In Canada, the first phase of the Keystone project involved the conversion of approximately 864 km of existing natural gas pipeline in Saskatchewan and Manitoba to crude oil pipeline service. It also included the construction of approximately 373 km of new 30 inch diameter pipeline, 16 pump stations and the Keystone Hardisty Terminal.

The US portion of the Keystone Pipeline included construction of 1,744 km of new, 30 inch diameter pipeline in North Dakota, South Dakota, Nebraska, Kansas, Missouri and Illinois. It also involved construction of 23 pump stations and delivery facilities at Wood River and Patoka, Illinois.

TransCanada has commenced construction of the second phase of Keystone, which includes a 480 km extension from Steele City, Nebraska to Cushing, Oklahoma and 11 new pump stations, which will increase the capacity of the pipeline from 435,000 bbl/d to 591,000 bbl/d.

The second phase of Keystone is expected to be in-service in the first quarter of 2011.
