Coalmont Substation - Tennessee Valley Authority 161 kV Substation in Tennessee

Coalmont Substation is an operational electrical substation located in Tennessee, United States. It is owned and operated by the Tennessee Valley Authority (TVA), a major federal utility that manages the electric power system across the Tennessee Valley region. The substation operates at a voltage of 161 kV, placing it in the high-voltage transmission category, which is critical for regional grid stability and power distribution. As part of TVA's extensive transmission network, Coalmont Substation is subject to NERC reliability standards and FERC regulation, ensuring compliance with grid security and operational protocols. The 161 kV voltage level is typical for sub-transmission or transmission substations that connect bulk power sources to local distribution networks. TVA's infrastructure is known for its robust design and integration with the broader Eastern Interconnection grid. The substation plays a key role in delivering reliable electricity to the surrounding communities in rural Tennessee. Its location in a mountainous area near the Cumberland Plateau presents unique environmental considerations, such as terrain challenges and vegetation management for right-of-way clearance. TVA's operations emphasize environmental stewardship, including wildlife protection and erosion control measures.

Located in the Cumberland Plateau region of Tennessee, Coalmont Substation operates in a rural, forested area with diverse topography. The substation's 161 kV transmission lines traverse wooded terrain, requiring vegetation management to prevent outages and reduce wildfire risk. TVA implements integrated vegetation management practices to maintain clearance while preserving local ecosystems. The area's steep slopes and clay soils necessitate erosion control measures during construction and maintenance activities.
