                              OFFICER'S CERTIFICATE

                                October 30, 2002


     I, the undersigned officer of Sierra Pacific 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
September 10, 2002, 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
supplemented to the date hereof (as heretofore 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
     October 31, 2005" (the "Bonds").

     (b)  The Bonds shall be authenticated and delivered in the aggregate
     principal amount of $100,000,000.

     (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 Term Loan Agreement dated as of October 30, 2002 (the "Loan
     Agreement") among the Company, Lehman Brothers Inc., as advisor, sole lead
     arranger and sole bookrunner, Lehman Commercial Paper Inc., as
     administrative agent (in such capacity, the "Administrative Agent") and as
     syndication agent and the other financial institutions or entities party
     thereto from time to time (the "Lenders") to repay any Loans (as defined in
     the Loan Agreement) to the Lenders (whether upon scheduled maturity,
     optional prepayment, required prepayment, acceleration, demand or
     otherwise), but not later than October 31, 2005. The amount of principal of
     the Bonds payable by the Company on any such date shall equal the aggregate
     principal amount of the Loans (as defined in the Loan Agreement) due and
     payable on such date pursuant to the Loan 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 Loan
     Agreement. If a Default (as defined in the Loan Agreement) in the payment
     of principal of any Loans shall occur under Section 7(a) of the Loan
     Agreement, it shall be deemed to be a default, for the purposes of Section
     10.01(b) 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, fees or such other amounts payable by the Company on
     such Interest Payment Date under the Loan Agreement. Such interest on the
     Bonds shall be payable on the same dates as interest and, fees or such
     other amounts are payable by the Company from time to time under the Loan
     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, fees or such other amounts payable by the Company from time to
     time under the Loan Agreement, the basis on which such interest, fees and
     such other amounts are computed and the dates on which such interest, fees
     and such other amounts are payable are set forth in the Loan Agreement.
     Each Bond shall bear interest (a) from the most recent Interest Payment
     Date, or (b) if no interest has been paid on the Bond, then from the date
     of the initial authentication of the Bond. 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 Loan Agreement. If a
     Default (as defined in the Loan Agreement) in the payment of interest, fees
     or such other amounts by the Company shall occur under Section 7(a) of the
     Loan Agreement, it shall be deemed to be a default, for purposes of Section
     10.01(a) 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, fees and
     such other amounts.

     (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 Reno, Nevada as any
     such place or itself as the Security Registrar; PROVIDED, HOWEVER,

                                       2


     that there shall be only a single Security Registrar for the Bonds. The

     ($100,000,000). The Bonds shall be dated October 30, 2002, shall mature no
     later than October 31, 2005 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 Loan
     Agreement. The Bonds are to be delivered to the Administrative Agent as
     security for the payment by the Company of its Obligations (as defined in
     the Loan Agreement). The single Bond shall be held by the Administrative
     Agent subject to the terms of the Bond Delivery Agreement, dated as of
     October 30, 2002, between the Company and the Administrative Agent.

          Bonds issued upon transfer shall be numbered consecutively from C-2

     (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 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 Loan 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
     substantially such form.
