                             TXU ENERGY COMPANY LLC

                         of Sarbanes - Oxley Act of 2002
                              CERTIFICATION OF CEO

       I, Erle Nye, Chairman of the Board and Chief Executive of TXU Energy
Company LLC, certify that:

1.     I have reviewed this quarterly report on Form 10-Q of TXU
       Energy Company LLC;

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 registrant as of, and for,
       the periods presented in this report;

4.     The registrant'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)) for the registrant 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 registrant, 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.  Evaluated the effectiveness of the registrant'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

         c.  Disclosed in this report any change in the registrant's
             internal control over financial reporting that occurred during
             the registrant's most recent fiscal quarter (the registrant's
             fourth fiscal quarter in the case of an annual report) that
             has materially affected, or is reasonably likely to materially
             affect, the registrant's internal control over financial
             reporting; and

5.     The registrant's other certifying officer(s) and I have disclosed,
       based on our most recent evaluation of internal control over financial
       reporting, to the registrant's auditors and the audit committee of the
       registrant'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
             registrant'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
             registrant's internal control over financial reporting.
