Overview of Tuscarora Gas Transmission Company(1)
Tuscarora is a Nevada general partnership that was formed in 1993. Its general partners are TC Tuscarora Intermediate Limited Partnership, a direct subsidiary of TC PipeLines, which owns or controls a 99 per cent general partner interest, and TCPL Tuscarora Ltd., an indirect wholly owned subsidiary of TransCanada, which holds a one per cent general partner interest.
Tuscarora owns a 240-mile, 20-inch diameter, U.S. interstate pipeline system with a subscribed capacity of approximately 180 MMcf/d that originates at an interconnection point with existing facilities of TransCanada’s GTN System near Malin, Oregon and runs southeast through northeastern California and northwestern Nevada. The Tuscarora pipeline system terminates near Wadsworth, Nevada.
The Tuscarora pipeline system was constructed in 1995 and was placed into service in December 1995. In January 2001, Tuscarora completed construction of the Hungry Valley lateral, a 14-mile, 16-inch pipeline extension that serves as Tuscarora’s second connection into Reno, Nevada. On December 1, 2002, Tuscarora completed and placed into service an expansion of its pipeline system. This expansion consisted of two compressor stations and an 11-mile pipeline extension from a point near the previous terminus of the Tuscarora pipeline system near Reno, Nevada to Wadsworth, Nevada. The expansion increased Tuscarora’s contracted capacity from 127 MMcf/d to approximately 180 MMcf/d. The new capacity was contracted under long-term firm transportation contracts ranging from ten to fifteen years from the in-service date. Tuscarora completed construction of the Barrick Lateral, a 0.5 mile lateral that provides transportation service to a new electric generation customer located near Tracy, Nevada. The construction of the lateral was completed and commissioned for service to Barrick Goldstrike on August 1, 2005. TC PipeLines' general partner, TransCanada Corporation, is the operator of Tuscarora.
Tuscarora is regulated by the Federal Energy Regulatory Commission and is subject to the FERC’s rules, regulation and accounting procedures. Tuscarora derives most of its revenue from providing firm transportation service. Revenues are received from customers based on their contracted volume, regardless of the actual volume of gas transported.
