Additional information relating to TransCanada, including the Company's Annual Information Form and other continuous disclosure documents, is available on SEDAR at www.sedar.com under TransCanada Corporation. Unless otherwise indicated, "TransCanada" or "the Company" includes TransCanada Corporation and its subsidiaries. Amounts are stated in Canadian dollars unless otherwise indicated.  Capitalized and abbreviated terms that are used but not otherwise defined herein are identified in the Glossary of Terms contained in TransCanada’s 2008 Annual Report.

Forward-Looking Information

This MD&A may contain certain information that is forward looking and is subject to important risks and uncertainties. The words "anticipate", "expect", "believe", "may", "should", "estimate", "project", "outlook", "forecast" or other similar words are used to identify such forward-looking information. Forward-looking statements in this document are intended to provide TransCanada shareholders and potential investors with information regarding TransCanada and its subsidiaries, including management’s assessment of future financial and operational plans and outlook.  Forward-looking statements in this document may include, among others, statements regarding the anticipated business prospects and financial performance of TransCanada and its subsidiaries, expectations or projections about the future, strategies and goals for growth and expansion, expected and future cash flows, costs, schedules, operating and financial results and expected impact of future commitments and contingent liabilities.All forward-looking statements reflect TransCanada’s beliefs and assumptions based on information available at the time the statements were made. Actual results or events may differ from those predicted in these forward-looking statements. Factors that could cause actual results or events to differ materially from current expectations include, among others, the ability of TransCanada to successfully implement its strategic initiatives and whether such strategic initiatives will yield the expected benefits, the operating performance of the Company’s pipeline and energy assets, the availability and price of energy commodities, capacity payments, regulatory processes and decisions, changes in environmental and other laws and regulations, competitive factors in the pipeline and energy sectors, construction and completion of capital projects, labour, equipment and material costs, access to capital markets, interest and currency exchange rates, technological developments and the current economic conditions in North America.

SECOND QUARTER REPORT 2009

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 MD&A. 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.

Management uses the measures of comparable earnings, EBITDA and EBIT to better evaluate trends in the Company’s underlying operations. Comparable earnings, comparable EBITDA and comparable EBIT comprise net income, 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 MD&A presents a reconciliation of comparable earnings, comparable EBITDA, comparable EBIT and EBIT to Net Income. Comparable earnings per share is calculated by dividing comparable earnings by the weighted average number of shares outstanding for the period.

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.

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 "Liquidity and Capital Resources" section of this MD&A.

Financial Information Presentation

Effective January 1, 2009, TransCanada revised the information presented in the tables of this MD&A to better reflect the operating and financing structure of the Company. The Pipelines and Energy results summaries are presented geographically by separating the Canadian and U.S. portions of each segment. The Company believes this new format more clearly describes the financial performance of its business units. The new format presents EBITDA and EBIT as the Company believes these measures provide increased transparency and more useful information with respect to the performance of the Company’s individual assets. Segmented information has been retroactively reclassified to reflect these changes. These changes had no impact on reported consolidated Net Income.

TransCanada’s net income in second quarter 2009 was $314 million or $0.50 per share compared to $324 million or $0.58 per share in second quarter 2008. The decrease in net income reflects:

• increased EBIT from Pipelines, primarily due to the positive impact of a stronger U.S. dollar on Pipelines’ U.S. operations;

• decreased EBIT from Energy primarily due to lower power prices in Western Power and a $13 million year-over-year change in the after tax fair value adjustment of natural gas inventory and forward contracts. These decreases were partially offset by increased earnings in Bruce Power due to higher realized prices and in Eastern Power from the start up of Portlands Energy and the Carleton wind farm, and in the Natural Gas Storage business due to a lower cost of proprietary natural gas sold;

• increased EBIT losses from Corporate due to higher support services costs as a result of a growing asset base; and

TRANSCANADA [5

SECOND QUARTER REPORT 2009

• increased interest expense due to debt issuances throughout 2008 and first quarter 2009 offset by decreased income tax expense primarily due to reduced earnings and positive income tax adjustments in 2009.

Earnings per share in second quarter 2009 was further reduced primarily due to an 11 per cent increase in the average number of shares outstanding following the Company’s share issuances 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.

Comparable earnings in second quarter 2009 were $319 million or $0.51 per share compared to $316 million or $0.57 per share for the same period in 2008. Comparable earnings in second quarter 2009 and 2008 excluded $5 million of after tax unrealized losses ($7 million pre-tax) and $8 million of after tax unrealized gains ($12 million pre-tax), respectively, resulting from changes in the fair value of proprietary natural gas inventory and natural gas forward purchase and sale contracts.

Comparable EBIT was $672 million in second quarter 2009 compared to $633 million in second quarter 2008. The increase in comparable EBIT of $39 million was primarily due to increases in Pipelines and Energy, partially offset by increased support services costs in Corporate.

TransCanada’s net income in the first six months of 2009 was $648 million or $1.04 per share compared to $773 million or $1.40 per share for the same period in 2008. The $125 million decrease in net income reflects:

• decreased EBIT from Pipelines due to $152 million of after tax gains ($279 million pre-tax) on the sale of shares received by GTN and Portland for Calpine bankruptcy settlements and proceeds from a GTN lawsuit settlement of $10 million after tax ($17 million pre-tax) received in first quarter 2008. The impact of these items on the Pipelines segment was partially offset by the positive impact of a stronger U.S. dollar on Pipelines’ U.S. operations.

• increased EBIT from Energy due to increased contribution from Bruce Power as a result of higher realized prices and output, Eastern Power from the start up of Portlands Energy and the Carleton wind farm, and the impact of a $27 million after tax ($41 million pre-tax) writedown of costs capitalized for the Broadwater liquefied natural gas (LNG) project in first quarter 2008. These positive impacts in Energy were partially offset by decreased contributions from Western Power due to lower overall realized prices and lower volumes of power sold.

• increased EBIT losses from Corporate due to higher support services costs as a result of a growing asset base; and

• increased interest expense due to debt issuances throughout 2008 and first quarter 2009, and the negative impact of a stronger U.S. dollar, partially offset by decreased income tax expense due to lower earnings and positive income tax adjustments in 2009.

Earnings per share in the first six months of 2009 was further reduced due to an increased average number of shares outstanding following the Company’s share issuances in second quarter 2009, fourth quarter 2008 and second quarter 2008.

Comparable earnings in the first six months of 2009 were $662 million or $1.06 per share compared to $642 million or $1.17 per share for the same period in 2008. Comparable earnings for the first six months of 2009 and 2008 excluded $14 million after tax ($20 million pre-tax) and $4 million after tax ($5 million pre-tax), respectively, of net unrealized losses resulting from changes in the fair value of proprietary natural gas inventory and natural gas forward purchase and sale contracts. In addition, comparable earnings in the first six months of 2008 excluded the $152 million after tax gain on Calpine bankruptcy settlements, the $10 million after tax gain on the GTN lawsuit settlement and the $27 million after tax writedown of Broadwater LNG project costs.

TRANSCANADA [6

SECOND QUARTER REPORT 2009

Comparable EBIT was $1.5 billion in the first six months of 2009 compared to $1.4 billion in 2008. The increase in comparable EBIT of $67 million was primarily due to an increase in Pipelines’ comparable EBIT, partially offset by a decrease in Energy’s comparable EBIT and increased support services costs in Corporate.

Results from each of the segments for the three and six month periods ended June 30, 2009 are discussed further in the Pipelines, Energy and Corporate sections of this MD&A.

Pipelines

The Pipelines business generated comparable EBIT of $489 million and $1.1 billion in the three and six month periods ended June 30, 2009, respectively, compared to $457 million and $1.0 billion for the same periods in 2008.

Comparable EBIT for first six months of 2008 excluded the $279 million of gains realized by GTN and Portland for the Calpine bankruptcy settlements and the $17 million of proceeds received by GTN from a lawsuit settlement with a software supplier.

Canadian Pipelines

Canadian Mainline’s net income for the three and six months ended June 30, 2009 decreased $3 million and $5 million, respectively, primarily as a result of 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 operations, maintenance and administrative (OM&A) cost savings.

The Alberta System’s net income was $40 million in second quarter 2009 and $79 million for the first six months of 2009 compared to $33 million and $65 million for the same periods in 2008. Earnings in 2009 reflect the impact of a higher average investment base compared to 2008 due to customer-driven expansion of this system, and the impact of a 2008-2009 settlement approved by the Alberta Utilities Commission (AUC) in December 2008.

The Alberta System's EBITDA was $177 million in second quarter 2009 and $345 million for the first six months of 2009 compared to $179 million and $358 million for the same periods in 2008. These decreases were primarily due to lower revenues as a result of lower depreciation approved in the settlement, partially offset by revenue received for higher financial charges and increased earnings from the settlement.

U.S. Pipelines

ANR’s EBITDA in the three and six months ended June 30, 2009 was $73 million and $206 million, respectively, compared to $72 million and $174 million in the same periods in 2008. The increase in second quarter and the first six months in 2009 was primarily due to a stronger U.S. dollar in 2009, partially offset by reduced incidental natural gas and condensate sales primarily due to lower prices, and higher OM&A costs. For the six months ended June 30, 2009, the increase was also due to higher transportation and storage revenues as a result of increased utilization and favourable pricing on existing capacity and new growth projects.

GTN’s EBITDA for the three and six months ended June 30, 2009 was $49 million and $110 million, respectively, an increase of $3 million and $12 million, respectively, from the same periods in 2008. The increases were primarily due to a stronger U.S. dollar in 2009, partially offset by lower revenues.

EBITDA for the remainder of the U.S. Pipelines was $122 million and $302 million for the three and six months ended June 30, 2009, respectively, compared to $104 million and $245 million for the same periods in 2008. The increase was primarily due to a stronger U.S. dollar, increased short-term revenues for Iroquois and lower support costs in 2009.

(3) ANR’s and the GTN System’s results are not impacted by average investment base as these systems operate under fixed rate models approved by the U.S. Federal Energy Regulatory Commission.

Capitalized Project Costs

At June 30, 2009, Other Assets included $162 million of capitalized costs related to the Keystone pipeline system expansion to the U.S. Gulf Coast.

As at June 30, 2009, TransCanada had advanced $142 million to the Aboriginal Pipeline Group (APG) with respect to the Mackenzie Gas Pipeline Project (MGP). TransCanada and the other co-venture companies involved in the 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. Project timing continues to be uncertain and discussions between the co-venture group and the Canadian government are ongoing. In the event the co-venture group is unable to reach an agreement with the government on an acceptable fiscal framework, the parties will need to determine the appropriate next steps for the project. For TransCanada, this may result in a reassessment of the carrying amount of the APG advances.

Energy

Energy’s comparable EBIT was $214 million in second quarter 2009 compared to $202 million in second quarter 2008. Comparable EBIT excluded a net unrealized loss of $7 million and an unrealized gain of $12 million in second quarter 2009 and 2008, respectively, resulting from changes in the fair value of proprietary natural gas inventory and natural gas forward purchase and sale contracts.

Energy’s comparable EBIT was $418 million for the first six months of 2009 compared to $433 million in same six months of 2008. Comparable EBIT excluded net unrealized losses of $20 million and $5 million in 2009 and 2008, respectively, resulting from changes in the fair value of proprietary natural gas inventory and natural gas forward purchase and sale contracts. In addition, comparable EBIT in 2008 excluded the $41 million writedown of costs previously capitalized for the Broadwater LNG project.

(2) Excludes facilities that provide power to TransCanada under PPAs.

(3) Western Power plant availability increased in the three and six months ended June 30, 2009 due to outages at the MacKay River and Cancarb power facilities in 2008.

Western Power’s EBITDA of $59 million in second quarter 2009 decreased $79 million compared to $138 million in second quarter 2008. The decrease was primarily due to lower earnings from the Alberta power portfolio resulting from lower overall realized power prices.

