                        PINNACLE WEST CAPITAL CORPORATION
              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. The Condensed Consolidated Financial Statements include the accounts of the
Company and its subsidiaries: APS, Pinnacle West Energy, APS Energy Services,
SunCor, and El Dorado. All significant intercompany accounts and transactions
have been eliminated. We have reclassified certain prior year amounts to conform
to the current year presentation.

2. Our unaudited Condensed Consolidated 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 Consolidated Financial Statements and Notes to
Condensed Consolidated Financial Statements be read along with the Consolidated
Financial Statements and Notes to Consolidated Financial Statements included in
our 2000 10-K.

3. Weather conditions and trading and wholesale power marketing activities can
have significant impacts on our results for interim periods. Results for interim
periods do not necessarily represent results to be expected for the year.

4. See "Liquidity and Capital Resources" in Part I, Item 2 of this report for
changes in capitalization for the nine months ended September 30, 2001.

5. Regulatory Accounting

     APS is regulated by the ACC and FERC. The accompanying financial statements
reflect the ratemaking policies of these commissions. For regulated operations,
we prepare our financial statements in accordance with SFAS No. 71, "Accounting
for the Effects of Certain Types of Regulation." SFAS No. 71 requires a
cost-based, rate-regulated enterprise to reflect the impact of regulatory
decisions in its financial statements.

     During 1997, the EITF of the FASB issued EITF 97-4. EITF 97-4 requires that
SFAS No. 71 be discontinued no later than when legislation is passed or a rate
order is issued that contains sufficient detail to determine its effect on the
portion of the business being deregulated, which could result in write-downs or
write-offs of physical and/or regulatory assets. Additionally, the EITF
determined that regulatory assets should not be written off if they are to be
recovered from a portion of the entity which continues to apply SFAS No. 71.

     The 1999 Settlement Agreement was approved by the ACC in September 1999
(see Note 6 for a discussion of the agreement). Consequently, we have
discontinued the application of SFAS No. 71 for our generation operations. As a
result, we tested the generation assets for impairment and determined that the
generation assets were not impaired. Pursuant to the 1999 Settlement Agreement,
a regulatory disallowance removed $234 million pretax ($183 million net present
value) from ongoing regulatory cash flows and was recorded as a net reduction of
regulatory assets. This reduction ($140 million after income taxes, or $1.65 per
basic or diluted share) was reported as an extraordinary charge on the income
statement during the third quarter of 1999. Prior to the 1999 Settlement

                                       -9-

Agreement, under the 1996 regulatory agreement (see Note 6), the ACC accelerated
the amortization of substantially all of our regulatory assets to an eight-year
period that would have ended June 30, 2004.

     The regulatory assets to be recovered under the 1999 Settlement Agreement
are now being amortized through June 30, 2004 as follows (dollars in millions):

                                                     1/1 - 6/30
     1999      2000      2001      2002      2003       2004       Total
     ----      ----      ----      ----      ----       ----       -----
     $164      $158      $145      $115       $86        $18        $686

     The majority of our remaining regulatory assets relate to deferred income
taxes and rate synchronization cost deferrals.

     The consolidated balance sheets include the amounts listed below for
generation assets not subject to SFAS No. 71 (for additional generation
information see Note 8):

6. Regulatory Matters

ELECTRIC INDUSTRY RESTRUCTURING

STATE

     1999 SETTLEMENT AGREEMENT. On May 14, 1999, APS entered into a
comprehensive Settlement Agreement with various parties, including
representatives of major consumer groups, related to the implementation of
retail electric competition. On September 23, 1999, the ACC voted to approve the
1999 Settlement Agreement, with some modifications. On December 13, 1999, two
parties filed lawsuits challenging the ACC's approval of the 1999 Settlement
Agreement. Each party bringing the lawsuits appealed the ACC's order approving
the 1999 Settlement Agreement directly to the Arizona Court of Appeals, as
provided by Arizona law. In one of the appeals, on December 26, 2000, the
Arizona Court of Appeals affirmed the ACC's approval of the 1999 Settlement
Agreement. This decision was not appealed and has become final. In the other
appeal, on April 5, 2001, the Arizona Court of Appeals again affirmed the ACC's
approval of the 1999 Settlement Agreement. The Arizona Consumers Council, which
filed that appeal, petitioned the Arizona Supreme Court for review of the Court
of Appeals' decision. On October 5, 2001, the Arizona Supreme Court agreed to
hear the appeal on the singular issue of whether the ACC could itself become a
party to the Settlement Agreement by virtue of its

                                      -10-

approval of the Settlement Agreement. The Supreme Court has not yet set a date
for oral argument on this matter.

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

*    APS has 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 the July 1, 1999 retail price
     decrease of approximately $11 million ($7 million after income taxes)
     related to the 1996 regulatory agreement. See "1996 Regulatory Agreement"
     below. 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, and
     approximately $27 million ($16 million after taxes), or 1.5%, effective
     July 1, 2001. For customers having loads three MW or greater, standard
     offer rates will be reduced in varying annual increments that total 5% in
     the years 1999 through 2002.

*    Unbundled rates being charged by APS 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 APS 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, or material changes in APS' cost of service
     for ACC-regulated services resulting from federal, tribal, state or local
     laws, regulatory requirements, judicial decisions, actions or orders.

