TransCanada Reports 2009 Net Income of $1.4 Billion

Common Share Dividend Increased by 5 Per Cent

CALGARY, Alberta – February 23, 2010 – TransCanada Corporation (TSX, NYSE: TRP) (TransCanada or the Company) today announced net income applicable to common shares for fourth quarter 2009 of $381 million or $0.56 per share.  For the year ended December 31, 2009, net income applicable to common shares was $1.4 billion or $2.11 per share.  TransCanada’s Board of Directors also declared a quarterly dividend of $0.40 per common share. The new quarterly dividend equates to $1.60 per common share on an annualized basis, an increase of five per cent.

“Our 2009 financial results highlight our ability to generate strong earnings and cash flow from a diverse portfolio of North American energy infrastructure assets” said Hal Kvisle, TransCanada’s president and chief executive officer. “Looking forward, we expect that our $22 billion capital program will lead to significant growth in cash flow and earnings over the next five years as a number of attractive, low-risk projects are placed into service. This has enabled our Board of Directors to increase the dividend on common shares for the tenth consecutive year.”

Mr. Kvisle noted that in 2009 TransCanada continued to make substantial progress on a number of major initiatives while maintaining its strong financial position.

“We have invested approximately $10 billion in large-scale, multi-year projects such as the Keystone Oil Pipeline System, the Alberta System’s North Central Corridor expansion, the Bruce Power refurbishment and restart project and the development of three large natural gas-fired power plants,” said Mr. Kvisle. “Each project is expected to generate significant long-term earnings and cash flow on commencement of operations.”

“TransCanada is well positioned to fund the remaining portion of this unprecedented capital program,” Mr. Kvisle added. “While the carrying costs and dilution associated with our prudent approach to financing this multi-year program will have a near-term impact on our earnings and cash flow per share, our growing internally generated cash flow and our strong financial position provide us with financial flexibility going forward.”

Fourth Quarter and Year-End 2009 Highlights

(All financial figures are unaudited and in Canadian dollars unless noted otherwise)

§   For fourth quarter

o   Net income applicable to common shares of $381 million or $0.56 per share

o   Comparable earnings of $328 million or $0.48 per share

o   Comparable EBITDA of $965 million

o   Funds generated from operations of $850 million

§   For the year ended December 31

o   Net income applicable to common shares of $1.4 billion or $2.11 per share

o   Comparable earnings of $1.3 billion or $2.03 per share

o   Comparable EBITDA of $4.1 billion

o   Funds generated from operations of $3.1 billion

§   Invested $6.3 billion to advance unprecedented $22 billion capital program

Comparable earnings for fourth quarter 2009 were $328 million ($0.48 per share) compared to $271 million ($0.46 per share) in fourth quarter 2008.  The increase was primarily due to higher earnings from Natural Gas Storage, higher realized power prices at Bruce B, incremental earnings from Portlands Energy Centre, which was placed into service in April 2009 and lower interest expense from increased capitalization of interest related to the Company’s large capital growth program. Partially offsetting these increases were lower realized power prices in Western Power and U.S. Power and business development costs associated with the Alaska pipeline project.  Earnings per share were reduced by the dilutive impact in fourth quarter 2009 of a 14 per cent increase in the average number of common shares outstanding following the issuance of 58.4 million common shares in second quarter 2009 and 35.1 million common shares in fourth quarter 2008.  Proceeds from these offerings were used to partially fund capital growth projects, including the acquisition of additional interests in Keystone, for general corporate purposes and to repay short term indebtedness.  TransCanada’s $22 billion capital program is expected to generate significant cash flow and earnings over the next five years as projects commence operations.

FOURTH QUARTER NEWS RELEASE 2009

Comparable earnings for the year ended December 31, 2009 of $1.325 billion ($2.03 per share) increased $46 million compared to $1.279 billion ($2.25 per share) for 2008.  The increase in comparable earnings was primarily due to higher earnings from the Alberta System, the start up of Portlands Energy Centre and Carleton Wind Farm and higher realized power prices at Bruce Power.  Partially offsetting these increases were lower realized power prices on lower sales volumes in the Alberta and New England power markets.  On a per share basis, in 2009, earnings were reduced by the dilutive impact of an increase in the average number of outstanding common shares following the issuance of 58.4 million common shares, 35.1 million common shares and 34.7 million common shares in second quarter 2009, fourth quarter 2008 and second quarter 2008, respectively.  Proceeds from these offerings were used to partially fund acquisitions and capital projects, for general corporate purposes and to repay short term indebtedness.

