The 188-mile (303-km) Portland Natural Gas Transmission System (PNGTS) spans New England from the Canadian border to pipeline connections in New Hampshire, Maine and Massachusetts. The system began operations in 1999 and is strategically located between three major pipeline networks originating in Canada and the Southern U.S.
TC Energy owns 61.7 percent of PNGTS. The remaining 38.3% is owned by Northern New England Investment Company. The system includes 107 miles of facilities jointly owned by PNGTS and Maritimes & Northeast Pipeline. PNGTS owns 32 percent of those facilities.
