Overview
Coffeeville Substation is an operational electrical substation in Mississippi, United States, owned and operated by the Tennessee Valley Authority (TVA) with a voltage level of 161 kV.
Coffeeville Substation is an operational electrical substation located in Mississippi, 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, which is typical for subtransmission and distribution-level infrastructure, serving to step down power from higher transmission voltages for local distribution. The facility operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. TVA's substations are part of a large, integrated grid that supplies electricity to millions of customers across seven states. The 161 kV voltage level is common for regional power distribution and interconnection with smaller substations and industrial customers. As part of TVA's extensive network, Coffeeville Substation plays a role in maintaining grid stability and reliability in the region. Its location in rural Mississippi supports local communities and industries by providing essential electrical infrastructure. The substation's operational status ensures continued service to the surrounding area, contributing to the overall resilience of the regional power system.
Environmental context
The substation is located in a rural area of Mississippi, where the local environment includes agricultural lands and forested regions. Electrical infrastructure like Coffeeville Substation is designed to minimize environmental impact through proper siting and maintenance practices. The 161 kV voltage level indicates moderate-scale infrastructure that integrates into the landscape with standard environmental considerations for electromagnetic fields and land use.
