                               GENERAL INFORMATION

     This proxy  statement  contains  information  regarding the Company's  2003
Annual Meeting of shareholders to be held at the Herberger  Theater Center,  222
East Monroe,  Phoenix,  Arizona at 10:30 a.m. on  Wednesday,  May 21, 2003.  The
enclosed proxy is being solicited by the Company's Board of Directors.

WHAT IS THE PURPOSE OF THE ANNUAL MEETING?

     At the Annual  Meeting you will vote on the matters  outlined in the notice
of meeting on the cover page of this proxy statement.

WHO IS ENTITLED TO VOTE?

     All  shareholders  at the close of  business  on March 21, 2003 (the record
date) are entitled to vote at the meeting.  Each holder of  outstanding  Company
common stock is entitled to one vote per share held as of the record date on all
matters on which  shareholders are entitled to vote,  except for the election of
directors,  in which case "cumulative"  voting applies (see "What is required to
approve the items to be voted on?" on page 2 of this proxy statement).  At close
of  business  on the record date there were  91,257,883  shares of common  stock
outstanding.

HOW DO I VOTE?

     You may vote in person or by a validly designated proxy, or, if you or your
proxy will not be attending the meeting, you may vote in one of three ways:

     VOTE BY INTERNET. The web site address for internet voting is on your proxy
     card. Internet voting is available 24 hours a day; or

     VOTE BY  TELEPHONE.  The toll-free  number for telephone  voting is on your
     proxy card. Telephone voting is available 24 hours a day; or

     VOTE BY MAIL. Mark, date, sign and mail promptly the enclosed proxy card (a
     postage-paid envelope is provided for mailing in the United States).

     If you vote by telephone or internet, DO NOT mail your proxy card.

IS MY VOTE CONFIDENTIAL?

     Yes, your vote is confidential.  Only the following  persons have access to
your  vote:  election  inspectors;  individuals  who help  with  processing  and
counting your votes; and persons who need access for legal reasons.

WHAT CONSTITUTES A QUORUM?

     To carry on the business of the meeting, we must have a quorum. A quorum is
present  when a majority  of the  outstanding  shares as of the record  date are
represented  in  person  or by  proxy.  Shares  owned  by the  Company  are  not
considered  to be present at the  meeting.  Shares that are entitled to vote but
that are not voted at the direction of the beneficial owner (called abstentions)
and votes  withheld by brokers in the absence of  instructions  from  beneficial
owners (called broker  non-votes)

                                       1

will be counted for the purpose of determining whether there is a quorum for the
transaction  of business at the meeting,  but will have no effect on the outcome
of Proposal 2.

WHAT ARE THE BOARD'S RECOMMENDATIONS?

     Unless you give other  instructions  through  your proxy vote,  the persons
named as proxy  holders  on the  proxy  card will  vote in  accordance  with the
recommendations  of the Board of Directors.  The Board's  recommendation  is set
forth  together with the  description  of each item in the proxy  statement.  In
summary, the Board recommends a vote:

     *    FOR election of the nominated slate of directors (see Proposal 1); and
     *    AGAINST approval of the shareholder proposal (see Proposal 2).

     With  respect to any other matter that  properly  comes before the meeting,
the proxy holders will vote as  recommended  by the Board of Directors or, if no
recommendation is given, their own discretion.

WHAT IS REQUIRED TO APPROVE THE ITEMS TO BE VOTED ON?

     ELECTION OF DIRECTORS.  Individuals  receiving the highest  number of votes
     will be  elected.  The  number  of votes  which a  shareholder  may cast is
     calculated by multiplying the number of shares of common stock owned by the
     shareholder as of the record date by the number of directors to be elected.
     Any shareholder may cumulate his or her votes by casting them all in person
     or by proxy for any one nominee,  or by distributing them among two or more
     nominees.  Abstentions  and broker  non-votes will not be counted towards a
     nominee's total.

     OTHER ITEMS. For each other item, the affirmative vote of a majority of the
     shares voted on that item will be required for  approval.  Abstentions  and
     broker  non-votes  on a proposal  will have no effect on the outcome of the
     proposal.

WILL SHAREHOLDERS BE ASKED TO VOTE ON ANY OTHER MATTERS?

     The  Board of  Directors  is not aware of any  other  matters  that will be
brought before the  shareholders  for a vote. If any other matters properly come
before the meeting,  the proxy  holders will vote on those matters in accordance
with the  recommendations  of the Board of Directors,  or, if no recommendations
are given,  in accordance  with their own judgment.  Shareholders  attending the
meeting may directly vote on those matters or they may vote by proxy.

WHO IS ENTITLED TO ATTEND THE ANNUAL MEETING?

     You or your validly  designated  proxy may attend the meeting if you were a
shareholder as of the record date; however, the Board of Directors may limit the
number of proxy  representatives if a shareholder sends several  representatives
to the meeting.

CAN I CHANGE MY VOTE AFTER I SUBMIT MY PROXY?

     Even after you have  submitted  your proxy  card or voted by  telephone  or
online,  you may change your vote at any time before the proxy is  exercised  by
filing with our  Secretary  either a notice of revocation or a signed proxy card
bearing a later date.  The powers of the proxy  holders will be

                                       2

suspended with respect to your shares if you attend the meeting in person and so
request,  although  attendance  at the  meeting  will  not by  itself  revoke  a
previously granted proxy.


                       PROPOSAL 1 - ELECTION OF DIRECTORS

WHO WILL BE ELECTED AT THE ANNUAL MEETING?

     The  Company's  Articles of  Incorporation  provide for the division of the
Board of  Directors  into three  classes of  approximately  equal size (Class I,
Class  II,  and Class  III).  Each  class  serves  for a period of three  years,
although  occasionally a director may be elected for a shorter term in one class
in order to keep the number of directors in each class approximately equal.

     The shareholders will elect four (4) Class III directors this year to serve
as members  of the Board  until the Annual  Meeting of  shareholders  in 2006 or
until their successors are elected and qualified. If one or more of the four (4)
nominees  becomes  unavailable  to serve prior to the meeting date,  the persons
named as proxy  holders  will vote those  shares for the  election of such other
person(s)  as the Board may  recommend,  unless the Board  reduces the number of
directors in the affected class.

     The first table identifies the Class III director nominees, followed by two
tables identifying  continuing directors.  Nominees furnished the information as
of March 21, 2003. The term "APS" refers to Arizona Public Service Company,  and
the term  "PWEC"  refers to  Pinnacle  West Energy  Corporation,  the  Company's
principal subsidiaries.

WHICH DIRECTORS ALSO SERVE ON THE BOARD OF A SUBSIDIARY?

     The following  Company  directors also serve as directors for the following
Company subsidiaries:

Arizona Public Service Company:  Messrs.  Basha,  Davis,  Gallagher,  Herberger,
Jamieson, Lopez, Matlock, Nordstrom and Post, and Mmes. Grant, Hesse and Munro

for election or  appointment  as officers;  and  recommend to the full Board the
form and  amount  of  director  compensation.  Members  of the  Human  Resources
Committee  are  independent  as  defined  in the  NYSE  Proposed  Rules  and the
Company's Director Independence Standards.

WHAT ARE THE RESPONSIBILITIES OF THE CORPORATE GOVERNANCE COMMITTEE?

     The Corporate  Governance  Committee is responsible for developing policies
and practices relating to corporate governance, including the development of the
Company's  Corporate  Governance  Guidelines,  which are  attached to this proxy
statement  as APPENDIX  B.  Additional  functions  of the  Corporate  Governance
Committee include the identification of individuals  qualified to become members
of the Board of Directors and to recommend  director nominees to the full Board.
Any shareholder  wishing to propose a nominee should submit a recommendation  in
writing to the Company's  Corporate  Secretary in accordance with the applicable
provisions of the Company's  Articles of Incorporation and Bylaws. The Corporate
Secretary must receive the nomination no later than November 21, 2003. Copies of
the Company's  Articles of  Incorporation  and Bylaws are available upon written
request of the Corporate Secretary.

     The  Corporate  Governance  Committee  consists  of all  of  the  Company's
non-management  directors,  each of whom is independent  under the NYSE Proposed
Rules and the Company's Director Independence Standards. The NYSE Proposed Rules
require  that  non-management  directors  meet at regularly  scheduled  sessions
without  management.  The  Company  voluntarily  elected to comply with the NYSE
Proposed  Rules.  The  Corporate  Governance  Committee met once in 2002 without
management  present.  In  addition,  non-management  members  of  the  Board  of
Directors also met two (2) times in 2002.

WHAT ARE THE RESPONSIBILITIES OF THE FINANCE AND OPERATING COMMITTEE?

