                        Report of Independent Accountants


To the Participants and the
Savings Plan Committee


In our opinion, the accompanying statements of net assets available for plan
benefits and the related statements of changes in net assets available for plan
benefits present fairly, in all material respects, the net assets available for
plan benefits of the FirstEnergy Corp. Savings Plan (the "Plan") at December 30,
2001 and 2000, and the changes in net assets available for plan benefits for the
years then ended in conformity with accounting principles generally accepted in
the United States of America. These financial statements are the responsibility
of the Plan's management; our responsibility is to express an opinion on these
financial statements based on our audits. We conducted our audits of these
statements in accordance with auditing standards generally accepted in the
United States of America, which require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management, and
evaluating the overall financial statement presentation. We believe that our
audits provide a reasonable basis for our opinion.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedules of assets
(held at end of year) and reportable transactions are presented for the purpose
of additional analysis and are not a required part of the basic financial
statements but are supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. The supplemental schedules are the
responsibility of the Plan's management. These supplemental schedules have been
subjected to the auditing procedures applied in the audits of the basic
financial statements and, in our opinion, are fairly stated in all material
respects in relation to the basic financial statements taken as a whole.

FirstEnergy Corp. Savings Plan

Notes to Financial Statements
December 30, 2001 and 2000
--------------------------------------------------------------------------------

1.  Description of the Plan

    The FirstEnergy Corp. Savings Plan (the "Plan") provides eligible
    employees of FirstEnergy Corp. ("FirstEnergy" or "FE") and its
    subsidiaries, collectively referred to as the "Companies" a mechanism
    through which they can save and invest part of their income on a tax
    deferred basis at regular intervals. Additionally, the Companies may
    match employee contributions with shares of FirstEnergy common stock (see
    Note 7) held in the Employee Stock Ownership Plan ("ESOP"). Employees may
    invest their contributions in other investment options (the "Funds") and
    all contributions made to employees' accounts are fully and immediately
    vested in the Plan. The purpose of the Plan is to encourage employees to
    adopt a regular savings program and to provide additional security for
    retirement. The following is a brief description of the Plan and is
    provided for general information purposes only. Employees should refer to
    the Plan documents for more complete information.

    The Plan is a qualified profit-sharing plan under Section 401(a) of the
    Internal Revenue Code of 1954, as amended (the "Code"), and provides for
    salary reduction contributions under Section 401(k) of the Code. In
    general, plans established pursuant to Section 401(k) of the Code permit
    eligible employees to defer current federal and, subject to applicable
    laws, state and local income taxes on the portion of their current
    compensation represented by the amount of the salary reduction elected.
    The amounts, as elected by the employees, are contributed to the Plan by
    the Companies through payroll deductions.

    The Plan is subject to Title I of the Employee Retirement Income Security
    Act of 1974 ("ERISA") but not Title IV as it is an "individual account
    plan". Title I establishes reporting and disclosure requirements, minimum
    standards for participation, vesting and benefit accrual, prohibitions
    governing the conduct of fiduciaries and provides that ERISA pre-empts
    other federal, state and local statutes relating to employee benefits.
    The protective benefits of Title IV which relate to insuring pension
    benefits by the Pension Benefit Guaranty Corporation are not applicable
    to individual account plans.

    Every permanent FirstEnergy Corp. employee is eligible to become a
    participant in the Plan, herein referred to as employee or Participant
    immediately at commencement of employment.

    Employees may participate in one or more of the Funds through deferral of
    compensation. The choice of investments (except the Companies' matching
    contributions, which are in the form of FirstEnergy common stock) is the
    responsibility of the individual employee. Transfers between funds are
    the responsibility of the employee and may be made on a daily basis.

    Securities in the ESOP Account
    The ESOP purchased a total of 10,654,114 shares of Ohio Edison ("OE")
    common stock from November 1990 to December 1991 for the purpose of
    funding the Companies' matching contribution to the Plan. On November 8,
    1997, pursuant to the merger of OE and Centerior Energy Corporation that
    created FirstEnergy Corp. ("Merger"), shares of OE common stock were
    converted into shares of FirstEnergy common stock on a one-for-one basis.

