                          COMMON STOCK INVESTMENT PLAN
    
 
    The  Common Stock Investment  Plan (the "Plan")  of Sierra Pacific Resources
(the "Company")  provides holders  of its  Common Stock,  $1.00 par  value  (the
"Common  Stock"), and other investors with a convenient and economical method of
investing in shares  of the Company's  Common Stock without  payment of  service
charges.
 
    Shares may be purchased through the Plan by:
 
    --    SHAREHOLDERS,  who may  reinvest dividends on  all of  their shares of
          Common Stock  for which  they hold  certificates issued  in their  own
          names;
 
    --    INVESTORS  WHO ARE NOT ALREADY SHAREHOLDERS,  who may join the Plan by
          making an  initial investment  of at  least $50,  up to  a maximum  of
          $100,000  per year, which  will be used to  purchase Common Stock, and
          thereafter have  all  dividends on  shares  purchased under  the  Plan
          automatically reinvested in additional shares of Common Stock; and
 
    --    ALL  PARTICIPANTS,  who may  invest  at their  option  additional cash
          amounts of not less than $50 per payment, up to $100,000 per year, for
          the purchase  of additional  shares  of Common  Stock for  their  Plan
          accounts.
 
    This Prospectus relates to authorized and unissued shares of Common Stock of
the  Company registered for  issuance under the  Plan. The price  of such shares
will be 100% of the average of  the highest and lowest prices for the  Company's
Common  Stock in the  consolidated reporting system  for trades on  the New York
Stock Exchange on the pricing date, which normally will be the same date as  the
dividend payment date or, in any month in which a cash dividend is not paid, the
first  day of such month. Shares may also  be purchased for the Plan on the open
market, in which case the price  will be the average price (including  brokerage
commissions)  paid  for  all  shares purchased  during  the  relevant Investment
Period. See Question 19 under "Description of the Plan."
 
    The  Plan  represents  an  amendment  to  the  Company's  existing  Dividend
Reinvestment and Stock Purchase Plan. SHAREHOLDERS WHO ARE ALREADY PARTICIPATING
IN  THE EXISTING PLAN NEED TAKE NO FURTHER ACTION AT THIS TIME. Shareholders who
do not elect to participate in the Plan will continue to receive cash dividends,
as declared, by check.
 
    The  terms  and  conditions  governing  the  Plan  are  described  in   this
Prospectus,  and it  is suggested  that this  Prospectus be  retained for future
reference.
 
   
    Outstanding shares  of Common  Stock are,  and the  shares of  Common  Stock
offered hereby will be, listed on the New York Stock Exchange. The reported last
sale  price of the Common Stock on the New York Stock Exchange on July   , 1996,
was         .

PURPOSE OF PLAN................................  The primary purpose  is to  provide holders  of

TIMING OF DIVIDEND REINVESTMENT................  The  Company  has  paid dividends  on  or about
                                                 February 1,  May 1,  August 1  and November  1.
                                                 Enrollment in the Plan by the record date for a
                                                 particular  dividend  (usually  about  15  days
                                                 prior to the dividend payment date) will result
                                                 in that  dividend  being reinvested  in  Common
                                                 Stock under the Plan.
 
TIMING OF OPTIONAL INVESTMENTS.................  Optional  and initial cash investments received
                                                 prior to the monthly Investment Date (typically
                                                 the first day of  each month) will be  invested
                                                 that  month. Investments received later will be
                                                 held  in   escrow   until  the   next   monthly
                                                 Investment  Date. Because  no interest  will be
                                                 paid on  optional or  initial cash  investments
                                                 held  in escrow, Participants are encouraged to
                                                 mail such investments so as to arrive as  close
                                                 as  possible  but not  later than  two business
                                                 days before each Investment Date.

                                  THE COMPANY
 
    The  Company  is an  exempt public  utility  holding company.  The principal
subsidiary of  the Company  is  the Power  Company,  a regulated  utility  which
accounted  for 98% of the Company's consolidated assets as of December 31, 1995.
The  Power  Company   is  engaged   primarily  in   the  generation,   purchase,
transmission,  distribution and sale of electric energy to approximately 270,000
customers in a service territory of approximately 50,000 square miles located in
western, central and northeastern Nevada, including the cities of Reno,  Sparks,
Carson  City and Elko, and the Lake  Tahoe area of California. The Power Company
met its electric energy  requirements for the twelve  months ended December  31,
1995  by  utilizing  purchased  power (46%),  coal  generation  (23%),  gas/ oil
generation (30%), and  hydroelectric (1%).  The Power Company  has no  ownership
interest in, nor does it operate, any nuclear generating units and has no future
plans  to  do so.  The  Power Company  also provides  gas  and water  service to
approximately 92,000 gas and  61,000 water customers in  the cities of Reno  and
Sparks and environs.
 
   
    In June, 1994, the Company, the Power Company and The Washington Water Power
Company ("WWP") entered into an Agreement and Plan of Reorganization and Merger,
as  subsequently amended (the "Merger Agreement"), which provides for the merger
of the Company, the Power Company and WWP into Altus Corporation ("Altus").  WWP
is   a  combined  electric  and  gas  utility,  with  headquarters  in  Spokane,
Washington. Although  the proposed  merger  had received  all of  the  necessary
approvals  from the shareholders of  the Company, the Power  Company and WWP and
from six state  utility commissions, the  merger was still  under review by  the
Federal  Energy Regulatory Commission  when, on June 28,  1996, WWP notified the
Company that it had elected to terminate the Merger Agreement in accordance with
its terms. As a  result of the  termination of the  Merger Agreement, the  Power
Company  will continue to  operate as a  separate utility and  as a wholly-owned
subsidiary of the Company.
    
 
    The Company's principal non-utility subsidiaries are: Tuscarora Gas Pipeline
Company, which is a joint venture  partner in a natural gas pipeline  operation;
and  Lands  of Sierra,  Inc., which  is  engaged in  real estate  management and
development. The address  of the  Company is P.O.  Box 30150  (6100 Neil  Road),
Reno, Nevada 89520 (Telephone (702) 689-3600).
 
                            DESCRIPTION OF THE PLAN
 
    This  document constitutes the  Company's Common Stock  Investment Plan (the
"Plan"), and the following  questions and answers contain  all of the terms  and
conditions  of the Plan. For additional information concerning the Plan, you may
telephone the Company at (800) 662-7575.
 
    Various capitalized terms  used in  the Plan  are explained  in the  section
entitled "DEFINITIONS" at the end of the Plan.
 
PURPOSE AND BENEFITS
 
1.  WHAT IS THE PURPOSE OF THE PLAN?
 
    The  Plan  offers  Shareholders  a convenient  method  of  reinvesting their
quarterly cash dividends, and for making optional cash investments, to  purchase
additional shares of the Company's Common Stock. Additionally, investors who are
not already Shareholders may join the Plan by making an initial investment of at
least  $50 which will be  used to purchase shares  of the Company's Common Stock
for their Plan accounts,  and thereafter participate in  the Plan. Common  Stock
purchases  under the Plan may  be made, at the  Company's option, either in open
market or privately negotiated  purchases of Common Stock  or from newly  issued
Common  Stock,  provided that  the Company  may  not change  from one  manner of
purchase to the other more than once in any three (3) month period. In addition,
such a change  may be made  only if the  Board of Directors  or Chief  Financial
Officer determines the Company's need to raise additional capital has changed or
that there is another valid reason for such change, such as action by a state or
federal  regulatory agency  recommending or  requiring a  change in  the capital
structure of the Company  or the Power Company.  When shares are purchased  from
the   Company,  the  Company  will   receive  additional  funds  for  additional
investments in the common equities of its subsidiaries and for general corporate
purposes. See "USE OF PROCEEDS."
 
2.  WHAT ARE THE BENEFITS OF THE PLAN?
 
    The Plan offers Participants the following benefits:
 
    A.  Existing Shareholders
 
                                       5
<PAGE>
        -- Cash dividends  on  shares  of  Common  Stock  for  which  they  hold
           certificates  in their  own name  may be  automatically reinvested in
           additional shares of Common Stock, and  the new shares will be  added
           to their Plan accounts.
 
