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.
