Dickson Substation - Tennessee Valley Authority 161 kV Substation in Tennessee

Dickson Substation is an operational electrical substation located in Tennessee, United States. It is owned and operated by the Tennessee Valley Authority (TVA), a federally owned electric utility corporation. The substation operates at a voltage of 161 kV, placing it in the high-voltage transmission category, which is critical for regional grid stability and power distribution. The substation's technical specifications indicate a 161 kV voltage level, typical for sub-transmission or transmission applications in the US. As part of TVA's network, it adheres to NERC reliability standards and FERC regulations, ensuring grid reliability and security. The facility likely plays a role in stepping down voltage for local distribution or interconnecting with other transmission lines. Operationally, Dickson Substation supports the electrical infrastructure in the Dickson area, contributing to the reliability of power supply for residential, commercial, and industrial customers. Its location in Tennessee, a state with diverse energy mix including hydro, nuclear, and natural gas, underscores its importance in integrating various generation sources into the grid.

The substation is situated in a rural area of Tennessee, where the surrounding landscape includes forests and agricultural land. The 161 kV voltage level indicates it is part of the transmission network, which can have environmental considerations such as electromagnetic field effects and land use for right-of-way corridors. TVA's operations are subject to environmental regulations including the National Environmental Policy Act (NEPA), which may require assessments for new projects or upgrades.
