Ozark Substation - 161 kV Electrical Substation in Arkansas, United States

Ozark Substation is an operational electrical substation located in Arkansas, United States, owned and operated by the Southwestern Power Administration (SWPA). As a 161 kV facility, it plays a key role in the regional transmission network, facilitating the distribution of electricity across the area. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), ensuring compliance with reliability standards for bulk power systems. SWPA, a federal power marketing administration, manages this asset as part of its mission to deliver reliable, low-cost hydropower and transmission services. Environmentally, the substation supports grid stability in a region prone to severe weather, including tornadoes and ice storms. Its location in a rural area minimizes direct environmental impact, while its role in the power grid helps integrate renewable energy sources and maintain service continuity for communities.

The substation is situated in a rural area of Arkansas, where the local environment includes forested hills and agricultural land. The 161 kV voltage level indicates a medium-scale facility critical for regional grid stability. Its operation supports the integration of renewable energy, such as wind and solar, while minimizing land use impact through existing infrastructure corridors.