    B.  Investors who are not Shareholders
 
        -- The  Plan may be joined  by making an initial  investment of at least
           $50.
 
    C.  All Participants
 
        -- Cash dividends on all shares of  Common Stock in their Plan  accounts
           will  be automatically  reinvested to  purchase additional  shares of
           Common Stock for their Plan accounts at the Market Price;
 
        -- Optional cash investments  of at least  $50, and up  to a maximum  of
           $100,000  per year, may be made for the purchase of additional shares
           of Common Stock for their Plan accounts at the Market Price;
 
        -- The cumbersome safekeeping of  certificates for shares purchased  for
           their  account under the Plan can  be avoided, and regular statements
           regarding purchases and other activities for their Plan account  will
           be provided to simplify their own record keeping. See Question 31.
 
PARTICIPATION
 
3.  WHO IS ELIGIBLE TO PARTICIPATE IN THE PLAN?
 
    Any  person who  owns Common  Stock registered  in his  or her  own name (as
opposed to  shares beneficially  owned but  registered in  the name  of  another
party, such as a broker, clearing association, bank or other nominee or trustee)
is  eligible  to participate  in the  Plan. Beneficial  owners of  the Company's
Common Stock whose shares are held for them in registered names other than their
own may participate by having some or all of their shares transferred into their
own name.
 
    In addition, any investor who is not already a Shareholder may join the Plan
by making an  initial investment as  described under Question  4 and  thereafter
participating in the Plan.
 
4.  HOW MAY A PERSON JOIN THE PLAN?
 
    Shareholders  may join the Plan by completing an Authorization Card provided
by the Company and  sending it to Sierra  Pacific Resources, Attention  Manager,
Stockholder  Relations, P.O. Box 30150,  Reno, Nevada 89520. Authorization Cards
may be obtained  by writing  to this  address or by  calling the  office of  the
Manager, Shareholder Relations of the Company at (800) 662-7575.
 
    Investors  who are not already Shareholders  may join the Plan by completing
an Enrollment Form provided by the Company and sending it to the Company at  the
foregoing  address together with an initial cash investment of at least $50. The
maximum investment  which  may  be  made upon  joining  the  Plan  is  $100,000.
Residents  of  Arizona  and  Illinois  who  are  not  already  Shareholders  may
participate in the Plan by  first acquiring one or  more shares of Common  Stock
outside  of  the  Plan and  then  completing  and returning  to  the  Company an
Authorization Card.
 
    Shareholders  who  select  either  of  the  dividend  reinvestment   options
described  under Question 7 below are not  required to send any payment with the
Authorization Card. An optional  cash investment may, however,  be made at  such
time.  See Questions 13  and 14. A  Shareholder who wants  to participate in the
Plan while continuing  to receive full  cash dividends on  all shares of  Common
Stock registered in his or her name may join the Plan by making an optional cash
investment  of at least  $50 and up  to a maximum  of $100,000, at  the time the
original Authorization  Card  is  returned.  All  joint  owners  must  sign  the
Authorization Card.
 
5.  WHEN MAY A PERSON JOIN THE PLAN?
 
    The  Plan may be joined  at any time by  submitting an Authorization Card or
Enrollment Form in the manner described under Question 4 above.
 
    If an Authorization Card from a  Shareholder electing to participate in  the
Plan by having cash dividends reinvested is received by the Company on or before
the  record date for the next dividend (approximately 15 days before the payment
date), then participation in the  Plan will begin on  the date such dividend  is
paid  (in the past,  cash dividends on Common  Stock have been  paid on or about
February 1, May 1, August 1 and November 1) and the dividend will be invested in
additional shares of Common Stock in accordance with the investment instructions
contained in  the  Authorization  Card. See  Questions  9,  10 and  11.  If  the
Authorization Card is received in the
 
                                       6
<PAGE>
period  between any dividend record date and payment date, that dividend will be
paid in cash and the Shareholder's initial dividend reinvestment will be delayed
until the  following dividend.  For  example, if  the  Company declares  a  cash
dividend on its Common Stock payable on August 1, the Authorization Card must be
received  by the Company on or before July  15 in order for the dividend paid on
August 1 to be  reinvested. If the  Authorization Card is  received on or  after
July 16, the dividend paid on August 1 will be sent to the Shareholder as usual,
and such Shareholder's participation in the Plan will begin on the date the next
cash dividend on Common Stock is paid (on or about November 1 in this example).
 
    For  a Shareholder who elects to participate  in the Plan by making optional
cash payments only, participation in the Plan will begin on the first Investment
Date for optional  and initial  cash investments  following the  receipt by  the
Company of the Shareholder's Authorization Card and optional cash payment.
 
    The  initial purchase of Common  Stock for an investor  who is not already a
Shareholder will be made on the  first Investment Date for optional and  initial
cash  investments following the receipt of the investor's Enrollment Form by the
Company. The  next  cash dividend  on  the  shares purchased  with  the  initial
investment  will automatically be fully reinvested to purchase additional shares
of Common Stock  for the  Participant's Plan account  at the  Market Price.  See
Question 7.
 
    See  Questions  13, 14  and  15 for  a  description of  how  a Participant's
optional cash payments may be invested under the Plan.
 
6.  WHAT DOES THE ENROLLMENT FORM PROVIDE?
 
   
    The Enrollment Form  allows investors  who are not  already Shareholders  to
participate in the Plan. By returning an executed Enrollment Form to the Company
with  an initial cash investment  of at least $50, up  to a maximum of $100,000,
the investor directs the Plan administrator to establish a Plan account for  the
investor  and apply the initial  investment to the purchase  of Common Stock for
the investor's Plan account. Shares of Common Stock purchased for the investor's
Plan account  will  not  be registered  in  the  investor's name,  but  will  be
registered  in the name of First Chicago  Trust Company of New York (the "Bank")
or one of its nominees.  See Questions 22, 30 and  38. Residents of Arizona  and
Illinois should follow the procedures described in Question 4.
    
 
    Dividends  on  all  shares  held  in the  investor's  Plan  account  will be
automatically reinvested in additional shares of Common Stock for the investor's
Plan account at the Market Price as  described in Question 19. Once an  investor
becomes  a Participant in the Plan, all provisions, benefits and requirements of
the Plan become  applicable to  the investor. Should  the investor  subsequently
acquire  additional shares which  are registered in  his or her  name exactly as
specified on  the  Enrollment  Form,  the  original  authorization  to  reinvest
dividends  will  include  the new  shares,  unless the  Participant  changes the
investment option selected. If an investor withdraws shares from his or her Plan
account and wishes  to change  the dividend  reinvestment option  in effect  for
those  shares, a separate Authorization Card must  be returned to the Company to
indicate how the investor wishes dividends on such shares to be reinvested under
the Plan. See Questions 7 and 11.
 
7.  WHAT DOES THE AUTHORIZATION CARD PROVIDE?
 
    The Authorization  Card allows  Shareholders to  indicate how  they wish  to
participate  in  the Plan.  By completing  the  appropriate instructions  on the
Authorization Card,  Shareholders may  indicate whether  they want  to  reinvest
their cash dividends under either of the following reinvestment options:
 
         Full  Dividend Reinvestment -- Dividends on  all shares of Common Stock
    registered in  the Shareholder's  name  or held  in the  Shareholder's  Plan
    account  will be automatically paid  to the Bank or  its nominee, which will
    apply such dividends to the purchase of additional shares of Common Stock at
    the Market Price for the Shareholder's Plan account.
 
        Partial  Dividend Reinvestment -- Only the  dividends on shares held  in
    the Participant's Plan account will be automatically applied to the purchase
    of additional shares of Common Stock for the Shareholder's Plan account. The
    Shareholder  will continue to receive cash dividends by check on shares held
    outside the Plan. See Question 11.
 
