INDEPENDENT AUDITORS' REPORT

To the Trustees and Participants of
The Pinnacle West Capital Corporation Savings Plan
Phoenix, Arizona

We have audited the accompanying statements of net assets available for benefits
of The Pinnacle West Capital Corporation Savings Plan (the "Plan") as of
December 31, 2000 and 1999, and the related statements of changes in net assets
available for benefits for the years then ended. These financial statements are
the responsibility of the Plan's management. Our responsibility is to express an
opinion on these financial statements based on our audits.

We conducted our audits in accordance with auditing standards generally accepted
in the United States of America. Those standards require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, such financial statements present fairly, in all material
respects, information regarding the Plan's net assets available for benefits as
of December 31, 2000, and the changes therein for the year then ended and its
financial status as of December 31, 1999, and the changes therein for the year
then ended in conformity with accounting principles generally accepted in the
United States of America.

Our audits were conducted for the purpose of forming an opinion on the basic
financial statements taken as a whole. The supplemental schedule of assets held
for investment purposes as of December 31, 2000, is presented for the purpose of
additional analysis and is not a required part of the basic financial
statements, but is supplementary information required by the Department of
Labor's Rules and Regulations for Reporting and Disclosure under the Employee
Retirement Income Security Act of 1974. This schedule is the responsibility of
the Plan's management. Such schedule has been subjected to the auditing
procedures applied in our audit of the basic 2000 financial statements and, in
our opinion, is fairly stated in all material respects when considered in
relation to the basic financial statements taken as a whole.

                                  SAVINGS PLAN

                          NOTES TO FINANCIAL STATEMENTS

1.   SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

          METHOD OF ACCOUNTING - The financial statements in this report reflect
     the total assets, liabilities and net assets available for benefits and
     changes therein of The Pinnacle West Capital Corporation Savings Plan (the
     "Plan"). The financial statements have been prepared in accordance with
     accounting principles generally accepted in the United States of America
     using the accrual basis of accounting. Investment transactions are recorded
     as of the trade date. Dividend income is recorded as of ex-dividend dates.

          INVESTMENTS - The Plan consists of a salary reduction arrangement and
     an employer matching contribution feature. The investment choices for the
     Plan during 2000 consisted of:

               Pinnacle West Stock Fund -- The fund consists primarily of common
          stock of Pinnacle West Capital Corporation ("Pinnacle West,"
          "Company," or "Employer"). The common stock is stated at fair value
          based on quoted market prices in an active market.

               Index Fund -- The fund consists of common stocks maintained by
          the Trustee (defined below) as part of a commingled fund. The fund is
          stated at fair value generally based on the last reported sales price
          on the last business day of the calendar year.

               Fixed Income Fund -- The fund consists primarily of several
          benefit-responsive guaranteed investment contracts with varying rates
          of interest and varying maturities. The fund is stated at contract
          value which approximates fair value.

               Aggressive Equity Fund -- The fund consists primarily of common
          stocks maintained by Putnam Investments as part of the Putnam Voyager
          Fund, Class A. The fund is stated at fair value generally based on the
          last reported sales price on the last business day of the calendar
          year.

               International Equity Fund -- The fund consists primarily of
          stocks outside the United States and is maintained by Deutsche Asset
          Management International Equity. The fund is stated at fair value
          generally based on the last reported sales price on the last business
          day of the calendar year.

               Conservative, Moderate and Aggressive Lifestyle Funds -- These
          funds consist primarily of cash, domestic stocks, international
          stocks, and domestic bonds and are maintained by the Vanguard Group as
          part of the Lifestrategy Portfolios.

                                        4

          Temporary investments - Temporary investments represent cash or other
     cash equivalents that are held until investments in other funds can be
     made.

          PAYMENT OF BENEFITS - Benefits are recorded when paid.

          USE OF ESTIMATES - The preparation of financial statements in
     conformity with accounting principles generally accepted in the United
     States of America requires management to make estimates and assumptions
     that affect the reported amounts of net assets available for benefits and
     changes therein. Actual results could differ from those estimates. The Plan
     utilizes various investment instruments. Investment securities, in general,
     are exposed to various risks, such as interest rate, credit, and overall
     market volatility. Due to the level of risk associated with certain
     investment securities, it is reasonably possible that changes in the values
     of investment securities will occur in the near term and that such changes
     could materially affect the amounts reported in the statements of net
     assets available for plan benefits.