Western Power’s EBITDA of $152 million in the first six months ended June 30, 2009 decreased $85 million compared to $237 million in the same period in 2008 primarily due to lower overall realized power prices on lower volumes of power sold, partially offset by lower power purchase arrangements (PPA) costs per megawatt hour (MWh).

Lower overall realized power prices resulted in decreases of $109 million and $189 million in Western Power’s power revenues for the three and six months ended June 30, 2009, respectively, compared to the same periods in 2008.

Eastern Power’s EBITDA of $60 million and $112 million for the three and six months ended June 30, 2009, respectively, increased $26 million and $43 million, respectively, compared to the same periods in 2008. These increases were primarily due to incremental earnings from Portlands Energy and the Carleton wind farm at Cartier Wind, which went into service in April 2009 and November 2008, respectively, as well as higher contracted revenue from Bécancour.

Plant Operating Costs and Other, which includes fuel gas consumed in generation, of $43 million and $87 million for the three and six months ended June 30, 2009, respectively, decreased from the same periods in 2008 primarily due to lower natural gas prices in Western Power.

Western Power manages the sale of its supply volumes on a portfolio basis. A portion of its supply is held for sale in the spot market for operational reasons and the amount of supply volumes eventually sold into the spot market is dependent upon the ability to transact in forward sales markets at acceptable contract terms. This approach to portfolio management assists in minimizing costs in situations where Western Power would otherwise have to purchase electricity in the open market to fulfill its contractual sales obligations. Approximately 76 per cent of Western Power sales volumes were sold under contract in second quarter 2009, compared to 80 per cent in second quarter 2008. To reduce its exposure to spot market prices on uncontracted volumes, as at June 30, 2009, Western Power has entered into fixed-price power sales contracts to sell approximately 4,800 gigawatt hours (GWh) for the remainder of 2009 and 6,100 GWh for 2010.

TRANSCANADA [11

SECOND QUARTER REPORT 2009

Eastern Power is focused on selling power under long-term contracts. As a result, in second 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 the remainder of 2009 and 2010.

TRANSCANADA [12

SECOND QUARTER REPORT 2009

TransCanada’s proportionate share of Bruce Power’s comparable EBITDA increased $53 million to $102 million in second quarter 2009 compared to second quarter 2008 primarily due to higher realized prices as well as increased output and lower operating costs as a result of fewer outage days.

TransCanada’s proportionate share of Bruce A’s comparable EBITDA increased $25 million to $47 million in second quarter 2009 compared to second quarter 2008 as a result of increased volumes and lower operating costs due to a decrease in outage days following the rescheduling of two planned outages from March 2009 to September 2009.  Bruce A’s availability in second quarter 2009 was 100 per cent as a result of having no outage days compared to an availability of 85 per cent and 27 outage days in the same period in 2008.

TransCanada’s proportionate share of Bruce B’s comparable EBITDA increased $28 million to $55 million in second quarter 2009 compared to second 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). This was partially offset by lower output due to 13 day increase in total outage days compared to second quarter 2008.

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 average floor price. Amounts received under the floor price mechanism in any year are subject to repayment if spot prices in the remainder of that year increase above the floor price.  With respect to 2009, TransCanada currently expects spot prices to be less than the floor price for the remainder of the year, therefore, no amounts recorded in revenue in the first six months of 2009 are expected to be repaid.

TransCanada’s proportionate share of Bruce Power’s Comparable EBITDA increased $98 million to $201 million in the six months ended June 30, 2009 compared to the same period in 2008 as a result of higher realized prices as well as higher output and lower operating costs due to fewer outage days.

TransCanada’s share of Bruce Power’s generation in second quarter 2009 increased to 3,225 GWh compared to 3,134 GWh in second quarter 2008. The Bruce Power units ran at a combined average availability of 83 per cent in second quarter 2009, compared to 82 per cent in second quarter 2008. In mid-April 2009, an approximate eight week planned outage of Bruce B Unit 8 commenced. An approximate six week maintenance outage of Bruce A Unit 4 and an approximate one month outage of Bruce A Unit 3 were rescheduled from March 2009 to September 2009. The overall plant availability percentage in 2009 is currently expected to be in the low 90s for the four Bruce B units and the mid 80s for the two operating Bruce A units.

Pursuant to the terms of a contract with the OPA, all of the output from Bruce A in second 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 second quarter 2008. All output from the Bruce B Units 5 to 8 were subject to a floor price of $48.76 per MWh in second quarter 2009 and $47.66 per MWh in second quarter 2008. Both the Bruce A and Bruce B contract prices are adjusted annually for inflation on April 1.

At June 30, 2009, Bruce B had sold forward approximately 1,900 GWh and 2,700 GWh, representing TransCanada’s proportionate share, for the remainder of 2009 and the year 2010, respectively. To reduce its exposure to spot prices, Bruce B had entered into most of these fixed price contracts in 2006 to 2008 when the spot price exceeded the floor price.  Under these 'contracts for differences', Bruce B receives the difference between the contract price and spot price on output sold forward under contract.  As a result, Bruce B’s realized price of $70 per MWh and $63 per MWh in the three and six months ended June 30, 2009, respectively, reflects revenues recognized from both the floor price mechanism and contract sales, compared to $56 per MWh in the same periods in 2008 in which no revenues were recognized under the floor price mechanism.

SECOND QUARTER REPORT 2009

As at June 30, 2009, Bruce A had incurred $2.9 billion in costs for the refurbishment and restart of Units 1 and 2, and approximately $0.2 billion for the refurbishment of Units 3 and 4.

(1) Includes Ravenswood effective August 2008.

U.S. Power’s EBITDA for the three months ended June 30, 2009 was $65 million, an increase of $15 million from the same period in 2008. Second quarter 2009 results reflect EBITDA from the Ravenswood facility acquired in August 2008 and the positive impact of the stronger U.S. dollar in 2009, partially offset by lower realized power prices in the New England market. For the six months ended June 30, 2009, U.S. Power’s EBITDA of $95 million decreased $10 million from the same period in 2008, primarily due to decreased water flows from the TC Hydro generation assets in second quarter 2009 compared to the considerably higher than average levels experienced in 2008, and lower realized prices in the New England market, partially offset by a stronger U.S. dollar.

U.S. Power’s power revenues for the three and six months ended June 30, 2009 of $321 million and $661 million, respectively, increased from $215 million and $441 million for the same periods in 2008 due to incremental revenue from the August 2008 acquisition of Ravenswood and the positive impact of the stronger U.S. dollar.

TRANSCANADA [14

SECOND QUARTER REPORT 2009

Power Commodity Purchases Resold of $117 million and $272 million for the three and six months ended June 30, 2009, respectively, increased from $105 million and $239 million compared to the same periods in 2008 primarily due to the impact of the stronger U.S. dollar in 2009.

Other Revenues and Other Commodity Purchases Resold of $78 million and $56 million, respectively, decreased in second quarter 2009 compared to second quarter 2008 as a result of decreased natural gas prices, partially offset by an increase in the volume of natural gas sold and purchased, and a stronger U.S. dollar.  The decrease in Other Revenues was also partially offset by incremental revenues earned related to a steam generating facility at Ravenswood.

Other Revenue and Other Commodity Purchases Resold of $250 million and $187 million, respectively, increased $73 million and $25 million, respectively, in the first six months ended June 30, 2009 primarily due to higher volumes of natural gas sold and purchased, and the impact of a stronger U.S. dollar, partially offset by a decrease in natural gas prices. In addition, Other Revenues also increased as a result of incremental revenues earned related to the steam generating facility at Ravenswood.

Plant Operating Costs and Other, which includes fuel gas consumed in generation, of $150 million and $334 million for the three and six months ended June 30, 2009, respectively, increased from $49 million and $93 million compared to the same periods in 2008 due to the incremental costs from Ravenswood.

In the three and six months ended June 30, 2009, 29 per cent and 28 per cent, respectively, of power sales volumes were sold into the spot market, compared to three and four per cent for the same periods in 2008, as there were no power sales contracts in place for Ravenswood extending beyond 2008 at the time the facility was acquired. U.S. Power is focused on selling the majority of its power under contract to wholesale, commercial and industrial customers, while managing a portfolio of power supplies sourced from its own generation and wholesale power purchases. To reduce its exposure to spot market prices on uncontracted volumes, as at June 30, 2009, U.S. Power had entered into fixed-price power sales contracts to sell approximately 3,800 GWh for the remainder of 2009 and 8,100 GWh for 2010, although certain contracted volumes are dependent on customer usage levels. Actual amounts contracted in future periods will depend on market liquidity and other factors.

Natural Gas Storage

Natural Gas Storage’s comparable EBITDA for the three and six month periods ended June 30, 2009 was $34 million and $70 million, respectively, compared to $6 million and $73 million for the same periods in 2008. The $28 million increase in EBITDA in second quarter 2009 was primarily due to a lower cost of proprietary natural gas sold at the Edson facility as well as increased third party storage revenues. The $3 million decrease in EBITDA for the six months ended June 30, 2009 was due to lower withdrawal activity and reduced sales of proprietary natural gas at the Edson facility compared to the same period in 2008.

Comparable EBITDA excluded net unrealized losses of $7 million and $20 million in the three and six months ended June 30, 2009, respectively (2008 - $12 million gain and $5 million loss), resulting from changes in the fair value of proprietary natural gas inventory in storage and natural gas forward purchase and sale contracts. TransCanada manages its proprietary natural gas storage earnings by simultaneously entering into a forward purchase of natural gas for injection into storage and an offsetting forward sale of natural gas for withdrawal at a later period, thereby locking in future positive margins and effectively eliminating exposure to price movements of natural gas. Fair value adjustments are recorded in each period on proprietary natural gas held in storage and these forward contracts are not representative of the amounts that will be realized on settlement. Beginning in second quarter 2009, the fair value of proprietary natural gas inventory held in storage is measured using a weighted average of forward prices for the following four months less selling costs. Previously the inventory was measured using the one-month forward price.  The impact of this change on EBITDA for the three and six months ended June 30, 2009 was insignificant.

SECOND QUARTER REPORT 2009

Depreciation and Amortization

Depreciation and Amortization for the three and six months ended June 30, 2009 of $87 million and $173 million, respectively, increased $29 million and $59 million, respectively, compared with the same periods in 2008, primarily due to the acquisition of Ravenswood in August 2008.

Corporate

Corporate EBIT losses for the three and six months ended June 30, 2009 were $31 million and $61 million, respectively, compared to losses of $26 million and $48 million for the same periods in 2008. These decreases in Corporate EBIT were primarily due to higher support services costs in 2009, reflecting a growing asset base.

Interest Expense for second quarter 2009 increased $73 million to $259 million from $186 million in second quarter 2008. Interest Expense for the six months ended June 30, 2009, increased $150 million to $554 million from $404 million for the six months ended June 30, 2008. The increases were primarily due to new debt issues of US$1.5 billion and $500 million in August 2008, US$2.0 billion in January 2009 and $700 million in February 2009. In addition, U.S. dollar-denominated interest expense increased due to the impact of a stronger U.S. dollar. These increases were partially offset by increased capitalization of interest to finance the Company’s larger capital spending program in 2009.

On a consolidated basis, the positive impact of a stronger U.S. dollar on U.S. Pipelines and Energy EBIT is almost fully offset by the net negative impact on U.S. dollar interest expense and other income statement items, thereby effectively reducing the Company’s net exposure to changes in foreign exchange.

Interest Income and Other was $34 million and $56 million for the three and six month periods ended June 30, 2009, respectively, compared to $25 million and $36 million for the same periods in 2008. The increase of $9 million and $20 million for the three and six months ended June 30, 2009, respectively, was primarily due to higher gains from changes in the fair value of derivatives used to manage the Company’s exposure to foreign exchange rate fluctuations and the positive impact of a stronger U.S. dollar. Partially offsetting these increases was reduced interest income as a result of lower interest rates in 2009.

SECOND QUARTER REPORT 2009

Income Taxes were $97 million in second quarter 2009 compared to $126 million for the same period in 2008. Income Taxes for the six months ended June 30, 2009 were $213 million compared to $378 million for the same period in 2008. The decreases were primarily due to reduced earnings, higher income tax rate differentials and other positive income tax adjustments in 2009.