Notable recent developments in Pipelines, Energy and Corporate include:

Pipelines:

§   Commissioning of the first phase of the Keystone Oil Pipeline System (Keystone), extending from Hardisty, Alberta to Wood River and Patoka, Illinois with an initial nominal capacity of 435,000 barrels per day (Bbl/d), began in late 2009 and commercial operations are expected to commence mid-2010.

In September 2009, the National Energy Board (NEB) held a hearing to review the application for the new Canadian facilities required for the Keystone Gulf Coast expansion. A decision from the NEB is expected in first quarter 2010, approving a certificate for the construction and operation of the facilities, subject to Governor-in-Council approval, and the proposed tolling methodology. Facility permits for the U.S. portion of the expansion are expected by fourth quarter 2010. Construction of the expansion facilities is anticipated to commence in first quarter 2011 following the receipt of the necessary regulatory approvals. 

TransCanada expects Keystone to begin generating EBITDA in 2010 with EBITDA increasing through 2011, 2012 and 2013 as subsequent phases are placed in service. Contracted volumes of 217,500 Bbl/d will increase to 910,000 Bbl/d from 2010 through to 2013 in conjunction with commencement of the Cushing and Gulf Coast phases. Based on these current long-term commitments, TransCanada expects to generate EBITDA of approximately US$1.2 billion from Keystone in 2013, its first full year of commercial operation servicing both the U.S. Midwest and Gulf Coast markets. If volumes were to increase to 1.1 million Bbl/d, the full commercial design of the system, TransCanada would generate annual EBITDA of approximately US$1.5 billion from Keystone. In the future, Keystone could be economically expanded from 1.1 million Bbl/d to 1.5 million Bbl/d in response to additional market demand.

§   TransCanada and ExxonMobil continued to advance the Alaska pipeline project by filing an open season plan in the first quarter of 2010 with the U.S. Federal Energy Regulatory Commission (FERC). The filing was made to obtain approval to conduct the first natural gas pipeline open season to develop Alaska’s vast natural gas resources. If the FERC approves the plan, the project will commence its open season in April 2010.

§   TransCanada and the other co-venture companies involved in the Mackenzie Gas Pipeline Project (MGP) continue to pursue approval of the proposed project, focusing on obtaining regulatory approval and the Canadian government’s support of an acceptable fiscal framework. The regulatory process reached a milestone in late December 2009 with the release of the Joint Review Panel’s report on environmental and socio-economic factors relating to the project. That report has been submitted into the NEB review process for approval of the project, which is scheduled to conclude in April 2010 with final arguments. A decision is currently expected by fourth quarter 2010.

FOURTH QUARTER NEWS RELEASE 2009

§   In November 2009, the NEB concluded a public hearing process on TransCanada’s application for approval to construct and operate the Groundbirch pipeline, which is comprised of a 77 kilometre (km) (48 miles) natural gas pipeline and related above ground facilities. Upon approval, the Groundbirch pipeline will be an extension of the Alberta System and is expected to connect natural gas supply primarily from the Montney shale gas formation in northeast B.C. to existing infrastructure in northwest Alberta. Construction of the Groundbirch pipeline is expected to commence in July 2010 with final completion anticipated in November 2010. A decision from the NEB is expected in first quarter 2010.The proposed project is expected to cost approximately $200 million with secured firm transportation contracts that will reach 1.1 billion cubic feet per day (Bcf/d) by 2014.

§   Total contractual commitments for the Alberta System’s Horn River project have increased from 378 million cubic feet per day (mmcf/d) to 503 mmcf/d by 2014 as a result of newly contracted volumes from a recently announced natural gas processing facility that will be located in the Horn River area of British Columbia.  The Horn River project will connect new shale gas supply in the Horn River development region to the Alberta System. As part of the Horn River project, in November 2009, TransCanada entered into an agreement to acquire the Ekwan Pipeline from EnCana Corporation. This acquisition is expected to close in September 2011. In February 2010, TransCanada filed an application with the NEB for approval to construct and operate the Horn River project, including acquisition of the Ekwan pipeline. Subject to regulatory approvals, the Horn River project is anticipated to be placed in-service in second quarter 2012.

