Maryville Substation - Operational 115 kV Substation in the United States

Maryville Substation is an operational electrical substation located in the United States, with coordinates 33.347754, -79.297984. The facility operates at a voltage of 115 kV, placing it in the medium-voltage range typical for distribution-level substations that serve local communities and industrial areas. As a substation in the United States, Maryville Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for reliability standards. The facility likely adheres to NERC's Critical Infrastructure Protection (CIP) standards and may be subject to regional transmission organization (RTO) or independent system operator (ISO) requirements, depending on its interconnection. The substation's operational status indicates it is actively contributing to the electrical grid. Its location in the southeastern United States places it in a region with a mix of urban and rural loads, where substations like this are critical for maintaining voltage stability and ensuring reliable power delivery to end-users. The facility's role in the local grid underscores its importance for community energy needs.

The substation is located in a region with a humid subtropical climate, which can affect equipment performance and maintenance schedules. The surrounding area includes both forested and agricultural land, with potential ecological considerations such as stormwater runoff and electromagnetic field effects on wildlife. The facility's voltage level and urban proximity influence its environmental footprint, with typical mitigation measures including oil containment systems and noise barriers.
