TransAlta Corporation (TransAlta or the Company) (TSX: TA; NYSE: TAC) today reported second quarter 2017 comparable EBITDA⁽¹⁾ of $268 million, funds from operations (FFO)⁽¹⁾ of $187 million, and free cash flow (FCF)⁽¹⁾ of $30 million. Comparable EBITDA and FFO for the second quarter are the highest second quarter results in over five years, and increased by $20 million and $12 million, respectively, over the same period last year.

The second quarter results reflect strong performance across our portfolio. US Coal benefited from favourable mark-to-market impacts on financial contracts, higher contracted revenue, and lower costs for purchased power; Wind and Solar profited from stronger wind resources in eastern Canada and lower operating expenses; Hydro benefitted from higher water resources; and the gross margin from Energy Marketing returned to historic levels.  Canadian Coal, as expected, was negatively impacted by lower realized price on uncontracted volumes and higher coal costs compared to last year.

Free cash flow was down by $26 million and $15 million for the three and six months ended June 30, 2017, respectively, due to the timing of capital expenditures, higher productivity capital spending relating to our corporate transformation, and higher distributions to our partner in TransAlta Cogeneration L.P.

€œThe business operated as predicted with some upside in our renewables portfolio,- said Dawn Farrell, President and Chief Executive Officer. €œThe highlight for this reporting period is the commissioning of the South Hedland power station which will increase our dividend from TransAlta Renewables from $120 million to $150 million on an annualized basis. However, expected headwinds in the back half of the year and additional productivity capital spending have lowered our free cash flow guidance by approximately ten per cent on an annualized basis,€ commented Mrs. Farrell.

Second Quarter Highlights

• We accelerated our transition to gas and renewables generation with the announcement of our intention to retire Sundance Unit 1, mothball Sundance Unit 2, and convert Sundance Units 3 to 6 and Keephills Units 1 and 2 from coal-fired to gas-fired generation between 2021 to 2023.
• TransAlta Renewables will be investing approximately $37 million in five new towers, adding 17 MW of capacity to the existing Kent Hills wind farm. The expansion is supported by a long-term contract with New Brunswick Power Corporation, and will bring the total capacity of the Kent Hills wind farm to approximately 167 MW.  Construction of the expansion is expected to begin in the spring of 2018 and will be funded through project financing.  We expect the Kent Hills wind project to support between $240 and $275 million of project financing.
• We settled the contract indexation dispute with the Ontario Electricity Financial Corporation (OEFC). The settlement consisted of a $34 million payment to TransAlta, and relates to long-term contracts at Ottawa and Windsor, which form part of TransAlta Cogeneration L.P.

Important Subsequent Events

• TransAlta Renewables announced that the South Hedland power station, located in the Pilbara Region of Western Australia, had begun commercial operation. The 150 MW combined-cycle natural gas power station is expected to contribute approximately $80 million of annual EBITDA from two 25-year power purchase agreements (PPA).  As a result of the commissioning, the Class B shares in the capital of TransAlta Renewables held by TransAlta were converted into common shares, and TransAlta Renewables increased the dividend on its common shares by approximately 7%.
• Fortescue Metals Group (FMG) announced that in their view the South Hedland power station has not yet satisfied the requisite performance criteria to declare commercial operation for their 35 MW contract. In our view, all conditions to establish that commercial operations commenced have been satisfied in full under the terms of the PPA with FMG. We continue to confer on the issue with FMG.
• TransAlta cancelled the $350 million credit agreement provided to TransAlta Renewables and reduced our $1.5 billion credit facility to $1.0 billion. Concurrent with this transaction, TransAlta Renewables entered into a $500 million syndicated credit agreement, resulting in no change to liquidity for TransAlta on a consolidated basis. Both credit facilities expire in 2021.
• The Balancing Pool announced its intention to consult with customer representatives and the Minister of Energy regarding its ability to terminate certain of the power purchasing arrangements (The Alberta PPAs) that it holds and which relate to Sundance Units 1 to 6. The Balancing Pool is required to provide six months notice of any termination, and provide us with a termination payment which we estimate to be approximately $231 million.
• TransAlta appointed the Honourable Rona Ambrose to its Board of Directors. Ambrose is the former Leader of Canada’s Official Opposition in the House of Commons, and brings extensive public policy experience and demonstrated ability to bring people of divergent views together.
• We received notice that FMG intends to repurchase the Solomon power station from TEC Pipe Pty Ltd, a wholly owned subsidiary of TransAlta, a right that FMG has under the applicable power purchase arrangement. TransAlta Renewables owns the economic interest in the Solomon facility and its gross proceeds from the repurchase are estimated to be approximately US$335 and will be utilized to repay the credit facility used to fund the development of the South Hedland power station, for other future growth opportunities, and for general corporate purposes.
• Productivity at the Highvale mine was impacted by emerging labour constraints. The temporary shortfall affects our coal-fired Sundance Units 1 to 6 and Keephills Units 1 to 3.

