                              NEVADA POWER COMPANY

                              OFFICER'S CERTIFICATE

                                  April 4, 2002


     I, the undersigned officer of Nevada Power Company (the "Company"), do
hereby certify that I am an Authorized Officer of the Company as such term is
defined in the Indenture (as defined herein). I am delivering this certificate
pursuant to the authority granted in the Board Resolutions of the Company dated
November 6, 2001, and Sections 1.04, 2.01, 3.01, 4.01(a) and 4.02(b)(i) of the
General and Refunding Mortgage Indenture dated as of May 1, 2001, as heretofore
amended and supplemented to the date hereof (as heretofore amended and
supplemented, the "Indenture"), between the Company and The Bank of New York, as
Trustee (the "Trustee"). Terms used herein and not otherwise defined herein
shall have the meanings assigned to them in the Indenture, unless the context
clearly requires otherwise. Based upon the foregoing, I hereby certify on behalf
of the Company as follows:

     1.   The terms and conditions of the Securities of the series described in
this Officer's Certificate are as follows (the lettered subdivisions set forth
in this Paragraph 1 corresponding to the lettered subdivisions of Section 3.01
of the Indenture):

     (a) The Securities of the third series to be issued under the Indenture
     shall be designated "General and Refunding Mortgage Bonds, Series C, due
     November 28, 2002" (the "Bonds").

     (b) The Bonds shall be authenticated and delivered in the aggregate
     principal amount of $200,000,000.

     (c) Not applicable.

     (d) The principal of all Bonds shall be payable by the Company in whole or
     in installments on such date or dates as the Company has any obligations
     under the Credit Agreement to repay any Loans (as defined in the Credit
     Agreement) to the Lenders (whether upon scheduled maturity, required
     prepayment, acceleration, demand or otherwise), but not later than November
     28, 2002. The amount of principal of the Bonds payable by the Company on
     any such date shall equal the aggregate principal amount of the Loans due
     and payable on such date pursuant to the Credit Agreement (but, in no
     event, shall exceed the aggregate principal amount of the Bonds). The
     obligation of the Company to make any payment of the principal on the Bonds
     shall be fully or partially, as the case may be, deemed to have been paid
     or otherwise satisfied and discharged to the extent that the Company has
     paid the principal then due and payable on the Loans made pursuant to the
     Credit Agreement, but any such payment shall not reduce the principal
     amount of the Bonds unless the aggregate amount of the Lenders' Commitments
     (as defined in the Credit Agreement) is irrevocably reduced concurrently
     with such payment.






     If a Default (as defined in the Credit Agreement) in the payment of
     principal of any Loans shall occur under Section 7.01 of the Credit
     Agreement, it shall be deemed to be a default, for the purposes of Section
     10.01 of the Indenture, in payment of an amount of principal of the Bonds
     equal to the amount of such unpaid principal of the Loans (but, in no
     event, in excess of the aggregate principal amount of the Bonds).

     (e) The Bonds shall bear interest from the time hereinafter provided at
     such rate per annum as shall cause the amount of interest payable on each
     Interest Payment Date (as hereinafter defined) on the Bonds to equal the
     amount of interest and fees payable on such Interest Payment Date under the
     Credit Agreement. Such interest on the Bonds shall be payable on the same
     dates as interest and/or fees are payable from time to time pursuant to the
     Credit Agreement (each such date herein called an "Interest Payment Date"),
     until the maturity of the Bonds, or, in the case the Administrative Agent
     shall demand redemption of the Bonds, until the redemption date, or, in the
     case of any default by the Company in the payment of the principal due on
     the Bonds, until the Company's obligation with respect to the payment of
     such principal shall be discharged as provided in the Indenture. The amount
     of interest and fees payable from time to time under the Credit Agreement,
     the basis on which such interest and fees are computed and the dates on
     which such interest and fees are payable are set forth in the Credit
     Agreement. Each Bond shall bear interest from the later of the date of
     initial authentication of such Bond or the most recent Interest Payment
     Date to which interest has been paid. The obligation of the Company to make
     any payment of interest on the Bonds shall be fully or partially, as the
     case may be, deemed to have been paid or otherwise satisfied and discharged
     to the extent that the Company has paid the interest on the Loans and fees
     then due and payable pursuant to the Credit Agreement. If a Default (as
     defined in the Credit Agreement) in the payment of interest or fees shall
     occur under Section 7.01 of the Credit Agreement, it shall be deemed to be
     a default, for purposes of Section 10.01 of the Indenture, in the payment
     of an amount of interest on the Bonds equal to the amount of such unpaid
     interest on the Loans and such fees.

