Overview
Pulaski District Substation is an operational electrical substation in Tennessee, USA, owned and operated by the Tennessee Valley Authority (TVA) at 161 kV voltage level.
Pulaski District Substation is an operational electrical substation located in Tennessee, United States. It is owned and operated by the Tennessee Valley Authority (TVA), a major federal utility serving the Tennessee Valley region. The substation operates at a voltage of 161 kV, classifying it as a high-voltage transmission substation critical for regional grid stability. The substation's technical specifications include a voltage level of 161,000 volts, typical for TVA's transmission network. As part of TVA's infrastructure, it adheres to NERC reliability standards and FERC regulations for bulk power system operation. The facility likely employs modern switchgear and protection systems to ensure safe and reliable power distribution. Environmentally, the substation supports the electrical infrastructure of the Tennessee Valley, an area with diverse geography including rivers and forests. Its role in the grid helps integrate power from TVA's generation assets, including hydroelectric, nuclear, and fossil fuel plants, to serve residential, commercial, and industrial customers. The substation's location in a rural area may reduce environmental impact compared to urban installations.
Environmental context
The substation is situated in a rural area of Tennessee, surrounded by mixed forest and agricultural land. Its operation at 161 kV indicates it is a key node in the regional transmission grid, facilitating power flow from TVA's generation sources to local distribution networks. The environmental impact is typical for substations, including electromagnetic fields and land use, but mitigated by TVA's compliance with environmental regulations.
