Chilhowee Substation - Operational 161 kV Electrical Substation in the United States

Chilhowee Substation is an operational electrical substation located in the United States, with coordinates 35.560242, -84.103973. The facility operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations. As a substation, it serves as a node in the electrical grid, stepping voltage levels for efficient power transmission and distribution to local consumers. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards and FERC oversight for transmission-level assets. The facility is part of the broader interconnected grid that ensures reliable electricity supply. The 161 kV voltage level is commonly used for regional power distribution, connecting larger transmission lines to local distribution networks. Chilhowee Substation contributes to the electrical infrastructure of the region, supporting grid stability and power delivery to nearby communities. Its operational status indicates active participation in the energy network, and its location in the southeastern United States places it within a region with diverse energy sources and growing demand. The substation's role is critical for maintaining reliable electricity service and integrating renewable energy sources as the grid evolves.

The substation is located in a rural area of eastern Tennessee, near the Chilhowee Mountain range. The surrounding landscape includes forests and agricultural land, which may be sensitive to electromagnetic fields and habitat fragmentation from power lines. Substations at this voltage level typically require clearances and vegetation management, which can impact local ecosystems. However, proper siting and mitigation measures help minimize environmental effects.
