Business Context and Reporting Period
This Form 8-K Current Report, dated March 28, 2005, is filed by Pinnacle West Capital Corporation and its subsidiary, Arizona Public Service Company (APS). The report details the Arizona Corporation Commission's (ACC) approval of the recommended order in APS's general rate case, incorporating modifications to the 2004 Settlement Agreement.
Key Financial Metrics and Regulatory Terms
The filing does not provide specific revenue, profit, cash flow, or debt figures for the reporting period. Instead, it outlines critical regulatory financial parameters:
- Rate Increase: An annual retail rate increase of approximately 4.21% is approved, effective April 1, 2005.
- Power Supply Adjuster (PSA): APS will record deferrals for fuel and purchased power costs varying from $0.020743 per kWh.
- PSA Limits: Recovery or refund amounts through the PSA are capped at plus or minus $0.004 per kWh over the life of the PSA.
- Cost Cap: The recoverable amount of net fuel and purchased power costs is capped at $776.2 million per year.
- Surcharge Mechanism: If accumulated pretax net deferrals reach $50 million, APS must notify the ACC. A surcharge filing is required before the balance exceeds $100 million. Amounts recovered via surcharge are excluded from the $0.004 per kWh PSA limit.
Material Changes Versus Prior Period
The ACC approved the rate case with specific modifications to the previously recommended order:
- PSA Modifications: Implementation of the specific deferral thresholds and the new surcharge mechanism described above.
- Self-Build Moratorium: The moratorium on generating plants to be in service prior to January 1, 2015, was modified to allow the acquisition of a generating unit or interest from any utility or merchant generator without prior ACC approval.
Guidance, Outlook, and Risks
Outlook and Management Commentary:
- APS does not expect fuel and purchased power costs to exceed the $776.2 million cap in 2005 or 2006.
- The PSA is estimated to result in a 5% rate impact in 2006, separate from the 4.21% base increase.
- Future rates could be further impacted if the ACC approves additional surcharges.
- The acquisition of PWEC Dedicated Assets by APS remains subject to Federal Energy Regulatory Commission (FERC) approval.
Risks and Contingencies:
The filing includes extensive forward-looking statements warning that actual results may differ due to regulatory decisions, industry restructuring, market prices for electricity and natural gas, weather variations, power plant performance, and credit rating uncertainties.
Investor Verification Checklist
- Verify the effective date of the 4.21% rate increase (April 1, 2005).
- Monitor the status of the FERC approval for the acquisition of PWEC Dedicated Assets.
- Track accumulated pretax net deferrals to determine if the $50 million notification or $100 million surcharge filing thresholds are triggered.
- Review future filings for updates on the estimated 5% PSA impact for 2006.
- Assess the impact of the modified self-build moratorium on future capital expenditures and acquisitions.
