The Northern Border Pipeline Company owns and operates a large diameter, natural gas pipeline system that joins the natural gas fields of the Western Canadian Sedimentary Basin and the U.S. Williston Basin with markets throughout the Midwestern U.S.
The first phase of Northern Border, from Monchy, Saskatchewan to Ventura, Iowa began operation in 1982, transporting approximately 975 million cubic feet per day (MMcf/d) of natural gas. In fall 1991, Northern Border placed its first new facility, compressor station number 10, on line and increased system capacity by 150 MMcf/d. In 1992, system capacity increased again, this time to 1,675 MMcf/d, by adding four new compressor stations and 147 miles of 30-inch diameter pipeline.
In 1997, Northern Border received a certificate of public convenience and necessity from the Federal Energy Regulatory Commission to begin construction of THE Chicago Project. THE Chicago Project involved the construction of 390 miles of new 36- and 30-inch diameter pipeline, eight new 35,000 horsepower gas turbine compressor stations, upgrading 5 existing gas turbine compressor stations to 35,000 horsepower and adding one 6,500 horsepower electric power and one 12,000 horsepower electric power compressor station. THE Chicago Project extended the pipeline system from Harper, Iowa to Manhattan, Illinois and expanded the delivery capacity to 2.375 billion cubic feet per day (Bcf/d).
Placed in service on December 22, 1998, THE Chicago Project provides Northern Border's shippers with flexible access to natural gas markets. The extended pipeline systems interconnects with the systems of Northern Natural Gas Company; Natural Gas Pipeline Company of America; MidAmerican Energy Company; Interstate Power Company; Northern Illinois Gas Company; Midwestern Gas Transmission Company; ANR Pipeline Company and The Peoples Gas Light and Coke Company.
Throughput volumes for 1998 averaged 1737 MMcf/d, compared with 1,770 MMcf/d for 1997.