    A Shareholder who does not want dividends on any of the shares registered in
his or her name to be reinvested under the Plan may nevertheless indicate on the
Authorization Card that the Shareholder wishes to make optional cash investments
as described under Questions  13, 14, 15 and  16, and may join  the Plan in  the
manner  described under Question  4. Such Shareholders  will continue to receive
cash dividends, as declared, on the shares registered in their names by check.
 
                                       7
<PAGE>
    CASH DIVIDENDS ON ALL  SHARES OF COMMON STOCK  HELD UNDER THE PLAN,  WHETHER
PURCHASED  WITH  REINVESTED  DIVIDENDS  OR WITH  OPTIONAL  CASH  INVESTMENTS AND
INCLUDING ANY SHARES TRANSFERRED BY THE  SHAREHOLDER TO HIS OR HER PLAN  ACCOUNT
AS  DESCRIBED  UNDER  QUESTION 31,  WILL  AUTOMATICALLY BE  FULLY  REINVESTED IN
ADDITIONAL SHARES OF COMMON STOCK. If  a Shareholder desires to discontinue  the
automatic  reinvestment of cash dividends on some  portion of the shares held in
his or her Plan account, the Shareholder  may withdraw any whole number of  such
shares  from the Plan and be issued  certificates for those shares registered in
the Shareholder's name. See Questions 22  and 23. Thereafter, cash dividends  on
all  shares held outside the  Plan account will be  paid by check, provided that
the Shareholders' dividend  reinvestment option  then in effect  calls for  such
payment. See Questions 6, 8 and 11.
 
   
    The  Authorization Card directs the  Company to pay the  Bank or its nominee
all cash dividends  on shares of  Common Stock registered  in the  Shareholder's
name  or held in  the Shareholder's Plan  account which are  to be reinvested in
accordance with  the dividend  reinvestment option  selected. The  Authorization
Card  also directs that all  cash dividends received by  the Bank or its nominee
for reinvestment,  together  with any  optional  cash investments  made  by  the
Shareholder,  be used to  purchase shares of Common  Stock for the Shareholder's
Plan account.
    
 
8.  HOW MAY A PARTICIPANT CHANGE OPTIONS UNDER THE PLAN?
 
    A Participant may change investment options previously selected at any  time
by  requesting a  new Authorization  Card and returning  it to  the Company. All
joint owners must sign.  Any change in options  with respect to reinvestment  of
dividends  must be received by the Company on  or before the record date for the
next dividend payment in order  for the change to  be effective with respect  to
such dividend. See Question 5.
 
DIVIDENDS
 
9.  WILL PARTICIPANTS BE CREDITED WITH DIVIDENDS ON SHARES HELD IN THEIR ACCOUNT
    UNDER THE PLAN?
 
    Yes.  The Company pays dividends, as declared,  to the record holders of all
of its Common Stock.  As the record  holder for Participants,  the Bank (or  its
nominee)  will receive dividends  for all Plan  shares held of  record by it. It
will credit such dividends to Participants  on the basis of full and  fractional
shares  held in their  accounts, and will reinvest  such dividends in additional
shares (to the fourth decimal point) at the Market Price.
 
    Shares purchased through optional and  initial cash investments made in  any
month  on or before the record date for the next dividend (approximately 15 days
before the payment date)  will normally be entitled  to any dividend payable  at
the end of that quarter. See Question 15.
 
10.  WHEN WILL DIVIDENDS BE REINVESTED?
 
    Purchases  of Common Stock with reinvested  dividends will typically be made
on the Dividend Payment  Date. That date is  the Investment Date for  reinvested
dividends.  The Common  Stock normally  pays dividends on  the first  day of the
months of February, May, August and November. Shares acquired by the Bank in the
open market or through  privately negotiated transactions  will be purchased  as
soon  as practicable beginning on  the relevant Investment Date  and in no event
later than thirty (30) days after the relevant Investment Date except for delays
which may occur where and to  the extent necessary under any applicable  federal
securities  laws  or  other  government or  stock  exchange  regulations. Shares
representing purchases under  the Plan  of newly  issued Common  Stock may,  for
administrative  purposes, be issued by the Company on  or as of a date up to one
week after the related Investment Dates. See Question 18.
 
11.  WHAT HAPPENS IF A PARTICIPANT WHO IS REINVESTING THE CASH DIVIDENDS ON  ALL
     OR  A PART OF  HIS SHARES OF COMMON  STOCK SELLS OR  TRANSFERS A PORTION OF
     SUCH SHARES? WHAT IF THE PARTICIPANT ACQUIRES ADDITIONAL SHARES IN THE OPEN
     MARKET OR OTHERWISE?
 
   
    If a Participant  who is reinvesting  cash dividends  on all of  his or  her
shares disposes of a portion of such shares, the cash dividends on the remainder
of  the shares will continue to be reinvested. If additional shares are acquired
and are registered in the Participant's name  exactly as it is specified on  his
or  her Authorization  Card or  Enrollment Form,  the original  authorization to
reinvest dividends  on  all shares  will  include  the new  shares,  unless  the
Participant changes the investment option selected.
    
 
    A  Participant may  receive "partial"  dividend reinvestment  by holding the
portion of the  Participant's shares for  which reinvestment is  desired in  the
Plan  and by withdrawing from  the Plan the balance  of the Participant's shares
and  holding  such  shares  in   certificate  form.  By  designating  that   the
Participant's  shares represented by  stock certificates not  be reinvested, the
Participant will receive "partial" reinvestment.  The Plan does not provide  for
partial dividend reinvestment in any other manner.
 
                                       8
<PAGE>
    The  reinvestment options described under Question 7 will continue until the
Participant changes the investment option selected. See Question 8.
 
OPTIONAL CASH PAYMENTS
 
12.  IS A PARTICIPANT OBLIGATED TO MAKE OPTIONAL CASH INVESTMENTS?
 
    No. While  the optional  cash investment  feature offers  an opportunity  to
increase  ownership under favorable  terms, it is intended  to be voluntary only
and a Participant is not required to make such cash investments.
 
13.  HOW DOES THE OPTIONAL CASH INVESTMENT WORK?
 
    A Participant in the Plan may invest a minimum of $50 at any time, and up to
a maximum of $100,000 cash annually, in  shares of Common Stock under the  Plan.
Cash payments received by the Company will be promptly forwarded to a segregated
escrow  account at a bank until it is invested in shares of the Company's Common
Stock, typically  on the  first Investment  Date following  the receipt  of  the
optional  cash payment. Optional cash payments will  be held in escrow until the
next such date, except that upon  the written request of a Participant  received
up  to one  business day  prior to the  Investment Date,  the Participant's cash
payment will be returned. See Question 15.
 
    Cash payments will not be accepted  by the Company if a Participant  imposes
any restrictions with respect to the number of shares to be purchased, the price
at  which shares are  to be purchased, the  timing of the  purchase, or what the
Participant's balance will  be following  a purchase. In  addition, the  Company
cannot purchase shares for a
Participant   without  advance  payment,  nor  can  it  refund  any  part  of  a
Participant's cash payment after  shares are purchased. It  is not possible  for
the  Company to  tell a Participant  in advance how  much money to  send for the
purchase of a full or fractional share  because the price per share will not  be
known at the time an optional cash payment is made.
 
14.  HOW ARE CASH PAYMENTS MADE?
 
    A  cash payment may be made by an  investor who is not already a Shareholder
when enrolling in the Plan  by enclosing a check  with the Enrollment Form.  See
Question  6. For  a Shareholder  electing to participate  in the  Plan by making
optional cash payments  only, a  cash payment must  accompany the  Authorization
Card  in  order  for his  or  her  participation to  commence.  See  Question 4.
Thereafter, an optional  cash investment  may be made  only through  the use  of
stock  purchase forms sent  to Participants by  the Company as  an attachment to
their monthly confirmation statements or quarterly summary statements.
 
    Only one cash payment may be made in each month, and such payment may be  in
any amount not less than $50 nor more than $100,000. A Participant need not make
an  optional cash investment  each month and  is not obligated  to make the same
optional cash investment every time.
 
