On June 2, 2009,
FirstEnergy Corp. issued a Press Release which includes earnings guidance and

Exhibit 99.1.





Information
contained herein, including Exhibit 99.1, shall not be deemed filed for the
purposes of the Securities Exchange Act of 1934, nor shall such information and
Exhibit 99.1 be deemed incorporated by reference in any filing under the
Securities Act of 1933, except as shall be expressly set forth by specific
reference in such a filing.





The non-GAAP*
information presented in the Press Release should be considered in addition to,
and not as a substitute for, the most directly comparable financial measure

              Press Release

*This Form 8-K
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, or
is subject to adjustment that has 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 include declarations regarding management's
intents, beliefs and current expectations. These statements typically contain,
but are not limited to, the terms "anticipate," "potential," "expect,"
"believe," "estimate" and similar words. Forward-looking statements involve
estimates, assumptions, known and unknown risks, uncertainties and other factors
that may cause actual results, performance or achievements to be materially
different from any future results, performance or achievements expressed or
implied by such forward-looking statements. Actual results may differ materially
due to the speed and nature of increased competition in the electric utility
industry and legislative and regulatory changes affecting how generation rates
will be determined following the expiration of existing rate plans inPennsylvania, the impact
of the PUCO's regulatory process on the Ohio Companies associated with the
distribution rate case, the impact of the competitive generation procurement
process in Ohio, economic or weather conditions affecting future sales and
margins, changes in markets for energy services, changing energy and commodity
market prices and availability, 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,
other legislative and regulatory changes, revised environmental requirements,
including possible greenhouse gas emission regulations, the potential impacts of
the U.S. Court of Appeals' July 11, 2008 decision requiring revisions to the
CAIR rules and the scope of any laws, rules or regulations that may ultimately
take their place, the uncertainty of the timing and amounts of the capital
expenditures needed to, among other things, implement the AQC Plan (including
that such amounts could be higher than anticipated or that certain generating
units may need to be shut down) or levels of emission reductions related to the
Consent Decree resolving the NSR litigation or other potential regulatory
initiatives, adverse regulatory or legal decisions and outcomes (including, but
not limited to, the revocation of necessary licenses or operating permits and
oversight) by the NRC (including, but not limited to, the Demand for Information
issued to FENOC on May 14, 2007), Met-Ed's and Penelec's transmission service
charge filings with the PPUC, the continuing availability of generating units
and their ability to operate at or near full capacity, the ability to comply
with applicable state and federal reliability standards, the ability to
accomplish or realize anticipated benefits from strategic goals (including
employee workforce initiatives), the ability to improve electric commodity
margins and to experience growth in the distribution business, the changing
market conditions that could affect the value of assets held in FirstEnergy’s
nuclear decommissioning trusts, pension trusts and other trust funds, and cause
it to make additional contributions sooner, or in an amount that is larger than
currently anticipated, the ability to access the public securities and other
capital and credit markets in accordance with FirstEnergy’s financing plan and
the cost of such capital, changes in general economic conditions affecting the
Registrant, the state of the capital and credit markets affecting the
Registrant, interest rates and any actions taken by credit rating agencies that
could negatively affect FirstEnergy’s access to financing or its costs and
increase its requirements to post additional collateral to support outstanding
commodity positions, letters of credit and other financial guarantees, the
continuing decline of the national and regional economy and its impact on
FirstEnergy’s major industrial and commercial customers, issues concerning the
soundness of financial institutions and counterparties with which FirstEnergy
does business, and the risks and other factors discussed from time to time in
the Registrant’s SEC filings, and other similar factors. Dividends declared from
time to time on FirstEnergy’s common stock during any annual period may in the
aggregate vary from the indicated amounts due to circumstances considered by
FirstEnergy’s Board of Directors at the time of the actual declarations. The
foregoing review of factors should not be construed as exhaustive. New factors
emerge from time to time, and it is not possible for management to predict all
such factors, nor assess the impact of any such factor on FirstEnergy’s business
or the extent to which any factor, or combination of factors, may cause results
to differ materially from those contained in any forward-looking statements. 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.
