D'Iberville Northwest Substation is an electrical substation located in D'Iberville, Mississippi, United States. Owned and operated by Mississippi Power, the facility is part of the regional transmission and distribution network, handling voltages of 230 kV, 115 kV, and 13.2 kV. This substation plays a key role in stepping down high-voltage electricity for local distribution. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the U.S. bulk power system. As a transmission-level asset, it is subject to NERC's Critical Infrastructure Protection (CIP) standards. The facility's voltage levels indicate it serves both transmission (230 kV) and sub-transmission/distribution (115 kV, 13.2 kV) functions, typical for substations in the region. Located in the Gulf Coast region, the substation supports the electrical infrastructure for D'Iberville and surrounding areas. Its operational status ensures grid stability for residential, commercial, and industrial customers. The facility's design and maintenance align with industry standards for reliability and safety, contributing to the resilience of the local power system.
Environmental context
The substation is situated in a coastal area of Mississippi, which is prone to hurricanes and severe weather events. This environmental context requires robust infrastructure design to withstand high winds and flooding, ensuring continuous power supply. The facility's location near urban development also necessitates careful management of electromagnetic fields and noise to minimize community impact.
