[DAWN] Water and Power Minister Khawaja Asif said here on Monday that subsidised oil supplied to power plants was being sold in the open market and alleged that a 'powerful oil lobby' was obstructing development of alternative fuels.Winding up a debate in the Senate on a Nepra report which pointed out deficiencies in the power sector, the minister said the subsidised oil was given to power plants on the basis of certain efficiencies, but they were selling surplus oil in the market to make money. There should be an audit to determine the actual consumption of oil, but nobody was contesting the stays obtained against such an audit, he regretted.