     The  responsibilities  of  the  Finance  and  Operating  Committee  include
reviewing  the Company's  historical  and projected  financial  performance  and
maintaining an awareness of issues affecting the Company's financial  condition;
and reviewing and  recommending  Board action on Company  construction  budgets,
financing  plans,  investment  strategies  relating to Company benefit plans and
nuclear  decommissioning  funds. The Finance and Operating  Committee held seven
(7) meetings in 2002.

WHO IS THE BOARD'S PRESIDING DIRECTOR?

     In September 2002, the Board created a new position of presiding  director,
whose  responsibility is to preside over the periodic  executive sessions of the
Board of Directors in which management directors and other members of management
do  not   participate.   The   presiding   director  also  oversees  the  annual
self-assessment  process of the Board of  Directors  and Board  Committees.

                                       10

The non-management  members of the Board of Directors have designated Michael L.
Gallagher to serve in this position.  Shareholders and other interested  parties
interested in  communicating  directly  with the presiding  director or with the
non-management  directors as a group may do so in writing to Presiding Director,
Pinnacle  West Capital  Corporation,  Station  9068,  P.O.  Box 53999,  Phoenix,
Arizona 85072-3999.

HOW ARE DIRECTORS COMPENSATED?

     Only  non-employee  (outside)  directors are compensated for Board service.
Directors  receive  $24,000 in annual  retainer  fees and they are  eligible for
grants of stock and non-qualified  options under a non-employee  director equity
plan.  Under the plan, a director  receives 900 shares of stock each year. On or
before  December 31 of a director's  first year on the Board,  the director must
own or acquire at least 900 shares of common  stock as a condition  to receiving
the 900-share grant. This ownership requirement increases by 900 shares annually
until it reaches 4,500 shares.  Grants of non-qualified options to directors are
discretionary. To date, no such option grants have been made under the plan.

     Directors are paid $900 for each Board  meeting  attended and $700 for each
committee meeting attended. Company directors who also serve as directors of the
APS and PWEC Boards do so for no additional compensation.  Company directors who
serve on the  SunCor  Board or the El  Dorado  Board  receive  $5,000  in annual
retainer fees and $500 for each Board meeting  attended.  Company  directors who
serve on the NAC Board receive $6,000 in annual  retainer fees and $500 for each
Board  meeting  attended.  As noted above,  Messrs.  Gallagher and Lopez and Ms.
Grant serve as  directors  of SunCor,  Messrs.  Gallagher  and Matlock  serve as
directors  of El  Dorado,  and Mr.  Matlock  serves  as a  director  of NAC.  In
addition,  one director (currently Mr. Matlock) serves as the Board's liaison to
the APS nuclear  oversight  group,  for which the director  receives  $5,000 per
quarter in additional director's fees.

DO WE HAVE INDEPENDENT DIRECTORS?

     The NYSE has proposed  amendments to the NYSE Listed  Company Manual Rules,
which if adopted,  will require  companies listed on the NYSE to have a majority
of independent directors. The NYSE Proposed Rules describe certain relationships
that prevent a director from being  independent and require a company's board of
directors   to  make   director   independence   determinations   in  all  other
circumstances.  The  Company  has  voluntarily  elected to comply  with the NYSE
director  independence  requirements  in  advance  of the  adoption  of the NYSE
Proposed Rules. In March 2003, the Company's Board of Directors adopted Director
Independence Standards to assist it in determining each director's independence.
These Director  Independence  Standards are attached to this proxy  statement as
APPENDIX C. The Board  recognizes  that the final rules  ultimately  adopted may
require modification to the Director  Independence  Standards or ratification or
reevaluation of director independence determinations.

     In accordance  with the NYSE Proposed  Rules and the Director  Independence
Standards,  the Board of Directors has determined that ten (10) of the Company's
thirteen (13) directors are independent.  The ten (10) independent directors are
Messrs. Basha, Gallagher,  Herberger, Jamieson, Lopez, Matlock and Nordstrom and
Mmes.  Grant,  Hesse  and  Munro.  Messrs.  Davis,  Stewart  and  Post  are  not
independent because of their employment with the Company.

                                       11

IS THERE A MANDATORY RETIREMENT AGE FOR DIRECTORS?

     Yes.  Section 3.02 of the Company's  Bylaws provides that a person will not
qualify for election as a director,  whether initially or on re-election,  or by
appointment, if such person's 70th birthday occurs on or has occurred before the
date of such election, re-election or appointment.

                                  AUDIT MATTERS

REPORT OF THE AUDIT COMMITTEE

     The Audit Committee of the Board of Directors submitted the following audit
report:

     In accordance  with its written  charter  adopted by the Board of Directors
(the "Board"),  the Audit Committee of the Board assists the Board in fulfilling
its  responsibility  for  oversight  of  (1)  the  integrity  of  the  financial
statements of the Company,  (2) the  independent  auditor's  qualifications  and
independence,  (3) the performance of the Company's  internal audit function and
independent  auditors,  and (4) the  compliance  by the  Company  with legal and
regulatory requirements and ethical standards.  The Audit Committee has the sole
responsibility for the appointment,  compensation and oversight of the Company's
independent auditors.  As part of its responsibility  regarding the oversight of
the independent auditors, the Audit Committee has a policy of requiring the lead
audit partner to rotate every five years.  Consistent with  Sarbanes-Oxley,  the
Audit Committee reviewed the Company's June 30, 2002 and September 30, 2002 Form
10-Q  Reports  with  management,  the  Company's  independent  auditor,  and the
Company's  internal  auditors  before such documents were filed with the SEC. As
part of that  review,  the Audit  Committee  reviewed the  Company's  disclosure
controls and procedures and the process by which the Company's  chief  executive
officer and chief  financial  officer  satisfied  their  obligations  to certify
certain aspects of the Company's SEC filings  pursuant to SEC  requirements  and
Sections 302 and 906 of  Sarbanes-Oxley.  During the 2002 fiscal year, the Audit
Committee met seven (7) times.

     In discharging its oversight  responsibility  as to the audit process,  the
Committee  obtained  from  Deloitte  & Touche  LLP,  the  Company's  independent
auditor,  a formal written statement  describing all  relationships  between the
auditor and the Company that might bear on the auditor's independence consistent
with Independence Standards Board Standard No. 1, "Independence Discussions with
Audit  Committees." The Committee  discussed with the auditor any  relationships
that may impact the auditor's  objectivity and independence and satisfied itself
as to the auditor's  independence.  The Audit Committee further  determined that
the other  services  provided to the Company for which the auditor  received the
fees  disclosed  on  page  13 of  this  proxy  statement  were  compatible  with
maintaining the auditor's independence. The Committee also discussed the quality
and adequacy of the Company's  internal controls with the Company's  director of
audit services, management, and the independent auditor.

     The  Committee  discussed  and  reviewed  with  Deloitte  & Touche  LLP all
communications  required by generally  accepted  auditing  standards,  including
those  described  in  Statement  on  Auditing  Standards  No.  61,  as  amended,
"Communication  with Audit Committees" and, with and without management present,
discussed and reviewed the results of the independent  auditor's  examination of
the financial  statements.  The Committee also discussed the results of internal
audit examinations.

     The Audit Committee discussed and reviewed the audited financial statements
of the Company as of and for the fiscal year ended  December 31, 2002,  with the
Company's  management,

                                       12

director  of  audit  services  and  the  independent   auditor.   Management  is
responsible  for  the  Company's  financial  reporting  process,  including  the
Company's system of internal  controls,  and for the preparation of consolidated
financial   statements  in  accordance   with  generally   accepted   accounting
principles. The independent auditor is responsible for auditing and rendering an
opinion on those  financial  statements.  The Committee's  responsibility  is to
monitor these processes.

     Based on the aforementioned  review and discussions with management and the
independent auditor,  the Committee  recommended to the Board that the Company's
audited financial  statements be included in the Company's Annual Report on Form
10-K for the fiscal year ended December 31, 2002, for filing with the SEC.

     The Audit  Committee has approved the retention of Deloitte & Touche LLP to
serve as independent auditor for the Company for 2003.

WHO ARE THE  COMPANY'S  INDEPENDENT  ACCOUNTANTS  AND WILL THEY BE AT THE ANNUAL
MEETING?

     As noted above,  the Audit Committee has approved the retention of Deloitte
& Touche LLP, independent certified public accountants, to examine the Company's
financial  statements for the year ending December 31, 2003. The Company expects
that  representatives of that firm will be present at the Annual Meeting.  These
representatives  will have an  opportunity to make a statement if they so desire
and will be available to respond to appropriate questions.

