amortization for the three months ended March 31, 2017 increased in total by approximately $14 million and the full year 2017 depreciation

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><I>(1) During the three months ended March
31, 2017, the Corporation reversed a previous writedown of deferred income tax assets of $6 million. The deferred income tax assets
mainly relate to the tax benefits of losses associated with the Corporation&rsquo;s directly owned U.S. operations. The Corporation
had written these assets off as it was no longer considered probable that sufficient future taxable income would be available from
the Corporation&rsquo;s directly owned U.S. operations to utilize the underlying tax losses, due to reduced price growth expectations.
Recognized other comprehensive income during the period has given rise to taxable temporary differences, which forms the primary
basis for utilization of some of the tax losses and the reversal of the writedown.</I></P>

commodity risk management Level III fair value measurements are determined by the Corporation&rsquo;s risk management department.
Level III fair values are calculated within the Corporation&rsquo;s energy trading risk management system based on underlying contractual
data as well as observable and non-observable inputs. Development of non-observable inputs requires the use of judgment. To ensure
reasonability, system-generated Level III fair value measurements are reviewed and validated by the risk management and finance
departments. Review occurs formally on a quarterly basis or more frequently if daily review and monitoring procedures identify
unexpected changes to fair value or changes to key parameters.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Corporation has a long-term fixed price
power sale contract in the U.S. for delivery of power at the following capacity levels: 380 MW through Dec. 31, 2024, and 300 MW
through Dec. 31, 2025. The contract is designated as an all-in-one cash flow hedge.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">For periods beyond March 2019, market forward
power prices are not readily observable. For these periods, fundamental-based forecasts and market indications have been used to
determine proxies for base, high, and low power price scenarios. The base price forecast has been developed by averaging external
fundamental based forecasts (providers are independent and widely accepted as industry experts for scenario and planning views).
Forward power price ranges per Megawatt hour (&ldquo;MWh&rdquo;) used in determining the Level III base fair value at March 31,
2017 are US$26 - US$36 (Dec. 31, 2016 - US$27 - US$36). <FONT STYLE="color: black">The sensitivity analysis has been prepared using

power prices are not readily observable. For these periods, fundamental-based price forecasts and market indications have been
used as proxies to determine base, high, and low power price scenarios. The base scenario uses the most recent price view from
an independent external forecasting service that is accepted within industry as an expert in the Alberta market. Forward power
price ranges per MWh used in determining the Level III base fair value at March 31, 2017 are $67 - $82 (Dec. 31, 2016 - $68 - $93). <FONT STYLE="color: black">The sensitivity analysis for both periods

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Under the unit contingent power purchase
agreements, the Corporation has agreed to purchase power contingent upon the actual generation of specific units owned and operated
by third parties. Under these types of agreements, the purchaser pays the supplier an agreed upon fixed price per MWh of output
multiplied by the pro rata share of actual unit production (nil if a plant outage occurs). The contracts are accounted for as held
for trading.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The key unobservable inputs used in the
valuations are delivered volume expectations and hourly shapes of production. Hourly shaping of the production will result in realized
prices that may be at a discount (or premium) relative to the average settled power price. Reasonably possible alternative inputs
were used to determine sensitivity on the fair value measurements.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">This analysis is based on historical production
data of the generation units for available history. Price and volumetric discount ranges per MWh used in the Level III base fair
value measurement at March 31, 2017 are nil (Dec. 31, 2016 &ndash; nil) and 2.15 per cent to 3.54 per cent (Dec. 31, 2016 &ndash;
2.15 per cent to 3.62 per cent), respectively. <FONT STYLE="color: black">The sensitivity analysis has been prepared using the
Corporation&rsquo;s assessment of a reasonably possible change in price discount ranges of approximately 0.73 per cent (Dec. 31,
2016 &ndash; 0.75 per cent) and a change in volumetric discount rates of approximately 8.6 per cent (Dec. 31, 2016 &ndash; 15.5

