ITEM 5. STATE REGULATORY MATTERS

         On June 27, 2003, Arizona Public Service Company ("APS") filed a
general rate case with the Arizona Corporation Commission ("ACC") and in August
2003 the ACC set April 7, 2004 as the date for the hearing on the rate case to
begin. On December 19, 2003, an intervenor in the rate case representing certain
merchant generators filed a motion requesting that the ACC (i) require APS to
expand its pending request for proposals ("RFP") for long-term power supply
resources to 2200 megawatts and (ii) delay the rate case hearing for four months
to permit the results of the expanded RFP to be considered in the rate case or,
in the alternative, bifurcate the rate case to separately consider issues
regarding Pinnacle West Energy Corporation assets. APS issued the RFP in early
December 2003 for the purchase of at least 500 megawatts of long-term power
supply resources for delivery beginning June 1, 2007 to be used for APS'
anticipated retail load.

         On January 8, 2004, an ACC administrative law judge ("ALJ") issued a
procedural order (the "Procedural Order") (i) revising the schedule for APS'
pending general rate case to delay the hearing and other aspects of the
procedural schedule by about three weeks, and (ii) requiring APS to provide
certain information to potential bidders and to extend the bid response deadline
by one week, but not to change the amount of resources requested in the RFP. The
hearing is currently scheduled to begin on April 26, 2004. A copy of the
Procedural Order is attached hereto as Exhibit 99.1.

         Based on the revised schedule and existing ACC regulations, the ACC
will be able to make a decision in this general rate case in 2004. For
additional information regarding the rate case, see "APS General Rate Case and
Retail Rate Adjustment Mechanisms" in Note 5 of Notes to Condensed Consolidated
Financial Statements in Pinnacle West Capital Corporation's Quarterly Report on
Form 10-Q for the fiscal quarter ended September 30, 2003.
