Fontana Substation: TVA 161 kV Electrical Substation in Tennessee

Fontana Substation is an operational electrical substation located in Tennessee, United States. It is owned and operated by the Tennessee Valley Authority (TVA), a federally owned corporation that provides electricity to 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. The substation's 161 kV voltage level indicates its role in the transmission network, connecting generation sources to distribution systems. TVA's infrastructure is regulated by the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. This ensures robust grid management and compliance with mandatory reliability requirements for bulk power systems. As part of TVA's extensive transmission network, Fontana Substation supports the delivery of electricity to communities and industries in the region. Its location in a rural area of Tennessee underscores its importance in maintaining grid connectivity and reliability for the surrounding area. The substation's operational status contributes to the overall resilience of the regional power system.

The substation is situated in a rural area of Tennessee, near the Great Smoky Mountains, which influences local environmental considerations. The 161 kV voltage level and TVA's operational practices align with NERC standards to minimize environmental impact, such as electromagnetic field management and vegetation control. The facility's location away from dense urban centers reduces exposure to sensitive ecological zones while supporting grid reliability.
