Iroquois Gas Transmission System, L.P., headquartered in Shelton, CT, is a partnership of affiliates of four U.S. and Canadian energy companies, and is the owner of a 416-mile interstate natural gas pipeline system extending from the U.S.-Canadian border at Waddington, NY, through New York State and western Connecticut to its terminus in Commack, NY, and from Huntington, Long Island to New York City in the Bronx. Iroquois' wholly owned subsidiary, the Iroquois Pipeline Operating Company, is the agent for and operator of the pipeline.
Iroquois received a Certificate of Public Convenience and Necessity in November of 1990 and construction of the original 375-mile pipeline began the following Spring. Iroquois began full operations on January 25, 1992, creating an important pipeline link between the North American markets and western Canadian natural gas supplies as well as supplies from the Gulf Coast.
Since 1992, Iroquois has expanded its transportation system to meet the growing energy needs of its customers in the Northeast, while minimizing the impacts on local communities. This expansion of facilities has allowed Iroquois to more than double the amount of natural gas it transports daily on its system to 1.5 billion cubic feet per day. Iroquois continues to evaluate reasonable expansions on its system in order to provide safe, clean and environmentally conscious energy projects to support the continued economic growth of New York and New England.