15.  WHEN WILL OPTIONAL OR INITIAL CASH  INVESTMENTS BE USED TO PURCHASE  COMMON
     STOCK?
 
    Optional  and initial cash investments will  be invested once each month, in
order to reduce  the accumulation of  uninvested funds. Shares  acquired in  the
open  market  or  through  privately negotiated  transactions  using  initial or
optional cash investments will be purchased  by the Bank as soon as  practicable
beginning on the relevant Investment Date and in no event later than thirty (30)
days  after the relevant Investment Date except for delays which may occur where
and to the  extent necessary  under any  applicable federal  securities laws  or
other  government or stock  exchange regulations. In  any month in  which a cash
dividend on  Common Stock  is paid,  the Investment  Date will  be the  Dividend
Payment  Date. In other months, the Investment Date will be the first day of the
month.
 
    As in the case  of shares purchased with  reinvested dividends, the  Company
may for administrative purposes, when purchasing shares from newly issued Common
Stock, issue shares purchased with optional or initial cash investments on or as
of  a date up to  one week after the related  Investment Dates. See Questions 10
and 18.
 
   
    NO INTEREST WILL  BE PAID ON  OPTIONAL OR INITIAL  CASH INVESTMENTS HELD  IN
ESCROW.  THEREFORE,  PARTICIPANTS  ARE  ENCOURAGED TO  MAIL  THEIR  OPTIONAL AND
INITIAL CASH INVESTMENTS SO AS TO REACH  THE COMPANY FOR FORWARDING TO THE  BANK
AS  CLOSE  AS POSSIBLE  TO  BUT NOT  LATER THAN  TWO  BUSINESS DAYS  BEFORE EACH
INVESTMENT DATE.  ALL SUCH  PAYMENTS RECEIVED  BY  THE COMPANY  ON OR  AFTER  AN
INVESTMENT  DATE WILL BE  HELD IN ESCROW AT  A BANK IN  A SEGREGATED ACCOUNT FOR
INVESTMENT IN THE FOLLOWING MONTH.
    
 
16.  WHAT ARE THE LIMITATIONS ON OPTIONAL CASH INVESTMENTS?
 
    Any Participant  may make  optional cash  investments under  the Plan  in  a
minimum amount of $50 per payment, or in whole dollar increments up to a maximum
of    $100,000    in    any    calendar    year.    Such    funds    should   be
 
                                       9
<PAGE>
received by the Company at  least two business days prior  to the date on  which
they  will be invested to ensure adequate  time for processing. See Question 15.
Only checks or money orders made payable to the Company should be remitted.  The
entire amount of such payments will be invested in full and fractional shares of
the  Company's Common Stock to four decimal  places. Any amount received of less
than $50 per payment or in excess of $100,000 per year will be promptly returned
to the Participant. The  total of optional and  initial cash investments  during
any calendar year cannot exceed $100,000.
 
COSTS
 
17.  WHAT COSTS DO PARTICIPANTS PAY?
 
    Participants  will  incur no  brokerage commissions  or service  charges for
purchases of newly issued shares of Common Stock made under the Plan. The  price
of  shares of  Common Stock  purchased under  the Plan  on the  open market will
include a brokerage  commission. See  Questions 18 and  19. All  other costs  of
administration  of  the Plan,  including  costs of  the  Bank, are  paid  by the
Company, except for a  Bank charge, currently  $.06 per share,  for the sale  of
shares by the Bank on termination of a Plan account. See Question 25.
 
PURCHASES
 
18.  WILL THE PLAN PURCHASE SHARES IN THE OPEN MARKET?
 
    All  Common Stock  purchases under  the Plan may  be made,  at the Company's
option, either (a) in open  market purchases of Common  Stock or (b) from  newly
issued Common Stock, provided that the Company may not change from one manner of
purchase to the other more than once in any three (3) month period. In addition,
such  a change  may be made  only if the  Board of Directors  or Chief Financial
Officer of the Company  determines that the Company's  need to raise  additional
capital  has changed or that there is another valid reason for such change, such
as action by a  state or federal regulatory  agency recommending or requiring  a
change in the capital structure of the Company or the Power Company.
 
    Common  Stock purchased under the Plan on  the open market will be purchased
by the Bank. Subject to certain limitations, the Bank has full discretion as  to
all  matters relating to  open market purchases,  including determination of the
number of shares, if any, to be purchased on any day or at any time of day,  the
price  paid for  such shares,  the markets  on which  such shares  are purchased
(including on  any securities  exchange, on  the over-the-counter  market or  in
negotiated  transactions) and the persons  (including other brokers and dealers)
from or through whom such purchases are made.
 
19.  WHAT PRICE WILL PARTICIPANTS PAY FOR SUCH SHARES?
 
    The price at  which shares will  be purchased with  reinvested dividends  or
optional  and initial cash investments will be  100 percent of the Market Price.
The Market Price will be determined as follows:
 
    - in the case of newly issued shares purchased from the Company, the  Market
      Price  will  be  the average  of  the  highest and  lowest  prices  of the
      Company's Common Stock on the New  York Stock Exchange Composite Tape,  as
      published  in  THE WALL  STREET  JOURNAL for  an  Investment Date.  If the
      Exchange is  open on  the Investment  Date but  no trading  occurs in  the
      Company's  Common Stock, the Market  Price will be the  average of the bid
      and asked prices on that date. If the Exchange is closed on any Investment
      Date, the average of  the highest and lowest  prices on the most  recently
      preceding trading date will be used as the Market Price.
 
    - in  the case of shares purchased on the open market, the Market Price will
      be determined by dividing the total cost (including brokerage commissions)
      of all shares purchased with reinvested dividends or optional and  initial
      cash  investments  during the  applicable Investment  Period by  the total
      number of shares purchased during such Investment Period.
 
    Funds (whether dividend payments or optional or initial cash investments) of
any Participant which would have  been invested in newly  issued shares as of  a
date  when the Market Price is less than  the par value of the shares that would
be issuable will be promptly remitted to the Participant.
 
    It should be recognized  that since investment prices  are determined as  of
the  dates specified in Questions  10 and 15, a  Participant loses any advantage
otherwise available  from  being  able  to  select the  timing  of  his  or  her
investment.
 
                                       10
<PAGE>
20.  HOW MANY SHARES WILL BE PURCHASED FOR PARTICIPANTS?
 
    The  number of shares to be purchased  for each Participant depends upon the
amount of dividends payable,  whether full or  partial reinvestment thereof  has
been  selected, the amount of optional or initial cash investments made, and the
Market Price of the Common Stock. The  total amount to be invested will be  used
to  purchase as many full and fractional  shares (to four decimal places) as can
be purchased at the  purchase price determined as  described under Question  19.
Where  dividends  payable  to foreign  Participants  are subject  to  income tax
withholding, only  the  remainder  of  such  dividends  will  be  reinvested  in
additional shares. See Question 40.
 
STATEMENTS/REPORTS
 
21.  WHEN AND HOW WILL PARTICIPANTS BE ADVISED OF THEIR PURCHASE OF STOCK?
 
    As soon as practicable after each purchase for a Participant's Plan account,
a  statement  will be  mailed by  the  Company to  the Participant  advising the
Participant of the investment. Each Participant in the Plan will also be sent  a
statement  of his  or her  account as  soon as  practicable after  each Dividend
Payment Date. THESE STATEMENTS ARE  THE PARTICIPANT'S CONTINUING RECORD OF  COST
INFORMATION AND SHOULD BE RETAINED FOR TAX PURPOSES.
 
    In  addition to  a copy  of this  Prospectus, each  Participant will receive
copies of any amendments or supplements  hereto in which modifications are  made
to the Plan, and copies of the same communications sent to every other holder of
shares  of  Common  Stock,  including the  Company's  quarterly  reports, annual
report, notice of annual meeting and proxy statement, and income tax information
for reporting dividends paid.
 