*    APS will be permitted to defer for later recovery prudent and reasonable
     costs of complying with the ACC electric competition 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.

*    APS' 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 electric competition rules (see
     "Retail Electric Competition Rules" below), including an additional 140 MW
     being made available to eligible non-residential customers. APS opened its
     distribution system to retail access for all customers on January 1, 2001.

                                      -11-

*    Prior to the 1999 Settlement Agreement, APS was recovering substantially
     all of its regulatory assets through July 1, 2004, pursuant to the 1996
     regulatory agreement. In addition, the 1999 Settlement Agreement states
     that APS has demonstrated that its allowable stranded costs, after
     mitigation and exclusive of regulatory assets, are at least $533 million
     net present value. APS will not be allowed to recover $183 million net
     present value of the above amounts. The 1999 Settlement Agreement provides
     that APS 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.

*    APS will form, or cause to be formed, a separate corporate affiliate or
     affiliates and transfer to such affiliate(s) its generating assets and
     competitive services at book value as of the date of transfer, and will
     complete the transfer no later than December 31, 2002. Accordingly, APS
     plans to complete the move of such assets and services from APS to the
     parent company or to Pinnacle West Energy by the end of 2002, as required.
     APS will be allowed to defer and later collect, beginning July 1, 2004,
     sixty-seven percent of its costs to accomplish the required transfer of
     generation assets to an affiliate.

*    When the 1999 Settlement Agreement approved by the ACC is no longer subject
     to judicial review, APS will move to dismiss all of its litigation pending
     against the ACC as of the date APS entered into the 1999 Settlement
     Agreement. To protect its rights, APS has several lawsuits pending on ACC
     orders relating to stranded cost recovery and the adoption and amendment of
     the ACC's electric competition rules, which would be voluntarily dismissed
     at the appropriate time under this provision.

     As discussed in Note 5 above, we have discontinued the application of SFAS
No. 71 for our generation operations.

     PROPOSED RULE VARIANCE AND PURCHASE POWER AGREEMENT. As authorized by the
1999 Settlement Agreement, APS intends to move substantially all of its
generation assets to Pinnacle West Energy no later than December 31, 2002.
Commencing upon 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 the Company's power marketing division, which, in
turn, is expected to sell power to APS and to non-affiliated power purchasers.
In a filing with the ACC on October 18, 2001, APS requested the ACC to (a) grant
APS a partial variance from an ACC rule that would obligate APS to acquire all
of its customers' standard offer generation requirements from the competitive
market (with at least 50% of that coming from a "competitive bidding" process)
starting in 2003 and (b) approve as just and reasonable a long-term purchase
power agreement (PPA) between APS and the Company. APS has requested these ACC
actions to ensure continued reliable service to APS standard offer customers in
a volatile generation market and to recognize Pinnacle West Energy's significant
investment to serve APS load. The following are the major provisions of the PPA:

                                      -12-

*    The PPA would run through 2015, with three optional five-year renewal
     terms, which renewals would occur automatically unless notice is given by
     either APS or the Company.

*    The PPA would provide for all of APS' anticipated standard offer generation
     needs, including any necessary reserves, except for (a) those provided by
     APS itself through renewable resources or other generation assets retained
     by APS; (b) amounts that APS is obligated by law to purchase from
     "qualified facilities" and other forms of distributed generation; and (c)
     any purchased power agreements that APS cannot transfer to Pinnacle West
     Energy.

*    The Company would assume contractual responsibility for reliability and
     would supplement any potential shortfall even after full utilization of
     Pinnacle West Energy's dedicated generating resources.

*    The Company would supply APS standard offer requirements through a
     combination of (a) APS generation assets transferred to Pinnacle West
     Energy; (b) certain of Pinnacle West Energy's new Arizona generation
     projects to be constructed during the 2001-2004 period to reliably serve
     APS load requirements; (c) power procured by the Company under certain
     "dedicated contracts"; and (d) power procured on the open market, including
     a competitively-bid component described below.

*    Beginning in 2003, the Company would acquire 270 MW of APS standard offer
     requirements on the open market through a competitive bidding process. This
     competitive bid obligation would be increased by an additional 270 MW each
     year through 2008 (representing approximately 23% of estimated 2008 peak
     load).

*    The Company would charge APS based on (a) a combination of fixed and
     variable price components for the Pinnacle West Energy assets, subject to
     periodic adjustment, and (b) a pass-through of the Company's costs to
     procure power from the remaining sources.

*    The PPA would take effect on the latest of the following events: (a)
     transfer of non-nuclear generating assets from APS to Pinnacle West Energy;
     (b) ACC approval of the rule variance and the PPA; and (c) FERC acceptance
     of the PPA and the companion agreement between the Company and Pinnacle
     West Energy.

     PROVIDER OF LAST RESORT OBLIGATION. Although the Rules allow retail
customers to have access to competitive providers of energy and energy services
(see "Retail Electric Competition Rules" below), APS is the "provider of last
resort" for standard offer customers under rates that have been approved by the
ACC. Energy prices in the western wholesale market vary and, during the course
of the last year, have been volatile. At various times, prices in the spot
wholesale market have significantly exceeded the amount included in APS' current
retail rates. APS expects that the market may continue to be volatile. We
believe that through a combination of hedging and our current generation
portfolio, we will be able to adequately manage our exposure to the volatility
of the power market. However, in the event of shortfalls due to unforeseen
increases in load demand or generation outages, APS may need to purchase
additional supplemental power in the wholesale spot

                                      -13-

market. Unless APS is able to obtain an adjustment of its rates under the
emergency provisions of the 1999 Settlement Agreement, there can be no assurance
that APS would be able to fully recover the costs of this power.