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Corporation has fixed priced power
and heat rate contracts in the eastern United States. Under the fixed priced power contracts, the Corporation has agreed to buy
or sell power at non-liquid locations, or during non-standard hours. The Corporation has also bought and sold heat rate contracts
at both liquid and non-liquid locations. Under a heat rate contract, the buyer has the right to purchase power at times when the
market heat rate is higher than the contractual heat rate.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The key unobservable inputs in the valuation
of the fixed priced power contracts are market forward spreads and non-standard shape factors. A historical regression analysis
has been performed to model the spreads between non-liquid and liquid hubs. The non-standard shape factors have been determined
using the historical data. Basis relationship and non-standard shape factors used in the Level III base fair value measurement
at March 31, 2017, are 68 per cent to 120 per cent and 68 per cent to 88 per cent (Dec. 31, 2016 &ndash; 66 per cent to 128 per
cent and 65 per cent to 88 per cent), respectively. The sensitivity analysis has been prepared using the Corporation&rsquo;s assessment
of a reasonably possible change in market forward spreads of approximately 5 per cent (Dec. 31, 2016 &ndash; 5 per cent) and a
change in non-standard shape factors of approximately 7 per cent (Dec. 31, 2016 &ndash; 9 per cent), which approximate one standard
deviation for each input.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The key unobservable inputs in the valuation
of the heat rate contracts are implied volatilities and correlations. Implied volatilities and correlations used in the Level III
base fair value measurement at March 31, 2017 are 20 per cent to 51 per cent and 70 per cent (Dec. 31, 2016 &ndash; 20 per cent
to 54 per cent and 70 per cent), respectively. The sensitivity analysis has been prepared using the Corporation&rsquo;s assessment
of a reasonably possible change in implied volatilities and correlation of approximately 10 per cent (Dec. 31, 2016 &ndash; 10
per cent), respectively.</P>

discontinued hedge accounting for certain foreign currency cash flow and fair value hedges on US$690 million and US$50 million

Corporation are based on adjusted quoted prices on an active exchange or extend beyond the time period for which exchange-based
quotes are available. The fair values of these derivatives are determined using inputs that are not readily observable. Refer to
section B of this note for fair value Level III valuation techniques used. In some instances, a difference may arise between the
fair value of a financial instrument at initial recognition (the &ldquo;transaction price&rdquo;) and the amount calculated through
a valuation model. This unrealized gain or loss at inception is recognized in net earnings (loss) only if the fair value of the
instrument is evidenced by a quoted market price in an active market, observable current market transactions that are substantially
the same, or a valuation technique that uses observable market inputs. Where these criteria are not met, the difference is deferred
on the Condensed Consolidated Statements of Financial Position in risk management assets or liabilities, and is recognized in net
earnings (loss) over the term of the related contract. The difference between the transaction price and the fair value determined
using a valuation model, yet to be recognized in net earnings, and a reconciliation of changes is as follows:</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The following discussion is limited to
the nature and extent of certain risks arising from financial instruments, which are also more fully discussed in Note 14(b) of
the Corporation&rsquo;s most recent annual consolidated financial statements.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><B>&nbsp;</B></P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Corporation has exposure to movements
in certain commodity prices in both its electricity generation and proprietary trading businesses, including the market price of
electricity and fuels used to produce electricity. Most of the Corporation&rsquo;s electricity generation and related fuel supply
contracts are considered to be contracts for delivery or receipt of a non-financial item in accordance with the Corporation&rsquo;s
expected own use requirements and are not considered to be financial instruments. As such, the discussion related to commodity
price risk is limited to the Corporation&rsquo;s proprietary trading business and commodity derivatives used in hedging relationships
associated with the Corporation&rsquo;s electricity generating activities.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify"><B>&nbsp;</B></P>

