Item 8.01 – Other Events.
On October 10, 2008, Tucson Electric Power Company (TEP) brought back into service its 380-megawatt Springerville Generating Station Unit 1 (Unit 1) following a 16-day unplanned outage starting on September 24. The outage resulted from a mechanical problem with the turbine. The turbine was successfully replaced with an on-site spare. The Unit 1 turbine is scheduled to be replaced in early 2009; a similar replacement of the Springerville Generating Station Unit 2 turbine was completed in 2007.
TEP estimates the outage cost at approximately $5 million, pretax. The cost includes the replacement power to meet TEP’s retail load, lost opportunity to sell energy into the wholesale market during the Unit 1 outage, and approximately $500,000 of operation and maintenance expense to repair the unit.
