Houston, Texas –November 4, 2016 – TC PipeLines, LP (NYSE: TCP) (the Partnership) today reported third quarter 2016 net income attributable to controlling interests of $58 million and distributable cash flow of $69 million.

Recent Developments

Cash Distributions – On October 20, 2016, the board of directors of our General Partner declared the Partnership's third quarter 2016 cash distribution in the amount of $0.94 per common unit payable on November 14, 2016 to unitholders of record as of November 1, 2016. The declared distribution to our General Partner will include a $1.3 million distribution for its effective two percent general partner interest and an IDR payment amounting to $1.9 million for a total distribution of $3.2 million.

Recent Conclusion of TransCanada MLP Strategy Review – TransCanada, the ultimate parent company of our General Partner, recentlyannounced the execution of an agreement to acquire all of the outstanding publicly-held common units of Columbia Pipeline Partners LP and stated that the decision to acquire Columbia Pipeline Partners completed its review of strategic alternatives for its master limited partnership (MLP) holdings following its acquisition of Columbia Pipeline Group, Inc. This acquisition will leave TransCanada with a single MLP in TC PipeLines, LP, which it describes as a core element of TransCanada's future strategy.

TransCanada is advancingCAD $25 billion of near-term capital projects, approximatelyCAD $7.5 billion of which has been invested to date with the remainder to be spent largely over the next three years. TransCanada says it intends to prudently fund its capital program in a manner that is consistent with maintaining its financial strength, including dropdowns to the Partnership.

Three Months Ended September 30, 2016Results of Operations

For the three months ended September 30, 2016, net income attributable to controlling interests increased by $9 million compared to the same period in 2015 mainly due to higher revenues from our wholly-owned subsidiaries together with higher equity earnings from unconsolidated affiliates:

Transmission revenues - the $8 million increase was primarily due to:

● higher discretionary revenues on GTN from short-term services sold to its customers; and

● new revenues from GTN's Carty lateral system which was placed in service in October 2015.

Earnings from equity investments - the $7 million increase was mainly attributable to:

● higher equity earnings from Great Lakes primarily due to higher transportation revenues resulting from higher levels of contracted volumes; and

● the acquisition of a 49.9 percent interest in PNGTS effective January 1, 2016.

Additionally, our EBITDA increased by $10 million compared to the same period in 2015 primarily due to higher transmission revenues on GTN and higher equity earnings from our equity investments.

Our Distributable cash flow remained comparable to that of the prior period primarily due to the same factors that impacted our EBITDA offset by higher distributions allocable to Class B units in 2016 compared to 2015.

Nine months Ended September 30, 2016 Cash Flow Analysis

The Partnership's net cash provided by operating activities increased by $27 million for the nine months ended September 30, 2016 compared to the same period in 2015 primarily due to higher earnings.

The Partnership's net cash used in investing activities decreased by $117 million as we invested a lesser amount for our recent acquisition of PNGTS compared to our investment during the same period in 2015. In 2015, we paid $264 million to acquire the remaining 30 percent interest in GTN compared to $193 million paid for the acquisition of a 49.9 percent interest in PNGTS in 2016. Additionally, we received higher net distributions in 2016 from our equity investments offset by higher capital expenditures in 2015 due to expenditures related to the construction of the Carty Lateral.

The Partnership's net cash provided by financing activities decreased by $113 million in the nine months ended September 30, 2016 compared to the same period in 2015 primarily due to the net effect of:

● $188 million decrease in net issuances of debt in 2016 as compared with 2015;

● $92 million increase in our ATM equity issuances in 2016 as compared with 2015;

● $15 million increase in distributions paid to our common units including our General Partner's two percent share and its related IDRs;

● $12 million of distributions paid to Class B units in 2016; and

● $9 million of distributions paid to TransCanada as the non-controlling interest owner of GTN until March 31, 2015.

At September 30, 2016, the Partnership's available borrowing capacity under its $500 million credit facility was $280 million.

The non-GAAP measures presented as part of this release 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. The calculation of EBITDA and Distributable Cash Flow are reconciled to Net Income, the most comparable GAAP measure, and are included as part of this release.

