Alaska Substation is an operational electrical substation located in Louisiana, United States, owned and operated by Entergy Louisiana. The facility is part of the regional transmission and distribution network, handling voltage levels of 69 kV and 13.8 kV, which are typical for sub-transmission and distribution substations in the area. As a substation within the Entergy Louisiana system, it operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) for interstate transmission and the Louisiana Public Service Commission for intrastate matters. The facility adheres to North American Electric Reliability Corporation (NERC) reliability standards, ensuring grid stability and compliance with mandatory cybersecurity and physical security protocols. The substation plays a critical role in distributing electricity to local communities and industrial customers in the Baton Rouge metropolitan area. Its location near the Mississippi River places it within a region with significant industrial activity, including petrochemical and manufacturing facilities, which depend on reliable power supply for continuous operations.
Environmental context
The substation is situated in a humid subtropical climate zone, with frequent thunderstorms and occasional hurricanes posing risks to electrical infrastructure. The facility's design likely includes flood mitigation measures and storm hardening, given the region's vulnerability to extreme weather events. Its proximity to the Mississippi River and wetlands also necessitates careful management of potential oil spills from transformers to protect local ecosystems.