    The Plan borrowed $200 million, referred to herein as the "ESOP Loan", at
    a rate of 10% from OE to fund the purchase of the stock. The ESOP Loan is
    collateralized by the unallocated FirstEnergy common stock acquired with
    the proceeds of the ESOP Loan. The ESOP Loan is expected to be

--------------------------------------------------------------------------------

    repaid by December 2005. Interest payments on the loan are made annually.
    Additionally, principal payments may be made sooner if additional shares
    of FirstEnergy common stock are needed for distributions to Participants.
    At December 30, 2001 and 2000, the ESOP Loan balance was $149,550,000 and
    $168,250,000, respectively.

    Requirements for maturing long-term debt are as follows:


          2002 .........    $ 23,700,000
          2003 .........      29,300,000
          2004 .........      35,700,000
          2005 .........      60,850,000
                            ------------

                            $149,550,000
                            ============


    ESOP Allocation
    As principal and interest payments are made on the ESOP Loan, shares of
    FirstEnergy common stock are released from the ESOP Unallocated Fund to
    the ESOP Allocated Fund where they are made available for contribution to
    Participants' accounts. The Plan made interest payments of $35,100,000 in
    2001 and $19,415,000 in 2000, which released 812,272 shares in 2001 and
    477,625 shares in 2000. In December 2001, a principal payment of
    $18,700,000 was made which led to the release of 442,343 shares. In
    December 2000, a principal payment of $14,500,000 was made which led to
    the release of 342,993 shares. In January 2000, a principal payment of
    $11,400,000 was made leading to the release of 269,664 shares.

    The Companies' matching contribution to each Participant's account is
    computed the Thursday following the end of each pay period based on the
    Companies' matching contribution percentages (see Note 7) and on the
    quoted market price of the FirstEnergy common stock when contributed.
    During 2001 and 2000, respectively, 548,888 and 618,381 ESOP shares were
    contributed to Participants' accounts. In 2001 and 2000, respectively,
    197,077 and 212,128 ESOP shares were realized related to the reinvestment
    of dividends on the ESOP shares.

    At December 30, 2001 and 2000, there were 4,561,340 and 5,815,955 shares
    respectively, held in the ESOP Unallocated Fund at market values of
    $159,555,675 and $183,566,080, respectively, and 4,540,151 and 3,951,907
    shares, respectively, held in the ESOP Allocated Fund at market values of
    $176,352,004 and $124,732,064. The market value of the ESOP common stock
    is measured by the quoted market price.

    PAYSOP
    A component of the Plan consists of a qualified payroll-based tax credit
    employee stock ownership plan (PAYSOP) under Section 401(a) and Section
    501(a) of the Code.

    Under the Economic Recovery Tax Act of 1981, effective January 1, 1983,
    tax credits were based upon eligible employee compensation. The
    regulation permitted the Companies to contribute to the Trust a maximum
    of one-half of one percent of the aggregate compensation of eligible
    employees and claim a tax credit on its consolidated federal income tax
    return equal to this amount. The amounts allocated to eligible employees
    were based upon the proportion of their wages and salaries (to a maximum
    of $100,000) to the wages and salaries of total employees for the year.

FirstEnergy Corp. Savings Plan

Notes to Financial Statements
December 30, 2001 and 2000
--------------------------------------------------------------------------------

    The Tax Reform Act of 1986 eliminated the PAYSOP tax credit with respect
    to compensation earned in 1987 or later years. As a result, the Companies
    have not contributed to the PAYSOP since the 1986 contribution other than
    for the reimbursement of PAYSOP administrative expenses.

    On November 8, 1997, pursuant to the Merger, shares of OE common stock
    held in the PAYSOP were converted into shares of FirstEnergy common stock
    on a one-for-one basis.

    Dividends are paid annually to Participants in the PAYSOP. The market
    value of the common stock in the PAYSOP is measured by the quoted market
    price. As of February 11, 2002, dividends will be payable quarterly to
    Participants and Participants will also have the option to reinvest
    dividends back into the PAYSOP Fund.

2.  Summary of Accounting Policies

    The financial statements have been prepared on the accrual basis of
    accounting.

