We are issuing these notes as part of a series of first mortgage bonds under our Indenture of Mortgage and Deed of Trust, dated as of October 1, 1937, as amended and supplemented. Please also refer to the indenture, which was filed as an exhibit to the registration statement of which this prospectus supplement forms a part. The indenture limits the aggregate principal amount of first mortgage bonds at anyone time outstanding to $1.1 billion. We may amend the indenture and increase this amount without consent of the holders of first mortgage bonds. We are offering the notes on a continuing basis. For each note we offer and sell, we will prepare a pricing supplement to this prospectus supplement and the accompanying prospectus. The pricing supplement wilI include the specific terms of the note to which it relates and may include modifications of or additions to the more general terms described in this prospectus supplement and the accompanying prospectus. The pricing supplement relating to a note will contain the folIowing important information: . purchase price of the notes, which may be a percentage of the aggregate principal amount . issue date . maturity date . interest rate . interest accrual date . redemption provisions, if any . other material terms not inconsistent with the indenture The following information applies to the notes that we are offering, unless we specify otherwise in the pricing supplement. Except as we discuss below, we will issue each note in book-entry form and not certificated form. The depositary for book-entry notes will initially be TIle Depository Trust Company. You can buy the notes in denominations of $1 000 or any larger amount equally divisible by $1 000. The notes will mature from nine months to 30 years from the date of issue. Unless we specify otherwise in a pricing supplement and make additional related disclosure, we will not offer the notes to United States alien holders. You are a United States alien holder if you are for United States federal income tax purposes: . a nonresident alien individual . a foreign corporation . a foreign partnership or . an estate or trust that in either case is not subject to United States federal income tax on a net income basis on income or gain from a note. Interest and Payment on the Notes Each note will bear interest at a fixed rate stated on the face of the note. Interest will be computed on the basis of a 360-day year of twelve 30-day months. We will make interest payments to note holders on March 1 and September 1 of each year or on the interest payment dates specified in the pricing supplement, and at maturity or upon earlier redemption. If any interest payment date, redemption date or maturity date does not fall upon a business day, we will make the payment on the next business day. A business day is any day, other than a Saturday or Sunday, on which banks in The City of New York are not required or authorized by law to close. If we payor provide for payment on the next business day, no interest will accrue on those amounts for the period from and ,after the interest payment date, redemption date or maturity date, as the case may , to the next business day. We will make payments of principal, premium, if any, and interest in respect of the notes in immediately available funds. We will make payments on book-entry notes to Cede & Co., the partnership nominee of The Depository Trust Company. The record date for the March 1 payment will be February 15, and the record date for the September 1 payment will be August 15. If we change the interest payment dates, we will indicate in the pricing supplement the new record dates. In order to receive interest payments on a note, you must hold the note on the applicable record date, whether or not the record date is a business day. We will begin paying interest on the first interest payment date after the notes have been issued, provided that the notes are issued before the applicable record date. Redemption of the Notes The notes may be subject to redemption, either mandatory or at our option, before they mature. The pricing supplement will indicate whether or not a note is subject to redemption and the terms of redemption, if any. If we decide to redeem the notes, you will receive at least 30 days' notice. Book-Entry System We will issue each note in book-entry fonn. and the following provisions will apply to all book- entry notes: The Depository Trust Company (DTC), New York, NY, will act as securities depositary for the notes. We will issue the notes as fully-registered securities registered in the name of Cede & Co. or such other name as DTC may request. We will issue one fully-registered security for each issue of the notes, each in the aggregate principal amount of the issue, and we will deposit the certificate with the corporate trustee to hold as agent for DTc. We and the trustee will treat Cede & Co. as the absolute owner of the notes for all purposes. Only direct participants may make purchases of notes under DTC's system. Upon a participant' purchase, DTC will enter a credit for the notes in its records under such participant s account. The ownership interest of each actual purchaser, the beneficial owner, is in turn recorded on the participant s records. Beneficial owners will not receive written confirmation from DTC of their purchase, but the participant through which the beneficial owner entered into the transaction is expected to send the beneficial owners written confirmation providing details of the transaction, as well as periodic statements of their holdings. Each participant will record transfers of ownership interests in the notes by making an entry on the participant's books. Beneficial owners will not receive certificates representing their ownership interests in the notes, except in the event that use of the book-entry system for the notes is discontinued. To facilitate subsequent transfers, all notes deposited with DTC are registered in the name DTC's partnership nominee, Cede & Co., or such other name as DTC may request. The deposit of notes with DTC and their registration in the name of Cede & Co. effect no change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the notes. DTC's records reflect only the identity of the direct participants to whose accounts the notes