THE COMPANY

The Company was incorporated under the laws of the State of New York in 1906 and reorganized in 1925. Its principal executive office is located at 1 Riverside Plaza, Columbus, Ohio 43215 and its telephone number at that address is (614) 716-1000.

The Company is a public utility holding company which owns, directly or indirectly, all of the outstanding common stock of its operating electric utility subsidiaries. Substantially all of the Company's operating revenues are derived from the furnishing of electric service. The Company is also referred to as “AEP” in this Prospectus.


ADVANTAGES OF THE PLAN

 If you do not currently own any shares of our Common Stock, you may enroll in the Plan by making initial cash investment of at least $250, or by authorizing a minimum of 10 automatic withdrawals of at least $25 plus, in either case, an initial investment fee of $10.00.

 You may reinvest all or a portion of your cash dividends in our Common Stock.

 You may receive cash dividends electronically or by check on all or any shares of our Common Stock, including those held in the Plan.

 You may purchase additional shares of our Common Stock as often as weekly by making voluntary cash payments up to a maximum of $150,000 per calendar year. Voluntary investments may be made by check or automated deduction from a predesignated checking, savings or money market account.

 Employees may make initial purchases of our Common Stock without an initial invest-ment fee. The minimum purchase for employees is $5.00.

 You pay no brokerage fees or expenses in connection with purchases of our Common Stock under the Plan.

 You may establish an IRA which invests in our Common Stock through the Plan.

 Full investment of funds is possible under the Plan because the Plan permits fractions of shares, as well as full shares, to be credited to your account.

 The Plan offers a share "safekeeping" service whereby you may deposit your Common Stock certificates with the Agent and have your ownership of our Common Stock maintained on the Agent's records as part of your Plan account.

 You may make transfers or gifts of our Common Stock at any time and at no charge to you. When you transfer or give shares to another person, an account will be opened for the recipient and the recipient will enjoy full plan benefits.

 Quarterly statements are mailed to you if you reinvest dividends listing year-to-date transactions in your account. Transaction advices are mailed after voluntary cash payments unless included in a quarterly statement. Annual statements are mailed to all Plan Participants who had activity in the account during that year.


COMPANY RISK FACTORS

Investing in our securities involves risk. Please see the risk factors descried in our Annual Report on Form 10-K, as amended by Form 10-K/A, for the fiscal year ended December 31, 2004, along with disclosure related to the risk factors contained in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2005, which are incorporated by reference in this prospectus. Before making an investment decision, you should carefully consider these risks as well as other information contained or incorporated by reference in this prospectus. The risks and uncertainties described are those presently known to us. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also impair our business operations, our financial results and the value of our securities. There may be risks that you view in a different way than we do, and we may omit a risk that we consider immaterial, but you consider important. If any of the following risks occur, our business, financial condition or results of operations could be materially harmed. In that case, the value or trading price of the securities registered herein could decline, and you may lose all or part of your investment.


FORWARD-LOOKING STATEMENTS

We have included, in the documents incorporated by reference in this Prospectus, statements containing “forward-looking information,” as defined by the Private Securities Litigation Reform Act of 1995. We have used the words “anticipate,”“intend,”“may,”“expect,”“believe,”“plan,”“will,”“estimate,”“should” or other comparable and similar expressions in this Prospectus and in the documents incorporated by reference to identify such forward-looking statements. Forward-looking information, by its nature, involves estimates, projections, goals, forecasts, assumptions, risks and uncertainties that could cause actual results or outcomes to differ materially from those expressed in a statement that contains forward-looking information. Any statement containing forward-looking information speaks only as of the date on which it is made, and, except to fulfill our obligations under the U.S. securities laws, we undertake no obligation to update any such statement to reflect events or circumstances after the date on which it is made. Examples of factors that can affect our expectations, beliefs, plans, goals, objectives and future financial or other performance are discussed under the heading “Company Risk Factors.” All such factors are difficult to predict, contain uncertainties that may materially affect actual results, and may be beyond our control. It is not possible for our management to predict all of such factors or to assess the effect of each such factor on our business. New factors emerge from time to time, and may be found in the future SEC filings incorporated by reference in this Prospectus in the section captioned “Where You can Find More Information.”


DESCRIPTION OF THE PLAN

The following is the Plan for our investors, shareholders and employees, which became effective July 1, 1997.

