Business Context and Reporting Period
This Form 8-K is a joint current report filed by Pinnacle West Capital Corporation and its subsidiary, Arizona Public Service Company (APS), on February 2, 2006. The filing addresses regulatory actions regarding the recovery of deferred fuel and purchased power costs under the Power Supply Adjustor (PSA) mechanism.
Key Financial Metrics and Events
The filing details a request to recover $59.9 million in costs deferred by APS during 2005. These costs are to be recovered through two separate surcharges:
- Total Deferred Costs: $59.9 million (retail fuel and purchased power costs from 2005).
- Surcharges Requested:
- Surcharges 1: $15.3 million to be recovered over 12 months (approx. 0.66% temporary rate increase).
- Surcharges 2: $44.6 million to be recovered over 12 months (approx. 1.9% temporary rate increase).
- Combined Impact: The overlapping recovery periods would result in a temporary rate increase of approximately 2.6%.
- Related Rate Increase: A separate PSA annual adjustor rate increase of approximately 5% became effective on February 1, 2006, covering other components of the 2005 deferrals.
Material Changes and Regulatory Status
The filing represents a material change in the regulatory status of APS's cost recovery mechanisms. The $44.6 million portion of the deferrals is specifically attributed to replacement power costs resulting from unplanned outages at the Palo Verde Nuclear Generating Station between April 1, 2005, and December 31, 2005. The filing notes that hearings for a pending emergency interim rate case are scheduled to begin on March 20, 2006, which may impact the timing of the first surcharge.
Outlook, Risks, and Contingencies
The recovery of these costs is contingent upon approval by the Arizona Corporation Commission (ACC). The timing of the surcharges is linked to regulatory decisions:
- The first surcharge is proposed to begin upon the ACC's decision in the pending emergency interim rate case.
- The second surcharge is proposed to begin no later than the ACC's completion of its inquiry regarding the 2005 Palo Verde outages.
The filing does not provide specific revenue, profit, cash flow, or debt figures for the reporting period, as the document focuses solely on the regulatory application for surcharges.
Key Facts for Investor Verification
- Verify the ACC's decision timeline regarding the emergency interim rate case and the Palo Verde outage inquiry to determine the effective dates of the surcharges.
- Confirm the final approved surcharge amounts, as the $59.9 million figure represents a request, not a finalized rate adjustment.
- Monitor the impact of the combined 2.6% temporary rate increase and the 5% annual adjustor on customer demand and future revenue projections.
- Review the specific details of the Palo Verde outages to assess the likelihood of future unplanned outage costs.
