Overview
Little Gypsy Substation is an operational electrical substation in Louisiana, USA, owned by Entergy Louisiana. It operates at 230 kV and 115 kV voltage levels, serving the regional power grid.
Little Gypsy Substation is an operational electrical substation located in Louisiana, United States, owned and operated by Entergy Louisiana. The facility operates at voltage levels of 230 kV and 115 kV, indicating its role in both transmission and sub-transmission within the regional grid. As a substation in the United States, Little Gypsy operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. The facility's dual voltage levels suggest it serves as a critical node for stepping down power from high-voltage transmission lines to distribution networks. The substation's location in Louisiana places it within the Midcontinent Independent System Operator (MISO) market, which coordinates regional grid operations. Its proximity to the Mississippi River and industrial corridors underscores its importance in supporting local industrial and residential electricity demand.
Environmental context
The substation is situated in a region with a humid subtropical climate, which can affect equipment performance and maintenance schedules. Its location near the Gulf Coast exposes it to risks from hurricanes and flooding, necessitating robust infrastructure resilience measures. The facility's role in the grid supports the integration of natural gas and renewable energy sources common in Louisiana's energy mix.