Purpose

The purpose of the Plan is to provide you with a convenient and economical way to purchase shares of our Common Stock and to reinvest all or a portion of your cash dividends in additional shares of our Common Stock. To the extent such shares of our Common Stock are purchased from us, we will receive additional funds needed for the repayment of debt, for additional equity investments in our subsidiaries and for other corporate purposes.

Administration

EquiServe Trust Company, N.A. (“EquiServe”), a federally chartered trust institution, as Agent, administers the Plan for you, keeps records, sends statements of account to you and performs other duties relating to the Plan. Computershare Shareholder Services, Inc., an affiliate of EquiServe and a transfer agent registered with the SEC, acts as service agent for EquiServe. The Agent purchases shares of our Common Stock, either on the open market or directly from us, as agent for you and credits the shares to your individual accounts.

Eligibility

Any person or legal entity, residing in the United States, whether or not a shareholder of record of our Common Stock, is eligible to participate in the Plan. Citizens or residents of a country other than the United States, its territories and possessions, are eligible to participate if such participation would not violate laws applicable to the Company or the Participant.

Beneficial owners of our Common Stock are owners whose shares are registered in names other than their own (for instance, in the name of a broker or bank nominee). In order to participate in the Plan, such beneficial owners must become shareholders of record by having shares transferred into their own names. Beneficial owners may direct their broker/dealers to have some or all of their shares reregistered into their names. The broker/dealer should be instructed to move some or all of the shares electronically through the Direct Registration System from the broker/dealer account to a new book-entry account with the Agent. Please contact the broker/dealer for more information. Once the shares are moved from the broker/dealer account to a new book-entry account registered in the owner’s name with the Agent, the individual may then participate in the Plan.

Enrollment Procedures

Shareholders of Record

If you are a shareholder of record you may become a Participant in the Plan by enrolling through the Internet by going to the Plan Agent’s website, www.computershare.com/equiserve, and following the instructions provided, or by sending a completed Enrollment Authorization Form to the Agent. The initial investment fee does not apply to shareholders of record.

Investors

After reading a copy of this Prospectus, investors may apply for enrollment in the Plan by completing all required sections of the Initial Investment Form and sending it to the Agent. The Initial Investment Form must be accompanied by either an Authorization Form for Automatic Deduc-tions of at least $25 per month for a minimum of 10 months, or an initial cash payment in the form of a check made payable (in U.S. dollars) to Computershare. Investors may also apply for enrollment in the Plan through the Agent’s website, www.computershare.com/equiserve and following the instructions provided. The minimum amount for an initial cash investment is $250 and the amount cannot exceed $150,000 in a calendar year. A $10 initial investment fee will be deducted from the initial invest-ment payment. Do not send cash, money orders, traveler’s checks or third party checks. No interest will be paid on investment amounts held by the Agent pending the purchase of shares.

If the Plan account will be in more than one name, all potential Participants must sign the Initial Investment Form. The Agent reserves the right to limit or combine Plan accounts with identical tax-payer identification numbers and legal registrations.

Employees

Most full or part-time employees or any of our subsidiaries may apply for enrollment in the Plan by returning a completed Employee Enrollment Form which is available from the Shareholder Relations office at 1 Riverside Plaza, Columbus, Ohio 43215. No enrollment fees will be charged to employees. See also "Employee Participation."

Enrollment Authorization Form

Three options are shown on the Enrollment Authorization Form. You must place an "X" in the appropriate box to indicate your investment intent. Options are (1) full reinvestment of dividends, (2) partial reinvestment of dividends (whereby the number of shares to receive cash dividends is indicated, and the dividends on all remaining shares are reinvested), and (3) voluntary cash payments only (no dividend reinvestment). Under each of these options, you may make voluntary cash payments at any time. You may change reinvest-ment levels from time to time by accessing your Plan account at the Agent’s website, www.computershare.com/equiserve or by submitting a revised Enrollment Authorization Form to the Agent.

Reinvestment of Dividends

You may elect full reinvestment, partial reinvestment and partial cash, or full cash payment of all dividends by completing the Enrollment Authorization Form as described above. If you choose partial reinvestment, you need to designate on the Enrollment Authorization Form the number of whole shares to receive cash dividends. Dividends paid on all of the Participant's other shares in the Plan will be reinvested.

