Iroquois Gas Transmission System

Natural Gas Icon

Overview 

The Iroquois Gas Transmission System is a limited partnership of four U.S. and Canadian energy companies or limited partnerships. The system includes a 416 mile (669 km) interstate natural gas pipeline that extends from the Canadian border at Waddington, New York, onward through New York State and western Connecticut, finally reaching its end point in the Bronx, New York.

The system began operations in 1992 and to this day fulfills its early promise of delivering a supply of safe, reliable natural gas to families and businesses in the many towns, cities and regions it passes through.

TransCanada effectively owns 13.7 percent of the Iroquois pipeline, through a 0.7 percent direct ownership and a 26.4 percent interest in TC PipeLines, LP.
