By Peter Uzoho Excessive administrative and other sundry charges by the Department of Petroleum Resources (DPR), the Petroleum Products Pricing Regulatory Authority (PPPRA), among others, have caused an astronomical rise in the price of Liquefied Petroleum Gas (LPG) commonly known cooking gas, THISDAY’s investigation has revealed. Also, insufficient supply of LPG to local marketers by the Nigeria Liquefied Natural Gas (NLNG) Limited, which is the major supplier of the product in-country, has also contributed to the scarcity of the product and the resultant increase in price lately. The numerous charges by the regulators have forced the marketers of the product to hike the price at their stations, resulting in consumers having to pay more for cooking gas, which the federal government is projecting as the preferable cooking fuel.
