Transmission Condition of Assets

Report Information

Report Type
Inspection / Evaluation
Description
The Tennessee Valley Authority (TVA) owns and operates more than 16,400 miles of transmission lines to deliver electricity to 10 million people in the Tennessee Valley.  TVA has delivered 99.999 percent reliability since the year 2000 and continued investment in its transmission system helps TVA meet the daily challenge of moving power to where it is needed.  Due to the importance of transmission assets to system reliability and the risk associated with the degradation of transmission assets, we performed an evaluation to determine if Transmission (1) is assessing the condition of its transmission assets and (2) has plans in place to address asset degradation.  We determined Transmission is assessing the condition of its assets and has plans in place to address asset degradation.  However, according to the fiscal year 2024 Transmission Long-Term Asset Study, TVA faces increased risk to reliability over the next 10 years based on planned spending levels.
