Item 9.   Regulation FD Disclosure

          On August 28, 2003,  FirstEnergy released the following information to
the investment community.

          FirstEnergy  has been the subject of extensive  press coverage  during
the past two  weeks,  often by media  reporters  who do not  normally  cover our
industry or  FirstEnergy.  Additionally,  we have received  calls from investors
regarding several common issues mentioned in the press. This letter will provide
additional clarity and perspective regarding these matters.

Second Quarter 2003 Cash From Operations
----------------------------------------

          Recent  media  stories  have  drawn  various   conclusions   regarding
FirstEnergy's  financial  status and liquidity  based on  information in our SEC
Form  10-Q  filing  for the  second  quarter  of 2003.  Net cash  provided  from
operating  activities was $22 million in the second  quarter of 2003,  down from
$262 million for the second  quarter of 2002.  For the six months ended June 30,
2003, cash provided from operating  activities was $484 million,  down from $726
million for the same period of 2002.

          These  reductions   primarily  result  from  the  challenges  that  we
discussed on our first and second quarter earnings conference calls. Shown below
is a summary  of the major  items  giving  rise to the  reductions  for the 2003
periods compared with the 2002 periods.

          Total reduction in cash from operations       $(240.4)      $(242.2)

          We have been asked about the  details of the  "other"  category in the
Statement of Cash Flows.  Attached to this letter is a schedule of the quarterly
Statements of Cash Flows from  year-end 2001 through the second  quarter of 2003
that provides additional detail of the "other" category.

          We have also been asked why the "other" category for the most recent
period was negative since it is usually a positive in prior quarters. You will
recall that the New Jersey Board of Public Utilities (BPU) decided Jersey
Central Power & Light Company's (JCP&L) base rate case on July 25, 2003. In that
ruling, the BPU disallowed the recovery of $152.5 million of

                                       1



deferred energy costs and $6 million of other costs. As a result,  we recorded a
$158.5  million  non-cash  charge to net income in the second quarter of 2003 to
recognize the  non-recoverability  of these items. Although that non-cash charge
is included in the "Deferred costs recoverable as regulatory assets" line on the
Statement  of Cash  Flows in the  second  quarter,  we  wanted to  provide  more
visibility of that amount given the size of the charge.  Therefore,  we included
an  additional  line item for the $158.5  million  disallowance  as  "Disallowed
regulatory assets" to provide that visibility and a corresponding $158.5 million
offset was included as a reduction in the "other" category.  Had we not isolated
that charge,  the "other"  category  would have been a positive $91.9 million in
the second quarter.

Cash Balances and Liquidity
---------------------------

          Some of  FirstEnergy's  media  coverage  during  the  past  two  weeks
erroneously  reported that the company was now facing "a cash crunch" due to its
second quarter  financial  statement's cash and cash  equivalents  balance being
only $64 million. As you know, a company's liquidity position is measured as the
sum of cash and unused credit facilities.  As reported in our second quarter SEC
Form  10-Q,  our  unused  credit  capacity  was $210  million,  producing  total
liquidity of $274 million. More importantly, on any given day, cash balances are
greatly influenced by financing and refinancing activities,  the timing of large
bill payments and cash receipts, and interest and dividend payments.

          For example,  much was made of  FirstEnergy's  cash balance being $360
million at the end of the second quarter of 2002, one year earlier.  On June 30,
2002,  JCP&L had just  completed an asset  securitization  transaction  and $240
million of  securitization  proceeds were being held in escrow awaiting drawdown
so the escrow funds inflated the cash balance on that day. A few days later, the
funds were  released from escrow and used to pay down  outstanding  debt and the
cash balance was similarly  reduced.  We manage our cash balance to minimize net
financing  costs  since  the  earnings  rate  on our  temporary  investments  is
typically less than our short-term borrowing costs.

