Swan Substation - Entergy Louisiana Electrical Substation in Louisiana

Swan Substation is an operational electrical substation located in Louisiana, United States. Owned and operated by Entergy Louisiana, the facility plays a key role in the regional power transmission and distribution network. The substation handles multiple voltage levels, including 69 kV and 13.8 kV, indicating its function in stepping down transmission voltages for local distribution. As part of the U.S. electrical infrastructure, Swan Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and oversee interstate electricity transmission. The substation's voltage levels suggest it serves both sub-transmission and distribution functions, typical for facilities connecting bulk power systems to local grids. The substation's location in Louisiana places it within a region prone to hurricanes and severe weather, which can impact grid stability. Entergy Louisiana, as the owner and operator, is responsible for maintaining reliability and resilience. The facility contributes to the power supply for surrounding communities and industrial customers, supporting the state's energy needs.

Located in Louisiana, Swan Substation operates in a region with a humid subtropical climate and vulnerability to hurricanes and flooding. The substation's design and maintenance must account for these environmental factors to ensure grid reliability.
