Item 8.01. Other Events

Emergency Interim Rate Increase Order

     On May 2, 2006, the Arizona Corporation Commission (the “ACC”) voted to approve, with certain modifications, the recommended order of the ACC administrative law judge in connection with the application by Arizona Public Service Company (“APS”) for an emergency interim rate increase of $232 million to recover APS’ under-collection of higher annual fuel and purchased power costs. See “Emergency Interim Rate Increase Recommended Order” in Item 8.01 of the Pinnacle West Capital Corporation/APS Current Report on Form 8-K filed with the Securities and Exchange Commission (the “SEC”) on April 21, 2006 (the “April 21 Form 8-K”). Among other things, the order approved by the ACC:

	•		authorizes an interim adjustor under APS’ Power Supply Adjustor (“PSA”), effective May 1, 2006, that will result in an interim retail rate increase of approximately 8.3% designed to recover approximately $138 million of fuel and purchased power costs during 2006. This interim adjustor combined with the PSA surcharge (see “ACC Approval of PSA Surcharge” below) will result in a rate increase of approximately 9.0% designed to recover approximately $149 million of fuel and purchased power costs during 2006;
	•		provides that amounts collected through the retail rate increase “remain subject to a prudency review at the appropriate time” and that “all unplanned Palo Verde outage costs for 2006 should undergo a prudence audit by [the ACC] Staff”;
	•		encourages parties to APS’ general rate case to “propose modifications to the PSA that will address on a permanent basis, the issues with timing of recovery when deferrals are large and growing”;
	•		affirms APS’ ability to defer fuel and purchased power costs above the prior annual cap of $776.2 million until the ACC decides the general rate case; and
	•		encourages APS to diversify its resources “through large scale, sustained energy efficiency programs, [using] low cost renewable energy resources as a hedge against high fossil fuel costs.”

ACC Approval of PSA Surcharge

     On April 12, 2006, the ACC issued an order approving APS’ recovery of $15.3 million of 2005 PSA deferrals through a temporary rate increase of approximately 0.7% to take effect upon the date of the ACC’s decision in the emergency interim rate proceeding discussed above. See “ACC Approval of PSA Surcharge” in the April 21 Form 8-K. As a result of the ACC’s decision described above, this temporary rate increase became effective May 2, 2006.
