Gas Plant Preventive Maintenance
Preventive maintenance (PM) consists of servicing and data collection activities carried out at predetermined intervals and is intended to reduce the likelihood of equipment failures. Due to the importance of PM to the reliable operation of TVA's generating assets and as a result of findings identified related to nuclear and coal PM in previous evaluations, we initiated an evaluation of TVA's gas plant PM to determine if PM had been performed in accordance with established schedules and, if not, what effect the deviations had.