§   TransCanada continued work on the 160 km (99 miles) Red Earth section of the North Central Corridor (NCC) pipeline expansion of the Alberta System that is expected to be completed by April 2010. The 140 km (87 miles) North Star section was completed and two 13 megawatt (MW) compressor units at the Meikle River compressor station were operational on May 15, 2009 and August 21, 2009, respectively.

§   Regulatory approvals were received in December 2009 for the approximate 305 km (190 miles), US$320 million Guadalajara natural gas pipeline project in Mexico.  Construction is underway with an expected in-service date of first quarter 2011.

§   TransCanada is expecting FERC approval in March 2010 of the Bison pipeline project, a proposed 487 km (303 miles) natural gas pipeline. Once approval is received, TransCanada will commence construction in May 2010. The project has shipping commitments for approximately 407 mmcf/d and is expected to be in service in fourth quarter 2010. The capital cost of the Bison pipeline project is estimated to be US$600 million.

§   During 2009, TransCanada negotiated a Rate Design Settlement for the Alberta System, which provided for a new rate design for the existing system and expansions which addresses the evolving nature of the Alberta System and the commercial and operational integration of ATCO Pipelines. The changes are expected to improve the Alberta System services by making them more consistent and adding flexibility for customers. TransCanada filed a combination application with the NEB on November 27, 2009 for approval of both the Rate Design Settlement and the integration of commercial and operational services on the Alberta System and ATCO Pipelines’ system in Alberta. A final decision is expected from the NEB by mid-2010 with implementation occurring within 12 months following approval.

Energy:

§   In October 2009, TransCanada placed into service the first phase of Kibby Wind, which included 22 turbines capable of producing 66 MW of power. Construction continues on the 66 MW second phase of the project, which includes the installation of an additional 22 turbines. The second phase is expected to be in service in third quarter 2010.

FOURTH QUARTER NEWS RELEASE 2009

§   Construction of the 683 MW Halton Hills power plant in Ontario and the 575 MW Coolidge generating station in Arizona continued to progress on schedule with in service dates of third quarter 2010 and second quarter 2011, respectively.

§   Clearing for the 58 MW Montagne-Sèche wind farm was completed in fourth quarter of 2009. The Montagne-Sèche project and phase one of the Gros-Morne wind farm are expected to be operational in 2011.  Gros-Morne phase two is expected to be operational in 2012. These are the fourth and fifth Québec-based wind farms of Cartier Wind, which is 62 per cent owned by TransCanada.

§   Construction activity is continuing on the refurbishment and restart of Bruce A Units 1 and 2 with a focus on the reassembly of the reactors and other related activities. As of December 31, 2009, Bruce A had incurred approximately $3.2 billion in costs for the refurbishment and restart of these units and approximately $0.2 billion for the refurbishment of Units 3 and 4. TransCanada believes that its share of the total capital cost to complete the Unit 1 and 2 refurbishment and restart program will be approximately $2 billion. The bulk of the highly technical, high-risk work on this project is now finished or nearing completion. Although a significant amount of work remains to be completed, most of the work is conventional power plant construction activity. A project optimization plan implemented by Bruce Power last year is achieving success in improving productivity. TransCanada expects that Unit 2 will be restarted in mid-2011, with Unit 1 to follow approximately four months later.

Bruce Power continues to advance an initiative to further extend the operating lives of Units 3 and 4. Unit 4 is now expected to continue to operate beyond 2018 and plans are in place to implement an extensive maintenance program that, if successful and approved by the Canadian Nuclear Safety Commission would see the life of Unit 3 extended for a similar period of time.

§   TransCanada’s open seasons for capacity on its proposed Zephyr and Chinook power transmission line projects closed in December 2009. A comprehensive review of the bids will be undertaken. Each project would be capable of delivering primarily renewable (wind) power originating in Wyoming (Zephyr) and Montana (Chinook) to Nevada.

Corporate:

§   The Board of Directors of TransCanada declared a quarterly dividend of $0.40 per common share, an increase of five per cent, for the quarter ending March 31, 2010, on TransCanada’s outstanding common shares.

§   TransCanada is well positioned to fund its existing capital program through its growing internally-generated cash flow, its dividend reinvestment and share purchase plan, and its continued access to capital markets. TransCanada will also continue to examine opportunities for portfolio management, including an ongoing role for TC PipeLines, LP in financing its capital program.