WHAT FEES WERE PAID TO OUR INDEPENDENT ACCOUNTANTS IN 2002?

     AUDIT FEES:  The  aggregate  fees billed for Deloitte & Touche LLP services
rendered for the audit of the Company's annual financial  statement for 2002 and
for review of financial statements included in Forms 10-Q were $1,029,900.

     FINANCIAL  INFORMATION  SYSTEMS DESIGN AND IMPLEMENTATION  FEES: Deloitte &
Touche LLP rendered no services or bills for financial  information  systems and
implementation in 2002.

     ALL OTHER  FEES:  The  aggregate  fees  billed  for  Deloitte  & Touche LLP
services  rendered  for all  services  in 2002,  other  than the audit  services

                             EXECUTIVE COMPENSATION

REPORT OF THE HUMAN RESOURCES COMMITTEE

     The Human  Resources  Committee  of the Board of  Directors  submitted  the
following  report on executive  compensation  for the fiscal year ended December
31, 2002:

WHAT ARE THE COMMITTEE'S RESPONSIBILITIES?

     The Human  Resources  Committee of the Board of Directors of Pinnacle  West
Capital Corporation is responsible for compensation  matters regarding executive
officers.  The duties of the Committee include the review of management's  plans
and  programs  for  the  attraction,   retention,  succession,   motivation  and
development of the human resources needed to achieve corporate  objectives.  The
Committee  also reviews and approves  policies on  compensation,  benefits,  and
perquisites,  including incentive  cash-compensation plans, equity participation
or other forms of executive incentives. The Committee annually reviews the goals
and performance of all executive officers of the Company,  including a review of
all  compensation,  benefits,  and  perquisites  for such officers,  in order to
ensure that there is equity in the compensation  practices and general integrity
in conforming to approved plans and policies.

ARE THE MEMBERS OF THE COMMITTEE INDEPENDENT?

     The Board of Directors  has  determined  the members of the  Committee  are
independent   under  the  NYSE  Proposed   Rules  and  the  Company's   Director
Independence  Standards (see APPENDIX C beginning on page 38). To further ensure
the  Committee's  independence,  the Committee has sole  authority to retain and
terminate any consulting firm used to assist in the evaluation of director,  CEO
or senior  executive  compensation,  including  sole  authority  to approve  the
consulting firm's fees and other retention terms.

WHAT ARE THE OBJECTIVES OF THE COMPANY'S COMPENSATION PROGRAM?

     The  objectives  of the  Company's  executive  compensation  program are to
encourage outstanding performance and promote shareholder return by:

     *    aligning the  financial  interests of the  Company's  key leaders with
          those  of the  Company's  shareholders,  on  both a  short-term  and a
          long-term basis;

     *    providing   incentives  for  achieving  and  exceeding  the  Company's
          short-term and long-term objectives; and

     *    attracting,  retaining  and  rewarding  key  leaders  critical  to the
          Company's success by providing competitive total compensation.

WHAT ARE THE COMPONENTS OF THE COMPANY'S COMPENSATION PROGRAM?

     In  late  2001,   the  Committee,   together  with  an  outside   executive
compensation  consultant,  undertook a comprehensive and in-depth  evaluation of
the Company's historical and prospective executive  compensation  policies.  The
consultant  provided  detailed   compensation  analyses  to  the  Committee  for
determining the  competitiveness  of the Company's  compensation  components and
provided  guidance to the Committee in  establishing  an executive  compensation
plan. The consultant

                                       15

provided  numerous  compensation  scenarios and plan design  alternatives to the
Committee to assist the Committee in  determining a  comprehensive  compensation
strategy.  The resulting  compensation  analysis  consisted of a blended  market
comprised of 50% weighted for the utility  labor market and 50% weighted for the
general  industry labor market,  adjusted for the Company's size and taking into
account the specific duties assigned to each executive officer.

     The  Committee  formulated  its views about the  responsibilities,  skills,
expertise and  performance  of all executive  officers,  with input from Messrs.
Post, Davis and Stewart regarding performances other than their own, and applied
these views in conjunction  with  information  provided by the  consultant.  The
Company's  compensation  program consists of three major elements:  base salary,
annual incentives and long-term incentives.

     BASE SALARY.  The Committee  reviews  competitive  salary  information  and
individual  salaries for executive  officers on an annual basis.  In determining
individual salaries,  the Committee considers the scope of job responsibilities,
individual contributions, business performance and current compensation compared
to  market  practices.  Except  with  respect  to Mr.  Post,  who  is  discussed
separately  below,  the base salaries paid to the Company's  executive  officers
during  2002  overall  were  competitive  with the median  salaries  in both the
utility industry and the compensation analysis blended market.

     ANNUAL  INCENTIVES.  The Company has used  incentive  programs  for all its
employees for a number of years. For 2002,  except with respect to Mr. Post, who
is discussed  separately  below, the Committee  established an incentive payment
program for  executive  officers  based upon Company  earnings and business unit
performance  objectives.  For 2002, the incentive opportunities were designed to
pay out total cash  compensation  (base  salary plus  incentive)  at or near the
median of the compensation analysis if performance objectives were achieved.

     The Committee assessed the attainment levels of the performance  objectives
in early 2003. The Committee  recommended  to the Board,  and the Board awarded,
incentive  payments to executive  officers  based  primarily on the  exceptional
operational  performance  of the  Company's  core  business  units.  Examples of
exceptional operational  performance in 2002 include the following:  APS reduced
its retail rates by 1.5%, resulting in an overall reduction of 14.5% since 1994;
APS was rated as the highest  investor  owned  utility in the West for  customer
satisfaction by its residential and mid-sized customers;  APS met the demands of
customer growth,  which growth was three times the national average; APS had its
best service reliability since 1995, in part by substantially  upgrading the APS
transmission  and  distribution  system;  the  Company  added  more  than  1,100
megawatts  of new  generating  capacity on time and under  budget;  and the Palo
Verde Nuclear  Generating  Station achieved a record 30.8 billion kilowatt hours
of output and a 94.4% capacity  factor while  maintaining an outstanding  safety
record.  The  Committee  also took note of the fact that earnings were below the
target primarily due to non-recurring charges,  including charges resulting from
the  Company's  voluntary  workforce  reduction  (which is  expected  to produce
expense  savings of $30 million  before taxes in 2003) and the  cancellation  of
Redhawk Units 3 and 4 (which will  substantially  improve future year cash flows
and reduce the Company's exposure to risk in the merchant industry sector).  The
awards  were  at or  near  25% of the  maximum  incentive  opportunity,  and are
reflected in the bonus column of the Summary Compensation Table on page 20.

     Messrs.  Stewart and Levine also received additional incentive compensation
based upon the achievement of nuclear operational objectives.  This compensation
is included in the bonus column of the Summary Compensation Table on page 20.

                                       16

     LONG-TERM INCENTIVES.  The Committee believes  management's  performance is
ultimately  judged by the  delivery  of returns to  shareholders  in the form of
share price appreciation and dividends over time. To achieve this, the Committee
intends that grants of stock  options,  performance  shares and stock  ownership
incentives,  which  create  a  personal  investment  in the  Company,  serve  as
significant  components of the total  compensation  package for officers and key
management employees of the Company and its subsidiaries.

     The  Committee   believes   senior   management  of  the  Company  and  its
subsidiaries  should have a  significant,  ongoing  personal  investment  in the
Company.  To that end,  awards  tied to  Company  stock,  in  addition  to being
compensatory  in nature,  are used to encourage  targeted  levels of  individual
stock ownership.

     To promote the Company's long-term incentive objectives, the Company sought
and obtained  shareholder approval of the Pinnacle West Capital Corporation 2002
Long-Term  Incentive Plan (the "2002 Plan") at the 2002 Annual  Meeting.  Awards
and  grants  under the 2002  Plan are made at the  discretion  of the  committee
responsible for administering the 2002 Plan. In June 2002, three forms of awards
were granted under the 2002 Plan to executive  officers and other key employees.
The types of awards and the terms of the awards  under the 2002  grants  were as
follows:

     *    Performance-accelerated  stock options.  Under these awards, the stock
          options vest 33% each year;  however,  the last two vesting periods of
          the normal three-year  vesting period will be accelerated by up to one
          year if the Company's annual earnings per share growth exceeds that of
          the S&P Electric Utilities Index. Value to the executive is determined
          through the stock option component only when the Company's stock price
          appreciates  above the price at the time the option was  granted.  The
          2002 stock  options  were  granted at an exercise  price of $38.37 per
          share.  See the 2002  Option  Grants  Table  on page 21 of this  proxy
          statement for additional information about the 2002 option grants.