Non-Controlling Interests were $13 million for second quarter 2009 compared to $17 million for the same period in 2008. The decrease of $4 million was primarily due to lower earnings from PipeLines LP. Non-Controlling Interests of $48 million for the first six months of 2009, decreased $40 million compared to $88 million for the same period in 2008, primarily due to the non-controlling interests’ portion of Portland’s Calpine bankruptcy settlement in first quarter 2008.

Liquidity and Capital Resources

Global Market Conditions

Despite continued uncertainty in global financial markets, TransCanada’s financial position remains sound and consistent with recent years as does its ability to generate cash in the short and long term to provide liquidity, maintain financial capacity and flexibility, as well as provide for planned growth. TransCanada’s liquidity position remains solid, underpinned by highly predictable cash flow from operations, significant cash balances on hand from recent debt and equity issues, as well as committed revolving bank lines of US$1.0 billion, $2.0 billion and US$300 million, maturing in November 2010, December 2012 and February 2013, respectively. To date, no draws have been made on these facilities as TransCanada has maintained continuous access to the Canadian commercial paper market on competitive terms. An additional approximate $230 million of capacity remains available on Canadian and U.S. dollar committed bank facilities at TransCanada-operated affiliates with maturity dates from 2010 through 2012. In addition, common shares are expected to be issued under the Company’s Dividend Reinvestment and Share Purchase Plan (DRP) in lieu of making cash dividend payments.

At June 30, 2009, the Company held cash and cash equivalents of $3.5 billion compared to $1.3 billion at December 31, 2008. The increase in cash and cash equivalents was primarily due to proceeds from the issuance of common shares in second quarter 2009 and long-term debt in first quarter 2009.

Acquisitions, net of cash acquired, were $115 million in second quarter 2009 (2008 - $2 million) and $249 million (2008 - $4 million) for the six months ended June 30, 2009. The acquisitions included the increase in ownership interest in Keystone pursuant to an agreement with ConocoPhillips that closed in December 2008.

TransCanada remains committed to executing its previously announced $21 billion capital expenditure program over the next four years.  For the three and six months ended June 30, 2009, capital expenditures totalled $1.3 billion and $2.4 billion, respectively (2008 - $633 million and $1.1 billion), primarily related to the Keystone pipeline system, expansion of the Alberta System, refurbishment and restart of Bruce A Units 1 and 2, and construction of Kibby Wind, Halton Hills, Coolidge and Bison.

Financing Activities

On June 24, 2009, TransCanada completed a public offering of 50.8 million common shares.  On June 30, 2009, an additional 7.6 million common shares were issued upon exercise of an underwriters' over-allotment option.  Proceeds from the common share offering and the over-allotment option totalled $1.8 billion and will be used by TransCanada to partially fund capital projects of the Company, including the acquisition of the remaining interest in Keystone, for general corporate purposes and to repay short-term indebtedness. With this offering, the Company is well positioned to fund its existing capital program through its growing internally-generated cash flow, its DRP and the issuance of long-term debt, supplemented by further subordinated capital, as required, in the form of preferred shares or other hybrid securities. As demonstrated by the recent sale of North Baja, TransCanada will also continue to examine opportunities for portfolio management, including a greater role for PipeLines LP, in the financing of its capital program.

As a result of the June 2009 common share issue, TransCanada has effectively exhausted the $3.0 billion base equity shelf prospectus filed in July 2008. The Company expects to file a new base equity shelf prospectus in the normal course in third quarter 2009.

In the three and six months ended June 30, 2009, TransCanada issued nil and $3.1 billion, respectively, (2008 - nil and $112 million), and retired $18 million and $500 million, respectively (2008 - $379 million and $773 million), of long-term debt. TransCanada’s notes payable increased $233 million and decreased $684 million in the three and six months ended June 30, 2009, respectively, compared to increases of $754 million and $724 million for the same periods in 2008.

On April 23, 2009, TCPL filed a $2.0 billion Canadian Medium-Term Notes shelf prospectus to replace a March 2007 $1.5 billion Canadian Medium-Term Notes shelf prospectus, which expired in April 2009. No amounts have been issued under this shelf prospectus.

In February 2009, TCPL issued Medium-Term Notes of $300 million and $400 million maturing in February 2014 and February 2039, respectively, and bearing interest at 5.05 per cent and 8.05 per cent, respectively. These notes were issued under the $1.5 billion debt shelf prospectus filed in March 2007.

In January 2009, TCPL issued Senior Unsecured Notes of US$750 million and US$1.25 billion maturing in January 2019 and January 2039, respectively, and bearing interest at 7.125 per cent and 7.625 per cent, respectively. These notes were issued under a US$3.0 billion debt shelf prospectus filed in January 2009, which now has capacity of US$1.0 billion remaining.

SECOND QUARTER REPORT 2009

Dividends

On July 30, 2009, TransCanada's Board of Directors declared a quarterly dividend of $0.38 per share for the quarter ending September 30, 2009 on the Company’s outstanding common shares. It is payable on October 30, 2009 to shareholders of record at the close of business on September 30, 2009.

TransCanada’s Board of Directors also approved the issuance of common shares from treasury at a three per cent discount under TransCanada’s DRP for the dividends payable on October 30, 2009. The Company reserves the right to alter the discount or return to purchasing shares on the open market at any time. In the three and six months ended June 30, 2009, TransCanada issued 1.4 million and 3.5 million common shares, respectively, under its DRP, in lieu of making cash dividend payments of $42 million and $109 million, respectively.

Significant Accounting Policies and Critical Accounting Estimates

To prepare financial statements that conform with Canadian GAAP, TransCanada is required to make estimates and assumptions that affect both the amount and timing of recording assets, liabilities, revenues and expenses since the determination of these items may be dependent on future events. The Company uses the most current information available and exercises careful judgement in making these estimates and assumptions.

TransCanada's significant accounting policies and critical accounting estimates have remained unchanged since December 31, 2008. For further information on the Company’s accounting policies and estimates refer to the MD&A in TransCanada's 2008 Annual Report.

Changes in Accounting Policies

The Company’s accounting policies have not changed materially from those described in TransCanada’s 2008 Annual Report except as follows:

2009 Accounting Changes

Rate-Regulated Operations

Effective January 1, 2009, the temporary exemption was withdrawn from the Canadian Institute of Chartered Accountants (CICA) Handbook Section 1100 “Generally Accepted Accounting Principles”, which permitted the recognition and measurement of assets and liabilities arising from rate regulation. In addition, Section 3465 “Income Taxes” was amended to require the recognition of future income tax assets and liabilities for rate-regulated entities. The Company chose to adopt accounting policies consistent with the U.S. Financial Accounting Standards Board’s Financial Accounting Standard (FAS) 71 “Accounting for the Effects of Certain Types of Regulation”. As a result, TransCanada retained its current method of accounting for its rate-regulated operations, except that TransCanada is required to recognize future income tax assets and liabilities, instead of using the taxes payable method, and records an offsetting adjustment to regulatory assets and liabilities. As a result of adopting this accounting change, additional future income tax liabilities and a regulatory asset in the amount of $1.4 billion were recorded January 1, 2009 in each of Future Income Taxes and Other Assets, respectively.

Adjustments to the 2009 financial statements have been made in accordance with the transitional provisions for Section 3465, which required a cumulative adjustment in the current period to future income taxes and a regulatory asset. Restatement of prior periods’ financial statements was not permitted under Section 3465.

SECOND QUARTER REPORT 2009

Intangible Assets

Effective January 1, 2009, the Company adopted CICA Handbook Section 3064 “Goodwill and Intangible Assets“, which replaced Section 3062 “Goodwill and Other Intangible Assets”. Section 3064 gives guidance on the recognition of intangible assets as well as the recognition and measurement of internally developed intangible assets. In addition, Section 3450 “Research and Development Costs” was withdrawn from the Handbook. Adopting this accounting change did not have a material effect on the Company’s financial statements.

Credit Risk and the Fair Value of Financial Assets and Financial Liabilities

Effective January 1, 2009, the Company adopted the accounting provisions of Emerging Issues Committee (EIC) Abstract EIC 173, “Credit Risk and the Fair Value of Financial Assets and Financial Liabilities”. Under EIC 173 an entity’s own credit risk and the credit risk of its counterparties is taken into account in determining the fair value of financial assets and financial liabilities, including derivative instruments. Adopting this accounting change did not have a material effect on the Company’s financial statements.

Future Accounting Changes

International Financial Reporting Standards

The CICA’s Accounting Standards Board announced that Canadian publicly accountable enterprises are required to adopt International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (IASB), effective January 1, 2011. The Company will prepare its financial statements under IFRS commencing January 1, 2011.

TransCanada has developed a conversion plan that is overseen by its IFRS Implementation and Steering Committees. The plan includes identifying resources and training requirements, analyzing the impact of key differences between Canadian GAAP and IFRS, and developing a phased approach to conversion implementation. The Company’s conversion project is discussed in further detail in its 2008 Annual Report. TransCanada continues to progress its conversion project by scheduling training sessions and IFRS updates for employees, reviewing new IFRS developments and assessing the impact that significant differences between Canadian GAAP and IFRS may have on TransCanada.

Under existing Canadian GAAP, TransCanada follows specific accounting policies unique to a rate-regulated business. TransCanada is actively monitoring developments regarding potential future guidance on the applicability of certain aspects of rate-regulated accounting under IFRS. Developments in this area could have a significant effect on the scope of the Company's IFRS project and on TransCanada’s financial results under IFRS. On July 23, 2009, the IASB issued an exposure draft “Rate-regulated Activities” and the Company is assessing the impact of this exposure draft on TransCanada.

The impact of the adoption of IFRS on the Company’s consolidated financial statements and accounting systems is currently being evaluated. At the current stage of its IFRS project, TransCanada cannot reasonably determine the full impact that adopting IFRS would have on its financial position and future results.

Financial Instruments Disclosure

The CICA implemented revisions to Handbook Section 3862 “Financial Instruments – Disclosures” for fiscal years ending after September 30, 2009. These revisions are intended to align the disclosure requirements for financial instruments to the maximum extent possible with the disclosure required under IFRS. These revisions require additional disclosure based on a three level hierarchy that reflects the significance of inputs used in measuring fair value. Fair values of assets and liabilities included in Level 1 are determined by reference to quoted prices in active markets for identical assets and liabilities. Fair values of assets and liabilities included in Level 2 include valuations using inputs other than quoted prices for which all significant outputs are observable, either directly or indirectly. Fair values of assets and liabilities included in Level 3 valuations are based on inputs that are unobservable and significant to the overall fair value measurement. These changes will be applied by TransCanada effective December 31, 2009.

SECOND QUARTER REPORT 2009

Contractual Obligations

On June 16, 2009, the Company entered into an agreement to acquire ConocoPhillips’ remaining interest in Keystone for approximately US$550 million plus the assumption of approximately US$200 million of short-term indebtedness. The transaction is expected to close in third quarter 2009. In addition, TransCanada will also assume responsibility for ConocoPhillips’ share of the capital investment required to complete the project, which is expected to result in an incremental commitment of US$1.7 billion through the end of 2012.

Other than the commitments discussed above and obligations for future debt and interest payments relating to debt issuances and redemptions discussed in the “Financing Activities” section of this MD&A, there have been no other material changes to TransCanada’s contractual obligations from December 31, 2008 to June 30, 2009, including payments due for the next five years and thereafter. For further information on these contractual obligations, refer to the MD&A in TransCanada’s 2008 Annual Report.

Financial Instruments and Risk Management

TransCanada continues to manage and monitor its exposure to market, counterparty credit and liquidity risk.

Counterparty Credit and Liquidity Risk

TransCanada’s maximum counterparty credit exposure with respect to financial instruments at the balance sheet date, without taking into account security held, consisted primarily of the carrying amount, which approximates fair value, of non-derivative financial assets, such as accounts receivable, as well as the fair value of derivative assets. Letters of credit and cash are the primary types of security provided to support these amounts. The Company does not have significant concentrations of counterparty credit risk with any individual counterparties and the majority of counterparty credit exposure is with counterparties who are investment grade. At June 30, 2009, there were no significant amounts past due or impaired.

