                         ARIZONA PUBLIC SERVICE COMPANY
                     NOTES TO CONDENSED FINANCIAL STATEMENTS

1.   Our unaudited condensed financial statements reflect all adjustments which
we believe are necessary for the fair presentation of our financial position and
results of operations for the periods presented. These adjustments are of a
normal recurring nature with the exception of the cumulative effect of a change
in accounting for derivatives (see Note 10). We suggest that these condensed
financial statements and notes to condensed financial statements be read along
with the financial statements and notes to financial statements included in our
2001 10-K.

2.   Weather conditions cause significant seasonal fluctuations in our revenues.
Consequently, results for interim periods do not necessarily represent results
to be expected for the year.

3.   We are a wholly-owned subsidiary of Pinnacle West.

4.   On March 1, 2002, we issued $375 million of 6.5% Notes due 2012. On April
15, 2002, we redeemed $122 million of our First Mortgage Bonds, 8.75% Series due
2024. On March 15, 2002, we redeemed at maturity $125 million of our First
Mortgage Bonds, 8.125% Series due 2002. The above items represent the primary
changes in capitalization for the six months ended June 30, 2002.

5.   Regulatory Matters

ELECTRIC INDUSTRY RESTRUCTURING

STATE

     OVERVIEW. On September 21, 1999, the ACC approved Rules that provide a
framework for the introduction of retail electric competition in Arizona. On
September 23, 1999, the ACC approved a comprehensive settlement agreement among
us and various parties related to the implementation of retail electric
competition in Arizona. Under the Rules, as modified by the 1999 Settlement
Agreement, we are required to transfer all of our competitive electric assets
and services to an unaffiliated party or parties or to a separate corporate
affiliate or affiliates no later than December 31, 2002. Consistent with that
requirement, we have been addressing the legal and regulatory requirements
necessary to complete the transfer of our generation assets to Pinnacle West
Energy on or before that date.

     In January 2002, the ACC opened a "generic" docket to "determine if changed
circumstances require the [ACC] to take another look at electric restructuring
in Arizona." On June 17, 2002, hearings began on various issues ("Track A
Issues") in the consolidated docket. On July 23, 2002, an ACC ALJ issued a
recommended order on Track A Issues recommending, among other things, that our
ability to transfer our generation assets be stayed until at least July 1, 2004.
On August 1, 2002, we filed exceptions to the recommended order stating that it
is unreasonable and unlawful. The ACC will hold an open meeting on August 27,
2002 to consider Track A Issues. These matters are discussed in more detail
below.

                                       8

     1999 SETTLEMENT AGREEMENT. The following are the major provisions of the
1999 Settlement Agreement, as approved:

     *    We have reduced, and will reduce, rates for standard-offer service for
          customers with loads less than three MW in a series of annual retail
          electricity price reductions of 1.5% beginning July 1, 1999 through
          July 1, 2003, for a total of 7.5%. The first reduction of
          approximately $24 million ($14 million after income taxes) included a
          July 1, 1999 retail price decrease of approximately $11 million ($7
          million after income taxes) related to a 1996 regulatory agreement.
          Based on the price reductions authorized in the 1999 Settlement
          Agreement, there were also retail price decreases of approximately $28
          million ($17 million after taxes), or 1.5%, effective July 1, 2000;
          approximately $27 million ($16 million after taxes), or 1.5%,
          effective July 1, 2001; and approximately $28 million ($17 million
          after taxes), or 1.5%, effective July 1, 2002. For customers having
          loads of three MW or greater, standard-offer rates have been reduced
          in varying annual increments that total 5% in the years 1999 through
          2002.

     *    Unbundled rates being charged by us for competitive direct access
          service (for example, distribution services) became effective upon
          approval of the 1999 Settlement Agreement, retroactive to July 1,
          1999, and also became subject to annual reductions beginning January
          1, 2000, that vary by rate class, through January 1, 2004.

     *    There will be a moratorium on retail price changes for standard-offer
          and unbundled competitive direct access services until July 1, 2004,
          except for the price reductions described above and certain other
          limited circumstances. Neither the ACC nor we will be prevented from
          seeking or authorizing rate changes prior to July 1, 2004 in the event
          of conditions or circumstances that constitute an emergency, such as
          an inability to finance on reasonable terms; material changes in our
          cost of service for ACC-regulated services resulting from federal,
          tribal, state or local laws; regulatory requirements; or judicial
          decisions, actions or orders.

     *    We will be permitted to defer for later recovery prudent and
          reasonable costs of complying with the Rules, system benefits costs in
          excess of the levels included in then-current (1999) rates, and costs
          associated with the "provider of last resort" and standard-offer
          obligations for service after July 1, 2004. These costs are to be
          recovered through an adjustment clause or clauses commencing on July
          1, 2004.

     *    Our distribution system opened for retail access effective September
          24, 1999. Customers were eligible for retail access in accordance with
          the phase-in adopted by the ACC under the Rules (see "Retail Electric
          Competition Rules" below), including an additional 140 MW being made
          available to eligible non-residential customers. We opened our
          distribution system to retail access for all customers on January 1,
          2001.

     *    Prior to the 1999 Settlement Agreement, we were recovering
          substantially all of our regulatory assets through July 1, 2004,
          pursuant to a 1996 regulatory agreement. In addition, the 1999
          Settlement Agreement states that we have demonstrated that our

                                       9

          allowable stranded costs, after mitigation and exclusive of regulatory
          assets, are at least $533 million net present value. We will not be
          allowed to recover $183 million net present value of the above
          amounts. The 1999 Settlement Agreement provides that we will have the
          opportunity to recover $350 million net present value through a
          competitive transition charge that will remain in effect through
          December 31, 2004, at which time it will terminate. The costs subject
          to recovery under the adjustment clause described above will be
          decreased or increased by any over/under-recovery due to sales volume
          variances.

     *    We will form, or cause to be formed, a separate corporate affiliate or
          affiliates and transfer to such affiliate(s) our competitive electric
          assets and services at book value as of the date of transfer, and will
          complete the transfers no later than December 31, 2002. We will be
          allowed to defer and later collect, beginning July 1, 2004,
          sixty-seven percent of our costs to accomplish the required transfer
          of generation assets to an affiliate. Consistent with that
          requirement, we have been addressing the legal and regulatory
          requirements necessary to complete the transfer of our generation
          assets to Pinnacle West Energy on or before that date. However, as
          noted above and discussed in greater detail below, an ACC ALJ has
          recommended that our ability to transfer our generation assets be
          stayed until at least July 1, 2004.

     RETAIL ELECTRIC COMPETITION RULES. The Rules approved by the ACC include
the following major provisions:

     *    They apply to virtually all Arizona electric utilities regulated by
          the ACC, including us.

     *    Effective January 1, 2001, retail access became available to all our
          retail electricity customers.

     *    Electric service providers that get CC&N's from the ACC can supply
          only competitive services, including electric generation, but not
          electric transmission and distribution.

     *    Affected utilities must file ACC tariffs that unbundle rates for
          noncompetitive services.

     *    The ACC shall allow a reasonable opportunity for recovery of
          unmitigated stranded costs.

     *    Absent an ACC waiver, prior to January 1, 2001, each affected utility
          (except certain electric cooperatives) must transfer all competitive
          electric assets and services to an unaffiliated party or parties or to
          a separate corporate affiliate or affiliates. Under the 1999
          Settlement Agreement, we received a waiver to allow transfer of our
          competitive electric assets and services to affiliates no later than
          December 31, 2002.

                                      10

     Under the 1999 Settlement Agreement, the Rules are to be interpreted and
applied, to the greatest extent possible, in a manner consistent with the 1999
Settlement Agreement. If the two cannot be reconciled, we must seek, and the
other parties to the 1999 Settlement Agreement must support, a waiver of the
Rules in favor of the 1999 Settlement Agreement.

