General
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. You should read the following information, which summarizes certain terms of the notes, in conjunction with the general terms and conditions of the notes and the indenture described under “Description of First Mortgage Bonds” in the accompanying prospectus.
We may offer these notes in any combination in one or more offerings up to an aggregate principal amount of $2,100,000,000. For each note we offer and sell, we will prepare a pricing supplement to this prospectus supplement and the accompanying prospectus. The pricing supplement will 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 following 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, and |
| • | 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 discussed under “Book-Entry System” in the accompanying prospectus, each note will be in book-entry form and not certificated form. The initial depository for book-entry notes will be The Depository Trust Company.
You may buy the notes in denominations of $1,000 or any larger amount equally divisible by $1,000.
Unless we specify otherwise in a pricing supplement and make additional related disclosure, we will not offer the notes to holders that are not either United States holders (as defined under “Material United States Federal Income Tax Considerations” below) or partnerships formed under the laws of the United States.
The Indenture of Mortgage and Deed of Trust, dated as of October 1, 1937, as amended and supplemented, including by the Fifty-third Supplemental Indenture, dated as of the date hereof, limits the aggregate principal amount of bonds at any one time outstanding to $5.5 billion. We may amend the indenture and increase or decrease this amount (but not below the amount of bonds at the time outstanding thereunder) without consent of the holders of first mortgage bonds.
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 noteholders 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.
S-1
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 pay or 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 be, 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.
S-2
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 offer to purchase 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. Unless otherwise specified in the pricing supplement, the commission will range from 0.150% to 0.875% 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 principal 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 a fixed public offering price, the market price or other prices determined by the agents at the time of resale.
The agents may resell any notes they purchase as principal to other brokers or dealers at a discount which may include all or part of the discount the agents received from us. Unless the applicable pricing supplement states otherwise, the agents will purchase the notes, as principal, at a price equal to 100% of the principal amount less a discount that equals the applicable commission on an agency sale of notes of the same maturity.
We may also 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 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 agent or as principal, 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 of 1933, or to contribute to payments made in respect of such liabilities. We have also agreed to reimburse the agents for certain of their 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.
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 making 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.
S-3
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.
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.
In addition, in the ordinary course of their business activities, the agents and their affiliates may make or hold a broad array of investments and actively trade debt and equity securities (or related derivative securities) and financial instruments (including bank loans) for their own account and for the accounts of their customers. Such investments and securities activities may involve securities and/or instruments of ours or our affiliates. If any of the agents or their affiliates have a lending relationship with us, certain of those agents or their affiliates routinely hedge, and certain other of those agents or their affiliates may hedge, their credit exposure to us consistent with their customary risk management policies. Typically, these agents and their affiliates would hedge such exposure by entering into transactions which consist of either the purchase of credit default swaps or the creation of short positions in our securities, including potentially the notes offered hereby. Any such credit default swaps or short positions could adversely affect future trading prices of the notes offered hereby. The agents and their affiliates may also make investment recommendations and/or publish or express independent research views in respect of such securities or financial instruments and may hold, or recommend to clients that they acquire, long and/or short positions in such securities and instruments.
S-4
MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS
The following is a summary of material United States federal income tax consequences of the purchase, ownership and disposition of the notes by United States holders (as defined below). Except as otherwise discussed below under “—Tax Defeasance”, this summary assumes that we will not defease the notes. It is included for general information only and does not address every aspect of the income or other tax laws that may be relevant to investors in the notes in light of their personal circumstances or that may be relevant to certain types of investors subject to special treatment under United States federal income tax laws (for example, financial institutions, former citizens or residents of the United States, tax-exempt organizations, insurance companies, real estate investment trusts, regulated investment companies, persons that are broker-dealers, traders in securities who elect the mark to market method of accounting for their securities, United States holders (as defined below) that have a functional currency other than the United States dollar, controlled foreign corporations, passive foreign investment companies, corporations that accumulate earnings to avoid United States federal income tax or investors in partnerships or other pass-through entities). In addition, this summary does not address the effect of United States federal alternative minimum tax, or any state, local or foreign tax laws that may be applicable to a particular holder and does not consider any aspects of United States federal tax law other than income taxation. This discussion is limited to initial purchasers of the notes issued pursuant to this prospectus supplement who purchase the notes for an amount of cash equal to their offering price and who hold the notes as capital assets under Section 1221 of the United States Internal Revenue Code of 1986, as amended (the “Code”) and not as part of a straddle, hedging, integrated, conversion or constructive sale transaction, or as part of a “synthetic security” or other similar financial transaction. Persons considering the purchase, ownership or disposition of the notes should consult their tax advisors concerning the United States federal tax consequences thereof in light of their particular situations as well as any consequences arising under the laws of any other taxing jurisdiction. Furthermore, the discussion below is based upon provisions of the Code, the legislative history thereof, existing and proposed United States Treasury regulations, administrative rulings and judicial decisions, all as of the date hereof. Such authorities may be repealed, revoked or modified (including changes in effective dates, and possibly with retroactive effect) so as to result in United States federal income tax consequences different from those discussed below. We have not sought and will not seek any rulings from the United States Internal Revenue Service (“IRS”) with respect to the matters discussed below. There can be no assurance that the IRS will not take a different position concerning the tax consequences of the purchase, ownership or disposition of the notes or that any such position would not be sustained.
