Kosciuko Substation - 161 kV Electrical Substation in the United States

Kosciuko Substation is an operational electrical substation located in the United States, with coordinates 33.030726, -89.600764. The facility operates at a voltage of 161 kV, classifying it as a high-voltage substation critical for transmission-level power distribution. As part of the U.S. electrical grid, it supports the reliable delivery of electricity to surrounding areas. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for bulk power systems. The 161 kV voltage level is typical for subtransmission or transmission applications, connecting generation sources to distribution networks. The facility's equipment likely includes circuit breakers, transformers, and switchgear compliant with standards such as IEEE C37. Kosciuko Substation contributes to the operational resilience of the local power grid, ensuring stable voltage and frequency. Its location in Mississippi supports both urban and rural electricity needs, and its age and maintenance status are key factors in long-term reliability. The substation's role in the regional energy infrastructure underscores its importance for community and industrial power supply.

The substation is situated in a rural area of Mississippi, where the surrounding landscape includes agricultural fields and forests. The 161 kV voltage level indicates a moderate environmental footprint, with potential impacts from electromagnetic fields and land use for transmission corridors. The facility's operation is subject to environmental regulations under the National Environmental Policy Act (NEPA) and state-level requirements for siting and maintenance.
