Exhibit 10(D)

                         CHANGE IN CONTROL AGREEMENT
                         ---------------------------

         THIS AGREEMENT, dated May 21, 2001, is made by and between Sierra
Pacific Resources, a Nevada corporation (the "Company"), and John E. Brown
(the "Executive").

         WHEREAS, the Company considers it essential to the best interests of
its stockholders to foster the continued employment of key management
personnel; and

         WHEREAS, the Board recognizes that, as is the case with many publicly
held corporations, the possibility of a Change in Control exists and that such
possibility, and the uncertainty and questions which it may raise among
management, may result in the departure or distraction of management personnel
to the detriment of the Company and its stockholders; and

         WHEREAS, the Board has determined that appropriate steps should be
taken to reinforce and encourage the continued attention and dedication of
members of the management of the Company and its subsidiaries (collectively,
"Sierra"), including the Executive, to their assigned duties without
distraction in the face of potentially dasturbing circumstances arising from
the possibility of a Change in Control;

         NOW, THEREFORE, in consideration of the premises and the mutual
covenants herein contained, the Company and the Executive hereby agree as
follows:

         1. Defined Terms.  The definitions of capitalized terms used in this
            -------------
Agreement are provided in the last Section hereof.

         2. Term of Agreement. The term of this Agreement shall commence on
            -----------------
the date hereof and shall continue in effect through December 31, 2004;
provided, however, that if a Change in Control shall have occurred during the
- --------  -------
Term, the Term shall expire no earlier than twenty-four (24) months beyond the
month in which such Change in Control occurred; and further provided, however,
                                                    ------- --------  -------
that if a Potential Change in Control shall have occurred during the Term, the
Term shall expire no earlier than the later of (a) December 31, 2004, (b) the
date on which such potential Change in Control shall have been terminated, or
(c) 24 months beyond the

                                      1




date on which such potential Change in Control shall have resulted in a Change
of Control.

         3.  Company's Covenants Summarized.  In order to induce the Executive
             ------------------------------
to remain if the employ of Sierra and in consideration of the Executive's
covenants set forth in Section 4 hereof, the Company agrees, under the
conditions described herein, to pay the Executive the Severance Payments and
the other payments and benefits described herein. Except as provided in Section
9.1 hereof, no Severance Payments shall be payable under this Agreement unless
there shall have been (or, under the terms of the second sentence of Section
6.1 hereof, there shall be deemed to have been) a termination of the
Executive's employment with Sierra following a Change in Control or potential
Change in Control and during the Term. This Agreement shall not be construed as
creating an express or implied contract of employment and, except as otherwise
agreed in writing between the Executive and Sierra, the Executive shall not
have any right to be retained in the employ of Sierra. The obligations of the
Company hereunder shall be deemed satisfied to the extent payments are made by
Sierra Pacific Power, Nevada Power, or any affiliate of the Company or any
successor to the Company or any sucessor to any affiliate of the Company.

         4. The Executive's Covenants.  The Executive agrees that, subject to
            -------------------------
the terms and conditions of this Agreement, in the event of a Potential Change
in Control during the Term, the Executive will remain in the employ of the
Company until the earliest of (i) a date which is six (6) months from the date
of such Potential Change of Control, (ii) the date of a Change in Control,
(iii) the date of termination by the Executive of the Executive's employment
for Good Reason or by reason of death, Disability or Retirement, or (iv) the
termination by Sierra of the Executive's employment for any reason.

         5. Compensation Other Than Severance Payments.
            ------------------------------------------

         5.1 Following a Change in Control or potential Change in Control and
during the Term, during any period that the Executive fails to perform the
Executive's full-time duties with Sierra as a result of incapacity due to
physical or mental illness, the Company shall pay the Executive's full salary
to the Executive at the rate in effect at the commencement of any such period,
together with all compensation and benefits payable to the Executive under the
terms of any compensation or benefit plan, program or arrangement maintained by
Sierra during such period, until the Executive's employment is terminated by
Sierra for Disabilitq.

