SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the registrant has duly caused this report to be signed on its behalf by the undersigned thereunto duly authorized. TC PipeLines, LP By: TC PipeLines GP, Inc., its general partner Dated: January 30, 2003 By: /s/ Theresa Jang ---------------- Theresa Jang Controller -3- Exhibit 99.1 [TC Pipelines Logo] TC PipeLines, LP - ------------------------------------------------------------------------------ Media Inquiries: Glenn Herchak/Kurt Kadatz (403) 920-7877 Unitholder and Analyst Inquiries: Theresa Jang (403) 920-2050 Toll-free (877) 290-2772 NEWS RELEASE TC PipeLines, LP Reports 2002 Annual and Fourth Quarter Results CALGARY, Alberta - January 30, 2003 - (Nasdaq: TCLP) - TC PipeLines, LP (the Partnership) today reported net income of US$45.5 million or US$2.50 per unit for the year ended December 31, 2002, a 5% increase from 2001 net income of US$43.5 million or US$2.40 per unit. Net income for the fourth quarter of 2002 was US$8.9 million or US$0.49 per unit, a 25% decrease compared to US$11.8 million or US$0.65 per unit for the fourth quarter of 2001. The Partnership's 2002 fourth quarter net income was negatively impacted by a significant decrease in equity income from its investment in Northern Border Pipeline Company. In the fourth quarter of 2002, Northern Border Pipeline recorded a reserve of US$10.0 million (TC PipeLines' 30% share is US$3.0 million or US$0.16 per unit) to reflect the potential costs that may arise from its treatment of previously collected quantities of natural gas used in utility operations to cover electric power costs. While Northern Border Pipeline advises TC PipeLines it cannot predict the ultimate outcome of this matter, Northern Border Pipeline has concluded it prudent to establish a reserve at this time. Excluding the impact from this reserve, the Partnership's net income would have been US$48.5 million or US$2.66 per unit for the year ended December 31, 2002 and US$11.9 million or US$0.65 per unit for the fourth quarter of 2002. "Although this has an unfavorable impact on our 2002 net income, I want to assure our unitholders this event does not impact the Partnership's ability to pay the previously announced fourth quarter cash distribution of US$0.525 per unit," said Ron Turner, President and Chief Executive Officer of TC PipeLines GP, Inc., the general partner. "And while we anticipate a corresponding US$3.0 million decrease to our cash flow from Northern Border Pipeline in 2003, we believe this reserve will not impact our ability to make quarterly cash distributions at the current level to our public unitholders for the foreseeable future." The Partnership reported 2002 cash generated from operations of US$52.1 million, a 21% increase from 2001 cash generated from operations of US$42.9 million. Cash generated from operations for the fourth quarter of 2002 was US$13.4 million, a 14% increase compared to US$11.8 million for the fourth quarter of 2001. "Throughout 2002, we have continued to demonstrate our commitment to maintain the Partnership's financial strength by prudently allocating our cash between increased distributions to our unitholders, debt reduction, and capital spending related to Tuscarora's expansion," said Turner. The Partnership also announced that Tuscarora's expansion facilities, consisting of two compressor stations located along the Tuscarora mainline and an 11-mile pipeline extension to Wadsworth, Nevada, were placed into service on December 1, 2002. "We congratulate Tuscarora's project team for successfully completing this expansion on time and under budget and for safely implementing the start up of the facilities," said Turner. The expansion increases Tuscarora's capacity by approximately 55 million cubic feet per day to approximately 182 million cubic feet per day. All of the new capacity is contracted under firm transportation contracts for terms ranging from ten to fifteen years, enhancing TC PipeLines' stable and steady cash flow profile. FINANCIAL HIGHLIGHTS (millions of U.S. dollars, except per unit amounts)

THREE MONTHS TWELVE MONTHS ENDED DECEMBER 31 ENDED DECEMBER 31 (audited) - -------------------------------------------------------------------------- 2002 2001 2002 2001 ----------------- ----------------- Net Income (1) 8.9 11.8 45.5 43.5 Per unit (1) $0.49 $0.65 $2.50 $2.40 Cash Generated from Operations 13.4 11.8 52.1 42.9 Cash Distributions Declared (2) 9.6 9.1 37.8 35.7 Per unit (2) $0.525 $0.50 $2.075 $1.975 Units Outstanding (millions) 17.5 17.5 17.5 17.5

(1) Net income per unit is computed by dividing net income, after deduction of the general partner's allocation, by the number of common and subordinated units outstanding. The general partner's allocation is computed based upon the general partner's 2% interest plus an amount equal to incentive distributions. (2) The Partnership's 2002 fourth quarter cash distribution was declared on January 21, 2003 and will be paid on February 14, 2003 to unitholders of record as of January 31, 2003. NET INCOME YEAR ENDED DECEMBER 31, 2002 The Partnership reported 2002 net income of US$45.5 million or US$2.50 per unit compared to US$43.5 million or US$2.40 per unit in 2001. Equity income from Northern Border Pipeline amounted to US$42.8 million in 2002 compared to US$42.1 million in 2001. Northern Border Pipeline's 2002 earnings increased due to incremental revenues generated by Project 2000 and lower interest expense, resulting from lower average interest rates and lower debt balances. The increase was