Business Context and Reporting Period
This Form 8-K is a combined current report filed by Pinnacle West Capital Corporation and its subsidiary, Arizona Public Service Company (APS), on August 17, 2006. The filing addresses regulatory developments concerning the recovery of costs associated with unplanned outages at the Palo Verde Nuclear Generating Station in 2005.
Key Financial Metrics
The filing does not provide standard financial statements (revenue, profit, cash flow, or margins) for the reporting period. However, it details specific regulatory financial figures:
- Cost Recovery Request: APS previously requested to recover approximately $45 million via a surcharge over 12 months.
- Proposed Rate Impact: The surcharge represented a temporary rate increase of approximately 1.9%.
- Staff Recommendation: The Arizona Corporation Commission (ACC) staff recommended disallowing approximately $17.4 million of the request.
- Net Impact: The disallowed amount represents approximately $10 million after income taxes.
Material Changes and Regulatory Developments
On August 17, 2006, the ACC staff filed a report recommending the disallowance of a portion of the $45 million cost recovery request. The report alleges that four of the eleven 2005 Palo Verde outages were "avoidable," with three of these directly resulting in the recommended disallowance. The staff found that three outages were due to faulty vendor-supplied equipment, deeming APS's actions not imprudent but recommending an evaluation of legal remedies sought by APS. Additionally, the staff noted that further investigation is required regarding a Unit 1 outage caused by vibration levels in shutdown cooling lines.
Outlook, Management Commentary, and Risks
Management Position: APS disagrees with the staff's recommendation to disallow the costs and plans to contest the finding. Management asserts that the expenses were prudently incurred and recoverable under ACC regulations, which presume investments are prudent unless clear and convincing evidence proves otherwise.
Regulatory Recommendations: The ACC staff recommended establishing minimum nuclear performance standards with penalties, requiring semi-annual operational reports, and mandating equipment management programs.
Procedural Status: The ACC staff requested that these issues be consolidated into APS's general rate case. If granted, hearings scheduled to begin on October 10, 2006, will address these matters. The filing text does not provide a clear value for the final outcome of the rate case or the ultimate financial impact on future periods.
