Natural gas pipelines and processing

As the world transitions to a lower-carbon energy future, natural gas will play a vital role—as a replacement fuel for coal in electricity generation, a low-carbon source of home heating, a lower-emission fuel for heavy-duty vehicles and large transportation fleets, and a complement to the growth of renewable energy.

Enbridge is a major player in North America’s natural gas industry, with gathering, transportation, processing and storage facilities from Texas to Maine to Florida to British Columbia. We move about 20% of all natural gas consumed in the United States, serving key supply basins and demand markets.

Our natural gas operations include:

  • 34,410 miles (55,377 km) of gas pipelines;
  • 11.4 Bcf/d of processing capacity;
  • 307 MBbl/d of natural gas liquids (NGLs) production; and
  • 415 Bcf of storage.

Canadian midstream

Enbridge’s Canadian midstream operations are based in the Montney and Duvernay plays of B.C. and Alberta, which are among the most competitive natural gas and NGL plays in North America, as well as the dry gas Horn River shale in northern B.C. These operations include:

  • An ownership interest in Aux Sable Canada assets, which include its Heartland Offgas Plant near Fort Saskatchewan, AB, and interests the Septimus and Wilder Gas Plants and Septimus Pipeline near Fort St. John, BC;
  • The Pipestone and Sexsmith gathering systems near Grande Prairie, AB;
  • The Cabin Gas Plant near Fort Nelson, BC; and
  • The Tupper Main and Tupper West gas plants and associated pipelines, near Dawson Creek, BC.

Alliance Pipeline

Enbridge has an ownership interest in Alliance Pipeline, which transports liquids-rich natural gas from the Western Canadian Sedimentary Basin and the Williston Basin to the Chicago natural gas market hub. The Alliance system is ideally positioned to benefit from production growth in a number of liquids-rich natural gas shale plays, particularly the Montney and Duvernay in western Canada, as well as the Bakken in North Dakota.

U.S. gathering and processing

Through Enbridge Energy Partners, we operate a vast network of natural gas gathering and transmission lines, as well as natural gas liquids (NGL) gathering and transportation lines and natural gas processing and treating plants.

Additionally, we have a 35-percent interest in a major NGL system connecting natural gas- and NGL-producing regions to the primary NGL demand center on the U.S. Gulf Coast. These assets, which are located primarily in Texas and Oklahoma, include:
