4. Utility Retained Generation (URG)

This decision addresses SCE's Record Period URG operations and fuel procurement activities related to nuclear generation, hydroelectric (hydro) generation, coal generation, peakers, and Catalina diesel operations. Both SCE and DRA provided testimony in each of these areas. In its testimony, DRA identified three peaker plant generation outages, four nuclear generation outages and two hydro generation outages, which were determined by DRA to be unreasonable. At that time, DRA recommended that the Commission disallow $25,753,510, which is the amount DRA calculates that SCE paid for additional purchased power in order to compensate for lost power resulting from these outages. In its rebuttal testimony, SCE addressed each identified "unreasonable" outage as well as DRA's calculation of replacement power costs.

In its opening brief, DRA recommends disallowances of $1,516,417 associated with a San Onofre Nuclear Generating Station (SONGS) Unit 2 outage, $49,456 associated with an outage at the Four Corners coal plant, $10,240,844 associated with an outage at the Big Creek 3 hydroelectric plant, and $7,691,411 associated with an outage at the Mammoth Pool Generator. In total, DRA recommends disallowances of $19,498,188. DRA has withdrawn its recommendation for disallowances associated with the other outages identified in its testimony.