         5.2 If the Executive's employment shall be terminated for any reason
following a Change in Control or potential Change in Control and during the
Term, the Company shall pay the Executive's full salary to the Executive
through the Date of Termination at the rate in effect immediately prior to the
Date of Termination or, if higher, the rate in effect immediately prior to the
first occurrence of an event or circumstance constituting Good Reason, together
with all compensation and benefits

                                      2



payable to the Executive through the Date of Termination under the terms of
Sierra compensation and benefit plans, programs or arrangements as in effect
immediately prior to the Date of Termination or, if more favorable to the
Executive, as in effect immediately prior to the first occurrence of an event
or circumstance constituting Good Reason.

         5.3 If the Executive's employment shall be terminated for any
reason following a Change in Control or Potential Change in Control and during
the Term, the Company shall pay to the Executive the Executive's normal
post-termination compensation and benefits (other than any severance payments
forgone under Section 6.1a) as such payments become due, provided that the
Executive is eligible or entitled to such compensation and benefits under the
terms and conditions of any such plan or program in effect and provided further
that the Executive fully complied with all conditions and requirements of any
such plan or program, and provided further that such payments or benefits are
not otherwise precluded under the terms of this Agreement. Such post-termination
compensation and benefits shall be determined under, and paid in accordance
with, Sierra's retirement, insurance and other compensation or benefit plans,
programs and arrangements as in effect immediately prior to the Date of
Termination or, if more favorable to the Executive, as in effect immediately
prior to the occurrence of the first event or circumstance constituting Good
Reason.

         6. Severance Payments.
            ------------------

         6.1  Subject to Section 6.2 hereof, and subject to the limitations
specified in Sections 15.G.V, 15.O, in the case of an impacted Executive which
                           -
provisions shall control over the provisions of these Sections 6.1 and 6.2 if
the Executive's employment is terminated following a Change in Control or
Potential Change in Control and during the Term, other than (A) by Sierra for
Cause, (B) by reason of death or Disability, or (C) by the Executive without
Good Reason, then Sierra shall pay the Executive the amounts, and provide the
Executive the benefits, described in this Section 6.1 ("Severance Payments"),
in addition to any payments and benefits to which the Executive is entitled
under Section 5 hereof. For purposes of this Agreement, the Executive's
employment shall be deemed to have been terminated following a Change in
Control by Sierra without Cause or by the Executive with Good Reason, if (i)
the Executive's employment is terminated by Sierra without Cause prior to a
Change in Control (whether or not a Change in Control ever occurs) and such
termination was at the request or direction of a Person who has entered into an
agreement with the Company the consummation of which would constitute a Change
in Control, (ii) the Executive terminates his employment for Good Reason prior
to a Change in Control (whether or not a Change in Control ever occurs) and the
circumstance or event which constitutes Good Reason occurs at the request or
direction of such Person, or (iii) the Executive's employment is terminated by
Sierra without Cause or by the Executive for Good Reason and such termination
or the circumstance or event which constitutes Good Reason is otherwise in
connection with or in anticipation of a

                                      3



Change in Control (whether or not a Change in Control ever occurs). For
purposes of any determination regarding the applicability of the immediately
preceding sentence, any position taken by the Executive shall be presumed to be
correct undess the Company establishes to the Board by clear and convincing
evidence that such position is not correct.

              (A) In lieu of any further salary payments to the Executive for
     periods subsequent to the Date of Termination and in lieu of any severance
     benefit otherwise payable to the Executive under or pursuant to any
     contract or plan, except for any severance benefits relating to or
     resulting from the Supplemental Executive Retirement Plan (provided the
     Executive is a participant in the Plan), whether as a consequence of a
     Change in Control or otherwise, and subject to the provisions of Section
     6.2(a), the Company shall pay to the Executive a lump sum severance
     payment, in cash, equal to two times the sum of (i) the Executive's base
     salary as in effect immediately prior to the Date of Termination or, if
     higher, in effect immediately prior to the first occurrence of an event or
     circumstance constituting Good Reason, and (ii) the target annual cash
     incentive award applicable to the Executive pursuant to any annual cash
     bonus or annual cash incentive plan maintained by Sierra in respect of the
     fiscal year ending immediately prior to the fiscal year in which occurs
     the Date of Termination or, if higher, immediately prior to the fiscal
     year in which occurs the first event or circumstance constituting Good
     Reason.

