Transmission, Power Supply and Support – Critical Spare Parts

Due to the importance of having critical spare parts available to reduce the amount of recovery time after events that may affect the transmission system, we conducted an evaluation to determine if Transmission is effectively managing critical spare parts. Transmission manages its critical spare parts as storm restoration material. We determined storm restoration material could be managed more effectively. Specifically, we found (1) discrepancies between storeroom inventory counts and data in TVA’s work management system, (2) storm restoration materials were not properly identified, and (3) storm restoration material reorder points were incorrect. Additionally, Transmission’s Web site contained out-of-date and incomplete data.
