United Clay Substation - 138 kV Operational Substation in the United States

United Clay Substation is an operational electrical substation located in the United States, with coordinates 35.145744, -96.614693. The facility operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure, supporting local grid connectivity and load balancing. As a substation in the United States, it operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for reliability and market oversight. The 138 kV voltage class is common for regional transmission systems, often linking higher-voltage transmission lines to distribution networks. The substation's location in a rural or semi-urban area of Oklahoma suggests it serves local industrial, agricultural, or residential loads. Its operational status indicates ongoing contribution to grid resilience and power delivery, aligning with sector standards for safety and automation (e.g., IEC 61850).

The substation is situated in a region with a mix of grasslands and agricultural land, typical of central Oklahoma. Its 138 kV voltage level indicates moderate environmental footprint, with electromagnetic fields and land use being primary considerations. The facility's rural setting reduces direct impact on dense populations, but its role in grid stability supports broader environmental goals of reliable power delivery.
