Southeast Marshall Substation: 138 kV Electrical Substation in the United States

Southeast Marshall Substation is an operational electrical substation located in the United States, with coordinates 32.522340, -94.351714. The facility operates at a voltage level of 138 kV, which classifies it as a high-voltage substation typically used for transmission and sub-transmission networks. This scale is common for substations serving industrial or urban areas, contributing to the reliability of the local power grid. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce standards for grid reliability and security. As a 138 kV facility, it likely interfaces with both transmission and distribution systems, and may incorporate automation standards such as IEC 61850 for efficient monitoring and control. Environmentally, the substation's location in the southeastern United States places it in a region with moderate climate risks, including thunderstorms and occasional hurricanes. Its role in the grid is critical for maintaining power supply to residential, commercial, and industrial consumers. The facility's operational status ensures continued support for local energy needs and grid resilience.

The substation is situated in a region with a humid subtropical climate, characterized by hot summers and mild winters. The area is prone to severe weather events such as thunderstorms and tornadoes, which can impact grid stability. The 138 kV voltage level indicates the substation's role in transmitting power over moderate distances, serving both urban and rural loads. Its location near Marshall, Texas, suggests it supports local industry and community electricity needs.