Teleconference – Audio and Slide Presentation:

Non-GAAP Measures

TransCanada uses the measures "comparable earnings", "comparable earnings per share", "earnings before interest, taxes, depreciation and amortization" (EBITDA), "comparable EBITDA", "earnings before interest and taxes" (EBIT), "comparable EBIT" and "funds generated from operations" in this news release. These measures do not have any standardized meaning prescribed by Canadian generally accepted accounting principles (GAAP). They are, therefore, considered to be non-GAAP measures and may not be comparable to similar measures presented by other entities. Management of TransCanada uses these non-GAAP measures to improve its ability to compare financial results among reporting periods and to enhance its understanding of operating performance, liquidity and ability to generate funds to finance operations. These non-GAAP measures are also provided to readers as additional information on TransCanada’s operating performance, liquidity and ability to generate funds to finance operations.

EBITDA is an approximate measure of the Company’s pre-tax operating cash flow. EBITDA comprises earnings before deducting interest and other financial charges, income taxes, depreciation and amortization, and non-controlling interests. EBIT is a measure of the Company’s earnings from ongoing operations. EBIT comprises earnings before deducting interest and other financial charges, income taxes and non-controlling interests.

TRANSCANADA [8

FOURTH QUARTER NEWS RELEASE 2009

Management uses the measures of comparable earnings, comparable EBITDA and comparable EBIT to better evaluate trends in the Company’s underlying operations. Comparable earnings, comparable EBITDA and comparable EBIT comprise net income applicable to common shares, EBITDA and EBIT, respectively, adjusted for specific items that are significant, but are not reflective of the Company’s underlying operations in the period. Specific items are subjective, however, management uses its judgement and informed decision-making when identifying items to be excluded in calculating comparable earnings, comparable EBITDA and comparable EBIT, some of which may recur. Specific items may include but are not limited to certain income tax refunds and adjustments, gains or losses on sales of assets, legal and bankruptcy settlements, and certain fair value adjustments. The table in the "Consolidated Results of Operations" section of this news release presents a reconciliation of comparable earnings, comparable EBITDA, comparable EBIT and EBIT to net income and net income applicable to common shares. Comparable earnings per share is calculated by dividing comparable earnings by the weighted average number of common shares outstanding for the period.

Funds generated from operations comprises net cash provided by operations before changes in operating working capital. A reconciliation of funds generated from operations to net cash provided by operations is presented in the Fourth Quarter 2009 Financial Highlights table in this news release.

TransCanada’s net income was $387 million and net income applicable to common shares was $381 million or $0.56 per share in fourth quarter 2009 compared to $277 million or $0.47 per share in fourth quarter 2008. The $104 million increase in net income applicable to common shares reflected:

·   decreased EBIT from Pipelines primarily due to the negative impact of a weaker U.S. dollar on Pipeline’s U.S. operations and increased business development costs related to the Alaska pipeline project. These decreases were partially offset by an $18 million after tax ($29 million pre-tax) dilution gain resulting from TransCanada’s reduced ownership interest in PipeLines LP following PipeLines LP’s public issuance of common units.

TRANSCANADA [11

FOURTH QUARTER NEWS RELEASE 2009

·   decreased EBIT from Energy primarily due to lower power prices in Western Power and U.S. Power, and the impact of a weaker U.S. dollar on Energy’s U.S. operations, partially offset by higher contribution from the Natural Gas Storage business due to increased third party storage revenues and increased earnings as a result of the start up of Portlands Energy.

·   decreased interest expense primarily due to increased capitalized interest, reduced losses from changes in the fair value of interest rate derivatives used to manage TransCanada’s exposure to fluctuating interest rates and the positive impact of a weaker U.S. dollar. These decreases were partially offset by incremental interest expense for new debt issuances in 2009.

·   increased interest income and other due to the positive impact of a weaker U.S. dollar on working capital balances and changes in the fair value of derivatives used to manage the Company’s exposure to foreign exchange rate fluctuations; and

·   decreased income tax expense primarily due to positive income tax adjustments in fourth quarter 2009, including $30 million resulting from a reduction in the Province of Ontario’s corporate income tax rates, partially offset by higher pre-tax income.

