Ladies and Gentlemen:

Idaho Power Company, an Idaho corporation (the “Company”), confirms its agreement with each of you with respect to the issue and sale by the Company of up to $200,000,000 aggregate principal amount of its First Mortgage Bonds, Secured Medium-Term Notes, Series F, Due from Nine Months to Thirty Years from Date of Issue (the “Notes”).  The Notes will be issued under the Indenture of Mortgage and Deed of Trust, dated as of October 1, 1937, between the Company and Deutsche Bank Trust Company Americas (formerly known as Bankers Trust Company), (the “Trustee”) and R.G. Page (▇▇▇▇▇▇▇ ▇▇▇▇, successor individual trustee), as trustees, as supplemented and amended by all indentures supplemental thereto including the Fortieth Supplemental Indenture relating to the Notes dated as of May 1, 2005 (the “Supplemental Indenture”).  The Indenture of Mortgage and Deed of Trust as it has been and may be supplemented as of any specified date is hereinafter referred to as the “Indenture”.  Unless otherwise specifically provided for and set forth in a Pricing Supplement (as defined below), the Notes will be issued in minimum denominations of $1,000 and in denominations exceeding such amount by integral multiples of $1,000, will be issued only in fully registered form and will have the interest rates, maturities and, if applicable, other terms set forth in such Pricing Supplement.  The Notes will be issued, and the terms thereof established, in accordance with the Indenture and the Medium-Term Notes Administrative Procedures attached hereto as Exhibit A, as they may be amended from time to time (the “Procedures”) (unless a Terms Agreement (as defined in Section 2(b)) modifies or otherwise supersedes such Procedures with respect to Notes issued pursuant to such Terms Agreement).  The Procedures may be amended only by written agreement of the Company and you after notice to the Trustee.  For the purposes of this Agreement, the term “Agent” shall refer to any of you acting solely in the capacity as agent for the Company pursuant to Section 2(a) and not as principal (collectively, the “Agents”), the term “Purchaser” shall refer to one of you acting solely as principal pursuant to Section 2(b) and not as agent, and the term “you” shall refer to you collectively whether at any time any of you is acting in both such capacities or in either such capacity.  In acting under this Agreement, in whatever capacity, each of you is acting individually and not jointly.

1.             Representations and Warranties.  The Company represents and warrants to, and agrees with, you as set forth below in this Section 1.  Certain terms used in this Section 1 are defined in paragraph (h) hereof.

(a)           The Company meets the requirements for use of Form S-3 under the Securities Act of 1933, as amended (the “Act”) and has filed with the Securities and Exchange Commission (the “Commission”) a registration statement on Form S-3, including a combined prospectus (“Registration Statement No. 333-122153”), for the registration under the Act of $245,000,000 aggregate principal amount of its first mortgage bonds and debt securities (the “Securities”), including the Notes, which registration statement was declared effective by the Commission on January 27, 2005.  The Company also filed with the Commission a registration statement on Form S-3 (“Registration Statement No. 333-103812”) for the registration under the Act of $300,000,000 aggregate principal amount of its first mortgage bonds, serial preferred stock, without par value, and debt securities, of which $245,000,000 principal amount of first mortgage bonds have previously been issued.  Such Registration Statement No. 333-122153, together with the Registration Statement No. 333-103812, as amended as of the date of this Agreement, and the combined prospectus forming a part of the Registration Statement No. 333-

2

122153, as supplemented by a prospectus supplement (the “Prospectus Supplement”) relating to the Notes that the Company has filed or will file with the Commission pursuant to the applicable paragraph of Rule 424(b) under the Act is hereinafter called the “Registration Statement.”  The Registration Statement meets the requirements set forth in Rule 415(a)(1)(ix) or (x) under the Act and complies in all other material respects with said Rule.  In connection with the sale of the Notes the Company proposes to file with the Commission pursuant to the applicable paragraph of Rule 424(b) under the Act further supplements to the Prospectus Supplement (each a “Pricing Supplement”) specifying the interest rates, maturity dates and, if appropriate, other similar terms of the Notes sold pursuant hereto or the offering thereof.

(b)           (i) As of the Execution Time and on the Effective Date, the Registration Statement complied and (ii) on each date any supplement to the Prospectus (as defined herein) relating to the Notes is filed with the Commission, as of the date of a Terms Agreement and at the date of delivery by the Company of any Notes sold hereunder (a “Closing Date”), the Prospectus, as supplemented as of any such time, and the Indenture will comply in all material respects with the applicable requirements of the Act, the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”) and the Securities Exchange Act of 1934, as amended (the “Exchange Act”) and the respective rules thereunder; (iii) as of the Execution Time and on the Effective Date, the Registration Statement, as amended as of either such time, did not contain any untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary in order to make the statements therein not misleading; (iv) on each date any supplement to the Prospectus relating to the Notes is filed with the Commission, as of the date of a Terms Agreement and on any Closing Date, the Prospectus, as supplemented as of any such time, will not contain any untrue statement of a material fact or omit to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; and (v) on any Closing Date no stop order suspending the effectiveness of the Registration Statement shall be in effect nor shall there have been instituted or threatened any proceeding for such purpose; provided, however, that the Company makes no representations or warranties as to (i) that part of the Registration Statement which shall constitute the Statements of Eligibility of the Trustees (Forms T-1 and T-2), or amendments thereto, under the Trust Indenture Act or (ii) the information contained in or omitted from the Registration Statement or the Prospectus (or any supplement thereto) in reliance upon and in conformity with information, if any, furnished in writing to the Company by any of you specifically for inclusion in the Registration Statement or the Prospectus (or any supplement thereto).

(c)           As of the time any Notes are issued and sold hereunder, the Indenture will constitute a legal, valid and binding instrument enforceable against the Company in accordance with its terms and such Notes will have been duly authorized, executed, authenticated and, when paid for by the purchasers thereof, will constitute legal, valid and binding obligations of the Company entitled to the benefits of the Indenture.

(d)           As of the time any Notes are issued and sold, the issue and sale of the Notes and the compliance by the Company with all of the provisions of the Notes, the Indenture, and this Agreement, and the consummation of the transactions herein and therein contemplated will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other

3

agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject, nor will such action result in any violation of the provisions of the Restated Articles of Incorporation, as amended or Bylaws of the Company or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its properties; and no consent, approval, authorization, order, registration or qualification of or with any such court or governmental agency or body is required for the issue and sale of the Notes or the consummation by the Company of the transactions contemplated by this Agreement or the Indenture, except such orders as have been issued by the Idaho Public Utilities Commission (which grants authority to sell the Notes through November 3, 2006), the Public Utility Commission of Oregon and the Public Service Commission of Wyoming and are in full force and effect, and such as have been, or will have been prior to any Closing Date, obtained under the Act and the Trust Indenture Act and such consents, approvals, authorizations, registrations or qualifications as may be required under state securities or Blue Sky laws in connection with the sale and distribution of the Notes by the Agents.

