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 Arizona Public Service Company
(the "Company"), dated August 27, 2002. A copy of the Track A Order is attached
to this Report as Exhibit 99.1. The Company 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 the Company 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 the Company's transfer of its generating assets, and
          directed the Company 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 the Company 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 the Company 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 [the Company] may
          acquire from PWEC shall not be counted as [the Company's] assets in
          determining the amount, timing and manner of the competitive
          solicitation" for Track B purposes, thereby bifurcating the regulatory
          treatment of the Company's existing 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 the Company
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 the Company wished to acquire PWEC's
generating assets, as suggested in a letter the Company filed with the ACC on
July 11, 2002, the Company must file an appropriate application with the ACC. On
September 16, 2002, the Company filed an application with the ACC (the
"Financing Application") requesting the ACC to allow the Company 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:

     *    The Company 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 the Company's generation assets under a common financial and
          regulatory regime. The Company 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 the Company's rate base, thereby effectively precluding the
          consolidation of the PWEC Assets at the Company under a common
          financial and regulatory regime.

     *    The Company 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 the Company's
          rate base or afforded cost-of-service regulatory treatment to the
          extent the PWEC Assets are used by the Company's customers. The
          Company stated that these issues would be appropriate topics in the
          Company's 2003 general rate case and noted that the Track A Order
          specifically stated that the ACC would not pre-judge the eventual rate

                                       2

          treatment of the PWEC Assets (see the Track A Order, tenth Ordering
          Paragraph).

     *    The Company stated that the Track A Order's reversal of the generation
          asset transfer requirement and the resulting bifurcation of generation
          assets between the Company 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. The Company noted that PWEC had previously received
          investment grade credit ratings contingent upon its receipt of the
          Company's generation assets, and that the Company's credit ratings
          could be adversely affected if PWEC is unable to finance its capital
          requirements.

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

     *    The Company 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.
