The Company is a regulated public utility that generates, purchases, transmits, distributes and sells electric energy in a 7,600 square mile area in Southeastern Michigan. The Company's service area includes about 13% of Michigan's total land area and about half of its population (approximately five million people). The Company's residential customers reside in urban and rural areas, including an extensive shoreline along the Great Lakes and connecting waters. Detroit Edison's executive offices are located at 2000 2nd Avenue, Detroit, Michigan 48226-1279. The telephone number is 313-235-8000. RISK FACTORS You should carefully consider the following risks, together with the other information included or incorporated by reference in this prospectus supplement and the attached prospectus, before buying any Bonds. UTILITY INDUSTRY AND ENVIRONMENTAL REGULATION MAY ADVERSELY AFFECT THE COMPANY'S OPERATING RESULTS Various bills have been introduced in the Michigan Legislature addressing competition in the electric markets. Detroit Edison is proceeding with the implementation of customer choice as provided in various orders of the Michigan Public Service Commission ("MPSC"). While Detroit Edison is unable to predict the impact, if any, of the outcome of these legislative proceedings, applicable MPSC orders provide for the recovery of stranded costs. The Company is subject to extensive environmental regulation. Additional costs may result as the effects of various chemicals on the environment (including nuclear waste) are studied and governmental regulations are developed and implemented. The costs of future nuclear decommissioning activities are the subject of increased regulatory attention. Ownership of Fermi 2, a nuclear generating unit, subjects the Company to additional significant risks. Nuclear plants are highly regulated by a number of governmental agencies concerned with public health and safety and environmental protection. Consequently, Fermi 2 is subject to greater scrutiny than a conventional fossil fueled plant.

Copies of the Mortgage and Deed of Trust and such supplements, hereinafter collectively referred to as the "Mortgage", are exhibits to the registration statement of which this prospectus supplement and the attached prospectus are a part, and reference is hereby made to the Mortgage for full and complete statements of the provisions thereof, including the definitions of certain terms used, and for other information with respect to the Bonds. The Mortgage and the general terms and provisions of the Mortgage Bonds are more fully described in the attached prospectus. The following statements concerning the Bonds supplement, and to the extent inconsistent therewith replace, the description of the Mortgage Bonds set forth in the attached prospectus. They do not purport to be complete and are qualified in their entirety by reference to the Mortgage. The Bonds will be senior secured obligations of the Company and will be limited to $40,000,000 aggregate principal amount. The Bonds will rank equally as to security with all Mortgage Bonds of all other series outstanding under the Mortgage, except insofar as any sinking, improvement or analogous fund may be deemed to afford additional security for the Mortgage Bonds of any series, and except that, as provided in Section 3 of Article VI of the Mortgage, the Trustee may, when in possession during a default, apply any residue of collections to payment of principal of such Mortgage Bonds as are then due if all of the Mortgage Bonds have not become due. See "Description of Debt Securities--Provisions Applicable to General and Refunding Mortgage Bonds" in the attached prospectus. The Bonds will be issued only in fully-registered form in denominations of $1,000 or any integral multiple thereof. The Bonds will be issued in book-entry form through the facilities of The Depository Trust Company ("DTC"). Transfers or exchanges of beneficial interests in the Bonds may be effected only through records maintained by DTC or its nominee. Settlement and secondary trading in the Bonds will be in same-day funds. Payments of principal and interest on the Bonds will be made to DTC in immediately available funds as described in the attached prospectus. See "Description of Debt Securities--DTC Book-Entry Only System" and "--Same-Day Settlement and Payment" in the attached prospectus. PAYMENT OF PRINCIPAL AND INTEREST The Bonds will mature and the principal amount, together with interest accrued and unpaid thereon, will be payable on September 17, 2001 (the "Stated Maturity"). The Bonds will not be redeemable at any time prior to Stated Maturity and will not have the benefit of any sinking fund. The Bonds will bear interest at a rate per annum, reset quarterly, equal to three-month LIBOR (as defined below) plus seventeen basis points (.17%), as determined by the Calculation Agent (as defined below). Interest will be computed on the basis of a 360-day year and the actual number of days in the applicable Interest Period (as defined below). Interest is payable quarterly in arrears on March 15, June 15, September 15, and December 15 of each year, commencing September 15, 1999, except that the final payment of interest will be due on September 17, 2001, instead of September 15, 2001 (each an "Interest Payment Date"), for the period commencing on and including the immediately preceding Interest Payment Date and ending on and including the day preceding the next Interest Payment Date (each an "Interest Period"), with the exception that the first Interest Period shall commence on and include August 27, 1999. Interest is payable to the persons in whose names the Bonds are registered at the close of business on the fifteenth calendar day, whether or not a Business Day (as defined below), prior to the Interest Payment Date. S-5 6 The interest rate on the Bonds may not exceed the "Maximum Rate", which is defined to mean the rate of interest equal to 15% per annum of such higher rate as may be established from time to time by the Board of Directors of the Company. If any Interest Payment Date, other than at Stated Maturity, for the Bonds would otherwise be a day that is not a Business Day, such Interest Payment Date will be postponed to the next day that is a Business Day, except that if such Business Day is in the next succeeding calendar month, such Interest Payment Date shall be the immediately preceding Business Day. If the Stated Maturity for the Bonds falls on a day which is not a Business Day, payment of principal and interest with respect to the Bonds will be paid on the next succeeding Business Day with the same force and effect as if made on such