(e)           The Company maintains a system of internal control over financial reporting (as such term is defined in Rule 13a-15(f) of the Exchange Act). The Company’s internal control over financial reporting was effective as of December 31, 2004 and the Company is not aware of any material weaknesses in its internal control over financial reporting.

(f)            Since the date of the latest audited financial statements included or incorporated by reference in the Prospectus, there has been no change in the Company’s internal control over financial reporting that has materially affected, or is reasonably likely to materially affect, the Company’s internal control over financial reporting.

(g)           The Company maintains disclosure controls and procedures (as such term is defined in Rule 13a-15(e) of the Exchange Act) that were effective as of March 31, 2005.

(h)           The terms which follow, when used in this Agreement, shall have the meanings indicated.  The term “Effective Date” shall mean each date that the Registration Statement and any post-effective amendment or amendments thereto became or become effective and each date after the date hereof on which the Company’s most recent Annual Report on Form 10-K is filed.  “Execution Time” shall mean the date and time that this Agreement is executed and delivered by the parties hereto.  “Basic Prospectus” shall mean the form of basic prospectus relating to the Securities contained in the Registration Statement at the Effective Date.  “Prospectus” shall mean the Basic Prospectus as supplemented by the Prospectus Supplement and any applicable Pricing Supplement.  “Registration Statement” shall mean the registration statement referred to in paragraph (a) above, including incorporated documents, exhibits and financial statements, as amended at the Execution Time.  “Rule 415” and “Rule 424” refer to such rules under the Act.  Any reference herein to the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Prospectus shall be deemed to refer to and include the documents incorporated by reference therein pursuant to Item 12 of Form S-3, which were filed under the Exchange Act on or before the Effective Date of the Registration Statement or the issue date of the Basic Prospectus, the Prospectus Supplement or the Prospectus, as the case may be; and any reference herein to the terms “amend”, “amendment” or “supplement” with respect to the Registration Statement, the Basic Prospectus, the Prospectus Supplement or the Prospectus

4

shall be deemed to refer to and include the filing of any document under the Exchange Act after the Effective Date of the Registration Statement or the issue date of the Basic Prospectus, the Prospectus Supplement or the Prospectus, as the case may be, deemed to be incorporated therein by reference; provided, however, that any supplement to the Prospectus filed with the Commission pursuant to Rule 424 under the Act with respect to an offering of First Mortgage Bonds other than the Notes shall not be deemed to be a supplement to, or a part of, the Prospectus.

2.             Appointment of Agents; Solicitation by the Agents of Offers to Purchase; Sales of Notes to a Purchaser.  (a) Subject to the terms and conditions set forth herein and to the reservation by the Company of the right to sell Securities directly on its own behalf, the Company hereby authorizes each of the Agents to act as its agent to solicit offers for the purchase of all or part of the Notes from the Company.

On the basis of the representations and warranties, and subject to the terms and conditions set forth herein, each of the Agents agrees, as agent of the Company, when requested by the Company to use its reasonable best efforts to solicit offers to purchase the Notes from the Company upon the terms and conditions set forth in the Prospectus (and any supplement thereto) and in the Procedures.  Each Agent shall make reasonable efforts to assist the Company in obtaining performance by each purchaser whose offer to purchase Notes has been solicited by such Agent and accepted by the Company, but such Agent shall not, except as otherwise provided in this Agreement, be obligated to disclose the identity of any purchaser or have any liability to the Company in the event any such purchase is not consummated for any reason.  Except as provided in Section 2(b), under no circumstances will any Agent be obligated to purchase any Notes for its own account.  It is understood and agreed, however, that if approved by the Company any Agent may purchase Notes as principal pursuant to Section 2(b).

Each Agent agrees that in carrying out the transactions contemplated by the Agreement, it will observe and comply with all securities or blue sky laws, regulations, rules and ordinances in any jurisdiction in which the Notes may be offered, sold or delivered applicable to it as Agent hereunder.  Each Agent agrees not to cause any advertisement of the Notes to be published in any newspaper or periodical or posted in any public place and not to publicly issue any circular relating to the Notes other than the Prospectus, except in any case with the prior express consent of the Company.

The Company reserves the right, in its sole discretion, to instruct the Agents to suspend at any time, for any period of time or permanently, the solicitation of offers to purchase Notes.  Upon receipt of instructions from the Company, the Agents will forthwith suspend solicitation of offers to purchase Notes from the Company until such time as the Company has advised them that such solicitation may be resumed.

The Company agrees to pay each Agent a commission, for such Agent’s services in acting as an agent and not for a purchase by such Agent as principal, on the Closing Date with respect to each sale of Notes by the Company as a result of a solicitation made by such Agent, in an amount equal to that percentage specified in Schedule I hereto of the aggregate principal amount of the Notes sold by the Company.  Such commission shall be payable as specified in the Procedures.

5

The Company may from time to time offer Securities or Notes for sale otherwise than through an Agent and from time to time may appoint additional agents to sell the Notes; provided, however, that so long as this Agreement shall be in effect, the Company shall not solicit or accept offers to purchase Notes through any agent other than an Agent, except that the Company may accept offers to purchase Notes through an agent other than an Agent if the Company gives the Agents reasonable prior notice of such acceptance and any such agent enters into an agreement with the Company on terms which are substantially similar to those contained in or incorporated in this Agreement.

If the Company shall default in its obligations to deliver Notes to a purchaser whose offer it has accepted, the Company shall indemnify and hold each of you harmless against any loss, claim or damage arising from or as a result of such default by the Company.

(b)           Subject to the terms and conditions stated herein, whenever the Company and any of you determine that the Company shall sell Notes directly to any of you as principal, each such sale of Notes shall be made in accordance with the terms of this Agreement and a supplemental agreement relating to such sale.  Each such supplemental agreement is herein referred to as a “Terms Agreement”.  Each Terms Agreement shall describe the Notes to be purchased by the Purchaser pursuant thereto and shall specify the aggregate principal amount of such Notes, the price to be paid to the Company for such Notes, the maturity date of such Notes, the rate at which interest will be paid on such Notes, the dates on which interest will be paid on such Notes and the record date with respect to each such payment of interest, the Closing Date for the purchase of such Notes, the place of delivery of the Notes and payment therefor, the method of payment and any requirements for the delivery of opinions of counsel, certificates from the Company or its officers or a letter from the Company’s independent registered public accounting firm as described in Section 6(b).  Any such Terms Agreement may also specify the period of time referred to in Section 4(1) and certain terms of the reoffering of the Notes.  Any Terms Agreement shall be substantially in the form attached hereto as Exhibit B and may take the form of an exchange of any standard form of written telecommunication between the Purchaser and the Company.  The Purchaser’s commitment to purchase Notes shall be deemed to have been made on the basis of the representations and warranties of the Company herein contained and shall be subject to the terms and conditions herein set forth.

