Tri-County Tennessee Gas Substation - 115 kV Electrical Substation in the United States

Tri-County Tennessee Gas Substation is an operational electrical substation located in the United States, owned and operated by West Penn Power. The facility operates at a voltage of 115 kV, which is a common transmission-level voltage in the US, indicating its role in stepping down power for distribution or interconnecting regional grids. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards and oversee interstate electricity transmission. As a 115 kV facility, it is likely part of the bulk power system and subject to NERC's Critical Infrastructure Protection (CIP) standards for cybersecurity and physical security. This substation supports grid stability and reliability in its region by facilitating the flow of electricity from generation sources to load centers. Its location in Pennsylvania contributes to the state's diverse energy mix, which includes natural gas, nuclear, and renewables. The facility's operational status ensures continued service to local communities and industries.

The substation is located in rural Pennsylvania, an area characterized by forested hills and agricultural land. Its operation involves minimal direct environmental impact, though the transmission lines and infrastructure may affect local wildlife and habitats. The 115 kV voltage level suggests it is part of the regional transmission network, which can influence land use and ecological connectivity through right-of-way corridors.
