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

Lawtag Substation is an operational electrical substation located in Louisiana, United States. Owned and operated by Entergy, a major utility company in the region, the facility plays a key role in the local electrical infrastructure. The substation operates at a voltage of 69 kV, which classifies it as a medium-voltage substation typical for distribution and sub-transmission networks. In the United States, substations like Lawtag are subject to regulatory oversight by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for reliability and market operations. Entergy, as the owner and operator, must comply with NERC reliability standards to ensure grid stability. The 69 kV voltage level is commonly used for distributing power from transmission lines to local distribution networks, supporting industrial, commercial, and residential customers. The substation's location in Louisiana places it within a region prone to hurricanes and severe weather, making grid resilience a critical operational consideration. As part of Entergy's network, Lawtag Substation contributes to the reliable delivery of electricity to communities in the area, supporting economic activities and daily life. Its operational status ensures continued service to the regional power grid.

The substation is situated in a region with a humid subtropical climate, characterized by hot summers and mild winters, which influences electrical infrastructure design and maintenance. The area is also subject to hurricane risks, requiring robust infrastructure to withstand extreme weather events. The substation's role in the local grid helps manage power distribution efficiently, reducing transmission losses and supporting energy reliability in the community.