Delivery of the certificates for Notes sold to the Purchaser pursuant to a Terms Agreement shall be made not later than the Closing Date agreed to in such Terms Agreement, against payment of funds to the Company in the net amount due to the Company for such Notes by the method and in the form set forth in the Procedures unless otherwise agreed to between the Company and the Purchaser in such Terms Agreement.

Unless otherwise agreed to between the Company and the Purchaser in a Terms Agreement, any Note sold to a Purchaser (i) shall be purchased by such Purchaser at a price equal to 100% of the principal amount thereof less a percentage equal to the commission applicable to an agency sale of a Note of identical maturity and (ii) may be resold by such Purchaser at varying prices related to prevailing market prices determined at the time of resale or, if set forth in the applicable Terms Agreement and Pricing Supplement, at a fixed public offering price.  In connection with any resale of Notes purchased, a Purchaser may use a selling or dealer group and may reallow to any broker or dealer any portion of the discount or

6

commission payable pursuant hereto.  Any resale at a discount may not exceed the amount set forth in the Pricing Supplement relating to such Notes.

3.             Offering and Sale of Notes.  Each Agent and the Company agree to perform the respective duties and obligations specifically provided to be performed by them in the Procedures.

4.             Agreements.  The Company agrees with you that:

(a)           Prior to the termination of the offering of the Notes (including by way of resale by a Purchaser of Notes), the Company will not file any amendment to the Registration Statement or supplement to the Prospectus (except for (i) periodic or current reports filed under the Exchange Act, (ii) a supplement relating to any offering of Notes providing solely for the specification of or a change in the maturity dates, interest rates, issuance prices or other similar terms of any Notes or (iii) an amendment or a supplement relating to an offering of Securities other than the Notes) unless the Company has furnished each of you through your counsel a copy for your review prior to filing and given each of you a reasonable opportunity to comment on any such proposed amendment or supplement.  Subject to the foregoing sentence, the Company will cause each supplement to the Prospectus to be filed with the Commission pursuant to the applicable paragraph of Rule 424(b) within the time period prescribed and will provide evidence satisfactory to you of such filing.  The Company will promptly advise each of you (i) when the Prospectus, and any supplement thereto, shall have been filed with the Commission pursuant to Rule 424(b), (ii) when, prior to termination of any offering of Notes, any amendment of the Registration Statement (except periodic or current reports filed under the Exchange Act) shall have been filed or become effective, (iii) of any request by the Commission for any amendment of the Registration Statement or supplement to the Prospectus or for any additional information, (iv) of the issuance by the Commission of any stop order suspending the effectiveness of the Registration Statement or the institution or threatening of any proceeding for that purpose and (v) of the receipt by the Company of any notification with respect to the suspension of the qualification of the Notes for sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose.  The Company will use its best efforts to prevent the issuance of any such stop order and, if issued, to obtain as soon as possible the withdrawal thereof.

(b)           If, at any time when a prospectus relating to the Notes is required to be delivered under the Act, any event occurs as a result of which the Prospectus as then supplemented would include any untrue statement of a material fact or omit to state any material fact necessary to make the statements therein, in the light of the circumstances under which they were made, not misleading, or if it shall be necessary to amend the Registration Statement or to supplement the Prospectus to comply with the Act or the Exchange Act or the respective rules thereunder, the Company promptly will (i) notify each of you to suspend solicitation of offers to purchase Notes (and, if so notified by the Company, each of you shall forthwith suspend such solicitation and cease using the Prospectus as then supplemented), (ii) prepare and file with the Commission, subject to the first sentence of paragraph (a) of this Section 4, an amendment or supplement which will correct such statement or omission or effect such compliance and (iii) supply any supplemented Prospectus to each of you in such quantities as you may reasonably request.  If such amendment or supplement is satisfactory in all respects to you, you will, upon the filing of such amendment or supplement with the Commission and upon the effectiveness of

7

an amendment to the Registration Statement, if such an amendment is required, resume your obligation to solicit offers to purchase Notes hereunder.

(c)           The Company, during the period when a prospectus relating to the Notes is required to be delivered under the Act, will file promptly all documents required to be filed with the Commission pursuant to Section 13(a), 13(c), 14 or 15(d) of the Exchange Act and will furnish to each of you copies of such documents.

(d)           As soon as practicable, the Company will make generally available to its security holders and to each of you an earnings statement or statements of the Company and its subsidiaries which will satisfy the provisions of Section 11(a) of the Act and Rule 158 under the Act.

(e)           The Company will furnish to each of you and your counsel, without charge, copies of the Registration Statement (including exhibits thereto), each amendment or supplement to the Indenture entered into subsequent to the date hereof, and, so long as delivery of a prospectus may be required by the Act, as many copies of the Prospectus and any supplement thereto as you may reasonably request.

(f)            The Company will use its best efforts to arrange for the qualification of the Notes for sale under the laws of such jurisdictions as any of you may reasonably designate, and will maintain such qualifications in effect so long as required for the distribution of the Notes, except that the Company shall not be required to qualify as a foreign corporation or dealer in securities or to execute a general consent to service of process in any jurisdiction.

(g)           The Company shall, whether or not any sale of the Notes is consummated, (i) pay all expenses incident to the performance of its obligations under this Agreement and any Terms Agreement, including the fees and disbursements of its accountants and counsel, the cost of printing or other production and delivery of the Registration Statement, the Prospectus, all amendments thereof and supplements thereto, the Supplemental Indenture, this Agreement, any Terms Agreement and all other documents relating to the offering, the cost of preparing, printing, packaging and delivering the Notes, the fees and disbursements of your counsel incurred in compliance with Section 4(f) (such fees not to exceed $10,000), the fees and disbursements of the Trustee and the fees of any agency that rates the Notes, (ii) reimburse each of you as requested for all out-of-pocket expenses (including pre-approved advertising expenses), if any, incurred by you in connection with the implementation of this program and (iii) pay the reasonable fees and expenses of your counsel incurred in connection with the implementation of this program.

