Background

Southern California Edison Company (SCE) initially included the cost of this replacement and refurbishment work to the turbines (approximately $9.2 million, 2004 dollars) in the much larger steam generator replacement program's cost estimate (approximately $680 million, 2004 dollars). This turbine project component was so small that Decision (D.) 05-12-040 does not mention it in any one of the 210 findings of fact. SCE, however, has removed this turbine-related work from the steam generator replacement program, and has decided to complete the work as part of the separate high-pressure turbine retrofit project for the San Onofre Generating Station Units 2 & 3 (SONGS), scheduled for completion in 2012. This latter project was included in its most recent test year 2009 general rate case, Application (A.) 07-11-011.¹ SCE indicates that it does not want to "double-recover" the costs for the initial turbine replacement and refurbishment tasks along with the replacement of the steam generators when these former costs are now included in the 2009 and 2012 test year general rate cases.

¹ SCE submitted testimony providing the capital forecast from 2007-2011 for the SONGS two portion of the high-pressure turbine retrofit project, which the Commission approved in D.09-03-025 (Test Year 2009 general rate case decision). See A.07-11-011, Ex. SCE-02, Volume 5.
