The public offering price of the Notes will also include accrued interest, if any, from November 7, 2012 to the date of delivery.
The Notes will not be listed on any securities exchange or quotation system and, consequently, there is no market through which these securities may be sold and
purchasers may not be able to resell securities purchased under this Prospectus Supplement.
THE NOTES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE UNITED STATES SECURITIES AND EXCHANGE COMMISSION (THE "SEC") OR
ANY UNITED STATES STATE SECURITIES COMMISSION NOR HAS THE SEC OR ANY UNITED STATES STATE SECURITIES COMMISSION PASSED UPON
THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS SUPPLEMENT OR THE ACCOMPANYING PROSPECTUS. ANY REPRESENTATION TO THE
CONTRARY IS A CRIMINAL OFFENSE.
This offering is made by a Canadian issuer that is permitted, under the multijurisdictional disclosure system adopted by the United States, to prepare this Prospectus
Supplement and the accompanying Prospectus in accordance with Canadian disclosure requirements. Prospective investors should be aware that such requirements are
different from those of the United States. The financial statements incorporated herein have been prepared in accordance with International Financial Reporting
Standards ("IFRS") as issued by the International Accounting Standards Board and they are subject to Canadian auditing and auditor independence standards. As a
result, such financial statements may not be comparable to financial statements of United States companies.
Prospective investors should be aware that the acquisition of the securities described in this Prospectus Supplement and the accompanying Prospectus may have tax
consequences both in the United States and Canada. Such tax consequences for investors who are resident in, or citizens of, the United States may not be described fully
in this Prospectus Supplement or the accompanying Prospectus. You should read the tax discussion under "Certain Income Tax Considerations".
The enforcement by investors of civil liabilities under United States federal securities laws may be affected adversely by the fact that we are incorporated and organized
under the laws of Canada, that most of our officers and directors are residents of Canada, that some or all of the underwriters or experts named in this Prospectus
Supplement are residents of Canada, and that a substantial portion of our assets and the assets of said persons are located outside the United States.
The earnings coverage ratio on long term debt for the twelve month period ended September 30, 2012 is less than one-to-one and, since the Corporation had a loss for
such period, the coverage ratio is negative. See "Earnings Coverage".
The Notes will be ready for delivery in book-entry form only through the facilities of The Depository Trust Company ("DTC") and its direct and indirect participants on or about
November 7, 2012.

IMPORTANT NOTICE ABOUT INFORMATION IN
THIS PROSPECTUS SUPPLEMENT AND THE ACCOMPANYING PROSPECTUS
This document is in two parts. The first part is this prospectus supplement (this "Prospectus Supplement"), which describes the specific terms of the senior notes we are

SPECIAL NOTE REGARDING FORWARD-LOOKING STATEMENTS
This Prospectus Supplement and the accompanying Prospectus contain both historical and forward-looking statements within the meaning of Section 27A of the United States
Securities Act of 1933, as amended (the "U.S. Securities Act"), and Section 21E of the United States Securities Exchange Act of 1934, as amended (the "U.S. Exchange Act").
All forward-looking statements are based on TransAlta's beliefs as well as assumptions based on information available at the time the assumption was made and on management's
experience and perception of historical trends, current conditions and expected further developments as well as other factors deemed appropriate in the circumstances. Forward-
looking statements are not facts, but only predictions and generally can be identified by the use of statements that include phrases such as "may", "will", "believe", "expect",
"anticipate", "intend", "plan", "foresee", "potential", "enable", "continue" or other comparable terminology. These statements are not guarantees of TransAlta's future performance
and are subject to risks, uncertainties and other important factors that could cause TransAlta's actual performance to be materially different from those projected.
With respect to forward-looking statements contained in this Prospectus Supplement, we have made assumptions regarding, among other things: our ability to close this
offering on a timely basis and on the terms expected; fulfillment by the underwriters of their obligations pursuant to the underwriting agreement; and that no event will occur which
would allow the underwriters to terminate their obligations under the underwriting agreement.
In particular, this Prospectus Supplement and the accompanying Prospectus contain forward-looking statements pertaining to the following: the anticipated closing of the
offering of the Notes and the use of the proceeds of the offering; expectations relating to the timing of the completion and commissioning of projects under development, including
uprates and major projects, and their attendant costs; our estimated spend on growth and sustaining capital and productivity projects; expectations in terms of the cost of operations,
capital spend, and maintenance, and the variability of those costs; the impact of certain hedges on future reported earnings and cash flows; expectations related to future earnings
and cash flow from operating and contracting activities; estimates of fuel supply and demand conditions and the costs of procuring fuel; our estimated spend on growth and
sustaining capital projects; expectations for demand for electricity in both the short-term and long-term, and the resulting impact on electricity prices; expectations in respect of
generation availability and production; expectations in terms of the cost of operations and maintenance, and the variability of those costs; expected financing of our capital
expenditures; expected governmental regulatory regimes and legislation and their expected impact on us, as well as the cost of complying with resulting regulations and laws; our
trading strategy and the risk involved in these strategies; estimates of future tax rates, future tax expense, and the adequacy of tax provisions; accounting estimates;

expectations for the outcome of existing or potential legal and contractual claims; expectations for the ability to access capital markets at reasonable terms; the impact of certain
hedges on future reported earnings; the estimated impact of changes in interest rates and the value of the Canadian dollar relative to the U.S. dollar; the monitoring of our exposure
to liquidity risk.
Factors that may adversely impact the Corporation's forward-looking statements include risks relating to: fluctuations in market prices and availability of fuel supplies
required to generate electricity and in the price of electricity; the regulatory and political environments in the jurisdictions in which the Corporation operates; environmental
requirements and changes in, or liabilities under, these requirements; changes in general economic conditions including interest rates; operational risks involving our facilities,
including unplanned outages at such facilities; disruptions in the transmission and distribution of electricity; effects of weather; disruptions in the source of fuels, water, or wind
required to operate the Corporation's facilities; natural disasters; the threat of terrorism and cyber-attacks; equipment failure; energy trading risks; industry risk and competition;
fluctuations in the value of foreign currencies and foreign political risks; need for additional financing; structural subordination of securities; counterparty credit risk; insurance
coverage; the Corporation's provision for income taxes; legal and contractual proceedings involving the Corporation; reliance on key personnel; labour relations matters; and
development projects and acquisitions.
Readers are urged to consider these factors carefully in evaluating the forward-looking statements and are cautioned not to place undue reliance on these forward-looking
statements. The forward-looking statements included in this document are made only as of the date hereof and the Corporation does not undertake to publicly update these forward-
looking statements to reflect new information, future events or otherwise, except as required by applicable laws. In light of these risks, uncertainties and assumptions, the forward-
looking events might occur to a different extent or at a different time than the Corporation has described or might not occur. The Corporation cannot assure you that projected results
or events will be achieved. The foregoing risk factors, among others, including risks relating to the nature of the Notes, are described in further detail under the heading "Risk
Factors" in this Prospectus Supplement and in the accompanying Prospectus and in the documents incorporated by reference into this Prospectus Supplement and the accompanying
Prospectus, including the Annual MD&A and the Annual Information Form (each as hereinafter defined).