Once you elect full reinvestment, cash dividends paid on all our Common Stock registered in your name and/or held in your Plan account will be reinvested in additional shares of our Common Stock on the dividend payment date (Dividend Payment Investment Date). If the Participant has specified partial reinvestment, that portion of such dividend payment not reinvested will be sent to you by check in the usual manner or directly deposited, if you have elected the direct deposit option (see "Direct Deposit of Dividends Not Reinvested" below).

Direct Deposit of Dividends Not Reinvested. Through the Plan's direct deposit feature, you may elect to have any cash dividends not reinvested under the Plan paid by electronic funds transfer to your predesignated bank account. To receive such dividends by direct deposit, you must first complete and sign the Direct Deposit Authorization Form and return the form to the Agent. This form is not part of the Enrollment Authorization Form and must be specifically requested from the Agent.

Forms will be processed and will become effective promptly. You may change the designated account for direct deposit or discontinue this feature by written instruction to the Agent. If you transfer shares or otherwise establish a new account, a new Direct Deposit Authorization Form must be completed. If you close or change a bank account number, a new Direct Deposit Authorization Form must be completed.

Initial Investments and Voluntary Cash Payments

You may make investments by personal check, one-time online bank debit, or automatic deduction from a predesignated account. Voluntary cash payments must be a minimum of $25 and may not exceed $150,000 per calendar year. There is no obligation to make a voluntary cash payment at any time, and the amount of such payments may vary.

Investment Dates for Initial Investments and Voluntary Cash Payments

Initial investments and voluntary cash payments received by the Agent will be invested as soon as practicable; but in any event, such investments will be invested not later than five business days after they are received by the Agent (Voluntary Cash Investment Date). In order to be entitled to the next dividend to be paid, such investments must be received by the Voluntary Cash Investment Date which is prior to the ex-dividend date. The ex-dividend date is currently three business days prior to, and including, the record date, which record date historically has been on or about the 10th of February, May, August and November.

No interest will be paid on amounts held by the Agent pending investment. 

Upon your written or telephone request received by the Agent no later than two business days prior to the Voluntary Cash Investment Date, a cash payment not already invested under the Plan will be cancelled or returned to you, as appropriate. However, no refund of a check will be made until the funds have been actually received and collected by the Agent. Accordingly, such refunds may be delayed.

Methods of Payments

Check. Voluntary cash payments may be made by check pay-able in U.S. dollars to "Computershare." Voluntary cash payments must be sent to the Agent together with the Transaction Form attached to each quarterly account statement or the transaction advice sent to Participants or with a letter indicating the account number. You should also indicate the Plan account number on your check. Do not send cash, traveler’s checks, money orders, or third party checks for voluntary cash payments. Additional Transaction Forms are available upon request from the Agent.

For initial cash investments, see "Enrollment Procedures — Investors" above.

One-time Bank Debit. At any time, Participants may make voluntary cash payments by going to the Agent’s website, www.computershare.com/equiserve, and authorizing a one-time online bank debit from an account at U.S. bank or financial institution. One-time online voluntary cash payment funds will be held by the Plan Agent for three banking business days before they are invested. You should refer to the online confirmation for the account debit date and investment date.

Automatic Deduction from an Account. You may make automatic investments of a specified amount (up to $150,000 per calendar year) through an Automated Clearing House (ACH) withdrawal from a predesignated account at a U.S. bank or financial institution. To initiate automatic deductions, you may enroll through the Agent’s website, www.computershare.com/equiserve, or, complete and sign an Authorization Form for Automatic Deductions and return it to the Agent together with a voided blank check or savings account deposit slip for the account from which funds are to be drawn. Forms will be processed and will become effective as promptly as practicable; however, you should allow four to six weeks for your first investment to be initiated. Once automatic deductions are initiated, funds will be drawn from your account on either the 1st or 15th of each month, or both (as chosen by you, or the next business day if either the 1st or the 15th is not a business day, and will normally be invested within five business days). Automatic deductions will continue at the level you set until you change your instructions by notifying the Plan Agent.

You may change or terminate automatic deductions through the Agent’s website, www.computershare.com/equiserve or by completing and submitting to the Agent a new Authorization Form for Automatic Deductions. When you transfer shares or otherwise establish a new account, an Authorization Form must be completed unique to that account. If you close or change a bank account number, a new Authorization Form must be completed. To be effective with respect to a particular Voluntary Cash Investment Date, however, the new Authorization Form for Automatic Deductions must be received by the Agent at least six business days preceding the date the funds will be withdrawn.

