          All documents that we subsequently file under Section 13(a), 13(c), 14
or 15(d) of the Securities Exchange Act of 1934, other than any information that
we furnish rather than file with the Securities and Exchange Commission pursuant
to certain items of Form 8-K, after the effective date of this registration
statement and prior to filing a post-effective amendment that indicates that all
securities offered hereby have been sold or that deregisters all securities that
have not been sold shall be deemed to be incorporated by reference in this
registration statement and to be a part hereof from the date of filing of such
documents.

Item 5.  Interests of Named Experts and Counsel.
-------  ---------------------------------------

          Thomas R. Saldin, Esq., our Senior Vice President, General Counsel and
Secretary, and LeBoeuf, Lamb, Greene & MacRae, LLP, New York, New York, a
limited liability partnership including professional corporations, have given
their opinions on the legality of the common stock and the preferred share
purchase rights offered pursuant to this registration statement. LeBoeuf, Lamb,
Greene & MacRae, LLP relied upon the opinion of Mr. Saldin as to matters of
Idaho law.

          As of May 1, 2005, Mr. Saldin owned 3,462 shares of IDACORP common
stock. Mr. Saldin is acquiring additional shares of IDACORP common stock at
regular intervals through employee stock plans.

Item 6.  Indemnification of Directors and Officers.
-------  ------------------------------------------

          Sections 30-1-850 et seq. of the Idaho Business Corporation Act
provide for indemnification of IDACORP's directors and officers in a variety of
circumstances.


                                      II-1


          Article VIII of IDACORP's articles of incorporation, as amended,
provides that IDACORP shall indemnify its directors and officers against
liability and expenses and shall advance expenses to its directors and officers
in connection with any proceeding to the fullest extent permitted by the Idaho
Business Corporation Act as now in effect or as it may be amended or substituted
from time to time. Article VI of IDACORP's bylaws provides that IDACORP shall
have the power to purchase and maintain insurance on behalf of any director,
officer, employee or agent against liability and expenses in connection with any
proceeding, to the extent permitted under applicable law. Article VI further
provides that IDACORP may enter into indemnification agreements with any
director, officer, employee or agent to the extent permitted under any
applicable law.

          IDACORP has liability insurance protecting its directors and officers
against liability by reason of their being or having been directors or officers.
In addition, IDACORP has entered into indemnification agreements with its
directors and officers to provide for indemnification to the maximum extent
permitted by law.

Item 9.  Undertakings.
-------  -------------

          The undersigned registrant hereby undertakes:

          (1) To file, during any period in which offers or sales are being
made, a post-effective amendment to this registration statement:

          (i)  To include any prospectus required by section 10(a)(3) of the
          Securities Act of 1933;

          (ii) To reflect in the prospectus any facts or events arising after
          the effective date of the registration statement (or the most recent
          post-effective amendment thereof) which, individually or in the
          aggregate, represent a fundamental change in the information set forth
          in the registration statement. Notwithstanding the foregoing, any
          increase or decrease in volume of securities offered (if the total
          dollar value of securities offered would not exceed that which was
          registered) and any deviation from the low or high end of the
          estimated maximum offering range may be reflected in the form of
          prospectus filed with the Commission pursuant to Rule 424(b) if, in
          the aggregate, the changes in volume and price represent no more than
          a 20 percent change in the maximum aggregate offering price set forth
          in the "Calculation of Registration Fee" table in the effective
          registration statement;

          (iii)To include any material information with respect to the plan of
          distribution not previously disclosed in the registration statement or
          any material change to such information in the registration statement;

provided, however, that paragraphs (1)(i) and (1)(ii) do not apply if the
registration statement is on Form S-3, Form S-8 or Form F-3 and the information
required to be included in a post-effective amendment by those paragraphs is
contained in periodic reports filed with or furnished to the Securities and
Exchange Commission by the registrant pursuant to section 13 or section 15(d) of
the Securities Exchange Act of 1934 that are incorporated by reference in the
registration statement.

          (2) That, for the purpose of determining any liability under the
Securities Act of 1933, each such post-effective amendment shall be deemed to be
a new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.


                                      II-3


          (3) To remove from registration by means of a post-effective amendment
any of the securities being registered that remain unsold at the termination of
the offering.

          (4) That, for purposes of determining any liability under the
Securities Act of 1933, each filing of the registrant's annual report pursuant
to section 13(a) or section 15(d) of the Securities Exchange Act of 1934 (and,
where applicable, each filing of an employee benefit plan's annual report
pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is
incorporated by reference in the registration statement shall be deemed to be a
new registration statement relating to the securities offered therein, and the
offering of such securities at that time shall be deemed to be the initial bona
fide offering thereof.

          Insofar as indemnification for liabilities arising under the
Securities Act of 1933 may be permitted to directors, officers and controlling
persons of the registrant pursuant to the provisions described under Item 6
above, or otherwise, the registrant has been advised that in the opinion of the
Securities and Exchange Commission such indemnification is against public policy
as expressed in the Act and is, therefore, unenforceable. In the event that a
claim for indemnification against such liabilities (other than the payment by
the registrant of expenses incurred or paid by a director, officer or
controlling person of the registrant in the successful defense of any action,
suit or proceeding) is asserted by such director, officer or controlling person
in connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the Act and
will be governed by the final adjudication of such issue.


                                      II-4


                                POWER OF ATTORNEY


          Each director and/or officer of the issuer whose signature appears
below hereby authorizes any agent for service named on the cover of this
Registration Statement to execute in the name of each such person, and to file
with the Securities and Exchange Commission, any and all amendments, including
post-effective amendments, to the Registration Statement, and appoints any such
agent for service as attorney-in-fact to sign in his behalf individually and in
each capacity stated below and file any such amendments to the Registration
Statement, and the issuer hereby confers like authority to sign and file on its
behalf.

                                   SIGNATURES

          The Registrant. Pursuant to the requirements of the Securities Act of
1933, the registrant certifies that it has reasonable grounds to believe that it
meets all of the requirements for filing on Form S-8 and has duly caused this
Registration Statement to be signed on its behalf by the undersigned, thereunto
duly authorized, in the City of Boise and State of Idaho, on the 25th day of
May, 2005.