CERTIFICATES
 
22.  ARE CERTIFICATES ISSUED FOR THE SHARES PURCHASED?
 
    Certificates will be issued by  the Company to the Bank  to be held for  the
Plan  accounts of Participants. The number of shares credited to a Participant's
account under  the Plan  will be  shown on  his or  her quarterly  statement  of
account.  This procedure provides protection  against loss, theft or inadvertent
destruction of stock  certificates and facilitates  the ownership of  fractional
shares by Participants.
 
    Certificates for shares of Common Stock purchased under the Plan will not be
issued,  unless  the Participant  so requests  or  the Participant's  account is
terminated. At any time, certificates for any number of whole shares credited to
the Participant's account under the Plan will be issued upon the written request
of the Participant. This request should  be mailed to Sierra Pacific  Resources,
Attention:  Manager,  Shareholder Relations,  P.O. Box  30150 (6100  Neil Road),
Reno, Nevada  89520. Any  remaining full  shares and  fraction of  a share  will
continue to be credited to the Participant's account.
 
    Shares held by the Bank for the account of a Participant may not be pledged.
A  Participant who wishes to pledge such  shares must request that a certificate
for such shares be issued in his or her name.
 
    Certificates  for  fractional   shares  will   not  be   issued  under   any
circumstances
 
23.  IN WHOSE NAME WILL CERTIFICATES BE ISSUED?
 
    Each  Plan account of a participating  Shareholder will be maintained in the
name in which  shares of  Common Stock  held of  record by  the Shareholder  are
registered.  Each Plan account of a participating  investor who is not already a
Shareholder at the time of enrollment  will be maintained in the name  specified
on the Enrollment Form when Plan participation begins. Consequently, if and when
certificates  for shares held under the  Plan are issued, such certificates will
be issued in those names. Certificates will be issued for whole shares only.
 
TERMINATION OF PARTICIPANT'S ACCOUNT
 
24.  WHEN MAY A PARTICIPANT TERMINATE HIS PLAN ACCOUNT?
 
    A Participant may withdraw from the Plan  at any time by complying with  the
notice  provisions  described  in  Question 25.  Subsequent  to  a Participant's
withdrawal, all cash dividends will be  paid by check to such individual  unless
he  or she  re-enrolls in the  Plan and elects,  by giving proper  notice to the
Company, to reinvest such dividends, which may be done at any time. See Question
27.
 
25.  HOW DOES A PARTICIPANT WITHDRAW FROM THE PLAN?
 
    In order to withdraw from the Plan, a Participant must so notify the Company
in writing. Such notice should be  sent to Sierra Pacific Resources,  Attention:
Manager,  Shareholder Relations, P.O.  Box 30150 (6100  Neil Road), Reno, Nevada
89520. This notification can be made  by providing the information specified  on
the  tear-off portion of  the quarterly statement and  returning that portion of
the statement to the Company. A Participant's withdrawal takes effect when  such
notice  is received by  the Company; provided,  however, that withdrawal notices
received
 
                                       11
<PAGE>
during the 25 day  period prior to  a cash dividend payment  date will not  take
effect  until the day following such dividend  payment date. Upon receipt by the
Company  from  proper  authority   of  notice  of   a  Participant's  death   or
incompetence,  the Company will  treat the Participant  as having withdrawn from
the Plan. When a Participant withdraws from the Plan, or upon termination of the
Plan by  the Company,  certificates for  whole  shares credited  to his  or  her
account  under the Plan will be issued to the withdrawing Participant and a cash
payment will be made  for any fraction  of a share (see  Question 26) within  30
days of receipt of the notice of withdrawal. Alternatively, the Participant may,
if  desired, indicate in the  notice of withdrawal that  all of the shares, both
whole and fractional, credited to his or  her account in the Plan be sold.  Such
sale  will  be  made  on  the  open  market  within  five  business  days  after
notification by the Company to the Bank and will be made through an  independent
fiduciary  institution  which may  be the  Bank.  See Questions  31 and  39. The
proceeds of such sale, less any brokerage commission and any transfer tax,  will
be  sent  to the  Participant.  Upon withdrawal  from  the Plan,  any uninvested
optional cash payments will be returned to the withdrawing Participant.
 
26.  WHAT HAPPENS TO THE FRACTIONAL SHARES WHEN THE PLAN IS TERMINATED, OR  WHEN
     A  PARTICIPANT REQUESTS A CERTIFICATE FOR WHOLE SHARES BUT WISHES TO EITHER
     REMAIN IN THE PLAN OR TERMINATE THE PARTICIPANT'S ACCOUNT UNDER THE PLAN?
 
    As long as a Participant  remains in the Plan  and owns, either directly  or
under his or her Plan account, one full share, any fractional share balance will
continue to be maintained to the credit of the Participant's account.
 
    When  a Participant's account is terminated or if the Company terminates the
Plan, a  cash  adjustment  representing  the fractional  share  will  be  mailed
directly  to the Participant. The cash payment will be made by the Company based
on the Market  Price of  shares of  the Company's Common  Stock at  the time  of
termination.
 
REJOINING THE PLAN
 
27.  WHEN MAY A SHAREHOLDER OR OTHER INVESTOR REJOIN THE PLAN?
 
    Generally, a Shareholder or other investor may again become a Participant at
any  time. However, the  Company reserves the right  to reject any Authorization
Card or Enrollment Form from a previous Participant on the grounds of  excessive
joining  and termination. Such  reservation is intended  to minimize unnecessary
administrative expense  and  to  encourage  use  of  the  Plan  as  a  long-term
investment service.
 
TAX CONSEQUENCES OF PLAN PARTICIPATION
 
28.  WHAT ARE THE FEDERAL INCOME TAX CONSEQUENCES OF PARTICIPATION IN THE PLAN?
 
    Under  current federal  income tax laws,  reinvested cash  dividends will be
taxed as ordinary income to  the extent that the  cash dividend would have  been
ordinary income to such shareholder. A cash dividend would be ordinary income to
the  extent that the dividend is paid out of the Company's earnings and profits,
with any remaining amount treated first as a return of capital to the extent  of
the  Participant's tax basis in the  Company's shares and thereafter, generally,
as capital gain.  Dividend reinvestment does  not relieve a  Participant of  any
income  tax payable  on such  dividends. Assuming,  as is  anticipated, that the
Company will  have sufficient  earnings and  profits in  the year  in which  any
dividend  is paid, a  Participant whose dividends are  reinvested under the Plan
will therefore be treated as having received, as a dividend, an amount equal  to
the fair market value on the Dividend Payment Date of the shares acquired by the
Participant  through such reinvestment. That value will  be based on 100% of the
Market Price for the  Common Stock on  the Dividend Payment  Date (less, in  the
case  of shares acquired through open  market purchases, the amount attributable
to brokerage commissions). The
Participant's year-end statement  will indicate  the total  amount of  dividends
paid  on shares held for the Participant's Plan account. The Company will send a
separate statement  on Form  1099-DIV  reporting dividends  paid on  all  shares
registered in the Participant's name on the books of the Company.
 
    The  tax basis  for Common  Stock purchased  with reinvested  dividends will
equal 100% of the fair market value  on the Dividend Payment Date of the  shares
so  purchased. The tax  basis of shares  purchased with any  initial or optional
cash investment will be the amount of the initial or optional cash investment.
 
    A Participant's holding period for  shares of Common Stock acquired  through
the Plan will begin on the day following the purchase of such shares.
 
    Upon  withdrawal from  or termination  of the  Plan, a  Participant will not
receive any taxable  income upon the  receipt of certificates  for whole  shares
which have previously been credited to the Participant's account under the Plan.
However,  a Participant who receives, upon termination of the Participant's Plan
account, a cash adjustment for a fraction of a share will realize a gain or loss
with respect to such fraction. See Question 26. Gain or loss will generally also
be realized by the Participant when whole shares are sold either pursuant to the
Participant's
 
                                       12
<PAGE>
request upon withdrawal from  the Plan (see Question  25), or when whole  shares
are  sold or exchanged by  the Participant after the  shares have been withdrawn
from the Plan. The amount  of such gain or loss  will be the difference  between
the amount which the Participant receives for the shares or fraction of a share,
and the tax basis thereof.
 