     On November 27, 2000, a Maricopa County, Arizona, Superior Court judge
issued a final judgment holding that the Rules are unconstitutional and unlawful
in their entirety due to failure to establish a fair value rate base for
competitive electric service providers and because certain of the Rules were not
submitted to the Arizona Attorney General for certification. The judgment also
invalidates all ACC orders authorizing competitive electric service providers to
operate in Arizona. We do not believe the ruling affects the 1999 Settlement
Agreement. The 1999 Settlement Agreement was not at issue in the consolidated
cases before the judge. Further, the ACC made findings related to the fair value
of our property in the order approving the 1999 Settlement Agreement. The ACC
and other parties aligned with the ACC have appealed the ruling to the Arizona
Court of Appeals, as a result of which the Superior Court's ruling is
automatically stayed pending further judicial review. In a similar appeal
concerning the issuance of competitive telecommunications CC&N's, the Arizona
Court of Appeals invalidated rates for competitive carriers due to the ACC's
failure to establish a fair value rate base for such carriers. That decision was
upheld by the Arizona Supreme Court.

     PROVIDER OF LAST RESORT OBLIGATION. Although the Rules allow retail
customers to have access to competitive providers of energy and energy services,
we are the "provider of last resort" for standard-offer, full-service customers
under rates that have been approved by the ACC. These rates are established
until July 1, 2004. The 1999 Settlement Agreement allows us to seek adjustment
of these rates in the event of emergency conditions or circumstances, such as
the inability to secure financing on reasonable terms; material changes in our
cost of service for ACC-regulated services resulting from federal, tribal, state
or local laws; regulatory requirements; or judicial decisions, actions or
orders. Energy prices in the western wholesale market vary and, during the
course of the last two years, have been volatile. At various times, prices in
the spot wholesale market have significantly exceeded the amount included in our
current retail rates. In the event of shortfalls due to unforeseen increases in
load demand or generation or transmission outages, we may need to purchase
additional supplemental power in the wholesale spot market. Unless we are able
to obtain an adjustment of our rates under the emergency provisions of the 1999
Settlement Agreement, there can be no assurance that we would be able to fully
recover the costs of this power.

     PROPOSED RULE VARIANCE AND PURCHASE POWER AGREEMENT. Commencing on the
transfer of the fossil-fueled generating assets and the receipt of certain
regulatory approvals, Pinnacle West Energy expects to sell its power at
wholesale to Pinnacle West's marketing and trading division, which, in turn, is
expected to sell power to us and to non-affiliated power purchasers. In a filing
with the ACC on October 18, 2001, we requested the ACC to:

     *    grant us a partial variance from an ACC Rule that would obligate us to
          acquire all of our customers' standard-offer, full-service generation

                                       11

          requirements from the competitive market (with at least 50% of those
          requirements coming from a "competitive bidding" process) starting in
          2003; and

     *    approve as just and reasonable a long-term purchase power agreement
          between us and Pinnacle West.

We requested these ACC actions to ensure ongoing reliable service to our
standard-offer, full-service customers in a volatile generation market and to
recognize Pinnacle West Energy's significant investment to serve our load.

     GENERIC DOCKET. In January 2002, the ACC opened a "generic" docket to
"determine if changed circumstances require the [ACC] to take another look at
electric restructuring in Arizona." In February 2002, the ACC docket relating to
our October 2001 filing was consolidated with several other pending ACC dockets,
including the generic docket. On April 19, 2002, we filed a motion in the
consolidated docket addressing the following issues, among others:

     *    We confirmed our position that whether or not the ACC approved the
          matters requested in our October 2001 filing, we would proceed with
          the divestiture of our generation assets by the end of 2002, as
          legally required.

     *    We also advised the ACC that whether or not the ACC approved the
          matters requested in our October 2001 filing, we would implement a
          competitive bidding process later in 2002 to the extent legally
          required.

     *    We noted that Pinnacle West Energy, the affiliate to which we intend
          to transfer the generation assets, had committed to an investment of
          approximately $1 billion in generating capacity to meet our customer
          needs in reliance on the 1999 Settlement Agreement. We further noted
          that we have taken numerous actions in reliance on the 1999 Settlement
          Agreement and the ACC Rules, including writing off $234 million before
          income taxes of prudently incurred costs, reducing retail rates in an
          ongoing series of rate reductions, and incurring tens of millions of
          dollars in expenses related to the expected generation asset transfer.
          We stated that if the ACC elects to reverse course on retail electric
          competition or attempts to stay the transfer of our generation assets,
          the ACC would be legally required to address just compensation to us
          and Pinnacle West Energy, which would include, at a minimum:

          *    recognizing the transfer to us of all assets that Pinnacle West
               Energy constructed to meet our load-serving requirements, and
               subsequently including such units in our rate base in accordance
               with traditional rate-of-return regulation;

          *    reversing our $234 million pre-tax write-off and providing for
               the recovery of such amounts in future rates; and

          *    providing for the recovery of all costs incurred as a result of
               the transition to competition, including 100 percent of the costs

                                       12

               incurred in preparation for divestiture (and not just the
               sixty-seven percent of costs permitted under the 1999 Settlement
               Agreement).

     *    We recommended that the ACC confirm whether or not Arizona would
          proceed with the transition to a competitive electric market, and
          proposed a procedural plan in response to issues identified by the ACC
          Staff in a previous report.

     On April 26, 2002, the ACC issued a procedural order in which the ACC
stayed the previously-scheduled April 29, 2002 hearing on the matters raised in
our October 2001 ACC filing (see "Proposed Rule Variance and Purchase Power
Agreement" above). On May 2, 2002, the ACC issued a procedural order stating
that hearings would begin on June 17, 2002 on various issues ("Track A Issues"),
including our planned divestiture of generation assets to Pinnacle West Energy
and associated market and affiliate issues.

     The procedural order also stated that consideration of the competitive
bidding process (the "Track B Issues") required by the Rules would proceed
concurrently with the Track A Issues. The objectives and process of the Track B
Issues would be determined in one or more meetings of affected parties with a
"target completion date" of October 21, 2002.

     On July 11, 2002, we filed a letter with the ACC discussing the
circumstances under which we could support a temporary suspension or stay of
certain Arizona electric competition rules. In our letter, we stated that we
could support a delay of the Rules' mandatory divestiture of generation assets
and competitive procurement requirements if:

     *    the ACC permits us to end the "bifurcation" of our generation
          resources as between ourselves and Pinnacle West Energy by authorizing
          the acquisition by us of the Pinnacle West Energy generating
          facilities constructed or being constructed to serve us;

     *    the ACC provides to us any additional debt financing authorization
          necessary to accomplish this acquisition; and

     *    while these assets remain with us serving retail customers, their
          inclusion in rates will be subject to ACC review as to their prudence
          and as to whether they are "used and useful" just as are our existing
          generating plants.

     On July 23, 2002 an ACC ALJ issued a recommended order on Track A Issues in
the consolidated docket. Among other things, the ALJ recommends that:

     *    our ability to transfer our generation assets be stayed until the ACC
          determines that the wholesale market is "workably competitive" and
          until at least July 1, 2004, at which time the ACC would reassess the
          appropriateness and timing of divestiture;

                                       13

     *    the current requirement that 100 percent of power purchased for
          standard-offer service be acquired from the competitive market, with
          at least 50 percent through a competitive bid process, be stayed
          indefinitely; and

     *    upon implementation of the outcome of the competitive bidding process
          ("Track B Issues"), we would acquire, at a minimum, any required power
          not produced by our owned generation through a competitive procurement
          process developed in the Track B proceeding.

     In addition, the ALJ recommended that if we wish to acquire certain
generation assets from Pinnacle West Energy, as discussed in our July 11, 2002
letter to the ACC, we should file appropriate applications on this matter for
ACC consideration.

     The ALJ also recommended that the ACC Staff open a rulemaking to review the
Rules in light of the other decisions in the recommended order and that an
Electric Competition Advisory Group be formed to facilitate communication among
the ACC Staff, stakeholders and market participants.

