Business Context and Reporting Period
Company: AVISTA CORP
Filing Type: Form 8-K (Current Report)
Date of Report: December 20, 2024
Event: Issuance of orders by the Washington Utilities and Transportation Commission (WUTC) regarding multi-year electric and natural gas general rate cases filed in January 2024.
Key Financial Metrics and Rate Adjustments
The WUTC orders establish new base revenue levels effective January 1, 2025, with specific adjustments for Rate Year 1 and Rate Year 2.
| Category | Rate Year 1 (2025) | Rate Year 2 (2026) |
|---|---|---|
| Electric Base Revenue Increase | $11.9 million (2.0%) | $44.4 million (7.5%) |
| Natural Gas Base Revenue Increase | $14.2 million (11.2%) | $4.0 million (2.8%) |
| Approved Return on Equity (ROE) | 9.8% | |
| Common Equity Ratio | 48.5% | |
| Rate of Return on Rate Base | 7.32% |
Material Changes and Variance Analysis
The approved electric rate increases differ significantly from the Company's original request of a $77.1 million increase for Rate Year 1. Key drivers for this variance include:
- Power Supply Costs: A $55.7 million decrease in approved power supply costs compared to the original request.
- Return on Equity: A lower approved ROE than requested.
- Colstrip Expenses: The Rate Year 2 increase reflects a $68.9 million approval partially offset by a $24.5 million decrease due to the expiration of a separate tariff for collecting remaining Colstrip expenses by December 31, 2025.
The Commission did not approve the request to modify the Energy Recovery Mechanism but maintained support for wildfire and insurance balancing accounts and decoupling.