The increase in earnings per share in fourth quarter 2009 was partially offset by a 14 per cent increase in the average number of common shares outstanding, in fourth quarter 2009 compared to fourth quarter 2008, following the Company’s issuance of 58.4 million and 35.1 million common shares in second quarter 2009 and fourth quarter 2008, respectively.

Comparable earnings in fourth quarter 2009 increased $57 million or $0.02 per share to $328 million or $0.48 per share, compared to $271 million or $0.46 per share for the same period in 2008. Comparable earnings in fourth quarter 2009 excluded the $18 million after tax dilution gain resulting from TransCanada’s reduced ownership in PipeLines LP and the $30 million of favourable income tax adjustments. Comparable earnings in fourth quarter 2009 and 2008 also excluded net unrealized after tax gains of $5 million ($7 million pre-tax) and $6 million ($7 million pre-tax), respectively, resulting from changes in the fair value of proprietary natural gas inventory in storage and natural gas forward purchase and sale contracts.

On a consolidated basis, the impact of changes in the U.S. dollar on U.S. Pipelines and Energy EBIT is largely offset by the impact on U.S. dollar interest expense. The resultant net exposure is managed using derivatives thereby effectively reducing the Company’s exposure to changes in foreign exchange rates. The average U.S. dollar exchange rate for the fourth quarter and year ended December 31, 2009 was 1.06 and 1.14, respectively (2008 - 1.21 and 1.07, respectively).

In 2009, net income was $1,380 million and net income applicable to common shares was $1,374 million or $2.11 per share compared to net income of $1,440 million or $2.53 per share in 2008. Net income applicable to common shares in 2009 included the $30 million of favourable income tax adjustments and the $18 million after tax dilution gain resulting from TransCanada’s reduced interest in PipeLines LP. Net income in 2008 included $152 million of after tax gains on shares received by GTN and Portland from the Calpine bankruptcy settlements, $10 million after tax of GTN lawsuit settlement proceeds and a $27 million after tax writedown of costs previously capitalized for the Broadwater liquefied natural gas (LNG) project. Net income in 2008 also included $26 million of favourable income tax adjustments from an internal restructuring and realization of losses.

Comparable earnings for 2009 were $1,325 million or $2.03 per share compared to $1,279 million or $2.25 per share for 2008 and excluded the above-noted items. Comparable earnings increased $46 million and decreased $0.22 per share in 2009 compared to 2008. The increase in comparable earnings reflects:

TRANSCANADA [12

FOURTH QUARTER NEWS RELEASE 2009

•   increased comparable EBIT from Pipelines primarily due to higher earnings from the Alberta System revenue requirement settlement and the positive impact in 2009 of a stronger U.S. dollar on Pipelines’ U.S. operations, partially offset by increased costs for developing new Pipelines projects, primarily the Alaska pipeline project;

•   decreased comparable EBIT from Energy primarily due to lower power prices and a decreased demand for power in Western Power and U.S. Power, reflecting the downturn in the North American economy, partially offset by increased earnings from the start up of Portlands Energy and the Carleton phase of the Cartier Wind project, and higher realized power prices for Bruce Power;

•   increased comparable EBIT losses from Corporate primarily due to higher support services costs, reflecting a growing asset base;

•   increased interest expense as a result of long-term debt issuances in the second half of 2008 and first quarter 2009 and the negative impact of a stronger U.S. dollar. These increases were partially offset by an increase in capitalized interest relating to Keystone and other capital projects and reduced losses from changes in the fair value of derivatives used to manage TransCanada’s exposure to fluctuating interest rates;

•   the positive impact of a weakening U.S. dollar throughout 2009 on working capital balances and higher gains from derivatives used to manage the Company’s exposure to foreign exchange rate fluctuations;

•   decreased income tax expense due to lower pre-tax earnings, higher income tax savings from income tax rate differentials and other positive income tax adjustments in 2009; and

•   a reduction in non-controlling interests due to Portland’s portion of the Calpine bankruptcy settlements recorded in 2008, partially offset by higher PipeLines LP earnings in 2009.

Earnings per share in 2009 and 2008 was reduced by the increase in the average number of shares outstanding following the Company’s issuance of 58.4 million, 35.1 million and 34.7 million common shares in second quarter 2009, fourth quarter 2008 and second quarter 2008, respectively. The shares were issued to partially finance TransCanada’s acquisitions and extensive capital growth program.

