Contraband Substation - Operational 69 kV Substation in Louisiana, United States

Contraband Substation is an operational electrical substation located in Louisiana, United States, operated by Entergy Louisiana. The facility operates at a voltage of 69 kV, placing it in the medium-voltage range typical for distribution-level substations that serve local communities and industrial areas. As part of the Entergy Louisiana network, the substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and compliance with mandatory reliability standards. The 69 kV voltage level is common for sub-transmission and distribution substations that step down power from higher transmission voltages for local distribution. The substation plays a key role in the regional electrical infrastructure, supporting the reliability of power supply in the Lake Charles area. Its operational status contributes to the stability of the local grid, serving residential, commercial, and industrial customers. The facility is part of Entergy's broader efforts to maintain a resilient electrical network in Louisiana.

The substation is located in a region with a humid subtropical climate, which can pose challenges such as heat and humidity affecting equipment performance. The area is also prone to hurricanes and severe storms, making grid resilience critical. The substation's design likely includes measures to withstand extreme weather events, such as elevated equipment and flood protection, to ensure continuous operation during adverse conditions.