     On August 1, 2002, we filed exceptions to the recommended order, stating
that the recommended order, if adopted by the ACC, would be unreasonable and
unlawful because, among other reasons:

     *    the recommended order's prohibition on our transfer of generation
          assets to Pinnacle West Energy would unfairly harm us and Pinnacle
          West by bifurcating generation assets between us and Pinnacle West
          Energy, even though those assets are devoted to serving our customers;

     *    the recommended order's prohibition on our transfer of generation
          assets to Pinnacle West Energy would constitute a material breach of
          the 1999 Settlement Agreement, even though we have fulfilled our
          obligations under the 1999 Settlement Agreement, including writing off
          $234 million of otherwise recoverable costs, voluntarily reducing
          retail rates by some $600 million (to date), and dismissing with
          prejudice our pending litigation against the ACC;

     *    the recommended order does not discuss less onerous alternatives to
          breaching the 1999 Settlement Agreement, such as consideration of the
          Purchase Power Agreement proposed by us in our October 18, 2001 filing
          with the ACC or our acquisition of certain Pinnacle West Energy
          generation assets, as outlined in our July 11, 2002 letter to the ACC;

     *    the recommended order's finding that we have wholesale market power in
          certain Arizona geographical areas is not supported by the evidence
          or, at worst, the ACC should make no finding on the issue of market
          power; and

     *    the "generic proceedings" giving rise to the recommended order do not
          and have not complied with Arizona law as applicable to the amendment
          or rescission of the ACC order associated with the 1999 Settlement
          Agreement.

                                       14

     The ACC will hold an open meeting on August 27, 2002 to consider Track A
Issues.

     We cannot predict the outcome of the consolidated docket or its effect on
the existing Rules or the 1999 Settlement Agreement.

FEDERAL

     In June 2001, the FERC adopted a price mitigation plan that constrains the
price of electricity in the wholesale spot electricity market in the western
United States. The plan, which has a price cap of approximately $90 per MWh,
remains in effect until September 30, 2002. FERC has now adopted a final price
cap of $250 per MWh, which will become effective as of October 1, 2002.

     On July 31, 2002, the FERC issued a Notice of Proposed Rulemaking Standard
Market Design for wholesale electric markets. We are reviewing the proposed
rulemaking and cannot currently predict what, if any, impact there may be to the
Company if the FERC adopts the proposed rule.

GENERAL

     We cannot accurately predict the impact of full retail competition on our
financial position, cash flows, results of operations, or liquidity. As
competition in the electric industry continues to evolve, we will continue to
evaluate strategies and alternatives that will position us to compete in the new
regulatory environment.

6.   Nuclear Insurance

     The Palo Verde participants have insurance for public liability resulting
from nuclear energy hazards to the full limit of liability under federal law.
This potential liability is covered by primary liability insurance provided by
commercial insurance carriers in the amount of $200 million and the balance by
an industry-wide retrospective assessment program. If losses at any nuclear
power plant covered by the programs exceed the accumulated funds, we could be
assessed retrospective premium adjustments. The maximum assessment per reactor
under the program for each nuclear incident is approximately $88 million,
subject to an annual limit of $10 million per incident. Based upon our interest
in the three Palo Verde units, our maximum potential assessment per incident for
all three units is approximately $77 million, with an annual payment limitation
of approximately $9 million.

     The Palo Verde participants maintain "all risk" (including nuclear hazards)
insurance for property damage to, and decontamination of, property at Palo Verde
in the aggregate amount of $2.75 billion, a substantial portion of which must
first be applied to stabilization and decontamination. We have also secured
insurance against portions of any increased cost of generation or purchased
power and business interruption resulting from a sudden and unforeseen outage of
any of the three units. The insurance coverage discussed in this and the
previous paragraph is subject to certain policy conditions and exclusions.

                                       15

7.   Business Segments

     We have two principal business segments (determined by products, services
and the regulatory environment), which consist of our regulated retail
electricity business, regulated traditional wholesale electricity business, and
related activities (electric retail business segment) and our competitive
business activities (marketing and trading business segment). Our electric
retail business segment includes activities related to electricity transmission
and distribution, as well as electricity generation. Our marketing and trading
business segment includes activities related to wholesale marketing and trading.
During 2001, we transferred most of our marketing and trading activities,
including all related assets and liabilities, to Pinnacle West (see Note 14).
Financial data for the business segments follows (dollars in millions):

8.   Accounting Matters

     On January 1, 2002, we adopted SFAS No. 142, "Goodwill and Other Intangible
Assets." This statement addresses financial accounting and reporting for
acquired goodwill and other intangible assets and supersedes APB Opinion No. 17,
"Intangible Assets." We have no goodwill recorded and have separately disclosed
other intangible assets in our balance sheets. This new standard has no material
impact on our financial statements, and the required disclosures are provided in
Note 13.

     On January 1, 2002, we adopted SFAS No. 144, "Accounting for the Impairment
or Disposal of Long-Lived Assets." This statement supersedes SFAS No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed Of," and the accounting and reporting provisions for the disposal of
a segment of a business. This standard did not impact our financial statements
at adoption.

     In August 2001, the FASB issued SFAS No. 143, "Accounting for Asset
Retirement Obligations," which we will adopt January 1, 2003. The standard
requires the fair value of asset retirement obligations to be recorded as a
liability, along with an offsetting plant asset, when the obligation is
incurred. Accretion of the liability due to the passage of time will be an
operating expense and the capitalized cost will be depreciated over the useful
life of the long-lived asset.

                                       16

     We have not yet determined the impact of the new standard on our financial
statements. We determined that we have asset retirement obligations for our
nuclear facilities (nuclear decommissioning) and certain other fossil
generation, transmission, and distribution assets. Upon adoption, we will record
the retirement obligations and the related plant assets and accumulated
depreciation. The impact of these adjustments will likely be different than the
removal costs currently reflected in our financial statements for assets that
have an asset retirement obligation. For our non-regulated operations, the
impact of adopting this new standard will be reflected in earnings as a
cumulative effect of a change in accounting principle. We are currently
evaluating our ability to recover the transition costs and ongoing current
period costs of SFAS No. 143 in rates for our regulated operations. If such
costs are expected to be recoverable in rates, we would recognize a regulatory
asset or regulatory liability upon the adoption of SFAS No. 143 rather than a
cumulative effect adjustment to earnings.

     In April 2002, the FASB issued SFAS No. 145, "Rescission of FASB Statements
No. 4, 44, and 64, Amendment of FASB Statement No. 13, and Technical
Corrections" which supersedes previous guidance for reporting gains and losses
from extinguishment of debt and accounting for leases, among other things. The
portion of the statement relating to the early extinguishment of debt is
effective for us beginning in 2003. We do not believe the adoption of this
statement will have a material impact on our financial statements.

     In July 2002, the FASB issued SFAS No. 146, "Accounting for Costs
Associated with Exit or Disposal Activities." The standard requires companies to
recognize costs associated with exit or disposal activities when they are
incurred rather than at the date of a commitment to an exit or disposal plan.
The guidance should be applied prospectively to exit or disposal activities
initiated after December 31, 2002.

     In 2001, the American Institute of Certified Public Accountants issued an
exposure draft of a proposed Statement of Position, "Accounting for Certain
Costs Related to Property, Plant, and Equipment." This proposed Statement of
Position, which would be effective for us in 2004, would create a project
timeline framework for capitalizing costs related to property, plant and
equipment construction. It would require that property, plant and equipment
assets be accounted for at the component level, and require administrative and
general costs incurred in support of capital projects to be expensed in the
current period. The American Institute of Certified Public Accountants plans to
issue the final Statement of Position in the fourth quarter of 2002.