<P STYLE="font: italic 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left">i. Commodity Price Risk &ndash; Proprietary
Trading</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Corporation&rsquo;s Energy Marketing
segment conducts proprietary trading activities and uses a variety of instruments to manage risk, earn trading revenue, and gain
market information.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">In compliance with the Commodity Exposure
Management Policy, proprietary trading activities are subject to limits and controls, including Value at Risk (&ldquo;VaR&rdquo;)
limits. The Board approves the limit for total VaR from proprietary trading activities. VaR is the most commonly used metric employed
to track and manage the market risk associated with trading positions. A VaR measure gives, for a specific confidence level, an
estimated maximum pre-tax loss that could be incurred over a specified period of time. VaR is used to determine the potential change
in value of the Corporation&rsquo;s proprietary trading portfolio, over a three-day period within a 95 per cent confidence level,
resulting from normal market fluctuations. VaR is estimated using the historical variance/covariance approach.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Changes in market prices associated with
proprietary trading activities affect net earnings in the period that the price changes occur. VaR at March 31, 2017, associated
with the Corporation&rsquo;s proprietary trading activities was $1 million (Dec. 31, 2016 - $2 million).</P>

<P STYLE="font: italic 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left">ii. Commodity Price Risk - Generation</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The generation segments utilize various
commodity contracts to manage the commodity price risk associated with electricity generation, fuel purchases, emissions, and byproducts,
as considered appropriate. A Commodity Exposure Management Policy is prepared and approved annually, which outlines the intended
hedging strategies associated with the Corporation&rsquo;s generation assets and related commodity price risks. Controls also include
restrictions on authorized instruments, management reviews on individual portfolios, and approval of asset transactions that could
add potential volatility to the Corporation&rsquo;s reported net earnings.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">TransAlta has entered into various contracts
with other parties whereby the other parties have agreed to pay a fixed price for electricity to TransAlta. While not all of the
contracts create an obligation for the physical delivery of electricity to other parties, the Corporation has the intention and
believes it has sufficient electrical generation available to satisfy these contracts and, where able, has designated these as
cash flow hedges for accounting purposes.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">VaR at March 31, 2017, associated with
the Corporation&rsquo;s commodity derivative instruments used in generation hedging activities was $17 million (Dec. 31, 2016 -
$19 million). For positions and economic hedges that do not meet hedge accounting requirements or for short-term optimization transactions
such as buybacks entered into to offset existing hedge positions, these transactions are marked to the market value with changes
in market prices associated with these transactions affecting net earnings in the period in which the price change occurs. VaR
at March 31, 2017, associated with these transactions was $3 million (Dec. 31, 2016 - $7 million).</P>

currencies, such as the U.S. dollar, and the Australian dollar (&ldquo;AUD&rdquo;), as a result of investments and operations in
foreign jurisdictions, the net earnings from those operations, and the acquisition of equipment and services from foreign suppliers.
Further discussion on Currency Rate Risk can be found in Note 14(B)(I)(c) of the Corporation&rsquo;s most recent annual consolidated
financial statements.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left">II. Credit Risk</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Credit risk is the risk that customers
or counterparties will cause a financial loss for the Corporation by failing to discharge their obligations, and the risk to the
Corporation associated with changes in creditworthiness of entities with which commercial exposures exist. The Corporation actively
manages its exposure to credit risk by assessing the ability of counterparties to fulfil their obligations under the related contracts
prior to entering into such contracts. The Corporation makes detailed assessments of the credit quality of all counterparties and,
where appropriate, obtains corporate guarantees, cash collateral, third-party credit insurance, and/or letters of credit to support
the ultimate collection of these receivables. For commodity trading and origination, the Corporation sets strict credit limits
for each counterparty and monitors exposures on a daily basis. TransAlta uses standard agreements that allow for the netting of
exposures and often include margining provisions. If credit limits are exceeded, TransAlta will request collateral from the counterparty
or halt trading activities with the counterparty.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Corporation uses external credit ratings,
as well as internal ratings in circumstances where external ratings are not available, to establish credit limits for customers
and counterparties. The following table outlines the Corporation&rsquo;s maximum exposure to credit risk without taking into account
collateral held, including the distribution of credit ratings, as at March 31, 2017:</P>