    The Plan presents, in the Statements of Changes in Net Assets Available
    for Plan Benefits, the net appreciation (depreciation) in the fair value
    of its investments, which consists of realized gains or losses and
    unrealized appreciation or depreciation. All investment management fees
    are deducted from investment income.

    The preparation of financial statements in conformity with accounting
    principles generally accepted in the United States of America requires
    management to make estimates and assumptions that affect the amounts
    recorded in the financial statements and accompanying notes. Actual
    results may differ from these estimates.

    Certain prior year amounts have been reclassified to conform to the
    current year's presentation.

3.  Plan Termination

    Although the Companies have not expressed any intent to do so, the
    Companies reserve the right to discontinue or terminate the Plan at any
    time. If the Plan should be terminated, in whole or in part, Participants
    will be entitled to withdraw the full value of their accounts, to the
    extent allowed by law.

4.  Descriptions of Funds

    The following are brief descriptions of the Funds currently available to
    Participants at December 30, 2001:

    Fund A - Company Common Stock Fund
    This Fund consists entirely of shares of FirstEnergy Corp. common stock.
    The Fund provides an opportunity for employees to increase their common
    ownership stake in FirstEnergy. The objective for this Fund is the growth
    of capital through both appreciation and dividend income. The Fund also
    holds the Companies' pre-ESOP matching contribution in FirstEnergy common
    stock. The common stock is purchased by the Trustee on the open market.
    The market value of the common stock is measured by the quoted market
    price.

Notes to Financial Statements
December 30, 2001 and 2000
--------------------------------------------------------------------------------

    Fund B - Capital Preservation Fund
    This Fund consists of guaranteed fixed income contracts issued by
    insurance companies and banks, collateralized mortgage obligations, and
    short-term money market instruments. These contracts guarantee interest
    for a fixed period and the principal amount of all investments. The
    average yield of the contracts was 5.97 % and 6.21% for the years 2001
    and 2000, respectively. The crediting interest rate as of December 30,
    2001 and 2000 was 5.51% and 6.25%, respectively. The market value of the
    Capital Preservation Fund is measured at the contract value as determined
    by the insurers and banks and no valuation reserve in relation to the
    contract value is deemed necessary.

    Fund C - S&P 500 Index Fund
    This Fund is a common/collective trust investing in the S&P 500 stocks.
    The objective of this Fund is the growth of capital through both
    appreciation and dividend income. The market value of the S&P 500 Index
    Fund is based on the market value per share determined by the Trustee.

    Fund D - Small Cap Value Fund
    This Fund invests primarily in securities of well-financed small cap
    companies at a substantial discount to what the manager believes are
    takeover values. The manager is EQSF Advisors, Inc. and the mutual fund
    name is Third Avenue Value. The objective of the Fund is to match or
    exceed the returns of the Russell 2000 Value Index over time.

    Fund E - Large Cap Value Fund
    The Fund seeks long-term capital appreciation and income by focusing on
    domestic large company equities that are selling at modest prices to
    earnings multiples. Shares are usually held for the long-term. Only
    extreme valuations or major changes to a company's fundamentals will
    trigger a sale. The portfolio manager is Davis Selected Advisors, L.P.
    and the mutual fund name is Selected American Fund. The performance
    objective is to match or exceed the S&P/Barra Large Cap Value Index over
    time.

    Fund F - Mid Cap Value Fund
    The Fund seeks long-term capital appreciation by investing in mid-sized
    companies that are less closely monitored by the investment community as
    evidenced by low institutional ownership and analyst coverage. The goal
    is to find well-managed companies that have sustainable growth prospects
    but that are selling at prices below their private market value. The
    manager believes that these factors may cause shares to be undervalued.
    The manager may sell a stock when its price no longer compares favorably
    with the company's private market value. The portfolio manager is Strong
    Capital Management and the mutual fund name is Strong Opportunity Fund.

    Fund G - Mid Cap Growth Fund
    The Fund seeks long-term capital appreciation by investing in mid cap
    companies that are leaders in attractive growth markets and in securities
    of higher risk accelerating growth companies. These securities are driven
    by product cycles, favorable sector conditions or other company specific
    factors expected to produce rapid sales and earnings growth. The Fund's
    investments are usually bought and sold relatively frequently. The
    portfolio manager is Invesco Funds Group, Inc. and the mutual fund name
    is Invesco Dynamics Fund.

