Cerulean Substation - TVA 69 kV Substation in the United States

Cerulean 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 level of 69 kV, classifying it as a medium-voltage substation that plays a role in local power distribution and transmission. As a TVA asset, Cerulean Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security, with compliance requirements for voltage regulation, protection systems, and maintenance protocols typical for substations of this scale. This substation contributes to the electrical infrastructure serving the surrounding region, supporting residential, commercial, and industrial loads. Its location in the TVA service territory places it within a well-established grid network that prioritizes system stability and resilience.

The substation is located in a rural area of western Kentucky, near the town of Cerulean. The surrounding landscape is primarily agricultural, with low population density. The 69 kV voltage level indicates a distribution-class substation, which typically has a smaller environmental footprint compared to high-voltage transmission substations. Standard environmental considerations include stormwater management, oil containment for transformers, and wildlife protection measures.
