TC PipeLines, LP Reports 2008 Third Quarter Results

CALGARY, Alberta – October 31, 2008 – (Nasdaq: TCLP) – TC PipeLines, LP (the Partnership or PipeLP) today reported third quarter 2008 net income of $28.3 million or $0.72 per common unit (all amounts in U.S. dollars), an increase of $3.7 million or 15 per cent compared to $24.6 million or $0.64 per common unit for the same period last year.

Partnership cash flows (please see the Financial Highlights table for more detail) increased $13.5 million, or 48 per cent, to $41.6 million for third quarter of 2008, compared to $28.1 million for the same period last year. This increase was primarily due to higher cash distributions received from Great Lakes Gas Transmission Limited Partnership (Great Lakes or GLGT) and Northern Border Pipeline Company (Northern Border or NBPC), increased cash flows provided by Tuscarora Gas Transmission Company’s (Tuscarora or TGTC) operating activities and lower costs at the Partnership level. The total cash distributions received represent a $9.7 million increase compared to the same quarter last year primarily due to an $8.2 million special distribution received from Northern Border upon the sale of its wholly-owned subsidiary, Bison Pipeline LLC (Bison).

Cash distributions paid by the Partnership were $27.8 million or $0.705 per common unit in third quarter 2008, an increase of $2.7 million compared to $25.1 million or $0.655 per common unit for the same period last year.

“Our current free cash flow and minimal near term capital commitments, combined with our strong balance sheet and financial liquidity, place the Partnership in a solid position to weather these unstable financial markets and to take advantage of opportunities, should they arise. The stability in our financial position also underpinned the Partnership’s recent quarterly distribution announcement of $0.705 per unit,” said Russ Girling, chairman and chief executive officer of TC PipeLines GP, Inc.

“Our focus on growing in a sustained and disciplined manner remains unchanged,” continued Girling. “Northern Border’s sale of Bison in the third quarter includes a commitment by our sponsor to continue to advance the Bison Project which would diversify the natural gas supply options for Northern Border and strengthen its contract portfolio.”

Recent Developments

Bison Pipeline Project (Bison Project) – On September 3, 2008 Northern Border announced the sale of Bison to TransCanada for a total purchase price of $20 million. The assets of Bison included executed precedent agreements subject to certain shipper contingencies, as well as regulatory, environmental and engineering activities completed on the Bison Project. Shippers on the Bison Project have executed contracts for capacity on the Northern Border system from Port of Morgan, Montana to Ventura, Iowa on the Northern Border system, subject to the in-service date of the Bison Project. The sale of Bison positions the Bison Project to potentially combine with TransCanada’s proposed Pathfinder Project that would interconnect with the Northern Border system. If the Bison Project or the Pathfinder Project is successful, it would diversify natural gas supply and potentially increase demand for transportation services on the Northern Border system.

(1) The Partnership owns a 100 per cent general partner interest in Tuscarora following the acquisition of an additional two per cent interest on December 31, 2007.

(2) The Partnership acquired a 46.45 per cent partner interest in Great Lakes on February 22, 2007.

(3) The Partnership owns a 50 per cent general partner interest in Northern Border. Equity income from Northern Border includes amortization of a $10.0 million transaction fee paid to the operator of Northern Border at the time of the additional 20 per cent acquisition in April 2006.

Net income increased $3.7 million, or 15 per cent, to $28.3 million in third quarter of 2008, compared to $24.6 million in third quarter of 2007. This increase was primarily due to higher equity income from Northern Border, increased Tuscarora transmission revenues and lower financial charges, net and other, partially offset by decreased equity income from Great Lakes.

3

Equity income from Great Lakes was $12.0 million in third quarter of 2008, a decrease of $2.2 million or 15 per cent, compared to $14.2 million for the same period last year. The decrease in equity income was primarily due to increased operating expenses and Michigan business tax (a partnership level tax that was instituted in 2008), partially offset by increased transmission revenues. At Great Lakes’ level, operating expenses increased $4.5 million for the three months ended September 30, 2008 compared to the same period last year primarily due to higher taxes other than income, costs related to system integration expenditures and increased pipeline maintenance costs. Michigan business tax of $1.2 million was recorded for the three months ended September 30, 2008. Great Lakes’ transmission revenues increased $1.1 million for the three months ended September 30, 2008 compared to the same period last year due primarily to higher short-term revenues from increased sales of daily transport capacity.