are credited, which mayor may not be the beneficial owners. The participants remain responsible for keeping account of their holdings on behalf of their customers. Conveyance of notices and other communications by DTC to direct participants, by direct participants to indirect participants, and by direct participants and indirect participants to beneficial owners will be governed by arrangements among them, subject to any statutory or regulatory requirements that may be in effect from time to time. We will send redemption notices to DTc. If we are redeeming less than all of the notes, DTC' practice is to determine by lot the amount of the interest of each direct participant in the issue to be redeemed. Neither DTC nor Cede & Co. will consent or vote with respect to the notes. Under its usual procedures, DTC will mail an omnibus proxy as soon as possible after the record date. The omnibus proxy assigns Cede & Co.'s consenting or voting rights to those direct participants to whose accounts the notes are credited on the record date, identified in a listing attached to the omnibus proxy. The paying agent will make principal and interest payments on the notes to Cede & Co. or such other nominee as DTC may request. DTC's practice is to credit direct participants ' accounts upon DTC's receipt of funds and corresponding detailed information from us or our agent on the payable date in accordance with their respective holdings shown on DTC's records. Payments by participants to beneficial owners will be governed by standing instructions and customary practices as is the case with securities held for the accounts of customers in bearer form or registered in street name. Payment by participants to beneficial owners is the responsibility of the participants and not DTC, any agents or us subject to any statutory or regulatory requirements in effect. Payment of principal and interest to Cede & Co. is our responsibility or the responsibility of our paying agents. Disbursement of these payments direct participants is the responsibility of DTC, and disbursement of these payments to the beneficial owners is the responsibility of participants. DTC may discontinue providing its services as securities depositary with respect to the notes at any time by giving reasonable notice to us or to our agent. In the event that this occurs and a successor securities depositary is not appointed, we will print and deliver certificated notes in exchange for the notes represented by the global securities held by DTc. We may decide to discontinue use of the system of book-entry transfers through DTC, or a successor securities depositary. In that event, we will print and deliver certificated notes in exchange for the notes represented by the global securities held by DTc. DTC is a limited-purpose trust company organized under the New York Banking Law, a "banking organization" within the meaning of the New York Banking Law, a member of the Federal Reserve System, a "clearing corporation" within the meaning of the New York Uniform Commercial Code, and a "clearing agency" registered pursuant to the provisions of Section 17 A of the Securities Exchange Act of 1934, as amended. DTC holds securities that its participants deposit with DTc. DTC also facilitates the settlement among its participants of securities transactions, such as transfers and pledges, in deposited securities through electronic computerized book-entry changes in participants' accounts, thereby eliminating the need for physical movement of securities certificates. Direct participants in DTC include securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. A number of DTC's direct participants, The New York Stock Exchange, Inc., the American Stock Exchange LLC, and the National Association of Securities Dealers, Inc. own DTc. Access to the DTC system is also available to indirect participants such as securities brokers and dealers, banks, trust companies and clearing corporations that clear transactions through or maintain a custodial relationship with a direct participant, either directly or indirectly. The rules applicable to DTC and its participants are on file with the Securities and Exchange Commission. Neither we, the trustee, any paying agent, nor the registrar for the notes will have any responsibility or liability for any aspect of the records relating to or payments made on account of beneficial ownership interests in a global security or for maintaining, supervising or reviewing 'any records relating to these beneficial ownership interests. Tax Defeasance Under current United States federal income tax law, defeasance under the indenture should be treated as a taxable exchange of the notes to be defeased for an interest in the defeasance trust. Accordingly, you would recognize gain or loss equal to the difference between your cost or other tax basis of the notes and the fair market value of your interest in the defeasance trust. You would thereafter be required to include in inconie your share of the income, gain or loss of the defeasance trust, which could be a different amount and includible in income at different times than would be the case in the absence of defeasance under the indenture. You should consult your own tax advisors as to the specific potential consequences to you of defeasance under the indenture. SUPPLEMENTAL PLAN OF DISTRIBUTION We are offering the notes on a continuing basis through the agents listed on the cover, each of which has agreed to use to its reasonable best efforts to solicit purchases of the notes. We have the right to accept offers to purchase notes and may reject any proposed purchase of the notes. The agents may also reject any offer to purchase notes. We will pay the agents a commission on any notes sold through the agents. The commission will range from 0.125% to 0.750% of the principal amount of the notes depending on the maturity of the notes. We may also sell notes to the agents who will purchase the notes as principals for their own accounts. Any such sale will be made at a discount to be agreed upon at the time of sale. Any notes the agents purchase as principal may be resold at the market price or at other prices determined by the agents at the time of resale. The agents may resell any notes they purchase to other brokers or dealers