The Tema Oil Refinery (TOR) says it has doubled supply of Liquefied Petroleum Gas to help mitigate the shortage on the market.TOR on the average supplies about 500 metric tones of LPG a day onto the market, but it has increased this to one thousand to address the short fall.The shortage has caused long queues of vehicles and cylinders at most filling stations across the country in the past weeks.According to the Refinery, repair works on a pipeline that conveys gas from the Tema Port forced the suspension of supply.It is however hopeful that the increase in supply as well as working beyond scheduled hours will address the situation.Source: Joy Business/Myjoyonline.com/Ghana