Results from each of the segments for fourth quarter 2009 are discussed further in the Pipelines, Energy and Corporate sections of this news release.

Pipelines

Pipelines comparable EBIT was $488 million in fourth quarter 2009 compared to $556 million for the same period in 2008. Comparable EBIT excluded the $29 million pre-tax dilution gain resulting from a reduction in TransCanada’s ownership interest in PipeLines LP following PipeLines LP’s public issuance of common units in fourth quarter 2009.

Canadian Pipelines

Canadian Mainline’s net income for fourth quarter 2009 decreased $2 million to $72 million from $74 million for the same period in 2008. Net income for fourth quarter 2009 reflected a lower average investment base and a lower rate of return on common equity (ROE) as determined by the National Energy Board (NEB) of 8.57 per cent in 2009 compared to 8.71 per cent in 2008, partially offset by higher OM&A cost savings.

Canadian Mainline’s EBITDA for fourth quarter 2009 of $282 million decreased $18 million compared to the same period in 2008 primarily due to lower revenues as a result of a recovery of lower income taxes and a lower overall return on average investment base in the 2009 tolls, partially offset by higher OM&A cost savings.

The Alberta System’s net income was $45 million in fourth quarter 2009 compared to $48 million for the same period in 2008. Earnings in 2009 and 2008 reflect the impact of the 2008-2009 Revenue Requirement Settlement originally approved by the Alberta Utilities Commission (AUC) in December 2008 and subsequently approved by the NEB in December 2009.

The Alberta System's EBITDA was $193 million in fourth quarter 2009 compared to $152 million for the same period in 2008. Fourth quarter 2009 EBITDA reflects higher revenues as a result of the recovery of higher depreciation and income taxes, partially offset by lower settlement earnings.

EBITDA from Other Canadian Pipelines was $15 million for fourth quarter 2009 compared to $11 million for the same period in 2008. The increase in fourth quarter 2009 was primarily due to an adjustment to TQM’s cost of capital for 2009.

U.S. Pipelines

ANR’s EBITDA for fourth quarter 2009 was $84 million compared to $99 million for the same period in 2008. The decrease in EBITDA in fourth quarter 2009 was primarily due to the negative impact of a weaker U.S. dollar.

GTN’s EBITDA for fourth quarter 2009 decreased $9 million from the same period in 2008 primarily due to the negative impact of a weaker U.S. dollar and the sale of North Baja to PipeLines LP.

EBITDA for the remainder of the U.S. Pipelines was $132 million for fourth quarter 2009 compared to $144 million for the same period in 2008. The decrease in fourth quarter 2009 compared to fourth quarter 2008 was primarily due to the negative impact of a weaker U.S. dollar on U.S. Pipelines operations, partially offset by the acquisition of North Baja by PipeLines LP.

Business Development

Pipelines business development comparable EBITDA losses increased $27 million in fourth quarter 2009 compared to the same period in 2008 primarily due to increased business development costs related to the Alaska pipeline project.

Western Power’s EBITDA of $61 million and power revenues of $203 million in fourth quarter 2009 decreased $67 million and $95 million, respectively, compared to the same period in 2008. These decreases were primarily due to lower earnings from the Alberta power portfolio resulting from lower overall realized power prices on lower volumes of power sold. The reduction in power prices and sales volumes reflected reduced demand for electricity in Alberta as a result of the North American economic slowdown. Average spot market power prices in Alberta decreased 51 per cent, or $49 per MWh, in fourth quarter 2009 compared to fourth quarter 2008.

TRANSCANADA [17

FOURTH QUARTER NEWS RELEASE 2009

Western Power’s commodity purchases resold decreased $13 million in fourth quarter 2009 compared to the same period in 2008 primarily due to lower purchased power volumes as a result of the reduced demand for electricity in Alberta.

Eastern Power’s EBITDA of $56 million and power revenues of $72 million for fourth quarter 2009 increased $13 million and $18 million, respectively, compared to the same period in 2008. These increases were primarily due to incremental earnings from Portlands Energy which went into service in April 2009.

Plant operating costs and other, which includes fuel gas consumed in generation, of $49 million for fourth quarter 2009 decreased from the same period in 2008 primarily due to lower prices for natural gas fuel in Western Power, partially offset by incremental fuel consumed at Portlands Energy.