restrictions include the ability to meet a debt service coverage ratio prior to distribution, which was not met by one of the Corporation&rsquo;s
subsidiaries, New Richmond Wind L.P. in the first quarter of 2017, mainly due to annualization of its results for purposes of the
test. The funds in this entity will remain there until the next debt service coverage ratio can be calculated in the second quarter

extended and revised its existing agreement with Alstom to provide major maintenance for the Corporation&rsquo;s Canadian Coal
facilities. The agreement relates to major maintenance projects over the 2017 through 2020 years at the Corporation&rsquo;s Keephills
plants and on some Sundance plants. Alstom will be accountable for providing its services on budget and on time with a guarantee
on performance.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">TransAlta is occasionally named as a party
in various claims and legal and regulatory proceedings that arise during the normal course of its business. TransAlta reviews each
of these claims, including the nature of the claim, the amount in dispute or claimed, and the availability of insurance coverage.
There can be no assurance that any particular claim will be resolved in the Corporation&rsquo;s favour or that such claims may
not have a material adverse effect on TransAlta. Inquiries from regulatory bodies may also arise in the normal course of business,
to which the Corporation responds as required.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left">I. Line Loss Rule Proceeding</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The Corporation is participating in a line
loss rule proceeding (the &quot;LLRP&quot;) that is currently before the Alberta Utilities Commission (&ldquo;AUC&rdquo;).&nbsp;
The AUC determined that it had the ability to retroactively adjust line loss rates going back to 2006 and directed the Alberta
Electric System Operator (the &quot;AESO&quot;) to, among other things, perform such retroactive calculations.&nbsp; The various
decisions by the AUC are, however, subject to appeal and challenge. &nbsp;The Corporation may incur additional transmission charges
as a result of the LLRP.&nbsp; The outcome of the LLRP, however, currently remains uncertain and the total potential exposure faced
by the Corporation, if any, cannot be calculated with certainty until retroactive calculations using a AUC-approved methodology
are made available, and until the AUC determines what methodology will be used for retroactive calculations.&nbsp; The AESO expects
retroactive calculations for each year using a AUC-approved methodology to begin to be available in the second quarter of 2017,
at the earliest.&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">An additional IFRS measure is a line item,
heading, or subtotal that is relevant to an understanding of the financial statements but is not a minimum line item mandated
under IFRS, or the presentation of a financial measure that is relevant to an understanding of the financial statements but is
not presented elsewhere in the financial statements. We have included line items entitled gross margin and operating income (loss)
in our Condensed Consolidated Statements of Earnings (Loss) for the three months ended March 31, 2017, and 2016. Presenting these
line items provides management and investors with a measurement of ongoing operating performance that is readily comparable from
period to period.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We evaluate our performance and the performance
of our business segments using a variety of measures. Certain of the financial measures discussed in this MD&amp;A are not defined
under IFRS and, therefore, should not be considered in isolation or as an alternative to or to be more meaningful than net earnings
attributable to common shareholders or cash flow from operating activities, as determined in accordance with IFRS, when assessing
our financial performance or liquidity. These measures may not be comparable to similar measures presented by other issuers and
should not be considered in isolation or as a substitute for measures prepared in accordance with IFRS. Earnings before interest,
taxes, depreciation, and amortization (&ldquo;EBITDA&rdquo;), comparable EBITDA, Funds from Operations (&ldquo;FFO&rdquo;), and
&ldquo;Free Cash Flow&rdquo; (&ldquo;FCF&rdquo;) are Non-IFRS Measures. See the Reconciliation of Non-IFRS Measures and, Discussion

