Sir: Everyone is suffering from load shedding. There have also been reports in the media about angry people ransacking offices of WAPDA and power distribution companies. According to reports in newspapers, the duration of load shedding has been increased because of non-availability of gas and furnace oil. It is said that non-payment and long outstanding dues by electricity defaulters cause the non-availability of fuel. The figure of electricity defaulters is quite huge as revealed from time to time by the Pakistan Electric Power Company. It has to recover a big amount from all provinces, including AJK. Sindh has to pay over Rs 39 billion, Balochistan Rs18 billion, Punjab Rs 5 billion, Khyber Pakhtunkhwa Rs16 billion and Azad Jammu Kashmir Rs10 billion electricity dues. A rough estimate of the amount to be received by power generation companies is over Rs 350 billion. This is a lot of money. There is thus a dire need to establish a bill payment culture in every department, institution and household to overcome the problem of power shortage. RAHIMA MOIN Karachi
