Roxie Substation: Mississippi Electrical Substation Operated by Entergy Mississippi

Roxie Substation is an operational electrical substation located in Mississippi, United States, operated by Entergy Mississippi. The facility handles primary voltage levels of 115 kV and secondary distribution at 14.4 kV, placing it in the medium-voltage range typical for regional transmission and distribution substations. Operating under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), Roxie Substation adheres to mandatory reliability standards for grid stability. The substation likely employs conventional switchgear and transformer technology, with automation potentially aligned with IEC 61850 standards for substation communication. As part of Entergy Mississippi's network, Roxie Substation plays a role in delivering electricity to local communities and industries. Its location in a rural area of Mississippi contributes to the resilience of the regional power grid, supporting both residential and commercial loads.

The substation is situated in a rural area of Mississippi, where the surrounding environment includes agricultural land and forested regions. The presence of high-voltage equipment requires careful management of electromagnetic fields and potential impacts on local wildlife. Standard mitigation measures such as vegetation management and oil containment for transformers are typically employed to minimize environmental risks.