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0in">For the first quarter
of 2017, comparable EBITDA was $274 million, down $5 million compared with last year. As we were expecting, gross margin at Canadian
Coal was impacted by hedges rolling off and being replaced with lower priced hedges and by higher mining costs. 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 (&ldquo;OEFC&rdquo;) relating to the Ottawa and Windsor generating facilities totalling $34 million, almost fully
offset the shortfall in Energy Marketing and Canadian Coal.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0in">FFO and FCF were slightly
higher than last year as lower comparable EBITDA was offset by higher realized foreign exchange gains and non-cash mark-to-market
gains in 2017.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0in">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 shareholders. Last year net earnings
in the first quarter was 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.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">The decrease of $244 million in net debt
is primarily due to strong free cash flows, a decrease in our working capital, the receipt of $61 million from the sale of the
Wintering Hills merchant wind facility, and the impact of the weakening US dollar.</P>

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&rsquo;s Independent Electricity System Operator (&ldquo;IESO&rdquo;). We continue to receive monthly capacity payments

a proxy for the amount of cash generated from operating activities before changes in working capital, and provides the ability
to evaluate cash flow trends more readily in comparison with results from prior periods. FCF is an important metric as it represents
the amount of cash generated by our business, before changes in working capital, that is available to invest in growth initiatives,
make scheduled principal repayments on debt, repay maturing debt, pay common share dividends, or repurchase common shares. Changes
in working capital are excluded so as to not distort FFO and FCF with changes that we consider temporary in nature, reflecting,
among other things, the impact of seasonal factors and the timing of capital projects. FFO per share and FCF per share are calculated
using the weighted average number of common shares outstanding during the period.</P>

payment we received under the contracts as a capacity payment in our revenues instead of as finance lease income and a decrease
in finance lease receivables. We depreciate these assets over their expected lives. ii) We also reclassify the deprecation on

our existing arrangement with the IESO relating to our Mississauga cogeneration facility in Ontario and entered into a new Non-Utility
Generator (&ldquo;NUG&rdquo;) Contract effective Jan. 1, 2017. Under the new NUG Contract, we receive fixed monthly payments until
December 31, 2018 with no delivery obligations. Under IFRS in 2016, as a result of the NUG Contract, we recognized a receivable
of $207 million (discounted), a pre-tax gain of approximately $191 million net of costs to mothball the units, and accelerated
depreciation of $46 million. In 2017 and 2018, on a comparable basis, we record the payments we receive as revenues as a proxy
for operating income, and continue to depreciate the facility until Dec. 31, 2018.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify; text-indent: 0in">Comparable EBITDA for
the quarter totaled $274 million, down $5 million compared to last year. Even though prices in Alberta improved slightly compared
to last year, the rolling off of higher priced hedges negatively impacted the results of our Canadian Coal portfolio. Also, as
expected, we are facing higher coal costs in Alberta in 2017 due to an outage on one of our draglines at the mine, as well as
a higher strip ratio. Our strip ratio is expected to improve as we open a new mining area in 2018. Higher levels of rainfall in
the Pacific Northwest, coupled with a warmer winter in the Northeast, negatively impacted our ability to generate gross margins
in our Energy Marketing business. These shortfalls in Canadian Coal and Energy Marketing were mostly offset by the expected settlement
of the indexation dispute with the OEFC relating to the long-term contracts for the Ottawa and Windsor facilities.</P>

was up by $12 million, compared to 2016, due to higher realized foreign exchange gains, higher unrealized mark-to-market gains
and, lower sustaining capital expenditures, offset by higher distributions paid to subsidiaries&rsquo; non-controlling interests
as a result of the expected settlement of the indexation dispute for our long-term contracts at Ottawa and Windsor, which forms
part of TransAlta Cogeneration L.P (&ldquo;TA Cogen&rdquo;).</P>