As the uncertainty in the global financial markets persists, TransCanada continues to closely monitor and reassess the creditworthiness of its counterparties. This has resulted in TransCanada reducing or mitigating its exposure to certain counterparties where it is deemed warranted and permitted under contractual terms. As part of its ongoing operations, TransCanada must balance its market and counterparty credit risks when making business decisions.

The Company continues to manage its liquidity risk by ensuring sufficient cash and credit facilities are available to meet its operating and capital expenditure obligations when due, under both normal and stressed economic conditions. Further discussion of the Company’s ability to manage its cash and credit facilities is provided in the “Liquidity and Capital Resources” section in this MD&A.

Natural Gas Inventory

At June 30, 2009, the fair value of proprietary natural gas inventory held in storage as measured using a weighted average of forward prices for the following four months less selling costs was $44 million (December 31, 2008 - $76 million). Prior to second quarter 2009, inventory was measured using the one-month forward price. The impact of this change was insignificant.

TRANSCANADA [21

SECOND QUARTER REPORT 2009

The change in fair value of proprietary natural gas inventory in the three and six months ended June 30, 2009 resulted in pre-tax net unrealized losses of $6 million and $29 million, respectively, which were recorded as a decrease to Revenues and Inventories (gains of $42 million and $102 million for the three and six months ended June 30, 2008). The net change in fair value of natural gas forward purchase and sales contracts in the three and six months ended June 30, 2009 resulted in a pre-tax net unrealized loss of $1 million and a pre-tax net unrealized gain of $9 million (losses of $30 million and $107 million for the three and six months ended June 30, 2008), respectively, which were included in Revenues.

Net Investment in Self-Sustaining Foreign Operations

The Company hedges its net investment in self-sustaining foreign operations with U.S. dollar-denominated debt, cross-currency swaps and foreign exchange forward contracts and options. At June 30, 2009, the Company had designated as a net investment hedge U.S. dollar-denominated debt with a carrying value of $8.8 billion (US$7.6 billion) and a fair value of $9.2 billion (US$7.9 billion). At June 30, 2009, Deferred Amounts included $124 million for the fair value of derivatives used to hedge the Company’s net U.S. dollar investment in foreign operations.

Information for the derivatives used to hedge the Company’s net investment in its self-sustaining foreign operations is as follows:

Other Risks

Additional risks faced by the Company are discussed in the MD&A in TransCanada’s 2008 Annual Report. These risks remain substantially unchanged since December 31, 2008.

Controls and Procedures

As of June 30, 2009, an evaluation was carried out under the supervision of, and with the participation of management, including the President and Chief Executive Officer and the Chief Financial Officer, of the effectiveness of TransCanada’s disclosure controls and procedures as defined under the rules adopted by the Canadian securities regulatory authorities and by the SEC. Based on this evaluation, the President and Chief Executive Officer and the Chief Financial Officer concluded that the design and operation of TransCanada’s disclosure controls and procedures were effective as at June 30, 2009.

During the recent fiscal quarter, there have been no changes in TransCanada’s internal control over financial reporting that have materially affected, or are reasonably likely to materially affect, TransCanada’s internal control over financial reporting.

During second quarter 2009, TransCanada completed its integration of Ravenswood’s internal controls over financial reporting.

SECOND QUARTER REPORT 2009

Outlook

The economic turmoil and deterioration of financial markets in North America is continuing to have a slowing effect on certain aspects of the North American economy. TransCanada does not expect this to have a material effect on the Company’s financial position, access to capital markets, committed projects or corporate strategy.

Since the disclosure in TransCanada’s 2008 Annual Report, the Company's earnings outlook for 2009 has declined due to the negative impact of reduced market prices for power on Energy’s results. With respect to the Pipelines segment, although the global economic downturn has an impact on throughput on certain pipelines and on some drilling activities, the short-term financial outlook for the Company’s Pipelines segment is not expected to be materially impacted as the pipeline assets are generally underpinned by contracts or earn a regulated rate of return.

TransCanada completed the issuance of $1.8 billion of common shares in second quarter 2009, $3.1 billion of long-term debt in first quarter 2009 and $1.1 billion of common shares at the end of 2008. While these offerings will impact future net income and earnings per share through carrying costs and dilution, when combined with $1.9 billion of cash provided by operations in the first half of 2009, they have contributed to a cash balance of $3.5 billion at June 30, 2009 and provided most of the necessary financing for the Company’s 2009 capital expenditure program and acquisition of the remaining interest in Keystone. This strategy of strengthening TransCanada’s liquidity and financial position through its ability to successfully access capital markets in very volatile and uncertain economic times has reduced the Company’s future financing risk around its committed growth program.  For further information on outlook, refer to the MD&A in TransCanada’s 2008 Annual Report.

Since December 31, 2008, there have been no changes to TransCanada’s credit ratings. TransCanada’s issuer rating assigned by Moody’s Investors Service (Moody’s) is Baa1 with a stable outlook. TransCanada PipeLines Limited’s senior unsecured debt is rated A with a stable outlook by DBRS, A3 with a stable outlook by Moody’s and A- with a stable outlook by Standard and Poor’s.

Recent Developments

Pipelines

Keystone

On June 16, 2009, TransCanada announced an agreement to acquire ConocoPhillips’ remaining interest in Keystone for approximately US$550 million plus the assumption of approximately US$200 million of short-term indebtedness. The purchase price reflects ConocoPhillips’ capital contributions to date and includes an allowance for funds used during construction. TransCanada will also assume responsibility for ConocoPhillips’ share of the capital investment required to complete the project, resulting in an incremental commitment of approximately US$1.7 billion through the end of 2012. The transaction is expected to close in third quarter 2009, subject to the receipt of certain regulatory approvals. At June 30, 2009, TransCanada’s equity ownership in the Keystone partnerships was 77 per cent.

The first phase of Keystone is currently under construction. It will extend 3,456 km (2,148 miles) from Hardisty, Alberta to serve markets in Wood River and Patoka, Illinois, and have an initial nominal capacity of 435,000 barrels per day (bbl/d). Commissioning of this segment is expected to commence in late 2009 with commercial operations to follow in early 2010. At July 30, 2009, the first phase was approximately 80 per cent complete. The pipeline is expected to subsequently be expanded to a nominal capacity of 590,000 bbl/d and extend to Cushing, Oklahoma. Commissioning of the Cushing segment is expected to commence in late 2010.

SECOND QUARTER REPORT 2009

Keystone is also currently seeking the necessary regulatory approvals in Canada and the U.S. to construct and operate an expansion and extension of the pipeline that will provide additional capacity of 500,000 bbl/d from Western Canada to the U.S. Gulf Coast in 2012. This Keystone expansion will extend 2,720 km (1,690 miles) from Hardisty, Alberta to a delivery point near existing terminals in Port Arthur, Texas. Construction of the expansion facilities is anticipated to commence in 2010 following the receipt of the necessary regulatory approvals.

The total capital cost of Keystone is expected to be approximately US$12 billion. Approximately US$3 billion has been spent to date with the remaining approximately US$9 billion expected to be incurred by the end of 2012. Capital costs related to the construction of Keystone are subject to capital cost risk-and-reward sharing mechanisms with its customers.

Keystone is expected to begin generating EBITDA in first quarter 2010 when commercial operations to Wood River and Patoka, Illinois commence, with EBITDA increasing through 2011 and 2012 as subsequent phases are placed in service. Based on current long-term commitments of 910,000 bbl/d, Keystone is expected to generate EBITDA of approximately US$1.2 billion in 2013, its first full year of commercial operation serving both the U.S. Midwest and Gulf Coast markets. If volumes increase to 1.1 million bbl/d, the full commercial design of the system, Keystone would generate approximately US$1.5 billion of annual EBITDA. In the future, Keystone can be economically expanded from 1.1 million bbl/d to 1.5 million bbl/d in response to additional market demand.

Alaska

On June 11, 2009, TransCanada and ExxonMobil Corporation reached an agreement to work together to progress TransCanada’s Alaska pipeline project. With a forecasted capital cost of US$26 billion (2007 estimate in 2007 dollars), the project would provide a variety of benefits to Alaska and Canada, as well as the rest of the U.S., including substantial revenues, jobs, business opportunities and new, long-term stable supplies of natural gas.

The Alaska pipeline project continues to move forward with project development, including engineering, environmental reviews, Alaska Native and Canadian Aboriginal engagement, and commercial work to conclude an initial binding open season by July 2010. Subject to the completion of a successful open season, construction of the approximately 2,700 km (1,700 miles), 4.5 Bcf per day pipeline would begin in 2016, once environmental and regulatory approvals are received, and the pipeline would begin transporting natural gas in 2018.

North Baja

On July 1, 2009, TransCanada sold the North Baja pipeline to PipeLines LP. As part of the transaction, TransCanada agreed to amend its incentive distribution rights with PipeLines LP. TransCanada received aggregate consideration totalling approximately US$395 million from PipeLines LP, including approximately US$200 million in cash and 6,371,680 common units of PipeLines LP. PipeLines LP utilized US$170 million of its US$250 million committed and available bank facility to fund this transaction.  TransCanada’s ownership in PipeLines LP increased to 42.6 per cent as a result of this transaction. The Company will continue to operate the North Baja pipeline.

Alberta System

The Company has initiated discussions with stakeholders to transfer the Alberta System’s 2008 – 2009 Revenue Requirement Settlement to NEB jurisdiction. Following these discussions, TransCanada will apply to the NEB for approval of final 2009 tolls.

In April 2009, TransCanada submitted an application to the NEB for approval to construct and operate the Groundbirch pipeline, which comprises a 77 km (48 miles) natural gas pipeline and related facilities including meter stations and valve sites. The Groundbirch pipeline is an extension of the Alberta System which is expected to connect natural gas supply primarily from the Montney shale gas region in northeast B.C. to existing infrastructure in northwest Alberta. In June 2009, the NEB announced that it will hold a public hearing process on the application. The oral part of the hearing is scheduled to begin November 17, 2009. Subject to regulatory approvals, construction of the Groundbirch pipeline is expected to commence in July 2010 with final completion anticipated in November 2010.

In May 2009, TransCanada filed a Project Description with the NEB to construct the Horn River natural gas pipeline. The Horn River pipeline is a proposed extension of the Alberta System to service the Horn River shale gas region in northeast B.C. Horn River producers have recently notified TransCanada that they are extending their construction schedule for upstream production facilities which will enhance their ability to manage project costs.  Therefore, TransCanada will delay the in-service date of the Horn River pipeline from 2011 to 2012.

Guadalajara

In May 2009, TransCanada entered into a contract to build, own and operate a US$320 million pipeline in Mexico, which is supported by a 25-year contract for its entire capacity with Comisión Federal de Electricidad, Mexico’s state-owned electric company.

The proposed Guadalajara pipeline will extend 310 km (193 miles) from an LNG terminal under construction near Manzanillo, Mexico, to Guadalajara and is expected to be capable of transporting 500 million cubic feet per day of natural gas. The Company expects to complete most of the construction in 2010 with a targeted in-service date of March 2011.

TQM

In June 2009, the NEB approved TQM’s final tolls for 2007 and 2008, consisting of a 6.4 per cent after-tax weighted average cost of capital on its cost of capital application for the years 2007 and 2008.  This decision equates to a 9.85 per cent return on 40 per cent deemed common equity in 2007 and a 9.75 per cent return on 40 per cent deemed common equity in 2008. The decision granted TQM an aggregate return on capital, leaving it to TQM to choose its optimal capital structure. TQM expects to recover the variance between interim and final tolls for 2007 and 2008 in third quarter 2009. The net earnings impact related to the variance was recorded by TQM in first quarter 2009.

