Houma Substation - Entergy Louisiana Electrical Substation in Houma, LA

Houma Substation is an operational electrical substation located in Houma, Louisiana, United States. Owned and operated by Entergy Louisiana, the facility plays a key role in the regional power distribution network, stepping down transmission voltages for local use. The substation operates at two voltage levels: 115 kV for transmission and 13.8 kV for distribution, indicating it serves as a step-down substation connecting the high-voltage grid to lower-voltage distribution lines. As part of Entergy Louisiana's infrastructure, it falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards to ensure grid stability. Located in the Gulf Coast region, the substation supports the energy needs of Houma and surrounding areas, which include industrial, commercial, and residential customers. Its role in voltage transformation is critical for maintaining reliable electricity supply, particularly in a region prone to weather-related disruptions. The facility's operational status and integration into Entergy's broader network underscore its importance to local energy resilience.

The substation's location in coastal Louisiana places it in a region vulnerable to hurricanes and flooding, which can impact grid reliability. The 115 kV and 13.8 kV voltage levels suggest it serves both transmission and distribution functions, with potential environmental considerations related to electromagnetic fields and land use. The facility's operation under NERC standards includes vegetation management and equipment maintenance to minimize environmental risks.
