Exhibit 31.2

                                  Certification


I, Richard H. Marsh, certify that:

1.   I have reviewed this amended annual report on Form 10-K/A of FirstEnergy
     Corp., Ohio Edison Company, The Cleveland Electric Illuminating Company,
     The Toledo Edison Company, Pennsylvania Power Company, Jersey Central Power
     & Light Company, Metropolitan Edison Company and Pennsylvania Electric
     Company;

2.   Based on my knowledge, this annual 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 annual report;

3.   Based on my knowledge, the financial statements, and other financial
     information included in this annual report, fairly present in all material
     respects the financial condition, results of operations and cash flows of
     each registrant as of, and for, the periods presented in this annual
     report;

4.   Each registrant's other certifying officer 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 such registrant and we
     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 such
               registrant,  including  its  consolidated  subsidiaries,  is made
               known to us by others within those entities,  particularly during
               the period in which this annual report is being prepared;

          b)   evaluated  the  effectiveness  of  such  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 such registrant's internal
               control  over  financial  reporting  that  occurred  during  such
               registrant's   most  recent  fiscal  year  that  has   materially
               affected,  or is  reasonably  likely to materially  affect,  such
               registrant's internal control over financial reporting; and

5.   Each registrant's other certifying officer and I have disclosed, based on
     our most recent evaluation of internal control over financial reporting, to
     such registrant's auditors and the audit committee of such registrant's
     board of directors (or persons performing the equivalent function):

          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 such registrant's
               ability to record, process,  summarize and report financial data;
               and

          b)   any fraud,  whether or not material,  that involves management or
               other employees who have a significant role in such  registrant's
               internal control over financial reporting.