Ventures LP

In May 2009, the AUC announced that it intends to seek an Order in Council allowing it to set rates on the Ventures LP pipeline. Ventures LP has initiated appeal proceedings of this decision and the application to the court is expected to commence in third quarter 2009.

Bison

The Bison pipeline project is expected to be in service November 2010.  The regulatory approval process and the engineering and procurement work are progressing as planned.

Review of NEB ROE Formula

In May 2009, the NEB received comments on whether it should initiate a multi-pipeline review of the RH-2-94 Decision pursuant to the National Energy Board Act (Canada) (NEB Act), which established an ROE formula tied to 10 year and 30 year Government of Canada bond rates, that has formed the basis of determining tolls for pipelines under NEB jurisdiction since January 1, 1995. Based on comments submitted, the NEB has decided to initiate a review of this decision by seeking comments on the continuing applicability of the decision by September 18, 2009. TransCanada’s position, included in its May 2009 letter to the NEB, is that the decision should be rescinded on a prospective basis.

Land Matters Consultation Initiative

In May 2009, the NEB issued its RH-2-2008 Decision on the Land Matters Consultation Initiative Stream 3 with respect to financial issues related to pipeline abandonment. All pipeline companies regulated under the NEB Act will be required to comply with the framework and action plan set out in the decision. The NEB’s goal is to have pipeline companies begin collecting and setting aside funds to cover future abandonment costs no later than mid-2014. There are several filing deadlines in the action plan with which NEB regulated pipeline companies have to comply, including deadlines for the preparation and filing of an estimate of the abandonment costs, developing a proposal for collection of funds through tolls or some other satisfactory method and developing a proposed process to set aside the funds collected. As a result of this decision, TransCanada has initiated a project to estimate the abandonment costs on its NEB regulated pipelines to be filed with the NEB for approval by May 31, 2011.

Energy

Bruce Power

On July 6, 2009, Bruce Power and the OPA amended certain terms and conditions of commercial agreements in place between the two parties.

Payments received pursuant to the Bruce B floor price mechanism were previously subject to repayment during the entire term of the contract, dependent on future periods’ spot prices. The contract with the OPA was amended such that, beginning in 2009, annual payments received will not be subject to repayment in future years.

Other changes to the contract with the OPA include the removal of a support payment cap for Bruce A. The cumulative support payments received by Bruce A, which are equal to the difference between the fixed prices under the OPA contract and spot market prices, were originally capped at $575 million until both Units 1 and 2 were restarted. Under the amendment, should either of the restarted Units 1 and 2 not be placed into commercial service by December 31, 2011, Bruce A will receive spot prices on all of its output until the restart of both units is complete, after which Bruce A prices will return to the then prevailing contract levels.

The OPA contract was also amended, commencing July 6, 2009, to provide for deemed generation payments to Bruce Power at contract prices under circumstances when Bruce Power generation is reduced due to system curtailments on the Independent Electricity System Operator controlled grid in Ontario.

TRANSCANADA [30

SECOND QUARTER REPORT 2009

Additionally, the capital cost sharing mechanism for the restart and refurbishment of Bruce A Units 1 and 2 was amended such that the OPA will not share in any cost overruns over $3.4 billion. Previously the OPA was responsible for 25 per cent of cost overruns above $3.4 billion through a future adjustment to the fixed price paid to Bruce Power for power generated by the Bruce A units. Although Bruce Power estimates the total capital costs to be $3.4 billion, the Company’s current view is that costs may exceed that amount by up to ten per cent. Units 1 and 2 are expected to return to service by the end of 2010.

Cartier Wind

On June 10, 2009, the Government of Québec approved the construction of the 212 MW Gros-Morne and 58 MW Montagne-Sèche wind farms.  Both wind farms are expected to be operational by 2012, representing an investment of approximately $340 million. These are the fourth and fifth Québec -based wind farms either in place or under development by Cartier Wind, which is 62 per cent owned by TransCanada.

Kibby Wind

TransCanada continues to advance construction on the Kibby Wind power project, including the installation of 22 turbines which are expected to be completed in the summer of 2009. Kibby Wind is expected to have the capacity to produce 132 MW of power when complete, with commissioning of the first phase of the project to begin in late 2009.

Coolidge

TransCanada expects to begin construction of the US$500 million Coolidge generating station in August 2009. The 575 MW, simple-cycle, natural gas-fired peaking power facility is expected to be in service in second quarter 2011.

Bécancour

On June 29, 2009, TransCanada entered into an agreement with Hydro-Québec to continue to suspend all electricity generation from the Bécancour power plant throughout 2010. Hydro-Québec has the option, subject to certain conditions, to extend the suspension on an annual basis until such time as regional electricity demand levels recover. TransCanada will continue to receive payments under the agreement similar to those that would have been received under the normal course of operation.

Ravenswood

Ravenswood’s 972 MW Unit 30 returned to service May 17, 2009 following an extensive outage.  The Company continues to work with its insurers with respect to claims for both the physical damage and business interruption losses associated with the outage.

In 2010, the Company expects capacity prices in the New York City Zone J, in which Ravenswood operates, to return to historic levels, which were somewhat higher than current rates. This increase in capacity prices will be driven in part by the long-planned retirement of a power generating facility owned by the New York Power Authority, which is scheduled to occur in January 2010.

Factors Impacting Quarterly Financial Information

In Pipelines, which consists primarily of the Company's investments in regulated pipelines and regulated natural gas storage facilities, annual revenues and net income fluctuate over the long term based on regulators' decisions and negotiated settlements with shippers. Generally, quarter-over-quarter revenues and net income during any particular fiscal year remain relatively stable with fluctuations resulting from adjustments being recorded due to regulatory decisions and negotiated settlements with shippers, seasonal fluctuations in short-term throughput volumes on U.S. pipelines, acquisitions and divestitures, and developments outside of the normal course of operations.

In Energy, which consists primarily of the Company’s investments in electrical power generation plants and non-regulated natural gas storage facilities, quarter-over-quarter revenues and net income are affected by seasonal weather conditions, customer demand, market prices, planned and unplanned plant outages, acquisitions and divestitures, certain fair value adjustments and developments outside of the normal course of operations.

Significant developments that impacted the last eight quarters' EBIT and Net Income are as follows:

• Second quarter 2009, Energy’s EBIT included net unrealized losses of $7 million pre-tax ($5 million after tax) due to changes in the fair value of proprietary natural gas storage inventory and natural gas forward purchase and sale contracts. Energy’s EBIT also included contributions from Portlands Energy, which was placed in service in April 2009.

• First quarter 2009, Energy’s EBIT included net unrealized losses of $13 million pre-tax ($9 million after tax) due to changes in the fair value of proprietary natural gas storage inventory and natural gas forward purchase and sale contracts.

• Fourth quarter 2008, Energy’s EBIT included net unrealized gains of $7 million pre-tax ($6 million after tax) due to changes in the fair value of proprietary natural gas storage inventory and natural gas forward purchase and sale contracts. Corporate’s EBIT included net unrealized losses of $57 million pre-tax ($39 million after tax) for changes in the fair value of derivatives used to manage the Company’s exposure to rising interest rates but which do not qualify as hedges for accounting purposes.

TRANSCANADA [32

SECOND QUARTER REPORT 2009

• Third quarter 2008, Energy’s EBIT included contributions from the August 26, 2008 acquisition of Ravenswood. Net Income included favourable income tax adjustments of $26 million from an internal restructuring and realization of losses.

• First quarter 2008, Pipelines’ EBIT included $279 million pre-tax ($152 million after tax) from the Calpine bankruptcy settlements received by GTN and Portland, and proceeds of $17 million pre-tax ($10 million after tax) from a lawsuit settlement. Energy’s EBIT included a writedown of $41 million pre-tax ($27 million after tax) of costs related to the Broadwater LNG project and net unrealized losses of $17 million pre-tax ($12 million after tax) due to changes in the fair value of proprietary natural gas storage inventory and natural gas forward purchase and sale contracts.

• Fourth quarter 2007, Net Income included $56 million of favourable income tax adjustments resulting from reductions in Canadian federal income tax rates and other legislative changes. Energy’s EBIT increased due to a $16 million pre-tax ($14 million after tax) gain on sale of land previously held for development. Pipelines’ EBIT increased as a result of recording incremental earnings related to a rate case settlement reached for the GTN System, effective January 1, 2007. Energy’s EBIT included net unrealized gains of $15 million pre-tax ($10 million after tax) due to changes in the fair value of proprietary natural gas storage inventory and natural gas forward purchase and sale contracts.

• Third quarter 2007, Net Income included $15 million of favourable income tax reassessments and associated interest income relating to prior years.

SECOND QUARTER REPORT 2009

Notes to Consolidated Financial Statements

(Unaudited)

1. Significant Accounting Policies

The consolidated financial statements of TransCanada Corporation (TransCanada or the Company) have been prepared in accordance with Canadian generally accepted accounting principles (GAAP). The accounting policies applied are consistent with those outlined in TransCanada's annual audited Consolidated Financial Statements for the year ended December 31, 2008, except as described in Note 2. These Consolidated Financial Statements reflect all normal recurring adjustments that are, in the opinion of management, necessary to present fairly the financial position and results of operations for the respective periods. These Consolidated Financial Statements do not include all disclosures required in the annual financial statements and should be read in conjunction with the 2008 audited Consolidated Financial Statements included in TransCanada’s 2008 Annual Report. Unless otherwise indicated, “TransCanada“ or “the Company“ includes TransCanada Corporation and its subsidiaries. Amounts are stated in Canadian dollars unless otherwise indicated. Certain comparative figures have been reclassified to conform with the current year’s presentation.

In Pipelines, which consists primarily of the Company's investments in regulated pipelines and regulated natural gas storage facilities, annual revenues and net income fluctuate over the long term based on regulators' decisions and negotiated settlements with shippers. Generally, quarter-over-quarter revenues and net income during any particular fiscal year remain relatively stable with fluctuations resulting from adjustments being recorded due to regulatory decisions and negotiated settlements with shippers, seasonal fluctuations in short-term throughput volumes on U.S. pipelines, acquisitions and divestitures, and developments outside of the normal course of operations.

In Energy, which consists primarily of the Company’s investments in electrical power generation plants and non-regulated natural gas storage facilities, quarter-over-quarter revenues and net income are affected by seasonal weather conditions, customer demand, market prices, planned and unplanned plant outages, acquisitions and divestitures, certain fair value adjustments and developments outside of the normal course of operations.

In preparing these financial statements, TransCanada is required to make estimates and assumptions that affect both the amount and timing of recording assets, liabilities, revenues and expenses as the determination of these items may be dependent on future events. The Company uses the most current information available and exercises careful judgement in making these estimates and assumptions. In the opinion of management, these consolidated financial statements have been properly prepared within reasonable limits of materiality and within the framework of the Company’s significant accounting policies.

2. Changes in Accounting Policies

The Company’s accounting policies have not changed materially from those described in TransCanada’s 2008 Annual Report except as follows:

2009 Accounting Changes

Rate-Regulated Operations

Effective January 1, 2009, the temporary exemption was withdrawn from the Canadian Institute of Chartered Accountants (CICA) Handbook Section 1100 “Generally Accepted Accounting Principles”, which permitted the recognition and measurement of assets and liabilities arising from rate regulation. In addition, Section 3465 “Income Taxes” was amended to require the recognition of future income tax assets and liabilities for rate-regulated entities. The Company chose to adopt accounting policies consistent with the U.S. Financial Accounting Standards Board’s Financial Accounting Standard (FAS) 71 “Accounting for the Effects of Certain Types of Regulation”. As a result, TransCanada retained its current method of accounting for its rate-regulated operations, except that TransCanada is required to recognize future income tax assets and liabilities, instead of using the taxes payable method, and records an offsetting adjustment to regulatory assets and liabilities. As a result of adopting this accounting change, additional future income tax liabilities and a regulatory asset in the amount of $1.4 billion were recorded January 1, 2009 in each of Future Income Taxes and Other Assets, respectively.