(h)           Each acceptance by the Company of an offer to purchase Notes will be deemed to be an affirmation that its representations and warranties contained in this Agreement are true and correct at the time of such acceptance, as though made at and as of such time, and a covenant that such representations and warranties will be true and correct at the Closing Date relating to such acceptance, as though made at and as of such time (it being understood that for purposes of the foregoing affirmation and covenant such representations and warranties shall relate to the Registration Statement and Prospectus as amended or supplemented at each such time).  Each such acceptance by the Company of an offer for the purchase of Notes shall be

8

deemed to constitute an additional representation, warranty and agreement by the Company that, as of the Closing Date for the sale of such Notes, after giving effect to the issuance of such Notes, of any other Notes to be issued on or prior to such Closing Date and of any other Securities to be issued and sold by the Company on or prior to such Closing Date, the aggregate amount of Securities (including any Notes) which have been issued and sold by the Company will not exceed the amount of Securities registered pursuant to the Registration Statement.  The Company will inform you promptly upon your request of the aggregate amount of Securities registered under the Registration Statement which remain unsold.

(i)            Each time the Company files with the Commission an Annual Report on Form 10-K or a Quarterly Report on Form 10-Q or a material amendment or supplement thereto, each time that the Company requests you to solicit offers to purchase the Notes and each time that a Terms Agreement is executed and delivered, the Company will deliver or cause to be delivered promptly to you a certificate of the Company, in form reasonably satisfactory to you, signed by the Chief Executive Officer or the President or the principal financial or accounting officer of the Company, dated the date of delivery of such certificate, of the same tenor as the certificate referred to in Section 5(d) but modified to relate to the Registration Statement and the Prospectus as amended or supplemented at the time of delivery of such certificate.

(j)            Each time the Company files with the Commission an Annual Report on Form 10-K or a Quarterly Report on Form 10-Q or a material amendment or supplement thereto, each time that the Company requests you to solicit offers to purchase the Notes and each time that a Terms Agreement is executed and delivered, the Company will furnish or cause to be furnished promptly to you a written opinion of counsel for the Company, in form reasonably satisfactory to you, dated the date of delivery of such opinion, of the same tenor as the opinion referred to in Section 5(b) but modified to relate to the Registration Statement and the Prospectus as amended or supplemented at the time of delivery of such opinion or, in lieu of such opinion, counsel last furnishing such an opinion to you may furnish you with a letter to the effect that you may rely on such last opinion to the same extent as though it were dated the date of such letter authorizing reliance (except that statements in such last opinion will be deemed to relate to the Registration Statement and the Prospectus as amended and supplemented to the time of the effectiveness of such amendment or the filing of such supplement).

(k)           Each time the Company files with the Commission an Annual Report on Form 10-K or a Quarterly Report on Form 10-Q or a material amendment or supplement thereto, each time that the Company requests you to solicit offers to purchase the Notes and each time that a Terms Agreement is executed and delivered, the Company will cause its independent registered public accounting firm promptly to furnish you a letter, dated five business days after the date of the effectiveness of such amendment or the date of filing of such supplement, in form reasonably satisfactory to you, of the same tenor as the letter referred to in Section 5(e) with such changes as may be necessary to reflect the amended and supplemental financial information included or incorporated by reference in the Registration Statement and the Prospectus, as amended or supplemented to the date of such letter; provided, however, that, if the Registration Statement or the Prospectus is amended or supplemented solely to include or incorporate by reference financial information as of and for a fiscal quarter, the Company’s independent registered public accounting firm may limit the scope of such letter, which shall be satisfactory

9

in form to you, to the unaudited financial statements, the related “Management’s Discussion and Analysis of Financial Condition and Results of Operations” and any other information of an accounting, financial or statistical nature included in such amendment or supplement, unless, in your reasonable judgment, such letter should cover other information or changes in specified financial statement line items.

(l)            During the period, if any, specified in any Terms Agreement, the Company shall not, without the prior consent of the Purchaser thereunder, offer, sell or contract to sell, or otherwise dispose of, directly or indirectly, or announce the offering of, any first mortgage bonds issued by the Company (other than the Notes being sold pursuant to such Terms Agreement).

(m)          Notwithstanding the foregoing, it is agreed that if, at any time and from time to time during the term of this Agreement, the Company should deliver to the Agents notification of its decision to suspend any sale of Notes hereunder, then during the period of any such suspension or suspensions the Company shall be relieved of its obligation to provide to the Agents the certificate, opinions and letter required pursuant to Sections 4(i), 4(j) and 4(k) hereof.  However, whenever such a suspension is lifted, the Company shall be required to deliver to the Agents, prior to the resumption of any sale of Notes hereunder, the most recent certificate, opinions and letter which would have been required except for the suspension.

(n)           During the term of this Agreement, the Company shall furnish to each Agent (i) copies of all annual, quarterly and current reports (without exhibits but including documents incorporated therein by reference) of the Company filed with the Commission under the Exchange Act, (ii) copies of all announcements made to the general financial community and (iii) notice of (x) any decrease in the rating or (y) credit watch with negative implications, in either case of the Notes or any other debt securities of the Company, by any “nationally recognized statistical rating organization” (as defined for purposes of Rule 436(g) under the Act).

(o)           The Company agrees that any person who has agreed to purchase and pay for any Note pursuant to a solicitation by any of the Agents shall have the right to refuse to purchase such Note if, subsequent to the agreement to purchase such Note, any change, condition or development specified in any of Sections 8(b)(iii), (iv) or (v) shall have occurred (with the judgment of the Agent which presented the offer to purchase such Note being substituted for any judgment of a Purchaser required therein) the effect of which is, in the judgment of the Agent which presented the offer to purchase such Note, so material and adverse as to make it impractical or inadvisable to proceed with the sale and delivery of such Note (it being understood that under no circumstance shall any such Agent have any duty or obligation to the Company or to any such person to exercise the judgment permitted to be exercised under this Section 4(o)).

5.             Conditions to the Obligations of the Agents.  The obligations of each Agent to solicit offers to purchase the Notes shall be subject to the accuracy of the representations and warranties on the part of the Company contained herein as of the Execution Time, on the Effective Date, when any supplement to the Prospectus relating to the Notes is filed with the Commission and as of each Closing Date, to the accuracy of the statements of the Company

10

made in any certificates pursuant to the provisions hereof, to the performance by the Company of its obligations hereunder and to the following additional conditions:

(a)           If filing of the Prospectus, or any supplement thereto, is required pursuant to Rule 424(b), the Prospectus, and any such supplement, shall have been filed in the manner and within the time period required by Rule 424(b); and no stop order suspending the effectiveness of the Registration Statement shall have been issued and no proceedings for that purpose shall have been instituted or threatened.

(b)           The Company shall have furnished to each Agent the opinions of ▇▇▇▇▇▇▇, ▇▇▇▇, ▇▇▇▇▇▇ & ▇▇▇▇▇▇, L.L.P., counsel to the Company and ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇, Esq., General Counsel for the Company, dated the Execution Time substantially in the forms of Exhibits D and E hereto.