2.   DESCRIPTION OF THE PLAN

          The following description of the Plan provides only general
     information. Participants should refer to the plan agreement for a more
     complete description of the Plan's provisions.

          GENERAL - The Plan is administered by a committee appointed by the
     Pinnacle West Board of Directors. The Plan is subject to the provisions of
     the Employee Retirement Income Security Act of 1974 ("ERISA"), as amended.

          Effective July 1, 1999, Norwest Bank of Minnesota N.A., which changed
     its name to Wells Fargo, Minnesota, N.A., effective January 1, 2000 (the
     "Trustee",) became the trustee of the master trust agreement in which the
     Plan, The Savings Plan for Employees of Arizona Public Service Company and
     The Savings Plan for Union Employees of Arizona Public Service Company
     (collectively referred to as the "APS Plans") participated. Prior to July
     1, 1999, State Street Bank and Trust Company was the trustee for this
     master trust.

          In June 1999, the Board of Directors of Pinnacle West and in July
     1999, the Board of Directors of Arizona Public Service Company ("APS")
     agreed to merge the APS Plans into the Plan effective December 31, 1999,
     thereby eliminating the need for the master trust. Pinnacle West continues
     to be the sponsor of the Plan.

          ELIGIBILITY - Generally, all active employees of Pinnacle West and its
     subsidiaries, including, APS, Pinnacle West Energy Corporation, APS Energy
     Services Company, Inc., El Dorado Investment Company and the active
     salaried employees of SunCor Development Company are eligible to
     participate in the pre-tax and after-tax features of the Plan upon

                                        5

     attaining age 21 and completing thirty-one days of consecutive employment
     and are eligible to participate in the matching feature upon attaining age
     21 and completing one year of service. Subject to the approval of the Board
     of Directors of the Company of an affiliate's participation in the Plan as
     a contributing employer, the Plan allows for participation by employees of
     a company that becomes an affiliate of Pinnacle West if such employees were
     formerly participants in a qualified plan sponsored by their employer,
     regardless of whether they have satisfied the Plan's other eligibility
     requirements.

          CONTRIBUTIONS - The Plan is a defined contribution plan. The Plan
     allows employees to contribute up to 16% of their base pay on a pre-tax
     basis and up to 16% of their base pay on an after-tax basis, provided that
     in no event would the total tax deferred and voluntary contributions made
     by any participant in any year exceed 16% of his or her base pay. The
     maximum allowable base pay ($170,000) and tax-deferred contribution
     ($10,500) are linked to the cost of living index and could change on an
     annual basis.

          Employer contributions are fixed at 50% of the first 6% of an
     employee's pre-tax contributions. The Employer contributions may be in
     cash, common stock or other property acceptable to the Trustee.

          The Plan allows rollover contributions from another qualified plan or
     individual retirement rollover account, subject to certain criteria.

          INVESTMENT CHOICES - Participants' contributions may be invested in
     one or more of the following funds: Pinnacle West Stock Fund, Index Fund,
     Fixed Income Fund, Aggressive Equity Fund, International Equity Fund,
     Conservative Lifestyle Fund, Moderate Lifestyle Fund, and Aggressive
     Lifestyle Fund. Information about the net assets and the significant
     components of the changes in net assets relating to the
     nonparticipant-directed investments is as follows as of December 31, 2000:

                                                                 2000
                                                             ------------
          Pinnacle West Stock Fund Net Assets - 12/31/99      $69,138,017
            Changes in net assets during 2000:
            Net appreciation                                   41,365,006
            Employer contributions                              8,317,161
            Benefits paid to participants                     (10,853,763)
                                                             ------------
          Pinnacle West Stock Fund Net Assets - 12/31/00     $107,966,421
                                                             ------------

          The 1999 balance of non-participant directed contributions includes a
     $67,374,910 transfer from The Savings Plan for Employees of Arizona Public
     Service Company and The Savings Plan for Union Employees of Arizona Public
     Service Company, as a result of the merger of the APS Plans and the Plan
     (see "General" above).

                                        6

          LOAN FEATURE - Participants may borrow money from their pre-tax
     contributions account, vested Employer contributions account and rollover
     account (if any). Participants may not borrow against their Employer
     transfer account or their after-tax contributions account.