          We recently  closed on a new $450 million  secured credit  facility at
Ohio  Edison.  This  facility  will expire at  year-end  and was put in place to
insure ample liquidity through the end of the year. Including this new facility,
our total  liquidity  was $933  million at the close of  business  on August 26,
2003.  We generally  target to have about $500 million of liquidity  recognizing
that on any given day,  we could be several  hundred  million  dollars  above or
below that  general  target  level.  Of course,  in addition to their  liquidity
resources,  the  FirstEnergy  companies have access to public debt and preferred
securities  markets and have the  capacity to issue  substantial  amounts of new
fixed income securities.

Equity Issuance
---------------

          As part of our  commitment  to  maintain  our  investment  grade  debt
ratings,  we are proceeding with the necessary steps to issue additional  shares
of common  stock.  We filed  yesterday  an amendment to our omnibus $2.0 billion
"shelf"  registration  statement  on Form S-3 with the SEC.  Once the  filing is
declared effective by the SEC and depending upon market conditions, we expect to
proceed in a timely manner to issue  additional  common equity and are generally
targeting a sale of $500 million to $750  million.  Net proceeds will be used to
reduce debt.

          The securities covered by the shelf registration  statement may not be
sold nor may  offers  to buy be  accepted  prior  to the  time the  registration
statement becomes effective. This letter does not constitute an offer to sell or
the  solicitation  of any  offer  to buy nor  shall  there  be any sale of these
securities  in any state in which  such  offer,  solicitation  or sale  would be
unlawful prior to registration or qualification under the securities laws of any
such state. When a written  prospectus meeting the requirements of Section 10 of
the Securities Act of 1933 with respect to any securities becomes available, you
may obtain a copy from  FirstEnergy  Corp., 76 South Main Street,  Akron,  Ohio,
44308.

Forecast for 2003
-----------------

          As  discussed  on our  second  quarter  earnings  call,  we  expect to
generate  about $575  million of free cash  during  2003,  which will be used to
retire  debt.  This amount  reflects  $370  million of free cash flow (cash flow

                                       2




after capital  expenditures  of about $733 million and common stock dividends of
$441 million) plus the $129 million cash benefit of the Emdersa abandonment, the
sale of our note  receivable  from Aquila to a third party for $62 million,  and
the expected $14 million  proceeds from the sale of Avon Energy  Partners.  This
positive cash flow is after  incurring  about $250 million of replacement  power
and  incremental O&M  expenditures at Davis-Besse  this year assuming a mid-fall
restart.

          Although  our free cash  generation  in 2003 is less than our original
projections,  it remains strongly  positive.  It is unfortunate that many recent
stories in the media based their conclusions regarding  FirstEnergy's  financial
status and liquidity  almost  exclusively  on several line items in our SEC Form
10-Q filing including the June 30, 2003 cash balance.

Forward-Looking  Statement:  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," "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,  maintenance  costs  being  higher  than  anticipated,  legislative  and
regulatory  changes  (including  revised  environmental  requirements),  adverse
regulatory or legal decisions,  availability  and cost of capital,  inability of
the  Davis-Besse  Nuclear  Power  Station to restart  (including  because of any
inability to obtain a favorable final  determination from the Nuclear Regulatory
Commission) in the fall of 2003,  inability to accomplish or realize anticipated
benefits of strategic goals, the ability to timely sell a significant  amount of
equity at an  acceptable  price,  the  ability to access  the public  securities
markets,  further  investigation  into the causes of the  August 14,  2003 power
outage and the outcome,  cost and other effects of present and  potential  legal
and  administrative  proceedings  and claims  related to that outage,  and other
similar factors. Our credit facilities contain customary  provisions,  including
conditions to borrowings that require  representations and warranties  regarding
the existence of material adverse changes in the business,  condition (financial
or  otherwise),  results of  operations  or  prospects  of  FirstEnergy  and its
consolidated  subsidiaries  taken as a whole, or legal  proceedings which have a
reasonable  possibility of having such an effect.  As has been widely  reported,
various  class  action suits have been filed or  announced  against  FirstEnergy
relating to our recent  financial  restatements and the August 14, 2003 regional
outage.  While we are still in the early stages of addressing  these matters and
we do not know what other actions may be brought against us in the future, we do
not believe that any of these current  matters  impact our ability to access our
various credit facilities.
