Northeast Johnson City 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 for much of the Tennessee Valley region. The substation operates at a voltage of 161 kV, which is a common transmission-level voltage in the US, indicating its role in the high-voltage grid. 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 and oversee interstate electricity transmission. TVA, as a federally owned corporation, also adheres to its own internal standards and policies. The 161 kV voltage level places this substation in the medium-to-high voltage range, typical for regional transmission and distribution. As part of TVA's extensive network, Northeast Johnson City Substation plays a critical role in maintaining grid stability and delivering reliable electricity to the surrounding area. Its location in northeastern Tennessee supports the local community and industrial activities. The substation's operational status ensures continued service to the region, contributing to the overall resilience of the electrical infrastructure.
