Lakehead System

We celebrated the 60th anniversary of our Lakehead System in 2009. The first pipeline in the Lakehead System was constructed in 1949, and as of 2010, the U.S. right-ofway will have been expanded to include up to six separate and parallel crude oil and liquid petroleum pipelines. Not only is the Lakehead System a common carrier pipeline that serves as the primary transporter of crude oil and liquid petroleum to the United States from western Canada, but it also supplies the major refining markets in the U.S. Great Lakes and upper Midwest as well as in Ontario, Canada. When combined with the Enbridge Inc. mainline system in Canada, it is the longest liquid petroleum pipeline system in the world. In addition, Enbridge Inc.'s newly expanded Spearhead Pipeline connects with the Lakehead System near Chicago and offers crude oil shippers increased access to the Mid-Continent and Gulf Coast markets through the Cushing, Okla., Hub.

In 2009, average system deliveries on the Lakehead System increased by 1.9 percent, from the same period in 2008 and contributed an additional $9.5 million to operating revenue. Deliveries on the Lakehead System in 2009 averaged 1.65 million Bpd compared with 1.62 million Bpd in 2008. The increase is attributed to increases in crude oil supplies from the continued development of the Alberta oil sands.

Canada continues to be the largest source of U.S. crude oil imports by supplying about 1.2 million Bpd of the U.S. crude oil imports. Approximately 68 percent of western Canadian crude oil exports to the United States in 2009 were shipped via the Lakehead System. Of the total Lakehead System receipts, some 5 percent are sourced from domestic production, including increasing deliveries from our North Dakota System.

Crude oil price volatility in 2008 and 2009 caused some producers to cancel or defer projects. This is likely to slow the demand for additional capacity on our Lakehead mainline system in the short-term, but the Canadian Association of Petroleum Producers (CAPP) is forecasting future production from the Alberta oil sands to grow steadily during the next 10 years with an additional 1.4 million Bpd of incremental supply available by 2019.
