Business Context and Reporting Period
This Form 8-K is a current report filed by Pinnacle West Capital Corporation and its subsidiary, Arizona Public Service Company (APS), on June 14, 2023. The filing addresses a significant regulatory development regarding the resolution of a 2019 rate case appeal involving the Arizona Corporation Commission (ACC) and the Arizona Court of Appeals.
Key Financial Metrics and Material Changes
The filing does not provide standard financial statements (revenue, profit, cash flow, or debt levels) for a specific reporting period. Instead, it details a proposed financial resolution with the following material components:
- Cost Recovery: Proposed recovery of $215.5 million in costs related to Selective Catalytic Reduction (SCR) equipment at the Four Corners Power Plant on a going-forward basis.
- Return on Equity (ROE): Reversal of a 20 basis point reduction in APS's ROE, allowing for the recovery of resulting revenue until the next rate case.
- Lost Revenue: Recovery of lost revenue incurred between December 2021 and June 2023 due to the SCR disallowance and the ROE reduction.
- Implementation Mechanism: A surcharge to effectuate these recoveries, proposed to become effective on or after July 1, 2023.
Guidance, Outlook, and Risks
Management Commentary and Outlook: The ACC and APS have reached a "Proposed Resolution" and filed a joint notice requesting ACC approval. If adopted, the ACC intends to withdraw its Petition for Review to the Arizona Supreme Court, effectively ending the litigation.
Risks and Contingencies:
- Regulatory Approval: The resolution is contingent upon the ACC commissioners voting to adopt the Proposed Resolution. APS cannot predict the outcome of this vote.
- Supreme Court Action: APS cannot predict any action the Arizona Supreme Court may take if the ACC does not adopt the resolution.
- Withdrawal of Support: If the ACC fails to adopt the material terms, APS reserves the right to withdraw support for the resolution and pursue all available remedies without prejudice.
Investor Verification Checklist
- Verify whether the ACC commissioners have voted to adopt the Proposed Resolution.
- Confirm the effective date of the surcharge and the specific terms of the revenue recovery.
- Monitor the status of the Petition for Review with the Arizona Supreme Court to ensure it has been withdrawn.
- Review future filings for any updates if the ACC fails to adopt the resolution or if the Supreme Court intervenes.
