Table Rock Substation is an operational electrical substation located in the United States, owned and operated by the Southwestern Power Administration, a power marketing administration within the U.S. Department of Energy. The substation is situated at coordinates 37.162168, -93.338980, likely in the southwestern Missouri region near Table Rock Lake. As a substation, it plays a critical role in stepping down high-voltage transmission power for distribution or interconnecting different voltage levels within the grid. The substation operates at two voltage levels: 161 kV and 69 kV, indicating it serves both transmission and sub-transmission functions. The 161 kV level is typical for regional transmission, while 69 kV is common for sub-transmission to local distribution networks. As part of the U.S. electrical infrastructure, this facility operates under the regulatory framework of the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards, ensuring grid stability and security. The substation's location near Table Rock Lake suggests it may support hydroelectric power integration or serve rural and suburban loads in the Ozarks region. Its ownership by a federal power agency underscores its role in marketing and transmitting federal hydroelectric power from the Southwestern Power Administration's projects. The facility contributes to the reliable delivery of electricity to communities and industries in the region, supporting economic activity and quality of life.
Environmental context
The substation is located in a region characterized by the Ozark Plateau, with mixed forest and karst topography. Its proximity to Table Rock Lake, a major reservoir, means the facility must consider environmental factors such as stormwater runoff and wildlife corridors. The 161 kV and 69 kV lines traverse rural and potentially wooded areas, requiring vegetation management to prevent outages while minimizing ecological impact. The substation's operation supports the integration of hydroelectric power, a renewable energy source, contributing to lower carbon emissions compared to fossil fuel-based generation.