     In June 2002, the FASB's EITF finalized certain guidance related to energy
trading activities in EITF 02-3 "Accounting for Contracts Involved in Energy
Trading and Risk Management Activities." The new guidance, which is effective
July 1, 2002, requires that all energy trading activities within the scope of
EITF 98-10, "Accounting for Contracts Involved in Energy Trading and Risk
Management Activities," be presented on a net basis in revenues and that prior
period amounts should be restated to conform to the consensus. We will make this
presentation change in the third quarter of 2002. The impact on our marketing
and trading segment would result in equivalent decreases in revenues and
purchased power (gross margin would not be affected) for the three-, six-, and
twelve-month periods ended June 30, 2002 and 2001 as follows (dollars in
millions before income taxes):

9.   Off-Balance Sheet Financing

     In 1986, we entered into agreements with three separate SPE lessors in
order to sell and lease back interests in Palo Verde Unit 2. The leases are
accounted for as operating leases in accordance with GAAP. In July 2002, the
FASB issued an exposure draft related to SPEs. It is expected that the FASB will
issue final guidance on accounting for SPEs later this year with an immediate
effective date for newly-created entities and for all other entities as of the
beginning of the first fiscal period beginning April 1, 2003. We are currently
evaluating the impacts of the exposure draft and we may be required to
consolidate the Palo Verde SPEs in our financial statements. If consolidation
were required, the assets and liabilities of the SPEs that relate to the
sale-leaseback transactions would be reflected on our condensed balance sheet at
fair value. We are also evaluating the impact of including the related fair
value of assets and liabilities. The secured lease obligation bonds that are not
reflected on our condensed balance sheet at June 30, 2002 are approximately $285
million. The rating agencies have already considered this debt when evaluating
our credit ratings. This is our only significant off-balance sheet financing
activity.

10.  Derivative Instruments

     We are exposed to the impact of market fluctuations in the price and
transportation costs of electricity, natural gas, coal and emissions allowances.
We employ established procedures to manage risks associated with these market
fluctuations by utilizing various commodity derivatives, including
exchange-traded futures and options and over-the-counter forwards, options, and
swaps. As part of our overall risk management program, we enter into derivative
transactions to hedge purchases and sales of electricity, fuels, and emissions
allowances and credits. The changes in market value of such contracts have a
high correlation to price changes in the hedged commodity.

     Effective January 1, 2001, we adopted SFAS No. 133, "Accounting for
Derivative Instruments and Hedging Activities." SFAS No. 133 requires that
entities recognize all derivatives as either assets or liabilities on the
balance sheets and measure those instruments at fair value. Changes in the fair
value of derivative financial instruments are either recognized periodically in
income or shareholders' equity (as a component of other comprehensive income),
depending on whether or not the derivative meets specific hedge accounting
criteria. We use cash flow hedges to limit our exposure to cash flow variability
on forecasted transactions. Hedge effectiveness is related to the degree to
which the derivative contract and the hedged item are correlated. It is measured
based on the relative changes in fair value between the derivative contract and
the hedged item over time. We exclude the time value of certain options from our
assessment of hedge effectiveness. Any change in the fair value resulting from
ineffectiveness is recognized immediately in net income.

     On January 1, 2001, we recorded a $3 million after-tax loss in net income
and a $65 million after-tax gain in equity (as a component of other
comprehensive income), both as a cumulative effect of a change in accounting
principle. The gain resulted from unrealized gains on cash flow hedges.

                                       18

     In June 2001, the FASB issued new guidance related to electricity
contracts. The effective date of this new guidance was July 1, 2001. As of July
1, 2001, we recorded an additional $12 million after-tax loss in net income and
an additional $8 million after-tax gain in equity (as a component of other
comprehensive income), as a result of adopting the new guidance related to
electricity contracts. The loss resulted primarily from electricity options
contracts. The gain resulted from unrealized gains on cash flow hedges. The
impact of the new guidance is reflected in net income and other comprehensive
income as a cumulative effect of a change in accounting principle.

     In December 2001, the FASB issued revised guidance on the accounting for
electricity contracts with option characteristics and the accounting for
contracts that combine a forward contract and a purchased option contract. The
effective date for the revised guidance was April 1, 2002. The impact of this
guidance was immaterial to our financial statements.

     The change in derivative fair value included in the condensed statements of
income for the three, six and twelve months ended June 30, 2002 and 2001 are
comprised of the following (dollars in thousands):

     As of June 30, 2002, the maximum length of time over which we are hedging
our exposure to the variability in future cash flows for forecasted transactions
is thirty months. During the twelve months ending June 30, 2003, we estimate
that a net loss of $16 million before income taxes will be reclassified from
accumulated other comprehensive loss as an offset to the effect on earnings of
market price changes for the related hedged transactions.

12.  Commitments and Contingencies

California Energy Market Issues and Refunds in the Pacific Northwest

     In July 2001, the FERC ordered an expedited fact-finding hearing to
calculate refunds for spot market transactions in California during a specified
time frame. This order calls for a hearing, with findings of fact due to the
FERC after the ISO and PX provide necessary historical data. The FERC also
ordered an evidentiary proceeding to discuss and evaluate possible refunds for
the Pacific Northwest. The administrative law judge at the FERC in charge of
that evidentiary proceeding made an initial finding that no refunds were
appropriate. The Pacific Northwest issues will now be addressed by the FERC
Commissioners. Although the FERC has not yet made a final ruling in the Pacific
Northwest matter or calculated the specific refund amounts due in California, we
do not expect that the resolution of these issues, as to the amounts alleged in
the proceedings, will have a material adverse impact on our financial position,
results of operations or liquidity.

     SCE and PG&E have publicly disclosed that their liquidity has been
materially and adversely affected because of, among other things, their
inability to pass on to ratepayers the prices each has paid for energy and
ancillary services procured through the PX and the ISO. PG&E filed for
bankruptcy protection in 2001.

     We are closely monitoring developments in the California energy market and
the potential impact of these developments on us. We have evaluated, among other
things, SCE's role as a Palo Verde and Four Corners participant; our
transactions with the PX and the ISO; contractual relationships with SCE and
PG&E; and marketing and trading exposures. Based on our evaluations, we do not
believe the foregoing matters will have a material adverse affect on our
financial position and liquidity. We cannot predict with certainty, however, the
impact that any future resolution or attempted resolution, of the California
energy market situation may have on us or the regional energy market in general.

     CALIFORNIA ENERGY MARKET LITIGATION. On March 19, 2002, the State of
California filed a complaint with the FERC alleging that wholesale sellers of
power and energy, including Pinnacle West, failed to properly file rate
information at the FERC in connection with sales to California from 2000 to the
present. STATE OF CALIFORNIA V. BRITISH COLUMBIA POWER EXCHANGE ET. AL., Docket
No. EL02-71-000. The complaint requests the FERC to require the wholesale
sellers to refund any rates that are "found to exceed just and reasonable
levels." This complaint has been dismissed by FERC. In addition, the State of
California and others have filed various claims, which have now been
consolidated, against several power suppliers to California alleging antitrust
violations. WHOLESALE ELECTRICITY ANTITRUST CASES I AND II, Superior Court in
and for the County of San Diego, Proceedings Nos. 4204-00005 and 4204-00006. Two
of the suppliers who were named as defendants in those matters, Reliant Energy
Services, Inc. (and other Reliant entities) and Duke Energy and Trading, LLP
(and other Duke entities), filed cross-claims against various other participants
in the California PX and ISO markets, including us, attempting to expand those
matters to such other participants. We have not yet filed a responsive pleading
in the matter, but we believe the claims by Reliant and Duke as they relate to
us are without merit.

     We were also named in a lawsuit regarding wholesale contracts in
California. JAMES MILLAR, ET AL. V. ALLEGHENY ENERGY SUPPLY, ET AL., United
States District Court in and for the District of Northern California, Case No.

                                       21

C02-2855 EMC. The complaint alleges basically that the contracts entered into
were the result of an unfair and unreasonable market. The California PX has
filed a lawsuit against the State of California regarding the seizure of forward
contracts and the State has filed a cross complaint against us. CAL PX V. THE
STATE OF CALIFORNIA Superior Court in and for the County of Sacramento, JCCP No.
4203. Various preliminary motions are being filed and we cannot currently
predict the outcome of this matter. The "United States Justice Foundation" is
suing numerous wholesale energy contract suppliers to California, including
Pinnacle West, as well as the California Department of Water Resources, based
upon an alleged conflict of interest arising from the activities of a consultant
for Edison International who also negotiated long-term contracts for the
California Department of Water Resources. MCCLINTOCK, ET AL. V. YUDHRAJA,
Superior Court in and for the County of Los Angeles, Case No. GC 029447. The
California Attorney General has indicated that an investigation by his office
did not find evidence of improper conduct by the consultant. We believe the
claims against us in the lawsuits mentioned in this paragraph are without merit
and will have no material adverse impact on our financial position, results of
operations or liquidity.