     RETAIL ELECTRIC COMPETITION RULES. On September 21, 1999, the ACC voted to
approve rules that provide a framework for the introduction of retail electric
competition in Arizona. 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, APS 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 December 8,
1999, APS filed a lawsuit to protect its legal rights regarding the Rules. This
lawsuit is pending, along with several other lawsuits on ACC orders relating to
stranded cost recovery (including those described above involving APS), the
adoption or amendment of the Rules, and the certification of competitive
electric service providers.

     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,
including APS Energy Services, 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 APS' 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 case has been appealed to the Arizona Supreme Court, where a decision is
pending.

     The Rules approved by the ACC include the following major provisions:

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

*    Effective January 1, 2001, retail access became available to all APS 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.

                                      -14-

*    Affected utilities must file ACC tariffs that unbundle rates for
     non-competitive 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
     generation assets and services either to an unaffiliated party or to a
     separate corporate affiliate. Under the 1999 Settlement Agreement, APS
     received a waiver to allow transfer of its generation and other competitive
     assets and services to affiliates no later than December 31, 2002. APS
     plans to complete the move of such assets by the end of 2002, as required.

     1996 REGULATORY AGREEMENT. In April 1996, the ACC approved a regulatory
agreement between the ACC Staff and APS. Based on the price reduction formula
authorized in the agreement, the ACC approved retail price decreases
(approximate) as follows (dollars in millions):

      Annual Electric                Percentage
     Revenue Decrease                 Decrease           Effective Date
     ----------------                 --------           --------------
           $49                          3.4%             July 1, 1996
           $18                          1.2%             July 1, 1997
           $17                          1.1%             July 1, 1998
           $11                          0.7%             July 1, 1999 (a)

----------
(a)  Included in the first rate reduction under the 1999 Settlement Agreement
     (see above).

     The regulatory agreement also required that we infuse $200 million of
common equity into APS in annual payments of $50 million from 1996 through 1999.
All of these equity infusions were made by December 31, 1999.

     LEGISLATION. In May 1998, a law was enacted to facilitate implementation of
retail electric competition in Arizona. The law includes the following major
provisions:

     *    Arizona's largest government-operated electric utility (Salt River
          Project) and, at their option, smaller municipal electric systems must
          (i) make at least 20% of their 1995 retail peak demand available to
          electric service providers by December 31, 1998 and for all retail
          customers by December 31, 2000; (ii) decrease rates by at least 10%
          over a ten-year period beginning as early as January 1, 1991; (iii)
          implement procedures and public processes comparable to those already
          applicable to public service corporations for establishing the terms,
          conditions, and pricing of electric services as well as certain other
          decisions affecting retail electric competition;

     *    describes the factors which form the basis of consideration by Salt
          River Project in determining stranded costs; and

                                      -15-

     *    metering and meter reading services must be provided on a competitive
          basis during the first two years of competition only for customers
          having demands in excess of one MW (and that are eligible for
          competitive generation services), and thereafter for all customers
          receiving competitive electric generation.

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.

FEDERAL

     The 1992 Energy Act and recent rulemakings by FERC have promoted increased
competition in the wholesale energy markets. We do not expect these rules to
have a material impact on our financial statements.

     In June 2001, 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 remains in effect until September 30, 2002. The Company
cannot accurately predict the overall financial impact of the plan on the
various aspects of its business, including its wholesale and purchased power
activities.

7. Nuclear Insurance

     The Palo Verde participants have insurance for public liability payments
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, APS
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 APS'
29.1% interest in the three Palo Verde units, APS' maximum potential assessment
per incident 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 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. APS has 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.

                                      -16-

8. Business Segments

     We have two principal business segments (determined by products, services
and regulatory environment),which consist of activities related to the
transmission and distribution of electricity (delivery business segment) and the
generation of electricity and wholesale and power trading (generation business
segment).

     These reportable segments reflect a change in the reporting of our
functional activities. Before January 1, 2001, our reported segment information
combined transmission and distribution activities with wholesale and power
trading activities. Our current operational activities are more closely based on
the strong integration of our wholesale and power trading activities with our
generation of electricity, and have been combined for segment reporting
purposes. The corresponding information for earlier periods has been restated.

     Beginning in 2001, we changed our method of allocating revenues between the
delivery business segment and the generation business segment to reflect the
seasonal impact of market prices. This change had the impact of decreasing
delivery segment income and increasing generation segment income in all the
periods presented when compared to the prior comparable periods. The after-tax
change is $45 million in the three-month period and $2 million in the nine- and
twelve-month periods.

     The other amounts include activity relating to the parent company and other
subsidiaries, including APS Energy Services, SunCor and El Dorado. Eliminations
primarily relate to intersegment sales of electricity. Segment information for
the three, nine and twelve months ended September 30, 2001 and 2000 is as
follows (dollars in millions):

9. Accounting Matters

     In July 2001, the FASB issued 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 are currently evaluating the impacts of the new standard
and do not expect it to have a material impact on our financial statements. We
have no goodwill. This standard is effective for the year beginning January 1,
2002.