For purposes of the following discussion, a “United States holder” means a beneficial owner of the notes that is, for United States federal income tax purposes:
| • | An individual citizen or resident of the United States; |
| • | A corporation (or other entity treated as a corporation for United States federal income tax purposes) created or organized in or under the laws of the United States, any state thereof or the District of Columbia; |
| • | An estate, the income of which is subject to the United States federal income tax regardless of source; or |
| • | A trust, if (a) a court within the United States is able to exercise primary supervision over administration of the trust and one or more United States persons have authority to control all substantial decisions of the trust or (b) it has a valid election in effect under applicable Treasury regulations to be treated as a domestic trust. |
If a partnership or an entity or arrangement treated as a partnership for United States federal income tax purposes owns any of the notes, the United States federal income tax treatment of a partner or an equity interest owner of such other entity will generally depend upon the status of the partner or owner and the activities of the partnership or other entity. If you are a partner of a partnership or an equity interest owner of another entity or arrangement treated as a partnership holding any of the notes, you should consult your tax advisor regarding the United States federal income tax consequences of the purchase, ownership and disposition of the notes.
S-5
Effect of Certain Contingencies
Treasury regulations provide special rules for the treatment of debt instruments that provide for contingent payments. Under these regulations, a contingency is disregarded if the contingency is remote or incidental, or, in certain circumstances, it is significantly more likely than not that such contingency will not occur. We intend to take the position that the contingencies on the notes, if any (for example, as described generally under “Description of the Notes—Redemption of the Notes”) will not cause the “contingent payment debt instrument” rules of the Treasury regulations to apply. Our determination that the notes are not contingent payment debt instruments is binding on a United States holder of notes unless such holder discloses a contrary position to the IRS in the manner required by the applicable Treasury regulations. Our determination is not, however, binding on the IRS. A successful challenge of this position by the IRS could adversely affect the timing and amount of income inclusions with respect to the notes, and could also cause any gain from the sale or other disposition of a note to be treated as ordinary income rather than as capital gain. United States holders of notes are encouraged to consult their own tax advisors regarding the possible application of the contingent payment debt instrument rules to the notes. The remainder of this summary assumes that the notes will not be considered to be contingent payment debt instruments.
Payments of Interest
If the notes are issued at a discount, any such discount is expected to be less than the statutorily defined de minimis amount of original issue discount and this summary assumes that the notes will not be issued with original issue discount for U.S. federal income tax purposes. Accordingly, interest on the notes generally will be taxable to a United States holder as ordinary interest income at the time it accrues or is received in accordance with the United States holder’s method of accounting for United States federal income tax purposes. The following discussion assumes the notes will be issued without, or with less than, the statutorily defined de minimis amount of original issue discount.
Sale, Exchange, Redemption or Other Taxable Disposition of Notes
Upon the sale, exchange, redemption or other taxable disposition of a note, a United States holder generally will recognize gain or loss equal to the difference between (1) the amount of cash and the fair market value of any property received on such disposition (less an amount equal to any accrued and unpaid stated interest, which will be taxable as interest income, as discussed above) and (2) such holder’s adjusted tax basis in such note. A United States holder’s adjusted tax basis in a note generally will equal the amount paid for the note less any principal repayments previously received by such holder. Gain or loss recognized by a United States holder in respect of the disposition generally will be capital gain or loss, and will be long-term capital gain or loss if the United States holder has held the note for more than one year at the time of such disposition. Long-term capital gains of certain noncorporate United States holders are entitled to reduced rates of taxation. The deductibility of capital losses is subject to limitations.
Additional Tax on Net Investment Income
United States holders that are not corporations generally will be subject to a 3.8% tax (the “Medicare tax”) on the lesser of (1) the United States holder’s “net investment income” for the taxable year and (2) the excess of the United States holder’s modified adjusted gross income for the taxable year over a certain threshold amount. A United States holder’s net investment income generally will include any income or gain recognized by such holder with respect to the notes, unless such income or gain is derived in the ordinary course of the conduct of such holder’s trade or business (other than a trade or business that consists of certain passive or trading activities). A United States holder that is not a corporation should consult its tax advisor regarding the applicability of the Medicare tax to its income and gains in respect of its investment in the notes.
S-6
Information Reporting and Backup Withholding
Payments of interest made by us on, or the proceeds of the sale or other disposition of, the notes may be subject to United States information reporting and may also be subject to United States federal backup withholding if the recipient of the payment fails to supply an accurate taxpayer identification number or otherwise fails to comply with applicable United States information reporting and certification requirements. Backup withholding is not an additional tax. Rather, any amount withheld under the backup withholding rules may be allowable as a refund or credit against the holder’s United States federal income tax, provided that the required information is timely furnished to the IRS.
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, a United States holder would recognize gain or loss equal to the difference between its cost or other tax basis of the notes and the fair market value of its interest in the defeasance trust. In addition, a United States holder would thereafter be required to include in income its 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. United States holders should consult their own tax advisors as to the specific potential consequences of defeasance under the indenture.
PROSPECTIVE INVESTORS ARE ADVISED TO CONSULT THEIR TAX ADVISORS CONCERNING THE APPLICATION OF THE UNITED STATES FEDERAL TAX LAWS TO THEIR PARTICULAR CIRCUMSTANCES AS WELL AS ANY TAX CONSEQUENCES ARISING UNDER THE LAWS OF ANY STATE, LOCAL OR FOREIGN TAXING JURISDICTION PRIOR TO MAKING SUCH INVESTMENT.

