ISLAMABAD (APP) - The apparently perturbed Oil and Gas Regulatory Authority by proposed deregulation of petroleum products prices, has claimed to have saved over billions of rupees for gas sector consumers and national exchequer since its inception. We cannot share our proposals for policy of deregulation of petroleum products, it is up to the government to decide on prices mechanism of the petroleum products, we have to accept and implement whatever comes out of the proposed policy, a senior OGRA official told APP on Tuesday. But on the OGRAs part, the official said it efficiently worked within its delegated powers and extended relief to the consumers. The OGRAs effective intervention has resulted in considerable savings to the gas sector consumers and national exchequer, which otherwise would have led to increase in gas prices, he added. Giving details, the official said the authority disallowed a total of Rs 27 billion over a period of eight years on account of line losses to be passed onto the consumers by gas utilities-SNGPL and SNGCL. Citing relevant rules, the official said the OGRA, for the first time, had undertaken a yardstick regulation by introducing the Unaccounted for Gas (UFG) benchmark, owing to which burden of excessive line losses was not being passed onto the consumers, rather the utilities themselves had to bear the cost of such inefficiencies. Besides, he said the OGRA had also introduced Human Resource (HR) benchmark in order to rationalize this major cost element, which has historically been a source of major abuse. Savings on account of HR benchmark, the source said, had also exceeded Rs 1b over a period of last four years. The official said the OGRA had also conducted an in-depth cost evaluation of each item of operating expenditure, including fixed assets in terms of rationality and prudence keeping in view the principle of need assessment and cost effectiveness. Based on OGRAs critical examination, the official claimed return on assets cost had been reduced by Rs 18.8b by end of last financial year. Replying to a question, the official dispelled the impression that the OGRA made an arbitrary decision, saying the authority examined the Revenue Requirement(RR) petitions in light of relevant rules and involved interactive process of consultation with all stake-holders through public hearings. The official said the scrutiny by OGRA involved a detailed examination of the operating revenues, cost and asset-base. Replying another question, he said the authority had designated officers for handling complaints with specific jurisdictions.
