McKellar Switching Station - Tennessee Valley Authority Substation in Tennessee

McKellar Switching Station is a substation located in Tennessee, United States, owned and operated by the Tennessee Valley Authority (TVA). As a switching station, it plays a critical role in the electrical infrastructure by routing power at 161 kV, a typical transmission voltage level for regional distribution. The facility operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards. TVA, a federally owned corporation, manages this asset as part of its extensive transmission network serving the Tennessee Valley region. This substation contributes to grid reliability by enabling efficient power flow and voltage control. Its location in Tennessee supports the local energy needs of communities and industries, aligning with TVA's mission to provide affordable and reliable electricity.

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 moderate environmental footprint, with typical considerations for electromagnetic fields and land use. TVA's operations are subject to environmental regulations that manage impacts on local ecosystems.