| • | advancement and adoption of self-generation, energy storage, energy efficiency, alternative energy sources, and other technologies that may reduce Idaho Power’s sale or delivery of electric power or introduce operational vulnerabilities to the power grid; |
| • | variable hydrological conditions and over-appropriation of surface and groundwater in the Snake River Basin, which may impact the amount of power generated by Idaho Power’s hydropower facilities and power supply costs; |
| • | ability to acquire equipment, materials, fuel, power, and transmission capacity on reasonable terms and prices, particularly in the event of unanticipated or abnormally high resource demands, price volatility (including as a result of new or increased tariffs), lack of physical availability, transportation constraints, outages due to maintenance or repairs to generation or transmission facilities, disruptions in the supply chain, or reduced credit quality or lack of counterparty and supplier credit; |
| • | inability to timely obtain and the cost of obtaining and complying with required governmental permits and approvals, licenses, rights-of-way, and siting for transmission and generation projects and hydropower facilities; |

| • | ability to enter into financial and physical commodity hedges with creditworthy counterparties to manage price and commodity risk for fuel, power, and transmission, and the failure of any such risk management and hedging strategies to work as intended, and the potential losses the companies may incur on those hedges, which can be affected by factors such as the volume of hedging transactions and degree of price volatility; |
4

DESCRIPTION OF FIRST MORTGAGE BONDS
As used under this caption, “Description of First Mortgage Bonds,” references to “we,” “us,” “our” and other similar references mean Idaho Power Company, excluding, unless otherwise expressly stated or the context otherwise requires, its subsidiary.
We will issue the first mortgage bonds offered in this prospectus under our Indenture of Mortgage and Deed of Trust, dated as of October 1, 1937. Deutsche Bank Trust Company Americas, formerly known as Bankers Trust Company, is the trustee. We have amended and supplemented the 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 supplemental indentures, which we refer to collectively as the indenture in this section, and uses some terms that are not defined in this prospectus but are defined in the indenture. This summary is not complete and we qualify it by reference to the indenture. The indenture is on file with the SEC, 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. In the summary below, we include references to section numbers of the indenture so that you can easily locate those provisions.
Our issuance of long-term indebtedness, including first mortgage bonds, is subject to the approval of the Idaho Public Utilities Commission (“IPUC”), the Public Utility Commission of Oregon (“OPUC”), and the Wyoming Public Service Commission (“WPSC”). In January 2024, we filed applications with the IPUC, OPUC, and WPSC to renew our debt financing authority. In February and March 2024, Idaho Power received orders from the IPUC, OPUC, and WPSC, authorizing the issuance and sale from time to time of up to $1.2 billion in aggregate principal amount of debt securities and first mortgage bonds, subject to conditions specified in the orders. Authority from the IPUC is through December 31, 2026, subject to extension upon request to the IPUC. The OPUC’s and WPSC’s orders do not impose a time limitation for issuances, but the OPUC order does impose a number of other conditions, including a maximum interest rate limit of 8.0 percent. As of the date of this prospectus, $900 million of capacity remains available under the IPUC, OPUC, and WPSC orders. We will file future applications with the IPUC, OPUC, and WPSC to renew our debt financing authority as necessary.
Issuance in Series. We issue bonds in series. Each series of bonds 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. |
Form and Exchange. Unless we state otherwise in the prospectus supplement:
| • | we will issue the bonds in fully registered form without coupons, |
7
| • | a holder of bonds may exchange bonds, without charge, for an equal aggregate principal amount of bonds of the same series, having the same issue date and with identical terms and provisions, and |
| • | a holder of bonds may transfer bonds, without charge, other than applicable stamp taxes or other governmental charges. |
See “Book-Entry System” for a description of additional requirements as to the form and method of exchange of bonds. We will describe any additional requirements as to the form and method of exchange of bonds in the prospectus supplement.
Interest and Payment. We will pay principal, premium, if any, and interest in U.S. dollars at Deutsche Bank Trust Company Americas in New York City, and, at our option, at our office in Boise, Idaho. Indenture, Section 35
Maintenance Requirements. We will file a certificate with the corporate trustee within 90 days after the close of each calendar year stating that:
| • | we have made the necessary expenditures to maintain our property in good condition as an operating system, or |
| • | we will designate an additional amount that should be spent for this purpose. |
If we designate an additional amount, we must deliver to the corporate trustee, within 30 days, cash equal to that amount less the following deductions:
| • | expenditures made after the close of the year to maintain the property, and |
| • | any allowances for waiver of our right to issue additional bonds under the indenture. Indenture, Section 38 |
We may withdraw this cash for reimbursement for later expenditures on:
| • | property maintenance, repairs, renewals and replacements, |
| • | waiver of our right to issue additional bonds under the indenture, or |
| • | the purchase or redemption of bonds of any series, unless a supplemental indenture provides otherwise for a particular series of bonds. |
We must spend or appropriate 15% of our annual gross operating revenues for maintenance, retirement or amortization of our properties. We may, however, anticipate or make up these expenditures or appropriations within the five years that immediately follow or precede a particular year. Indenture, Section 38; Second Supplemental, Section 15
Improvement or Sinking Fund. There is no sinking or improvement fund requirement. Twenty-seventh Supplemental, Section 14
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. 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, workmen’s compensation awards and similar encumbrances and minor defects and clouds common to properties, which do not interfere in any material respect with our operations.
