Hopkinsville Substation - TVA Electrical Substation in Kentucky, USA

Hopkinsville Substation is an operational electrical substation located in Kentucky, United States. It is owned and operated by the Tennessee Valley Authority (TVA), a major federal utility that provides electricity to parts of seven southeastern states. The substation operates at 161 kV, a common sub-transmission voltage level that connects local distribution networks to the higher-voltage transmission grid. As part of TVA's extensive power system, this substation plays a role in stepping down voltage from transmission lines to distribution feeders. The facility is subject to NERC reliability standards and FERC regulation, ensuring grid stability and compliance with federal energy policies. TVA's substations typically employ modern switchgear and protection systems to maintain reliable service. The substation supports the regional electrical infrastructure by facilitating power delivery to residential, commercial, and industrial customers in the Hopkinsville area. Its location in western Kentucky places it within a region with diverse energy sources, including coal, natural gas, and hydroelectric power from TVA's integrated system. The facility contributes to the resilience of the local grid and the broader TVA network.

The substation is situated in a rural area of western Kentucky, where the landscape is primarily agricultural with some forested patches. The local environment is influenced by the nearby Cumberland River and its tributaries. Electrical infrastructure like this substation has minimal direct environmental impact, though its operation supports the integration of renewable energy sources and helps reduce transmission losses by maintaining voltage stability. TVA's environmental stewardship includes managing rights-of-way to protect native vegetation and wildlife habitats.