              (B) For the twenty-four (24) month period immediately following
     the Date of Termination, the Company shall arrange to provide the
     Executive and his dependents life, disability, accident and health
     insurance benefits substantially similar to those provided to the
     Executive and his dependents immediately prior to the Date of Termination
     or, if more favorable to the Executive, those provided to the Executive
     and his dependents immediately prior to the first occurrence of an event
     or circumstance constituting Good Reason, at no greater cost to the
     Executive than the cost to the Executive immediately prior to such date or
     occurrence; provided, however, that, unless the Executive consents to a
                 --------  -------
     different method (after taking into account the effect of such method on
     the calculation of "parachute payments" pursuant to Section 6.2 hereof),
     such health insurance benefits shall be provided through a third-party
     insurer. Benefits otherwise receivable by the Executive pursuant to this
     Section 6.1(B) shall be reduced to the extent benefits of the same type
     are received by or made available to the Executive during the twenty-four
     (24) month period following the Executive's termination of employment (and
     any such benefits received by or made available to the Executive shall be
     reported to the Company by the Executive); provided, however, that the
                                                --------  -------
     Company shall reimburse the Executive for the excess, if any, of the cost
     of such benefits to the Executive over such cost immediately prior to the
     Date of Termination or, if more favorable to the Executive, the first
     occurrence of an event or circumstance constituting Good Reason. If the
     Severance Payments

                                      4



     shall be decreased pursuant to Section 6.2 hereof, and the Section 6.1(B)
     benefits which remain payable after the application of Section 6.2 hereof
     are thereafter reduced pursuant to the immediately preceding sentence, the
     Company shall, no later than five (5) business days following such
     reduction, pay to the Executive the least of (a) the amount of the
     decrease made in the Severance Payments pursuant to Section 6.2 hereof,
     (b) the amount of the subsequent reduction in these Section 6.1(B)
     benefits, or (c) the maximum amount which can be paid to the Executive
     without being, or causing any other payment to be, nondeductible by reason
     of Section 280G of the Code.

              (C) Notwithstanding any provision of any annual or long-term
     incentive plan to the contrary, the Company shall pay to the Executive a
     lump sum amount, in cash, equal to the sum of (i) any unpaid incentive
     compensation which has been allocated or awarded to the Executive for a
     completed fiscal year or other measuring period preceding the Date of
     Termination under any such plan and which, as of the Date of Termination,
     is contingent only upon the continued employment of the Executive to a
     subsequent date, and (ii) a pro rata portion to the Date of Termination of
     the aggregate value of all contingent incentive compensation awards to the
     Executive for all then uncompleted periods under any such plan, calculated
     as to each such award by multiplying the award that the Executive would
     have earned on the last day of the performance award period, assuming the
     achievement, at the target level of the individual and corporate
     performance goals established with respect to such award, by the fraction
     obtained by dividing the number of full months and any fractional portion
     of a month during such performance award period through the Date of
     Termination by the total number of months contained in such performance
     award period.

              (D) In addition to the retirement benefits to which the Executive
     is entitled under each Pension Plan or any successor plan thereto, the
     Company shall pay the Executive a lump sum amount, in cash, equal to the
     excess of (i) the actuarial equivalent of the aggregate retirement pension
     (taking into account any early retirement subsidies associated therewith
     and determined as a straight life annuity commencing at the date (but in
     no event earlier than the third anniversary of the Date of Termination) as
     of which the actuarial equivalent of such annuity is greatest) which the
     Executive would have accrued under the terms of all Pension Plans (without
     regard to any amendment to any Pension Plan made subsequent to a Change in
     Control and on or prior to the Date of Termination, which amendment
     adversely affects in any manner the computation of retirement benefits
     thereunder), determined as if the Executive were fully vested thereunder
     and had accumulated (after the Date of Termination) twenty-four (24)
     additional months of service credit thereunder and had been credited under
     each Pension Plan during such period with compensation equal to the
     Executive's compensation (as defined in such Pension Plan) during the
     twelve (12) months immediately preceding the Date of Termination gr, if
     higher, during