8
The indenture does not create a lien on the following excepted property:
| • | revenues or profits, or notes or accounts receivable, contracts or choses 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 any one time outstanding to $3.5 billion. We may amend the indenture and increase this amount without consent of the holders of first mortgage bonds. Indenture, Sections 22 and 121; Fifty-first Supplemental, Article I
The indenture contains some restrictions on increasing the amount of prior lien bonds, which are bonds, obligations or principal indebtedness secured by any mortgage or other lien upon any property additions prior to the lien of the indenture. Indenture, Sections 6 and 46
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 V, Second Supplemental, Sections 10 and 13 |
| • | the principal amount of first mortgage bonds or prior lien bonds referred to above, retired or then to be retired, Indenture, Articles V and 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. |
9
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 with respect to 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 26
As of December 31, 2024, we could issue under the indenture approximately $2.2 billion of additional first mortgage bonds based on unfunded property additions and retired first mortgage bonds.
Release of Properties. Generally, we may release property from the lien of the indenture by doing the following:
| • | depositing cash with the corporate trustee, |
| • | substituting property additions, or |
| • | waiving our right to issue additional bonds on the basis of retired bond credits, without application of the net earnings test. Indenture, Section 59 |
Actions Without Trustee’s Release or Consent. Unless we are in default in the payment of interest on any outstanding bonds or one or more of the completed defaults described under the caption “Events of Default” below have occurred and are continuing, we may, without the trustee’s release or consent, and without providing a report to the trustee or depositing with it the consideration we receive:
| • | sell or otherwise dispose of any machinery, equipment, tools, implements or other property, which has become old, inadequate, obsolete, worn out, unfit or unadapted for use in our operations, after we replace that property with other property which has at least equal value and is subject to no additional liens, |
| • | cancel or make changes or alterations in or substitutions of any contracts, leases or rights of way grants, or |
| • | surrender or assent to the modification of any right, power, franchise, license, governmental consent or permit under which we may be operating, if, in the opinion of our board of directors, stated in a resolution filed with the corporate trustee, the surrender or modification is desirable in the conduct of our business and does not impair the security of outstanding bonds. Indenture, Section 58 |
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, |
10
| • | deprive any bondholder of a lien upon the mortgaged and pledged property, or |
| • | reduce the bondholder vote necessary to amend the indenture. Indenture, Sections 113, 121; Twenty-third Supplemental, Section 9; Thirty-sixth Supplemental, Section 9 |
Events of Default. The following are defaults, sometimes called completed defaults, under the indenture:
| • | failure to pay the principal of any bond when due and payable whether at maturity or otherwise, |
| • | failure to pay interest on any bond for 60 days, |
| • | failure to pay principal of or interest on any outstanding prior lien bond beyond the grace period, if any, in the prior lien bond, |
| • | failure to observe a covenant not to, without the trustee’s written approval: |
| • | go into voluntary bankruptcy or insolvency, apply for or consent to the appointment of a receiver or trustee for us or our property in any judicial proceedings or make any general assignment for the benefit of creditors, or |
| • | suffer to be made and remain unvacated for a period of 90 days any order for the appointment of a receiver or trustee for us or our property in any proceeding instituted by a creditor, or any final order appointing such a receiver or trustee in any other proceeding or any order adjudicating us to be bankrupt or insolvent, or |
| • | failure to perform other covenants, agreements or conditions contained in the indenture for 90 days after the trustee gives us notice. Indenture, Section 65 |
Discharge. The indenture will be cancelled and discharged when all indebtedness secured by the indenture is paid, including charges of the trustee.
In addition, first mortgage bonds will be considered paid and not to be outstanding for any purpose under the indenture when we have irrevocably deposited with the trustee
| • | sufficient cash, or |
| • | an amount of direct obligations of, or obligations guaranteed by, the United States government or obligations which are collateralized by obligations of the United States government which, in the opinion of an independent accountant and the opinion of our officers, will provide sufficient funds, without regard to reinvestment thereof, together with any deposited cash to pay when due the principal of, and premium, if any, and interest to the maturity date or redemption date of such first mortgage bonds, provided that in the case of redemption, proper notice shall have been given or appropriate arrangements have been made with the trustee for the giving of notice. Indenture, Section 106 and Twenty-seventh Supplemental, Section 10 |
Miscellaneous. The indenture provides that the trustee, upon request of the holders of a majority in interest of the outstanding first mortgage bonds, if properly indemnified to its satisfaction, must take action to enforce the lien of the indenture. Indenture, Section 92; Sixth Supplemental, Article XXIII
We covenant in the indenture to deliver a certificate to the trustee annually, within 90 days after the close of the fiscal year, to show that we are in compliance with the terms of the indenture and that we have not defaulted under the indenture. Various supplemental indentures
Concerning the Corporate Trustee. We and our affiliates may conduct banking transactions with the trustee in the normal course of business.

DESCRIPTION OF DEBT SECURITIES
As used under this caption, “Description of Debt Securities,” references to “we,” “us,” “our” and other similar references mean Idaho Power Company, excluding, unless otherwise expressly stated or the context otherwise requires, its subsidiary.
We will issue the debt securities offered in this prospectus under our Debt Securities Indenture, dated as of August 1, 2001. Deutsche Bank Trust Company Americas is the trustee under the indenture. We may amend and supplement the indenture and will supplement it by one or more supplemental indentures relating to these debt securities.
