Item 8.01. Other Events

     APS General Rate Case and Power Supply Adjustor

     On April 27, 2007, an administrative law judge (“ALJ”) with the Arizona Corporation Commission (the “ACC”) issued a recommended order in connection with (a) Arizona Public Service Company’s (“APS”) general retail rate case pending before the ACC and (b) APS’ application to recover through a surcharge approximately $45 million of deferrals under its power supply adjustor (“PSA”) related to unplanned 2005 Palo Verde outages. For additional information regarding APS’ rate request and the PSA, see “APS General Rate Case” and “Power Supply Adjustor” in Note 3 of Notes to Consolidated Financial Statements in the Pinnacle West Capital Corporation/APS Annual Report on Form 10-K for the fiscal year ended December 31, 2006 (“Note 3”). The recommended order and related ACC press release are attached to this report as Exhibits 99.1and 99.2, respectively. The following discussion addresses key aspects of the recommended order and is qualified in its entirety by reference to the recommended order.

     The ALJ recommended an increase of approximately $286 million, or 13.5%, in APS’ annual base retail revenues, which includes a fuel-related increase of approximately $280 million and non-fuel related increases of approximately $6 million. The ALJ recommended that the rate increase take effect June 1, 2007, at which time the interim PSA adjustor approved on May 1, 2006 would terminate. See “Interim Rate Increase” in Note 3 for additional information regarding the interim PSA adjustor. The ALJ’s recommended rate increase is based on a return on equity of 10.75%; a 45%/55% long-term debt/common equity capital structure; a weighted-average cost of capital of 8.32%; an original cost rate base of $4.4 billion; and a base rate for fuel and purchased power costs of $0.0312 per kilowatt-hour (“kWh”).

     The ALJ recommended various modifications to the PSA, including the following: (a) the annual PSA adjustor would be established based on projected, rather than historical, fuel and purchased power costs; (b) the 90/10 sharing arrangement under which APS absorbs 10% of retail fuel and purchased power costs above the base rate and retains 10% of the benefit below the base rate would be modified to exclude certain costs, such as renewable energy resources and the fixed element of long-term purchase power agreements acquired through competitive procurement; (c) the cumulative plus or minus $0.004 per kWh limit from the base fuel amount over the life of the PSA would be eliminated, while the maximum plus or minus $0.004 per kWh limit to changes in the adjustor rate in any one year would remain in effect; and (d) there would not be a preset annual limit on the amount of fuel and purchased power costs that could recovered through base rates and the PSA. The ALJ recommended that the modified PSA take effect June 1, 2007 based on the difference between APS’ proposed 2007 projected fuel and purchased power costs of $0.0325 per kWh and the base fuel rate of $0.0312 per kWh.

     The ALJ recommended that the ACC not adopt any of APS’ additional recommendations to improve APS’ financial metrics (accelerated depreciation, inclusion of construction work in process in rate base, and an “attrition adjustment”).

     The ALJ recommended (a) the disallowance of approximately $14 million, including accrued interest ($8 million after income taxes), of the PSA deferrals related to unplanned 2005 Palo Verde outages and (b) the recovery by APS of the balance of the PSA deferrals (approximately $34 million) over a twelve-month period through a temporary PSA surcharge to be effective concurrently with the implementation of new rates. As of May 1, 2007, these deferrals are expected to total approximately $48 million, including accrued interest. The ALJ also recommended that the ACC require APS and the ACC staff to develop a set of “nuclear performance standards” for the ACC to consider in a separate proceeding.

     APS and other parties to the rate case may file exceptions to the recommended order no later than May 15, 2007. APS is currently evaluating the recommended order and expects to file its exceptions to the ALJ’s recommendations by that date. After the exceptions have been filed by APS and the other parties, the ACC will then consider the ALJ’s recommended order and the exceptions. We cannot predict the timing or the outcome of this rate case or the resulting levels of regulated revenues.