date and no interest on such payment will accrue from and after such date. The interest rate for each Interest Period will be determined by the Calculation Agent in accordance with the following provisions: The per annum rate of interest for each Interest Period will be three-month LIBOR on the second Business Day preceding the relevant Interest Reset Date (as defined below) for such Interest Period (the "Interest Determination Date") plus the applicable spread described above. The Interest Determination Date for the first Interest Period will be August 25, 1999. "LIBOR" for each subsequent Interest Period will be determined by the Calculation Agent in accordance with the following provisions: (i) On each Interest Determination Date, the Calculation Agent will ascertain the offered rate for three-month deposits in U.S. dollars in the London interbank market, which appears on the Telerate Page 3750, as of 11:00 a.m. (London time) on such Interest Determination Date. (ii) If such rate does not appear on the Telerate Page 3750, or the Telerate Page 3750 is unavailable, the Calculation Agent will request each of four major banks in the London interbank market (the "Reference Banks") to provide the Calculation Agent with its offered quotation (expressed as a rate per annum) for three-month deposits in U.S. dollars to leading banks in the London interbank market at approximately 11:00 a.m. (London time) on the Interest Determination Date. If at least two such quotations are provided, LIBOR in respect of the Interest Determination Date, will be the arithmetic mean of such quotations. (iii) If less than two of the Reference Banks provide the Calculation Agent with such offered quotations, LIBOR in respect of that Interest Determination Date will be the arithmetic mean of the rates quoted by three major banks in The City of New York (selected by the Calculation Agent) at approximately 11:00 a.m., New York City time, on that Interest Determination Date for three-month loans in U.S. dollars to leading European banks, in a principal amount equal to an amount of not less than $1,000,000 that is representative for a single transaction in such market at such time; provided, however, that if the banks selected as aforesaid by the Calculation Agent are not quoting as mentioned in this sentence, LIBOR will be LIBOR in effect on such Interest Determination Date. "Interest Reset Date" means, with respect to any Interest Period, the first day of such Interest Period. "Business Day" means any day (other than a Saturday or Sunday) on which banking institutions in The City of New York are open for business and which is also a London Banking Day. "London Banking Day" means any day (other than a Saturday or Sunday) on which dealings in deposits are transacted in the London interbank market. "Telerate Page 3750" means the display designated as page "3750" on the Bridge Telerate, Inc. (or such other page as may replace that page on that service for the purpose of displaying the LIBOR Index on a daily basis). All percentages resulting from any calculation on the Bonds will be rounded, if necessary, to the nearest one hundred-thousandth of a percentage point, with five one-millionths of a percentage point rounded upward (e.g., S-6 7 9.876545% (or .09876545) being rounded to 9.87655% (or .0987655)), and U.S. dollar amounts used in or resulting from such calculations will be rounded to the nearest cent (with one-half cent being rounded upward). The Company has agreed that, so long as any of the Bonds remain outstanding, it will maintain under appointment an agent (the "Calculation Agent"), initially Bankers Trust Company, to calculate the rate of interest payable on the Bonds in respect of each Interest Period. If the Calculation Agent is unable or unwilling to continue to act as such, or if the Calculation Agent fails to establish the applicable rate of interest for any Interest Period, or if the Company removes the Calculation Agent, the Company will appoint the office of another bank to act as the Calculation Agent; provided, however, that the Calculation Agent shall not resign or be removed until acceptance of an appointment by a successor as evidenced by an appropriate agreement entered into by the Company and such successor Calculation Agent. UNDERWRITING Subject to the terms and conditions stated in the underwriting agreement dated the date hereof, the Company has agreed to sell to Lehman Brothers Inc., as underwriter, and the underwriter has agreed to purchase from the Company, all of the Bonds. The underwriting agreement provides that the obligations of the underwriter to purchase the Bonds included in the offering are subject to approval of certain legal matters by counsel and to certain other conditions. The underwriter must purchase all the Bonds if it purchases any of the Bonds. The underwriter proposes to offer the Bonds directly to the public at the public offering price set forth on the cover page of this prospectus supplement. After the initial offering of the Bonds to the public, the public offering price may be changed by the underwriter. The Company estimates that its total expense of the offering will be $75,000. The Company has agreed to indemnify the underwriter against certain liabilities, including liabilities under the Securities Act of 1993, or to contribute to payments the underwriter may be required to make in respect of any of those liabilities. The underwriter and its affiliates have from time to time provided, and may in the future provide, investment banking and other financing services to the Company and its affiliates. Delivery of the Bonds is expected on or about August 27, 1999, which will be the seventh business day following the date of pricing of the Bonds. Under Rule 15c6-1 of the SEC under the Exchange Act, trades in the secondary market generally are required to settle in three business days, unless the parties to any such trade expressly agree otherwise. Accordingly, purchasers who wish to trade Bonds on the pricing date or the next succeeding business day will be required, by virtue of the fact that the Bonds will initially settle in T+7, to specify an alternate settlement cycle at the time of any such trade to prevent a failed settlement. Purchasers of Bonds who wish to trade the Bonds on the pricing date or the next succeeding business day should consult their own advisor. LEGAL OPINIONS The validity of the Bonds will be passed upon for the Company by Christopher C. Nern, Esq., Vice President and General Counsel of the Company, and for the underwriter by Brown & Wood LLP. Brown & Wood LLP will rely upon the opinion of Mr. Nern as to matters of Michigan law.