This section briefly summarizes the material provisions of the debt securities indenture and uses some terms that are not defined in this prospectus but are defined in the indenture. This summary is not complete and we qualify it by reference to the indenture. The indenture is on file with the SEC, and we incorporate it by reference in this prospectus. You should read the indenture for a complete understanding of its provisions and for the definition of some terms used in this summary. In the summary below, we include references to section numbers of the indenture so that you can easily locate these provisions.
As noted above, in January 2024, we filed applications with the IPUC, OPUC, and WPSC to renew our debt financing authority. In February and March 2024, Idaho Power received orders from the IPUC, OPUC, and WPSC, authorizing the issuance and sale from time to time of up to $1.2 billion in aggregate principal amount of debt securities and first mortgage bonds, subject to conditions specified in the orders. Authority from the IPUC is through December 31, 2026, subject to extension upon request to the IPUC. The OPUC’s and WPSC’s orders do not impose a time limitation for issuances, but the OPUC order does impose a number of other conditions, including a maximum interest rate limit of 8.0 percent. As of the date of this prospectus, $900 million of capacity remains available under the IPUC, OPUC, and WPSC orders. We will file future applications with the IPUC, OPUC, and WPSC to renew our debt financing authority as necessary.
Other Indebtedness. The indenture does not limit the amount of debt securities that we may issue; it does not restrict the amount or type of other debt that we may issue or contain any other provisions that would afford holders of the debt securities protection in the event of a highly leveraged transaction. We may use other indentures or documentation containing provisions different from those included in the indenture under which we are offering these debt securities in connection with future issues of debt securities. We may also offer our first mortgage bonds, which are secured indebtedness and which are described above under the caption “Description of First Mortgage Bonds.” As of December 31, 2024, there was approximately $3.1 billion in aggregate principal amount of our first mortgage bonds outstanding.
Security, Ranking and Subordination. The debt securities that we may issue under this indenture will be unsecured. The debt securities that we are offering in this prospectus will rank equal in right of payment to our other unsecured indebtedness that is outstanding now or that we may issue in the future, except for any indebtedness that, by its terms, is subordinate to these debt securities.
Issuance in Series. We will issue debt securities in series. Each series of debt securities may have different terms and, in some cases, debt securities of the same series may have different terms. The prospectus supplement relating to a particular series of debt securities will contain the following information about those debt securities:
| • | the title of the series, |
| • | any limit on the aggregate principal amount of the series, |
| • | the date or dates on which we will issue the debt securities of that series and on which we will pay the principal amount and any premium, |
| • | the rate or rates at which the debt securities of that series will bear interest, or how we will determine the rate or rates, |
12
| • | the date or dates from which interest will accrue, |
| • | the dates on which we will pay interest on the debt securities of that series and the regular record dates for the interest payment dates, |
| • | the place or places where we will pay the principal of, premium, if any, and interest, if different from those we describe in this prospectus, |
| • | any redemption terms, including mandatory redemption through a sinking fund or otherwise, redemption at our option and redemption at the option of the holder, |
| • | the denominations in which we will issue the debt securities of that series, if other than denominations of $1,000 and any integral multiple of $1,000, |
| • | the provisions for the satisfaction and discharge of the indenture if different from those we describe in this prospectus, and |
| • | any other terms of the debt securities of the series. |
Form and Exchange. Unless we state otherwise in the prospectus supplement:
| • | we will issue the debt securities in fully registered form without coupons, |
| • | a holder of debt securities may exchange debt securities, without charge, for an equal aggregate principal amount of debt securities of the same series, having the same issue date and with identical terms and provisions, and |
| • | a holder of debt securities may transfer debt securities, without charge, other than applicable stamp taxes or other governmental charges. Indenture, Sections 3.1, 3.2 and 3.6 |
Unless we state otherwise in the prospectus supplement, the transfer of debt securities may be registered and exchanged at the corporate trust office of the trustee, in New York, New York, as security registrar. We may change the place for registration of transfer and exchange. We may designate one or more additional places for registration and exchange, all at our discretion.
We are not required to execute or to provide for the registration of transfer or exchange of any debt security
| • | during a period of 15 days prior to giving any notice of redemption with respect to that debt security, or |
| • | that has been selected for redemption in whole or in part, except the unredeemed portion of any debt security being redeemed in part. Indenture, Sections 3.6 and 4.2 |
See “Book-Entry System” for a description of additional requirements as to the form and method of exchange of debt securities. We will describe any additional requirements as to the form and method of exchange of debt securities in the prospectus supplement. Indenture, Section 3.1
Payment of Interest. Unless we state otherwise in the prospectus supplement, we will pay interest on each debt security to the person in whose name the debt security is registered as of the close of business on the regular record date for that interest payment date. If we have defaulted in the payment of interest on any debt security, we may pay the defaulted interest to the holder of the debt security as of the close of business on a special record date that is not less than 10 days prior to the date we propose to pay the defaulted interest. Notice of the special record date will be given by mail at least 15 days before the special record date. We may also pay defaulted interest in any other lawful manner permitted by requirements of any securities exchange on which the debt security may be listed, if the trustee deems that manner of payment practicable. Indenture, Section 3.8
Unless we state otherwise in the prospectus supplement, we will pay the principal of and premium, if any, and interest at maturity at the corporate trust office of the trustee, in New York, New York, as our paying agent. We
13
may change the place of payment. We may appoint one or more additional paying agents and may remove any paying agent, all at our discretion. Indenture, Section 4.2
Redemption. We will describe any terms for the optional or mandatory redemption of a particular series of debt securities in the prospectus supplement. Unless we state in the prospectus supplement that the debt securities of that series are redeemable at the option of a holder, debt securities will be redeemable only at our option. In order to exercise our right to redeem any debt security, we must give the holder notice by mail at least 30 days prior to the date fixed for redemption. If we want to redeem fewer than all the debt securities of a series, the trustee will choose the particular debt securities to be redeemed by a method of random selection, substantially pro rata, that the trustee believes is fair and appropriate and which complies with the requirements of the principal national securities exchange, if any, on which the debt securities of that series are listed. If the debt securities to be redeemed have different terms and different maturities, we may select the particular debt securities to be redeemed.
