The company is the largest transporter of crude oil in Canada with 3 million barrels per day of oil and liquids. The Enbridge Pipeline System is the world's longest crude oil and liquids pipeline system, with 27,564 km (17,127 mi) of active crude pipeline in both Canada and the United States. This pipeline network delivers 3 million barrels of oil per day.
Enbridge delivered more than 3.77 billion barrels of crude oil in 2020, and more than 29.5 billion barrels over the past decade, from 2011 through 2020 inclusive.
Enbridge has several new capacities and expansion projects, including the expansion of the Alberta Clipper, replacing of Line 6B, reversal of Line 9 and others. Its Light Oil Market Access initiative is a project to deliver light crude oil from North Dakota and Western Canada to refineries in Ontario, Quebec, and the U.S. Midwest. Eastern Access, including a reversal of Line 9, is a project to deliver oil to Western Canada and Bakken to refineries in Eastern Canada and the midwest and eastern U.S. Western Gulf Coast Access, including reversal and expansion of the Seaway Pipeline and the Flanagan South Pipeline, is a plan to connect Canadian heavy oil supply to refineries along the Gulf Coast of the United States.
Enbridge's oil pipelines cross North America, with 13,833 km (8,672 mi) of active pipe in the United States and 13,681 km (8500 mi) of active pipe in Canada. The list below outlines eight of those lines.

Natural gas pipelines
Enbridge's pipelines transport 20% of the natural gas consumed in the United States. It owns and operates Canada's largest natural gas distribution network, providing distribution services in Ontario and Quebec. Union Gas in Ontario now fully operates under Enbridge Gas Inc. In Quebec, Enbridge has interest ownership in Gazifère.
Enbridge builds, owns and operates a network of natural gas transmission pipelines across North America, connecting the continent's natural gas supply to major markets in Canada, the United States, Mexico, and further abroad.
Enbridge's natural gas network currently covers 38,375 km (23,850 mi) across five Canadian provinces, 30 U.S. states, and offshore in the Gulf of Mexico, transporting roughly 16.2 Bcf (billions of cubic feet per day) of natural gas.
Canadian gas transmission: major assets
B.C. Pipeline (2.9 Bcf/d): this pipeline system runs from Fort Nelson in northeastern British Columbia to the U.S. border at Huntington-Sumas stretching 2,858 km (1,776 mi). It transports 60 percent of all natural gas produced in B.C., and provides natural gas service to the province as well as US states including Oregon, Idaho, and Washington.
Alliance Pipeline (1.6bcf/d): running 3,848 km (2,391 mi) from northern British Columbia across the U.S.-Canada border to Aux Sable gas processing plant in Channahon, Illinois. Enbridge owns 50 percent of the Alliance Pipeline and 42% of the Aux Sable processing facility.
U.S. gas transmission: major assets
Algonquin Gas Transmission (3.12 Bcf/d): this pipeline is 1,129 miles long, and transports natural gas to markets in New York, New Jersey, and New England.
East Tennessee (1.86 Bcf/d): a natural gas pipeline 1,526 miles long, extending from Tennessee to the Southeast and Mid-Atlantic states, ending in Virginia.
Maritimes & Northeast Pipeline: this pipeline was constructed to bring natural gas produced in Atlantic Canada through to other Canadian provinces (Nova Scotia and New Brunswick), and into U.S. states (Maine, New Hampshire, and Massachusetts).
NEXUS Gas Transmission: measuring 257 miles long, this pipeline supplies natural gas markets in the U.S. Midwest and the Dawn Hub in Ontario. This is a 50/50 joint partnership between Enbridge and DTE Energy.
Sabal Trail: carries natural gas via a 287-mile pipeline to the U.S. Southeast. This is a joint partnership between Enbridge, NextEra Energy and Duke Energy.
Southeast Supply Header (SESH) (1.09 Bcf/d): a natural gas pipeline 287 miles in length, connecting gas supply in Texas and Louisiana to other natural gas markets in the Southeast US.
