to Securities Regulator</P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">CALGARY, April 17, 2019 /CNW/ - TransAlta Corporation
(&quot;TransAlta&quot; or the &quot;Company&quot;) (TSX: TA) (NYSE: TAC) announced today that Mangrove Partners has withdrawn its
application before the Alberta Securities Commission (&quot;ASC&quot;) for a hearing related to TransAlta's recent transaction
with Brookfield.</P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">As previously released, Mangrove originally
filed applications on April 8, 2019 before both the ASC and the Ontario Securities Commission (&quot;OSC&quot;) complaining about
the Brookfield transaction.&nbsp; On April 15, 2019, the OSC issued a decision declining to assert jurisdiction, which left the
matter solely within the jurisdiction of the ASC.</P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">Within hours of receiving TransAlta's response
submissions on April 17, 2019, Mangrove withdrew its application effective immediately.&nbsp; The result is that Mangrove's application
before the ASC has been abandoned.&nbsp; The OSC's previous decision declining to hear the complaints, coupled with Mangrove abandoning
its application before the ASC, means that this matter before the Commissions is at an end.</P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">TransAlta's 2019 annual and special meeting
will take place on April 26, 2019 in Calgary, Alberta.</P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">As previously disclosed, TransAlta secured
a strategic partnership and $750 million financing with Brookfield Renewable which will enable TransAlta to advance its strategy.&nbsp;
TransAlta's strategy is focused on converting coal units to gas, investing in renewables and accelerating returns to shareholders.</P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0"><B>Vote the BLUE Proxy Today</B></P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">TransAlta asks shareholders to read the Company's
management proxy circular dated March 26, 2019 (the &quot;Circular&quot;) carefully and to vote the BLUE proxy FOR all 12 TransAlta
director nominees at our upcoming annual and special shareholders' meeting on April 26, 2019 (the &quot;Meeting&quot;). Shareholder
support is critical as we work to build a foundation for long-term, sustainable value creation as a leading clean energy company.</P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">A copy of the Circular can be downloaded from
the Company's SEDAR profile at www.sedar.com and the Company's EDGAR profile at www.sec.gov. The Circular is also available at
TransAlta's website.</P>

<P STYLE="font: 12pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">A vote FOR TransAlta's director nominees will
be a vote to realize the value of TransAlta's diverse and quality assets for decades to come, a vote for an experienced and engaged
Board and a vote to share in the upside of TransAlta. Becoming a voter is fast and easy. To support TransAlta's Board, vote only
your <B>BLUE</B> proxy or voting instruction form today.</P>

<I>This news release contains forward-looking statements and forward-looking information within the meaning of applicable securities
laws. The use of any of the words &quot;expect&quot;, &quot;anticipate&quot;, &quot;continue&quot;, &quot;estimate&quot;, &quot;may&quot;,
&quot;will&quot;, &quot;project&quot;, &quot;should&quot;, &quot;propose&quot;, &quot;plans&quot;, &quot;intends&quot; and similar
expressions are intended to identify forward-looking information or statements. More particularly, and without limitation, this
news release contains forward-looking statements and information relating to: the timing, business and anticipated outcomes at
the 2019 shareholders' meeting, including as a result of actions by Mangrove/Bluescape; the nature, timing and impact of existing
or potential legal actions or regulatory proceedings, including those initiated by Mangrove; the investment by Brookfield Renewable
Partners or its institutional partners (&quot;Brookfield&quot;) and expected benefits to the Company and its shareholders; the
ability of the investment to enhance the Company's financial position and to execute its strategy; the Company's strategy, plans
and priorities; the Company's relationship with Brookfield or its affiliates and other shareholders; and the expected timing, costs
and benefits of the strategic investment by and partnership with Brookfield or its affiliates. These statements are based on TransAlta's
belief and assumptions based on information available at the time the assumptions were made, including assumptions pertaining to:
the election of the Company's proposed director nominees and outcome of other items to be voted upon at the 2019 shareholders'
meeting; the Company's ability to successfully defend against existing or potential legal actions or regulatory proceedings; the
closing of the Brookfield investment occurring and other risks to the Brookfield investment not materializing; no significant changes
to regulatory, securities, credit or market environments; the anticipated Alberta capacity market framework in the future; our
ownership of or relationship with TransAlta Renewables Inc. not materially changing; the Alberta hydro assets achieving their anticipated
value, cash flows and adjusted EBITDA; the anticipated benefits and financial results generated on the coal-to-gas conversion and
the Company's other strategies; the Company's and Mangrove's/Bluescape's strategies and plans; no significant changes in applicable
laws; and risks associated with the impact of the Brookfield investment on the Company's shareholders, debtholders and credit ratings.
The forward-looking statements are subject to a number of risks and uncertainties that may cause actual performance, events or
results to differ materially from those contemplated by the forward-looking statements. Some of the factors that could cause such
differences include: the failure of any of the Company's director nominees to be elected at the shareholders' meeting; the failure
of the Company to obtain approval for other items of business at the shareholders' meeting; the failure of the Brookfield investment
to close; the outcomes of existing or potential legal actions or regulatory proceedings not being as anticipated, including those
pertaining to the shareholders' meeting and the Brookfield investment; the impact of any withhold campaign or appointment of any
slate of directors proposed by Mangrove/Bluescape and the subsequent termination of the Brookfield investment by the Company; changes
in our relationship with Brookfield; changes in our relationship with other shareholders; the Brookfield investment not resulting
in the expected benefits for the Company and its shareholders; and other risks and uncertainties contained in the Company's Management
Proxy Circular dated March 26, 2019 and its Annual Information Form and Management's Discussion and Analysis for the year ended
December 31, 2018, filed under the Company's profile with the Canadian securities regulators on <U>www.sedar.com</U> and the U.S.
Securities and Exchange Commission on <U>www.sec.gov</U>. Readers are cautioned not to place undue reliance on these forward-looking
statements or forward-looking information, which reflect TransAlta's expectations only as of the date of this news release. In
light of these risks, uncertainties and assumptions, the forward-looking statements might occur to a different extent or at a different
time than we have described, or might not occur at all. TransAlta disclaims any intention or obligation to update or revise these
forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.</I></P>
