                              CERTIFICATION OF CEO

         I, Paul O'Malley, Chairman of the Board, President 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.