Approximately 77 per cent of Western Power sales volumes were sold under contract in fourth quarter 2009, compared to 68 per cent in fourth quarter 2008. To reduce its exposure to spot market prices on uncontracted volumes, as at December 31, 2009, Western Power had entered into fixed-price power sales contracts to sell approximately 8,400 gigawatt hours (GWh) for 2010 and 6,000 GWh for 2011.

In fourth quarter 2009 and 2008, 100 per cent of Eastern Power sales volumes were sold under contract and are expected to continue to be fully sold under contract for 2010 and 2011.

FOURTH QUARTER NEWS RELEASE 2009

TransCanada’s proportionate share of Bruce Power’s comparable EBITDA of $70 million in fourth quarter 2009 was consistent with fourth quarter 2008.  Increased revenues from higher realized prices and an annual lease expense reduction at Bruce B were offset by higher non-lease operating expenses and lower volumes resulting from an increase in outage days.

TransCanada’s proportionate share of Bruce A’s comparable EBITDA decreased $28 million to a loss of $29 million in fourth quarter 2009 compared to a loss of $1 million in fourth quarter 2008 as a result of decreased volumes and higher operating costs due to an unplanned extension of the two planned outages which were rescheduled from March 2009 to September 2009. Bruce A’s availability in fourth quarter 2009 was 47 per cent as a result of 84 outage days compared to an availability of 62 per cent and 63 outage days in the same period in 2008.

TransCanada’s proportionate share of Bruce B’s comparable EBITDA increased $28 million to $99 million in fourth quarter 2009 compared to fourth quarter 2008 primarily due to higher realized prices resulting from the recognition of payments received pursuant to the floor price mechanism in Bruce B’s contract with the Ontario Power Authority (OPA), as well as a reduction in annual lease expense. Provisions in the Bruce B lease agreement with Ontario Power Generation allowed for a reduction in annual lease expense as the annual Ontario spot price for electricity was less than $30 per MWh.

Amounts received under the Bruce B floor price mechanism in any calendar year are subject to repayment if the annual average spot price exceeds the average annual floor price. In 2009, the annual average spot price did not exceed the annual average floor price, therefore, no amounts recorded in revenue in 2009 will be repaid. In 2008, Bruce B did not recognize into revenue any of the support payments received under the floor price mechanism as the annual average spot price exceeded the annual average floor price.

TransCanada’s share of Bruce Power’s generation in fourth quarter 2009 decreased to 2,753 GWh compared to 3,195 GWh in fourth quarter 2008, partially due to periods in fourth quarter 2009 when the Independent Electricity System Operator (IESO) curtailed certain units at Bruce Power to address surplus baseload generation in Ontario. During these unit curtailments by the IESO, Bruce Power received deemed generation payments at OPA contract prices. Including deemed generation, the Bruce Power units’ combined average availability was 80 per cent in fourth quarter 2009 compared to 86 per cent in fourth quarter 2008.

Under a contract with the OPA, all of the output from Bruce A in fourth quarter 2009 was sold at a fixed price of $64.45 per MWh (before recovery of fuel costs from the OPA) compared to $63.00 per MWh in fourth quarter 2008. All output from the Bruce B units were subject to a floor price of $48.76 per MWh in fourth quarter 2009 and $47.66 per MWh in fourth quarter 2008. Both the Bruce A and Bruce B contract prices are adjusted annually for inflation on April 1.

Bruce B also enters into fixed-price contracts where the difference between the contract price and the spot price is received. Bruce B’s realized price of $62 per MWh in fourth quarter 2009 reflects revenues recognized from both the floor price mechanism and contract sales, compared to $57 per MWh in the same period in 2008 during which no revenues were recognized under the floor price mechanism. At December 31, 2009, Bruce B had sold forward approximately 2,100 GWh and 500 GWh, representing TransCanada’s proportionate share, for 2010 and 2011, respectively.

U.S. Power’s comparable EBITDA for fourth quarter 2009 of $29 million decreased $21 million compared to the same period in 2008. The decrease was primarily due to lower overall realized power prices and the impact of a weaker U.S. dollar, partially offset by incremental revenue realized on contract sales in New England. While average spot market power prices in New England decreased in fourth quarter 2009 compared to fourth quarter 2008, the majority of U.S. Power’s sales volumes are sold at contracted prices.

