Lafollette Substation | TVA 161 kV Electrical Substation in Tennessee

Lafollette Substation is an operational electrical substation located in Tennessee, United States. Owned and operated by the Tennessee Valley Authority (TVA), it is a key node in the regional transmission network. The substation operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution support. The substation's 161 kV voltage level aligns with common sub-transmission standards in the United States, where TVA manages a large integrated grid across the Tennessee Valley. As a TVA asset, it falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards to ensure grid stability and security. Located in a rural area of eastern Tennessee, the substation supports local electricity distribution and industrial loads. Its role in the TVA system contributes to the reliable power supply for communities and businesses in the region, highlighting its importance in maintaining grid resilience and meeting demand.

The substation is situated in a rural area of Tennessee, where the surrounding landscape includes forests and agricultural land. Electrical infrastructure in such settings typically requires careful siting to minimize visual impact and avoid sensitive habitats. The 161 kV voltage level indicates moderate electromagnetic field exposure, which is managed through standard design practices. TVA's operations are subject to environmental regulations that address land use, wildlife protection, and electromagnetic field guidelines.