partially offset by the previously discussed reserve recorded by Northern Border Pipeline in the fourth quarter of 2002, higher depreciation and higher taxes other than income that were related primarily to Project 2000. Equity income from Tuscarora amounted to US$4.7 million in 2002 compared to US$3.6 million in 2001. The increase is primarily due to incremental revenues being generated from Tuscarora's expansion facilities, which were placed into service on December 1, 2002, as well as from other new transportation contracts, and lower interest expense, resulting from the capitalization of interest expense related to funds being used for Tuscarora's expansion. The Partnership also recorded US$1.5 million of general and administrative expenses and US$0.5 million of financial charges in 2002, compared to US$1.2 million and US$1.0 million in 2001, respectively. FOURTH QUARTER 2002 The Partnership reported 2002 fourth quarter net income of US$8.9 million or US$0.49 per unit compared to US$11.8 million or US$0.65 per unit in the fourth quarter of 2001. Equity income from Northern Border Pipeline amounted to US$8.2 million in the fourth quarter of 2002 compared to US$11.2 million in the fourth quarter of 2001. The decrease reflects the previously discussed reserve recorded by Northern Border Pipeline, higher depreciation expense and higher taxes other than income that were related primarily to Project 2000. The decrease was partially offset by the impact of lower interest expense in the fourth quarter of 2002. Equity income from Tuscarora amounted to US$1.4 million in the fourth quarter of 2002 compared to US$1.0 million in the fourth quarter of 2001. The increase is primarily due to incremental revenues being generated from Tuscarora's expansion facilities and lower interest expense, resulting from the capitalization of interest expense related to funds being used for Tuscarora's expansion. The Partnership also recorded US$0.4 million of general and administrative expenses and US$0.3 million of financial charges in the fourth quarter of 2002, reflecting slight increases from amounts recorded in the fourth quarter of 2001. CASH FLOW YEAR ENDED DECEMBER 31, 2002 The Partnership reported 2002 cash generated from operations of US$52.1 million compared to US$42.9 million in 2001. The increase was primarily related to higher cash distributions from the Partnership's equity investments in Northern Border Pipeline and Tuscarora. In 2002, the Partnership received cash distributions from Northern Border Pipeline amounting to US$49.2 million compared to US$42.9 million in 2001. The increase is due, primarily, to Northern Border Pipeline's incremental cash inflows from Project 2000, Northern Border Pipeline's extension and expansion into northern Indiana, which was placed into service in October 2001. The Partnership received cash distributions from Tuscarora in 2002 amounting to US$4.6 million compared to US$2.4 million in 2001. The increase reflects Tuscarora's incremental cash inflows from new transportation contracts. The increase also reflects the impact of Tuscarora making four quarterly cash distributions in 2002 versus three quarterly cash distributions in 2001, due to the timing of the implementation of Tuscarora's cash distribution policy. During 2002, the Partnership used US$7.6 million of its cash from operations to fund a portion of Tuscarora's expansion, which was partially offset by a US$0.2 million return of capital. The Partnership paid an aggregate US$37.4 million of cash distributions to unitholders and its general partner in 2002, the equivalent of US$2.025 per unit, compared to US$35.2 million in 2001, the equivalent of US$1.925 per unit. Also in 2002, the Partnership used US$10.0 million of its cash from operations to reduce the balance owing on its credit facility from US$21.5 million to US$11.5 million. FOURTH QUARTER 2002 The Partnership reported 2002 fourth quarter cash generated from operations of US$13.4 million compared to US$11.8 million in the fourth quarter of 2001. The increase reflects higher cash distributions from the Partnership's equity investments in Northern Border Pipeline and Tuscarora. In the fourth quarter of 2002, the Partnership received a cash distribution from Northern Border Pipeline amounting to US$12.6 million compared to US$11.5 million in the fourth quarter of 2001. The increase is due, primarily, to Northern Border Pipeline's incremental cash inflows from Project 2000. The Partnership received a cash distribution from Tuscarora in the fourth quarter of 2002 amounting to US$1.3 million compared to US$0.8 million in the fourth quarter of 2001. The increase reflects Tuscarora's incremental cash inflows from new transportation contracts. During the fourth quarter of 2002, the Partnership used US$3.1 million of its cash from operations to fund a portion of Tuscarora's expansion, which was partially offset by a US$0.2 million return of capital. The Partnership paid an aggregate US$9.6 million of cash distributions to unitholders and its general partner in the fourth quarter of 2002, the equivalent of US$0.525 per unit, compared to US$9.1 million in the fourth quarter of 2001, the equivalent of US$0.50 per unit. FOURTH QUARTER 2002 CASH DISTRIBUTION As previously announced, on January 21, 2003, the board of directors of the general partner declared the Partnership's fourth quarter cash distribution in the amount of US$0.525 per unit. This cash distribution will be paid on February 14, 2003 to unitholders of record as of January 31, 2003.