There is a fee of $25 for any voluntary cash payment returned unpaid, whether the investment was made by check or by an attempted automatic withdrawal from your U.S. bank account. By enrolling in the Plan, you authorize the Agent to deduct this fee by selling shares from your Plan account. More Common Stock may be sold than was purchased with the returned deposit due to fluctuations in market price.

Source and Price of Shares

If shares are purchased for the Plan on the open market, the Agent may, at its sole discretion, begin purchasing shares no earlier than three business days prior to any Investment Date and complete purchasing shares no later than 30 days after such date except where beginning at an earlier date is permissible, or where completion at a later date is necessary or advisable, under applicable federal regulatory and securities laws. The Agent will use its best efforts to cause all funds received by it to be applied to the purchase of shares within the above dis-cussed time period. If such shares are purchased directly from us, such purchase shall take place on the Investment Date.

For an open market purchase, the purchase price for our Common Stock will be the average price, excluding brokers' commissions, paid by the Agent for all such shares purchased on the open market with respect to the Investment Date.

The price of shares of our Common Stock purchased directly from us will be the average of the daily high and low sales prices of our Common Stock (as published in The Wall Street Journal report of New York Stock Exchange — Composite Transactions) for the period of five trading days ending on the Investment Date.

If both open market purchases and purchases directly from us are made with respect to any Investment Date, the price of the shares purchased will be the weighted average of both such prices.

The amount of the investment divided by the price per share will determine the number of shares credited to your account.

Cost to Participants

An initial investment fee of $10 will be charged to all non-shareholders (except our employees) who elect to participate in the Plan. Brokerage commissions and other expenses for shares purchased on the open market will be paid by us. These commissions will be considered as additional income to you for tax purposes and will be reported on year-end tax statements. There are no brokerage fees for shares purchased directly from us. You pay a service fee and brokerage commissions ($5.00 and approximately 12 cents a share) on shares that are sold through the Plan at your request.


INDIVIDUAL RETIREMENT ACCOUNT

The Agent offers an Individual Retirement Account (Traditional, Roth or Coverdell Education Savings Account) that invests in our Common Stock through the Plan. This account is available for new contributions and for roll-overs. For more information on this service, including IRA enrollment material and fees, go to www.computershare.com/equiserve or call the Agent’s IRA Department at 1-800-597-7736.
 


ACCOUNT MANAGEMENT

Once a Plan account is established, you have several other options available to manage the account, including transfers, sales and certificate issuance. These options are detailed below.


Gift/Transfer of Shares

If you wish to transfer the ownership of all or part of your shares held under the Plan to a Plan account for another person, whether by gift, private sale or otherwise, you may effect such transfer by mailing a properly completed Gift/Transfer Form, or an executed stock power, to the Agent. There is no initial investment fee charged to the recipient. Transfers of less than all of your shares must be made in whole share amounts. Requests for transfer are subject to the same requirements as the transfer of our Common Stock certificates, including the requirement of a medallion signature guarantee on the stock power or Gift/Transfer Form. Gift/Transfer Forms and Stock Power Forms are avail-able on the Agent’s website, www.computershare.com/equiserve and upon request from the Agent.

Shares so transferred will continue to be held by the Agent under the Plan. An account will be opened in the name of the recipient, if he or she is not already a Participant, and such recipient will automatically be enrolled in the Plan. If the recipient is not already a registered shareholder or a Participant, the account will be enrolled under the full reinvestment option unless the donor specifies differently. The recipient may change the reinvestment election after the gift has been made as described under "Reinvestment of Dividends" above.

If a transfer involving all shares in your account is received after a record date but before the related dividend payment date, the transfer will be processed when received, and a cash dividend will be paid to you.

The recipient will receive a statement showing the deposit of shares. Upon your request, the Agent will also send a non-negotiable gift certificate free of charge.

Sale of Shares

You may request the Agent to sell any number of whole shares held in your Plan account by accessing your account through the Internet at the Agent’s website, www.computershare.com/equiserve, by completing the transaction form attached to your statement or by giving detailed written instructions to the Agent. Alternatively, you may call the Agent at 1-800-328-6955. The Agent will initiate the sale as soon as practicable after receiving the notification. Sales will be made for your account on the open market through a securities broker designated by the Agent. You will receive the proceeds, less applicable service fee and brokerage commis-sions ($5.00 and approximately 12 cents per share). Proceeds of shares sold through the Plan will be paid to you by check.