     *    Performance  share  awards.  Under these  awards,  each  recipient  is
          entitled to receive  shares of common stock at the end of a three-year
          period based upon the Company's  earnings per share growth rate during
          that three-year  period compared to the earnings per share growth rate
          of all relevant companies in the S&P Electric Utilities Index. For the
          performance  share awards granted in 2002, the three-year  performance
          period is from January 1, 2002 to December 31, 2004.  The earnings per
          share  growth  rate  for  the  three-year  performance  period  is the
          compounded  annual-growth  rate of a company's earnings per share from
          continuing operations, on a fully diluted basis, during the three-year
          period.  The amount of shares  awarded is  determined by the Company's
          relative  percentile  ranking  in the  Index  during  the  three  year
          performance  period.  See the 2002  Performance  Share Awards table on
          page 22 of this proxy statement for additional  information  regarding
          2002 performance share awards.

     *    Stock ownership awards.  Under these awards,  each recipient who owned
          an amount of stock equal to a specified  multiple of base salary,  was
          entitled  to receive up to 4% of the number of shares of common  stock
          owned by the recipient  during 2002 if the Company's 2002 earnings met
          a specified threshold.  The share ownership requirements for executive
          officers  are 5 times base salary in the case of the CEO; 3 times base
          salary in the case of the presidents of the Company,  APS, and PWEC; 2
          times base salary in the case of executive vice  presidents and senior
          vice  presidents;  and 1.75 times base salary in the case of all other
          officers.  The 2002 earnings threshold was not met, so no common stock
          was granted under the stock ownership awards.

                                       17

     A select committee, currently consisting of Ms. Grant and Messrs. Herberger
and Jamieson,  administers the Company's  stock-based  compensation  plans. This
committee  determines the size of awards in part by assessing  competitive grant
practices for comparable  positions and by allocating equity awards based on the
executive's contributions to the organization.

     OTHER  PROGRAMS.  The Company  also  provides its officers and key managers
with life and medical  insurance;  pension,  savings and  compensation  deferral
programs;  and other benefits and perquisites  that are competitive  with market
practices.

HOW IS THE COMPANY'S CEO COMPENSATED?

     The Committee reviews and approves corporate goals and objectives  relevant
to the CEO's  compensation,  assesses  the CEO's  performance  in light of these
goals  and  objectives  and  sets the  CEO's  compensation  level  based on this
assessment.  In determining the CEO's compensation,  the Committee considers the
Company's  performance and relative  shareholder  return, the value of incentive
awards to chief executive officers at comparable companies, and the awards given
to the CEO in past years.  As part of the  Committee's  strategy in aligning CEO
compensation with Company  performance and shareholder  return, Mr. Post's total
annual  compensation  is  targeted at the median of the  compensation  analysis;
however,  his base salary is designed to be below the median of the compensation
analysis,  with an offsetting  higher annual incentive  opportunity,  so that if
performance  objectives  are met, Mr.  Post's total cash  compensation  would be
competitive. In 2002, his total annual compensation was below the median.

     In  December  2002,  Mr.  Post's  salary as Chairman of the Board and Chief
Executive  Officer  of the  Company  and as  Chairman  of the  Board  and  Chief
Executive  Officer of APS was increased from $600,000 to $750,000.  This was the
first  increase in Mr.  Post's base salary since  November  2000.  The Committee
provided this increase to Mr. Post in order to recognize  his  contributions  to
the  Company  and in order to move his base  salary  closer to the median of the
compensation  analysis.  However,  consistent  with  the  compensation  approach
discussed in the preceding paragraph,  his salary still remains below the median
salary level of chief executive officers in the compensation analysis.

     For 2002, the Committee  established an incentive  payment  program for Mr.
Post based upon Company earnings and individual  performance.  The award granted
to Mr. Post under his annual  incentive  program was $250,000,  or approximately
17% of his maximum incentive  opportunity.  Mr. Post's maximum award opportunity
under this program was 200% of his base salary.  During 2002,  Mr. Post was also
granted the stock options,  performance  shares and stock  ownership  incentives
reflected  in the  Summary  Compensation  Table on page  20.  These  awards  are
intended to meet the compensation objectives discussed above.

HOW IS THE COMPANY  ADDRESSING  INTERNAL REVENUE CODE LIMITS ON DEDUCTIBILITY OF
COMPENSATION?

     Publicly-traded  corporations  generally are not  permitted to deduct,  for
federal income tax purposes, annual compensation in excess of $1 million paid to
any of certain top executives,  except to the extent the compensation  qualifies
as  "performance-based."  While the  Committee  strongly  believes in  rewarding
performance  through  the  bonus  and  equity  participation  programs,  certain
features   of   these   programs   do  not   fit   the   law's   definition   of
"performance-based,"  and therefore  limited amounts of compensation  may not be
deductible.

HUMAN RESOURCES COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

     None of the  members  of the Human  Resources  Committee  is or has been an
employee of the Company.  There were no interlocking  relationships  between the
Company  and  other  entities  that  might  affect  the   determination  of  the
compensation  of the Company's  executive  officers.  Mr.  Gallagher is Chairman
Emeritus of Gallagher & Kennedy, PA, a law firm which provided legal services to
the Company in 2002 and which will  provide  such  services  in 2003.  APS had a
consulting  agreement  with Robert G. Matlock &  Associates,  Inc., of which Mr.
Robert G. Matlock is President  and Chief  Executive  Officer and  fifty-percent
owner.  During 2002,  the Company paid this company  $14,272.00  for  consulting
services  and  expenses  relating  to the  Company's  nuclear  operations.  This
consulting agreement was mutually terminated as of August 27, 2002.

 System Planning and Operations of APS


- ----------
(1)  The  value of the  restricted  stock is based on the  closing  price of the
     Company's common stock on the date the restricted stock was granted. Except
     as  described  for  Messrs.  Davis,  Levine,  Stewart  and  Wheeler  in the
     subsequent  sentences,  the  restrictions  lapse on restricted stock awards
     upon  (i) the  passage  of  three  years  from  the  date of  grant or upon
     retirement  after the age of 60 and (ii) the holding of certain  numbers of
     unrestricted  shares for certain periods of time as determined by the Human
     Resources Committee at the time of the grant. During 2002, Messrs. Stewart,
     Davis and Levine received 2,000 shares of restricted stock that vested upon
     the date of grant.  During  2001,  Mr.  Wheeler  received  6,000  shares of
     restricted  stock of which  3,000  shares  vested  upon his  arrival at the
     Company and the remaining  3,000 shares vested on the first  anniversary of
     his date of hire. Any dividends  paid on the restricted  stock will be held
     by the  Company  until the  restrictions  lapse.  The  number and value (at
     market) of aggregate  restricted  shareholdings as of the end of 2002 were:
     Mr. Post - 27,350 shares,  $932,362; Mr. Stewart - 10,500 shares, $357,945;
     Mr. Davis - 10,500 shares,  $357,945; Mr. Levine - 5,200 shares,  $177,268;
     Mr. Wheeler - 2,300 shares,  $78,407.  In addition,  as shown on page 22 of
     this proxy statement, in the 2002 Performance Share Awards table, the named
     executive officers were granted long-term incentive plan awards.  Under the
     terms of the grants,  whether a common stock payment,  if any, is made will
     not be determined until after the end of the performance  period.  However,
     in accordance with SEC reporting requirements, the number (based on target)
     and value (at market) of the 2002 Performance Share Awards as of the end of
     2002 were: Mr. Post - 21,600 shares,  $736,344; Mr. Stewart - 9,100 shares,
     $310,219;  Mr. Davis - 10,300 shares,  $351,127; Mr. Levine - 3,125 shares,
     $106,531; and Mr. Wheeler - 2,750 shares, $93,748.

(2)  The  amounts  in  this  column  for  2002   consist  of  Company   matching
     contributions to the Company's  employees' savings plan: Mr. Post - $5,500,
     Mr. Davis - $5,500,  Mr.  Levine - $5,500,  and Mr.  Wheeler - $2,595;  the
     above-market  portion of  interest  accrued  under a deferred  compensation
     plan: Mr. Post - $44,987,  Mr. Davis - $47,911,  Mr. Stewart - $20,103, Mr.
     Levine - $73,310,  and Mr. Wheeler - $6,461,  and life  insurance  premiums
     (and gross-up on the premium for Mr.  Stewart) paid by the Company for: Mr.
     Post - $6,495, Mr. Stewart - $21,624, and Mr. Levine - $2,087.

(3)  Mr. Wheeler joined the Company as an executive officer in June of 2001.

