The U.S. $13 billion Keystone pipeline system will play an important role in linking a secure and growing supply of Canadian crude oil with the largest refining markets in the United States, significantly improving North American security supply.
In June 2010 TransCanada commenced commercial operation of the first phase of the Keystone Pipeline System. Keystone's first phase was highlighted by the conversion of natural gas pipeline to crude oil pipeline and construction of an innovative bullet line that brings the crude oil non-stop from Canada to market hubs in the U.S. Midwest.
Keystone Cushing (Phase II), an extension of the Keystone Pipeline from Steele City, Nebraska to Cushing, Oklahoma went into service in February 2011. The 36-inch pipeline connects to storage and distribution facilities at Cushing, a major crude oil marketing/refining and pipeline hub.
The proposed Keystone Gulf Coast Expansion Project is an approximate 2,673-kilometre (1,661-mile), 36-inch crude oil pipeline that would begin at Hardisty, Alberta and extend southeast through Saskatchewan, Montana, South Dakota and Nebraska. It would incorporate a portion of the Keystone Pipeline (Phase II) through Nebraska and Kansas to serve markets at Cushing, Oklahoma before continuing through Oklahoma to a delivery point near existing terminals in Nederland, Texas to serve the Port Arthur, Texas marketplace.