                                      5



     the twelve months immediately prior to the first occurrence of an event or
     circumstance constituting Good Reason, over (ii) the actuarial equivalent
     of the aggregate retirement pension (taking into account any early
     retirement subsidies associated therewith and determined as a straight
     life annuity commencing at the date (but in no event earlier than the Date
     of Termination) as of which the actuarial equivalent of such annuity is
     greatest) which the Executive had accrued pursuant to the provisions of
     the Pension Plans as of the Date of Termination. For purposes of this
     Section 6.1(D), "actuarial equivalent" shall be determined using the same
     assumptions utilized under the Sierra Pacific Power Company Retirement
     Plan immediately prior to the Date of Termination. or, if more favorable
     to the Executive, immediately prior to the first occurrence of an event or
     circumstance constituting Good Reason.

              (E) If the Executive would have become entitled to benefits under
     Sierra's post-retirement health care or life insurance plans, as in effect
     immediately prior to the Date of Termination or, if more favorable to the
     Executive, as in effect immediately prior to the first occurrence of an
     event or circumstance constituting Good Reason, had the Executive's
     employment terminated at any time during the period of twenty-four (24)
     months after the Date of Termination, the Company shall provide such
     post-retirement health care or life insurance benefits to the Executive
     and the Executive's dependents commencing on the later of (i) the date on
     which such coverage would have first become available and (ii) the date on
     which benefits described in subsection (B) of this Section 6.1 terminate.

          6.2  (A)  Notwithstanding any other provisions of this Agreement, in
the event that any payment or benefit received or to be received by the
Executive in connection with a Change in Control or the termination of the
Executive's employment (whether pursuant to the terms of this Agreement or any
other plan, arrangement or agreement with the Company, any Person whose actions
result in a Change in Control or any Person affiliated with the Company or such
Person) (all such payments and benefits, including the Severance Payments,
being hereinafter called "Total Payments") would be subject (in whole or part),
to the Excise Tax, then, after taking into account any reduction in the Total
Payments provided by reason of section 280G of the Code in such other plan,
arrangement or agreement, the cash Severance Payments shall first be reduced,
and the non-cash Severance Payments shall thereafter be reduced, to the extent
necessary so that no portion of the Total Payments is subject to the Excise Tax
but only if (A) the net amount of such Total Payments, as so reduced (and after
subtracting the net amount of federal, state and local income taxes on such
reduced Total Payments) is greater than or equal to (B) the net amount of such
Total Payments without such reduction (but after subtracting the net amount of
federal, state and local income taxes on such Total Payments and the amount of
Excise Tax to which the Executive would be subject in respect of such unreduced
Total Payments); provided, however, that the Executive may elect to have the
                 --------  -------
non-cash Severance Payments reduced (or eliminated) prior to any reduction of
the cash Severance Payments.

                                      6



          (B)  For  purposes of determining  whether and the extent to which
the Total Payments will be subject to the Excise Tax, (i) no portion of the
Total Payments the receipt or enjoyment of which the Executive shall have
waived at such time and in such manner as not to constitute a "payment" within
the meaning of Section 280G(b) gf the Code shall be taken into account, (ii) no
portion of the Total Payments shall be taken into account which, in the opinion
of tax counsel ("Tax Counsel") reasonably acceptable to the Executive and
selected by the accounting firm (the "Auditor") which was, immediately prior to
the Change in Control, the Company's independent auditor, does not constitute a
"parachute payment" within the meaning of Section 280G(b)(2) of the Code
(including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating
the Excise Tax, no portion of such Total Payments shall be taken into account
which, in the opinion of Tax Counsel, constitutes reasonable compensation for
services actually rendered, within the meaning of Section 280G(b)(4)(B) of the
Code, in excess of the Base Amount allocable to such reasonable compensation,
and (iii) the value of any non-cash benefit or any deferred payment or benefit
included in the Total Payments shall be determined by the Auditor in accordance
with the principles of Sections 280G(d)(3) and (4) of the Code.