WHAT OPTIONS WERE GRANTED TO THE NAMED EXECUTIVE OFFICERS IN 2002?

     The following table sets forth information with respect to option grants to
the named  executive  officers  during 2002. In the third  quarter of 2002,  the
Company  changed  to  the  fair  value  method  of  accounting  for  stock-based
compensation,  as  provided  for in SFAS No.  123.  The  fair  value  method  of
accounting  is  the  preferred   method.   In  accordance  with  the  transition
requirements of SFAS No. 123, the Company applied the fair method prospectively,
beginning  with the 2002 stock grants.  In prior years,  we  recognized  expense
based on the intrinsic value method allowed in APB No. 25.

- ----------
(1)  Performance  Options are subject to special  vesting  schedules that may be
     accelerated  based  upon the  achievement  of  pre-established  performance
     targets determined by the Committee.  Options vest annually in installments
     of 33% per year  beginning on the first  anniversary  of the date of grant.
     Upon achievement of the annual performance targets, the vesting period will
     be accelerated by as much as one year. All options not already  exercisable
     will become  exercisable if an individual retires on or after the age of 60
     or,  at  the  Human  Resources   Committee's   discretion,   under  certain
     circumstances. No SARs have been granted.

(2)  The Black-Scholes  option-pricing  model was chosen to estimate the present
     value. The basic assumptions used in the model were expected  volatility of
     22.59%;  risk-free rate of return of 4.17%;  dividend  yield of 4.17%;  and
     time to exercise of five years.  The actual value to an executive,  if any,
     will depend on whether the stock price appreciates above the exercise price
     at the time the option is exercised. The grant date present value set forth
     in the table is provided in accordance  with the valuation  methodology set
     forth in the SEC requirements.

(1)  Value  of  options  exercised  is the  market  value of the  shares  on the
     exercise date minus the exercise price.

(2)  The value of unexercised  options equals the market value of Company common
     stock on December 31, 2002  ($34.09 per share) minus the exercise  price of
     options.

(3)  Messrs.  Davis and Levine retained all shares received upon the exercise of
     options,  except for those sold  solely for the  purpose of meeting  option
     costs and tax-withholding requirements.

Except for Mr. Stewart, who is discussed separately below, the performance share
awards  in  the  preceding  table  are  payable  at the  end  of the  three-year
performance period. The amount of the payout may increase or decrease based upon
the  Company's  earnings  per share  growth rate as compared to the earnings per
share growth rate of the S & P Utilities  Index during the  performance  period.
The amount of the payout will be determined by the percentile  relative ranking;
however,  in no event  will an  employee  be  entitled  to  receive  a number of
performance  shares  greater  than two times the base grant.  The  Company  will
accrue  and hold any  dividends  on the  performance  shares  until the award is
vested and distributed.

(1)  Mr.  Stewart's  award will become payable at the time of his retirement and
     is not subject to the same performance criteria as noted above, nor will he
     be entitled to receive an amount greater than the initial shares awarded to
     him.

WHAT ARE THE COMPANY'S EXECUTIVE BENEFIT PLANS?

   EMPLOYEES' RETIREMENT PLAN AND SUPPLEMENTAL EXCESS BENEFIT RETIREMENT PLAN

     The Company maintains a tax-qualified, non-contributory retirement plan for
salaried  employees  and a  Supplemental  Excess  Benefit  Retirement  Plan that
provides  additional  retirement  benefits  for  key  salaried  employees.   The
following table illustrates the annual benefits that would be provided under the
Company  Employees'   Retirement  Plan  and  the  Supplemental   Excess  Benefit
Retirement  Plan to the  Company's  officers  retiring at age 65 or later at the
indicated compensation and years of service levels.

(1)  Benefits are calculated on a straight-life  annuity basis.  Benefits listed
     in the Table are not  subject to  deductions  for Social  Security or other
     offset amounts.

     Compensation  under  the  Employees'  Retirement  Plan  consists  solely of
average base  compensation  up to $200,000  (as  adjusted  for  cost-of-living),
including any amounts  voluntarily  deferred under the Company's 401(k) plan and
salary reduction  contributions  under the Company's  flexible benefits plan and
its qualified  transportation  arrangement  under Section 132(f) of the Internal
Revenue  Code.  The  Employees'   Retirement   Plan  does  not  include  amounts
voluntarily  deferred  under  other  deferred  compensation  plans,  bonuses  or
incentive pay. The  Supplemental  Excess Benefit  Retirement  plan does include,
subject to certain exceptions,  these additional components of compensation plus
base salary beyond the $200,000 limit. Benefits payable under this plan that are
in excess of the benefits  payable under the  Employees'  Retirement  Plan (as a
qualified  defined  benefit  pension plan,  the  Employees'  Retirement  Plan is
limited  pursuant to the  Internal  Revenue  Code) are payable  from the general
assets of the Company. For purposes of the retirement plans, the average monthly
compensation is the average of the highest 36 consecutive months in the final 10
years of employment.

     The number of  credited  years of service  for each of the named  executive
officers and the average  monthly  compensation  upon which  payments  under the
Employees'  Retirement Plan and the

                                       23

Supplemental  Excess Retirement  Benefit Plan would be based, as of December 31,
2002,  are as  follows:  Mr.  Post - 30 years,  $99,408;  Mr.  Davis - 30 years,
$59,187; Mr. Stewart - 9 years,  $60,079,  however, Mr. Stewart is entitled to a
pension  benefit  equal to 80% of his  average  monthly  wage on the date of his
retirement,  regardless  of his  years of  service,  using his  current  average
monthly wage of $60,079,  his annual  benefit,  calculated on the  straight-life
basis,  currently equals $48,063 (see  description of Mr.  Stewart's  employment
agreement  below);  Mr. Levine - 18 years,  $44,087,  notwithstanding  the table
above,  Mr.  Levine's  pension  benefit  will  increase by 3% of average  annual
compensation  for each additional year of service to age 60, so that his pension
benefit will equal 70% of his average annual compensation if he remains employed
until age 60 (see description of Mr. Levine's  employment  agreement below); and
Mr. Wheeler - 14 years (see  description of Mr. Wheeler's  employment  agreement
below), $31,524. Except with respect to Mr. Wheeler, who is discussed separately
below,  although years of service begin  accumulating on the date of employment,
benefits do not vest until the completion of five years of service.

     In 1986 Mr. Post, and in 1984 and 1985 Mr. Davis, participated in Option II
of the Arizona Public Service Company Deferred  Compensation  Plan,  pursuant to
which, each will receive an annual payment for a ten-year period following their
retirement  from the Company (the  "Option II Plan").  The Option II Plan allows
the  participant  to elect the  post-retirement  year in which  the  installment
payments begin, provided the initial year is on or after the participant reaches
sixty years of age and on or before the  participant  reaches  seventy  years of
age.  Under the Option II Plan,  in the event Mr. Post elects to begin  payments
following his retirement upon reaching 60 years of age, his annual payment would
be  $162,020.  In the event Mr.  Davis elects to begin  payments  following  his
retirement  upon reaching 60 years of age, his annual payment would be $152,037.
Each year thereafter that the initial payment is delayed, the annual installment
increases by 6.5%. The annual payments under the Option II Plan are forfeited if
the participant is not employed by the Company or one of its subsidiaries at the
time he  becomes  available  for early  retirement  (age 55),  in which case the
participant is only entitled to receive amounts the  participant  contributed to
the Option II Plan, plus interest.  This forfeiture  provision does not apply if
the  participant  fails to reach  retirement  age with the Company or one of its
subsidiaries as a result of death.

EMPLOYMENT AND SEVERANCE AGREEMENTS

     Under an employment  agreement  entered into in December of 1999 as amended
effective  as of January 1, 2002,  between Mr.  Stewart  and APS,  APS agreed to
provide to Mr.  Stewart a line of credit up to $1.2 million,  drawable  annually
beginning January 3, 2000 in $400,000  increments with interest payable at 7.5%.
All outstanding amounts are due March 31, 2005. Under the employment  agreement,
Mr. Stewart defers $400,000 in salary per year for a three-year period beginning
in the year 2000,  and the deferrals  are credited with interest  payable at 9%.
The Company must pay deferred  amounts to Mr.  Stewart in a lump sum in 2005. In
addition,  Mr.  Stewart is  entitled  to one  additional  payment of $800,000 on
January 3, 2005.  The  agreement  further  provides that Mr.  Stewart's  pension
benefit will be 80% of his average monthly wage on the date of his retirement.