You may also customize your payment preference for many different currencies through the Agent’s Global Payments services. Just provide the Agent with your payment preference via the Internet and let them know where you want your money deposited. No matter where you’re located you can take advantage of the flexibility. To register for Global Payments, go to www.computershare.com/equiserve, click on “Account Access” and follow the log-in instructions.

If instructions for the sale of all shares are received on or after an ex-dividend date, as set by the NYSE, but before the related dividend payment date, the sale will be processed as described above and a separate check for the dividend will be mailed following the dividend payment date. A request to sell all shares held in your account will be treated as a withdrawal from the Plan. See "Closing a Plan Account" below.

All sales requests having an anticipated market value of $100,000 or more must be submitted in written form. In addition, all sale receipts received by the Agent within 30 days of an address change to your Plan account must be submitted in written form.

Certificates for Shares

Shares purchased and held under the Plan will be held in safekeeping by the Agent in your name. The number of shares (including fractional shares) upon which dividends are reinvested and held for each Participant will be shown on each quarterly statement of account. You may obtain a new certificate for all or some of the whole shares of our Common Stock held in your Plan account by completing the transaction form attached to your statement or upon telephone or written request to the Agent. You may also request a certificate through the Agent’s website, www.computershare.com/equiserve. Any remaining whole or fractional shares will continue to be held by the Agent. Withdrawal of shares in the form of a certificate in no way affects dividend reinvestment on those shares (see "Reinvestment of Dividends" above). When issued, certificates for shares will be registered in the name in which the Plan account is maintained.

Except as described in "Gift/Transfer of Shares" above, shares of our Common Stock held by the Agent for your Plan account may not be pledged or assigned. If you wish to pledge or assign any such shares, you must request that a certificate for such shares be issued in your name.

Share Safekeeping

At the time of enrollment in the Plan, or at any later time, you may use the Plan's share safekeeping service to deposit any Common Stock certificates in your possession with the Agent. Shares deposited will be credited to your account under the Plan. Thereafter, such shares will be treated in the same manner as shares purchased through the Plan. If a certificate issuance is later requested, a new, differently numbered certificate will be issued.

By using the Plan's share safekeeping service, you no longer bear the risk associated with loss, theft or destruction of our Common Stock certificates. Also, because shares deposited with the Agent are treated in the same manner as shares purchased through the Plan, they may be transferred or sold through the Plan in a convenient and efficient manner (see "Closing a Plan Account" below and "Sale of Shares" and "Gift/Transfer of Shares" above). There is no charge for this custodial service.

If you wish to deposit your Common Stock certificates with the Agent, you must mail your request and your certificates to the Agent. The certificates should not be endorsed.

Certificates mailed to the Agent should be insured for possible mail loss for 3% of the market value (minimum of $20.00); this represents your replacement cost if the certificates are lost in transit to the Agent.

Closing a Plan Account

You may close an account in the Plan at any time by accessing your account through the Internet at the Agent’s website, www.computershare.com/equiserve, completing the information on the transaction form attached to the Plan statement or transaction advice or by giving telephone or written instructions to the Agent. Upon withdrawal from the Plan, a certificate for the whole shares held in the Plan for you will be issued. If you close a Plan account, you will receive a check for the cash value of any fractional share. Alternatively, you may specify in the withdrawal notice that all or a portion of whole shares be sold. The Agent will make the sale as soon as practicable after receipt of the withdrawal notice, and you will receive a check for the proceeds, less a service fee and any applicable brokerage commissions. If notice of withdrawal is received on or after an ex-dividend date but before the related dividend payment date, the withdrawal will be processed as described above and a separate check for the dividend will be mailed following the dividend payment date.

No voluntary cash payments may be made after participation in the Plan has been terminated. In order to initiate participation, you must re-enroll.

If you dispose of all certificated shares of our Common Stock, the dividends on the shares credited to the your Plan account will continue to be distributed as elected on the Enrollment Authorization Form until the Agent is notified that you wish to withdraw from the Plan.