Adjustments to the 2009 financial statements have been made in accordance with the transitional provisions for Section 3465, which required a cumulative adjustment in the current period to future income taxes and a regulatory asset. Restatement of prior periods’ financial statements was not permitted under Section 3465.

TRANSCANADA [40

SECOND QUARTER REPORT 2009

Intangible Assets

Effective January 1, 2009, the Company adopted CICA Handbook Section 3064 “Goodwill and Intangible Assets“, which replaced Section 3062 “Goodwill and Other Intangible Assets”. Section 3064 gives guidance on the recognition of intangible assets as well as the recognition and measurement of internally developed intangible assets. In addition, Section 3450 “Research and Development Costs” was withdrawn from the Handbook. Adopting this accounting change did not have a material effect on the Company’s financial statements.

Credit Risk and the Fair Value of Financial Assets and Financial Liabilities

Effective January 1, 2009, the Company adopted the accounting provisions of Emerging Issues Committee (EIC) Abstract EIC 173, “Credit Risk and the Fair Value of Financial Assets and Financial Liabilities”. Under EIC 173 an entity’s own credit risk and the credit risk of its counterparties is taken into account in determining the fair value of financial assets and financial liabilities, including derivative instruments. Adopting this accounting change did not have a material effect on the Company’s financial statements.

Future Accounting Changes

International Financial Reporting Standards

The CICA’s Accounting Standards Board announced that Canadian publicly accountable enterprises are required to adopt International Financial Reporting Standards (IFRS), as issued by the International Accounting Standards Board (IASB), effective January 1, 2011. The Company will prepare its financial statements under IFRS commencing January 1, 2011.

Under existing Canadian GAAP, TransCanada follows specific accounting policies unique to a rate-regulated business. TransCanada is actively monitoring developments regarding potential future guidance on the applicability of certain aspects of rate-regulated accounting under IFRS. Developments in this area could have a significant effect on the scope of the Company's IFRS project and on TransCanada’s financial results under IFRS. On July 23, 2009, the IASB issued an exposure draft “Rate-regulated Activities” and the Company is assessing the impact of this exposure draft on TransCanada.

At the current stage of its IFRS project, TransCanada cannot reasonably determine the full impact that adopting IFRS would have on its financial position and future results.

TRANSCANADA [41

SECOND QUARTER REPORT 2009

Financial Instruments Disclosure

The CICA implemented revisions to Handbook Section 3862 “Financial Instruments – Disclosures” for fiscal years ending after September 30, 2009. These revisions are intended to align the disclosure requirements for financial instruments to the maximum extent possible with the disclosure required under IFRS. These revisions require additional disclosure based on a three level hierarchy that reflects the significance of inputs used in measuring fair value. Fair values of assets and liabilities included in Level 1 are determined by reference to quoted prices in active markets for identical assets and liabilities. Fair values of assets and liabilities included in Level 2 include valuations using inputs other than quoted prices for which all significant outputs are observable, either directly or indirectly. Fair values of assets and liabilities included in Level 3 valuations are based on inputs that are unobservable and significant to the overall fair value measurement. These changes will be applied by TransCanada effective December 31, 2009.

3.   Segmented Information

Effective January 1, 2009, TransCanada revised its presentation of certain income and expense items in the Consolidated Statement of Income to better reflect the operating and financing structure of the Company. To conform with the new presentation, certain of the income and expense amounts pertaining to operations that were previously classified on the Consolidated Income Statement as Other Expenses/(Income) are now included in Operating and Other Expenses/(Income). Depreciation expense has been redefined as Depreciation and Amortization expense and includes amortization of $15 million and $29 million in the three and six month periods ended June 30, 2009, respectively (2008 - $15 million and $29 million, respectively), for power purchase arrangements, which were previously included in Commodity Purchases Resold. Support services costs previously allocated to Pipelines and Energy of $31 million and $62 million in the three and six month periods ended June 30, 2009 (2008 - $25 million and $51 million, respectively), are now included in Corporate. In addition, amounts related to interest expense and financial charges of joint ventures, interest income and other, income taxes and non-controlling interests are no longer reported on a segmented basis. Segmented information has been retroactively reclassified to reflect all changes. These changes had no impact on Consolidated Net Income.

SECOND QUARTER REPORT 2009

4. Long-Term Debt

On April 23, 2009, TCPL filed a $2.0 billion Canadian Medium-Term Notes shelf prospectus to replace a March 2007 $1.5 billion Canadian Medium-Term Notes shelf prospectus, which expired in April 2009. No amounts have been issued under this shelf prospectus.

In February 2009, TCPL issued Medium-Term Notes of $300 million and $400 million maturing in February 2014 and February 2039, respectively, and bearing interest at 5.05 per cent and 8.05 per cent, respectively. These notes were issued under the $1.5 billion debt shelf prospectus filed in March 2007.

In January 2009, TCPL issued Senior Unsecured Notes of US$750 million and US$1.25 billion maturing in January 2019 and January 2039, respectively, and bearing interest at 7.125 per cent and 7.625 per cent, respectively. These notes were issued under a US$3.0 billion debt shelf prospectus filed in January 2009, which now has capacity of US$1.0 billion remaining.

In the three and six months ended June 30, 2009, the Company capitalized interest related to capital projects of $63 million and $117 million, respectively (2008 - - $32 million and $59 million).

5. Share Capital

On June 24, 2009, TransCanada completed a public offering of 50.8 million common shares. On June 30, 2009, an additional 7.6 million common shares were issued upon exercise of an underwriters’ over-allotment option. Proceeds from the common share offering and the over-allotment option totalled $1.8 billion.

In the three and six months ended June 30, 2009, TransCanada issued 1.4 million and 3.5 million common shares, respectively, under its Dividend Reinvestment and Share Purchase Plan (DRP), in lieu of making cash dividend payments totalling $42 million and $109 million. In the three and six months ended June 30, 2008, TransCanada issued 1.7 million and 3.1 million common shares, respectively, under its DRP, in lieu of making cash dividend payments totalling $58 million and $112 million. The dividends under the DRP were paid with common shares issued from treasury.

6. Financial Instruments and Risk Management

TransCanada continues to manage and monitor its exposure to market, counterparty credit and liquidity risk.

Counterparty Credit and Liquidity Risk

TransCanada’s maximum counterparty credit exposure with respect to financial instruments at the balance sheet date, without taking into account security held, consisted primarily of the carrying amount, which approximates fair value, of non-derivative financial assets, such as accounts receivable, as well as the fair value of derivative assets. Letters of credit and cash are the primary types of security provided to support these amounts. The Company does not have significant concentrations of counterparty credit risk with any individual counterparties and the majority of counterparty credit exposure is with counterparties who are investment grade. At June 30, 2009, there were no significant amounts past due or impaired.

As the uncertainty in the global financial markets persists, TransCanada continues to closely monitor and reassess the creditworthiness of its counterparties. This has resulted in TransCanada reducing or mitigating its exposure to certain counterparties where it is deemed warranted and permitted under contractual terms. As part of its ongoing operations, TransCanada must balance its market and counterparty credit risks when making business decisions.

TRANSCANADA [44

SECOND QUARTER REPORT 2009

The Company continues to manage its liquidity risk by ensuring sufficient cash and credit facilities are available to meet its operating and capital expenditure obligations when due, under both normal and stressed economic conditions.

VaR Analysis

TransCanada uses a Value-at-Risk (VaR) methodology to estimate the potential impact from its exposure to market risk on its open liquid positions. VaR represents the potential change in pre-tax earnings over a given holding period. It is calculated assuming a 95 per cent confidence level that the daily change resulting from normal market fluctuations in its open positions will not exceed the reported VaR. TransCanada’s consolidated VaR was $14 million at June 30, 2009 (December 31, 2008 – $23 million). The decrease from December 31, 2008 was primarily due to decreased prices and lower open positions in the U.S. Power portfolio.

Natural Gas Inventory

At June 30, 2009, the fair value of proprietary natural gas inventory held in storage as measured using a weighted average of forward prices for the following four months less selling costs was $44 million (December 31, 2008 - $76 million). Prior to second quarter 2009, inventory was measured using the one-month forward price. The impact of this change was insignificant.

The change in fair value of proprietary natural gas inventory in the three and six months ended June 30, 2009 resulted in pre-tax net unrealized losses of $6 million and $29 million, respectively, which were recorded as a decrease to Revenues and Inventories (gains of $42 million and $102 million for the three and six months ended June 30, 2008). The net change in fair value of natural gas forward purchase and sales contracts in the three and six months ended June 30, 2009 resulted in a pre-tax net unrealized loss of $1 million and a pre-tax net unrealized gain of $9 million (losses of $30 million and $107 million for the three and six months ended June 30, 2008), respectively, which were included in Revenues.

Net Investment in Self-Sustaining Foreign Operations

The Company hedges its net investment in self-sustaining foreign operations with U.S. dollar-denominated debt, cross-currency swaps and foreign exchange forward contracts and options. At June 30, 2009, the Company had designated as a net investment hedge U.S. dollar-denominated debt with a carrying value of $8.8 billion (US$7.6 billion) and a fair value of $9.2 billion (US$7.9 billion). At June 30, 2009, Deferred Amounts included $124 million for the fair value of derivatives used to hedge the Company’s net U.S. dollar investment in foreign operations.

(4) Realized and unrealized gains and losses on power, natural gas and oil products derivative financial instruments held for trading are included in Revenues. Realized and unrealized gains and losses on interest rate and foreign exchange derivative financial instruments held for trading are included in Interest Expense and Interest Income and Other, respectively. The effective portion of unrealized gains and losses on derivative financial instruments in hedging relationships are initially recognized in Other Comprehensive Income, and are reclassified to Revenues, Interest Expense and Interest Income and Other, as appropriate, as the original hedged item settles.

(5) All hedging relationships are designated as cash flow hedges except for interest-rate derivative financial instruments designated as fair value hedges with a fair value of $4 million and a notional amount of US$150 million. Net realized gains on fair value hedges for the three and six months ended June 30, 2009 were $1 million and $2 million, respectively, and were included in Interest Expense. In second quarter 2009, the Company did not record any amounts in Net Income related to ineffectiveness for fair value hedges.

(6) Net Income for the three and six months ended June 30, 2009 included losses of $4 million and gains of $1 million, respectively, for the changes in fair value of power and natural gas cash flow hedges that were ineffective in offsetting the change in fair value of their related underlying positions. There were no gains or losses included in Net Income for the three and six months ended June 30, 2009 for discontinued cash flow hedges. No amounts have been excluded from the assessment of hedge effectiveness.

8. Acquisition

On June 16, 2009, TransCanada announced that it will acquire ConocoPhillips’ remaining interest in Keystone for approximately US$550 million plus the assumption of approximately US$200 million of short-term indebtedness. The purchase price reflects ConocoPhillips’ capital contributions to date and includes an allowance for funds used during construction. The transaction is expected to close in third quarter 2009, subject to the receipt of certain regulatory approvals. At June 30, 2009, TransCanada’s equity ownership in the Keystone partnerships was approximately 77 per cent.

9. Commitments and Other

The Company has entered into an agreement to acquire ConocoPhillips’ remaining interest in Keystone for approximately US$550 million plus the assumption of approximately US$200 million of short-term indebtedness. The transaction is expected to close in third quarter 2009. In addition, TransCanada will also assume responsibility for ConocoPhillips’ share of the capital investment required to complete the project, which is expected to result in an incremental commitment of US$1.7 billion through the end of 2012.

Amounts received under the Bruce B floor price mechanism in any year are subject to repayment if spot prices in the remainder of that year increase above the floor price. With respect to 2009, TransCanada currently expects spot prices to be less than the floor price for the remainder of the year, therefore, no amounts recorded in revenue in the first six months of 2009 are expected to be repaid.

10. Subsequent Event

On July 1, 2009, TransCanada sold the North Baja pipeline to PipeLines LP. As part of the transaction, TransCanada agreed to amend its incentive distribution rights with PipeLines LP. TransCanada received aggregate consideration totalling approximately US$395 million from PipeLines LP, including approximately US$200 million in cash and 6,371,680 common units of PipeLines LP. PipeLines LP utilized US$170 million of its US$250 million committed and available bank facility to fund this transaction.  TransCanada’s ownership in PipeLines LP increased to 42.6 per cent as a result of this transaction.

