Overview
Casky Substation is an operational electrical substation in the United States, owned and operated by the Tennessee Valley Authority. It operates at a voltage of 161 kV, serving the regional power grid.
Casky 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 of 161 kV, classifying it as a high-voltage substation critical for regional power transmission and distribution. TVA is a federally owned corporation that provides electricity to millions of customers across the Tennessee Valley region. As a 161 kV substation, Casky Substation plays a key role in stepping down transmission voltages for local distribution or interconnecting with other grid assets. The facility 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. TVA's substations are typically equipped with modern switchgear and automation systems to ensure grid stability. The substation supports the electrical infrastructure of the surrounding area, contributing to reliable power supply for residential, commercial, and industrial customers. Its location in the Tennessee Valley region places it within a network of TVA's generation and transmission assets, which include hydroelectric, nuclear, and fossil fuel plants. The facility's operational status ensures continued grid connectivity and energy delivery.
Environmental context
The substation is located in a region characterized by mixed urban and rural land use, typical of the Tennessee Valley. Its operation involves electromagnetic fields and potential minor impacts on local wildlife, but modern substations are designed to minimize environmental footprint. The facility's voltage level and role in the grid contribute to efficient power transmission, reducing line losses and supporting renewable energy integration.
