99.1             Press Release issued by FirstEnergy Corp., dated April 30, 2003
99.2             Consolidated Report to the Financial Community, dated
                 April 30, 2003


Item 9.  Regulation FD Disclosure

     The information in this Current Report on Form 8-K,  including the exhibits
listed above, is being furnished, not filed, under Item 9 pursuant to Regulation
FD and Item 12, "Disclosure of Results of Operations and Financial Condition" in
accordance  with SEC Release Nos. 33-8216 and 34-47583. The  information in this
report and in such  exhibits  shall not be  incorporated  by reference  into any
registration statement filed pursuit to the Securities Act of 1933, as amended.

     On April 30, 2003, FirstEnergy Corp. issued two public announcements, which
are attached as Exhibits 99.1 and 99.2 hereto and incorporated by reference.

     FirstEnergy's  Consolidated  Report  to the  Financial  Community  contains
non-GAAP  financial  measures.  Generally,  a  non-GAAP  financial  measure is a
numerical  measure of a company's  historical or future  financial  performance,
financial position,  or cash flows that either excludes or includes amounts that
are not normally  excluded or included in the most directly  comparable  measure
calculated  and presented in accordance  with  accounting  principles  generally
accepted  in the  United  States,  or  GAAP.  Pursuant  to the  requirements  of
Regulation G, FirstEnergy has provided quantitative  reconciliations  within the
Consolidated  Report  to  the  Financial  Community  of the  non-GAAP  financial
measures to the most directly comparable GAAP financial measures.

     The  Consolidated  Report to the Financial  Community  includes  normalized
earnings per share,  which is not calculated in accordance  with GAAP because it
excludes the impact of "unusual or one-time  items".  Unusual  items reflect the
impact on earnings of events that are not routine, are related to prior periods,
are related to discontinued businesses or the cumulative effect of an accounting
change.  Management believes  presenting  normalized earnings calculated in this
manner  provides  useful  information  to  investors in  evaluating  the ongoing
results of  FirstEnergy's  businesses  and assists  investors in  comparing  the
company's  operating  performance to the operating  performance of others in the
energy sector.  FirstEnergy's  management  frequently  references these non-GAAP
financial measures in its decision-making,  using them to facilitate  historical
and ongoing performance comparisons as well as comparisons to the performance of
peer companies.

     The  non-GAAP  information  presented  in the  Consolidated  Report  to the
Financial Community should be considered in addition to, and not as a substitute
for, reported earnings per share prepared in accordance with GAAP.

     This Form 8-K  includes  forward-looking  statements  based on  information
currently available to management.  Such statements are subject to certain risks
and uncertainties.  These statements  typically contain, but are not limited to,
the terms "anticipate," "potential," "expect," "believe," "estimate" and similar
words.  Actual  results  may  differ  materially  due to the speed and nature of
increased  competition  and  deregulation  in  the  electric  utility  industry,
economic or weather  conditions  affecting future sales and margins,  changes in
markets for energy  services,  changing  energy market prices,  legislative  and
regulatory changes (including revised environmental requirements),  availability
and cost of capital,  inability to accomplish or realize anticipated benefits of
strategic goals and other similar factors.
