<P STYLE="font: bold 24pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">TransAlta Updates Shareholders on Hearing
Process</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">CALGARY, April 15, 2019 /CNW/ - TransAlta Corporation
(&quot;TransAlta&quot; or the &quot;Company&quot;) (TSX: TA) (NYSE: TAC) today updated shareholders regarding the private proceedings
sought to be commenced by dissident shareholder Mangrove Partners before the Ontario Securities Commission (&quot;OSC&quot;) and
Alberta Securities Commission (&quot;ASC&quot;).</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">This morning, the OSC heard submissions from
the parties on whether it should remain involved in these proceedings, or whether it should defer to the ASC as TransAlta's principal
regulator.&nbsp; The OSC elected to decline to assert jurisdiction and will not be involved in these proceedings any further.</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">The next step in the proceedings is for Mangrove
to seek leave (i.e., permission) from the ASC to pursue its complaints against TransAlta. The ASC will consider Mangrove's request
for leave this week, with an oral decision scheduled to be issued by the ASC on April 18, 2019, at 3:00 pm MT in Calgary, Alberta.&nbsp;</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">TransAlta will oppose Mangrove's efforts to
obtain leave and, if leave is granted, will vigorously contest the merits of Mangrove's complaints. It is important for shareholders
to understand that these proceedings have not been commenced by staff of the ASC or OSC but are private proceedings sought to be
pursued by Mangrove.&nbsp;&nbsp;&nbsp;</P>

<P STYLE="font: 15pt Arial, Helvetica, Sans-Serif; margin-right: 0; margin-left: 0">TransAlta's annual and special shareholders'
meeting will proceed on April 26, 2019 in Calgary, Alberta.</P>

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