Overview
Vardaman Substation is an operational electrical substation in Mississippi, United States, operating at 161 kV. It plays a role in regional power distribution and grid stability.
Vardaman Substation is an operational electrical substation located in Mississippi, United States. The facility operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations that serve industrial and residential areas. 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 the bulk power system. As a 161 kV facility, it likely includes switchgear, transformers, and protection systems compliant with standards such as IEEE C37 for high-voltage equipment. This substation contributes to the electrical infrastructure of Mississippi, supporting local grid reliability and power delivery. Its location in a rural area of Calhoun County suggests it serves agricultural and small community loads, with potential for integration with renewable energy sources as the region modernizes its grid.
Environmental context
The substation is situated in a rural area of Mississippi, characterized by agricultural land and low population density. Its 161 kV voltage level indicates it is part of the sub-transmission network, which typically has lower environmental impact than high-voltage transmission lines. The facility's operation is subject to NERC environmental standards for equipment maintenance and oil containment to prevent soil and water contamination.
