Greeneville Substation - Tennessee Valley Authority Electrical Substation

Greeneville Substation is an operational electrical substation located in Tennessee, United States. It is owned and operated by the Tennessee Valley Authority (TVA), a major federal utility that manages the electric power system in the Tennessee Valley region. The substation operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations. The substation's technical specifications include a voltage of 161,000 volts, which is common for TVA's sub-transmission network that interconnects with local distribution systems. As part of TVA's extensive grid, Greeneville Substation adheres to North American Electric Reliability Corporation (NERC) reliability standards and is regulated by the Federal Energy Regulatory Commission (FERC). The facility likely employs modern switchgear and protection systems to ensure grid stability and safety. Greeneville Substation plays a critical role in delivering reliable electricity to the Greeneville area and surrounding communities. As part of TVA's integrated power system, it supports the region's industrial, commercial, and residential energy needs. The substation's operational status and voltage level indicate its importance in maintaining grid resilience and meeting local demand.

The substation is located in Greeneville, Tennessee, a region characterized by mixed urban and rural landscapes. The area's electrical infrastructure supports local industries and residential communities. The 161 kV voltage level suggests the substation is part of the sub-transmission network, which typically has lower environmental impact than high-voltage transmission lines. The facility's operation is subject to environmental regulations that manage electromagnetic fields, noise, and stormwater runoff.