Reports to Participants

You will receive a quarterly statement showing the amount invested, purchase price, the number of shares purchased, deposited, sold, transferred or withdrawn, total shares accumulated and other year-to-date information. The quarterly statement will indicate the shares held by the Agent for you and other shares registered in your name upon which dividends are reinvested. You are responsible for retaining these statements in order to establish the cost basis of shares purchased under the Plan for tax purposes. Duplicate statements for open accounts will be available from the Agent. However, charges may be assessed for statements for closed accounts. You may also view year-to-date transaction activity in your Plan account for the current year, as well as activity in prior years, by accessing your Plan account through the Internet at the Agent’s website, www.computershare.com/equiserve.

You will be sent the same communications sent to all other registered holders of shares of our Common Stock, including the Company's annual report to shareholders, a notice of the annual meeting and accompanying proxy statement. In addition, you will receive an Internal Revenue Service information return for reporting dividend income received and/or shares sold, if so required.

All notices, statements and reports from the Agent to a Participant will be addressed to you at the latest address of record with the Agent. Therefore, you must promptly notify the Agent of any change of address. Failure to do so may result in escheatment of the account to the state of your last known address, in accordance with applicable state laws.


FEDERAL INCOME TAX INFORMATION

We believe the following is an accurate summary of the tax consequences of participation in the Plan as of the date of this Prospectus. This summary may not reflect every possible situation that could result from participation in the Plan, and, therefore, you are advised to consult your tax advisor with respect to the tax consequences (including federal, state, local and other tax laws and U.S. tax withholding laws) applicable to your particular situation.

Taxable Income and Tax Basis

Reinvested Dividends. In the case of reinvested dividends, when the Agent acquires shares for your account directly from us, you must include in gross income a dividend equal to the number of shares purchased with your reinvested dividends multiplied by the fair market value of our Common Stock on the relevant dividend payment date. The fair market value is based on 100% of the average of the high and low market prices on the dividend payment date. Your tax basis in those shares will also equal the fair market value of the shares on the relevant dividend payment date.

Alternatively, when the Agent purchases our Common Stock for your account on the open market with reinvested dividends, you must include in gross income an amount equal to the cash dividends reinvested plus that portion of any brokerage commissions paid by us which are attributable to the purchase of your shares. Your tax basis in Plan shares will be equal to the purchase price plus allocable brokerage commissions.

Voluntary Cash Payments. In the case of shares purchased on the open market with volun-tary cash payments, shareholders will be in receipt of a dividend to be included in gross income to the extent of any brokerage commissions paid by us. Your tax basis in the shares acquired with voluntary cash payments will be the cost of the shares to the Agent plus an allocable share of any brokerage commissions paid by us.

The above rules are based on an Internal Revenue Service (IRS) ruling we obtained with respect to the Plan. These rules may not be applicable to certain Participants in the Plan, such as tax-exempt entities (e.g., IRA accounts and pension funds) and foreign shareholders. You should consult your tax advisor concerning the tax con-se-quences applicable to your situation.

Gain/Loss Recognition. You will not realize any taxable income when a certificate is received for whole shares credited to the account, either upon request for such certificates or upon withdrawal from or termination of the Plan. However, a gain or loss will be recognized by you when whole shares acquired under the Plan are sold or exchanged — either by the Agent at your request when withdrawing from the Plan or by your own action after withdrawal from or termination of the Plan. You also will recognize gain or loss when receiving a cash payment for a fractional share credited to your account is sold upon withdrawal from or termination of the Plan. The amount of the gain or loss will be the difference between the amount of cash received for the shares or fractional shares and the tax basis of those shares.

Information Returns

You will receive a Form 1099-DIV at the end of each year, or shortly thereafter, which provides the amount of dividend income that is reportable to the IRS, including, where applicable, an amount for brokerage commissions paid on your behalf, and an adjust-ment to reflect the difference between fair market value price and purchase price with respect to shares purchased from us with reinvested dividends.

A Form 1099-B will be provided if you sold shares through the Plan.

A copy of each information return is also furnished to the IRS.

Withholding Provisions

Federal law requires the Agent to withhold an amount at the current applicable rates from the amount of dividends and the proceeds of any sale of shares if: (i) you fail to certify to the Agent that you are not subject to backup withholding, (ii) that you fail to certify that the taxpayer identification number provided is correct or (iii) the IRS notifies us that you are subject to backup withholding. The withheld amounts will be deducted from the amount of dividends and the remaining amount will be reinvested. The with-held amounts also will be deducted from the proceeds of any sale of shares and the remaining amount will be sent to you.