(c)           Each Agent shall have received from ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP, counsel for the Agents, such opinion or opinions, dated the Execution Time, with respect to the incorporation of the Company, the validity of the Indenture and the Notes, the Registration Statement, the Prospectus (together with any supplement thereto) and other related matters as the Agents may reasonably require, and the Company shall have furnished to such counsel such documents as they may reasonably request for the purpose of enabling them to pass upon such matters.  In rendering their opinions, ▇▇▇▇▇▇▇▇ & ▇▇▇▇▇▇▇▇ LLP may rely upon the opinion described above of ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇, Esq., General Counsel for the Company, as to all matters of Idaho, Montana, Nevada, Oregon and Wyoming law.

7.             Indemnification.  (a) The Company will indemnify and hold harmless each of you against any losses, claims, damages or liabilities, joint or several, to which you may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any preliminary prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus, or any amendment or supplement thereto, and any other prospectus relating to the Notes, or arise out of or are based upon the omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading; and will reimburse each of you for any legal or other expenses reasonably incurred by you in connection with investigating or defending against such loss, claim, damage, liability or action as such expenses are incurred; provided, however, that the Company shall not be liable in any such case to the extent that any such loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission made in any preliminary prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus, or such amendment or supplement and any other prospectus relating to the Notes, in reliance upon and in conformity with information furnished in writing to the Company by you or on your behalf for inclusion therein or arising out of, or based upon, statements in or omissions from Exhibits 25.1 and 25.3 to the Registration Statement which shall constitute the Statements of Eligibility of the Trustees on Forms T-1 and T-2, or amendments thereto, under the Indenture and provided further that the Company shall not be liable to any of you under the indemnity agreement in this subsection on account of any such loss, claim, damage or liability of yours arising from the sale of the Notes to any person, if at or prior to the written confirmation of such sale a copy of the Prospectus (exclusive of the documents incorporated by reference therein), or of the Prospectus as then amended or supplemented (exclusive of the documents incorporated by reference therein) shall not have been given or sent to such person by you or on your behalf.  This indemnity agreement shall be in addition to any liability which the Company may otherwise have.

The foregoing indemnity agreement shall, upon the same terms and conditions, extend to and inure to the benefit of each person, if any, who controls any of you within the meaning of the Act.

(b)           Each of you severally and not jointly will indemnify and hold harmless the Company against any losses, claims, damages or liabilities to which the Company may become subject, under the Act or otherwise, insofar as such losses, claims, damages or liabilities (or actions in respect thereof) arise out of or are based upon any untrue statement or alleged untrue statement of any material fact contained in any preliminary prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus, or any amendment or supplement thereto, and any other prospectus relating to the Notes, or arise out of or are based

13

upon the omission or the alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, in each case to the extent, but only to the extent, that such untrue statement or alleged untrue statement or omission or alleged omission was made in a preliminary prospectus, any preliminary prospectus supplement, the Registration Statement, the Prospectus, or such amendment or supplement, and any other Prospectus relating to the Notes, in reliance upon and in conformity with information furnished in writing to the Company by you or on your behalf for inclusion therein; and will reimburse the Company for any legal or other expenses reasonably incurred by the Company in connection with investigating or defending against any such loss, claim, damage, liability or action as such expenses are incurred.  This indemnity agreement shall be in addition to any liability which you may otherwise have.

The foregoing indemnity agreement shall, upon the same terms and conditions, extend to and inure to the benefit of each director of the Company, each of its officers who has signed the Registration Statement and each person, if any, who controls the Company within the meaning of the Act.

(c)           Promptly after receipt by an indemnified party under subsection (a) or (b) above of notice of the commencement of any action, such indemnified party shall, if a claim in respect thereof is to be made against the indemnifying party under such subsection, notify the indemnifying party in writing of the commencement thereof; but the omission so to notify the indemnifying party shall not relieve it from any liability which it may have to any indemnified party otherwise than under such subsection.  In case any such action shall be brought against any indemnified party, and it shall notify the indemnifying party of the commencement thereof, the indemnifying party shall be entitled to participate in, and, to the extent that it shall wish, jointly with any other indemnifying party similarly notified, to assume the defense thereof, with counsel satisfactory to such indemnified party (who shall not, except with the consent of the indemnified party, be counsel to the indemnifying party), and after notice from the indemnifying party to such indemnified party of its election so to assume the defense thereof, the indemnifying party shall not be liable to such indemnified party under such subsection for any legal or other expenses subsequently incurred by such indemnified party in connection with the defense thereof other than reasonable costs of investigation.

(d)           If the indemnification provided for in this Section 7 is unavailable to or insufficient to hold harmless an indemnified party under subsection (a) or (b) above in respect of any losses, claims, damages or liabilities (or actions in respect thereof) referred to therein, then each indemnifying party shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (or actions in respect thereof) in such proportion as is appropriate to reflect the relative benefits received by the Company on the one hand and each of you on the other from the offering of the Notes to which such loss, claim, damage or liability (or actions in respect thereof) relates and also the relative fault of the Company on the one hand and each of you on the other in connection with the statements or omissions which resulted in such losses, claims, damages or liabilities (or actions in respect thereof), as well as any other relevant equitable considerations.  The relative benefits received by the Company on the one hand and each of you on the other shall be deemed to be in the same proportion as the total net proceeds from such offering (before deducting expenses) received by the Company bear to the total discounts and commissions received by you.  The relative fault

14

shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Company on the one hand or any of you on the other and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission.  The Company and each of you agree that it would not be just and equitable if contribution pursuant to this subsection (d) were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to above in this subsection (d).  The amount paid or payable by an indemnified party as a result of the losses, claims, damages or liabilities (or actions in respect thereof) referred to above in this subsection (d) shall be deemed to include any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim.  Notwithstanding the provisions of this subsection (d), you shall not be required to contribute any amount in excess of the amount by which the total price at which the Notes sold by or through you to the public exceeds the amount of any damages which you have otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission.  No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation.  The obligations of each of you in this subsection (d) to contribute are several in proportion to the respective purchases made by or through you to which such loss, claim, damage or liability (or action in respect thereof) relates and are not joint.

8.             Termination.  (a)  This Agreement will continue in effect until terminated as provided in this Section 8.  This Agreement may be terminated either by the Company as to any Agent or by any of you insofar as this Agreement relates to any Agent, by giving written notice of such termination to such Agent or the Company, as the case may be.  This Agreement shall so terminate at the close of business on the first business day following the receipt of such notice by the party to whom such notice is given.  In the event of such termination, no party shall have any liability to the other party hereto, except as provided in the fifth paragraph of Section 2(a), Section 4(g), Section 7 and Section 9.

