Overview
Terre Haute Water Street Substation is an operational electrical substation in Terre Haute, Indiana, owned and operated by Duke Energy. It operates at 138 kV, serving the local grid.
Terre Haute Water Street Substation is an operational electrical substation located in Terre Haute, Indiana, United States. Owned and operated by Duke Energy, a major utility in the region, this facility plays a key role in the local electrical infrastructure. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level assets in the United States. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. As part of Duke Energy's network, it adheres to NERC's Critical Infrastructure Protection (CIP) standards and FERC's regulations for transmission-level assets. The 138 kV voltage level places it in the medium-to-high voltage range, commonly used for regional power distribution. Located in Terre Haute, a city in western Indiana, the substation supports the electrical needs of the local community and industrial base. Its operational status ensures grid stability and reliability for the area. The facility's role in Duke Energy's system underscores its importance in maintaining consistent power supply to residential, commercial, and industrial customers in the region.
Environmental context
The substation is situated in an urban area of Terre Haute, Indiana, which influences its environmental context. Urban substations like this one are typically designed to minimize visual and noise impacts through screening and sound-dampening measures. The 138 kV voltage level indicates moderate electromagnetic field (EMF) exposure, which is managed through standard setback distances and shielding. The facility's location in a mixed-use area requires careful consideration of land use compatibility and community engagement.