at a discount which may include all or part of the discount the agents received from us. The agents will purchase the notes at a price equal to 100% of the principal amount less a discount. Unless otherwise stated, the discount will equal the applicable commission on an agency sale of notes of the same maturity. We may sell notes directly to investors on our own behalf in those jurisdictions where we are authorized to do so. We will not pay any commissions on sales made directly by us, We may sell notes through agents other than the agents listed on the cover subject to certain conditions described in the selling agency agreement that we have entered into with the agents listed on the cover. The commission applicable to agency sales through any other agents will be the same as that applicable to agency sales through the agents listed on the cover. The agents, whether acting as agents or principals, may be deemed to be "underwriters" within the meaning of the Securities Act of 1933, as amended. We have agreed to indemnify each agent against certain liabilities, including liabilities under the Securities Act or to contribute to payments made in respect of such liabilities. We have also agreed to reimburse the agents for certain of the agents expenses, including the reasonable fees and expenses of their counsel. The agents may sell to dealers who may resell to investors and the agents may pay all or part of the discount or commission they receive from us to the dealers. Such dealers may be deemed to be underwriters" within the meaning of the Securities Act of 1933. Any discounts or commissions that an agent receives in purchasing a note as principal and reselling such note, and any profit on the resale of such note by the agent, may be deemed to be underwriters' discounts or commissions under the Securities Act of 1933. Payment of the purchase price of the notes must be made in immediately available funds. In addition to offering the notes through the agents described in this prospectus supplement, we may sell other debt securities and preferred stock. Under certain circumstances, the sale of other debt securities or preferred stock may reduce the maximum aggregate amount of notes that we offer by this prospectus supplement. The notes are a new issue of securities with no established trading market and will not be listed on a securities exchange. The agents have advised us that they intend to establish a trading market for the notes. However, the agents are not obligated to do so and may discontinue any market maldng at any time without notice. No assurance can be given as to the liquidity of the trading market for the notes. In connection with the offering, the agents may purchase and sell notes in the open market. These transactions may include short sales, stabilizing transactions and purchases to cover positions created by short sales. Short sales involve the sale by the agents of a greater number of notes than they are required to purchase in the offering. Stabilizing transactions consist of certain bids or purchases made for the purpose of preventing or retarding a decline in the market price of the notes while the offering is in progress. The agents also may impose a penalty bid. This occurs when a particular agent repays to agents a portion of the underwriting discount received by it because the agents have repurchased notes sold by or for the account of such agent in stabilizing or short covering transactions. These activities by the agents may stabilize, maintain or otherwise affect the market price of the notes. As a result, the price of the notes may be higher than the price that otherwise might exist in the open market. If these activities are commenced, they may be discontinued by the agents at any time. We estimate that our share of the total expenses of the offering, excluding underwriting discounts and commissions, will be approximately $300 000. Each agent and its affiliates may from time to time engage in transactions with, and perform investment banking, general banking and other financial services for, us and our affiliates in the ordinary course of business. We may distribute this prospectus supplement and any applicable pricing supplement both by mail in printed form, and electronically, in portable document format. The prospectus supplement, the accompanying prospectus and any applicable pricing supplement may be made available in electronic format on the websites maintained by one or more of the agents. Other than the prospectus supplement, the accompanying prospectus and any applicable pricing supplement in electronic format the information on any of these websites and any other information contained on a website maintained by an agent is not part of this prospectus supplement, the accompanying prospectus and any applicable pricing supplement.

We have amended and supplemented this indenture in the past and will supplement it again by one or more supplemental indentures relating to these first mortgage bonds. This section briefly summarizes the material provisions of the indenture and uses some terms that are not defined in this prospectus but that are defined in the indenture. This summary is not complete. The indenture is on file with the Securities and Exchange Commission, and we incorporate it by reference in this prospectus. You should read the indenture for a complete understanding of its provisions and for the definitions of some terms used in this summary. We issue bonds in series. Each series of honds may have different terms. We will include all of the following information about a specific series of bonds in the prospectus supplement relating to those bonds: . the designation and series of the bonds . the aggregate principal amount of the bonds . the offering price of the bonds . the date or dates on which the bonds will mature . the interest rate or rates for the bonds, or how we will determine the interest rate or rates . the dates on which we will pay the interest on the bonds . the denominations in which we may issue the bonds . the terms pursuant to which we may redeem the bonds, if any . whether we will issue all or a portion of the bonds in global form and . any other terms or provisions relating to the bonds that are not inconsistent with the provisions of the indenture.