(b)           Each Terms Agreement shall be subject to termination in the absolute discretion of the Purchaser, by written notice given to the Company prior to delivery of any payment for any Note to be purchased thereunder, if subsequent to the agreement to purchase such Note and prior to such payment time (i) there shall have occurred any change in or affecting the business or properties of the Company and its subsidiaries taken as a whole the effect of which is, in the judgment of the Purchaser, so material and adverse as to make it impracticable or inadvisable to enforce contracts for the sale of such Note, (ii) there shall have been any decrease in the rating of any of the Company’s first mortgage bonds by ▇▇▇▇▇’▇ Investors Service or Standard & Poor’s Ratings Services the effect of which is, in the judgment of the Purchaser, so material and adverse as to make it impracticable or inadvisable to enforce contracts for the sale of such Note, (iii) trading in securities generally on the New York Stock Exchange shall have been suspended or limited or minimum prices shall have been established on such Exchange, (iv) a general moratorium on commercial banking activities shall have been declared by either Federal or New York State authorities or a material disruption in commercial banking or securities settlement or clearance services in the United States shall have occurred, (v) there shall have occurred any outbreak or escalation of hostilities, declaration by the United States of a national emergency or war or other calamity or crisis the effect of which is such as to make it, in

15

the judgment of the Purchaser, impracticable or inadvisable to proceed with the public offering or the delivery of the Notes on the terms and in the manner contemplated in the Prospectus or (vi) there shall have occurred any adverse change in national or international financial, political or economic conditions the effect of which is such as to make it, in the judgment of the Purchaser, impracticable or inadvisable to proceed with the public offering or the delivery of the Notes on the terms and in the manner contemplated in the Prospectus.

9.             Survival of Certain Provisions.  The respective representations, warranties, indemnities and other statements of the Company or its officers and of you set forth in or made pursuant to this Agreement will remain in full force and effect, regardless of any investigation made by or on behalf of you or the Company or any of the persons referred to in Section 7 hereof, and will survive delivery of and payment for the Notes.  The provisions of Sections 4(g) and 7 hereof shall survive the termination or cancellation of this Agreement.  The provisions of this Agreement applicable to any purchase of a Note for which an agreement to purchase exists prior to the termination hereof shall survive any termination of this Agreement.  If at the time of termination of this Agreement any Purchaser shall own any Notes with the intention of selling them, the provisions of Section 4 shall remain in effect until such Notes are sold by the Purchaser.

10.           Notices.  All communications hereunder will be in writing and effective only on receipt, and, if sent to any of you, will be mailed, delivered or telegraphed and confirmed to such of you, at the address specified in Schedule I hereto; or, if sent to the Company, will be mailed, delivered or telegraphed and confirmed to it at ▇▇▇▇ ▇. ▇▇▇▇▇ ▇▇▇▇▇▇, ▇▇▇▇▇, ▇▇▇▇▇ ▇▇▇▇▇-▇▇▇▇, attention of the Secretary.

11.           Successors.  This Agreement will inure to the benefit of and be binding upon the parties hereto, their respective successors, the controlling persons referred to in Section 7 hereof and no other person will have any right or obligation hereunder.

12.           Applicable Law.  This Agreement will be governed by and construed in accordance with the laws of the State of New York.

13.           Counterparts.  This Agreement may be executed by any one or more of the parties hereto and thereto in any number of counterparts, each of which shall be deemed to be an original, but all such respective counterparts shall together constitute one and the same instrument.

16

If the foregoing is in accordance with your understanding of our agreement, please sign and return to us the enclosed duplicate hereof, whereupon this letter and your acceptance shall represent a binding agreement among the Company and you.

hereby confirmed and accepted

(ii)           In their opinion, the consolidated financial statements and consolidated financial statement schedules audited by them and included or incorporated by reference in the Registration Statement or the Prospectus comply as to form in all material respects with the applicable accounting requirements of the Act or the Exchange Act, as applicable, and the related rules and regulations adopted by the SEC, and, if applicable, they have performed the procedures specified by the American Institute of Certified Public Accountants for a review of interim financial information as described in SAS No. 71, Interim Financial Information, on the consolidated interim financial statements for the periods specified in such letter, as indicated in their reports thereon, copies of which have been furnished to the Agents;

(iii)          On the basis of limited procedures, not constituting an audit in accordance with generally accepted auditing standards, consisting of a reading of the unaudited financial statements and other information referred to below, a reading of the latest available interim financial statements of the Company and its subsidiaries, inspection of the minute books of the Company and its subsidiaries since the date of the latest audited financial statements included or incorporated by reference in the Prospectus, inquiries of officials of the Company and its subsidiaries responsible for financial and accounting matters and such other inquiries and procedures as may be specified in such letter, nothing has come to their attention that caused them to believe that:

(A)          the unaudited consolidated statements of income, consolidated statements of comprehensive income, consolidated balance sheets, consolidated statements of cash flows and consolidated statements of capitalization included or incorporated by reference in the Company’s Quarterly Reports on Form 10-Q incorporated by reference in the Prospectus do not comply as to form in all material respects with the applicable accounting requirements of the Exchange Act as it applies to Form 10-Q and the related rules and regulations adopted by the SEC;

increases or decreases which the Prospectus discloses have occurred or may occur, for declarations of dividends, or which are described in such letter; and

(D)          for the period from the date of the latest financial statements included or incorporated by reference in the Prospectus to the specified date referred to in Clause (C) there were any decreases in consolidated revenues, net income or earnings on common stock or other items specified by the Agents, or any increases in any items specified by the Agents, in each case as compared with the comparable period of the preceding year and with any other period of corresponding length specified by the Agents, except in each case for increases or decreases which the Prospectus discloses have occurred or may occur, for declarations of dividends, or which are described in such letter; and

(iv)          In addition to the audit referred to in their report(s) included or incorporated by reference in the Prospectus and the limited procedures, inspection of minute books, inquiries and other procedures referred to in paragraphs (ii) and (iii) above, they have carried out certain specified procedures, not constituting an audit in accordance with generally accepted auditing standards, with respect to certain amounts, percentages and financial information specified by the Agents which are derived from the general accounting records of the Company and its subsidiaries, which appear in the Prospectus (excluding documents incorporated by reference), or in Part II of, or in exhibits and schedules to, the Registration Statement specified by the Agents or in documents incorporated by reference in the Prospectus specified by the Agents, and have compared certain of such amounts, percentages and financial information with the accounting records of the Company and its subsidiaries and have found them to be in agreement, except as described in such letter.

All references in this Exhibit C to the Prospectus shall be deemed to refer to the Prospectus (including the documents incorporated by reference therein) as amended or supplemented (including the documents incorporated by reference therein) in relation to the Notes for purposes of the letter delivered at the Closing Date for such Notes.

