                            CERTIFICATION OF CEO


 I, Erle Nye, Chairman of the Board and Chief Executive of Oncor Electric
Delivery Company, certify that:

1.   I have reviewed this quarterly report on Form 10-Q of Oncor Electric
     Delivery Company;

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.
