Overview
Dumplin Valley Switching Station is an operational substation in Tennessee, United States, owned and operated by the Tennessee Valley Authority. It operates at a voltage of 161 kV, serving the regional power grid.
Dumplin Valley Switching Station is a substation located in Tennessee, United States, and is part of the Tennessee Valley Authority (TVA) electrical infrastructure. TVA is a federally owned corporation that provides electricity for parts of seven southeastern states, making this facility a component of a large, integrated power system. The substation operates at a voltage of 161 kV, which is a common transmission voltage level for regional power distribution. As a switching station, its primary function is to route power and provide switching capabilities within the TVA grid, rather than transforming voltage. The facility is operational and contributes to grid reliability in the region. In the United States, substations like this are subject to NERC reliability standards and FERC regulations, ensuring stable and secure operation of the bulk power system. The environmental context of this substation includes its location in a rural area of eastern Tennessee, near the foothills of the Great Smoky Mountains. The surrounding landscape is characterized by rolling hills and agricultural land, with the substation playing a role in delivering electricity to local communities and industries. Its operation supports the regional economy and residential needs without significant direct environmental impact, as substations typically have a small footprint and are designed to minimize ecological disruption.