Section 38; Second Supplementa~ Section Improvement or Sinking Fund.There is no sinking or improvement fund requirement. Security. The indenture secures all bonds issued under the indenture equally and ratably, without preference, priority or distinction. We may issue additional first mortgage bonds in the future, and those first mortgage bonds will also be secured by the indenture. In the opinion of our general counsel the lien of the indenture constitutes a first mortgage on all the properties that we own, except as discussed below, subject only to liens for taxes and assessments that are not delinquent and minor excepted encumbrances. Certain of our properties are subject to easements, leases, contracts, covenants compensation awards and similar encumbrances and minor defects and clouds common to properties. In the opinion of our general counsel, none of these interferes with our operations. The indenture does not create a lien on the following excepted property: . revenues or profits, or notes or accounts receivable, contracts or chases in action, except as permitted by law during a completed default . securities or cash, except when pledged or . merchandise or equipment manufactured or acquired for resale. The indenture creates a lien on our interest in property that we subsequently acquire other than excepted property, subject to limitations in the case of consolidation, merger or sale of substantially all our assets. Indenture, Section 87 We have covenanted to execute and deliver instruments that are necessary to carry out the purposes of the indenture and to create a lien on after-acquired property that the indenture covers. Granting Clauses The indenture does not contain any covenants or other provisions to provide holders of the first mortgage bonds special protection in the event of a highly leveraged transaction. Issuance of Additional Bonds. The indenture limits the aggregate principal amount of bonds at anyone time outstanding to $1.1 billion. We may amend the indenture and increase this amount without consent of the holders of first mortgage bonds. Indenture, Sections 22 and 121; Thirty-eighth Supplemental, Article W The indenture contains some restrictions on increasing the amount of prior lien bonds. Indenture. Section We may issue additional bonds that rank equally with the bonds in principal amount equal to: . 60% of the cost or fair value, whichever is less, of property additions made after December 31 1943, less the amount of prior lien bonds thereon Indenture, Article J( Second Supplementa~ Section 13 . the principal amount of first mortgage bonds or prior lien bonds referred to above, retired or then to be retired Indenture, A/tides Vand VI or . the amount of cash that we deposit with the corporate trustee for the purpose, which we may withdraw on the same basis as bonds may be issued Indenture, Article VII. We may not issue bonds as provided above, with certain exceptions, unless we meet a net earnings requirement. Generally, the indenture requires that our net earnings must be at least twice the annual interest requirements on all outstanding debt of equal or prior rank, including the bonds that we propose to issue. Under certain circumstances, the net earnings test does not apply, including the issuance of refunding bonds to retire outstanding bonds which mature in less than two years or which are of an equal or higher interest rate, or prior lien bonds. We calculate net earnings before deduction of: . property retirement expenses, depreciation or depletion . interest expense on indebtedness . amortization of debt discount and expense and . any taxes measured by or dependent on net income. We may include only a limited amount of revenue from property not subject to the lien of the indenture in net earnings. Indenture, Sections 7, 27 and Article VI Property additions consist of electric or gas property, or property used in connection therewith. Property additions exclude securities, contracts or choses in action, merchandise and equipment for consumption or resale, materials and supplies, property used principally for production or gathering of natural gas, or any power sites and uncompleted works under Idaho state permits. In determining net property additions, we deduct all retired funded property from gross property additions except to the extent of certain credits respecting released funded property. Indenture, Section 4 The indenture restricts issuance of bonds and taking other credits under the indenture based on property additions subject to prior liens to no more than 15% of all bonds outstanding. However, the prior liens must not exceed 50% of the cost or fair value, whichever is less, of these property additions. Indenture, Section As of September 30, 2004, we could issue under the indenture approximately $677 million of additional first mortgage bonds based on unfunded property additions and $392 million of additional first mortgage bonds based on retired first mortgage bonds. We estimate that at September 30, 2004, unfunded property additions were approximately $1.1 billion.

Indenture, Section Amendment of the Indenture. Generally we may modify or amend the indenture with the consent of the holders of 60% in principal amount of all outstanding first mortgage bonds. However, when an amendment does not affect all series of first mortgage bonds, holders of 60% of the principal amount of all outstanding first mortgage bonds of each series affected must also consent to the amendment. Unless each bondholder consents, we cannot make the following modifications: . impair the right of any bondholder to receive payment on its bond when due or to sue for any overdue payment . create any lien equal or prior to the lien of the indenture . deprive any bondholder of a lien upon the mortgaged and pledged property or . reduce the bondholder vote necessary to amend the indenture.