     The Company and Mr.  Wheeler  entered  into a letter  agreement  in June of
2001,  pursuant to which Mr. Wheeler received an annual base salary of $275,000,
an  employment  incentive of $100,000 and 3,000 shares of Company  stock.  Under
this  agreement,  effective  July 1, 2002,  Mr.  Wheeler's  annual  base  salary
increased  to $300,000  and he received an  additional  3,000  shares of Company
stock.  Mr.  Wheeler  was also  credited  with ten years of vested  service  for
purposes of calculating his pension,  effective as of June 29, 2001. Mr. Wheeler
also receives two years of service for pension purposes in each of the first two
years of employment.

                                       24

     APS and Mr. Levine entered into a five-year  employment agreement effective
as of October 1,  2002.  The  agreement  provides  for Mr.  Levine to receive an
annual base salary of  $550,000.  Mr.  Levine is also  entitled to an  incentive
bonus  of up to 60% of base  salary  with a target  level of 40% of base  salary
under  the  officer  incentive  plan  if  certain  corporate,  departmental  and
individual  targets are met.  Consistent with the employment  agreement,  during
2002 the Human Resources  Committee granted Mr. Levine  performance  accelerated
stock options and  performance  share awards under the 2002 Plan (see "Executive
Compensation  -  Option  Grants  During  2002"  and  "Executive  Compensation  -
Long-Term   Incentive  Plan  Awards  During  2002"  for  information  about  the
performance  accelerated  stock options and performance  share awards granted to
Mr. Levine during 2002).  During each year of his employment  agreement,  APS is
also  required to request that the Human  Resources  Committee  grant Mr. Levine
2000  performance  shares  under  the  2002  Stock  Plan,  without  any  vesting
requirement.  The 2002  grant of these  performance  shares  is  reflected  as a
"Restricted  Stock  Award" in the Summary  Compensation  Table.  Mr.  Levine was
credited  with an  additional  five  years  of  service  for  pension  purposes,
resulting in a total of eighteen  years of service as of January  2002,  and his
pension  benefit  grows at 3% per year until his benefit  reaches 70%,  which is
scheduled  to occur  when he  reaches  age sixty.  Mr.  Levine may also  receive
additional  incentive  bonuses upon the Palo Verde  Nuclear  Generating  Station
maintaining specified federal and nuclear oversight program ratings, for nuclear
safety and for successful outage results.

     The Company has entered into identical  severance  agreements  with each of
its  executive  officers.  The Company  intends  that these  agreements  provide
stability in its key management in the event the Company experiences a change of
control.  The  agreements  provide for certain  payments if, during the two-year
period following a change of control of the Company,  the Company  involuntarily
terminates the officer's  employment or the executive  terminates his or her own
employment  following a significant  and  detrimental  change in the executive's
employment.  The termination  payment, if required,  is an amount equal to three
times the sum of the  executive's  annual salary at  termination  plus an annual
bonus,  as  determined  by  an  average  over  the  last  four  years  preceding
termination. In addition, the executive is entitled to continued medical, dental
and  group  life  insurance  benefits  at a shared  cost for  three  years.  The
termination is treated as a normal  termination under the Company's stock option
and benefit plans,  and outplacement  services are provided.  If Section 4999 of
the  Internal  Revenue  Code  imposes  an excise tax on all or part of the total
payments,  the agreement  further  provides for an  additional  gross up payment
equal to the excise tax (plus any  penalties  and  interest)  imposed on or with
respect to the total payments.  "Change of control"  includes:  (1) an unrelated
third party's  acquisition of 20% or more of the Company's or APS' voting stock;
(2) a merger or consolidation  where either the Company or APS combines with any
other  corporation  such that the  Company's  or APS'  outstanding  voting stock
immediately  prior to merger or  consolidation  represents  less than 60% of the
voting   stock  of  the  Company  or  APS   immediately   after  the  merger  or
consolidation,  but excluding a merger or consolidation  effected to implement a
recapitalization in which no unrelated third party acquires more than 20% of the
voting stock of the Company or APS; (3) the  shareholders  of either the Company
or APS approve a sale, transfer or other disposition of all or substantially all
of the assets of the Company or APS to an unrelated third party; or (4) the case
where the  composition of either the Board of the Company or of APS changes such
that the members of the Board of the Company (the "Company  Incumbent Board") or
of APS (the "APS Incumbent Board"),  as of July 31, 1999, no longer comprises at
least 2/3 of the  Company's  or APS' Board of  Directors.  For  purposes of this
latter  provision,  a person  elected to either  Board after July 31,  1999,  is
treated as a member of the Company Incumbent Board or APS Incumbent Board if his
or her nomination or election by shareholders  was approved by a 2/3 vote of the
members then comprising the Company  Incumbent Board or APS Incumbent Board, and
it does not  include  anyone who became a  director  in an actual or  threatened
election  contest relating to the election of directors.  No severance  benefits
will  be  payable  to  an  officer  whose  termination  is  due  to  retirement,
disability,  death,  voluntary  termination,  or for  "cause"  as defined in the
agreements. Each of the agreements terminates

                                       25

on December 31st of each year upon six months  advance  notice by the Company to
the officer;  if the six months advance notice is not given, the agreements will
continue for successive one-year periods until the notice is given.

     Effective January 1, 1992, the Company established a deferred  compensation
plan for  directors  and  officers  of the  Company  pursuant  to which  amounts
deferred are credited  with interest at rates  determined by the plan  committee
appointed by the Board (the  "General  Plan").  Effective  January 1, 1996,  the
Company  established  a revocable  trust to fund the benefits  under the General
Plan, the Option II Plan, and certain other  benefits.  Upon the occurrence of a
"change of control"  within the meaning of the General  Plan and the trust,  the
interest rate under the General Plan shall be the enhanced rate  established  by
the plan committee,  and the trust will become  irrevocable and the Company will
be required to fully fund the  benefits  earned  under the General  Plan and the
Option II Plan within 60 days after the occurrence of that event. The "change of
control," for purposes of the plans and trust,  is defined in the same manner as
the  "change  of  control"  definition  contained  in the  severance  agreements
described above.

                       PROPOSAL 2 -- SHAREHOLDER PROPOSAL

WHAT IS THE SHAREHOLDER'S PROPOSAL?

THE COMPANY IS NOT RESPONSIBLE FOR THE CONTENT OF THIS  SHAREHOLDER  PROPOSAL OR
SUPPORTING STATEMENT.

The Company has been advised that the Arizona  Safe Energy  Coalition  (owner of
record of 66.921 shares, as of the record date), c/o Betty Schroeder,  5349 West
Bar X Street, Tucson, Arizona 85713 intends to present the following proposal at
the 2003 Annual  Meeting.  The  proposal  and  supporting  statement  exactly as
submitted to the Company,  are set forth below.  The Board of Directors  opposes
this proposal for the reasons stated on pages 27-28.

WHEREAS:

As long as Palo Verde's nuclear reactors operate,  they will continue generating
radioactively and thermally hot, irradiated fuel rods that must be cooled, after
removal from the Reactor Vessel,  and placed in wet storage in the on-site Spent
Fuel Pool for at least five years before they can be moved.

In 2002 the President and Congress approved the siting of a federal  underground
repository for irradiated fuel rods at Yucca Mountain, Nevada. The repository is
not yet finally  designed or licensed;  its  construction  will not be completed
until at least 2010. The nuclear industry describes Yucca Mountain as one single
site where all the nation's irradiated fuel rods could be consolidated. However,
since  the  irradiated  rods of each  plant  must be kept at that  plant's  site
temporarily,  submerged in water,  highly  radioactive  rods will continue to be
scattered at operating  plants  nationwide  as long as nuclear  plants  continue
operating. The irradiated fuel rods must be kept isolated from the biosphere for
hundreds of thousands of years.

Capacity at Yucca  Mountain is limited by law.  Older  irradiated  fuel rods now
being stored at older reactors will have priority for disposal space.  There may
not be room  for a  sizable  amount  of Palo  Verde's  fuel  rods in this  first
national repository.

The US Nuclear  Regulatory  Commission has granted many utilities  permission to
store far more  irradiated rods in on-site fuel pools than was intended in their
initial  design.  Robert  Alvarez,  a former  Energy  Department  senior  policy
advisor, told a Senate hearing, "An attack against a spent fuel pool

                                       26

could drain enough water to cause a catastrophic  radiological  fire that cannot
be  extinguished."  He  cited  a 1997  analysis  that  said  such  a fire  could
contaminate up to 188 square miles.

On February 7, 2002,  Homeland  Security Director Tom Ridge said that structural
changes may be necessary to fortify nuclear plants against September 11 kinds of
attacks,  and other  threats  not  previously  considered.  He said,  "there may
ultimately be some actual bricks and mortar adjustments that are made to some of
these facilities."

