News Release

TC PipeLines, LP Announces 2004 Third Quarter Results

        CALGARY, Alberta — October 26, 2004 — (Nasdaq: TCLP) — TC PipeLines, LP (the Partnership) today reported third quarter 2004 net income of $12.6 million or $0.68 per unit (all amounts in U.S. dollars) compared to $12.0 million or $0.65 per unit in third quarter 2003. For the nine months ended September 30, 2004, the Partnership reported net income of $39.9 million or $2.17 per unit compared to $35.9 million or $1.97 per unit for the same period last year.

        Cash generated in the third quarter of 2004, including $4.4 million of cash distributed from the Partnership's investments in Northern Border Pipeline Company and Tuscarora Gas Transmission Company classified as a return of capital, increased $4.1 million to $16.9 million compared to $12.8 million in 2003. For the nine months ended September 30, 2004, cash generated, including return of capital from Northern Border Pipeline and Tuscarora, amounted to $50.8 million, an increase of $13.6 million compared to $37.2 million for the same period last year. This increase is primarily due to higher cash distributions from Northern Border Pipeline compared to the prior year reflecting the impact of a change in its cash distribution policy effective January 1, 2004, as well as the negative impact to the second quarter 2003 cash distributions resulting from refunds paid by Northern Border Pipeline to its shippers for electricity costs. These amounts refunded had previously been collected through company-use gas provision.

        "We continue to be pleased with the financial results generated by our pipeline investments," said Ron Turner, president and chief executive officer of the general partner, TC PipeLines GP, Inc. "The Partnership's third quarter results reflect increased income and cash flow from both our investments in Northern Border Pipeline and Tuscarora relative to the same period last year."

        On October 19, 2004, the Partnership announced its third quarter cash distribution in the amount of $0.575 per unit.

(1)

Net Income per unit is computed by dividing net income, after deduction of the general partner's allocation, by the number or common and subordinated units outstanding. The general partner's allocation is computed based upon the general partner's 2 per cent interest plus an amount equal to incentive distributions.

(2)

Current accounting practice requires the classification of cumulative cash distributions in excess of cumulative equity earnings to be reported as a return of capital.

(3)

The Partnership's 2004 third quarter cash distribution will be paid on November 12, 2004 to unitholders of record as of October 29, 2004.

Net Income

        The Partnership reported third quarter 2004 net income of $12.6 million or $0.68 per unit, an increase of $0.6 million compared to $12.0 million or $0.65 per unit in third quarter 2003.

        Equity income from Northern Border Pipeline was $11.3 million in third quarter 2004 compared to $11.2 million in the same quarter of 2003. The increase is attributable to higher revenues and lower interest costs partially offset by a $0.6 million (TC PipeLines' share equals $0.2 million) write-off of previously capitalized costs. The increase in revenues reflects Northern Border Pipeline's ability to generate and retain more revenues from the sale of short-term capacity and additional transportation services. The reduction in interest costs is primarily due to a lower average long-term debt balance. Equity income from Tuscarora amounted to $1.8 million in third quarter 2004 compared to $1.3 million for third quarter 2003. The increase was primarily due to revenues from long-term firm transportation contracts, which commenced in November 2003, related to Tuscarora's 2002 expansion.

        The Partnership's third quarter 2004 general and administrative expenses of $0.3 million are $0.2 million lower compared to $0.5 million in the same quarter of 2003. This is primarily due to the timing of expenses incurred during the year. Financial charges of $0.2 million in third quarter 2004 as compared to less than $0.1 million in the same period last year are due to the higher average debt balances.

Cash Flow

        The Partnership reported third quarter 2004 cash generated from operations of $12.5 million compared to $12.8 million for third quarter 2003. When including the portion of the cash distribution from Northern Border Pipeline and Tuscarora reported as a return of capital, cash generated increased to $16.9 million in 2004.

        In third quarter 2004, the Partnership received a cash distribution from Northern Border Pipeline of $15.5 million, $4.2 million of which has been classified as return of capital, compared to $11.6 million in third quarter 2003, an increase of $3.9 million. This increase in the third quarter 2004 distribution is mainly due to a change in Northern Border Pipeline's cash distribution policy effective January 1, 2004. Under this new policy, cash distributions are based upon 100 per cent of distributable cash flow and calculated as earnings before interest, taxes, depreciation and amortization, less interest and maintenance capital expenditures, as reported in Northern Border Pipeline's financial statements.

        Cash distributions from Tuscarora for the third quarter 2004 were $2.0 million, $0.2 million of which has been classified as return of capital. This is an increase of $0.4 million relative to third quarter 2003. This increase was due to higher revenues from long-term firm transportation contracts, which commenced in November 2003, related to Tuscarora's 2002 expansion.

        In the first half of 2004, the Partnership borrowed an aggregate of $20 million under the revolving credit facility, which was used primarily to finance its equity contribution to Northern Border Pipeline. In the third quarter of 2004, the Partnership repaid $6 million of this amount. The balance outstanding as at September 30, 2004 is $19.5 million.

        During third quarter 2004, the Partnership paid an aggregate $10.7 million of cash distributions to unitholders and its general partner, compared to $10.1 million in third quarter 2003. This cash distribution, on a per unit basis, represents $0.575 per unit in third quarter 2004, compared to $0.55 per unit in third quarter 2003, as well as the general partner interest, including incentive distributions.