(a) Net income per common unit is computed by dividing net income attributable to controlling interests, after deduction of amounts attributable to the General Partner and Class B units, by the weighted average number of common units outstanding. The amount allocable to the General Partner equals an amount based upon the General Partner's effective two percent general partner interest, plus an amount equal to incentive distributions. For the year ending December 31, 2016, the amount allocable to the Class B units is equal to 30 percent of GTN's annual distributable cash flow, less the threshold amount of $20 million (2015 – less $15 million). During the six months ended June 30, 2016, the threshold was exceeded and during the nine months ended September 30, 2016, 30 percent of GTN's total distributable cash flow amounted to $32 million. As a result, $12 million of net income attributable to controlling interests was allocated to the Class B units at September 30, 2016, of which $1 million and $11 million was allocated during the three months ended June 30, 2016 and September 30, 2016, respectively. From April 1, 2015 to September 30, 2015, 30 percent of GTN's total distributable cash flow was $17 million. As a result, $2 million of net income attributable to controlling interests was allocated to the Class B units for both the three and nine months ended September 30, 2015.

(a) As a result of the application of ASU no. 2015-03 and similar to the presentation of debt discounts, debt issuance costs of $7 million at December 31, 2015 previously reported as other assets in the balance sheet were reclassified as an offset against debt.

(b) In connection with the late filing of an employee-related Form 8-K with the SEC, we may have been ineligible to use the then effective shelf registration statement upon the filing of our 2015 Form 10-K. As a result, it was determined that the 1.6 million common units that were issued after the filing of our Form 10-K on February 26, 2016 up to and including June 30, 2016 under our ATM program may be subject to rescission rights for an amount equal to the purchase price paid for the units (or the difference between the purchase price paid and the price at which the units were sold, assuming a loss), plus statutory interest and less any distributions paid, upon the return of the units to us. These rights expire one year from the date of purchase of the unit. No unitholder has claimed or attempted to exercise any rescission rights to date. As a result, at September 30, 2016, the Partnership classified all the 1.6 million common units described above, outside of equity given the potential redemption feature which is not within the control of the Partnership. These units are treated as outstanding for financial reporting purposes. The total amount transferred  outside of equity was approximately $83 million which includes interest and less distributions paid and includes our General Partner's share to maintain its effective two percent interest.

For more information refer to our Quarterly Report on Form 10-Q for the period ended September 30, 2016 as filed with the SEC.

(a) Interest expense as presented here includes net realized loss related to interest rate swaps.

(b) Amounts here are calculated in accordance with the cash distribution policies of these entities.  Distributions from each of our equity investments represent our respective share of these entities' quarterly distributable cash during the current reporting period.

(c) Our equity investee PNGTS has $22 million of senior secured notes payment due in 2016, of which the Partnership's share is approximately $11 million. While PNGTS debt repayments are not funded with cash calls to its owners, PNGTS has historically funded its scheduled debt repayments and other cash needs such as tax payments, by adjusting its available cash for distribution, which effectively reduces the net cash that we actually receive as distributions from PNGTS.  Accordingly, these amounts represent our 49.9 percent share of distributions from PNGTS' available cash before our proportionate share of the total debt repayment of PNGTS.

(d) Distributions to non-controlling interests represent the respective share on our consolidated entities' quarterly distributable cash not owned by us during the current reporting period.

(e) The Partnership's maintenance capital expenditures include cash expenditures made to maintain, over the long term, our assets' operating capacity, system integrity and reliability.  Accordingly, this amount represents the Partnership's and its consolidated subsidiaries' maintenance capital expenditures and does not include the Partnership's share of maintenance capital expenditures on our equity investments. Such amounts are reflected in "Distributions from equity investments" as those amounts are withheld by those entities from their quarterly distributable cash.

(f) Distributions declared to the General Partner for the three and nine months ended September 30, 2016 included an incentive distribution of approximately $2 million and $5 million, respectively (2015 -  $1 million and $2 million).

(g) During the nine months ended September 30, 2016, 30 percent of GTN's total distributions amounted to $32 million. As a result of exceeding the $20 million threshold since the end of the second quarter of 2016, $12 million was allocated to the Class B units for the nine months ended September 30, 2016, of which $1 million and $11 million were allocated during the three months ended June 30, 2016 and September 30, 2016, respectively. From April 1 to September 30, 2015, 30 percent of GTN's total distributable cash flow amounted to $17 million.  As a result, $2 million of net income attributable to controlling interests was allocated to the Class B units for both the three and nine months ended September 30, 2015.