     (f) The Corporate Trust Office of The Bank of New York in New York, New
     York shall be the place at which (i) the principal of and interest on the
     Bonds shall be payable, (ii) registration of transfer of the Bonds may be
     effected, (iii) exchanges of the Bonds may be effected and (iv) notices and
     demands to or upon the Company in respect of the Bonds and the Indenture
     may be served; and The Bank of New York shall be the Security Registrar for
     the Bonds; PROVIDED, HOWEVER, that the Company reserves the right to
     change, by one or more Officer's Certificates, with the consent of the
     Administrative Agent, any such place or the Security Registrar; and
     provided, further, that the Company reserves the right to designate, by one
     or more Officer's Certificates, its principal office in Las Vegas, Nevada
     as any such place or itself as the Security Registrar; PROVIDED, HOWEVER,
     that there shall be only a single Security Registrar for the Bonds. The
     principal of the Bonds shall be payable without the presentment or
     surrender thereof.

     (g) Not applicable.

     (h) Not applicable.

                                       2

     later than November 28, 2002, unless sooner paid, and shall bear interest
     at the rate specified in subsection (e) above. The Bonds may be executed by
     the Company and delivered to the Trustee for authentication and delivery.
     The principal of and interest on the Bonds shall be payable at the
     Corporate Trust Office of the Trustee in New York, New York.

          The single Bond shall be identified by the number C-1 and shall upon
     issuance be delivered by the Company to, and registered in the name of, the
     Administrative Agent, on behalf of itself and the Lenders, and shall be
     transferable only as required to effect an assignment thereof to a
     successor or an assign of the Administrative Agent under the Credit
     Agreement. The Bonds are to be issued to the Administrative Agent as
     security for the payment by the Company of its Obligations (as defined in
     the Credit Agreement). The single Bond shall be held by the Administrative
     Agent subject to the terms of the Bond Delivery Agreement, dated as of
     April 4, 2002, between the Company and the Administrative Agent.

          Bonds issued upon transfer shall be numbered consecutively from C-2
     upwards and issued in the same $200,000,000 denomination but, to the extent
     that the aggregate of the Lenders Commitments under the Credit Agreement
     shall have theretofore been reduced, the registered holder thereof shall
     duly note on the Bonds like reduction in the amount of principal in the
     Schedule of Prepayments to such Bond and upon any transfer of said Bond,
     such Schedule of Prepayments shall transfer to the subsequently issued
     Bond.

     (r) Not applicable.

     (s) The holder of the Bond by acceptance of the Bond agrees to restrictions
     on transfer and to waivers of certain rights of exchange as set forth
     herein. In addition, the


                                       3




     Bond has not been registered under the Securities Act of 1933 and the Bond
     may not be transferred without compliance with applicable securities laws.
     The Bond is not transferable except to a successor to the Administrative
     Agent under the Credit Agreement.

     (t) For purposes of the Bonds, "Business Day" shall mean any day that is
     not a Saturday, Sunday or other day on which commercial banks in Los
     Angeles, California or New York, New York are authorized or required by law
     to remain closed.

     (u) The Trustee may conclusively presume that the obligation of the Company
     to pay the principal of and interest on the Bond shall have been fully
     satisfied and discharged unless and until it shall have received a written
     notice from the Administrative Agent, signed by an Authorized Officer of
     the Administrative Agent and attested by the Secretary or an Assistant
     Secretary of the Administrative Agent, stating that the payment of
     principal of or interest on the Bond has not been fully paid when due and
     specifying the amount of funds required to make such payment.

          The Bonds shall have such other terms and provisions as are provided
     in the form thereof attached hereto as EXHIBIT A, and shall be issued in
