Choupique Substation - Louisiana Electrical Substation Operated by Entergy Louisiana

Choupique Substation is an operational electrical substation located in Louisiana, United States. Owned and operated by Entergy Louisiana, the facility plays a role in the regional transmission and distribution network, stepping down voltage for local distribution or interconnecting generation sources. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level infrastructure in the United States. As part of the Entergy Louisiana system, it falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets and must comply with North American Electric Reliability Corporation (NERC) reliability standards to ensure grid stability and security. Located in southwestern Louisiana, the substation supports the electrical infrastructure of the region, which includes industrial, commercial, and residential customers. Its operational status contributes to the reliability of the local grid, particularly in an area prone to weather-related disruptions such as hurricanes. The facility's role in voltage regulation and power distribution is critical for maintaining service continuity.

The substation is situated in a region with a humid subtropical climate, characterized by hot summers and mild winters, which can influence equipment performance and maintenance schedules. The surrounding area includes wetlands and waterways, requiring careful management of stormwater runoff and potential impacts from flooding. The facility's operation involves electromagnetic fields and potential noise, but standard mitigation measures are typically in place to minimize environmental disturbance.
