I
have reviewed this annual report on Form 40-F of TransAlta Corporation;
2.
Based
on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements
made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;
3.
Based
on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the
financial condition, results of operations and cash flows of the issuer as of, and for, the periods presented in this report;
4.
The
issuer's other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in
Exchange Act Rules 13a-15(e) and 15d-15(e)) and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f)
and 15d-15(f)) for the issuer and have:
a)
Designed
such disclosure controls and procedures, or caused such disclosure controls and procedures to be designed under our supervision, to ensure that
material information relating to the issuer, including its consolidated subsidiaries, is made known to us by others within those entities, particularly during the period in which this report is
being prepared;
b)
Designed
such internal control over financial reporting, or caused such internal control over financial reporting to be designed under our supervision, to
provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting
principles;
c)
Evaluated
the effectiveness of the issuer's disclosure controls and procedures and presented in this report our conclusions about the effectiveness of the
disclosure controls and procedures, as of the end of the period covered by this report based on such evaluation; and
d)
Disclosed
in this report any change in the issuer's internal control over financial reporting that occurred during the period covered by the annual report
that has materially affected, or is reasonably likely to materially affect, the issuer's internal control over financial reporting; and
5.
The
issuer's other certifying officer(s) and I have disclosed, based on our most recent evaluation of internal control over financial reporting, to the
issuer's auditors and the audit committee of the issuer's board of directors (or persons performing the equivalent functions):
a)
All
significant deficiencies and material weaknesses in the design or operation of internal control over financial reporting which are reasonably likely to
adversely affect the issuer's ability to record, process, summarize and report financial information; and
b)
Any
fraud, whether or not material, that involves management or other employees who have a significant role in the issuer's internal control over financial
reporting.
