Gas Plant Overtime

We determined significant amounts of overtime were worked by employees at some gas plants. Specifically, we determined 69 percent (221,517 hours) of the 318,903 hours of overtime was performed at 7 of the 17 plants. The overtime worked at these 7 plants was the equivalent of 51 full-time employees. We also determined some employees worked significant amounts of overtime. For example, we found 51 instances during fiscal years 2018 and 2019 where employees worked over 1,000 hours of overtime and 2 of these employees had nearly 2,000 hours of overtime in a single year. Additionally, we determined the Tennessee Valley Authority (TVA) may not be accurately capturing the effects of fatigue because (1) fatigue assessments are no longer required when significant overtime is worked and (2) fatigue data is not trended with health and safety data in TVA’s medical case management system.
