Smith Mountain Substation - 138 kV Operational Substation in the United States

Smith Mountain Substation is an operational electrical substation located in the United States, with coordinates 37.040270, -79.532488. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation critical for transmission and distribution within the regional grid. As a substation operating under U.S. jurisdiction, Smith Mountain Substation adheres to NERC reliability standards and FERC regulations for transmission-level assets. The 138 kV voltage level is typical for sub-transmission or distribution substations, serving to step down power from higher voltage transmission lines for local distribution networks. The substation's operational status ensures continued support for grid stability and electricity supply to the surrounding area. Its location in a rural or suburban setting likely contributes to serving local communities and industrial loads, underscoring its importance in the regional electrical infrastructure.

The substation's location in the United States places it within a regulatory framework that emphasizes grid reliability and environmental compliance. The 138 kV voltage level indicates a moderate scale of operation, with potential environmental considerations related to electromagnetic fields and land use. The facility's rural or suburban setting may reduce direct impact on sensitive ecosystems, while still supporting essential power distribution.