Subsequent events have been assessed up to July 30, 2009, which is the date the financial statements were issued.

TRANSCANADA CORPORATION

RECONCILIATION TO UNITED STATES GAAP

June 30, 2009

TRANSCANADA CORPORATION

RECONCILIATION TO UNITED STATES GAAP

The unaudited consolidated financial statements of TransCanada Corporation (TransCanada or the Company) for the six months ended June 30, 2009 have been prepared in accordance with Canadian generally accepted accounting principles (GAAP), which in some respects, differ from United States (U.S.) GAAP.

The effects of significant differences between Canadian and U.S. GAAP on the Company’s consolidated financial statements for the three and six month periods ended June 30, 2009 are described below and should be read in conjunction with TransCanada’s 2008 audited consolidated financial statements and U.S. GAAP reconciliation for the year ended December 31, 2008 and unaudited consolidated financial statements for the three and six month periods ended June 30, 2009 prepared in accordance with Canadian GAAP.

(1) As required by Statement of Financial Accounting Standard (SFAS) 160 “Noncontrolling Interests in Consolidated Financial Statements – an amendment of ARB No.51”, the Company has reclassified its non-controlling interests on the income statement and balance sheet. On the balance sheet, non-controlling interests are now presented in the equity section. On the income statement, consolidated net income includes both the Company’s and the non-controlling interests’ share of net income. In addition, consolidated net income attributable to the Company and the non-controlling interests are separately disclosed. This reclassification has been applied retrospectively as required.

(2) In accordance with Canadian GAAP, natural gas inventory held in storage is recorded at its fair value. Under U.S. GAAP, inventory is recorded at lower of cost or market.

(3) In accordance with Canadian GAAP, the Company recorded current income tax benefits resulting from substantively enacted Canadian federal income tax legislation. Under U.S. GAAP, the legislation must be fully enacted for income tax adjustments to be recorded.

(4) Represents the amortization of net loss and prior service cost amounts recorded in accumulated other comprehensive income under SFAS No.158 “Employers’ Accounting for Defined Benefit Pension and Other Postretirement Plans” for the Company’s defined benefit pension and other postretirement plans.

(5) Under Canadian GAAP, pre-development costs incurred during the commissioning phase of a new project are deferred until commercial production levels are achieved. After such time, those costs are amortized over the estimated life of the project. Under U.S. GAAP, such costs are expensed as incurred. Certain development costs incurred by Bruce Power L.P., an equity investment, were expensed under U.S. GAAP.

(6) Under Canadian GAAP, the Company accounts for certain investments using the proportionate consolidation basis whereby the Company’s proportionate share of the assets, liabilities, revenues, expenses and cash flows are included in the Company’s financial statements.  U.S. GAAP does not allow the use of proportionate consolidation and requires that such investments be recorded on an equity accounting basis.  Information on the balances that have been proportionately consolidated is located in Note 8 to the Company’s audited consolidated annual financial statements for the year ended December 31, 2008.  As a consequence of using equity accounting for U.S. GAAP, the Company is required to reflect an additional liability of $179 million at June 30, 2009 (December 31, 2008 - $51 million) for the estimated fair value of certain guarantees related to debt and other performance commitments of the joint venture operations that were not required to be recorded when the underlying liability was reflected on the balance sheet under the proportionate consolidation method of accounting.

(7) Under U.S. GAAP SFAS 71 “Accounting for the Effects of Certain Types of Regulation”, the Company is required to record a deferred income tax liability for its cost-of-service regulated businesses and a corresponding regulatory asset.  Effective January 1, 2009, the Company chose to adopt accounting policies consistent with SFAS 71 for its Canadian GAAP financial statements.  Therefore, this U.S. GAAP difference has been eliminated subsequent to December 31, 2008.

(8) In accordance with U.S. GAAP, debt issue costs are recorded as a deferred asset rather than being included in long-term debt as required by Canadian GAAP.

(9) At June 30, 2009, Accumulated Other Comprehensive Income in accordance with U.S. GAAP is $195 million higher than under Canadian GAAP.  The difference relates to the accounting treatment for defined benefit pension and other postretirement plans.

Fair Value Measurements

The Company adopted the provisions of SFAS No. 157 “Fair Value Measurements” for its financial assets and liabilities measured at fair value on a recurring basis effective January 1, 2008.  Effective January 1, 2009, the Company adopted the provisions of SFAS No. 157 for all non-financial assets and liabilities that are measured at fair value on a non-recurring basis. These non-financial items include assets and liabilities such as non-financial assets and liabilities assumed in a business combination, reporting units measured at fair value in a goodwill impairment test and asset retirement obligations initially measured at fair value.

SFAS No. 157 defines fair value, establishes a framework for measuring fair value and expands disclosures about fair value measurements. Under SFAS No. 157, fair value is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., the ‘exit price’) in an orderly transaction between market participants at the measurement date. 

The Company’s financial assets and liabilities that are recorded at fair value on a recurring basis have been categorized into one of three categories based upon a fair value hierarchy in accordance with SFAS No. 157.  Fair values of assets and liabilities included in Level I are determined by reference to quoted prices in active markets for identical assets and liabilities.  Assets and liabilities in Level II include valuations using inputs other than quoted prices for which all significant outputs are observable, either directly or indirectly.   Level III valuations are based on inputs that are unobservable and significant to the overall fair value measurement. Long-dated commodity transactions in certain markets and the fair value of guarantees are included in this category. There is no current period disclosure required under SFAS No. 157 for items measured at fair value on a non-recurring basis. 

Assets and liabilities measured at fair value on a recurring basis as of June 30, 2009, including both current and non-current portions, are categorized in accordance with SFAS No. 157 as follows:

(unaudited) (millions of dollars)	Quoted prices in active markets (Level I)		Significant other observable inputs (Level II)		Significant unobservable inputs  (Level III)		Total
Derivative Financial Instruments:
Assets	95		540		-		635
Liabilities	(155	)	(689	)	(22	)	(866	)
Non-Derivative Financial Instruments Available for Sale:
Assets	23		-		-		23
Guarantees:
Liabilities	-		-		(190	)	(190	)
Total	(37	)	(149	)	(212	)	(398	)

Long-term debt fair value disclosures are based on quoted market prices for same or similar debt instruments, or, when not available, by discounting future payments of interest and principal at estimated interest rates.  These fair value disclosures fall under Level II in the SFAS No. 157 hierarchy.

Page 4

The following table presents the net change in assets and liabilities measured at fair value on a recurring basis and included in the Level III fair value category:

(unaudited)	3 Months Ended June 30				6 Months Ended June 30

(1) The fair value of derivative assets and liabilities are presented on a net basis.

(2) The fair value of guarantees is recognized in long-term investments and deferred amounts.  No amounts were recognized in earnings for the periods presented.  The fair value was previously included in the Level II fair value category.

Disclosures about Hedging Instruments and Hedging Activities

The Company adopted the provisions of SFAS No. 161 “Disclosures about Derivative Instruments and Hedging Activities” effective January 1, 2009.  The statement is intended to enhance the current disclosure requirements to provide more information about how derivatives and hedging activities affect an entity’s financial position, financial performance and cash flows.  Many of these disclosures are provided in the Company’s consolidated financial statements prepared under Canadian GAAP.  Additional information required by SFAS No. 161 is provided below.

Derivative contracts entered into to manage market risk often contain financial assurances provisions that allow parties to the contracts to manage credit risk.  These provisions may require collateral to be provided if a credit-risk-related contingent event occurs, such as a downgrade in the Company’s credit rating to non-investment grade.  Based on contracts in place and market prices at June 30, 2009, the aggregate fair value of all derivative instruments with credit-risk-related contingent features that are in a net liability position is $148 million for which the Company has provided collateral of $12 million in the normal course of business.  If the credit-risk-related contingent features in these agreements were triggered on June 30, 2009, the Company may be required to provide additional collateral of $136 million to its counterparties.  The Company has sufficient liquidity in the form of cash and undrawn committed revolving bank lines to meet these contingent obligations should they arise.

Income Taxes

At June 30, 2009, the total unrecognized tax benefit is approximately $72 million (December 31, 2008 - $80 million).  TransCanada’s continuing practice is to recognize interest and penalties related to income tax uncertainties in income tax expense.  Included in net tax expense for the six month period ended June 30, 2009 is $3 million of interest income and nil for penalties (June 30, 2008 - $6 million for interest expense and nil for penalties). At June 30, 2009, the Company had $22 million accrued for interest and nil accrued for penalties (December 31, 2008 - $24 million accrued for interest and nil accrued for penalties).

TransCanada expects the enactment of certain Canadian Federal tax legislation in the next twelve months.  This legislation will result in a favourable income tax adjustment of approximately $13 million.  Otherwise, subject to the results of audit examinations by taxing authorities and other legislative amendments, TransCanada does not anticipate further adjustments to the unrecognized tax benefits during the next twelve months that would have a material impact on its financial statements.

Changes in Accounting Policies

2009 Accounting Changes

In December 2007, Financial Accounting Standards Board (FASB) issued SFAS No. 160 and SFAS No. 141(R) “Business Combinations” both of which are effective for annual and interim periods beginning after December 15, 2008. SFAS No. 160 requires that third party ownership interests in subsidiaries be presented separately in the equity section of the balance sheet.  Consolidated net income will include both the shareholders’ and the non-controlling interests’ share of net income. SFAS No. 141(R) requires that most identifiable assets, liabilities (including obligations for contingent consideration), non-controlling interests and goodwill be recorded at “full fair value”.  Also, for step acquisitions, the acquirer will be required to re-measure its non-controlling equity investment in the acquiree at fair value as of the date control is obtained and recognize any gain or loss in income.  The Company adopted these standards on January 1, 2009 resulting in a reclassification of non-controlling interests on the income statement and balance sheet.

In April 2009, FASB issued Staff Position No. 141(R)-1 “Accounting for Assets Acquired and Liabilities Assumed in a Business Combination That Arise from Contingencies” which amends and clarifies SFAS No. 141(R).  Any asset or liability assumed in a business combination that arises from a contingency will be recognized at the fair value at the acquisition date if that fair value can be determined.  If the acquisition-date fair value cannot be determined, then the asset or liability will only be recognized if it is probable that the asset existed or the liability had been incurred at the acquisition date and the amount can be reasonable estimated.  This Staff Position is effective for acquisitions after December 15, 2008.  The Company will apply this standard as appropriate on future business combinations.

In April 2009, FASB issued Staff Position No. 107-1 and APB 28-1 “Interim Disclosures about Fair Value of Financial Instruments” which amends SFAS No. 107 “Disclosures about Fair Value of Financial Instruments” to require fair value disclosure for interim reporting periods in addition to annual financial statements.  This Staff Position will be effective for interim reporting periods after June 15, 2009.  The Company adopted these standards for its second-quarter 2009 report by expanding its financial instrument disclosure.

In April 2009, FASB issued Staff Position No. 115-2 and SFAS No. 124-2 “Recognition and Presentation of Other-Than-Temporary Impairments” which amends the guidance related to other-than-temporary impairments specifically for debt securities.  Other-than-temporary impairments must be recognized if the entity has the intention of selling the debt security or if it is more likely than not that the entity will be required to sell the debt security before its anticipated recovery.  This Staff Position will be effective for interim reporting periods after June 15, 2009.  The Company adopted these standards for its second-quarter 2009 report without a material impact to its financial statements.

In May 2009, FASB issued SFAS No. 165 “Subsequent Events” which establishes general standards of accounting for and disclosure of events that occur after the balance sheet date but before financial statements are issued or available to be issued.  The accounting and disclosure requirements under this standard have been incorporated in the Company’s Canadian GAAP financial statements, therefore, there was no impact on the Company’s U.S. GAAP financial statements.