Construction  on-site  at Palo Verde  reactors,  of  fortified  bunkers or other
structures  (below- or  partially  below-  grade),  that can be  concealed  from
off-site locations and be safeguarded,  may be essential for the interim storage
on-site of Palo Verde's irradiated fuel rods.

RESOLVED:

In light of  heightened  public  safety  concerns,  we request  that the Company
prepare a report,  at reasonable  cost, that outlines the current  vulnerability
and substantial risks of the interim storage of irradiated fuel rods at the Palo
Verde Plant and that  proposes  measures to reduce  those  risks.  A copy of the
report,  omitting proprietary and security  information,  should be available to
shareholders on request by September 2003.

SUPPORTING STATEMENT:

Pinnacle West remains morally responsible and financially liable for Palo Verde,
for securing its radioactive  wastes,  and for protecting workers and the public
into the indefinite future. We believe this study is essential for realistic and
responsible economic and ethical planning.

WHAT IS THE BOARD'S RESPONSE TO THE PROPOSAL?

           BOARD OF DIRECTORS' STATEMENT AGAINST SHAREHOLDER PROPOSAL

     The  Company,  APS and the Palo Verde  Nuclear  Generating  Station  ("Palo
Verde") take pride in our commitment to safety. Protecting the health and safety
of the public as well as that of our  employees  is,  and always  will be, a top
priority.

     In 1982,  Congress  passed the Nuclear  Waste  Policy Act  ("NWPA"),  which
requires the federal government to permanently dispose of all spent nuclear fuel
generated  at the  nation's  nuclear  power  plants.  Pursuant to the NWPA,  the
Department of Energy  ("DOE") has entered into a contract with APS and the other
owners of Palo Verde for the disposal of spent nuclear fuel.  Thus,  the DOE has
both a contractual and a statutory  obligation to take possession and dispose of
all of the  spent  nuclear  fuel  generated  at Palo  Verde.  In 2002,  Congress
approved  the  Yucca  Mountain  site in  Nevada as the  nation's  nuclear  waste
repository.  The DOE, which has responsibility for building Yucca Mountain,  has
currently scheduled completion of that construction for 2010. However, the DOE's
obligation  to dispose of spent  nuclear fuel from Palo Verde is not  contingent
upon the completion of, or storage capacities at, Yucca Mountain.

     Until such time as the DOE fulfills its  obligation to take  possession and
dispose of the spent nuclear fuel  generated at Palo Verde,  the spent fuel will
be safely  stored  onsite in either  the spent  fuel  pools or dry fuel  storage
systems.  The Nuclear  Regulatory  Commission  ("NRC") is the federal government
agency that is responsible for licensing and regulating commercial nuclear power
plants.  This  responsibility  includes protecting the public health and safety,
and the environment, as well as safeguarding nuclear materials and nuclear power
plants in the interests of national security. The design and construction of the
spent fuel pools and the dry fuel storage systems at Palo Verde are approved and
licensed by the NRC.  Additionally,  the NRC also  regulates and inspects  their
operation.

                                       27

     After the terrorist  attacks of September 11, 2001, the NRC issued a number
of advisories to nuclear  power plant  licensees in order to further  strengthen
licensees'  capabilities  and  readiness  to respond to a potential  attack.  In
February 2002,  the NRC issued an order  modifying the licenses of all operating
nuclear power plants.  The NRC order  requires the  implementation  of specified
interim  safeguards and security  compensatory  measures in order to address the
generalized  high-level  threat  environment  post September 11, 2001. These new
requirements,  which  supplement  existing  requirements,  provide  the NRC with
reasonable  assurance  that the public health and safety and common  defense and
security  at  the  nation's  commercial  nuclear  power  plants  continue  to be
adequately protected.  Palo Verde implemented the measures required by the NRC's
order and the NRC has reviewed and inspected Palo Verde's actions and determined
that Palo Verde is in compliance.  At such time as the NRC imposes additional or
new  requirements,  Palo  Verde  will also take the steps  necessary  to meet or
exceed these requirements.

     In light of the actions that Palo Verde has taken to enhance  security,  as
well as the  continuing  NRC reviews in this area,  the Company does not believe
that it is necessary, prudent, cost-effective or in the best interest of nuclear
safety to  prepare a report  separate  and apart  from the  actions  or  ongoing
reviews being taken by the industry and the NRC.

     Because of the extensive security measures presently in place at Palo Verde
to protect the station, including its spent fuel, and the ongoing NRC reviews in
this area, the Board believes that this shareholder  proposal is not in the best
interests of the Company's shareholders.

THE BOARD OF DIRECTORS  UNANIMOUSLY  RECOMMENDS A VOTE AGAINST THIS  SHAREHOLDER
PROPOSAL.

                             ADDITIONAL INFORMATION

HOW DO WE SUBMIT SHAREHOLDER PROPOSALS FOR THE NEXT ANNUAL MEETING?

     Shareholders who intend to have their proposals considered for inclusion in
the proxy statement and form of proxy relating to the 2004 Annual Meeting of the
Company's shareholders and who wish to present the proposal at that meeting must
submit the  proposal in  accordance  with the  applicable  rules of the SEC. The
Company must receive the proposal at its principal executive office on or before
December  9, 2003.  Shareholders  who intend to  present  proposals  at the 2004
Annual Meeting but do not wish them included in the proxy  statement and form of
proxy must submit the  proposal by the close of business on February  21,  2004,
but not earlier  than  January  22,  2004,  in  accordance  with the  applicable
provisions of the Company's  Bylaws,  a copy of which is available  upon written
request  to the Office of the  Secretary.  If a  shareholder  submits a proposal
after the close of business on February 21, 2004,  the  Company's  proxy holders
will be allowed to use their discretionary  voting authority to vote against the
proposal  when and if the  proposal  is raised at the 2004 Annual  Meeting.  The
Company  suggests that  proponents  submit their  proposals to the Office of the
Secretary by Certified Mail - Return Receipt Requested.

HOW MANY ANNUAL REPORTS AND PROXY STATEMENTS ARE DELIVERED TO A SHARED ADDRESS?

     If you and  one or more  shareholders  of  Company  stock  share  the  same
address,  it is possible  that only one annual  report and proxy  statement  was
delivered  to your  address.  This is known as  "householding."  Any  registered
shareholder  who wishes to receive  separate copies of an annual report or proxy
at the same address now or in the future may:

     *    call Shareholder Services at 1-800-457-2983;
     *    mail a request to receive  separate copies to Shareholder  Services at
          P.O. Box 52133, Phoenix, AZ 85072-2133; or
     *    e-mail a request to: shareholderdept@pinnaclewest.com.

     Shareholders who own Company stock through a broker and who wish to receive
separate  copies of an annual report and proxy  statement  should  contact their
broker.

     Shareholders  currently  receiving  multiple copies of an annual report and
proxy at a shared  address  and who wish to  receive  only a single  copy in the
future may direct their request to the same phone number and addresses.

HOW MUCH DID THIS PROXY SOLICITATION COST?

     The Board of Directors is soliciting the enclosed proxy.  The Company bears
the cost of the  solicitation  of proxies.  Proxies are primarily  sent by mail,
although the Company may solicit consenting  shareholders over the internet. The
Company has retained Georgeson Shareholder Communications, Inc. to assist in the
distribution of proxy solicitation materials and the solicitation of proxies for
approximately  $7,500. As required,  the Company will reimburse brokerage houses
and  others  for  their  out-of-pocket   expenses  in  forwarding  documents  to
beneficial owners of stock.

                             AUDIT COMMITTEE CHARTER

                                (March 19, 2003)

I.   GENERAL

     The  Audit  Committee  is a  committee  of the  Board of  Directors  of the
     Company.  Its primary function is to assist the Board in monitoring (1) the
     integrity  of the  Company's  financial  statements,  (2)  the  independent
     auditor's  qualifications  and  independence,  (3) the  performance  of the
     Company's  internal audit function and  independent  auditors,  and (4) the
     compliance by the Company with legal and regulatory requirements.

     The Audit  Committee  shall prepare the report required by the rules of the
     Securities and Exchange Commission (the "Commission") to be included in the
     Company's annual proxy statement.

     The Audit Committee will report regularly to the Board.

II.  COMMITTEE COMPOSITION AND MEMBER QUALIFICATIONS

     The Audit  Committee  will consist of three or more  directors who meet the
     independence  and  experience  requirements  of the New York Stock Exchange
     ("NYSE").

     No Audit Committee member may  simultaneously  serve on the audit committee
     of more than three public companies, including the Company.

