ISLAMABAD - Pakistan is likely to face another jolt in shape of oil and power crisis in near future as after facing cold shoulder response from the power sector on account of payment, the receivables of the cash-strapped Pakistan State Oil (PSO) have swelled to Rs 156 billion. However, PSO is persistently struggling to arrange petroleum products to continue oil supply, sources said on Wednesday. The sources informed that despite frequent requests to power sector for clearing dues, PSO had received Rs 2.8 billion from Wapda only. The PSO is providing furnace oil to power sector worth Rs 1.5 billion per day to power sector. The sources maintained that country was depending on import of furnace oil and PSO will be facing default of Letter of Credits (L/Cs) for its import. However, after the governments decision to dissolve Pakistan Electric Power Company (Pepco), the whole mechanism of payment has been disturbed and no one is responding to PSO on the issue of payment, the sources added. PSO has deferred tenders for import of oil products many times due to non-payment of dues by power sector, the sources said adding that the same situation was being revised at present. It is important to note that as on December 22, 2010, PSO receivables against different clients stood as; WAPDA Rs 52.24 billion, Hubco Rs 62.3 billion, Kapco Rs 27.2 billion, PIA Rs 506 million, OGDC Rs 475 million, KESC Rs 1.99 billion, financial charges from PIA Rs 960 million, price differential claims (PDC) on High Speed Diesel (HSD) Rs 1.38 billion and PDC on imported PMG Rs 4.8 billion. However, PSO is to pay Rs 124.25 billion dues to local as well as international fuel suppliers which are follows as; Rs 37.12 billion to Parco, Rs 11.5 billion to PRL, Rs 9.3 billion to NRL, Rs 29.23 billion to ARL, Rs 4.69 billion to Bosicor and Rs 31.6 billion on L/Cs payments to international fuel suppliers. The power sector requires to manage fuel for five days need but it is currently managing for two days requirement due to the lack of storage, the sources said adding that oil refineries were also operating at 60 percent production capacity due to the circular debt issue.