7.  Contributions

    Employer Contributions
    The Companies pay a matching contribution of 50% on the first 6% of
    compensation contributed by an employee. In addition, the Companies may
    designate a number of performance objectives and contribute for each
    objective achieved, an additional $.05, up to a maximum of $.25, on each
    $1.00 of the first 6% of compensation contributed by an employee. The
    Companies' contributions are always invested in FirstEnergy common stock.

    The Companies' contributions have been pre-funded by the FirstEnergy
    common stock held by the ESOP Unallocated Fund. These shares of
    FirstEnergy common stock earn dividend income and are subject to
    unrealized appreciation and depreciation as the market value of the
    FirstEnergy common stock fluctuates. The dividend income serves to pay
    the ESOP Loan and related interest, which results in the release of
    shares to the ESOP Allocated Fund as the Companies' matching
    contribution. To the extent dividend income is not sufficient to pay the
    ESOP Loan and interest, the Companies will contribute cash which is
    reflected as employer contributions in the Statements of Changes in Net
    Assets Available for Plan Benefits.

December 30, 2001 and 2000
--------------------------------------------------------------------------------

    Employee Contributions
    During 2001 and 2000, employees could invest between 1% and 16% of their
    salary in the Plan. Employee contributions may be made on a before-tax
    and/or after-tax basis. Under the before-tax option, deposits are
    deducted from current taxable income but are taxable when they are
    withdrawn from the Plan. The Tax Reform Act of 1986 limited the maximum
    annual before-tax contribution to $10,500 for 2001 and 2000. Prior to age
    59-1/2, an active employee may withdraw before-tax deposits only under
    certain hardship conditions as defined in the Plan document.

    Employees may make rollover contributions to the Plan of funds held in
    other tax-qualified plans which the employee was a participant of prior
    to becoming employed by the Companies. The rollover contributions must be
    the result of a qualified total distribution from another tax-qualified
    plan and must be contributed to the Plan within 60 days after
    distribution to the employee.

    Both employer and employee contributions under the Plan are held in a
    trust fund with an independent trustee (State Street Bank & Trust
    Company). Employees may choose to invest their contributions in Funds A,
    B, C, D, E, F, G, H, I, J, K or M (see Note 4) which are offered by the
    Plan. Employees may also elect to borrow from their before-tax accounts
    for certain approved purposes (Fund L).

    During 2000, non-union participants from the former Beaver Valley Power
    Station 401(k) Plan were merged into the Plan (see Note 9). The
    transferred assets include Duquesne Light Company common stock (Fund N).

8.  Tax Considerations

    The Plan was amended and restated as the FirstEnergy Corp. Savings Plan
    effective July 1, 1998. The Companies have not yet applied for a
    determination letter from the Internal Revenue Service.

    Management believes the Plan is exempt from federal, state and local
    income taxes. The federal, state and local income tax treatments of
    distributions from the Plan depend upon when they are made and their
    form. The withdrawal of the principal amount of a Participant's after-tax
    contribution is not, however, subject to tax. For tax years beginning
    after December 31, 1986, the Tax Reform Act of 1986 requires that an
    additional tax of 10% be applied to employee withdrawals from the Plan
    prior to death, disability, attainment of age 59-1/2, or under certain
    other limited circumstances.

    In the case of withdrawal by a Participant employed by the Companies
    prior to the attainment of age 59-1/2, the excess of the value of the
    withdrawal over the total amount of the Participant's after-tax
    contributions, is taxable at ordinary income tax rates. The value of the
    Companies common stock withdrawn is considered to be its fair value on
    the date it is withdrawn.

    In the case of a distribution that qualifies as a lump-sum distribution
    upon a Participant's termination of employment with the Companies or
    after attaining the age of 59-1/2, only the excess of the value of the
    lump sum distribution over the amount of the Participant's after-tax
    contributions to the Plan (less withdrawals) is taxable at ordinary
    income tax rates. In determining the value of the lump-sum distribution,
    the FirstEnergy common stock distributed in-kind or in cash shall be
    valued at fair value on the date it is withdrawn.