Equity income from Northern Border was $19.9 million in third quarter of 2008, an increase of $3.7 million or 23 per cent, compared to $16.2 million in the same period last year. This is primarily due to a $16.1 million gain on sale of Bison, partially offset by lower transmission revenues. At Northern Border’s level, transmission revenues decreased $11.9 million, or 15 per cent, for the three months ended September 30, 2008 compared to the same period last year due primarily to a decrease in system utilization mainly related to natural gas supply from the Rockies Basin into the Mid-Continent market from the in-service of the western segment of the Rockies Express Pipeline.

Tuscarora’s net income was $3.9 million in third quarter of 2008, an increase of $1.0 million or 34 per cent, compared to $2.9 million in the same period last year. The increase in net income is primarily due to increased transmission revenues resulting from a new firm transportation service contract which supportedthe Likely compressor station expansion that went into service on April 1, 2008.

Financial charges, net and other were $7.7 million in third quarter of 2008, a decrease of $1.0 million or 11 per cent, compared to $8.7 million in the same period last year. This decrease relates primarily to lower interest rates and lower average debt outstanding, partially offset by losses on interest rate derivatives over the same period in 2007.

Partnership Cash Flows

The Partnership uses the non-GAAP financial measures ‘Partnership cash flows’ and ‘Partnership cash flows allocated to common units’ as financial performance measures.As the Partnership’s financial performance underpins the availability of cash flows to fund the cash distributions that the Partnership pays to its unitholders, the Partnership believes these are key measures of the available cash flows to its unitholders.The following Partnership cash flows information is presented to enhance investors’ understanding of the way that management analyzes the Partnership’s financial performance.Partnership cash flows and Partnership cash flows allocated to common units are provided as a supplement to GAAP financial results and are not meant to be considered in isolation or as substitutes for financial results prepared in accordance with GAAP.

(1) Partnership cash flows allocated to general partner represents the cash distributions paid to the general partner with respect to its two per cent interest plus an amount equal to incentive distributions.
(2) Cash distributions declared per common unit and cash distributions paid per common unit are computed by dividing cash distributions, after the deduction of the general partner's allocation, by the number of common units outstanding. The general partner's allocation is computed based upon the general partner's two per cent interest plus an amount equal to incentive distributions.

Partnership cash flows increased $13.5 million, or 48 per cent, to $41.6 million for third quarter of 2008, compared to $28.1 million for the same period last year. This increase was primarily due to higher cash distributions received from Great Lakes and Northern Border, increased cash flows provided by Tuscarora’s operating activities and lower costs at the Partnership level. In third quarter 2008, the Partnership received total cash distributions of $41.9 million, of which $19.3 million was received from Great Lakes and $22.6 million was received from Northern Border. The total cash distributions received represent a $9.7 million increase compared to the same quarter last year primarily due to an $8.2 million special distribution received from Northern Border as a result of the sale of Bison. Cash flows provided by Tuscarora’s operating activities increased by $2.6 million for the quarter ended September 30, 2008 compared with the same period last year primarily due to higher transmission revenues resulting from the Likely compressor station expansion project that went into service on April 1, 2008. Also contributing to the increase in Partnership cash flows is a $1.2 million decrease in net financial charges at the Partnership level.

The Partnership paid distributions of $27.8 million in third quarter of 2008, an increase of $2.7 million, or 11 per cent, compared to $25.1 million for the same period in the prior year and repaid a net $3.0 million of the outstanding debt balance.

Liquidity and Capital Resources

As of October 31, 2008, the Partnership had no outstanding borrowings under the $250.0 million revolving portion of its revolving credit and term loan agreement and was in compliance with the covenants of the agreement. The interest rate incurred on the credit facility (includes both outstanding term loans and revolving borrowings) averaged 5.23 per cent for the three months ended September 30, 2008 after accounting for hedging activity.

The Partnership views its core banking group as high quality and has a well-established relationship with these institutions. The Partnership has an existing $250.0 million debt and equity shelf expiring December 1, 2008 which it expects to renew in fourth quarter 2008. This will supplement the $250.0 million of capacity available under the Partnership’s existing revolving credit and term loan facility which expires on December 12, 2011.