     Each member of the Audit Committee must meet the independence  requirements
     of Section 10A(m)(3) of the Securities  Exchange Act of 1934 (the "Exchange
     Act"),  as reflected in Commission  Release No. 33-8173  (January 8, 2003).
     Under  these  requirements,  a member  of the Audit  Committee  will not be
     considered  independent if he or she (i) accepts any consulting,  advisory,
     or  other  compensatory  fee  from the  Company  (other  than in his or her
     capacity  as a  member  of the  Board or a Board  committee)  or (ii) is an
     affiliated person of the Company or any of its subsidiaries. The Board will
     determine   whether  the  Audit   Committee   members   meet  the  required
     independence standards.

     At least one  member of the Audit  Committee  shall be an "audit  committee
     financial expert," as defined by the Commission.

     The Board will  select the  members of the Audit  Committee  on at least an
     annual basis. Members of the Audit Committee may be removed by the Board at
     any time.

III. MEETINGS

     The Committee will meet as often as it determines,  but not less frequently
     than  quarterly.  The  Committee  may create  subcommittees  and vest those
     subcommittees  with the  authority  of the full  Committee  with respect to
     specific matters delegated to such subcommittees.

     The  Committee  will  meet  separately,  at least  quarterly,  with each of
     management, the internal auditors, and the independent auditor.

          for the  purpose of  preparing  or issuing an audit  report or related

          the DE MINIMUS  exceptions for non-audit services described in Section
          10A(i)(1)(B)  of the  Exchange  Act  which are  approved  by the Audit
          Committee  prior to the completion of the audit.  The Audit  Committee
          may form and delegate authority to subcommittees  consisting of one or
          more  members  when  appropriate,  including  the  authority  to grant
          preapprovals of audit and permitted non-audit services,  provided that
          decisions of such subcommittee to grant  preapprovals are presented to
          the full Audit Committee at its next scheduled meeting.

     (3)  The Audit Committee  shall have the authority,  to the extent it deems
          necessary or appropriate,  to retain independent legal, accounting, or
          other advisors.  The Company shall provide for appropriate funding, as

          (d) all relationships between the independent auditor and the Company.
          In addition to discussing the foregoing  matters with the  independent

V.   AUDIT COMMITTEE'S ROLE - GENERAL

     While the Audit Committee has the  responsibilities and powers set forth in
     this Charter,  it is not the duty of the Audit Committee to plan or conduct
     audits or to determine that the Company's financial statements are complete
     and accurate  and are in  accordance  with  generally  accepted  accounting
     principles.  This is the  responsibility  of management and the independent
     auditor.   Nor  is  it  the  duty  of  the  Audit   Committee   to  conduct
     investigations  or to assure  compliance  with laws and regulations and the
     Company's Ethics Policy and Standards of Business Practices.

     This Audit  Committee  Charter  is not  intended  to change or augment  the
     obligations of the Company or its directors or management under the federal
     securities  laws  or  to  create  new  standards  for  determining  whether
     directors or management  have fulfilled their duties,  including  fiduciary
     duties, under applicable state law.

                         DIRECTOR INDEPENDENCE STANDARDS

BACKGROUND

     The New York Stock Exchange ("NYSE") has proposed amendments to its listing
standards  to require  NYSE-listed  companies,  such as the  Company,  to have a
majority of "independent  directors." On March 12, 2003, the NYSE filed with the
Securities and Exchange  Commission  (the "SEC"),  proposed rules (the "Proposed
Rules")  regarding  director  independence.  The Proposed  Rules amend  proposed
director  independence rules the NYSE filed with the SEC on August 16, 2002. The
Proposed  Rules  include a list of  relationships  that would prevent a director
from being independent under NYSE listing standards.  Commentary to the Proposed
Rules includes the following language on this topic:

     It is not  possible  to  anticipate,  or  explicitly  to provide  for,  all
     circumstances  that might signal potential  conflicts of interest,  or that
     might bear on the  materiality  of a  director's  relationship  to a listed
     company.  Accordingly,  we think it best that boards making  "independence"
     determinations  broadly consider all relevant facts and  circumstances.  In
     particular,  when assessing the  materiality  of a director's  relationship
     with the company,  the board should  consider the issue not merely from the
     standpoint of the director,  but also from that of persons or organizations
     with which the  director has an  affiliation.  Material  relationships  can
     include commercial,  industrial,  banking,  consulting,  legal, accounting,
     charitable,  and familial  relationships  (among  others).  The basis for a
     board determination that a relationship is not material should be disclosed
     in the company's annual proxy statement.

     In discussing a board's  determination of the "independence" of a director,
commentary to the Proposed Rules includes the following language:

     [A]  board may adopt and  disclose  categorical  standards  to assist it in
     making determination of independence,  and may make a general disclosure if
     a director meets these standards.  Any  determination of independence for a
     director who does not meet these standards must be specifically  explained.
     A company  must  disclose  any  standard  it  adopts.  It may then make the
     general statement that the independent  directors meet the standards set by
     the board  without  detailing  the  particular  aspects  of the  immaterial
     relationships between individual directors and the company.

     In furtherance of proactive corporate governance  practices,  the Company's
Board of Directors  believes it is appropriate  to adopt  director  independence
standards  designed  to comply  with the  Proposed  Rules and to  evaluate  each
director's  independence  in light of these  standards.  The Board of  Directors
recognizes that the final NYSE listing  standards on director  independence  may
require modification of these Director Independence Standards or ratification or
reevaluation of director independence determinations.

DIRECTOR INDEPENDENCE STANDARDS

(1)  For  purposes  of  these   Director   Independence   Standards,   the  term
     "Independent"  has the meaning  ascribed to such term in the Proposed Rules
     requiring  NYSE-listed  companies  to  have  a  majority  of  "independent"
     directors.

(2)  The Company will publicly disclose director independence  determinations in
     accordance with NYSE rules and/or applicable law.

                                       38

(3)  No  director  qualifies  as  Independent  unless  the  Board  of  Directors
     affirmatively  determines  that the director  has no material  relationship
     with the Company (either directly or as a partner,  shareholder, or officer
     of an organization that has a relationship with the Company). The Board may
     make this  determination upon its finding that a director does not have any
     of the relationships or interests described in Paragraphs 4-7 below.

(4)  A director who receives or whose  immediate  family member  receives,  more
     than  $100,000 per year in direct  compensation  from the Company or any of
     its  subsidiaries,  other than director and  committee  fees and pension or
     other forms of  deferred  compensation  for prior  service  (provided  such
     deferred compensation is not contingent in any way on continued service) is
     presumed not to be  Independent  until five years after he or she ceases to
     receive  more than  $100,000  per year in such  compensation.  The Board of
     Directors  may negate this  presumption  with  respect to a director if the
     Board  determines (and no Independent  director  dissents) that, based upon
     the relevant facts and circumstances, such compensatory relationship is not
     material.

(5)  A director who is affiliated with or employed by, or whose immediate family
     member is  affiliated  with or employed in a  professional  capacity  by, a
     present or former  auditor of the  Company  is not  Independent  until five
     years after the end of either the affiliation or the auditing relationship.

(6)  A director who is employed, or whose immediate family member is employed as
     an executive  officer of another company where any of the Company's present
     executive officers serves on that company's  compensation  committee is not
     Independent  until  five  years  after  the  end  of  such  service  or the
     employment relationship.

(7)  A director who is an executive  officer or an employee,  or whose immediate
     family member is an executive officer, of another company (a) that accounts
     for at least 2% or $1  million,  whichever  is  greater,  of the  Company's
     consolidated  gross revenues,  or (b) for which the Company accounts for at
     least 2% or $1  million,  whichever  is  greater,  of the  other  company's
     consolidated  gross revenues,  in each case is not  Independent  until five
     years after falling below such threshold.

(8)  For purposes of Paragraphs 4-7 above (a) immediate  family members  consist
     of  a  person's   spouse,   parents,   children,   siblings,   mothers  and
     fathers-in-law, sons and daughters-in-law, brothers and sisters-in-law, and
     anyone who shares  such  person's  home,  and (b) the five year "look back"
     period will not include any years before January 1, 2002.

(9)  Nothing in these  Director  Independence  Standards  prohibits the Board of
     Directors  from  determining  that a director is not  Independent  based on
     other   relationships  or  transactions   not  specifically   described  in
     Paragraphs 4-7 above.

(10) Nothing in these  Director  Independence  Standards  prohibits the Board of
     Directors from adopting additional or different qualifications for director
     membership  on  a  Board   committee,   it  being   understood   that  such
     qualifications  will be  separately  approved by the Board and  included in
     such Board committee's charter.

Effective as of March 19, 2003.
