ITEM 5. OTHER EVENTS

ARIZONA ELECTRIC INDUSTRY RESTRUCTURING

     TRACK A ORDER

     On September 10, 2002, the Arizona Corporation Commission ("ACC") issued
its written order on "Track A" issues (the "Track A Order") related to the
generic docket established by the ACC in January 2002. The Track A Order
documents decisions made by the ACC at an open meeting on August 27, 2002, as
previously reported in the Report on Form 8-K of Pinnacle West Capital
Corporation (the "Company"), dated August 27, 2002. A copy of the Track A Order
is attached to this Report as Exhibit 99.1. Arizona Public Service Company
("APS") intends to file a motion for reconsideration of the Track A Order on or
before September 30, 2002. The major provisions of the Track A Order include,
among other things:

     Provisions related to the reversal of the generation asset transfer
requirement:

     *    The ACC reversed its decision, as reflected in the ACC's electric
          competition rules, to require APS to transfer its generation assets
          either to an unrelated third party or to a separate corporate
          affiliate (see the Track A Order, first Ordering Paragraph); and

     *    The ACC unilaterally modified the 1999 settlement agreement, which
          authorized APS' transfer of its generating assets, and directed APS to
          cancel its activities to transfer its generation assets to Pinnacle
          West Energy ("PWEC") (see the Track A Order, Conclusion of Law No. 7
          and the first Ordering Paragraph).

     Provisions related to the wholesale competitive energy procurement process
("Track B" issues):

     *    The ACC stayed indefinitely the requirement of the ACC's electric
          competition rules that APS acquire 100% of its energy needs for its
          standard offer customers from the competitive market, with at least
          50% obtained through a competitive bid process (see the Track A Order,
          second Ordering Paragraph);

     *    The ACC established a requirement that APS competitively procure, at a
          minimum, any required power that it cannot produce from its existing
          assets in accordance with the ultimate outcome of the Track B
          proceedings (see the Track A Order, fourth Ordering Paragraph);

     *    The ACC directed the parties to develop a competitive procurement
          ("bidding") process that can begin by March 1, 2003 (instead of
          January 1, 2003) (see the Track A Order, sixth Ordering Paragraph);
          and

     *    The ACC stated that "the PWEC generating assets that APS may acquire
          from PWEC shall not be counted as APS assets in determining the
          amount, timing and manner of the competitive solicitation" for Track B
          purposes, thereby bifurcating the regulatory treatment of the existing
          APS assets and the PWEC assets (see the Track A Order, sixth Ordering
          Paragraph).

     The ACC Staff is conducting workshops on the Track B issues with various
parties to determine and define the appropriate process to be used for
competitive power procurement. On September 13, 2002, the ACC Staff issued a
"proposal and request for comments" describing a process by which APS would
procure power not supplied by its own resources. Comments from parties
participating in the Track B process are due by September 18, 2002. The Company
cannot predict when the ACC Staff will issue its final report on the Track B
issues or when the ACC commissioners will make a final decision in this matter.
As described above, the ACC has directed the parties to complete the Track B
proceedings such that the competitive procurement process can begin by March 1,
2003.

     FINANCING APPLICATION

     The Track A Order stated that if APS wished to acquire PWEC's generating
assets, as suggested in a letter APS filed with the ACC on July 11, 2002, APS
must file an appropriate application with the ACC. On September 16, 2002, APS
filed an application with the ACC (the "Financing Application") requesting the
ACC to allow APS to borrow up to $500 million and to lend the proceeds to PWEC;
to guarantee up to $500 million of PWEC's debt; or a combination of both, not to
exceed $500 million in the aggregate. The loan and/or the guarantee would be
used to refinance debt incurred to fund the construction of PWEC generation
assets. A copy of the Financing Application is attached to this Report as
Exhibit 99.2.

     The Financing Application addresses, among other things, the following
matters:

     *    APS noted that its April 19, 2002 filing with the ACC had sought
          unification of "PWEC Assets" (West Phoenix Combined Cycle Units 4 and
          5, Redhawk Units 1 and 2, and Saguaro Combustion Turbine Unit 3) and
          APS generation assets under a common financial and regulatory regime.
          APS further noted that the Track A Order's language regarding the
          treatment of the PWEC Assets for Track B purposes (see the last bullet
          point under "Track A Order" above) appears to postpone a decision
          regarding the inclusion of the PWEC Assets in APS' rate base, thereby
          effectively precluding the consolidation of the PWEC Assets at APS
          under a common financial and regulatory regime.

     *    APS stated that it did not intend or desire to foreclose the
          possibility that it would acquire all or part of the PWEC Assets or
          that it may propose that the PWEC Assets be included in APS' rate base
          or afforded cost-of-service regulatory treatment to the extent the
          PWEC Assets are used by APS customers. APS stated that these issues
          would be appropriate topics in APS' 2003 general rate case and noted
          that the Track A Order specifically stated that the ACC would not
          pre-judge the eventual rate treatment of the PWEC Assets (see the
          Track A Order, tenth Ordering Paragraph).

                                       2

     *    APS stated that the Track A Order's reversal of the generation asset
          transfer requirement and the resulting bifurcation of generation
          assets between APS and PWEC under different regulatory regimes results
          in PWEC being unable to attain investment grade credit ratings. This,
          in turn, precludes PWEC from accessing capital markets to refinance
          the bridge financing provided by the Company to fund the construction
          of the PWEC Assets or from effectively competing in the wholesale
          markets. APS noted that PWEC had previously received investment grade
          credit ratings contingent upon its receipt of APS generation assets,
          and that the Company's credit ratings could be adversely affected if
          PWEC is unable to finance its capital requirements.

     *    APS stated that the amount of the requested loan and/or guarantee is
          APS' present estimate of the amount of credit support necessary
          through APS to restore PWEC and the Company to their credit status
          prior to the ACC's issuance of the Track A Order. APS further stated
          that if the requested amount proves to be inadequate, APS reserves the
          right to submit a second financing application seeking additional
          credit support.

     *    APS requested ACC approval of the requested loan and/or guarantee by
          December 31, 2002.

     The Company cannot currently predict the outcome of the matters discussed
in this Report, and continues to evaluate its legal and regulatory options.