March 31, 2017 increased 146 GWh compared to 2016. Lower availability caused by higher unplanned outages and derates was offset
by lower paid curtailments on contracted assets and lower levels of economic dispatching on our non-contracted generation as a
result of slightly higher prices.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">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.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Depreciation increased mainly due to the
shortening of the useful lives of the Keephills 3 and Genesee 3 facilities and on mine equipment at the Sunhills Mine. See the

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.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Availability for the three months ended
March 31, 2017 was down compared to 2016, due to a forced outage on Unit 1 in January. Both Units 1 and 2 commenced economic dispatching
in February as a result of seasonally lower prices in the Pacific Northwest. The lower availability had a nominal impact on our
results, as due to the low prices, contractual obligations were supplied by buying less expensive power in the market.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Production was up 440 GWh during the first
quarter of 2017 compared to 2016, due mainly to the timing of economic dispatching in 2017.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">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.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Depreciation and amortization for the
first quarter of 2017 increased by $18 million compared to 2016, due to an adjustment in 2016 on our future obligation caused
by higher discount rates being applied to our decommissioning obligation for the Centralia mine. As the mine is in the reclamation
stage, the adjustment flows directly to earnings. This adjustment reversed in the second quarter of 2016.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Production for the first quarter of 2017
decreased 306 GWh compared to 2016, primarily due to the Windsor and Mississauga plant recontracting. The Windsor facility has
been operating under a new capacity contract effective Dec. 1, 2016, and the Mississauga plant facility has been temporarily shut
down effective Jan. 1, 2017, as we have no delivery obligations under the new NUG Contract.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">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 Cogen.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Production for the first quarter of 2017
decreased by 76 GWh compared to 2016, mainly due to lower wind resources impacting generation across Western Canada and the sale
of the Wintering Hills merchant facility on March 1, 2017. This was partially offset by higher wind resources in Eastern Canada
and in the US.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Comparable EBITDA for the first quarter
of 2017 increased $7 million compared to 2016, primarily due to the sale of Solar Renewable Energy Credits (&ldquo;SRECs&rdquo;)
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 in 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 are slightly better prices in Alberta
on our non-contracted generation and indexation of our contracts in Eastern Canada.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Depreciation and amortization was lower
by $3 million in the first quarter of 2017 compared to 2016, due to the disposition of our Wintering Hills merchant wind facility,
which closed on March 1, 2017.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Our total capital commitment for the coal-to-gas
conversions is expected to be approximately $300 million, mostly invested between 2021 to 2023. We anticipate funding the conversions
with free cash flow at that time. These units are expected to provide low cost capacity and to be competitive in the upcoming
capacity market auctions; we expect the first auction to occur in 2019 for 2021 and that Federal and Provincial regulations will
be adopted to facilitate coal-to-gas conversions. We continue to be engaged with government in the development of the required
regulatory regime.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Under the terms of the OCA, we will receive
annual cash payments on or before July 31 of approximately $39.9 million ($37.4 million, net to the Corporation), commencing Jan.
1, 2017 and terminating at the end of 2030.&nbsp; We recognize the OCA payments evenly throughout the year. Accordingly, during
the three months ended March 31, 2017, approximately $10 million was recognized in Net Other Operating Income in the Condensed
Consolidated Statement of Earnings. Receipt of the payments is subject to certain terms and conditions. The OCA&rsquo;s main condition
is the cessation of all coal-fired emissions on or before Dec. 31, 2030. The affected plants are not, however, precluded from
generating electricity at any time by any method, other than the combustion of coal.</P>

we have approximately $2.5 billion of recourse and non-recourse debt maturing. We expect to refinance some of these upcoming debt
maturities by raising $700 million to $900 million of debt secured by our contracted cash flows over the next 12 to 15 months.
We also expect to continue our deleveraging strategy, as a significant part of our FCF over the next four years will be allocated
to debt reduction.</P>

