Gainesboro Substation - 161 kV Electrical Substation in Tennessee, United States

Gainesboro Substation is an operational electrical substation located in Tennessee, United States. It is owned and operated by Upper Cumberland Electric Membership Corporation, a rural electric cooperative serving the Upper Cumberland region. The substation operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for regional transmission and distribution interconnection points. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. As a 161 kV facility, it plays a role in stepping down transmission-level power for local distribution or interconnecting with other grid assets. The equipment likely includes circuit breakers, transformers, and switchgear compliant with IEEE standards. Environmentally, the substation is situated in a rural area of Jackson County, Tennessee, where it supports the electrical needs of the surrounding community. Its operation is critical for maintaining grid stability and reliability in the region, particularly during peak demand periods. The facility contributes to the resilience of the local power supply, serving residential and commercial customers in the Upper Cumberland area.

The substation is located in a rural area of Tennessee, where the surrounding landscape includes farmland and forests. The 161 kV voltage level indicates it is part of the regional transmission network, which may have corridors that affect local habitats. Substations typically have minimal direct environmental impact beyond land use and potential electromagnetic fields, but they are essential for integrating renewable energy sources and supporting grid reliability.