     In August 2001, the FASB issued SFAS No. 143, "Accounting for Asset
Retirement Obligations." The standard requires the estimated present value of
the cost of decommissioning and certain other removal costs to be recorded as a
liability, along with an offsetting plant asset when a decommissioning or other
removal obligation is incurred. We are currently evaluating the impacts of the
new standard, which is effective for the year beginning January 1, 2003.

     In October 2001, the FASB issued 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. SFAS No. 144 is effective for the year
beginning January 1, 2002. We are currently evaluating the impacts of the new
standard and do not expect it to have a material impact on our financial
statements.

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/credits. The changes in market value of such contracts have a high
correlation to price changes in the hedged commodity. In addition, subject to
specified risk parameters established by the Board of Directors and monitored by
the ERMC, we engage in trading activities intended to profit from market price
movements.

     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 sheet and measure those instruments at fair value. Changes in the fair
value of derivative financial instruments are

                                      -18-

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. Hedge effectiveness is measured based on the
relative changes in fair value between the derivative contract and the hedged
item over time. Any change in the fair value resulting from ineffectiveness is
recognized immediately in net income. This new standard may result in additional
volatility in our net income and comprehensive income.

     In June 2001, the FASB determined that certain electricity contracts,
including those with option characteristics and those subject to "bookout,"
would qualify for the normal purchases and sales exception if certain criteria
were met. Prior to the issuance of the guidance, we accounted for electricity
contracts with characteristics of options and those subject to "bookout" as
normal purchases and sales. As a result, we did not previously mark these
contracts to their fair market values each reporting period. The effective date
of this new guidance was July 1, 2001.

     As a result of adopting SFAS No. 133, we recognized $118 million of
derivative assets and $16 million of derivative liabilities in our balance sheet
as of January 1, 2001. Also as of January 1, 2001, we recorded a $3 million
after-tax loss, or $0.03 per basic or diluted share, in net income as a
cumulative effect of a change in accounting principle and a $65 million
after-tax gain in equity (as a component of other comprehensive income). The
gain resulted from unrealized gains on cash flow hedges.

     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. These adjustments resulted primarily from contracts
with characteristics of options that did not meet the new criteria for the
normal purchases and sales exception. The impact of the new guidance is
reflected as a cumulative effect of a change in accounting principle. In October
2001, FASB again revised its guidance for option-like contracts. We are
currently in the process of evaluating the effect, if any, of this revised
guidance.

     The change in derivative fair value in the consolidated statements of
income for the three, nine and twelve months ending September 30, 2001 and 2000
is comprised of the following (dollars in thousands):

(a)  Time value component of options excluded from assessment of hedge
     effectiveness.

     As of September 30, 2001, the maximum length of time over which we are
hedging our exposure to the variability in future cash flows for forecasted
transactions is thirty-nine months. During the twelve months ending September
30, 2002, we estimate that a net loss of $23 million before income taxes will be
reclassified from accumulated other comprehensive income as an offset to the
effect on earnings of market price changes for the related hedged transaction.

     Net gains and losses on derivatives utilized for trading activities are
recognized in power marketing revenues on a current basis (the mark-to-market
method). Trading positions are measured at fair value as of the balance sheet
date. The mark-to-market gains recognized in power marketing revenues were the
following for the three, nine and twelve months ended September 30, 2001 and
2000 (dollars in millions):

12. Generation Expansion

          PINNACLE WEST ENERGY

     Pinnacle West Energy has announced plans to build about 3,277 MW of natural
gas-fired generating capacity from 2001-2006 at an estimated cost of about $1.7
billion.

----------
* 75% Pinnacle West Energy Share of 570 MW Unit

     Pinnacle West Energy is currently funding its capital requirements through
capital infusions from the parent company, which finances those infusions
through debt financings and internally generated cash. As Pinnacle West Energy
develops and obtains additional generation assets, Pinnacle West Energy expects
to fund its capital requirements through internally generated cash and its own
debt issuances.

     Pinnacle West Energy has completed or is currently planning the following
projects:

     *    A 650 MW expansion of the West Phoenix Power Plant in Phoenix. The 120
          MW West Phoenix Unit 4 began commercial operation on June 1, 2001.
          Construction has begun on the 530 MW West Phoenix Unit 5, with
          commercial operation expected to begin in mid-2003.

     *    The construction of a four-unit generating station near Palo Verde,
          called Redhawk. Redhawk Units 1 and 2 will be combined-cycle units.
          Construction began in December 2000, and commercial operation is
          currently scheduled for the Summer of 2002. Pinnacle West Energy is
          evaluating initially constructing Redhawk Units 3 and 4 as
          simple-cycle units, to be converted to combined-cycle units at a later
          date.

     *    Pinnacle West Energy is also constructing an 80 MW simple-cycle power
          plant at Saguaro in Southern Arizona. Commercial operation is
          currently scheduled for the Summer of 2002.