Unless we state otherwise in the prospectus supplement, if we are redeeming the debt securities at our option, the redemption will be conditional upon the paying agent or agents receiving from us, on or prior to the date fixed for redemption, enough money to redeem all of the debt securities called for redemption, including accrued interest, if any. If sufficient money has not been received, the notice will not be effective and we will not be required to redeem the debt securities. Indenture, Section 14.2
Consolidation, Merger or Sale. The indenture provides that we will not consolidate with, merge with or into any other person, whether or not we are the survivor, or sell, assign, transfer or lease all or substantially all of our properties and assets as an entirety or substantially as an entirety to any person or group of affiliated persons, in one transaction or a series of related transactions, unless:
| • | the successor person, if we are not the survivor, is a person organized under the laws of the United States or any state thereof or the District of Columbia and expressly assumes in writing, by a supplemental indenture, all of our obligations under the outstanding debt securities and the indenture, |
| • | immediately before and after giving effect to the transaction or series of transactions, no event of default, and no default, shall have occurred and be continuing, and |
| • | we deliver to the trustee an officer’s certificate and an opinion of counsel stating that the transaction and the supplemental indenture comply with the indenture. Indenture, Article Eleven |
Events of Default. The following are events of default with respect to any series of debt securities:
| • | failure to pay the principal of, or premium, if any, on, any debt security of that series when due and payable at maturity, and upon redemption, and the time for payment has not been extended or deferred, but excluding any failure by us to deposit money in connection with any redemption that is at our option, |
| • | failure to pay interest on any debt security of that series when due and our failure continues for 30 days, and the time for payment has not been extended or deferred, |
| • | failure to make a sinking fund payment when due with respect to debt securities of that series, |
| • | failure to observe or perform any other covenant, warranty or agreement contained in the debt securities of that series or in the indenture, other than a covenant, agreement or warranty included in the indenture that is specifically dealt with in another event of default, and our failure continues for 60 days after the trustee or holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series have given us written notice, |
| • | a court enters a decree or order for relief that remains unstayed and in effect for 60 consecutive days in respect of us in an involuntary case under any applicable bankruptcy, insolvency or similar law: |
14
| • | appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official for us or for any substantial part of our property, or |
| • | ordering the winding up or liquidation of our affairs, |
| • | we commence a voluntary case under any applicable bankruptcy, insolvency or similar law, |
| • | we consent to the entry of an order for relief in an involuntary case under any applicable bankruptcy, insolvency or similar law, |
| • | we consent to the appointment or taking possession by a receiver, liquidator, assignee, custodian, trustee, sequestrator or similar official for us or for any substantial part of our property, |
| • | we make any general assignment for the benefit of creditors, and |
| • | any other event of default with respect to debt securities of that series specified in the applicable prospectus supplement. Indenture, Section 6.1 |
An event of default with respect to the debt securities of any series does not necessarily constitute an event of default with respect to any other series of debt securities issued under the indenture. Unless we cure the default, the trustee is required to give notice of any default known to it within 90 days after the default has occurred; the term “default” includes any event which after notice or passage of time or both would be an event of default. Except in the case of a default in payment, the trustee is protected in withholding notice if and so long as the board of directors, the executive committee or a trust committee of directors or responsible officers of the trustee in good faith determine that the withholding of notice is in the interest of the holders. Indenture, Section 6.11
If an event of default with respect to debt securities of any series, other than due to events of bankruptcy, insolvency or reorganization, occurs and is continuing, the trustee or the holders of at least 25% in aggregate principal amount of the outstanding debt securities of that series, by notice in writing to us, and to the trustee if given by the holders, may declare the unpaid principal of and accrued interest to the date of acceleration on all the outstanding debt securities of that series to be due and payable immediately. The holders of a majority of the principal amount of the outstanding debt securities of that series, upon the conditions provided in the indenture, may rescind an acceleration and its consequences with respect to that series.
