Overview
Tuscumbia Substation is an operational electrical substation in the United States. It operates at 161 kV, serving as a key node in the regional transmission grid.
Tuscumbia Substation is an operational electrical substation located in the United States, with coordinates 34.723864, -87.679989. The facility operates at a voltage of 161 kV, classifying it as a high-voltage substation within the transmission network. This scale is typical for substations that interconnect regional power systems and support bulk electricity transfer. The substation operates under the regulatory framework of the United States, which includes reliability standards set by the North American Electric Reliability Corporation (NERC) and oversight by the Federal Energy Regulatory Commission (FERC) for transmission-level assets. The 161 kV voltage level is common for sub-transmission and transmission applications, often serving as a link between higher voltage lines and distribution networks. The facility's location in northwestern Alabama suggests it may be part of the Tennessee Valley Authority (TVA) or a similar regional grid. As a substation, Tuscumbia plays a critical role in grid stability by enabling voltage transformation, switching, and protection of electrical circuits. Its operational status ensures continued reliability for local communities and industries. The facility contributes to the resilience of the regional electrical infrastructure, supporting economic activity and daily life in the area.
Environmental context
The substation is located in a rural area near Tuscumbia, Alabama, within the Tennessee River Valley. The region experiences a humid subtropical climate, with hot summers and mild winters, which can affect equipment performance and maintenance schedules. The facility's operation involves electromagnetic fields and potential oil leakage from transformers, though modern substations are designed with containment measures. The surrounding landscape includes agricultural and forested areas, and the substation's presence supports local energy needs without significant direct environmental impact.
Frequently asked questions