Power Service Agreement

     By letter dated March 7, 2001, Citizens, which owns a utility in Arizona,
advised us that it believes we have overcharged Citizens by over $50 million
under a power service agreement. We believe that our charges under the agreement
were fully in accordance with the terms of the agreement. In addition, in
testimony filed with the ACC on March 13, 2002, Citizens acknowledged that,
based on its review, "if Citizens filed a complaint with FERC, it probably would
lose the central issue in the contract interpretation dispute." We terminated
the power service agreement with Citizens effective July 15, 2001. In
replacement of the power service agreement, Pinnacle West and Citizens entered
into a power sale agreement under which Pinnacle West will supply Citizens with
specified amounts of electricity and ancillary services through May 31, 2008.
This new agreement does not address issues previously raised by Citizens with
respect to charges under the original power service agreement through June 1,
2001.

13.  Intangible Assets

     On January 1, 2002, we adopted SFAS No. 142, "Goodwill and Other Intangible
Assets." This statement addresses financial accounting and reporting for
acquired goodwill and other intangible assets and supersedes APB Opinion No. 17,
"Intangible Assets." The Company's gross intangible assets (which are primarily
software) were $185 million at June 30, 2002 and $170 million at December 31,
2001. The related accumulated amortization was $95 million at June 30, 2002 and
$87 million at December 31, 2001. Amortization expense for the three-month
period ended June 30 was $5 million in 2002 and 2001. Amortization expense for
the six-month period ended June 30 was $9 million in 2002 and $10 million in
2001. Amortization expense for the twelve-month period ended June 30 was $20
million in 2002 and $21 million in 2001. Estimated amortization expense on
existing intangible assets over the next five years is $16 million in 2002, $14
million in 2003, $14 million in 2004, $12 million in 2005 and $11 million in
2006.

                                       22

14.  Related Party Transactions

During 2001, we transferred most of our marketing and trading activities to
Pinnacle West, which approximated $219 million in assets and $149 million in
liabilities. From time to time, we enter into transactions with Pinnacle West or
Pinnacle West's subsidiaries. The following table summarizes the amounts
included in the income statements and balance sheets related to transactions
with affiliated companies (dollars in millions):

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS.

INTRODUCTION

     In this section, we explain our results of operations, general financial
condition, and outlook including:

     *    the changes in our earnings for the three, six and twelve months ended
          June 30, 2002 and 2001;

     *    the effects of regulatory agreements and developments on our results
          and outlook;

     *    our capital needs, liquidity and capital resources;

     *    our business outlook; and

     *    our management of market risks.

     We suggest this section be read along with the 2001 10-K. Throughout this
Management's Discussion and Analysis of Financial Condition and Results of
Operations, we refer to specific "Notes" in the Notes to Condensed Financial
Statements in this report. These Notes add further details to the discussion.

OVERVIEW OF OUR BUSINESS

     We are an electric utility that provides either retail or wholesale
electric service to substantially all of the state of Arizona, with the major
exceptions of the Tucson metropolitan area and about one-half of the Phoenix
metropolitan area. Electricity is provided through a distribution system owned
by us. We also generate and, through Pinnacle West's marketing and trading
division, sell and deliver electricity to wholesale customers in the western
United States. Pinnacle West owns all of our outstanding stock.

     We are required to transfer our competitive electric assets and services to
one or more corporate affiliates no later than December 31, 2002. Consistent
with that requirement, we have been addressing the legal and regulatory
requirements necessary to complete the transfer of our generation assets to
Pinnacle West Energy before that date. As we discuss in greater detail in Note
5, on July 23, 2002, an ACC ALJ issued a recommended order recommending, among
other things, that our ability to transfer our generation assets be stayed until
at least July 1, 2004.

BUSINESS SEGMENTS

     We have two principal business segments (determined by products, services
and the regulatory environment), which consist of our regulated retail
electricity business, regulated traditional wholesale electricity business, and

                                       25

related activities (electric retail business segment) and our competitive
business activities (marketing and trading business segment). Our electric
retail business segment includes activities related to electricity transmission
and distribution, as well as electricity generation. Our marketing and trading
business segment includes activities related to wholesale marketing and trading.
During 2001, we transferred most of our marketing and trading activities to
Pinnacle West (see Note 14).

     The following table summarizes net income by business segment for the
three, six and twelve months ended June 30, 2002 and the comparable prior year
periods (dollars in millions, unaudited):

Derivative Instruments and Hedging Activities."

EARNINGS VARIANCE EXPLANATIONS

     Throughout these explanations, we refer to "gross margin." With respect to
our electric retail segment and marketing and trading segment, gross margin
refers to electric operating revenues less purchased power and fuel costs.

OPERATING RESULTS - THREE-MONTH PERIOD ENDED JUNE 30, 2002 COMPARED WITH
THREE-MONTH PERIOD ENDED JUNE 30, 2001

     Our net income for the three months ended June 30, 2002 was $64 million
compared with $70 million for the same period in the prior year. The
period-to-period decrease was primarily the result of our transfer of marketing
and trading activities to Pinnacle West in 2001, substantially offset by higher
retail earnings. The retail comparison was favorably impacted by lower
replacement costs for power plant outages, lower costs for purchased power and
gas related to lower market prices, customer growth and higher average usage per
customer, partially offset by the effects of milder weather. Also, there was
lower other income, partially offset by decreased depreciation and amortization
expense.

Electric Retail Segment Gross Margin

     Revenues related to our regulated retail and wholesale electricity
businesses were $232 million lower in the three-month period ended June 30,
2002, compared to the same period in the prior year as a result of:

     *    decreased revenues related to traditional wholesale sales as a result
          of lower sales volumes and lower prices ($54 million);
     *    decreased revenues related to retail load hedge management wholesale
          sales, as a result of lower sales volumes and lower prices ($167
          million);

                                       27

     *    decreased retail revenues related to milder weather ($26 million);
     *    increased retail revenues related to customer growth and higher
          average usage, excluding weather effects ($21 million);
     *    decreased retail revenues related to a reduction in retail electricity
          prices ($7 million); and
     *    other miscellaneous factors ($1 million net increase).

     Electric retail segment purchased power and fuel costs were $328 million
lower in the three-month period ended June 30, 2002, compared to the same period
in the prior year as a result of:

     *    decreased costs related to traditional wholesale sales as a result of
          lower sales volumes and lower prices ($54 million);
     *    decreased replacement power costs for power plant outages due to lower
          market prices and fewer unplanned outages ($58 million);
     *    decreased costs related to lower prices for hedged natural gas and
          purchased power ($207 million);
     *    decreased costs related to the effects of milder weather on retail
          sales ($10 million);
     *    increased costs related to retail sales growth, excluding weather
          effects ($9 million);
     *    lower purchased power costs related to 2001 generation reliability
          program ($6 million); and
     *    other miscellaneous factors ($2 million net decrease).

Marketing and Trading Segment Gross Margin

     Marketing and trading segment revenues were $320 million lower in the
three-month period ended June 30, 2002, compared to the same period in the prior
year. The marketing and trading segment purchased power and fuel costs were $226
million lower in the three-month period ended June 30, 2002, compared to the
same period in the prior year. The lower marketing and trading segment revenues
and purchased power and fuel costs are a result of our transfer of marketing
and trading activities to Pinnacle West in 2001.

     The increase in operations and maintenance expense of $2 million was due to
increased overhaul expense and higher employee and other costs partially offset
by lower costs related to generation reliability, plant outages and maintenance
costs.

     The decrease in depreciation and amortization expense of $5 million
primarily related to lower regulatory asset amortization, in accordance with the
1999 regulatory settlement, partially offset by increased depreciation on higher
plant balances.

