ISLAMABAD - The Supreme Court has summoned Attorney General for Pakistan today (Wednesday) over a petition filed by Independent Power Producers (IPPs) against the federal government for not paying their dues.The IPPs counsel informed the court that if the government would not pay their dues the country could face loadshedding for another four years.A four-member bench of the apex court, headed by Justice Tassaduq Hussain Jillani, heard the petition filed by eight IPPs against the government, which has failed to pay dues worth Rs61.401 billion to the IPPs. As a result of non-payment of dues, during the last couple of months, the power crisis has worsened in the country. This amount includes the capacity payment of Rs19.379 billion, energy payment of Rs37.846b, and other payments of Rs4.176 billion.The petitioners including Liberty Tech, Orient Power, Atlas Power, Nishat Power, Nishat Chunnian, Saif Power, Halmore Power and Sapphire Electric, seek payment of outstanding dues of Rs11.131 billion, Rs4.121 billion, Rs10.478b, Rs9.661b, Rs10.899b, Rs5.722b, Rs2.415b and Rs6.974 billion respectively.During the hearing, Fakhruddin G Ibrahim, counsel for the IPPs informed the court that the government had not paid dues worth Rs61.401b to the IPPs in the last couple of months. He said if loadshedding would worsen further what the common man would do.The learned counsel said the government was reluctant for arbitration in the matter for it thought that its case was weak. Later on, the court summoned the AGP and adjourned the hearing for today (Wednesday).It is to be noted that these eight companies, which had earlier invoked the sovereign guarantees, had filed the petitions to initiate legal action domestically, instead of approaching the international arbitrators.The federal government through the ministries of water and power and finance, National Transmission and Despatch Company (NTDC), Private Power and Infrastructure Board (PPIB), National Electric Power Regulatory Authority (Nepra), Water and Power Development Authority (Wapda), Pakistan Electric Power Company (Pepco), Central Power Purchasing Agency (CPPA), the State Bank of Pakistan (SBP) and Independent Power Producers Advisory Council are respondents.