U.S. Power’s power revenues for fourth quarter 2009 of $233 million decreased from $282 million for the same period in 2008 due to the impact of a weaker U.S. dollar and lower realized power prices, partially offset by higher volumes of power sold, higher revenues from Ravenswood as a result of the expiry of a tolling agreement with a third party at December 31, 2008 and an increase in financial contract sales. Beginning in 2009, the marketing output of Ravenswood has been managed in a manner consistent with the Company’s other northeast U.S. portfolio of assets.

FOURTH QUARTER NEWS RELEASE 2009

Power commodity purchases resold of $125 million for fourth quarter 2009 decreased from $159 million in the same period in 2008 primarily due to the impact of a weaker U.S. dollar in 2009 and a lower overall cost per GWh on purchased power volumes.

Other revenues and other power commodity purchases resold of $145 million and $120 million, respectively, increased in fourth quarter 2009 compared to the same period in 2008 due to an increase in the volume of natural gas sold, partially offset by the impact of a weaker U.S. dollar in 2009.

Plant operating costs and other of $134 million for fourth quarter 2009 increased $30 million from the same period in 2008 due to higher costs at Ravenswood as a result of the expiry of a tolling agreement with a third party on December 31, 2008, partially offset by the impact of a weaker U.S. dollar in 2009.

In fourth quarter 2009, two per cent of power sales volumes were sold into the spot market, compared to one per cent for the same period in 2008.  To reduce its exposure to spot market prices on uncontracted volumes, as at December 31, 2009, U.S. Power had entered into fixed-price power sales contracts to sell approximately 10,300 GWh for 2010 and 5,400 GWh for 2011, including financial contracts to economically hedge the price of forecasted generation. Certain contracted volumes are dependent on customer usage levels and actual amounts contracted in future periods will depend on market liquidity and other factors.

Natural Gas Storage

Natural Gas Storage’s comparable EBITDA for fourth quarter 2009 was $49 million compared to $34 million for the same period in 2008. The $15 million increase in EBITDA in fourth quarter 2009 was primarily due to increased third party storage revenues as a result of higher realized seasonal natural gas price spreads. Comparable EBITDA excluded net unrealized gains of $7 million in fourth quarter 2009 (2008 – gains of $7 million), resulting from changes in the fair value of proprietary natural gas inventory in storage and natural gas forward purchase and sale contracts.

Business Development

Business development comparable EBITDA losses of $6 million in fourth quarter 2009 decreased $11 million compared to the same period in 2008 primarily due to the timing of certain key projects.

Depreciation and Amortization

Depreciation and amortization for fourth quarter 2009 of $86 million increased $6 million compared to the same period in 2008, primarily due to Portlands Energy which went into service in April 2009.

Corporate

Corporate EBIT losses for fourth quarter 2009 were $28 million compared to losses of $33 million for the same period in 2008. The decreases in EBIT losses were primarily due to lower support service costs in fourth quarter 2009.

Interest expense for fourth quarter 2009 decreased $142 million to $184 million from $326 million in fourth quarter 2008. The decrease reflected increased capitalized interest to finance the Company’s larger capital growth program in 2009, primarily due to Keystone construction, and a decrease in U.S. dollar-denominated interest expense due to the impact of a weaker U.S. dollar in fourth quarter 2009 compared to fourth quarter 2008. Interest expense also decreased due to reduced losses in fourth quarter 2009 compared to 2008 from changes in the fair value of derivatives used to manage the Company’s exposure to interest rate fluctuations. These decreases were partially offset by incremental interest expense on new debt issues of US$2.0 billion in January 2009 and $700 million in February 2009.

Interest Income and Other for fourth quarter 2009 was income of $22 million compared to an expense of $4 million for the same period in 2008. The increase in income of $26 million in fourth quarter 2009 was primarily due to the positive impact of a weaker U.S. dollar on working capital balances and higher gains from changes in the fair value of derivatives used to manage the Company’s exposure to foreign exchange rate fluctuations in fourth quarter 2009. These increases were partially offset by lower interest income due to lower interest rates.

Income Taxes were $67 million in fourth quarter 2009 compared to $95 million for the same period in 2008. The decrease was primarily due to positive income tax adjustments in 2009, including a $30 million favourable adjustment resulting from a reduction in the Province of Ontario’s corporate income tax rates, partially offset by higher pre-tax income.

Non-Controlling Interests were $25 million for fourth quarter 2009 compared to $24 million for the same period in 2008.