     *    Pinnacle West Energy plans to develop an electric generating station
          20 miles north of Las Vegas, Nevada. Construction of the 570 MW
          Silverhawk combined-cycle plant is expected to begin in the Spring of
          2002 with an expected commercial operation date of mid-2004. The
          Company has signed a memorandum of understanding with Las Vegas-based
          Southern Nevada Water Authority for them to be a 25-percent owner of
          the plant.

     A Pinnacle West Energy affiliate is exploring the possibility of creating
an underground natural gas storage facility on company-owned land west of
Phoenix. A

                                      -22-

feasibility study is in progress to determine if the proposed acreage can
support a natural gas storage cavern. Results are expected by the end of 2001.

13. El Dorado Partnership Investment Income

     Net other income has consisted primarily of El Dorado's share in the
earnings of a venture capital partnership. We record our share of the earnings
from the partnership as the partnership adjusts the value of its investment. In
2001, El Dorado received a distribution of securities representing substantially
all of El Dorado's investment in the partnership. The securities were sold in
the first quarter of 2001 and a gain was recognized in other income.

14. California Energy Market Issues and Refunds in the Pacific Northwest

     We are closely monitoring developments in the California energy market and
the potential impact of those developments on us and our subsidiaries. We have
evaluated, among other things, SCE's role as a Palo Verde and Four Corners
participant; APS' transactions with the PX and the ISO; contractual
relationships with SCE and PG&E; APS Energy Services' retail transactions
involving SCE and PG&E; and power marketing exposures. Based on our current
evaluations, we have reserved $10 million before income taxes for our credit
exposure related to the California energy situation. 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 our
subsidiaries or the regional energy market in general.

     In July 2001, 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 FERC after
the California ISO provides necessary historical data. FERC also ordered an
evidentiary proceeding to discuss and evaluate possible refunds for the Pacific
Northwest. The Administrative Law Judge at 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 FERC Commissioners. Although 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 will have a material adverse impact on our financial position,
results of operations or liquidity.

15. Legal Proceedings

     SunCor is a party to a lawsuit pending in Maricopa County, Arizona,
Superior Court entitled SUNCOR DEVELOPMENT COMPANY V. BERGSTROM CORPORATION, CV
98-11472. On March 15, 2001, a jury returned a verdict against SunCor in the
amount of $28.6 million, $25.7 million of which represents a punitive damage
award. The verdict was based on the Bergstrom Corporation's claims that it was
defrauded in connection with the acquisition of approximately ten acres of land
in a SunCor commercial development and a subsequent settlement agreement
relating to those claims. SunCor believes that the verdict is neither supported
by the evidence or the law and has filed post-trial motions to that effect and,
if necessary, will appeal. On September 27, 2001, the Court denied SunCor's
motions for a new trial and for a reduction of the compensatory damage award,
but ruled that it was not

                                      -23-

yet in a position to rule on the amount of the punitive damages award and
requested additional information from the parties on this issue. We do not
expect this litigation to have a material adverse impact on our financial
position, results of operations or liquidity.

16. Power Service Agreement

     By letter dated March 7, 2001, Citizens advised APS that it believes APS
has overcharged Citizens by over $50 million under a power service agreement.
APS believes that its charges under the agreement were fully in accordance with
the terms of the agreement. APS and Citizens terminated the power service
agreement effective July 15, 2001. In replacement of the power service
agreement, the Company and Citizens entered into a power sale agreement under
which the Company 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.

17. 2001 Generation Summer Reliability Program

     We recently added over 500 MW of generating capability to enhance
reliability for the summer of 2001 in light of market conditions in the western
United States. The additional capacity included the 120 MW West Phoenix Unit 4
(see Note 12) and approximately 200 MW of gas-fired portable generators leased
for the summer of 2001 by Pinnacle West Energy. Additionally, APS restored
approximately 100 MW of previously mothballed gas-fired steam units at the West
Phoenix Power Plant and refurbished the entire fossil plant fleet during the
spring of 2001 (which resulted in additional capability of approximately 110
MW).

OVERVIEW OF OUR BUSINESS

     Pinnacle West owns all of the outstanding common stock of APS. APS is

     OPERATING RESULTS - THREE-MONTH PERIOD ENDED SEPTEMBER 30, 2001 COMPARED
     WITH THREE-MONTH PERIOD ENDED SEPTEMBER 30, 2000

     Our consolidated net income for the three months ended September 30, 2001
was $150 million compared with $116 million for the same period in the prior
year. In July 2001, we recognized a $12 million after-tax loss in net income as
a cumulative effect of a change in accounting for derivatives as required by
SFAS No. 133. See Note 10 for further discussion.

     Income before accounting change for the three months ended September 30,
2001 was $162 million compared with $116 million for the same period in the
prior year. The major factors that increased (decreased) income before
accounting change were as follows (dollars in millions):

     Electric operating revenues decreased approximately $37 million primarily
because of:

*    change in power marketing, trading and wholesale revenues ($42 million, net
     decrease):
     *    increased trading revenues related to structured power trading
          activities ($128 million);
     *    decreased wholesale revenues primarily related to generation sales
          other than for Native Load ($2 million);
     *    decreased power marketing revenues related to other trading and other
          wholesale activities ($168 million);
*    increased retail revenues primarily related to higher sales volumes due to
     weather impacts and customer growth, partially offset by lower average
     usage per customer ($14 million); and
*    decreased retail revenues related to the reduction in retail electricity
     prices ($9 million). See Note 6 for information on the price reductions.