Texas Eastern (12.12 Bcf/d): delivers natural gas from Texas and the Gulf Coast through 8,532 miles of pipeline to markets in the Northeastern UW including New York, Boston, and Pittsburgh.
Valley Crossing Pipeline (2.6 Bcf/d): placed into service in November 2018, this pipeline moves Texas sourced natural gas to a Mexico State-owned power utility, the Comision Federal de Electricidad (CFE).
Vector Pipeline: this pipeline acts as a connector for other pipelines including the Alliance pipeline and NEXUS Gas Transmission to the Union Gas Dawn Hub.
DCP Midstream
DCP Midstream is a joint venture between Enbridge and Phillips 66. Phillips 66 is one of the largest petroleum services companies in the US, owning and operating 39 natural gas plants and 51,000 miles of gathering pipe. Headquartered in Denver, Colorado, DCP operates a portfolio of natural gas gathering, logistics, marketing and processing services across nine states.
Renewable energy generation
Enbridge made its first investment into renewable energy in 2002 with the purchase of a wind farm. To date Enbridge has invested in 23 wind farms, 7 solar energy projects, 5 waste heat recovery facilities, 1 geothermal project, 1 power transmission project and 1 hydroelectric facility.
Enbridge has a growing interest in European offshore wind energy, and its renewable assets are part of the company's plan to achieve net-zero emissions by 2050.
Power transmission
In February 2020, Enbridge sold its shares of Montana-Alberta Tie-Line (MATL) to Berkshire Hathaway Energy. The MATL project is a 300-megawatt (MW), 230-kilovolt (kV) electrical transmission line allowing movement of power between Alberta and Montana. The MATL project, which was placed in service the fall of 2013, supports ongoing development of a rich wind-powered generation resource and allows electrical energy to flow in both directions. The transmission line is 210 miles (345 km) long and runs between the Lethbridge, Alberta area and the Great Falls, Montana area. Roughly one-third of the line is in Canada and two-thirds in the U.S.
Natural gas utility
Enbridge Gas Inc. was formed on January 1, 2019, with the combination of Enbridge Gas Distribution and Union Gas. Its network consists of 5,471 km of gas transmission lines, 66,787 km of gas distribution service lines, and 78,214 km of gas distribution main lines.
They deliver to over 15 million people in Ontario and Quebec through 3.8 million residential, commercial, industrial, and institutional meter connections and distribute roughly 2.3 bcf/d of natural gas. Additionally, in southwestern Ontario they have the largest integrated underground storage facility in Canada, and one of North America's top natural gas trading hubs.
Enbridge's natural gas distribution also includes interest ownership in two additional natural gas distributors. This includes Gazfiére, serving people in Outaouais region of Quebec, and Ènergir LP, a company that operates gas transmission, gas distribution, and power distribution throughout Quebec and Vermont.
In September 2023, Enbridge agreed to acquire three natural gas utility companies from Dominion Energy for $14 billion. The companies include the East Ohio Gas Company, Questar Gas Company, and the Public Service Company of North Carolina. These companies serve 3 million customers in the states of Ohio, Utah, Wyoming, Idaho, and North Carolina. Upon completion of the acquisition, Enbridge Gas Inc. will become the largest natural gas utility in North America supplying 9 bcf/d to 7 million customers.
Technology and innovation
Enbridge has two Technology and Innovation labs. In January 2019, the first lab opened in Calgary, Alberta. In April 2019, the second lab opened in Houston, Texas. The labs use industrial predictive algorithms, machine learning, and sentiment analysis to find efficiencies within the company and help improve safety and reliability of their pipeline infrastructure.
The labs have developed ways to get sensor data from pipelines, helping to improve flows of natural gas and crude oil terminals. Additionally, the labs have helped enhance pipeline leak detection, and ensure better maintenance schedules. For renewable energy projects, the labs have developed different ways to reposition wind turbine blades to help maximize wind power generation.