Future Accounting Changes

In December 2008, FASB issued Staff Position No. 132(R)-1 “Employers’ Disclosures about Postretirement Benefit Plan Assets”, which requires more detailed disclosures regarding the employers’ plan assets, concentrations of risk within plan assets and valuation techniques used to measure the fair value of plan assets. This Staff Position will be effective for fiscal years ending after December 15, 2009. The Company will adopt these standards for its 2009 year-end reporting by expanding its postretirement benefit plan disclosures.

TransCanada Reports Second Quarter Net Income of $314 Million or $0.50 Per Share

Funds Generated from Operations of $692 million

CALGARY, Alberta – July 30, 2009 – TransCanada Corporation (TSX, NYSE: TRP) (TransCanada or the Company) today announced net income for second quarter 2009 of $314 million or $0.50 per share. TransCanada’s Board of Directors also declared a quarterly dividend of $0.38 per common share.

“Our solid second quarter performance in the face of historically low power prices in Alberta and Ontario demonstrates the inherent strength of our business model and the quality of our existing assets,” said Hal Kvisle, TransCanada’s president and chief executive officer. “Looking forward, our strong internally generated cash flow and prudent decisions to maintain TransCanada’s financial strength means we are well positioned to fund our large capital program. While the carrying costs and dilution associated with recent financings will continue to have an impact on our financial results through the remainder of 2009, we expect significant growth in earnings and cash flow over the next four years as $21 billion of secured, low-risk projects are placed into service.”

Second Quarter 2009 Highlights

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

§   Net income of $314 million or $0.50 per share

§   Comparable earnings of $319 million or $0.51 per share

§   Comparable earnings before interest, taxes, depreciation and amortization (EBITDA) of $1.0 billion

§   Funds generated from operations of $692 million

§   Dividend of $0.38 per common share declared by the Board of Directors

§   Continued to advance TransCanada’s $21 billion capital program

§   Announced that TransCanada will become the sole owner of the US$12 billion Keystone Oil Pipeline System

§   Issued approximately $1.8 billion of common shares to help fund the Company’s capital program

TransCanada reported net income for second quarter 2009 of $314 million ($0.50 per share) compared to $324 million ($0.58 per share) for second quarter 2008.

Comparable earnings were $319 million in second quarter 2009 compared to $316 million for the same period in 2008. The increase in comparable earnings was primarily due to higher earnings from Bruce Power, Eastern Power, Natural Gas Storage, and U.S. Pipelines, partially offset by a decrease in Western Power and higher financing costs. Comparable earnings per share of $0.51 in second quarter 2009 decreased from $0.57 per share for the same period in 2008 due to an increase in the average number of shares outstanding following the Company’s common share issuances in the second and fourth quarters of 2008 and the second quarter of 2009. Comparable earnings in second quarter 2009  and 2008 excluded $5 million of after tax unrealized losses, and $8 million of after tax unrealized gains, respectively, resulting from changes in the fair value of proprietary natural gas inventory and natural gas forward purchase and sale contracts.

Comparable EBITDA in second quarter 2009 of $1,017 million increased $69 million compared to $948 million in second quarter 2008.

Funds generated from operations in second quarter 2009 were $692 million compared to $676 million in second quarter 2008.

Notable recent developments in Pipelines, Energy and Corporate include:

Pipelines:

§   TransCanada reached an agreement to acquire ConocoPhillips’ remaining interest in the Keystone Oil Pipeline System (Keystone) for approximately US$550 million plus the assumption of approximately US$200 million of short-term indebtedness. The transaction is expected to close in third quarter 2009, subject to the receipt of certain regulatory approvals.

TransCanada will assume responsibility for ConocoPhillips’ share of the capital investment required to complete the project resulting in an incremental commitment of approximately US$1.7 billion through the end of 2012.

When completed, the US$12 billion pipeline will be one of the largest oil delivery systems in North America with the capacity to deliver 1.1 million barrels per day (bbl/d) from Western Canada to the largest refining markets in the United States. To date, Keystone has secured long-term commitments for 910,000 bbl/d for an average term of approximately 18 years which represents 83 per cent of the commercial design of the system. At July 30, 2009, the first phase was approximately 80 per cent complete.

Keystone is expected to begin to generate EBITDA in first quarter 2010, when commercial operations to Wood River and Patoka, Illinois commence, and increase through 2011 and 2012 as subsequent phases of Keystone are placed in service. Based on current long-term commitments of 910,000 bbl/d, Keystone is expected to generate EBITDA of approximately US$1.2 billion in 2013, its first full year of commercial operation serving both the U.S. Midwest and Gulf Coast markets. If volumes increase to 1.1 million bbl/d, Keystone would generate approximately US$1.5 billion of annual EBITDA. 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 entered into a contract to build, own and operate the US$320 million Guadalajara Pipeline in Mexico, supported by a 25-year contract for its entire capacity with Comisión Federal de Electricidad, Mexico’s state-owned electric company. The proposed pipeline will extend 310 kilometres (kms) (193 miles) from an LNG terminal under construction near Manzanillo, Mexico, to Guadalajara, and is expected to be capable of transporting 500 million cubic feet per day of natural gas.  The Company expects to complete most of the construction in 2010 with a targeted in-service date of March 2011.

§   TransCanada sold the North Baja Pipeline (North Baja), to TC PipeLines, LP (PipeLines LP) on July 1, 2009. As part of the transaction, TransCanada agreed to amend its incentive distribution rights with PipeLines LP.  TransCanada received aggregate consideration totalling approximately US$395 million from PipeLines LP, including approximately US$200 million in cash and 6,371,680 common units of PipeLines LP.  TransCanada’s ownership in PipeLines LP increased to 42.6 per cent as a result of this transaction.  TransCanada will continue to operate the North Baja Pipeline.

§   TransCanada submitted an application in April 2009 to the National Energy Board (NEB) for approval to construct and operate the Groundbirch Pipeline, which comprises a 77 km (48 mile) natural gas pipeline and related facilities.  The Groundbirch Pipeline is an extension of the Alberta System which is expected to connect natural gas supply primarily from the Montney shale gas region in northeast B.C. to existing infrastructure in northwest Alberta. In June 2009, the NEB announced that it will hold a public hearing process on the application.  Subject to regulatory approvals, construction of the Groundbirch Pipeline is expected to commence in July 2010 with final completion anticipated in November 2010.

§   TransCanada filed a project description in May 2009 with the NEB to construct the Horn River natural gas pipeline.  The Horn River Pipeline is a proposed extension of the Alberta System to service the Horn River shale gas region in northeast B.C. Horn River producers have recently notified TransCanada that they are extending their construction schedule for upstream production facilities which will enhance their ability to manage project costs, therefore, TransCanada will delay the in-service date of the Horn River Pipeline from 2011 to 2012.

§   TransCanada and ExxonMobil Corporation reached an agreement to work together to progress TransCanada’s Alaska Pipeline Project. With a forecasted capital cost of US$26 billion (2007 estimate in 2007 dollars), the project would provide a variety of benefits to Alaska and Canada, as well as the rest of the United States including substantial revenues, jobs, business opportunities and new, long-term stable supplies of natural gas.

The Alaska Pipeline Project continues to move forward with project development, including engineering, environmental reviews, Alaska Native and Canadian Aboriginal engagement, and commercial work to conclude an initial binding open season by July 2010.  Subject to the completion of a successful open season, construction of the approximately 2,700 km (1,700 mile), 4.5 billion cubic feet per day pipeline is expected to begin in 2016, once environmental and regulatory approvals are received, and begin transporting natural gas in 2018.

Energy:

§   On July 6, 2009, Bruce Power and the Ontario Power Authority (OPA) amended certain terms and conditions included in the Bruce Power Refurbishment Implementation Agreement. The amendments are consistent with the original intent of the contract, which was signed in 2005, and recognize the significant changes in Ontario’s electricity market. The changes are outlined in more detail in the recent developments section of TransCanada’s Second Quarter 2009 Management’s Discussion and Analysis.

§   TransCanada continues to advance construction on the Kibby Wind Power (Kibby) project including the installation of 22 turbines which are expected to be completed this summer.  Kibby is expected to have the capacity to produce 132 megawatts (MW) of power when complete, with commissioning of the first phase of the project to begin in late 2009.

§   Construction of the 683 MW Halton Hills generating station also continued and it is anticipated to be in service in the third quarter of 2010.

§   TransCanada expects to begin construction of the US$500 million Coolidge Generating Station in August 2009. The 575 MW power facility is expected to be online by the end of second quarter 2011. The simple-cycle, natural gas-fired peaking facility, with the capacity to power 575,000 homes, will provide a quick response to peak power demand. The facility will also provide reserve capacity and the ability to generate power quickly to support power reliability in the region. 

§   The Government of Québec approved the construction of the 212 MW Gros-Morne and 58 MW Montagne-Sèche wind farms on June 10, 2009.  Representing an investment of approximately $340 million, both wind farms are expected to be operational by 2012. These are the fourth and fifth Québec-based wind farms under development by Cartier Wind, which is 62 per cent owned by TransCanada.

 Corporate:

§   The Company and its subsidiaries held cash and cash equivalents of $3.5 billion at June 30, 2009.

§   On June 24, 2009, TransCanada completed a public offering of 50.8 million common shares. On June 30, 2009, an additional 7.6 million common shares were issued upon exercise of the underwriters’ over-allotment option. Proceeds from the common share offering and over-allotment option totalled $1.8 billion and will be used by TransCanada to partially fund capital projects of the Company, including the acquisition of the remaining interest in Keystone, for general corporate purposes and to repay short-term indebtedness.

§   With this recent common share offering, TransCanada is well positioned to fund its existing capital program through its growing internally-generated cash flow, its dividend reinvestment plan and the issuance of long-term debt, supplemented by further subordinated capital, as required, in the form of preferred shares or other hybrid securities. As demonstrated by the recent sale of North Baja, TransCanada will also continue to examine opportunities for portfolio management, including an ongoing role for PipeLines LP, in the financing of TransCanada’s capital program.

Forward-looking statements in this document are intended to provide TransCanada securityholders and potential investors with information regarding TransCanada and its subsidiaries, including management’s assessment of TransCanada’s and its subsidiaries’ future financial and operations plans and outlook.  Forward-looking statements in this document may include, among others, statements regarding the anticipated business prospects and financial performance of TransCanada and its subsidiaries, expectations or projections about the future, and strategies and goals for growth and expansion.All forward-looking statements reflect TransCanada’s beliefs and assumptions based on information available at the time the statements were made. Actual results or events may differ from those predicted in these forward-looking statements. Factors that could cause actual results or events to differ materially from current expectations include, among others, the ability of TransCanada to successfully implement its strategic initiatives and whether such strategic initiatives will yield the expected benefits, the operating performance of TransCanada’s pipeline and energy assets, the availability and price of energy commodities, capacity payments, regulatory processes and decisions, changes in environmental and other laws and regulations, competitive factors in the pipeline and energy sectors, construction and completion of capital projects, labour, equipment and material costs, access to capital markets, interest and currency exchange rates, technological developments and the current economic conditions in North America. By its nature, forward-looking information is subject to various risks and uncertainties, which could cause TransCanada's actual results and experience to differ materially from the anticipated results or expectations expressed. Additional information on these and other factors is available in the reports filed by TransCanada with Canadian securities regulators and with the U.S. Securities and Exchange Commission (SEC). Readers are cautioned to not place undue reliance on this forward-looking information, which is given as of the date it is expressed in this news release or otherwise, and to not use future-oriented information or financial outlooks for anything other than their intended purpose.

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.

Management uses the measures of comparable earnings, EBITDA and EBIT to better evaluate trends in the Company’s underlying operations. Comparable earnings, comparable EBITDA and comparable EBIT comprise net income, 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 MD&A presents a reconciliation of comparable earnings, comparable EBITDA, comparable EBIT and EBIT to Net Income. Comparable earnings per share is calculated by dividing comparable earnings by the weighted average number of shares outstanding for the period.

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.

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 "Liquidity and Capital Resources" section of this MD&A.
