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

Ann Substation is an operational electrical substation located in Louisiana, United States. Owned and operated by Entergy, a major utility company, the facility plays a role in the regional power distribution network. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level infrastructure. As part of the United States electrical infrastructure, Ann Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for the bulk power system, ensuring grid stability and security. The 69 kV voltage level places this substation in a medium-voltage category, often serving industrial or urban load centers. The environmental context of Ann Substation includes its location in southwestern Louisiana, a region characterized by a humid subtropical climate and proximity to the Gulf Coast. The substation's operation supports local electricity demand, which may be influenced by seasonal weather patterns such as hurricane risks. As part of Entergy's network, it contributes to the resilience and reliability of the regional grid.

Ann Substation is situated in southwestern Louisiana, a region with a humid subtropical climate and vulnerability to hurricanes and severe storms. The substation's 69 kV voltage level indicates it serves as a distribution or sub-transmission asset, critical for local grid stability. Its location in a coastal area may require enhanced resilience measures against extreme weather events, though specific design features are not detailed.