          (C)  At the time that  payments  are made under this  Agreement,  the
Company shall provide the Executive with a written statement setting forth the
manner in which such payments were calculated and the basis for such
calculations including, without limitation, any opinions or other advice the
Company has received from Tax Counsel, the Auditor or other advisors or
consultants (and any such opinions or advice which are in writing shall be
attached to the statement). If the Executive objects to the Company's
calculations, the Company shall pay to the Executive such portion of the
Severance Payments (up to 100% thereof) as the Executive with concurrence of
tax counsel determine are necessary to result in the proper application of
subsection A of this Section 6.2.

          6.3 The payments provided in subsections (A), (C) and (D) of Section
6.1 hereof shall be made not later than the fifth day following the Date of
Termination; provided, however, that if the amounts of such payments, and the
             --------  -------
limitation on such payments set forth in Section 6.2 hereof, cannot be finally
determined on or before such day, the Company shall pay to the Executive on
such day an estimate, as determined in good faith by the Executive of the
minimum amount of such payments to which the Executive is clearly entitled, but
in no event to exceed two times the sum of base pay and target annual cash
incentive, and shall pay the remainder of such payments (together with interest
on the unpaid remainder (or on all such payments to the extent the Company
fails to make such payments when due) at 120% of the rate provided in Section
1274(b)(2)(B) of the Code) as soon as the amount thereof can be determined but
in no event later than the thirtieth (30th) day after the Date of Termination.
In the eveft that the amount of the estimated payments exceeds the amount
subsequently determined to have been due, such excess shall constitute a loan
by the Company to the Executive, payable

                                      7



on the fifth (5th) business day after demand by the Company (together with
interest at 120% of the rate provided in Section 1274(b)(2)(B) of the Code).

          6.4 The Company also shall pay to the Executive all legal fees and
expenses incurred by the Executive in disputing in good faith any issue
hereunder relating to the termination of the Executive's employment, in seeking
in good faith to obtain or enforce any benefit or right provided by this
Agreement or in connection with any tax audit or proceeding to the extent
attributable to the application of Section 4999 of the Code to any payment or
benefit provided hereunder. Such payments shall be made within five (5)
business days after delivery of the Executive's written requests for payment
accompanied with such evidence of fees and expenses incurred as the Company
reasonably may require.

          6.5 Notwithstanding any other provision of this agreement, except as
otherwise permitted by this Agreement, if the Executive is entitled to and
claims benefits under or pursuant to any other change in control agreement
entered into between Company or Sierra and the executive, or any terms or
conditions thereunder, the executive shall not be entitled to any of the
severance benefits or any other benefits under this agreement or terms or
conditions of this agreement.

          7. Termination Procedures and Compensation During Dispute.
             ------------------------------------------------------

          7.1 Notice of Termination. After a Change in Control or potential
              ---------------------
Change in Control and during the Term, any purported termination of the
Executive's employment (other than by reason of death) shall be communicated by
written Notice of Termination from one party hereto to the other party hereto
in accordance with Section 10 hereof. For purposes of this Agreement, a "Notice
of Termination" shall mean a notice which shall indicate the specific
termination provision in this Agreement relied upon and shall set forth in
reasonable detail the facts and circumstances claimed to provide a basis for
termination of the Executive's employment under the provision so indicated.
Further, a Notice of Termination for Cause is required to include a copy of a
resolution duly adopted by the affirmative vote of not less than three-quarters
(3/4) of the entire membership of the Board at a meeting of the Board which was
called and held for the purpose of considering such termination (after
reasonable notice to the Executive and an opportunity for the Executive,
together with the Executive's counsel, to be heard before the Board) finding
that, in the good faith opinion of the Board, the Executive was guilty of
conduct set forth in clause (i) or (ii) of the definition of Cause herein, and
specifying the particulars thereof in detail.

