Regarding the Consultation Process Initiation</B></P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 9.75pt 0">CALGARY, July 5, 2017 /CNW/ -&nbsp;TransAlta Corporation (&quot;TransAlta&quot;
or the &quot;Company&quot;) (TSX: TA; NYSE: TAC) today issued the following comments on the Balancing Pool's recent announcement
to commence consultation with customer representatives and the Minister of Energy regarding its ability to terminate a subset of
the Alberta Power Purchase Arrangements (&quot;PPA&quot;) that it holds.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 9.75pt 0">&quot;The PPAs were a design of the initial deregulation of
the Alberta market in 2000. &nbsp;They were based on a regulated rate of return on low cost hydro and coal assets that have served
Albertans for well over 50 years,&quot; said TransAlta President and CEO Dawn Farrell. &quot;Shortening the life of the PPAs moves
the Alberta market more quickly to total deregulation of the electricity market. &nbsp;It's important that consumers, and other
stakeholders fully evaluate the impacts of such a change in advance of the new capacity market which isn't slated to start until
2021.&quot;</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 9.75pt 0">Under Part 6, Section 97 of the <I>Electric Utilities Act
</I>(Alberta), the Balancing Pool may terminate the PPAs if it:</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 9.75pt 0">TransAlta has 3,770 MW of gross capacity under PPAs, including
hydro, representing approximately 23% of the generation capacity in Alberta.&nbsp; If, after meeting the requirements, the Balancing
Pool chooses to terminate the Sundance PPAs, TransAlta expects to receive approximately $231 million in payment for the net book
value of the assets as compared to the Balancing Pool's estimate of approximately $171 million. The Balancing Pool's estimate differs
because it excludes certain assets which TransAlta believes should be included in the net book value.&nbsp; Proceeds from any termination
would be used to reduce outstanding debt and fund growth opportunities.</P>

<P STYLE="font: 10pt Arial, Helvetica, Sans-Serif; margin: 9.75pt 0">Termination of the PPAs is expected to provide TransAlta with
increased operational flexibility, including with respect to offer pricing for generation from the affected units, maintenance
and turnaround schedules, and the timing of the coal-to-gas conversions.</P>

This news release contains forward-looking statements within the meaning of applicable securities laws, including statements regarding:
the termination of the PPAs; the impact that the termination of the PPAs could have on the Alberta market; the net book value of
the Company's generating facilities and the amount of any termination payment; the use of proceeds received in connection with
any termination of the PPAs; and the impact the termination of the PPAs will have on the Company, including as it pertains to increasing
operational flexibility, including with respect to offer pricing for generation from the affected units, maintenance and turnaround
schedules and the timing of the coal-to-gas conversion. These statements are based on TransAlta's belief and assumptions based
on information available at the time the assumptions were made. These statements are subject to a number of risks and uncertainties
that may cause actual results to differ materially from those contemplated by the forward-looking statements. Some of the factors
that could cause such differences include: a delay in any termination of the PPAs by the Balancing Pool or a decision not to terminate
the PPAs by the Balancing Pool; a change in the net book value payable upon termination of the PPAs; legislative or regulatory
changes; and changes to power prices or operating costs. Readers are cautioned not to place undue reliance on these forward-looking
statements, which reflect TransAlta's expectations only as of the date of this news release. 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,