In the case of those foreign shareholders whose dividends are subject to United States income tax withholding, the amount of tax to be withheld will be deducted from the amount of dividends and the remaining amount of dividends will be reinvested. In the case of those foreign share-holders whose sale proceeds are subject to withholding, the amount of tax to be withheld will be deducted from the proceeds of the sale of shares.


EMPLOYEE PARTICIPATION

Rights of Employees Under the Plan. Our employees have the same rights under the Plan, and are governed by the same terms and limitations, as our shareholders, except that employees (i) may enroll in the Plan to purchase shares with voluntary cash payments without paying an enrollment fee and (ii) may arrange with their employers to make such voluntary cash payments through regular payroll deductions. Voluntary cash payments by employees, including payroll deductions, have a minimum investment of $5.00 and may not exceed $150,000 per calendar year.

Enrollment. An employee may enroll in the Plan at any time to purchase shares of our Common Stock with voluntary cash payments by completing an Employee Enrollment Form and returning it to the Shareholder Relations Department. Employee Enrollment Forms and with-holding authorization forms may be obtained from the Human Resources Department or administrator of the employee's company or by request to the Shareholder Relations Depart-ment, American Electric Power Service Corporation, 1 Riverside Plaza, Columbus, Ohio 43215. If an employee elects to make voluntary cash payments directly to the Agent and does not authorize payroll deductions, the Enrollment Form must be accompanied by a check for the initial payment.

Employees who, as record holders of our Common Stock, are already participating in the Plan do not need to complete an Employee Enrollment Form; however, they must complete a with-holding authorization form if they wish to make voluntary cash payments through payroll deductions. Any employee who is or becomes a holder of record of our Common Stock may obtain from the Agent and execute a shareholder Enrollment Authorization Form in order to provide for the reinvestment of cash dividends on those shares.

Payroll Deductions. An employee may authorize the deduction of a specified whole dollar amount from each month's pay. The minimum monthly deduction is $5. Once authorized, payroll deductions will continue until changed or terminated by the employee.

An employee may change the amount of a payroll deduction or terminate payroll deductions by giving written notice to the employer's Human Resources Department or administrator. Employees should allow at least 15 days' processing time prior to the end of the pay period in which the deduction is made for any change or termination to become effective. Employees may terminate payroll deductions without withdrawing from the Plan and continue to invest by making voluntary cash payments directly to the Agent.

Withdrawal From the Plan. In order to withdraw from the Plan, Employee-Participants must notify the Agent by telephone or in writing of their intent to withdraw, and employees making voluntary cash payments through payroll deductions must also notify their employer of such intent to withdraw.

If an Employee-Participant ceases to be employed by an American Electric Power System company, the Agent will continue dividend distribution as elected for the account on the shares credited to the Participant's Plan account until the Participant withdraws from the Plan. Participation in the Plan may continue as long as there are shares credited to the Participant's Plan account or registered in the Participant's name.


DESCRIPTION OF COMMON STOCK

The Company’s capital stock currently consists of 600,000,000 shares of common stock, par value $6.50 per share. 395,704,805 shares of our common stock were issued and outstanding as of October 31, 2004. Our Common Stock is listed on the New York Stock Exchange. EquiServe is the transfer agent and registrar for our Common Stock.

Dividend Rights. The holders of our Common Stock are entitled to receive the dividends declared by our board of directors provided funds are legally available for such dividends. Our income derives from our Common Stock equity in the earnings of our subsidiaries. Various financing arrangements, charter provisions and regulating requirements may impose certain restrictions on the ability of our subsidiaries to transfer funds to us in the form of cash dividends, loans or advances.

Stock Split, Stock Dividend or Rights Offering. Any stock dividends or split shares of our Common Stock distributed by us on shares held by the Agent for your Plan account or held by you in the form of stock certificates will be added to your account.

In the events of a rights offering, you will receive rights based upon the total number of whole shares owned, that is, the total number of shares registered in your name and the total number of whole shares held in your Plan account.

Rights upon Liquidation. If we are liquidated, holders of our Common Stock will be entitled to receive pro rata all assets available for distribution to our shareholders after payment of our liabilities, including liquidation expenses.

Preemptive Rights. The holders of our Common Stock generally do not have the right to subscribe for or purchase any part of any new or additional issue of our Common Stock. If, however, our board of directors determines to issue and sell any Common Stock solely for money and not by (1) a public offering, (2) an offering to or through underwriters or dealers who have agreed to promptly make a public offering, or (3) any other offering which the holders of a majority of our outstanding Common Stock have authorized; then such Common Stock must first be offered pro rata to our existing shareholders on terms no less favorable than those offered to persons other than our existing shareholders.