     Purchased power and fuel expenses decreased approximately $129 million
primarily because of:

*    changes related to power marketing, trading and wholesale sales ($127
     million, net decrease):
     *    increased trading costs related to structured power trading activities
          ($76 million);
     *    decreased costs related to generation other than Native Load ($5
          million);
     *    decreased power marketing costs related to other trading and other
          wholesale activities ($198 million);
*    decreased costs for a SFAS No. 133 adjustment related to changes in
     electricity and gas market prices ($17 million). See Note 10 for additional
     information on SFAS No. 133;
*    increased costs related to higher retail sales volumes and associated
     higher purchased power and fuel prices ($9 million); and
*    higher replacement power costs primarily for increased plant outages ($6
     million).

                                      -28-

     The increase in operations and maintenance expenses of $37 million
primarily related to the generation summer reliability program (the addition of
approximately 500 MW of generating capability to enhance reliability for the
summer of 2001, particularly the leasing of gas-fired portable generators) ($29
million) and other costs ($8 million). See Note 17 for additional information on
the generation summer reliability program.

     Depreciation and amortization decreased $6 million primarily because of
lower regulatory asset amortization.

     Net other income increased $13 million primarily because of a change in the
market value of El Dorado's investment in a technology-related venture capital
partnership in the prior-year period (see Note 13).

     Interest expense decreased by $6 million primarily because of increased
capitalized interest resulting from our generation expansion plan. See Note 12
for additional information on the generation expansion plan.

     OPERATING RESULTS - NINE-MONTH PERIOD ENDED SEPTEMBER 30, 2001 COMPARED
     WITH NINE-MONTH PERIOD ENDED SEPTEMBER 30, 2000

     Our consolidated net income for the nine months ended September 30, 2001
was $276 million compared with $260 million for the same period in the prior
year. In 2001, we recognized a $15 million after-tax loss in net income as a
cumulative effect of a change in accounting for derivatives, as required by SFAS
No. 133. See Note 10 for further discussion.

     Income before accounting change for the nine months ended September 30,
2001 was $291 million compared with $260 million for the same period in the
prior year. The major factors that increased (decreased) income before
accounting change were as follows (dollars in millions):

                                      -29-

     Electric operating revenues increased approximately $964 million primarily
because of:

*    change in power marketing, trading and wholesale revenues ($928 million,
     net increase):
     *    increased trading revenues related to structured power trading
          activities ($128 million);
     *    increased wholesale revenues primarily related to generation sales
          other than for Native Load ($182 million);
     *    increased power marketing revenues related to other trading and other
          wholesale activities ($618 million);
*    increased retail revenues primarily related to higher sales volumes due to
     weather impacts and customer growth, partially offset by lower average
     usage per customer ($58 million); and
*    decreased retail revenues related to reductions in retail electricity
     prices ($22 million). See Note 6 for information on the price reductions.

     Purchased power and fuel expenses increased approximately $831 million
primarily because of:

*    changes related to power marketing, trading and wholesale sales ($678
     million, net increase):
     *    increased trading costs related to structured power trading activities
          ($76 million);
     *    increased costs related to generation other than Native Load ($64
          million);
     *    increased power marketing costs related to other trading and other
          wholesale activities ($538 million);
*    higher replacement power costs primarily for increased plant outages ($94
     million), including costs of $12 million related to the Palo Verde outage
     extension to replace fuel control element assemblies;
*    increased costs related to higher retail sales volumes and associated
     higher purchased power and fuel prices ($68 million); and
*    decreased costs related to SFAS No. 133 adjustments related to changes in
     electricity and gas market prices ($9 million). See Note 10 for additional
     information on SFAS No. 133.

     The increase in operations and maintenance expenses of $77 million
primarily related to the generation summer reliability program (the addition of
approximately 500 MW of generating capability to enhance reliability for the
summer of 2001) and increased power plant maintenance ($56 million), increased
pension and other costs ($16 million) and a provision for credit exposure
related to the California energy situation ($5 million). See Note 17 for
additional information on the generation summer reliability program. See Note 14
for additional information related to the California energy situation.

     Depreciation and amortization decreased $7 million primarily because of
lower regulatory asset amortization.

     Net other income decreased by $13 million primarily because of a change in
the market value of El Dorado's investment in a technology-related venture
capital partnership

                                      -30-

in the prior year period (see Note 13) and other non-operating costs, partially
offset by an insurance recovery of environmental remediation costs.

     Interest expense decreased by $16 million primarily because of increased
capitalized interest resulting from our generation expansion plan. See Note 12
for additional information on the generation expansion plan.

*    decreased retail revenues related to the reduction in retail electricity
     prices ($27 million). See Note 6 for information on the price reductions.

     Purchased power and fuel expenses increased approximately $1.11 billion
primarily because of:

*    changes related to power marketing, trading and wholesale sales ($924

     *    increased power marketing costs related to other trading and other
          wholesale activities ($742 million);
*    higher replacement power costs primarily for increased plant outages ($116
     million), including costs of $12 million related to the Palo Verde outage
     extension to replace fuel control element assemblies;
*    higher costs related to retail sales volumes and associated purchased power
     and fuel prices ($80 million); and
*    decreased costs for SFAS No. 133 adjustments related to changes in
     electricity and gas market prices ($9 million). See Note 10 for additional
     information on SFAS No. 133.

