SW 5th Substation - Oklahoma City, United States Electrical Substation

SW 5th Substation is an operational electrical substation located in Oklahoma City, Oklahoma, United States. It serves as a key node in the regional power grid, stepping down transmission-level voltages for distribution to residential, commercial, and industrial customers. The facility operates under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for bulk power systems. The substation's primary technical specifications include voltage levels of 138,000 volts and 69,000 volts, indicating its role in both sub-transmission and distribution networks. Such voltage levels are typical for medium-to-large substations that interconnect high-voltage transmission lines with lower-voltage distribution feeders. The facility likely employs modern switchgear and protection systems, possibly adhering to IEC 61850 standards for substation automation, though specific equipment details are not disclosed. As part of Oklahoma's electrical infrastructure, SW 5th Substation contributes to the reliability of the regional grid, which is managed by the Southwest Power Pool (SPP), a Regional Transmission Organization (RTO). The substation's urban location in Oklahoma City underscores its importance in meeting the electricity demands of a growing metropolitan area. Its operational status ensures continued support for local economic activities and community services.

Located in an urban area of Oklahoma City, the substation's environmental context is shaped by its role in electricity distribution rather than direct ecological impact. The facility's voltage levels and urban siting imply a focus on minimizing electromagnetic field exposure and ensuring safe operation near residential and commercial zones. Typical environmental considerations for such substations include stormwater management, oil containment for transformers, and noise mitigation from equipment.