2017 Fiscal Outlook Update

During the first half of the year, emerging labour constraints at our Highvale mine have impacted productivity, significantly reducing our coal inventory and causing coal supply constraints for our facilities in Alberta. The shortfall affects our coal-fired Sundance generating Units 1 to 6 and Keephills Units 1 to 3. We expect additional mining costs at our Highvale mine operations for the remainder of 2017, and a shorter-term reduction in the power generation at Sundance and Keephills, in order to rebuild our coal inventory. Also, higher productivity capital and higher distributions to non-controlling interests have negatively impacted FCF.

The following table outlines TransAlta’s updated financial targets for 2017:

Measure	Revised Outlook	Previous Outlook
Comparable EBITDA	$1,025 to $1,100 million	$1,025 to $1,135 million
FFO	$765 to $820 million	$765 to $855 million
FCF	$270 to $310 million	$300 to $365 million
Dividend	$0.16 per share, 15% 17% payout of FCF	$0.16 per share, 13% 15% payout of FCF

Total Comparable EBITDA	268	248	542	527

• Canadian Coal: Comparable EBITDA for the three and six months ended June 30, 2017 decreased by $8 million and $20 million, respectively, compared to the same periods in 2016. Generation for the quarter and year-to-date was slightly higher than the comparable period in 2016, which when combined with higher payments under the Alberta PPA relating to the pass through of environmental costs, resulted in higher revenues. The three and six month periods ended June 30, 2017, also included $10 million and $20 million, respectively, in income related to accruals for the Off-Coal Agreement payment. These benefits were more than offset by lower hedged volumes and a reduction in our mark-to-market positions, attributable to long-term financial contracts, as well as higher coal costs.
• US Coal: Comparable EBITDA for the second quarter and year-to-date improved by $16 million and $30 million, respectively, compared to the corresponding periods in 2016. Favourable impacts of mark-to-market positions on certain forward financial contracts and higher revenues benefitted both the quarter and year-to-date results.  Second quarter results also benefitted from lower costs to purchase power and favourable foreign exchange rates.  Availability for the three and six months ended June 30, 2017 was down compared to 2016 due to a forced outage at Unit 1 in January.
• Canadian Gas: Comparable EBITDA for the six months ended June 30, 2017 increased by $24 million compared to 2016, primarily due to the settlement with the OEFC, partially offset by unfavourable changes in unrealized mark-to-market positions and higher labour costs.
• Australian Gas: Production for the three and six months ended June 30, 2017 increased 27 per cent and 17 per cent respectively, over the corresponding periods in 2016, due to higher customer load. The nature of our capacity payments, with a flow through of fuel costs, results in comparable EBITDA remaining stable across the periods. In July, we achieved commercial operation at our South Hedland project, which is expected to contribute approximately $80 million in EBITDA annually.
• Wind and Solar: Comparable EBITDA for the three and six months ended June 30, 2017 increased by $6 million and $13 million, respectively, compared to the same period in 2016, primarily due to increased generation at our contracted facilities in eastern Canada and lower operating expenses after renegotiating long term service agreements for service providers for some Alberta wind projects.
• Hydro: Comparable EBITDA of $28 million for the three months ended June 30, 2017 reflected an increase of $3 million, related to higher generation, compared to the same period in 2016.
• Energy Marketing: Comparable EBITDA of $12 million was $6 million higher than the same period in 2016 reflecting a return to a normalized gross margin and better performance in certain markets. On a year-to-date basis, results were lower compared to 2016 due to weak margins in the first quarter of 2017 as traders reduced their positions to manage market uncertainty.
• Corporate: Corporate overhead includes certain costs relating to our corporate transformation and reclassification of 2016 incentives between our operational and corporate segments.

Consolidated Earnings Review

Reported net loss attributable to common shareholders for the second quarter of 2017 was $18 million ($0.06 loss per share) compared to net earnings of $6 million ($0.02 earnings per share) during the same period in 2016. Year-to-date, reported net earnings were down $86 million ($0.30 loss per share). For both the quarter and year-to-date, the income related to the Off-Coal Agreement payments were offset by the Sundance Unit 1 impairment charge of $20 million recognized in the quarter and higher net earnings attributable to non-controlling interests. Additionally, the comparative net earnings for 2017 are negatively impacted by higher depreciation on Keephills 3 and Genesee 3, which were expected to run beyond 2030 and therefore have had their useful lives shortened.