Voting of Plan Shares. The holders of our Common Stock are entitled to one vote for each share of common stock held. The holders of our Common Stock are entitled to cumulate their votes when voting for the election of directors. For each meeting of shareholders, you will receive a proxy for the total number of whole shares held — both the shares registered in your name directly and those credited to your Plan account. Fractions of shares will not be voted. If the proxy is not returned, or if it is returned unsigned, none of the shares will be voted unless you vote in person.

Restrictions on Dealing with Existing Shareholders. We are subject to Section 513 of New York’s Business Corporation Law, which provides that no domestic corporation may purchase or agree to purchase more than 10% of its stock from a shareholder who has held the shares for less than two years at any price that is higher than the market price unless the transaction is approved by both the corporation’s board of directors and a majority of the votes of all outstanding shares entitled to vote thereon at a meeting of shareholders, unless the certificate of incorporation requires a greater percentage or the corporation offers to purchase shares from all the holders on the same terms. Our certificate of incorporation does not currently provide for a higher percentage.


OTHER INFORMATION

Limitation of Liability. Neither we nor the Agent (nor any of their respective agents, representatives, employees, officers, directors or subcontractors) will be liable in administering the Plan for any act done in good faith or for any good faith omission to act, including, without limitation, any claim of liability arising from failure to terminate your account upon your death, or with respect to the prices or times at which shares are purchased or sold for you. The foregoing does not represent a waiver of any rights you may have under applicable securities laws. Neither we nor the Agent can assure a profit or protect against a loss on shares purchased under the Plan. 

Change or Termination of Plan. We reserve the right to modify the Plan (consistent with any applicable shareholder resolutions and subject to any requisite authorization or approval by regulatory agencies having jurisdiction), or to suspend or terminate the Plan, at any time. You will be sent notice of any such action. Any such modification, suspension or termination will not, of course, affect previously executed transactions. We also reserve the right to adopt, and from time to time to change, such administrative rules and regulations (not inconsistent in substance with the basic provisions of the Plan then in effect) as it deems desirable or appropriate for the administration of the Plan. The Agent reserves the right to resign at any time upon reasonable written notice to us.


USE OF PROCEEDS

We have no basis for estimating precisely either the number of shares of our Common Stock that ultimately may be sold pursuant to the Plan, or the prices at which such shares will be sold. However, we propose to use the net proceeds from the sale of shares of our Common Stock by us pursuant to the Plan, when and as received, to pay at maturity unsecured debt outstanding at the time, to make, subject to the receipt of any necessary authorizations from regulatory agencies, additional investments in our Common Stock equities of our subsidiaries, and for other corporate purposes.


VALIDITY OF COMMON STOCK

Simpson Thacher & Bartlett LLP, New York, New York, our counsel, will pass upon the validity of the shares of our Common Stock offered hereby for us.


EXPERTS

The consolidated financial statements and the related consolidated financial statement schedule incorporated in this Prospectus by reference from the Company's Annual Report on Form 10-K for the year ended December 31, 2003 have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their reports (which reports express an unqualified opinion and include explanatory paragraphs concerning the adoption of new accounting pronouncements in 2002 and 2003), which are incorporated herein by reference and have been so incorporated in reliance upon the reports of such firm given upon their authority as experts in accounting and auditing.


INDEMNIFICATION FOR SECURITIES ACT LIABILITIES

Article 7, Sections 721-725 of the New York Business Corporation Law and the Company's By-Laws provide for indemnification of the Company's directors and officers in a variety of circumstances, which may include liabilities under the Securities Act of 1933 (the 1933 Act). In addition, the Company has purchased insurance, as permitted by Section 726 of the same New York statute, on behalf of directors, officers, employees or agents, which may cover liabilities under the 1933 Act.

Insofar as indemnification for liabilities arising under the 1933 Act may be permitted to directors, officers or persons controlling the Company pursuant to the foregoing provisions, the Company has been informed that in the opinion of the SEC such indemnification is against public policy as expressed in the 1933 Act and is therefore unenforceable.

Our Common Stock is listed on the New York Stock Exchange, Inc., where reports, information statements and other information concerning the Company may also be inspected.
