Guntown Substation - TVA 161 kV Electrical Substation in Mississippi

Guntown Substation is an operational electrical substation located in Mississippi, United States. Owned and operated by the Tennessee Valley Authority (TVA), it is a medium-voltage facility operating at 161 kV, which is typical for sub-transmission and distribution-level infrastructure in the region. 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. TVA, a federally owned corporation, manages a large integrated power system across the Tennessee Valley, and Guntown Substation plays a role in distributing power to local communities and industries. As part of TVA's extensive transmission network, Guntown Substation contributes to grid stability and reliability in northeastern Mississippi. Its 161 kV voltage level supports the interconnection of local distribution systems and helps meet the electricity demands of the surrounding area, including residential, commercial, and industrial customers.

The substation is located in a rural area of Mississippi, where the surrounding landscape includes agricultural land and forested patches. Electrical infrastructure at this voltage level typically has a localized environmental footprint, with considerations for electromagnetic fields and land use. The facility's operation aligns with TVA's environmental stewardship practices, which include vegetation management and wildlife protection measures.
