Tronox Substation - 161 kV Industrial Substation in Mississippi, United States

Tronox Substation is an operational electrical substation located in Mississippi, United States, owned and operated by Tronox, LLC. The facility operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for industrial substations supporting large-scale manufacturing operations. The substation 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 transmission and sub-transmission assets. In the United States, substations at this voltage level are often integral to regional grid stability, particularly in areas with significant industrial load. As a dedicated substation for Tronox, a major chemical and mining company, this facility likely plays a key role in ensuring reliable power supply to critical industrial processes. Its location in Mississippi places it within the Southeastern Electric Reliability Council (SERC) region, which oversees grid reliability across the southeastern United States.

The substation is situated in a rural area of Mississippi, where the local grid infrastructure supports both residential and industrial loads. The 161 kV voltage level indicates it is part of the sub-transmission network, which can impact local land use and wildlife corridors. Substations of this type typically require cleared land and may involve oil-filled equipment, necessitating spill prevention measures. The surrounding environment includes mixed forest and agricultural land, common in the region.