of which $1.4 billion (Dec. 31, 2016 - $1.4 billion) was available for use. We are in compliance with the terms of the credit
facilities. At March 31, 2017, the $0.6 billion (Dec. 31, 2016 - $0.6 billion) of credit utilized under these facilities was comprised
of actual drawings of nil (Dec. 31, 2016 - nil) and letters of credit of $0.6 billion (Dec. 31, 2016 - $0.6 billion). These facilities
are comprised of a $1.5 billion committed syndicated bank facility expiring in 2020, one bilateral credit facility of US$200 million,

in total (Dec. 31, 2016 - $845 million) is subject to customary financing restrictions that restrict the Corporation&rsquo;s ability
to access funds generated by certain facilities&rsquo; operations. Upon meeting certain distribution tests, typically performed
once per quarter, the funds are able to be distributed by the subsidiary entities to their respective parent entity.&nbsp; These
restrictions include the ability to meet a debt service coverage ratio prior to distribution. This test was not met by one of
our subsidiaries, New Richmond Wind L.P. in the first quarter of 2017, mainly due to annualization of its results for purposes
of the test. The funds in this entity will remain there until the next debt service coverage ratio can be calculated in the second
quarter of 2017. At March 31, 2017, $44 million (Dec. 31, 2016 - $24 million) of cash was subject to these financial restrictions.</P>

require that certain reserve accounts are established and funded through cash held on deposit and/or by providing letters of credit.
As part of our cost reduction initiatives to reduce fees associated with letters of credit, we have elected to fund through cash.
Accordingly, as at March 31, 2017, $16 million of cash was on deposit for certain reserves and was not available for general use.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">TransAlta is participating in a line loss
rule proceeding (the &quot;LLRP&quot;) that is currently before the Alberta Utilities Commission (&ldquo;AUC&rdquo;).&nbsp; The
AUC has determined that it has the ability to retroactively adjust line loss rates going back to 2006 and directed the Alberta
Electric System Operator (the &quot;AESO&quot;) to, among other things, perform such retroactive calculations.&nbsp; The various
decisions by the AUC are, however, subject to appeal and challenge. &nbsp;TransAlta may incur additional transmission charges
as a result of the LLRP.&nbsp; The outcome of the LLRP, however, currently remains uncertain and the total potential exposure
faced by TransAlta, if any, cannot be calculated with certainty until retroactive calculations using an AUC-approved methodology
are made available, and until the AUC determines what methodology will be used for retroactive calculations.&nbsp; The AESO expects
retroactive calculations for each year using an AUC-approved methodology to begin to be available in the second quarter of 2017,
at the earliest.&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">As a result, no provision has been recorded