          The minimum participant loan available is $1,000, and the maximum
     available is 50% of the participant's vested account balance, up to
     $50,000, reduced by the participant's highest outstanding loan balance in
     the 12-month period ending on the day before the loan is made. Only one
     loan per participant may be outstanding at any one time. Loan terms range
     from six months to five years, or up to 15 years for the purchase of a
     principal residence. An administrative fee is charged to the participant's
     account for each loan.

          The interest rate is determined at the time the loan is requested and
     is fixed for the life of the loan. The interest rate is the Trustee's prime
     interest rate plus one percent, determined as of the first business day of
     the month in which the loan is issued. Interest rates for loans issued
     during 2000 ranged from 8.75% to 9.50%.

          Loans are treated as an investment of the participant's accounts. To
     fund the loan, transfers are made from the participant's investment funds
     on a pro-rata basis. Loan repayments are invested in the participant's
     investment funds based on the participant's current investment election.
     Loan repayments, including interest, are generally made through irrevocable
     semi-monthly payroll deductions.

          VESTING - Each participant is fully vested as to the participant's
     contribution account (consisting of the participant's contributions and
     related income and appreciation or depreciation). The participants become
     vested in their Employer contribution account (consisting of Employer
     contributions and related income and appreciation or depreciation) in the
     event of termination of service by death, disability or retirement, upon
     attaining the age of sixty-five, upon completion of five years of service,
     upon termination of the Plan, or upon complete discontinuance of Employer
     contributions; otherwise, participants vest in graduated amounts with 100
     percent vesting in five years of plan participation, beginning with the
     first plan year of employee participation.

          WITHDRAWALS AND DISTRIBUTIONS - A participant may at any time make a
     full or partial withdrawal of the balance in the participant's after-tax
     contribution account and rollover contribution account. No withdrawals
     before retirement are permitted from a participant's transfer account. No
     withdrawals before retirement are permitted from the participant's pre-tax
     contribution account, except under certain limited circumstances relating
     to financial hardship. If an employee withdraws pre-tax contributions, the
     only earnings on those contributions that can be withdrawn are those
     credited prior to 1989. Generally, participants who are fully vested and
     who have participated in the Plan for five complete plan years may withdraw
     the amount in their Employer contribution account. When the participant's
     employment with the Company is terminated, the participant generally can
     elect to receive, as soon as administratively possible, a distribution of
     the vested portion of his or her Employer contribution account together
     with the participant's contribution accounts.

                                        7

          FORFEITURES - Forfeitures of nonvested Employer contributions will
     occur upon distribution following termination of employment with the
     Company. However, if a former participant again becomes an employee of the
     Company prior to the end of the fifth calendar year following the calendar
     year in which the participant's earlier termination of employment occurred,
     the forfeited Employer contributions will be restored to the participant's
     Employer contribution account, provided the participant repays the full
     amount previously distributed to him or her. Forfeitures are used to reduce
     future Employer contributions to the Plan.

          TERMINATION OF THE PLAN - It is the Company's present expectation that
     the Plan and the payment of Employer contributions will be continued
     indefinitely. However, continuance of any feature of the Plan is not
     assumed as a contractual obligation. The Company, at its discretion, may
     terminate the Plan and distribute net assets. In this event, the balance
     credited to the accounts of participants at the date of termination shall
     be fully vested and nonforfeitable.

3.   INCOME TAX STATUS

          A determination letter dated September 8, 1995 has been received from
     the Internal Revenue Service indicating that the Plan has been determined
     to be a qualified plan under the provisions of the Internal Revenue Code.
     The Plan has been amended since receiving the determination letter. The
     Company's management and plan administrator believes that the Plan is
     designed and is currently being operated in compliance with the applicable
     requirements of the Internal Revenue Code.

4.   GUARANTEED INVESTMENT CONTRACTS

          Under the benefit-responsive contracts, interest rates on guaranteed
     investment contracts ("GICs") vary within the Fixed Income Fund. The
     contracts held in the Plan have a weighted average crediting interest rate
     at December 31, 2000 of 6.44% and December 31, 1999 of 6.42%. The average
     yield for 2000 approximated the weighted average crediting interest rate.
     The crediting interest rates on the GICs may be reset on a quarterly or
     semi-annual basis, or may be fixed, based on the terms of the contract.

          Fourteen of the GICs are managed synthetic investment contracts. The
     fair value of the assets related to these contracts is $36,461,994. The
     contract value of these assets is $37,515,608.

5.   INVESTMENTS AND UNITS OF PARTICIPATION

          In accordance with the provisions of the Plan, the Trustee maintains
