LAHORE: Sui Northern Gas Pipelines Limited’s board of directors on Friday allowed a waiver of the minimum 66 per cent take-or-pay clause for three government-owned liquefied natural gas (LNG) power plants in Punjab in a bid to reduce the burden of capacity payments and increase the interest of both local and foreign investors in the government’s plan of privatising these projects. The board also approved a proposal in principle for setting up another LNG terminal by a private firm at Karachi port.
