Portland Natural Gas Transmission System

Portland Natural Gas Transmission System (PNGTS) is a 295-mile interstate natural gas pipeline system that originates at the terminus of TransCanada’s TQM pipeline at the Canadian border, shares facilities with the Maritimes and Northeast Pipeline from Westbrook, ME to Dracut, MA where it ultimately connects with the Tennessee Gas Pipeline System. It began serving New England’s growing energy needs in March 1999. PNGTS has a design capacity of 168 million cubic feet per day (MMcf/d) at the Canadian border which increases to 210 MMcf/d from Westbrook, ME to Dracut, MA. Greater than 60 percent of the capacity is under contracts that expire in early 2019 with the remainder of the volume transported under short-term firm and interruptible contracts. PNGTS is operated by a subsidiary of TC Energy Corporation. TC PipeLines, LP owns 50 percent of PNGTS, TransCanada PipeLines owns 12 percent of PNGTS.