     The increase in operations and maintenance expenses of $68 million
primarily related to generation summer reliability programs (the addition of
approximately 500 MW of generating capability to enhance reliability for the
summer of 2001) and increased power plant maintenance ($61 million), increased
pension and other costs ($10 million), and provisions for credit exposure
related to the California energy situation ($10 million), partially offset by
approximately $13 million of non-recurring items recorded in the fourth quarter
of 1999. See Note 17 for information on the generation summer reliability
program. See Note 14 for additional information related to the California energy
situation.

     Net other income decreased $39 million primarily because of a change in the
market value of El Dorado's investment in a technology-related venture capital
partnership in the prior year period (see Note 13) and other non-operating costs
offset by an insurance recovery of environmental remediation costs.

     Interest expense decreased by $19 million primarily because of increased
capitalized interest resulting from our generation expansion plan. See Note 12
for additional information on the generation expansion plan.

     CAPITAL RESOURCES AND DEBT FINANCING

          PINNACLE WEST

     The parent company's cash requirements and its 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 2000 10-K.

     During the nine-months ended September 30, 2001, the parent company
increased its outstanding indebtedness by about $400 million. During the
nine-month period ended September 30, 2001, the parent company issued $550
million in long-term debt and $122 million in short-term borrowings and repaid
$275 million of long- and short-term debt. The majority of these borrowings were
used to fund Pinnacle West Energy capital expenditures.

          APS

     APS' long-term debt redemption requirements, including optional repayments
on long-term debt are: $384 million in 2001; $125 million in 2002; and zero in
2003. During 2001, APS expects to satisfy its long-term debt redemption
requirements with cash from operations and long and short-term borrowings.
Through September 2001, APS redeemed

                                      -33-

$62 million of its long-term debt. APS has also deposited $72 million, plus
interest, with the trustee for redemption in December 2001 of its First Mortgage
Bonds, 9% Series due 2021. On October 5, 2001, APS issued $400 million of 6.375%
Notes due 2011. Based on market conditions and optional call provisions, APS may
make optional redemptions of long-term debt from time to time.

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

          PINNACLE WEST ENERGY

     See Note 12 of Notes to Condensed Consolidated Financial Statements for a
discussion of construction and financing programs relating to Pinnacle West
Energy.

          OTHER SUBSIDIARIES

     SunCor and El Dorado each fund all of their cash requirements with cash
from operations and, in the case of SunCor, its own external financings. APS
Energy Services funds its cash requirements with cash infusions from the parent
company.

     SunCor's capital needs consist primarily of capital expenditures for land
development and retail and office building construction. See the Capital
Expenditures table above for actual capital expenditures for the nine months
ended September 30, 2001 and projected capital expenditures through 2003. SunCor
expects to fund its capital requirements from internally generated cash and its
own external financings.

     El Dorado intends to focus on the realization of the value of its existing
investments and does not have any capital requirements over the next three
years. El Dorado's future investments are expected to be limited to
opportunities related to the energy sector.

BUSINESS OUTLOOK

     This section describes several major factors affecting our financial
outlook.

     COMPETITION AND ELECTRIC INDUSTRY RESTRUCTURING

     See "Business Outlook - Competition and Industry Restructuring" in Item 7
of the 2000 10-K and Note 6 above for a discussion of developments affecting
retail and wholesale electric competition. See Note 5 for a discussion of
regulatory accounting.

     GENERATION EXPANSION

     See Note 12 for information regarding our generation expansion plans. The
planned additional generation is expected to increase revenues, fuel expenses,
operating expenses, and financing costs.

                                      -34-

     CALIFORNIA ENERGY MARKET ISSUES AND REFUNDS IN THE PACIFIC NORTHWEST

     See Note 14 for information regarding California energy market issues and
possible Pacific Northwest refunds.

     FACTORS AFFECTING OPERATING REVENUES

     Electric operating revenues are derived from sales of electricity in
regulated retail markets in Arizona and in 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 APS' regulated retail market area, APS 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 APS' service territory averaged 4.1% a year for
the three years 1998 through 2000; we currently expect customer growth to
average 3% to 4% a year for 2001 through 2003. We currently estimate that retail
electricity sales in kilowatt-hours will grow 3% to 4.5% a year in 2001 through
2003, 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 APS' standard offer customers that will switch to
unbundled service.

     Wholesale activities will be affected by electricity prices and costs of
available fuel and purchased power in the western United States, as well as
competitive market conditions and regulatory and legislative changes in various
state and federal jurisdictions, including the price mitigation plan adopted by
FERC in June 2001 (see Note 6). These factors have significantly affected our
trading and wholesale power activities and their resultant earnings
contributions over the last several years. We cannot predict future
contributions from trading and wholesale activities. See Note 10 and Item 3
below for additional information.

     Competitive sales of energy and energy-related products and services are
made by APS Energy Services in western states that have opened to competitive
supply. Such activities are currently not material to our consolidated financial
results.

     OTHER FACTORS AFFECTING FUTURE FINANCIAL RESULTS

     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, and our hedging program for
managing such costs. See "Natural Gas Supply" in Part II for additional
information on gas transportation costs.