     Other income decreased $12 million primarily due to an insurance recovery
recorded in the prior period related to environmental remediation costs.

OPERATING RESULTS - SIX-MONTH PERIOD ENDED JUNE 30, 2002 COMPARED WITH SIX-MONTH
PERIOD ENDED JUNE 30, 2001

     Our net income for the six months ended June 30, 2002 was $96 million
compared with $131 million for the same period in the prior year. We recognized
a $3 million after-tax loss in the six months ended June 30, 2001 as a
cumulative effect of a change in accounting for derivatives, as required by SFAS
No.133.

     Our income before accounting change for the six months ended June 30, 2002
was $96 million compared with $134 million for the same period a year earlier.
The period-to-period decrease was the result of reduced marketing and trading
gross margin due to our transfer of marketing and trading activities to Pinnacle
West in 2001. The reduced marketing and trading gross margin was partially
offset by increased earnings contributions from our regulated retail electricity
operations. The retail comparison was favorably impacted by lower replacement
costs for power plant outages, lower costs for purchased power and gas related
to lower market prices, customer growth and higher average usage per customer,
partially offset by the effects of milder weather and a retail electricity price
decrease.

Marketing and Trading Segment Gross Margin

     Marketing and trading segment revenues were $661 million lower in the

year. Marketing and trading segment purchased power and fuel costs were $466
million lower in the six-month period ended June 30, 2002, compared to the same
period in the prior year. The lower marketing and trading segment revenues and
purchased power and fuel costs are a result of our transfer of marketing and
trading activities to Pinnacle West in 2001.

     The decrease in operations and maintenance expense of $3 million was
primarily due to lower costs related to generation reliability, plant outages
and maintenance costs. This decrease was partially offset by increased employee
benefit and other costs.

     The decrease in depreciation and amortization expense of $11 million
primarily related to lower regulatory asset amortization, in accordance with the
1999 regulatory settlement, partially offset by increased depreciation on higher
plant balances.

     Other income decreased $9 million primarily due to an insurance recovery
recorded in the prior period related to environmental remediation costs
partially offset by net investment gains in the current period.

OPERATING RESULTS - TWELVE-MONTH PERIOD ENDED JUNE 30, 2002 COMPARED WITH

     Our net income for the twelve months ended June 30, 2002 was $230 million
compared with $309 million for the same period in the prior year. We recognized
a $12 million after-tax loss in the twelve months ended June 30, 2002 and a $3
million after-tax loss in the twelve months ended June 30, 2001 as cumulative
effects of a change in accounting for derivatives, as required by SFAS No.133.

     Our income before accounting change for the twelve months ended June 30,
2002 was $242 million compared with $312 million for the same period a year
earlier. The period-to-period decrease is the result of our transfer of
marketing and trading activities to Pinnacle West by the end of 2001 and lower
earnings contributions from our marketing and trading activities. The comparison
for marketing and trading activities reflects lower volumes and prices in the
wholesale power markets in the western United States. These negative factors
were partially offset by increased earnings contributions from our regulated
retail electricity operations and lower depreciation and amortization costs. The
retail comparison was favorably impacted by lower replacement costs for power
plant outages, lower costs for purchased power and gas related to lower market
prices, customer growth and higher average usage per customer, partially offset
by higher purchased power costs related to our 2001 generation reliability
program, the effects of milder weather and a retail electricity price decrease.

Electric Retail Segment Gross Margin

     Revenues related to our regulated retail and wholesale electricity
businesses were $463 million lower in the twelve-month period ended June 30,
2002, compared to the same period in the prior year as a result of:

     *    decreased revenues related to traditional wholesale sales as a result
          of lower sales volumes and lower prices ($177 million);
     *    decreased revenues related to wholesale sales, as a result of lower
          sales volumes and lower prices ($293 million);
     *    increased retail revenues related to customer growth and higher
          average usage, excluding weather effects ($44 million);
     *    decreased retail revenues related to milder weather ($14 million);
     *    decreased retail revenues related to a reduction in retail electricity
          prices ($28 million); and
     *    other miscellaneous factors ($5 million net increase).

     Electric retail segment purchased power and fuel costs were $560 million
lower in the twelve-month period ended June 30, 2002, compared to the same
period in the prior year as a result of:

     *    decreased costs related to traditional wholesale sales as a result of
          lower sales volumes and lower prices ($177 million);
     *    decreased replacement power costs for power plant outages due to lower
          market prices and fewer unplanned outages ($126 million);
     *    decreased costs related to lower prices for hedged natural gas and
          purchased power prices ($285 million);
     *    increased costs related to retail sales growth, excluding weather
          effects ($17 million);
     *    decreased costs related to the effects of milder weather on retail
          sales ($5 million);
     *    higher purchased power costs related to 2001 generation reliability
          programs ($19 million); and
     *    miscellaneous factors ($3 million net decrease).

Marketing and Trading Segment Gross Margin

     Marketing and trading segment revenues were $1.29 billion lower in the
twelve-month period ended June 30, 2002, compared to the same period in the
prior year as a result of:

     *    decreased revenues related to our transfer of marketing and trading
          activities to Pinnacle West at the end of 2001 ($661 million);
     *    decreased revenues from generation sales other than native load due to
          lower market prices and resulting lower sales volumes ($84 million);

                                       34

     *    decreased revenues from other realized marketing and trading in the
          current period primarily due to lower prices on higher volumes ($564
          million);
     *    change in prior period mark-to-market gains on contracts delivered
          during the current period due to higher volumes being delivered ($25
          million increase); and
     *    lower mark-to-market gains for future period deliveries primarily as a
          result of greater market liquidity and greater price volatility,
          resulting in higher volumes ($6 million).

     Marketing and trading segment purchased power and fuel costs were $1.07
billion lower in the twelve-month period ended June 30, 2002, compared to the
same period in the prior year as a result of:

     *    decreased purchased power and fuel costs as a result of our transfer
          of marketing and trading activities to Pinnacle West at the end of
          2001 ($466 million);
     *    decreased fuel costs related to generation sales other than native
          load primarily because of lower sales volumes and lower natural gas
          prices ($43 million);
     *    decreased purchased power costs related to other realized marketing
          and trading in the current period primarily due to lower prices on
          higher volumes ($565 million);
     *    change in prior period mark-to-market fuel costs for current period
          deliveries related to accounting for derivatives ($2 million
          increase); and
     *    change in mark-to-market fuel costs for future period deliveries ($2
          million decrease).

     The increase in operations and maintenance expense of $9 million was
primarily related to the reversal of an environmental reserve in the fourth
quarter of 2000 and increased employee benefit and other costs.

     The decrease in depreciation and amortization expenses of $16 million
primarily related to lower regulatory asset amortization, in accordance with the
1999 regulatory settlement, partially offset by increased depreciation on higher
plant balances.

     Other expense decreased $6 million primarily due to the effects of losses
on other investments in prior periods.

     Other income decreased $9 million primarily due to the effects of an
insurance recovery recorded in the prior period related to environmental
remediation costs.

     Net interest expense decreased $8 million primarily because of the increase
in capitalized interest and the effects of lower interest rates. These
reductions in net interest expense more than offset the increase in interest
expense on higher debt balances.

                                ========   ========    ========    ========

(a)  Pursuant to the 1999 Settlement Agreement, we are required to transfer our
     competitive electric assets and services no later than December 31, 2002.
     As we discuss in greater detail in Note 5, on July 23, 2002, an ACC ALJ
     issued a recommended order recommending, among other things, that our
     ability to transfer our generation assets be stayed until at least July 1,
     2004. If the transfer of our generation assets is stayed, we expect our
     existing generation capital expenditures to be $116 million in 2003 and $89
     million in 2004, resulting in total capital expenditures for those years of
     $386 million and $356 million, respectively.

