Calhoun Creek Switching Station: 161 kV Substation in Mississippi, USA

Calhoun Creek Switching Station is an operational electrical substation located in Mississippi, United States. Owned and operated by the Tennessee Valley Authority (TVA), it is part of the high-voltage transmission network that supports the region's power distribution. The facility operates at 161 kV, a common voltage level for subtransmission and distribution substations, indicating its role in stepping down power from higher transmission voltages for local distribution. The substation is regulated under the North American Electric Reliability Corporation (NERC) reliability standards, which ensure the stability and security of the bulk power system. As a TVA asset, it falls under the oversight of the Federal Energy Regulatory Commission (FERC) for transmission-level operations. The facility likely employs modern switchgear and protection systems compliant with industry standards, though specific equipment details are not disclosed. Located in a rural area of Mississippi, the substation supports the electrical infrastructure for surrounding communities and industries. Its operational status ensures reliable power delivery to the local grid, contributing to the overall resilience of the TVA system. The facility's strategic position helps maintain voltage stability and load balancing in the region.

The substation is situated in a rural area of Mississippi, where the surrounding landscape includes agricultural fields and forests. The facility's operation involves electromagnetic fields and potential noise from transformers, which are managed through standard mitigation practices. The site's location away from dense urban centers reduces direct environmental impact, but its role in the grid supports the integration of renewable energy sources and helps reduce transmission losses.