hedge accounting for certain foreign currency cash flow and fair value hedges on US$690 million and US$50 million of debt, respectively.
As at March 31, 2017, cumulative gains on the cash flow hedges of approximately $3 million will continue to be deferred in Accumulated
Other Comprehensive Income (&ldquo;AOCI&rdquo;) and will be reclassified to net earnings as the forecasted transactions (interest
payments) occur. As at March 31, 2017, cumulative losses of approximately $2 million related to the fair value hedge, and recognized
as part of the carrying value of the hedged debt, will be amortized to net earnings over the period to the debt&rsquo;s maturity.
Changes in these risk management assets and liabilities related to these discontinued hedge positions will be reflected within
net earnings prospectively.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We may enter into commodity transactions
involving non-standard features for which observable market data is not available. These are defined under IFRS as Level III financial
instruments. Level III financial instruments are not traded in an active market and fair value is, therefore, developed using
valuation models based upon internally developed assumptions or inputs. Our Level III fair values are determined using data such
as unit availability, transmission congestion, or demand profiles. Fair values are validated on a quarterly basis by using reasonably
possible alternative assumptions as inputs to valuation techniques, and any material differences are disclosed in the notes to
the financial statements.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">As at March 31, 2017, total Level
III financial instruments had a net asset carrying value of $784 million (Dec. 31, 2016 - $758 million net asset). The
increase during the period is primarily due to the changes in value of the long-term power sale contract designated as an
all-in-one cash flow hedge, for which changes in fair value are recognized in other comprehensive income.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left">Prices</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">For the remainder of 2017, power prices
in Alberta are expected to be slightly better than 2016 as a result of higher natural gas prices and incremental carbon costs
that increase the variable cost of generation year-over-year. However, prices can vary based on supply and weather conditions.
In the Pacific Northwest, power prices will be lower for the second quarter due to a strong hydro season, however, for third and
fourth quarters, prices are expected to be comparable to 2016.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left">Contractual Profile</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">As a result of Alberta PPAs and long-term
contracts, approximately 80 per cent of our capacity is contracted over the next two years. With the announced closure of Sundance
Unit 1 and the mothballing of Sundance Unit 2, this level of contracted capacity is relatively stable until the end of 2020 when
the PPA&rsquo;s on our Alberta coal fleet end. More than half of our non-contracted generation is sold forward 12 to 18 months
ahead of time using short-term physical or financial contracts, such that on an aggregated portfolio basis, depending on market
conditions, we target being up to 90 per cent contracted for the upcoming calendar year. As at the end of the first quarter of
2017, approximately 86 per cent of our 2017 capacity was contracted. The average prices of our short-term physical and financial
contracts for 2017 are approximately $45 per MWh in Alberta and approximately US$45 per MWh in the Pacific Northwest.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Availability of our coal fleet is expected
to be at the low end of our range of 86 to 88 per cent in 2017. Availability of our other generating assets (gas, renewables) generally
exceeds 95 per cent.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: left">Fuel Costs</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">As disclosed previously, the cost to mine
coal at our Alberta mine is expected to increase due to a major outage of a dragline and a higher strip ratio in 2017. Seasonal
variations in coal costs at our Alberta mine are minimized through the application of standard costing. Coal costs for 2017, on
a standard cost per tonne basis, are expected to be approximately 12 per cent higher than 2016 unit costs. Results in the first
quarter were in line with our expectations. The development of Pit 9 in 2018 is expected to improve our strip ratio.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">In the Pacific Northwest, our U.S. Coal
mine, adjacent to our power plant, is in the reclamation stage. Fuel at U.S. Coal has been purchased primarily from external suppliers
in the Powder River Basin and delivered by rail. The delivered fuel cost will decrease slightly in 2017 primarily due to lower
transportation costs resulting from lower expected natural gas prices.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Most of our generation from gas is sold
under contract with pass-through provisions for fuel. For gas generation with no pass-through provision, we purchase natural gas
from third parties coincident with production, thereby minimizing our risk to changes in prices.</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">&nbsp;</P>

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">We closely monitor the risks associated
with changes in electricity and input fuel prices on our future operations and, where we consider it appropriate, use various
physical and financial instruments to hedge our assets and operations from such price risks.</P>

of fluctuations in the Canadian dollar against the US dollar and Australian dollar by offsetting foreign-denominated assets with

<P STYLE="font: 10pt Times New Roman, Times, Serif; margin: 0pt 0; text-align: justify">Our results are seasonal due to the nature
of the electricity market and related fuel costs. Higher maintenance costs are usually incurred in the spring and fall when electricity
prices are expected to be lower, as electricity prices generally increase in the peak winter and summer months in our main markets
due to increased heating and cooling loads. Margins are also typically impacted in the second quarter due to the volume of hydro
production resulting from spring runoff and rainfall in the Pacific Northwest, which impacts production at U.S. Coal. Typically,
hydro facilities generate most of their electricity and revenues during the spring months when melting snow starts feeding watersheds
and rivers. Inversely, wind speeds are historically greater during the cold winter months and lower in the warm summer months.</P>
