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 February 23, 2006. The filing addresses operational issues at the Palo Verde Nuclear Generating Station.
Key Financial Metrics and Operational Status
- Operational Status: Unit 1 of the Palo Verde Nuclear Generating Station has been operating at reduced power levels (approximately 25%) since December 25, 2005, due to a non-safety related acoustic impact in a shutdown cooling line.
- Incremental Costs (Historical): To date, the reduced power level has resulted in incremental monthly replacement power costs of approximately $10 million after income taxes.
- Incremental Costs (Projected): Based on lower current forward market energy prices, APS estimates future monthly incremental replacement power costs will be less than $7 million after income taxes.
- Other Metrics: The filing does not provide data on total revenue, net profit, cash flow, margins, debt, or liquidity.
Material Changes and Unusual Items
A potential solution to restore full power, preliminarily scheduled for February, was canceled following a comprehensive analysis that concluded the desired improvement would likely not be achieved. The company is currently evaluating other potential solutions. The primary unusual item is the ongoing reduction in power generation capacity and the associated increase in replacement power costs.
Guidance, Outlook, and Risks
Management is actively evaluating alternative solutions to resolve the acoustic impact issue at Palo Verde Unit 1. The outlook indicates that while replacement power costs remain elevated, they are expected to decrease from the $10 million monthly level to under $7 million monthly due to favorable forward market energy prices. The filing does not provide specific long-term guidance or discuss other material risks beyond the immediate operational constraint.