If an event of default occurs due to bankruptcy, insolvency or reorganization, all unpaid principal of and accrued interest on the outstanding debt securities of all series will become immediately due and payable without any declaration or other act on the part of the trustee or any holder. Indenture, Section 6.1
The holders of a majority in principal amount of the outstanding debt securities of any series will have the right to direct the time, method and place of conducting any proceeding for any remedy available to the trustee, or exercising any trust or power conferred on the trustee, with respect to the debt securities of that series, subject to the right of the trustee to decline to follow instructions that would be unlawful, expose the trustee to personal liability or be unduly prejudicial to the interests of holders who do not join in the direction. Indenture, Section 6.9
Subject to the provisions of the indenture relating to the duties of the trustee, if an event of default shall occur and be continuing, the trustee will be under no obligation to exercise any of its rights or powers under the indenture at the request or direction of any of the holders, unless the holders have offered to the trustee reasonable indemnity. Indenture, Section 7.2
The indenture provides that we must periodically file statements with the trustee regarding compliance by us with all conditions and covenants contained in the indenture. Indenture, Section 4.6
Modification of Indenture. We may modify the indenture, without notice to or the consent of any holders of debt securities, with respect to certain matters, including:
15
| • | to add one or more covenants or other provisions for the benefit of holders of debt securities of one or more series or to surrender any of our rights or powers, and |
| • | to cure any ambiguity, defect or inconsistency or to correct or supplement any provision which may be inconsistent with any other provision of the indenture. Indenture, Section 10.1 |
In addition, we may modify certain of our rights and obligations and the rights of holders of the debt securities with the consent of the holders of at least a majority in aggregate principal amount of the outstanding debt securities affected by the modification. Indenture, Section 10.2
No amendment or modification may, without the consent of each holder of any outstanding debt security affected:
| • | change the stated maturity of any debt security, |
| • | reduce the principal amount of, or the rate of interest on, or the amount of any premium on, or any amount payable on redemption of, or extend the time for payment or change the method of calculating interest on, any debt security, or reduce the amount of principal of an original issue discount security that would be due and payable upon acceleration of maturity, |
| • | impair the right to institute suit for the enforcement of any payment with respect to any debt security, |
| • | reduce the percentage in principal amount of outstanding debt securities of any series necessary to modify or amend the indenture, or to waive compliance with certain provisions of the indenture or defaults or events of default and their consequences, or |
| • | subordinate any debt securities to any other of our indebtedness. Indenture, Section 10.2 |
Waiver. The holders of not less than a majority in aggregate principal amount of the outstanding debt securities of any series may waive any default or event of default with respect to that series, except payment and bankruptcy defaults. Indenture, Section 6.10
Defeasance. Unless we state otherwise in the prospectus supplement relating to the debt securities of a particular series, the indenture provides that we shall be discharged from our obligations under the indenture with respect to any series of debt securities at any time prior to the maturity date or redemption of that series when we meet certain requirements specified in the indenture, including
| • | when we have irrevocably deposited in trust with the trustee: |
| • | sufficient funds to pay the principal of and premium, if any, and interest to the maturity date or redemption on, the debt securities of that series, or |
| • | an amount of direct obligations of, or obligations guaranteed by, the United States government as will be sufficient, without consideration of any reinvestment of any accrued income on those obligations, to pay when due the principal of and premium, if any, and interest to the maturity date or redemption on, the debt securities of that series, and |
| • | when we have paid all other sums payable with respect to the debt securities of that series. |
Upon the discharge of the indenture with respect to a particular series, the holders of debt securities of that series shall no longer be entitled to the benefits of the indenture, except for purposes of registration of transfer, exchange and replacement of lost, stolen or mutilated debt securities. Indenture, Sections 12.1 and 12.2
Concerning the Trustee. We and our affiliates may conduct banking transactions with the trustee or its affiliates in the normal course of business.
16
We may issue all or some of the first mortgage bonds and debt securities in book-entry form, which means that global notes, not certificates, will represent the securities. If we issue global notes representing any securities, the following provisions will apply to all book-entry securities:
Unless otherwise indicated in the applicable prospectus supplement, the Depository Trust Company, New York, NY, which we refer to as “DTC,” will act as securities depository for the securities. We will issue the securities as fully-registered securities registered in the name of Cede & Co., DTC’s partnership nominee, or such other name as may be requested by an authorized representative of DTC. We will issue one or more fully-registered security certificates for each issue of the securities, in the aggregate principal amount of the issue, and we will deposit the certificates with the corporate trustee to hold as agent for DTC. We and the trustee will treat Cede & Co. as the holder of the securities for all purposes.
DTC has informed us that it 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 17A of the Securities Exchange Act of 1934, as amended. DTC also facilitates the post-trade settlement among direct participants of sales and other securities transactions in deposited securities through electronic computerized book-entry transfers and pledges between direct participants’ accounts. This eliminates the need for physical movement of securities certificates. Direct participants include both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, clearing corporations, and certain other organizations. DTC is a wholly-owned subsidiary of The Depository Trust & Clearing Corporation, or DTCC. DTCC is the holding company for DTC, National Securities Clearing Corporation and Fixed Income Clearing Corporation, all of which are registered clearing agencies. DTCC is owned by the users of its regulated subsidiaries. Access to the DTC system is also available to others such as both U.S. and non-U.S. securities brokers and dealers, banks, trust companies, and clearing corporations that clear through or maintain a custodial relationship with a direct participant, either directly or indirectly. The DTC rules applicable to its participants are on file with the SEC. More information about DTC can be found at www.dtcc.com and www.dtc.org.
Purchases of securities under the DTC system must be made by or through direct participants, which will receive a credit for the securities on DTC’s records. The ownership interest of each actual purchaser, the beneficial owner, is in turn to be recorded on the direct and indirect participants’ records. Beneficial owners will not receive written confirmation from DTC of their purchase. Beneficial owners are, however, expected to receive written confirmations providing details of the transaction, as well as periodic statements of their holdings, from the direct or indirect participant through which the beneficial owner entered into the transaction. Transfers of ownership interests in the securities are to be accomplished by entries made on the books of direct and indirect participants acting on behalf of beneficial owners. Beneficial owners will not receive certificates representing their ownership interests in the securities, except in the event that use of the book-entry system for the securities is discontinued.
