Overview
Apalachia Substation is an operational electrical substation in the United States, owned and operated by the Tennessee Valley Authority. It operates at 161 kV, serving the regional grid.
Apalachia Substation is an operational electrical substation located in the United States, owned and operated by the Tennessee Valley Authority (TVA). The facility operates at a voltage of 161 kV, classifying it as a high-voltage substation critical for regional power transmission and distribution. As part of the TVA system, this substation adheres to North American Electric Reliability Corporation (NERC) reliability standards and is subject to Federal Energy Regulatory Commission (FERC) regulation for transmission-level assets. The 161 kV voltage level is typical for subtransmission or distribution substations, supporting grid stability and load delivery in the surrounding area. The substation plays a key role in the local electrical infrastructure, facilitating power flow from generation sources to end users. Its operational status ensures continued reliability for the region, contributing to the overall resilience of the TVA network.
Environmental context
Located in a region with diverse topography, the substation's operation considers local environmental factors such as proximity to water bodies and forested areas. The 161 kV voltage level and rural setting influence maintenance practices and wildlife protection measures, aligning with standard environmental stewardship in electrical infrastructure.