    Participants  are advised to consult their  own tax advisor to determine the
particular federal, state and local  tax consequences of their participation  in
and disposition of shares purchased under the Plan.
 
29.  WHAT ARE THE STATE INCOME TAX CONSEQUENCES OF PARTICIPATION IN THE PLAN?
 
    State  income tax consequences  vary from jurisdiction  to jurisdiction, and
are not necessarily the  same as federal  income tax consequences.  Participants
should consult their own tax advisor concerning state income tax treatment.
 
ADMINISTRATION
 
30.  WHO ADMINISTERS THE PLAN FOR THE PARTICIPANTS?
 
    The  Company administers the Plan for Participants, maintains records, sends
statements of  account  at least  as  often  as quarterly  to  Participants  and
performs  other duties relating to  the Plan. See Question  37. Shares of Common
Stock purchased under the Plan  will be held by the  Bank, as custodian for  the
Participants,  and registered in the name of  such Bank or its nominee. The Bank
also serves as Transfer Agent and  Registrar for the Common Stock. See  Question
38.
 
OTHER INFORMATION
 
31.  WHAT  IS  THE EFFECT  ON A  PARTICIPANT'S PLAN  ACCOUNT IF  THE PARTICIPANT
     TRANSFERS ALL SHARES  REGISTERED IN  HIS OR HER  NAME HELD  OUTSIDE OF  THE
     PARTICIPANT'S PLAN ACCOUNT?
 
    None,  so long as the Participant has at  least one full share in his or her
Plan account. The Company will continue to reinvest the dividends on the  shares
credited  to the  Participant's account  under the  Plan until  notified by such
Participant that he or she wishes to withdraw from the Plan and such  withdrawal
takes  effect (See Questions  24 and 25).  Distribution of cash  with respect to
those accounts  with only  a fractional  share  remaining will  be made  by  the
Company.
 
    A  Participant who  desires to avoid  the responsibility  for safekeeping of
certificates for  shares registered  in his  or her  name, or  to eliminate  the
necessity  of keeping separate records with respect to such shares, may elect to
transfer all  of his  or  her directly-held  shares  to the  Participant's  Plan
account.  Once  transferred  to  the Participant's  Plan  account,  however, all
dividends on all of such shares  will automatically be reinvested in  additional
shares of Common Stock for the Participant's Plan account at the Market Price.
 
    If  a Participant  wishes to dispose  of his  or her entire  interest in the
Company, the Participant must separately arrange with the Company to dispose  of
the Participant's shares held in the Plan as described in Question 25.
 
32.  WHAT  LIMITATIONS ARE IMPOSED ON THE  PARTICIPANT WITH REGARD TO THE ASSETS
     HELD BY THE BANK UNDER THE PLAN?
 
    The Participant  has no  right to  draw checks  or drafts  against his  Plan
account  or to give  instructions to the Bank  in respect to  any shares or cash
held therein except as  expressly provided in this  Plan. Also, the  Participant
cannot  assign the shares held in his or her Plan account as collateral but must
request delivery of a certificate for full shares as provided in Question 22.
 
33.  HOW WILL  THE  STOCK PURCHASE  RIGHTS  ON SHARES  HELD  UNDER THE  PLAN  BE
     HANDLED?
 
    The  Company is  a party  to a  Rights Agreement  pursuant to  which a stock
purchase right was  distributed to each  holder of Common  Stock outstanding  on
October  31, 1989, and one right  has been and will be  issued for each share of
Common Stock issued  thereafter subject to  the terms of  the Rights  Agreement.
Until the rights become exercisable pursuant to the Rights Agreement, the rights
will  be evidenced by the  certificates for the associated  Common Stock, and no
separate certificate  will be  issued to  represent the  rights. For  a  general
description  of the  terms of the  Rights Agreement, see  "DESCRIPTION OF COMMON
STOCK -- Rights Agreement," below.
 
34.  WHAT HAPPENS IF  THE COMPANY ISSUES  A STOCK DIVIDEND  OR DECLARES A  STOCK
     SPLIT?
 
    Any  stock dividends  or split shares  distributed by the  Company on shares
held in  the Plan  will be  credited to  the Participant's  Plan account.  Stock
dividends  or split shares  distributed on shares  held directly by Participants
will be  mailed directly  to them  in the  same manner  as to  Shareholders  not
participating in the Plan.
 
                                       13
<PAGE>
35.  HOW WILL A PARTICIPANT'S PLAN SHARES BE VOTED AT ANNUAL OR SPECIAL MEETINGS
     OF SHAREHOLDERS?
 
    Shares  held in the Plan for a  Participant will be voted as the Participant
directs.
 
    If on the  record date for  a meeting  of shareholders there  are shares  of
Common  Stock  credited  to the  account  of  a Participant  in  the  Plan, such
Participant (whether or not any shares of Common Stock are registered in his  or
her  name) will be sent  the proxy material being sent  to all holders of Common
Stock for that  meeting. If such  Participant returns an  executed proxy in  the
usual  way, it will be voted with respect  to all shares credited to the account
of such Participant (including any fraction) as well as all shares registered in
his or her name; or such Participant may vote all of such shares in person if he
or she attends the meeting.
 
    If no instructions  are indicated on  a properly signed  and returned  proxy
card,  all of the Participant's shares (whether  owned directly or held for such
Participant in the Plan) will be voted as stated on the proxy card. If the proxy
card is  not  returned,  the Participant's  shares  may  be voted  only  if  the
Participant or a duly appointed representative votes in person at the meeting.
 
    If the Bank holds shares purchased on the open market which the Bank has the
power  to  vote and  which have  not  been allocated  to the  Participants' Plan
accounts by the applicable record date for  a meeting, then such shares will  be
voted  by the  Bank on each  matter in the  same proportion as  the other shares
voting by proxy or in person at the meeting have voted on such matter.
 
36.  MAY THE PLAN BE CHANGED OR DISCONTINUED?
 
    The Company reserves the right to  suspend, modify or terminate the Plan  at
any  time. Notice  of any such  suspension, modification or  termination will be
sent to all  Participants. The Company  also reserves the  right to suspend  the
Plan,  without notice, for limited periods of time (not to exceed 90 days in any
case) during or  in anticipation  of public  offerings of  the Company's  Common
Stock,  or pending the  filing by the  Company with the  Securities and Exchange
Commission of any report or statement pursuant to Section 13, 14 or 15(d) of the
Securities Exchange  Act  of 1934,  or  pending  any proposed  amendment  of  or
supplement  to this  Prospectus or to  the Registration Statement  of which this
Prospectus is a part, or which may be deemed advisable for any other reason.  If
any  such suspension continues for  longer than 15 days,  the Bank will promptly
return any moneys  received from Participants  but not applied  and will  advise
Participants when such suspension is terminated.
 
    Upon  discontinuance  of the  Plan by  the  Company, certificates  for whole
shares held in a Participant's account under the Plan will be issued and a  cash
payment will be made for any fractional share.
 
37.  WHAT IS THE RESPONSIBILITY OF THE COMPANY UNDER THE PLAN?
 
    The  Company  administers  the  Plan  itself,  receives  all  optional  cash
investments from Plan Participants and forwards  them promptly for deposit in  a
segregated  escrow account at a federally-insured bank where they are held until
investment. The Company also maintains continuing records of each  Participant's
Plan  account, advises Participants as to all  transactions in and the status of
their Plan accounts, and reconciles its records  on a daily basis with those  of
the  Company's Transfer  Agent (the  Bank). Stock  certificates received  by the
Company from Participants for safekeeping under the Plan are promptly  forwarded
to the Transfer Agent for transfer on its records to the nominee account for the
Plan.  The  Company  has  performed  these  administrative  functions  under its
Dividend Reinvestment and  Stock Purchase  Plan (the predecessor  to this  Plan)
and,  as a result, is registered as a  transfer agent under the Exchange Act and
is subject to periodic examination by the Commission.
 
