPRA in its tariff determination or otherwise.ii.The power plant availed outages in accordance with the Power PurchaseAgreement signed with CPPA-G or otherwise.iii.The CPPA-G imposed Liquidated Damages on non-performance of power plant orotherwise.iv.The power plant remained under-utilized or otherwise.Accordingly, the quarterly reports submitted by public sector GENCOs for the FY 2016-17 and2017-18 were reviewed and a comprehensive Performance Evaluation Report has beenprepared. The report mainly highlights the following key findings;i.Reduction in Net Capacity: The data submitted by GENCOs for the FY 2016-17 and2017-18 reflects that a number of units/machines of different power stations ofGENCOs have failed to ensure the Net Capacity as approved by NEPRA in theirrespective tariff determinations (upon which they are receiving capacitypayments). This resulted into a cumulative energy loss of about 479.573 MillionkWh, translating into a financial impact of Rs.4.025 Billion, as per the followingdetails;GENCOIIIIIIIVTotalEnergy Loss(Million kWh)66.270195.554204.64913.100479.573Performance Evaluation Report of Public Sector GENCOsFinancial Impact(Rs.

NATIONAL ELECTRIC POWER REGULATORY AUTHORITY (NEPRA)These units include Units 1 to 4 of TPS Jamshoro (GENCO-I), Units 3, 5, 6, 11 & 12of TPS Guddu & Unit 15 of Guddu 747 CCPP (GENCO-II), Units 1, 4 & 5 of TPSMuzaffargarh, Unit 9 of GTPS Faisalabad, Unit 2 of SPS Faisalabad & NandipurPower Plant (GENCO-III) and Units 1 & 2 of Lakhra Power Station (GENCO-IV).ii.Availing Higher Outages/Reduction in Availability Factor: The data submitted byGENCOs for the FY 2016-17 and 2017-18 indicates that a number ofunits/machines of different power stations of GENCO-I, II & III availed higheroutage hours than allowed limit as specified in their respective Power PurchaseAgreements, resulting in reduction of their Availability Factor. Had these units notavailed higher outage hours, a huge amount of energy - around 9373.003 MillionkWh could have been contributed by them to the national grid (subject to dispatchby the system operator), amounting to Rs. 64.629 Billion as per the followingdetails;GENCOIIIIIITotalEnergy Loss(Million kWh)21.9467542.4481808.6099373.003Financial Impact(Rs. Billion)0.19048.50215.93764.629These units include Unit 2 of TPS Jamshoro & Units 3 & 5 of GTPS Kotri (GENCO-I),Units 1, 2, 4, 7, 8, 9, 11 & 13 of TPS Guddu & Units 14, 15 & 16 of Guddu 747 CCPP(GENCO-II) and Units 4, 5 & 6 of TPS Muzaffargarh, Unit 1 of SPS Faisalabad &Nandipur Power Plant (GENCO-III).It is pertinent to mention that CPPA-G has imposed liquidated damages amountingto Rs. 2.093 Billion on GENCO-I, II & III, on account of availing higher outages thatallowed limit as specified in their respective Power Purchase Agreements duringthe FY 2016-17. However, the same is still in process for the FY 2017-18.iii.Longer Duration of Standy Mode: The data submitted by GENCOs for the FY 201617 and 2017-18 shows that a number of units/machines of different powerstations of GENCO-I, II & III remained on standy mode for an alarming longerduration, which resulted in the consumption of auxiliary power and a subsequentfinancial loss of around Rs. 1.031 Billion to the national exchequer.On enquiry from GENCOs in this regard, it was revealed that instructions from thesystem operator (NPCC) due to no demand and fuel constraints were the majorreasons of such longer duration of standby mode.Performance Evaluation Report of Public Sector GENCOsPage 2
NATIONAL ELECTRIC POWER REGULATORY AUTHORITY (NEPRA)iv.Net Capacity Factor: The Net Capacity Factor is the ratio of net actual generationto the product of net capacity and period hours.The data pertaining to Net Capacity Factor, as submitted by public sector GENCOsfor the FY 2016-17 and 2017-18, reveals that the Net Capacity Factor of all theGENCOs remained low (less than 68%) during the said period, owing to increasedduration of outages and underutilization of power plants. Particularly, the NetCapacity Factor of GTPS Kotri (GENCO-I), GTPS & SPS Faisalabad (GENCO-III) andLakhra PS (GENCO-IV) remained only 10%, 6%, 1% and 2% respectively during theFY 2017-18, which raises serious question marks on the performance of thesepower stations.v.Net Output Factor: The Net Output Factor is the ratio of net actual generation tothe product of net capacity and service hours. Its value should be nearly equal to100%.The data pertaining to Net Output Factor as submitted by public sector GENCOsfor the FY 2016-17 and 2017-18, depicts that the Net Output Factor of TPS Guddu& Guddu 747 (GENCO-II) and TPS Muzaffargarh & Nandipur Power Plant (GENCOIII) remained low (less than 80%) during the FY 2016-17 and 2017-18. Similarly,the Net Output Factor of TPS Jamshoro & GTPS Kotri (GENCO-I) remained only71% and 76% respectively during the FY 2017-18 and that of Lakhra Power Station(GENCO-IV) remained only 66% during the FY 2016-17, which clearly speaks of theunderutilization of these power plants during the said period.Concluding, it can be said that as a result of successive legal actions taken by NEPRA on nonperformance of GENCO-I, II & III during the calendar years 2012 to 2014 (resulting in impositionof Rs. 5 Million each on GENCO-I, II & III) and during the fiscal years 2015 and 2016 {(resulting inimposition of Rs. 2 Million fine each on GENCO-I & II (legal proceedings against GENCO-III arecurrently under process)}, the performance of abovementioned GENCOs has considerably beenimproved during the FY 2016-17 and 2017-18. However, the same is still beyond the targets asapproved by NEPRA in their respective tariff determinations with respect to reduction in netcapacity and as specified in their respective Power Purchase Agreements signed with CPPA-Gwith respect to availing higher outages.Performance Evaluation Report of Public Sector GENCOsPage 3
