IDACORP, Inc.
1221 West Idaho Street
Boise, Idaho  83702-5627

Ladies and Gentlemen:

          We have acted as counsel to IDACORP, Inc., an Idaho corporation (the
"Company"), in connection with the registration statement on Form S-8 (the
"Registration Statement"), which the Company proposes to file on or shortly
after the date hereof under the Securities Act of 1933, as amended (the "Act"),
relating to the issuance and sale by the Company of 1,050,000 shares of its
common stock, without par value (the "Stock"), and the preferred share purchase
rights attached thereto (the "Rights") (the Stock and the Rights collectively
referred to as the "Shares") pursuant to the 2000 Long-Term Incentive and
Compensation Plan, as amended (the "Plan").

          For purposes of this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the Registration
Statement; (ii) the Rights Agreement, dated as of September 10, 1998 between the
Company and Wells Fargo Bank, N.A., as successor to The Bank of New York, as
Rights Agent (the "Rights Agreement"); (iii) the Articles of Incorporation, as
amended, and Amended Bylaws of the Company, as in effect on the date hereof;
(iv) resolutions adopted by the Board of Directors of the Company relating to
the Registration Statement, the Rights Agreement and the issuance and delivery
of the Shares and (v) such other instruments, documents, certificates and
records as we have deemed necessary or appropriate for the purposes hereof. In
such examination we have assumed the genuineness of all signatures, the
authenticity of all documents submitted to us as originals, the conformity to
the original documents of all documents submitted to us as copies and the
authenticity of the originals of such latter documents. As to any facts material
to our opinion, we have, when relevant facts were not independently established,
relied upon the aforesaid Registration Statement, Rights Agreement, Articles of
Incorporation, Amended Bylaws, resolutions, instruments, records, certificates
and documents. We have also assumed the regularity of all corporate procedures.

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

     (1)  The Stock will be validly issued, fully paid and non-assessable and
          the Rights will be legally issued and binding obligations of the
          Company when (i) the Stock shall have been issued, sold and delivered
          pursuant to the terms and provisions of the Plan and for the
          consideration contemplated thereby and (ii) the Rights shall have been
          issued in accordance with the terms of the Rights Agreement and in
          accordance with the actions hereinabove mentioned; and

     (2)  The Stock to be purchased in the open market is validly issued, fully
          paid and non-assessable, and the Rights attached thereto are legally
          issued and binding obligations of the Company.

          The matters relating to the Shares are governed by the law of the
State of Idaho. In regard to the Rights, we note that Section 30-1610 of the
Idaho Control Share Acquisition Law and Section 30-1706 of the Idaho Business
Combination Law each provides that nothing contained in either the Idaho Control
Share Acquisition Law (Sections 30-1601 through 30-1614) or the Idaho Business
Combination Law (Sections 30-1701 through 30-1710), respectively, is intended to
limit the corporate powers or authority of an "issuing public corporation" (as
defined in such statutes), such as the Company, to take actions "which the
directors may appropriately determine to be in furtherance of the protection of
the interests of the corporation and its shareholders, including without
limitation the authority to . . . enter into . . . arrangements," such as the
Rights Agreement, that "deny rights. . . to the holder or holders of at least a
specified number of shares or percentage of share ownership or voting power in
certain circumstances."

          Because we are not aware of any court decision applying the law of the
State of Idaho that addresses the effect of these statutory provisions or the
validity of plans similar to the Rights Agreement, it is difficult to express a
professional judgment as to how a court applying the law of the State of Idaho
would rule with respect to the issues relating to the Rights. Nevertheless, we
are able to advise you of our opinion as expressed herein, which reflects our
professional conclusion concerning how a court applying the law of the State of
Idaho (including, but not limited to, Section 30-1610 of the Idaho Control Share
Acquisition Law and Section 30-1706 of the Idaho Business Combination Law)
likely would rule. Although we are not admitted to practice in the State of
Idaho, we have conferred with Thomas R. Saldin, Esq., Senior Vice President,
General Counsel and Secretary of the Company, for purposes of rendering this
opinion, and we have concluded that a court applying the law of the State of
Idaho, when presented with novel questions concerning takeover matters, such as
the effect of the statutory provisions cited above, the adoption by the Company
of the Rights Agreement and the status of the Rights, most likely would apply
the corporate law of the State of Delaware, the most fully developed body of
corporate law in the United States. Accordingly, in rendering our opinion, we
have assumed that Delaware corporate law, as expressed in court decisions
applying that law,

with which we are familiar, provides an indication of what standards a court
would apply if it were required to apply the law of the State of Idaho
considering the matters relating to the Rights. If, however, such a court did
not apply the corporate law of Delaware to the Rights Agreement and the Rights,
we cannot express a professional judgment as to the conclusions such a court
would reach or as to the effect of such conclusions, whether positive or
negative, on the Rights.

          With respect to this opinion, we do not hold ourselves out as experts
on the laws of any state other than the State of New York. Our opinions
expressed above are limited to the laws of the State of New York, the General
Corporation Law of the State of Delaware and the applicable provisions of the
Constitution of the State of Delaware and the reported judicial decisions
interpreting the Delaware laws, and the federal laws of the United States.
Insofar as this opinion involves matters of the law of the State of Idaho, we
have relied upon an opinion of even date herewith addressed to you by Thomas R.
Saldin, Senior Vice President, General Counsel and Secretary of the Company.

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and the reference to our firm contained therein under the
heading "Interests of Named Experts and Counsel." In giving such consent, we do
not thereby concede that we are within the category of persons whose consent is
required under Section 7 of the Securities Act or the rules and regulations of
the Commission thereunder.

                                    Very truly yours,


                                    /s/ LeBoeuf, Lamb, Greene & MacRae, LLP