     Operations and maintenance expenses are expected to be affected by sales
mix and volumes, power plant operations, inflation, and other factors.

                                      -35-

     Depreciation and amortization expenses are expected to be affected by net
additions to existing utility plant and other property, changes in regulatory
asset amortization, and our generation expansion program. See Note 5 for the
regulatory asset amortization that is being recorded in 1999 through 2004
pursuant to the 1999 Settlement Agreement.

     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. We expect property taxes to increase primarily due to our
generation expansion program and our additions to existing facilities.

     Interest expense is affected by the amount of debt outstanding and the
interest rates on that debt. The primary factors affecting borrowing levels in
the next several years are expected to be our generation expansion program and
our internally generated cash flow.

     The annual earnings contribution from our real estate subsidiary, SunCor,
is expected to remain modest over the next several years.

     El Dorado's historical results are not necessarily indicative of future
performance for El Dorado. See Note 13 for additional information regarding El
Dorado. El Dorado's strategies focus on realization of the value of its existing
investments. Any future investments are expected to be related to the energy
business.

     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 6 for a discussion of a price reduction effective as of July 1,
2001, 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.

FORWARD-LOOKING STATEMENTS

     This document contains forward-looking statements based on current
expectations and we assume no obligation to update these statements. 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; the outcome of regulatory and
legislative proceedings relating to the restructuring; state and federal
regulatory and

                                      -36-

legislative decisions and actions, including the price mitigation plan adopted
by FERC in June 2001; regional economic and market conditions, including the
California energy situation, 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; the successful completion of our generation expansion
program; regulatory issues associated with generation expansion, such as
permitting and licensing; our ability to compete successfully outside
traditional regulated markets (including the wholesale market); technological
developments in the electric industry; and the real estate market in SunCor's
market areas, which include Arizona, New Mexico and Utah.

     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
commodity prices, interest rates, 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 our 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 these
derivative transactions to ensure that we have enough energy for our customers
and limit our exposure to volatile wholesale prices for power and fuel. In
addition, we engage in trading activities intended to profit from favorable
movements of market prices.

     As of September 30, 2001, a hypothetical adverse price movement of 10% in
the market price of our commodity derivative portfolio would decrease the fair
market value of these contracts by approximately $20 million. This analysis does
not include the favorable impact this same hypothetical price move would have on
the underlying physical exposures being hedged with the commodity derivative
portfolio. We plan to complete the move of our wholesale power marketing and
trading activities from APS to the parent company by the end of 2002.

     We are exposed to credit losses in the event of non-performance or
non-payment by counterparties. We use a credit management process to assess and
monitor the financial exposure of counterparties. Despite the fact that the
great majority of our 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 consolidated
earnings for a given period.

     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.

                           PART II - OTHER INFORMATION

ITEM 5. OTHER INFORMATION

     CONSTRUCTION AND FINANCING PROGRAMS

     See "Liquidity and Capital Resources" in Part I, Item 2 of this report for
a discussion of construction and financing programs of the Company and its
subsidiaries.

     COMPETITION AND ELECTRIC INDUSTRY RESTRUCTURING

     RETAIL. See Note 6 of Notes to Condensed Consolidated Financial Statements
in Part I, Item 1 of this report for a discussion of competition and the rules
regarding the introduction of retail electric competition in Arizona and a
settlement agreement with the ACC.

     WHOLESALE. On October 16, 2001, APS and other owners of electric
transmission lines in the Southwest filed with FERC a request for a declaratory
order confirming that their proposal to form WestConnect would satisfy FERC's
requirements for the formation of a regional transmission organization. APS and
the other filing parties have agreed to fund the start-up of WestConnect's
operations, which are projected to begin in 2004, subject to FERC approval.
WestConnect has been structured as a for-profit RTO and evolved from DesertSTAR,
a non-profit corporation in which APS participated, which was originally
designed to serve as an RTO for the southwestern United States.

     ENVIRONMENTAL MATTERS

     The Arizona Department of Environmental Quality issued to APS Notices of
Violation, dated September 25, 2001 and October 15, 2001 alleging, among other
things, burning of unauthorized materials and storage of hazardous waste without
a permit. Each Notice of Violation requires APS to achieve and document
compliance with specific environmental requirements. Although ADEQ may still
seek civil penalties or take other enforcement action against APS, APS does not
expect these matters to have a material adverse effect on its financial
position, results of operations, or liquidity.

     NATURAL GAS SUPPLY

     The gas supply for APS and Pinnacle West Energy gas-fired facilities
located, and to be located (see Note 12), in Pinal, Maricopa and Yuma Counties
in Arizona, is transported pursuant to a firm, Full Requirements Transportation
Service Agreement with El Paso Natural Gas Company. The transportation agreement
features a 10 year rate moratorium established in a comprehensive rate case
settlement entered into in 1996.

     In a pending FERC proceeding, El Paso has proposed allocating its gas
pipeline capacity in such a way that APS' (and other companies' with the same
contract type) gas transportation rights could be significantly impacted.
Various parties, including APS and Pinnacle West Energy, have challenged this
allocation as being inconsistent with El Paso's existing contractual obligations
and the 1996 settlement. At this time, there are ongoing discussions among FERC,
El Paso and other affected parties to resolve these issues. We cannot currently
predict the outcome of this matter.
