Overview
Terre Haute 25th St. Substation is an operational electrical substation in Terre Haute, Indiana, United States. It operates at 34.5 kV, serving local grid stability and distribution needs.
Terre Haute 25th St. Substation is an operational electrical substation located in Terre Haute, Indiana, United States. As a substation, it plays a critical role in voltage transformation and distribution within the local power grid, stepping down transmission-level voltages for residential and commercial use. The substation operates at a voltage of 34.5 kV, which is typical for sub-transmission or primary distribution in the United States. This voltage level indicates its role in distributing power from higher-voltage transmission lines to local feeders. The facility is part of the broader U.S. electrical infrastructure, which is regulated by NERC reliability standards and FERC oversight for grid stability. Located in Terre Haute, the substation supports the electrical needs of the surrounding community, including industrial, commercial, and residential customers. Its operational status ensures continued reliability of power supply in the region, contributing to the overall resilience of the local grid. The facility's location in an urban area underscores its importance in maintaining consistent electricity delivery.
Environmental context
The substation is situated in Terre Haute, an urban area in Indiana with a mix of industrial and residential zones. Its operation at 34.5 kV places it in a medium-voltage range, which is typical for distribution substations. The local environment includes proximity to the Wabash River, and the substation's design likely incorporates standard environmental safeguards for noise and electromagnetic fields. Urban substations like this one are critical for grid reliability but must balance operational needs with community and environmental considerations.