Operating Review

Adjusted availability for the three and six months ended June 30, 2017 was 84.0 per cent and 86.2 per cent, respectively, compared to 86.5 per cent and 89.4 per cent for the same periods in 2016. Higher planned outages at Canadian and US Coal, and planned outages at our Sarnia cogeneration plant and Windsor plant, were the main causes of the decreases.

Production for the three and six months ended June 30, 2017 was 7,707 GWh and 16,758 GWh, respectively, compared to 7,899 GWh and 16,766 GWh for the same periods in 2016. The cessation of operations at our Mississauga cogeneration facility effective Jan. 1, 2017, and planned major maintenance at US Coal, were the main drivers of the production decrease in the second quarter of 2017. This was partially offset by higher generation at Alberta Hydro and Wind, as well as stronger customer demand in Australia.

TransAlta Corporation (TransAlta or the Company) (TSX: TA; NYSE: TAC) today reported first quarter 2017 comparable EBITDA(1) of $274 million, funds from operations (FFO)(1) of $203 million, and free cash flow (FCF)(1) of $98 million. Comparable EBITDA(1) decreased by $5 million compared to last year due to previous hedges rolling off and being replaced with lower priced hedges and as a result of higher mining costs. In addition, Energy Marketing was impacted by unusual weather in the Northeast and the Pacific Northwest and delivered below expected performance in the quarter. The recognition of the expected settlement in relation to the contract indexation dispute with the Ontario Electricity Financial Corporation (OEFC) relating to the Ottawa and Windsor generating facilities totaling $34 million, almost fully offset the shortfall in Energy Marketing and Canadian Coal. FFO and FCF for the first quarter of 2017 were up $7 million and $12 million respectively over the same period last year, due to higher realized foreign exchange gains and changes in non-cash mark-to-market value included in EBITDA.

€œFirst quarter results were comparable to 2016, we remain comfortable with our 2017 guidance for EBITDA, FFO, and FCF,- said Dawn Farrell, President and Chief Executive Officer. €œSolid free cash flow for the quarter, and the sale of Wintering Hills, contributed to our ability to decrease debt in the first quarter,€ commented Mrs. Farrell.

First Quarter Highlights

• During the quarter, total debt, net of cash, decreased by $244 million, primarily due to strong FCF, a decrease in our working capital, the sale of the Wintering Hills merchant wind facility and the impact of the weakened US dollar at quarter end.
• On March 1, 2017, we closed the previously announced sale of our 51 per cent interest in the Wintering Hills merchant wind facility for approximately $61 million. The sale provides us with near-term liquidity, increases our financial flexibility, and reduces our merchant exposure in Alberta.
• We progressed the construction of the South Hedland power project. We expect the project to be fully commissioned in mid-2017. When fully commissioned, the project is expected to generate approximately $80 million of comparable EBITDA annually.
• We progressed the expected settlement in relation to the contract indexation dispute with the OEFC. The settlement is expected to consist of a $34 million payment by the OEFC to TransAlta, of which $11 million has already been received. We have recognized the full $34 million amount in our results in the first quarter of 2017. The settlement is expected to be finalized during the second quarter.
• We announced the acceleration of our transition to gas and renewables generation with the retirement of Sundance Unit 1, the mothballing of Sundance Unit 2, and the conversion of Sundance Units 3 to 6, and Keephills Units 1 and 2 from coal-fired generation to gas-fired generation between 2021 to 2023. The retirement of Sundance Unit 1 and mothballing of Sundance Unit 2 is not expected to have a material impact on our cash flow for 2018 and 2019.

€œThe decision to convert six of our units to natural gas positions us to be a strong competitor in the Alberta power market as carbon is priced and capacity becomes more valuable,- said Mrs. Farrell. €œWe have a clear path forward that is aligned with policy, and the need to provide clean and affordable solutions for Albertans,€ added Mrs. Farrell.

Summary of Credit Agency Reviews

• Fitch Ratings reaffirmed our Unsecured Debt rating as BBB- and changed their outlook from negative to stable.
• DBRS Limited changed our Unsecured Debt rating and Medium-Term Notes rating from BBB to BBB (low), the Preferred Shares rating from Pfd-3 to Pfd-3 (low), and Issuer Rating BBB to BBB (low).
• Standard and Poor’s reaffirmed our Unsecured Debt rating and Issuer Rating from BBB- stable outlook to BBB- negative outlook.

