Chalkley Bulk Substation - Louisiana Electrical Substation Operated by Entergy Louisiana

Chalkley Bulk Substation is a key electrical infrastructure facility located in Louisiana, United States. Owned and operated by Entergy Louisiana, the substation is currently operational and serves as a critical node in the regional power grid. The facility handles multiple voltage levels, including 230 kV, 138 kV, and 69 kV, indicating its role in both high-voltage transmission and sub-transmission. As part of the United States electrical infrastructure, Chalkley Bulk Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security for transmission-level assets. The substation's voltage levels suggest it is a medium to large-scale facility, typical for bulk power transfer and distribution within the Entergy Louisiana service area. The substation plays a vital role in maintaining grid stability and power delivery to the surrounding region. Its location in Louisiana, a state prone to hurricanes and extreme weather, underscores the importance of robust infrastructure for emergency response and grid resilience. The facility contributes to the reliable supply of electricity for residential, commercial, and industrial customers in the area.

The substation is situated in Louisiana, a region characterized by a humid subtropical climate with frequent thunderstorms and hurricane threats. The facility's design likely incorporates measures to withstand extreme weather events, such as elevated equipment and flood protection. The surrounding area includes wetlands and coastal ecosystems, which may influence environmental considerations for infrastructure development and maintenance.
