<P STYLE="font: bold 24pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">TransAlta Responds to Mangrove Application
for Joint Hearing</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">CALGARY, April 9, 2019 /CNW/ - TransAlta Corporation
(&quot;TransAlta&quot; or the &quot;Company&quot;) (TSX:TA) (NYSE:TAC)&nbsp;today announced that Mangrove Partners (&quot;Mangrove&quot;)
has made application to the Alberta Securities Commission and Ontario Securities Commission (together, the &quot;Commissions&quot;).
In the application, Mangrove is seeking a joint hearing of the Commissions in relation to TransAlta's 2019 annual and special meeting
of shareholders to be held on April 26, 2019 and the recently announced $750 million investment and strategic partnership with
an institutional partner of Brookfield Renewable Partners (&quot;Brookfield&quot;). Mangrove's application seeks various relief
from the Commissions, including an order cease trading the issuance of the exchangeable securities under the investment agreement
between the Company and Brookfield.</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">&quot;Mangrove's application is inappropriate,
unwarranted and without merit,&quot; said Ambassador Gordon Giffin, Chair of the Board of TransAlta. &quot;It is an attempt to
circumvent the rights of our other shareholders through a misuse of the Canadian securities regulatory process. We are moving forward
with our strategic partnership with Brookfield and the business of creating value for the Company's shareholders.&quot;</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0"><B>About TransAlta Corporation</B><BR>

the impact of the 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 the
Company's nominees to be elected at the 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 2019 meeting and
the Brookfield investment; the 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; our Alberta hydro assets not achieving their anticipated value, cash flows or adjusted EBITDA once the applicable
power purchase arrangement has expired; the Brookfield investment not resulting in the expected benefits for the Company and its
shareholders; the inability to complete share buy-backs within the timeline or on the terms anticipated or at all; 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 www.sedar.com and the Securities and Exchange Commission on www.sec.gov. Readers are cautioned not to

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>