    ALL NOTICES FROM THE  COMPANY TO THE PARTICIPANTS  WILL BE ADDRESSED TO  THE
PARTICIPANT  AT  HIS  OR  HER  LAST ADDRESS  OF  RECORD  WITH  THE  COMPANY. THE
PARTICIPANT SHOULD  NOTIFY THE  COMPANY PROMPTLY  IN WRITING  OF ANY  CHANGE  OF
ADDRESS.
 
    The  Company or its agent  in administering the Plan  will not be liable for
any act done  in good  faith or  for any good  faith failure  to act,  including
without  limitation any claim or liability arising out of failure to terminate a
Participant's account upon such Participant's  death prior to receipt of  notice
in  writing of such death. The foregoing limitation does not apply to violations
of the federal securities laws.
 
    The Participant should recognize that the Company cannot guarantee a  profit
or protect against a loss on the shares purchased under the Plan.
 
                                       14
<PAGE>
38.  WHAT  IS THE RESPONSIBILITY OF THE BANK AS AGENT FOR PARTICIPANTS UNDER THE
     PLAN?
 
    The Bank  holds in  a nominee  name all  shares purchased  for  Participants
through  their Plan  account. In addition,  when open market  purchases are made
under the Plan, the  Bank receives the Participant's  dividends which are to  be
reinvested  and all optional  cash investments from the  escrow account in which
they are  held and  invests such  funds in  additional shares  of the  Company's
Common Stock for the Participant's Plan account.
 
    In performing its duties under the Plan, the Bank will not be liable for any
act  done  in good  faith, or  for any  good faith  omission to  act, including,
without limitation, any claims of liability arising out of failure to  terminate
a Participant's account upon such Participant's death prior to receipt of notice
in writing of such death.
 
39.  WHO  BEARS THE  RISK OF MARKET  PRICE FLUCTUATIONS IN  THE COMPANY'S COMMON
     STOCK?
 
    A Participant's investment in shares held in  his or her Plan account is  no
different  than  an  investment  in directly-held  shares  in  this  regard. The
Participant bears the risk of  loss and the benefits  of gain from market  price
changes with respect to all of the Participant's shares.
 
    Participants  selling their  shares should  be aware  that the  Common Stock
price may fall during the period between a request for sale, its receipt by  the
Company,  and the ultimate sale in the open market by the Bank. This risk should
be evaluated  by the  Participant, and  is  a risk  to be  borne solely  by  the
Participant.
 
    Neither  the Company nor the Bank  can guarantee that shares purchased under
the Plan will, at any particular time, be worth more or less than their purchase
price.
 
40.  WHAT PROVISION IS MADE FOR FOREIGN SHAREHOLDERS WHOSE DIVIDENDS ARE SUBJECT
     TO INCOME TAX WITHHOLDING?
 
    In the case of participating foreign holders of Common Stock whose dividends
are subject to United States income  tax withholding, the Company will apply  an
amount  equal to the dividends to be reinvested, less the amount of tax required
to be  withheld,  to the  purchase  of shares  of  Common Stock.  The  quarterly
statements confirming purchases made for such foreign Participants will indicate
the amount of tax withheld.
 
    Optional  cash payments received from foreign Shareholders must be in United
States dollars and will be  invested in the same  manner as payments from  other
Participants.
 
41.  WHAT HAS BEEN THE LEVEL OF PARTICIPATION IN THE PLAN?
 
    As  of December 31, 1995,  12,135 holders of the  Company's Common Stock, or
approximately 48% of all common Shareholders, were Participants in the Company's
Dividend Reinvestment and Stock Purchase Plan, the prior version of this Plan.

      York  Stock  Exchange  Composite Tape,  as  published in  THE  WALL STREET
      JOURNAL for an Investment Date. If the Exchange is open on the  Investment
      Date but no trading occurs in the Company's Common Stock, the Market Price
      will  be the  average of  the bid and  asked prices  on that  date. If the
      Exchange is closed on any Investment Date, the average of the highest  and
      lowest  prices on the most recently preceding trading date will be used as
      the Market Price.
 
    - in the case of shares purchased on the open market, the Market Price  will
      be determined by dividing the total cost (including brokerage commissions)
      of  all shares purchased with reinvested dividends or optional and initial
      cash investments  during the  applicable Investment  Period by  the  total
      number of shares purchased during such Investment Period.
 
    "PARTICIPANT"  means any Shareholder  or other investor  who has returned an
Authorization Card or an Enrollment Form  to the Company indicating election  to
participate  in the  Plan, and  who has been  duly enrolled  in the  Plan by the
Company.
 
    "PLAN" means the Common Stock Investment Plan of the Company.
 
    "SHAREHOLDER" means  any HOLDER  OF RECORD  of the  Company's Common  Stock.
Shares  are held "of record"  by a Participant only  when the Participant's name
appears on the stock certificate, indicating  that the shares are registered  in
the Participant's name in the Company's records for its Common Stock.
 
                                USE OF PROCEEDS
 
    The  net proceeds  from the sale  by the  Company of shares  of Common Stock
pursuant to the Plan will be used  to make additional investments in the  common
equities  of the  subsidiaries of  the Company  and for  other general corporate
purposes. The amounts of  additional investments in the  common equities of  the
subsidiaries  will depend upon various  factors, including their future earnings
and construction programs. The subsidiaries propose to use the funds received to
fund  construction,  to  reduce  certain  indebtedness  and  for  other  general
corporate  purposes. The Company is  unable to estimate the  number of shares of
its common Stock that ultimately will be sold pursuant to the Plan or the prices
at which such shares will be sold.
 
                     COMMON STOCK DIVIDENDS AND PRICE RANGE
 
    Prior to the creation  of the holding company  structure in 1984, the  Power
Company  paid  cash dividends  on its  Common  Stock every  year since  1916 and
quarterly dividends every year since 1946. Since 1984, the Company has continued
paying quarterly  dividends every  year. The  Company generally  pays  quarterly
dividends  on the  first day  of February, May,  August and  November. While the
Board of  Directors  intends  to  continue  the  practice  of  paying  dividends
quarterly,  the  amounts and  dates  of future  dividends  will depend  upon the
Company's earnings, financial condition and other factors.

    The Company's primary source  of funds for the  payment of dividends to  its
stockholders  is  dividends paid  by Sierra  Pacific  Power Company  (the "Power
Company")  on  its  Common  Stock,  all  of  which  is  owned  by  the  Company.
Accordingly,  the  Company's  ability to  pay  dividends is  dependent  upon the
ability of the Power Company to pay dividends on its Common Stock. The  Articles
of Incorporation of the Power Company and the indentures relating to the various
series  of its First  Mortgage Bonds contain  restrictions as to  the payment of
dividends on  its Common  Stock and  as to  the purchase  or retirement  of  its
capital stock. Under the most restrictive of these provisions, approximately $69
million  of the Power Company's retained  earnings was available at December 31,
1995 for the payment of cash dividends to the Company. As of December 31,  1995,
the  Company  had consolidated  retained earnings  of approximately  $81 million
available for the payment of cash dividends on the Company's Common Stock.
 
    The Company's senior note purchase agreement also contains a provision which
limits the amount of  dividends or certain other  payments to stockholders  that
may  be made by the Company in the event that the Power Company's securities are
rated lower  than  BBB by  Standard  & Poor's  Corporation  or Baa2  by  Moody's
Investors  Services, Inc.  Under such  circumstances, the  sum of  dividends and
other payments to stockholders  declared, made or obligated  by the Company  for
the period subsequent to December 31, 1992 may not exceed 100% (or minus 100% in
case  of a  net loss) of  the Power  Company's net income  after preferred stock
dividends accumulated after December 31,  1992. These provisions would not  have
restricted  the payment of dividends declared  by the Company in recent periods,
and the  Company does  not  believe that  they will  limit  its ability  to  pay
dividends in the foreseeable future.
 
