Item 8.01 Other Events

On March 24, 2009, the Nuclear Regulatory Commission (the “NRC”) informed Arizona Public Service Company (“APS”) that it is removing Palo Verde Nuclear Generating Station (“Palo Verde”) Unit 3 from the “multiple/repetitive degraded cornerstone” column of the NRC’s Action Matrix (“Column 4”), removing Units 1 and 2 from the “one degraded cornerstone” column (“Column 3”), and returning all three units of the plant to routine inspection and oversight by the NRC. This notification follows the NRC’s completion of its inspections of the corrective actions taken by Palo Verde to address performance deficiencies that caused the NRC to place Unit 3 into Column 4 and Units 1 and 2 into Column 3. The NRC has closed the confirmatory action letter that outlined the performance deficiencies and associated corrective actions. For additional information, see “Business of Arizona Public Service Company — Nuclear Generating Facility — NRC Inspection” in Item 1 of the Pinnacle West Capital Corporation/APS Annual Report on Form 10-K for the fiscal year ended December 31, 2008, and the NRC’s press release dated March 24, 2009 attached hereto as Exhibit 99.1.
