Hohenwald Substation - 161 kV TVA Electrical Substation in Tennessee

Hohenwald Substation is an operational electrical substation located in Tennessee, United States, and operated by the Tennessee Valley Authority (TVA). The facility operates at a voltage of 161 kV, placing it within the high-voltage transmission category, which is critical for bulk power transfer across the region. The substation is part of TVA's extensive transmission network, which serves approximately 10 million people in the Tennessee Valley. As a 161 kV facility, it likely connects local distribution systems to the larger grid, ensuring reliable electricity delivery. The substation adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) regulation for transmission-level assets. Hohenwald Substation plays a key role in maintaining grid stability in rural Tennessee, supporting both residential and industrial loads. Its operation under TVA, a federally owned corporation, ensures compliance with stringent safety and reliability protocols. The facility's location in a rural area underscores its importance in extending grid access to less densely populated regions.

The substation is situated in a rural area of Tennessee, where the surrounding landscape includes forests and agricultural land. Electrical infrastructure in such settings must balance operational efficiency with minimal environmental disruption, often involving vegetation management and wildlife protection measures. The 161 kV voltage level indicates moderate electromagnetic field exposure, which is managed through standard siting and shielding practices.