                          DESCRIPTION OF COMMON STOCK
 
    The authorized capital stock of the Company consists of 90,000,000 shares of
Common  Stock, $1.00  par value  per share.  The following  statements summarize
certain relevant provisions of, and are qualified in their entirety by reference
to, the Company's Articles of Incorporation and the laws of the State of Nevada.
 
COMMON STOCK
 
    All shares of Common Stock participate equally with respect to dividends and
rank equally upon  liquidation. Each share  of Common Stock  is entitled to  one
vote  per  share  at all  meetings  of  shareholders. The  Common  Stock  has no
preemptive rights and does not have cumulative voting rights.
 
    The Board of Directors is classified,  consisting of three classes of  equal
(or nearly equal) membership serving staggered three-year terms. The vote of the
holders  of two-thirds of the  issued and outstanding shares  of Common Stock is
required to  remove  a  director  or  directors from  office  or  to  amend  the
provisions  of the Articles of Incorporation relating to election and removal of
directors, unless, in the case of such an amendment, two-thirds of the Board  of
Directors  approves such amendment, in which case the approval of the holders of
a majority of the outstanding Common Stock is required.
 
                                       17
<PAGE>
    The vote of the holders of  two-thirds of the issued and outstanding  shares
of  Common Stock, in addition to any class  vote required by law, is required to
effect certain mergers, sales of assets or stock issuances involving the Company
and any holder of more than 10 percent of the Common Stock, unless certain "fair
price" criteria and procedural requirements are satisfied or the transaction  is
approved  by a majority of the directors (excluding any director affiliated with
such 10  percent stockholder).  The vote  of the  holders of  two-thirds of  the
issued  and outstanding shares of Common Stock  is required to amend these "fair
price" provisions.
 
    Except  as  described  above,  the   Company  may  amend  its  Articles   of
Incorporation  upon the  affirmative vote  of the holders  of a  majority of the
issued and outstanding shares of Common Stock.
 
    In the event of any liquidation,  dissolution or winding-up of the  Company,
the  holders of  Common Stock are  entitled to  receive pro rata  the assets and
funds of  the Company  remaining  after satisfaction  of  all creditors  of  the
Company.
 
    The Company's transfer agent and registrar is First Chicago Trust Company of
New York.
 
RIGHTS AGREEMENT
 
    The  Company  is a  party  to a  Rights  Agreement (the  "Rights Agreement")
designed to  deter  partial  and  two-tier  tender  offers,  stock  accumulation
programs  and other coercive tactics which might  be used to gain control of the
Company without giving the  Board of Directors the  opportunity to negotiate  on
behalf  of the  Company's stockholders.  Under the  Rights Agreement,  one stock
purchase right  (a "Right")  was distributed  to the  holders of  each share  of
Common Stock outstanding on October 31, 1989, and one Right has been and will be
issued   for  each  share  of  Common  Stock  issued  thereafter  prior  to  the
Distribution Date,  as defined  below.  Each Right  entitles the  holder,  under
certain circumstances, to purchase from the Company one share of Common Stock at
a purchase price of $70.00 per share, subject to adjustment as described below.
 
    Prior  to  the  Distribution Date,  as  defined  below, the  Rights  will be
evidenced by the certificates for the  associated Common Stock, and no  separate
Right  certificates will  be issued.  The Rights  are not  exercisable until the
Distribution Date  and will  expire on  October 31,  1999, unless  exercised  in
connection  with a  transaction of  the type  described below  or unless earlier
exchanged or redeemed by  the Company in the  manner described below.  Following
the  Distribution Date, the  Rights will trade separately  from the Common Stock
and will  be  evidenced  by  separate  Right  certificates.  Until  a  Right  is
exercised,  the holder thereof, as such, will have no rights as a stockholder of
the Company, including, without limitation, the right to receive dividends.
 
    The Distribution Date will occur upon the earlier of (i) 10 days following a
public announcement that a person or  group of affiliated or associated  persons
other  than the Company and its affiliates (an "Acquiring Person") has acquired,
or obtained the right to acquire, beneficial ownership of 15 percent or more  of
the  outstanding Common Stock, or (ii) 10 business days (or such later date as a
majority of  the  Company's Board  of  Directors may  determine)  following  the
commencement  of (or a public announcement of  an intention to make) a tender or
exchange offer if, upon the consummation thereof, the Acquiring Person would  be
the  beneficial owner of 15 percent or more of the outstanding Common Stock. The
proposed merger of the Company, the Power Company and The Washington Water Power
Company with and into Altus Corporation will  not result in the occurrence of  a
Distribution Date under the Rights Agreement.
 
    In  the event that, at any time following the Distribution Date, the Company
is acquired in a merger or other business combination transaction or 50  percent
or  more of its  assets or earning power  are sold, each holder  of a Right will
have the right to receive, upon exercise  at the then current exercise price  of
the  Right, Common Stock  of the acquiring  or surviving company  having a value
equal to two times the exercise price of the Right. In the event that any person
(other than the Company and its  affiliates) becomes the beneficial owner of  15
percent  or more of the then outstanding shares of Common Stock (except pursuant
to a tender or exchange  offer for all outstanding shares  of Common Stock at  a
price  and on terms which a majority of  the Board of Directors determines to be
fair on the basis of criteria set forth in the Rights Agreement) each holder  of
a  Right  will have  the right  to receive,  upon exercise  at the  then current
exercise price of the Right, Common  Stock (or, in certain circumstances,  cash,
property  or other securities of the Company)  having a value equal to two times
the exercise price of the Right. Upon the occurrence of any of the  transactions
referred  to  in  this  paragraph,  any  Rights  that  are,  or  (under  certain
circumstances specified in the Rights Agreement) were, beneficially owned by any
Acquiring Person will immediately become void.
 
                                       18
<PAGE>
    The purchase price  payable, and  the number of  shares of  Common Stock  or
other securities or property issuable, upon exercise of the Rights is subject to
certain antidilution adjustments, as specified in the Rights Agreement.
 
    At  any  time after  the acquisition  by an  Acquiring Person  of beneficial
ownership of 15 percent or more of the outstanding Common Stock and prior to the
acquisition by such Acquiring  Person of 50 percent  or more of the  outstanding
Common  Stock, the  Board of  Directors of the  Company may  exchange the Rights
(other than Rights owned  by such Acquiring Person  which have become void),  in
whole  or in part, at an  exchange ratio of one share  of Common Stock per Right
(subject to adjustment). At any time prior to 10 days following the  acquisition
by  an Acquiring  Person of beneficial  ownership of  15 percent or  more of the
outstanding Common Stock, the Company may redeem the Rights in whole, but not in
part, at a price of $.01 per Right. Immediately upon the action of the Board  of
Directors  of the  Company ordering  redemption of  the Rights,  the Rights will
terminate and the only  right of the  holders of Rights will  be to receive  the
redemption price.

shareholder's equity and cash flows  for each of the  three years in the  period

    Any financial statements and  schedules hereafter incorporated by  reference

    The  statements  of law  and legal  conclusions  made under  "Description of

                             ADDITIONAL INFORMATION
    
 
   
    With respect to the unaudited  interim financial information of the  Company
and  the Power  Company for  the period  ended March  31, 1996,  incorporated by
reference in this  prospectus, the  independent accountants  have reported  that
they  have applied limited procedures  in accordance with professional standards
for a  review  of such  information.  However,  their reports  included  in  the
Company's quarterly report on Form 10-Q and the Power Company's quarterly report
on  Form 10-Q for the quarterly period  ended March 31. 1996 and incorporated by
reference herein, state  that they  did not  audit and  they do  not express  an
opinion  on  that  interim  financial information.  Accordingly,  the  degree of
reliance on their report  on such information should  be restricted in light  of
the  limited nature  of the review  procedures applied. The  accountants are not
subject to the liability provisions of Section  11 of the Act for their  reports
on  the unaudited  interim financial information  because those  reports are not
"reports" or "parts" of the registration statement prepared or certified by  the
accountants within the meaning of Sections 7 and 11 of the Act.