First Quarter 2017 Review by Segment

Comparable EBITDA (in CAD$ millions)	3 Months Ended
	March 31, 2017	March 31, 2016
Canadian Coal	91	103
U.S. Coal	10	(4)
Canadian Gas	88	65
Australian Gas	31	31
Wind and Solar	68	61
Hydro	14	18
Energy Marketing	(4)	23
Corporate	(24)	(18)
Total Comparable EBITDA	274	279

• Canadian Coal: Comparable EBITDA for the three months ended March 31, 2017 decreased $12 million compared to 2016. Revenues for the quarter were positively impacted by the pass through of higher environmental compliance costs to PPA buyers. Lower hedge prices on our non-contracted generation ($7 million) and changes in our mark-to-market positions attributable to long-term financial contracts to economically hedge our future generation ($5 million) partially offset the increase in our revenues. Fuel and purchased power was impacted by lower expected production volume and a higher expected strip ratio at our mine, and higher expected environmental compliance costs in 2017. Most of the higher environmental compliance costs are offset as pass through revenue. Comparable EBITDA also includes a $10 million accrual related to Off-Coal Agreement payments included in net other operating income.
• U.S. Coal: Comparable EBITDA increased by $14 million compared to 2016. Gross margin was up $15 million as a result of higher prices on contracted sales, higher merchant sale volumes, favourable impacts of mark-to-market positions on certain forward financial contracts that do not qualify for hedge accounting, and a reduction in coal impairment charges. The weakened Canadian dollar also contributed to the higher comparable EBITDA during the first quarter of 2017.
• Canadian Gas: Comparable EBITDA for the first quarter of 2017 increased by $23 million compared to 2016, mainly due to the expected settlement of the indexation dispute for our long-term contracts at Ottawa and Windsor, partially offset by lower realized hedge gains and higher mark-to-market losses as well as lower revenues from our Windsor facility under its new contract. Mississauga, Ottawa, and Windsor generating facilities are owned through our 51 per cent interest in TA Cogeneration LP.
• Australian Gas: Comparable EBITDA for the first quarter of 2017 remained stable as our contracts are structured as capacity payments.
• Wind and Solar: Comparable EBITDA for the first quarter of 2017 increased $7 million compared to 2016, primarily due to the sale of Solar Renewable Energy Credits (SRECs) generated from our US Solar assets. In the first quarter of 2016, the SRECs that we sold had been acquired at fair value as part of the acquisition of our solar assets during the fourth quarter of 2015 and recognized as inventory in 2015. In the first quarter of 2017, sales of SRECs were internally generated with no cost in inventory. Also impacting our results this quarter were the slightly better prices in Alberta on our non-contracted generation and the indexation of our contracts in Eastern Canada.
• Hydro: Comparable EBITDA for the first quarter of 2017 decreased by $4 million compared to 2016. The first quarter of 2016 results included a prior year adjustment for metering at one of our hydro power plants.
• Energy Marketing: Comparable EBITDA decreased by $26 million compared to 2016, due to warm weather during the winter in the Northeast, significant precipitation in the Pacific Northwest, and reduced volume of trading activity in the quarter due to a reduction in the risk taken by the traders facing uncertain conditions, and a reduction in the volume of activity from our customer risk management business.
• Corporate: Corporate overhead costs of $24 million were $6 million higher in the first quarter of 2017 compared to 2016, primarily due to a reclassification of incentives for 2016 between our operational segments and corporate segment.

Consolidated Earnings Review Reported net earnings attributable to common shareholders for the quarter was nil (nil per share) compared to net earnings of $62 million ($0.22 net earnings per share) in 2016 due to higher net earnings attributable to TransAlta Renewables Inc. shareholders. Last year, net earnings in the first quarter were also positively impacted by the reduction of our reclamation obligation at our Centralia mine caused by a higher discount rate. This year, higher depreciation arose due to the shortening of useful lives of Keephills 3 and Genesee 3.

Operating Review Adjusted availability for the three months ended March 31, 2017 was 88.5 per cent compared to 92.3 per cent for the same period in 2016. Higher unplanned outages at Canadian and US Coal were the main cause of the decrease. Lower availability had a minimal impact on our results due to current low prices in Alberta and the Pacific Northwest.Production for the three months ended March 31, 2017 was 9,051 gigawatt hours (GWh), compared to 8,867 GWh for the same period in 2016, mainly due to higher production at US Coal as a result of later economic dispatching in 2017 due to higher prices, partially offset by the cessation of operations at our Mississauga cogeneration facility, effective Jan. 1, 2017, in accordance with the terms of a new contract with Ontario’s Independent Electricity System Operator (IESO). We will continue to receive monthly capacity payments from the IESO until Dec. 31, 2018.For the first quarter, sustaining capital expenditures decreased by $13 million compared to 2016, mainly due to lower planned outage expenditures. In 2016 we executed pit stops on our Sundance 1 and 2 Units as well as a large outage on Sundance Unit 4. During the first quarter of 2017, only one planned outage was performed on Sundance Unit 6.
