Preventive maintenance (PM) includes tasks carried out on a predetermined interval to reduce the likelihood of a failure. Due to the importance of PM on the reliable operation of assets and as a result of findings identified related to nuclear and coal PM in previous evaluations, we initiated an evaluation of the TVA's transmission PM. The objective of our evaluation was to determine if transmission PM was performed in accordance with established schedules and, if not, what effects the deviations had. We could not determine if transmission PM had been performed in accordance with established schedules because (1) work completion dates in Maximo, TVA's work management system, did not consistently match the date the PM was completed, and (2) TVA did not require supporting documentation evidencing work completion dates to be maintained. Additionally, we reviewed documentation related to equipment failures and did not identify any failures or Load Not Served, a measure of the magnitude and duration of transmission system outages, attributed to Transmission and Power Supply PM practices.