To facilitate subsequent transfers, all securities deposited with DTC are registered in the name of DTC’s partnership nominee, Cede & Co., or such other name as may be requested by an authorized representative of DTC. The deposit of securities with DTC and their registration in the name of Cede & Co. or such other DTC nominee do not effect any change in beneficial ownership. DTC has no knowledge of the actual beneficial owners of the securities. DTC’s records reflect only the identity of the direct participants to whose accounts the securities are credited, which may or may not be the beneficial owners. The direct and indirect participants will 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.
17
Redemption notices will be sent to DTC. If less than all of the securities within an issue are being redeemed, DTC’s 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., nor any other DTC nominee, will consent or vote with respect to the securities unless authorized by a direct participant in accordance with DTC’s money market instrument procedures. Under its usual procedures, DTC mails an omnibus proxy to the issuer 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 securities are credited on the record date, identified in a listing attached to the omnibus proxy.
Redemption proceeds and distributions, including principal and interest payments, on the securities will be made to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC. DTC’s practice is to credit direct participants’ accounts upon DTC’s receipt of funds and corresponding detail information from us or the trustee 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 will be the responsibility of the participants and not of DTC, the trustee or us, subject to any statutory or regulatory requirements as may be in effect from time to time. Payment of redemption proceeds and distributions to Cede & Co., or such other nominee as may be requested by an authorized representative of DTC, is our responsibility or the responsibility of the trustee. Disbursement of such payments to direct participants will be the responsibility of DTC, and disbursement of such payments to the beneficial owners will be the responsibility of direct and indirect participants.
In case of any optional tender for or mandatory purchase of securities, pursuant to their terms, a beneficial owner shall give notice to elect to have its securities purchased or tendered through its participant to the tender/remarketing agent and shall effect delivery of the securities by causing the direct participant to transfer the participant’s interest in the securities, on DTC’s records, to the tender/remarketing agent. The requirement for physical delivery of securities in connection with an optional tender or a mandatory purchase will be deemed satisfied when the ownership rights in the securities are transferred by direct participants on DTC’s records and followed by a book-entry credit of tendered securities to the tender/remarketing agent’s DTC account.
DTC may discontinue providing its services as depository with respect to the securities at any time by giving reasonable notice to us. Under such circumstances, in the event that a successor depository is not obtained, security certificates are required to be printed and delivered.
We may decide to discontinue use of the system of book-entry-only transfers through DTC, or a successor securities depository. In that event, security certificates will be printed and delivered to DTC.
Neither we, the trustee, any paying agent, nor the registrar for the securities 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.
The information in this section concerning DTC and DTC’s book-entry system has been obtained from sources that we believe to be reliable, but we take no responsibility for the accuracy thereof.
The underwriters, dealers or agents of any of the securities may be direct participants of DTC.
18
Unless we state otherwise in the prospectus supplement, we will add the net proceeds from the sale of the securities to our general funds. We may use our general funds for any of the following purposes:
| • | to acquire property, |
| • | to construct, complete, extend or improve our electric facilities, |
| • | to improve or maintain our service, |
| • | to redeem, pay at maturity or purchase outstanding first mortgage bonds and debt securities, |
| • | to repay short-term borrowings, or |
| • | for other general corporate purposes. |
The precise amount and timing of the application of such proceeds will depend on our funding requirements, market conditions and the availability and cost of other funds. If we do not use the proceeds immediately, we may temporarily invest them in short-term instruments.
19
Methods of Offer and Sale
We may sell the securities offered by this prospectus:
| • | through underwriters or dealers, |
| • | through agents, |
| • | directly to one or more purchasers, or |
| • | through a combination of any of the above methods of sale. |
Through Underwriters or Dealers. If we use underwriters in the sale, the underwriters will buy the securities for their own account. The underwriters may resell the securities in one or more transactions, including negotiated transactions, at a fixed public offering price or at varying prices determined at the time of the sale. The underwriters may sell the securities directly or through underwriting syndicates that managing underwriters represent. Unless we state otherwise in the prospectus supplement, the obligations of the underwriters to purchase the securities will be subject to certain conditions, and the underwriters will be obligated to purchase all of the securities if they purchase any of them.
If we use a dealer in the sale, we will sell those securities to the dealer as principal. The dealer may then resell the securities to the public at varying prices determined at the time of resale.
Any initial public offering price and any discounts or concessions allowed or reallowed or paid to dealers may be changed from time to time.
Through Agents. We may from time to time designate one or more agents to sell the securities. Unless we state otherwise in the prospectus supplement, any agent will agree to use its best efforts to solicit purchases for the period of its appointment.
Directly. We may sell the securities directly to one or more purchasers. In this case, there will be no underwriters or agents.

| • | the names of any underwriters, dealers or agents, and the amounts of securities underwritten, purchased or sold by each of them, |

Underwriters, agents, dealers and remarketing firms may be entitled under agreements entered into with us to indemnification by us against civil liabilities, including liabilities under the Securities Act of 1933, or to contribution by us with respect to payments which the underwriters or agents may be required to make in respect thereof. Underwriters, agents, dealers and remarketing firms may be customers of, engage in transactions with, or perform services for us and our affiliates in the ordinary course of business.