     Several years ago, we and the other Palo Verde participants decided to
replace Unit 2 steam generators, which replacement is presently scheduled to be
completed in the fall of 2003. We and the other Palo Verde participants are
currently considering issues related to replacement of the steam generators in
Units 1 and 3. Although a final determination of whether Units 1 and 3 will
require steam generator replacement to operate over their current full licensed
lives has not yet been made, we and the other participants have approved
fabrication of one set of spare steam generators. Our portion of this
expenditure is approximately $27 million, which will be spent from 2002 to 2005.
The capital expenditures table above includes $7 million of these costs in 2002.
If the Palo Verde participants decide to proceed with steam generator
replacement at both Units 1 and 3, we have estimated that our portion of the
fabrication and installation costs and associated power uprate modifications
would be approximately $130 million over the next seven years, which would be
funded with internally-generated cash or external financings. If our generation
assets are not transferred prior to this time, we will make these expenditures.

     Existing generation capital expenditures are comprised of multiple
improvements for our existing fossil and nuclear plants. Examples of the types
of projects included in this category are additions, upgrades and capital
replacements of various power plant equipment such as turbines, boilers, and
environmental equipment. The existing generation also contains nuclear fuel
expenditures of approximately $30 million only in 2002. We would make similar
nuclear fuel expenditures in 2003 and 2004 if our nuclear generation assets are
not transferred before those dates. Those expenitures are included in the
additional capital expenditures referenced in Note (a) to the capital
expenditure table.

                                       36

     Delivery capital expenditures are comprised of T&D infrastructure additions
and upgrades, capital replacements, new customer construction, and related
information systems and facility costs. Examples of the types of projects
included in the forecast include T&D lines and substations, line extensions to
new residential and commercial developments, and upgrades to customer
information systems. In addition, we began several major transmission projects
in 2001. These projects are periodic in nature and are driven by strong regional
customer growth. We expect to spend about $150 million on major transmission
projects during the 2002-2004 time frame.

(a)  Total cash commitments are approximately $4.1 billion. The total net
     present value of these cash commitments is $2.2 billion.

     Our significant debt covenants related to our financing arrangements
include a debt to total capitalization ratio and interest coverage test. We are
in compliance with such convenants and we anticipate that we will continue to
meet all the significant covenant requirement levels. The repercussions of not
meeting the covenants would result in an event of default which, generally
speaking, would require the immediate repayment of the debt subject to the
covenants. All of our bank agreements have cross-default provisions.

     Our cash requirements and our ability to fund those requirements are
discussed under "Capital Needs and Resources" in Management's Discussion and
Analysis of Financial Condition and Results of Operation in Part II, Item 7 of
the 2001 10-K.

     On March 1, 2002, we issued $375 million of 6.50% Notes due 2012.

     On April 15, 2002, we redeemed $122 million of our First Mortgage Bonds,
8.75% Series due 2024. On March 15, 2002, we redeemed at maturity $125 million
of our First Mortgage Bonds, 8.125% Series due 2002. See the cash commitments
table above for our debt repayments. Based on market conditions and optional
call provisions, we may make optional redemptions of long-term debt from time to
time.

                                       37

     Although provisions in our first mortgage bond indenture, articles of
incorporation, and ACC financing orders establish maximum amounts of additional
first mortgage bonds and preferred stock that we may issue, we do not expect any
of these provisions to limit our ability to meet its capital requirements.

CRITICAL ACCOUNTING POLICIES

     In preparing the financial statements in accordance with GAAP, management
must often make estimates and assumptions that affect the reported amounts of
assets, liabilities, revenues, expenses, and related disclosures at the date of
the financial statements and during the reporting period. Some of those
judgments can be subjective and complex, and actual results could differ from
those estimates. Our most critical accounting policies include the determination
of the appropriate accounting for our derivative instruments, mark-to-market
accounting and the impacts of regulatory accounting on our financial statements.
See Note 1 in the 2001 10-K. There have been no material changes since the 2001
10-K.

BUSINESS OUTLOOK

     For 2001, our reported income before accounting change was $281 million and
included charges totaling $13 million before income taxes that we do not expect
to recur related to our exposure to Enron and its affiliates. Our earnings have
been negatively affected by the transfer of most of our marketing and trading
activities to Pinnacle West in 2001, as well as retail electricity price
decreases. These negative factors are expected to be significantly offset in
2002 by the absence of significant expenses for reliability and power plant
outages that we incurred in 2001 that we do not expect to recur in 2002 and by
retail customer growth, although the pace of growth is expected to be slower
than in the past. These factors are described in more detail below.

     During 2001, in order to meet the highest customer demand in our history,
we incurred significant expenses for our summer reliability program and for
higher replacement power costs related to power plant outages. These efforts,
which cost approximately $140 million before income taxes, are not expected to
be repeated in 2002.

     In July 2002, Pinnacle West announced cost-containment measures that
include a voluntary workforce reduction of 500-600 positions. These reductions
would be implemented in the second half of 2002 and are expected to produce
annual operating expense savings at the parent of $30-35 million beginning in
2003, and a comparable one-time charge to its earnings later in 2002.

     We estimate our retail customer growth in 2002 to be 3.2%, which is slower
than the pace of growth in recent years, although still about three times the
national average. Our customer growth in 2001 was 3.7%. Our current estimate for
customer growth in 2003 and 2004 is between 3.5% and 4.0% annually.

                                       38

     The foregoing discussion of future expectations is forward-looking
information. Actual results may differ materially from expectations. See
"Forward-Looking Statements" below.

     COMPETITION AND ELECTRIC INDUSTRY RESTRUCTURING

     See "Business Outlook - Competition and Industry Restructuring" in Item 7
of the 2001 10-K and Note 5 above for a discussion of developments affecting
retail and wholesale electric competition.

     FACTORS AFFECTING OPERATING REVENUES

     Electric operating revenues are derived from sales of electricity in
regulated retail markets in Arizona, and from competitive retail and wholesale
bulk power markets in the western United States. These revenues are expected to
be affected by electricity sales volumes related to customer mix, customer
growth and average usage per customer, as well as electricity prices and
variations in weather from period to period.

     In our regulated retail market area, we will provide electricity services
to standard-offer, full-service customers and to energy delivery customers who
have chosen another provider for their electricity commodity needs (unbundled
customers). Customer growth in our service territory averaged about 4% a year
for the three years 1999 through 2001; we currently expect customer growth to be
about 3.2% in 2002 and between 3.5% and 4.0% a year in 2003 and 2004. We
currently estimate that retail electricity sales in kilowatt-hours will grow
3.5% to 5.5% a year in 2002 through 2004, before the retail effects of weather
variations. The customer growth and sales growth referred to in this paragraph
apply to energy delivery customers. As industry restructuring evolves in the
regulated market area, we cannot predict the number of our standard-offer
customers that will switch to unbundled service. As previously noted, under the
1999 Settlement Agreement, we agreed to retail electricity price reductions of
1.5% annually through July 1, 2003 (see Note 5).

     OTHER FACTORS AFFECTING FUTURE FINANCIAL RESULTS

     As we discuss in greater detail in Note 5, on July 23, 2002, an ACC ALJ
issued a recommended order recommending, among other things, that our ability to
transfer our generating assets be stayed until at least July 1, 2004. Pinnacle
West has financed Pinnacle West Energy's generation expansion program premised
upon Pinnacle West Energy's receipt of our generation assets by the end of 2002,
as promised by the 1999 Settlement Agreement. Pinnacle West Energy has
previously received investment grade credit ratings contingent upon its
acquisition of our generation assets. If we are prohibited from transferring our
generation assets to Pinnacle West Energy, Pinnacle West believes that if
Pinnacle West Energy is able to finance its capital requirements (including the
repayment of the bridge financing provided by Pinnacle West), it would only be
able to do so on commercially unattractive terms. In such a case, Pinnacle
West's overall financing costs could increase. As we discuss in Note 5, we have
proposed that we be permitted to acquire certain of Pinnacle West Energy's
generating facilities if the ACC prohibits or delays our transfer of generation
assets to Pinnacle West Energy. If we were to acquire Pinnacle West Energy
generation assets, we believe that we could obtain financing for those assets

                                       39

and could do so on terms more favorable than those that would be otherwise
available to Pinnacle West Energy.

