Dedeaux Road Substation - Mississippi Electrical Substation Operated by Coast Electric Power Association

Dedeaux Road Substation is an electrical substation located in Mississippi, United States, owned and operated by Coast Electric Power Association. The facility is operational and plays a role in the regional power distribution network, stepping down transmission voltages for local use. The substation operates at voltage levels of 115,000 volts (115 kV) and 23,000 volts (23 kV), indicating it serves as a distribution substation that connects high-voltage transmission lines to lower-voltage distribution networks. As part of the U.S. electrical infrastructure, it adheres to NERC reliability standards and FERC regulations, ensuring grid stability and safety. Located in a coastal area of Mississippi, the substation supports the electrical needs of the surrounding community. Its operation is critical for maintaining reliable power supply, especially given the region's vulnerability to extreme weather events. The facility contributes to the resilience of the local grid by providing voltage regulation and load management.

The substation is situated in a coastal region of Mississippi, an area prone to hurricanes and severe storms. Electrical infrastructure in such locations must be designed to withstand high winds and flooding. The facility's role in voltage regulation helps maintain grid stability during weather events, reducing the risk of outages. Its location near residential and commercial areas necessitates careful management of electromagnetic fields and noise, though standard mitigation measures are typically in place.
