Sumrall Substation - Mississippi Power Electrical Substation in Mississippi

Sumrall Substation is an operational electrical substation located in Mississippi, United States. Owned and operated by Mississippi Power, a subsidiary of Southern Company, this facility plays a key role in the regional electrical infrastructure. The substation operates at voltage levels of 46 kV and 4 kV, indicating its function in both sub-transmission and distribution within the local power grid. As part of the U.S. electrical grid, Sumrall Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for transmission and distribution assets. The substation's voltage levels suggest it serves as a distribution substation, stepping down power for local communities and industries in the Sumrall area. The substation's location in rural Mississippi underscores its importance in providing reliable electricity to less densely populated regions. Its operational status ensures continued service to residential, commercial, and agricultural customers. The facility's integration with Mississippi Power's broader network contributes to grid resilience and energy delivery in the region.

The substation is situated in a rural area of Mississippi, characterized by mixed forest and agricultural land. Its operation involves electromagnetic fields and potential impacts on local wildlife, though standard mitigation measures are typically employed. Substations of this scale generally have moderate environmental footprints, with oil-filled transformers requiring careful management to prevent leaks.
