Tell City Substation - Hoosier Energy 69 kV Substation in Indiana

Tell City Substation is an operational electrical substation located in Indiana, United States. Owned and operated by Hoosier Energy, a generation and transmission cooperative, the facility plays a critical role in distributing electricity across the region. With a voltage level of 69 kV, it is classified as a medium-voltage substation, typical for sub-transmission and distribution networks that connect local utilities to the broader grid. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. Hoosier Energy, as a member of the Midwest Reliability Organization (MRO), ensures compliance with these standards. The 69 kV voltage level is common for regional distribution, and the substation likely includes switchgear and transformers to step down power for local delivery. As part of Hoosier Energy's network, Tell City Substation supports the electrical infrastructure of southern Indiana, contributing to grid stability and reliability for residential, commercial, and industrial customers. Its location in a rural area underscores its importance in serving communities that might otherwise have limited access to reliable power. The substation's operational status ensures continued service to the local economy and population.

The substation is situated in a rural area of southern Indiana, characterized by mixed agricultural and forested landscapes. The 69 kV voltage level indicates a medium-scale facility that integrates into the local grid without significant land use change. The environmental impact is primarily limited to the substation footprint, with potential considerations for electromagnetic fields and habitat fragmentation. Hoosier Energy likely follows standard environmental practices for substation operation, including vegetation management and spill prevention.