          7.2 Date of Termination. "Date of Termination," with respect to any
              -------------------
purported termination of the Executive's employment after a Change in Control
or potential Change in Control and during the Term, shall mean (i) if the
Executive's employment is terminated for Disability, thirty (30) days after
Notice of Termination is given (provided that the Executive shall not have
returned to the full-time performance of the Executive's duties during such
thirty (30) day period), and (ii) if

                                      8



the Executive's employment is terminated for any other reason, the date
specified in the Notice of Termination (which, in the case of a termination by
Sierra, shall not be less than thirty (30) days (except in the case of a
termination for Cause) and, in the case of a termination by the Executive,
shall not be less than fifteen (15) days nor more than sixty (60) days,
respectively, from the date such Notice of Termination is given).

          7.3 Dispute Concerning Termination. If within fifteen (15) days after
              ------------------------------
any Notice of Termination is given, or, if later, prior to the Date of
Termination (as determined without regard to this Section 7.3), the party
receiving such Notice of Termination notifies the other party that a dispute
exists concerning the termination, the Date of Termination shall be extended
until the earlier of (i) the date on which the Term ends or (ii) the date on
which the dispute is finally resolved, either by mutual written agreement of
the parties or by a final judgment, order or decree of an arbitrator or a court
of competent jurisdiction (which is not appealable or with respect to which the
time for appeal therefrom has expired and no appeal has been perfected);
provided, however, that the Date of Termination shall be extended for a period
- --------  -------
not to exceed six months by a notice of dispute given by the Executive and then
only if such notice is given in good faith and the Executive pursues the
resolution of such dispute with reasonable diligence and agrees to reimburse
the Company for all compensation received from and after the date of
termination specified in Section 7.2 in the event the dispute is not resolved
in the Executive's favor.

          7.4 Compensation During Dispute. If a purported termination occurs
              ---------------------------
following a Change in Control or potential Change in Control and during the
Term and the Date of Termination is extended in accordance with Section 7.3
hereof, the Company shall continue to pay the Executive the full compensation
in effect when the notice giving rise to the dispute was given (including, but
not limited to, salary) and continue the Executive as a participant in all
compensation, benefit and insurance plans in which the Executive was
participating when the notice giving rise to the dispute was given, until the
Date of Termination, as determined in accordance with Section 7.3 hereof.
Amounts paid under this Section 7.4 are in addition to all other amounts due
under this Agreement (other than those due under Section 5.2 hereof) and shall
not be offset against or reduce any other amounts due under this Agreement,
except that if the notice of dispute is given by the Executive and the term is
extended pursuant to Section 7.3 beyond the date specified in accordance with
Section 7.2 and the Executive does not prevail in his dispute, Executive shall
reimburse to and refund to the Company all compensation paid after the
termination date specified in Section 7.2.

          8.  No Mitigation.  The Company agrees that, if the Executive's
              -------------
employment with Sierra terminates during the Term, the Executive is not
required to seek other employment or to attempt in any way to reduce any
amounts payable to the Executive by the Company pursuant to Section 6 hereof or
Section 7.4 hereof. Further, the amount of any payment or benefit provided for
in this Agreement (other

                                      9



than Section 6.1(B) hereof) shall not be reduced by any compensation earned by
the Executive as the result of employment by another employer, by retirement
benefits, by offset against any amount claimed to be owed by the Executive to
the Company, or otherwise.

          9. Successors; Binding Agreement.
             -----------------------------

          9.1 In addition to any obligations imposed by law upon any successor
to the Company, the Company will require any successor (whether direct or
indirect, by purchase, merger, consolidation or otherwise) to all or
substantially all of the business and/or assets of the Company to expressly
assume and agree to perform this Agreement in the same manner and to the same
extent that the Company would be required to perform it if no such succession
had taken place. Failure of the Company to obtain such assumption and agreement
prior to the effectiveness of any such succession shall be a breach of this
Agreement and shall entitle the Executive to compensation from the Company in
