Iroquois Gas Transmission System

The Iroquois Gas Transmission system connects from the Canadian Mainline at the Canada-U.S. border to bring natural gas to significant markets in and around New York City.
The Iroquois pipeline is part of TransCanada's network of 60,000 km (37,000 miles) of wholly owned and 7,900 km (4,900 miles) of partially owned pipelines connecting major supply basins with major markets all across North America. TransCanada is one of the continent’s largest providers of gas storage and related services with approximately 380 Bcf of storage capacity – that’s the second largest in North America. In total, TransCanada delivers approximately 20 per cent of the natural gas consumed in North America each day.

TransCanada has a 44.5 per cent ownership stake in the Iroquois Gas Transmission System.