Page, as Trustees (▇▇▇▇▇▇▇ ▇▇▇▇, successor individual trustee) (the “Trustees”), as supplemented by all indentures supplemental thereto, the latest such supplemental indenture being the Fortieth Supplemental Indenture, dated as of May 1, 2005 (said Indenture of Mortgage and Deed of Trust, as so supplemented, being hereinafter called the “Mortgage”), we advise you that we are counsel to the Company and in that capacity have reviewed or participated in the preparation of (1) the Mortgage; (2) the registration statement (File No. 333-103812) filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”), which became effective on March 24, 2003 (“Registration Statement No. 333-103812”) and the registration statement (File No. 333-122153) filed with the Securities and Exchange Commission under the Act, which became effective on January 27, 2005 (“Registration Statement No. 333-122153”; Registration Statement No. 333-122153 and Registration Statement No. 333-103812, as amended to their respective dates of effectiveness, including the documents incorporated by reference therein as of such dates pursuant to Item 12 of Form S-3 (the “Incorporated Documents”), being hereinafter referred to collectively as the “Registration Statement”); (3) the combined prospectus, dated January 27, 2005 (the “Base Prospectus”), as supplemented by a prospectus supplement relating to the Notes, dated May 9, 2005 (the “Prospectus Supplement”) (such prospectus, as so supplemented, including the Incorporated Documents, being hereinafter referred to as the “Prospectus”); (4) the Agency Agreement and (5) the Bond Application, dated May 9, 2005 for authentication and delivery of the Notes in an aggregate principal amount not to exceed $200,000,000 (the “Bond Application”).  Terms not otherwise defined herein shall have the meanings given to them in the Agency Agreement.

We have also reviewed such corporate records, certificates and other documents as we have considered necessary or appropriate for purposes of this opinion.

Based upon and subject to the foregoing, we are of the opinion that:

(1)           The Mortgage has been duly authorized, executed and delivered by the Company, is a legal, valid and binding instrument enforceable in accordance with its terms, subject to bankruptcy, insolvency, reorganization or other laws of general applicability relating to or affecting mortgagees’ and other creditors’ rights, and to general principles of equity (whether considered in a proceeding at law or in equity) and has been qualified under the Trust Indenture Act of 1939, as amended.

(2)           The Notes, when issued and paid for as contemplated in the Agency Agreement, will be legal, valid and binding obligations of the Company enforceable in accordance with their terms and entitled to the benefit of the security provided by the Mortgage, subject to bankruptcy, insolvency, reorganization or other laws of general applicability relating to or affecting mortgagees’ and other creditors’ rights and to general principles of equity (whether considered in a proceeding at law or in equity).

(3)           The Agency Agreement has been duly authorized, executed and delivered by the Company.

(4)           As of their respective effective dates, Registration Statement No. 333-103812 and Registration Statement No. 333-122153, including the Incorporated Documents, and, as of the date of the Prospectus Supplement, the Base Prospectus, as supplemented by the Prospectus Supplement, appeared on their face to comply as to form in all material respects with the applicable requirements of the Act and the Securities Exchange Act of 1934, as amended, and the applicable instructions, rules and regulations of the Commission thereunder; the Registration Statement is effective under the Act; and, to our knowledge, no proceedings for a stop order with respect thereto are pending or threatened under Section 8(d) of the Act.

(5)           All regulatory consents and approvals required to be obtained by the Company from any governmental body or bodies in connection with the Company’s issuance and sale of the Notes in the manner set forth in the Agency Agreement have been obtained and are in effect, except that the order of the Idaho Public Utilities Commission grants authority to sell the Notes only through November 3, 2006; it being understood that we express no opinion as to any consents or approvals required to be obtained, or other actions required to be taken, under the securities or blue sky laws of any jurisdiction.

In passing upon the form of the Registration Statement and the form of the Base Prospectus, as supplemented by the Prospectus Supplement, we necessarily assume the correctness and completeness of the representations made to us and the statements made to us or included in the Registration Statement and the Base Prospectus, as supplemented by the Prospectus Supplement, by the Company and take no responsibility therefor.  In the course of the preparation by the Company of the Registration Statement and the Base Prospectus, we had conferences with certain of its officers and representatives, with other counsel for the Company and with Deloitte & Touche LLP, the independent registered public accounting firm who examined certain of the financial statements included or incorporated by reference in the Registration Statement.  In the course of our examination of the Registration Statement and the Base Prospectus, as supplemented by the Prospectus Supplement, and our discussions in the above-mentioned conferences, nothing caused us to believe that, at their respective effective dates, Registration Statement No. 333-103812 or Registration Statement No. 333-122153,

including the Incorporated Documents, contained any untrue statements of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that, as of the date of the Prospectus Supplement, the Base Prospectus, as supplemented by the Prospectus Supplement, contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.  Also, nothing has come to our attention in the course of our examination of the Registration Statement or the Prospectus or in our discussions in the above-mentioned conferences that has caused us to believe that the Prospectus, as of the date and time of the delivery of this letter, contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.  We express no view as to the financial statements or other financial or accounting data contained or incorporated by reference in the Registration Statement or the Prospectus.

We express no opinion as to the law of any jurisdiction other than the law of the State of New York and the federal laws of the United States.  As to all matters of Idaho law and as to the matters set forth in paragraph 5 above, we have relied upon an opinion of even date herewith addressed to you by ▇▇▇▇▇▇ ▇. ▇▇▇▇▇▇, Esq., General Counsel for the Company.  We are not passing upon matters relating to the incorporation of the Company, title to property, liens, licenses, franchises, water rights or conformity to the laws of the States of Idaho, Montana, Nevada, Oregon or Wyoming, or upon questions of the recording of, or the validity or priority of the lien of, the Mortgage.

Very truly yours,

To the Agents referred to in the
Selling Agency Agreement
Relating to:

$200,000,000 Principal Amount of
First Mortgage Bonds, Secured Medium-
Term Notes, Series F, of Idaho Power Company

Ladies and Gentlemen:

In connection with the issuance and sale pursuant to the Selling Agency Agreement, dated May 9, 2005 (the “Agency Agreement”), between Idaho Power Company, an Idaho corporation (the “Company”), and you of up to $200,000,000 aggregate principal amount of the Company’s First Mortgage Bonds, Secured Medium-Term Notes, Series F (the “Notes”), to be issued under an Indenture of Mortgage and Deed of Trust, dated as of October 1, 1937, between the Company and Deutsche Bank Trust Company Americas (formerly known as Bankers Trust Company) and R.G. Page, as Trustees (▇▇▇▇▇▇▇ ▇▇▇▇, successor individual trustee) (the “Trustees”), as supplemented by all indentures supplemental thereto, the latest such supplemental indenture being the Fortieth Supplemental Indenture, dated as of May 1, 2005 between the Company and the Trustees (collectively, the “Mortgage”), I am the Company’s General Counsel, and I am familiar with its legal status and that of its property.  I am also familiar with (a) the registration statement (File No. 333-103812) filed with the Securities and Exchange Commission under the Securities Act of 1933, as amended (the “Act”), which became effective on March 24, 2003 (“Registration Statement No. 333-103812”) and the registration statement (File No. 333-122153) filed with the Securities and Exchange Commission under the Act, which became effective on January 27, 2005 (“Registration Statement No. 333-122153”; Registration Statement No. 333-122153 and Registration Statement No. 333-103812, as amended to their respective dates of effectiveness, including the documents incorporated by reference therein as of such dates pursuant to Item 12 of Form S-3 (the “Incorporated Documents”), being hereinafter referred to collectively as the “Registration Statement”), (b) the combined prospectus, dated January 27, 2005 (the “Base Prospectus”), as supplemented by a prospectus supplement relating to the Notes, dated May 9, 2005 (the “Prospectus Supplement”) (such prospectus, as so supplemented, including the Incorporated Documents, being hereinafter referred to as the “Prospectus”), (c) the Agency Agreement and (d) the Bond Application, dated May 9, 2005 for authentication and delivery of the Notes in an aggregate principal amount not to exceed $200,000,000 (the “Bond Application”).  Terms not otherwise defined herein shall have the meanings given to them in the Agency Agreement.

I have made such examination of corporate and other records and documents and of matters of law as in my opinion are necessary or desirable for the purposes of this opinion, and based ▇▇▇▇▇▇▇, I am of the opinion that:

(1)           The Company has been duly incorporated and is validly existing and in good standing under the laws of the State of Idaho, and has full power and authority to own its properties and conduct its business in all material respects as described in the Prospectus as amended or supplemented;

(2)           To the best of my knowledge and other than as set forth in the Prospectus as amended or supplemented, there are no legal or governmental proceedings pending to which the Company or any of its subsidiaries is a party or of which any property of the Company or any of its subsidiaries is the subject which would individually or in the aggregate have a material adverse effect on the consolidated financial position or results of operations of the Company and its subsidiaries considered as a whole; and, to the best of my knowledge, no such proceedings are threatened or contemplated by governmental authorities or threatened by others;

(3)           The Agency Agreement has been duly authorized, executed and delivered by the Company;

(4)           The Notes, when issued and paid for as contemplated in the Agency Agreement, will be legal, valid and binding obligations of the Company, enforceable in accordance with their terms and entitled to the benefit of the security provided by the Mortgage, subject to bankruptcy, insolvency, reorganization or other laws of general applicability relating to or affecting mortgagees’ and other creditors’ rights and to general principles of equity (whether considered in a proceeding at law or in equity); and the Notes and the Mortgage conform to the descriptions thereof in the Prospectus as amended or supplemented;

(5)           The Mortgage has been duly authorized, executed and delivered by the Company and constitutes a valid lien to the extent that it purports to be one upon the property described therein as being subject to the lien thereof (except any which has been duly released from the lien thereof) and is a legal, valid and binding instrument, enforceable in accordance with its terms, subject to bankruptcy, insolvency, reorganization or other laws of general applicability relating to or affecting mortgagees’ and other creditors’ rights and to general principles of equity (whether considered in a proceeding at law or in equity); said Mortgage has been duly recorded and filed in such manner and in such places as are required by law in order to establish, preserve and protect the lien of said Mortgage;

(6)           The issue and sale of the Notes in an aggregate principal amount not to exceed the amount set forth in the Bond Application and the compliance by the Company with all of the provisions of the Notes, the Mortgage and the Agency Agreement with respect to the Notes and the consummation of the transactions therein contemplated will not conflict with or result in a breach or violation of any of the terms or provisions of, or constitute a default under, any indenture, mortgage, deed of trust, loan agreement or other agreement or instrument to which the Company is a party or by which the Company is bound or to which any of the property or assets of the Company is subject, nor will such actions result in any violation of the provisions of the Restated Articles of Incorporation, as amended or Bylaws, as amended, of the Company or any statute or any order, rule or regulation of any court or governmental agency or body having jurisdiction over the Company or any of its properties;

E-2

(7)           The description of the Company’s property in the Mortgage is adequate to constitute the Mortgage a lien thereon.  The Company has good and marketable fee title to all real property upon which the Mortgage purports to create a lien, except water rights, leases, licenses, franchises, easements and other interests in real property of a similar nature, as to which it has good and valid title, in each case free and clear of all liens, charges and encumbrances other than excepted encumbrances as defined in the Mortgage and the lien of the Mortgage, subject to minor defects and clouds common to property of the size and character of that of the Company.  Such minor defects and clouds are in my opinion not important and do not materially interfere with the operations of the Company or materially detract from the value of its property;

(8)           The Company has such valid franchises, permits, licenses, easements and consents, free from burdensome restrictions, as are required by law for the operation of the Company’s system and as are required for the adequate conduct of its business in the territory which it serves;

(9)           As of their respective effective dates, Registration Statement No. 333-103812 and Registration Statement No. 333-122153, including the Incorporated Documents, and, as of the date of the Prospectus Supplement, the Base Prospectus, as supplemented by the Prospectus Supplement, appeared on their face to comply as to form in all material respects with the requirements of the Act and the Securities Exchange Act of 1934, as amended, and the applicable instructions, rules and regulations of the Securities and Exchange Commission thereunder; the Registration Statement is effective under the Act; and, to my knowledge, no proceedings for a stop order with respect thereto are pending or threatened under Section 8(d) of the Act; and

(10)         All regulatory consents and approvals required to be obtained by the Company from any governmental body or bodies in connection with the Company’s issuance and sale of the Notes in the manner set forth in the Agency Agreement have been obtained and are in effect, except that the order of the Idaho Public Utilities Commission grants authority to sell the Notes only through November 3, 2006; it being understood that I express no opinion as to any consents or approvals required to be obtained, or other actions required to be taken, under state securities or Blue Sky laws of any jurisdiction.

I have no reason to believe that, at their respective effective dates, Registration Statement No. 333-103812 or Registration Statement No. 333-122153, including the Incorporated Documents, contained any untrue statements of a material fact or omitted to state a material fact required to be stated therein or necessary to make the statements therein not misleading or that, as of the date of the Prospectus Supplement, the Base Prospectus, as supplemented by the Prospectus Supplement, contained any untrue statement of a material fact or omitted to state a material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading; it being understood that I express no view as to the financial statements or other financial or accounting data contained or incorporated by reference in the Registration Statement or the Prospectus.  Also, nothing has come to my attention in the course of my examination of the Registration Statement or the Prospectus that has caused me to believe that the Prospectus, as of the date and time of the delivery of this letter, contained any untrue statement of a material fact or omitted to state a

E-3

material fact necessary in order to make the statements therein, in the light of the circumstances under which they were made, not misleading.

Very truly yours,