     Purchased power and fuel costs are impacted by our electricity sales
volumes, existing contracts for generation fuel and purchased power, our power
plant performance, prevailing market prices, new generating plants being placed
in service and our hedging program for managing such costs.

     Operations and maintenance expenses are expected to be affected by sales
mix and volumes, power plant operations, inflation, outages and other factors.
See "Business Outlook" above for information regarding Pinnacle West
cost-containment measures announced in July 2002.

     Depreciation and amortization expenses are expected to be affected by net
additions to existing utility plant and other property, and changes in
regulatory asset amortization.

     Taxes other than income taxes consist primarily of property taxes, which
are affected by tax rates and the value of property in service and under
construction. The average property tax rate for us was 9.32% of assessed value
for 2001 and 9.16% for 2000. We expect property taxes to increase primarily due
to our additions to existing facilities.

     Interest expense is affected by the amount of debt outstanding and the
interest rates on that debt. The primary factor affecting borrowing levels in
the next several years is expected to be our internally-generated cash flow.
Capitalized interest offsets a portion of interest expense while capital
projects are under construction. We stop recording capitalized interest on a
project when it is placed in commercial operation.

     We cannot accurately predict the impact of full retail competition on our
financial position, cash flows, results of operations, or liquidity. As
competition in the electric industry continues to evolve, we will continue to
evaluate strategies and alternatives that will position us to compete
effectively in a restructured industry.

     Our financial results may be affected by the application of SFAS No. 133.
See Note 10 for further information.

     Our financial results may be affected by a number of broad factors. See
"Forward-Looking Statements" below for further information on such factors,
which may cause our actual future results to differ from those we currently seek
or anticipate.

RATE MATTERS

     See Note 5 for a discussion of a price reduction effective as of July 1,
2002, and for a discussion of the 1999 Settlement Agreement that will, among
other things, result in five annual price reductions over a four-year period
ending July 1, 2003.

                                       40

FORWARD-LOOKING STATEMENTS

     The above discussion contains forward-looking statements based on current
expectations and we assume no obligation to update these statements, except as
required by applicable laws. Because actual results may differ materially from
expectations, we caution readers not to place undue reliance on these
statements. A number of factors could cause future results to differ materially
from historical results, or from results or outcomes currently expected or
sought by us. These factors include the ongoing restructuring of the electric
industry, including the introduction of retail electric competition in Arizona;
the outcome of regulatory and legislative proceedings relating to the
restructuring; state and federal regulatory and legislative decisions and
actions, including the price mitigation plan adopted by the FERC; regional
economic and market conditions, including the California energy situation and
completion of generation construction in the region, which could affect customer
growth and the cost of power supplies; the cost of debt and equity capital;
weather variations affecting local and regional customer energy usage;
conservation programs; power plant performance; regulatory issues associated
with generation expansion, such as permitting and licensing; our ability to
compete successfully outside traditional regulated markets (including the
wholesale market); and technological developments in the electric industry.

     These factors and the other matters discussed above may cause future
results to differ materially from historical results, or from results or
outcomes we currently expect or seek.

ITEM 3. MARKET RISKS

     Our operations include managing market risks related to changes in interest
rates, commodity prices, and investments held by our nuclear decommissioning
trust fund.

     We are exposed to the impact of market fluctuations in the price and
transportation costs of electricity, natural gas, coal, and emissions
allowances. We employ established procedures to manage risks associated with
these market fluctuations by utilizing various commodity derivatives, including
exchange-traded futures and options and over-the-counter forwards, options, and
swaps. As part of our overall risk management program, we enter into derivative
transactions to hedge purchases and sales of electricity, fuels, and emissions
allowances and credits. The changes in market value of such contracts have a
high correlation to price changes in the hedged commodity.

     In 2001, subject to specified risk parameters established by Pinnacle
West's Board of Directors and monitored by Pinnacle West's Energy Risk
Management Committee, we engaged in trading activities intended to profit from
market price movements. In accordance with EITF 98-10, "Accounting For Contracts
Involved in Energy Trading and Risk Management Activities," such trading
positions are marked-to-market. These trading activities are part of our
marketing and trading activities and are reflected in the marketing and trading
segment revenues and expenses.

     As of June 30, 2002, a hypothetical adverse price movement of 10% in the
market price of our risk management and trading assets and liabilities would
have decreased the fair market value of these contracts by approximately $16
million. A hypothetical favorable price movement of 10% would have increased the
fair market value of these contracts by approximately $18 million.

                                       41

     We are exposed to losses in the event of nonperformance or nonpayment by
counterparties. We use a risk management process to assess and monitor the
financial exposure of this and all other counterparties. Despite the fact that
the great majority of trading counterparties are rated as investment grade by
the credit rating agencies, there is still a possibility that one or more of
these companies could default, resulting in a material impact on earnings for a
given period. Counterparties in the portfolio consist principally of major
energy companies, municipalities, and local distribution companies. We maintain
credit policies that we believe minimize overall credit risk to within
acceptable limits. Determination of the credit quality of our counterparties is
based upon a number of factors, including credit ratings and our evaluation of
their financial condition. In many contracts, we employ collateral requirements
and standardized agreements that allow for the netting of positive and negative
exposures associated with a single counterparty. Valuation adjustments are
established representing our estimated credit losses on our overall exposure to
counterparties.

     Changing interest rates will affect interest paid on variable-rate debt and
interest earned by our nuclear decommissioning trust fund. Our policy is to
manage interest rates through the use of a combination of fixed-rate and
floating-rate debt. The nuclear decommissioning fund also has risks associated
with changing market values of equity investments. Nuclear decommissioning costs
are recovered in regulated electricity prices.

     COMPETITION AND ELECTRIC INDUSTRY RESTRUCTURING

     See Note 5 of Notes to Condensed Financial Statements in Part I, Item 1 of
this report for a discussion of regulatory developments regarding the
introduction of retail electric competition in Arizona and related matters.

     PALO VERDE NUCLEAR GENERATING STATION

     In February 2002, the U. S. Secretary of Energy recommended to President
Bush that the Yucca Mountain, Nevada site be developed as a permanent repository
for spent nuclear fuel. The President transmitted this recommendation to
Congress and the State of Nevada vetoed the President's recommendation. See
"Palo Verde Nuclear Generating Station" in Part II, Item 5 of the March 10-Q.
Congress recently approved the Yucca Mountain site, overriding the Nevada veto.
It is now expected that the U.S. Department of Energy will submit a license
application to the NRC late in 2004.

     NATURAL GAS SUPPLY

     In a pending FERC proceeding, EL Paso Natural Gas Company has proposed
allocating its gas pipeline capacity in such a way that our (and other companies
with the same contract type) gas transportation rights could be significantly
impacted, and various parties, including us and Pinnacle West Energy, have
challenged this allocation. See "Generating Fuel and Purchased Power - Natural
Gas Supply" in Part I, Item 1 of the 2001 10-K. The FERC conducted a public
conference in April 2002 to discuss an appropriate mechanism for allocating
capacity on the El Paso Natural Gas Company pipeline. On May 31, 2002 the FERC
issued an order requiring the conversion of all firm, Full Requirements
contracts to Contract Demand contracts by November 1, 2002. In addition, the
FERC order set forth procedures to encourage parties to resolve the details of
such conversions through the settlement process. We and other Full Requirement
contract holders have sought rehearing of the FERC order and have requested a
stay of the November 1, 2002 implementation date. We cannot currently predict
the outcome of this matter.

     COAL SUPPLY

     Because covenants under the Four Corners lease and related federal
rights-of-way and grants expired in July 2001, the Navajo Nation assessed taxes
on the coal supplier and the plant. See "Generating Fuel and Purchased Power -
Coal Supply - Four Corners" in Part I, Item 1 of the 2001 10-K. In July 2002, we
negotiated a settlement agreement with the Navajo Nation relating to the plant
pursuant to which we will make settlement payments to the Navajo Nation. That
settlement agreement is expected to be executed in August 2002. Pursuant to the
terms of the settlement agreement, we do not expect the payments to have a
material adverse impact on our financial position, results of operations or
liquidity.
