Hydro Generation Obsolete Equipment

Due to TVA aging equipment and the risk parts would be unavailable, the OIG scheduled a review of Hydro Generation obsolete equipment. The objective of our review was to determine if Hydro Generation was effectively managing obsolete equipment. During our review, we found Hydro Generation could more effectively manage obsolete equipment. We found there was no documented guidance to specify how obsolete equipment should be managed. In addition, we found obsolete equipment had extended outage durations. We also found some equipment condition assessments (ECA) included an "Availability of Spare Parts" indicator, which measures the availability and willingness of the original equipment manufacturer to support existing, installed equipment with parts and service; however, the indicator was not always included in the equipment condition assessments.
