Background

Alliance Pipeline transports natural gas from northeastern British Columbia and northwestern Alberta, running underground through Saskatchewan, North Dakota, Minnesota, Iowa, and terminating in Illinois. The pipeline delivers more than 1.6 billion cubic feet per day of liquids-rich natural gas to the Chicago market.

The Alliance Pipeline system consists of a 3,848 km (2,391 mi) integrated Canadian and U.S. natural gas transmission pipeline system, delivering natural gas from the Western Canadian Sedimentary Basin and the Williston Basin to the Chicago market hub. The system has been in commercial service since December 2000 and delivers, on average, about 1.6 billion standard cubic feet (or 45.3 million standard cubic metres) of natural gas per day.

Canada Portion

338.37 km (210.25 mi) of 1067 mm (42-inch) and 1,221.73 km (759.15 mi) of 914 mm (36-inch) diameter steel pipe 52 receipt points connecting with lateral pipelines totaling about 731.36 km (454.45 mi), ranging in length from about 0.3 to 142 km (0.19 to 88.23 mi) and in diameter from 114 to 610 mm (4.5 to 24.0 in) 7 mainline compressor stations of about 23 to 34 MW (31,000 to 46,000 hp) each, spaced about 193 km (120 mi) apart 7 compressor stations on the lateral system that range from 0.4 - 15 MW (500 - 20,000 hp) Mainline block valves spaced about every 32 km (20 mi) apart Maximum Canadian operating pressure: 12,017 kPa (1,743 psig) Contract capacity: 130.5 million cubic meter/d (4.6 Bcf/d)

United States Portion

886.41 miles (1,426.54 km) of 36-inch (910 mm) diameter steel pipe 2 receipt points (Bantry) connecting the Prairie Rose Pipeline and Tioga Lateral connecting at Sherwood, ND 7 compressor stations of about 31,000 hp (23 MW) each, spaced about 120 miles (190 km) apart 11 delivery stations, including Aux Sable, Hankinson and Lyle Mainline block valves spaced about every 20 miles (32 km) apart Maximum US operating pressure: 13,341 kPa (1,935 psig) Contract capacity: 42.8 million cubic meter/d (1.513 Bcf/d)

Ownership

Alliance Pipeline Limited Partnership ("Alliance Canada") owns the Canadian portion of the Alliance Pipeline system. Alliance Pipeline L.P. ("Alliance U.S.A.") owns the U.S. portion of the Alliance Pipeline system. Both Alliance Canada and Alliance U.S.A. are owned 50 percent each by affiliates of Enbridge Income Fund Holdings Inc. (TSX:ENF) and Pembina Pipeline Corporation. (TSX:PPL).

The expansion in Three Rivers, Illinois will provide natural gas to the planned 1,300MW combined-cycle CPV Three Rivers energy center.

Capacity Expansion

The proposed expansion project included the addition of compression and other facilities to an existing pipeline system to add 400 MMcf/d. Pending regulatory approval, this would amount to an increase in capacity by ~25% through the addition of compression and other facilities to its system. Completion was expected by the end of 2021.

A binding open season for the expansion was announced in 2018, and by June 2018 the project had failed to reach sufficient financing.
