Overview
Hefner Substation is an operational electrical substation in Oklahoma, United States, owned and operated by Oklahoma Gas & Electric. It operates at a voltage of 138 kV, serving the regional power grid.
Hefner Substation is an operational electrical substation located in Oklahoma, United States. Owned and operated by Oklahoma Gas & Electric, it is a key node in the local power transmission network. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level infrastructure in the region. As part of the U.S. electrical grid, Hefner Substation falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure the stability and security of the bulk power system. The substation likely employs modern switchgear and protection systems compliant with industry standards such as IEEE C37. The substation plays a critical role in distributing electricity to residential, commercial, and industrial customers in the Oklahoma City metropolitan area. Its operational status contributes to grid reliability and supports the region's energy needs. Oklahoma's electrical infrastructure is part of the Southwest Power Pool (SPP) regional transmission organization, which coordinates grid operations across multiple states.
Environmental context
The substation is located in an urban area of Oklahoma, where the local environment is characterized by a mix of residential and commercial development. The 138 kV voltage level indicates it serves as a distribution substation, stepping down power for local use. Environmental considerations for such facilities include electromagnetic field management, oil containment for transformers, and noise mitigation. The site's proximity to urban areas necessitates compliance with local zoning and environmental regulations to minimize impact on surrounding communities.
