A new energy crisis is in the offing as PSO suspended the oil supply to KESC, while other power companies would meet the same plight after June 21. Sources said that the power sector is a defaulter of above Rs1 trillion of PSO while the circular debt of PSO is about Rs1.37 billion. PSO is to give Rs82billion to oil refineries and it needed Rs 36 billion for letter of credit. Thus, PSO would suspend the oil supply to KESC today as the latter has not paid the installments to the former.
