Overview
Winona Substation is an operational electrical substation in Mississippi, United States, operated by Entergy Mississippi. It handles voltages of 115 kV and 13.86 kV, serving the local grid.
Winona Substation is an operational electrical substation located in Mississippi, United States. Owned and operated by Entergy Mississippi, it plays a key role in the regional power distribution network. The substation handles primary voltage levels of 115 kV and 13.86 kV, indicating its function in stepping down transmission-level power for local distribution. As part of the U.S. electrical infrastructure, Winona Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security. The substation's voltage levels suggest it is a medium-scale facility typical of rural or suburban distribution networks in the region. The substation's location in Mississippi places it within a region prone to severe weather, including hurricanes and thunderstorms, which can impact grid stability. Its role in the Entergy Mississippi network is critical for maintaining reliable power supply to surrounding communities. The facility's operational status and integration into the broader grid underscore its importance for local energy resilience.
Environmental context
The substation is situated in a region of Mississippi characterized by mixed agricultural and forested land, with a humid subtropical climate. The local environment is subject to seasonal storms and heat, which can stress electrical infrastructure. The substation's voltage levels and rural location suggest it serves a dispersed population, with potential environmental considerations related to land use and stormwater management around the facility.
