      May 3, 2007,
      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 a non-GAAP* financial
      measure. Pursuant to the requirements of Regulation G, FirstEnergy has provided
      a quantitative reconciliation within the Consolidated Report to the Financial
      Community of the non-GAAP* financial measure to the most directly comparable
      GAAP financial measure.</font></div>

      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
      "special items." Special items reflect the impact on earnings of events that
      are
      not routine or that may be related to discontinued businesses. 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 other companies in the
      energy sector. Management believes presenting this non-GAAP* measure provides
      useful information to investors in assessing FirstEnergy's normalized operating
      performance. FirstEnergy's management frequently references this non-GAAP*
      financial measure in its decision-making, using it to facilitate historical
      and
      ongoing performance comparisons as well as comparisons to the performance of
      peer companies.</font></div>

      2.02
      Results of Operations and Financial Condition
On
      May 3, 2007,
      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 a non-GAAP* financial
      measure. Pursuant to the requirements of Regulation G, FirstEnergy has provided
      a quantitative reconciliation within the Consolidated Report to the Financial
      Community of the non-GAAP* financial measure to the most directly comparable
      GAAP financial measure.
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
      "special items." Special items reflect the impact on earnings of events that
      are
      not routine or that may be related to discontinued businesses. 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 other companies in the
      energy sector. Management believes presenting this non-GAAP* measure provides
      useful information to investors in assessing FirstEnergy's normalized operating
      performance. FirstEnergy's management frequently references this non-GAAP*
      financial measure in its decision-making, using it 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, the most
      directly comparable financial measure prepared in accordance with
      GAAP. Also, the non-GAAP* financial measure may not be comparable to
      similarly titled measures used by other entities.

*This
      Form 8-K
      contains a non-GAAP financial measure. 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, or is subject to adjustment that have the effect of excluding or
      including 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.

Forward-Looking
      Statements:
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 and commodity market prices, replacement power
      costs being higher than anticipated or inadequately hedged, the continued
      ability of FirstEnergy's regulated utilities to collect transition and other
      charges or to recover increased transmission costs, maintenance costs being
      higher than anticipated, legislative and regulatory changes (including revised
      environmental requirements), and the legal and regulatory changes resulting
      from
      the implementation of the
Energy
      Policy Act of
      2005
(including,
      but not
      limited to, the repeal of the
Public
      Utility
      Holding Company Act of 1935
),
      the uncertainty
      of the timing and amounts of the capital expenditures needed to, among other
      things, implement the Air Quality Compliance Plan (including that such amounts
      could be higher than anticipated) or levels of emission reductions related
      to
      the Consent Decree resolving the New Source Review litigation, adverse
      regulatory or legal decisions and outcomes (including, but not limited to,
      the
      revocation of necessary licenses or operating permits and oversight) by the
Nuclear
      Regulatory Commission
and the various
      state public utility commissions as disclosed in the registrants'
Securities
      and
      Exchange Commission
filings, the timing
      and outcome of various proceedings before the
Public
      Utilities
      Commission of Ohio
(including, but not
      limited to, the successful resolution of the issues remanded to the
Public
      Utilities
      Commission of Ohio
by the Ohio Supreme
      Court regarding the Rate Stabilization Plan) and the
Pennsylvania
      Public
      Utility Commission
(including the
      transition rate plan filings for Met-Ed and Penelec and Penn's Default Service
      Plan filing), the continuing availability and operation of generating units,
      the
      ability of generating units to continue to operate at, or near full capacity,
      the inability to accomplish or realize anticipated benefits from strategic
      goals
      (including employee workforce initiatives), the anticipated benefits from
      voluntary pension plan contributions, the ability to improve electric commodity
      margins and to experience growth in the distribution business, the ability
      to
      access the public securities and other capital markets and the cost of such
      capital, the outcome, cost and other effects of present and potential legal
      and
      administrative proceedings and claims related to the August 14, 2003
      regional power outage, the successful structuring and completion of a potential
      sale and leaseback transaction for Bruce Mansfield Unit 1 currently under
      consideration by management, any purchase price adjustment under the accelerated
      share repurchase program announced March 2, 2007, the risks and other factors
      discussed from time to time in the registrants'
Securities
      and
      Exchange Commission
filings, and other
      similar factors. Also, a security rating is not a recommendation to buy, sell
      or
      hold securities, and it may be subject to revision or withdrawal at any time
      and
      each such rating should be evaluated independently of any other rating. The
      registrant expressly disclaims any current intention to update any
      forward-looking statements contained herein as a result of new information,
      future events, or otherwise.
