SE 15th Substation - 138 kV Operational Substation in the United States

SE 15th Substation is an operational electrical substation located in the United States, with coordinates 35.4490, -97.3498. Operating at a voltage of 138 kV, it is classified as a high-voltage substation, typically serving transmission-level functions within the electrical grid. The facility is part of the broader North American power infrastructure, which is regulated by NERC reliability standards and FERC oversight for interstate transmission. As a 138 kV substation, SE 15th Substation falls within the typical range for sub-transmission or distribution voltage levels, often connecting bulk power systems to local distribution networks. In the United States, such facilities are subject to stringent reliability standards under NERC, ensuring grid stability and resilience. The substation likely includes switchgear, transformers, and protection systems that comply with industry standards like IEEE C37 for high-voltage equipment. The operational significance of SE 15th Substation lies in its contribution to the local electrical grid, supporting power delivery to residential, commercial, or industrial consumers in the region. Its location in the central United States places it within a grid that experiences diverse weather conditions, requiring robust design for reliability. The facility's role in maintaining voltage stability and power flow is critical for the surrounding community's energy needs.

The substation is situated in a region with a temperate continental climate, characterized by hot summers and cold winters. The surrounding area is primarily urban or suburban, with the substation's footprint potentially impacting local land use. Electrical infrastructure like this can influence electromagnetic fields and require vegetation management to maintain clearance. The facility's operation aligns with grid reliability standards that consider environmental factors such as storm resilience and thermal limits.
