Overview
Belfair Substation is an operational electrical substation in Louisiana, United States, owned by Entergy Louisiana. It operates at voltage levels of 69 kV and 13.8 kV, serving the regional grid.
Belfair Substation is an operational electrical substation located in Louisiana, United States. Owned by Entergy Louisiana, the facility plays a key role in the regional electrical infrastructure, stepping down transmission voltages for local distribution. As a substation, it is part of the larger grid managed under North American reliability standards. The substation operates at two voltage levels: 69 kV for transmission and 13.8 kV for distribution, indicating its function as a step-down substation. This configuration is typical for facilities that connect high-voltage transmission lines to lower-voltage distribution networks serving industrial, commercial, and residential customers. Entergy Louisiana, the owner and operator, is a regulated utility subject to FERC and NERC compliance requirements. Located in Louisiana, the substation supports the state's energy needs, which include a mix of industrial, petrochemical, and residential loads. The facility's operational status ensures continued grid stability and power delivery in the region. Its role in voltage transformation is critical for maintaining reliable electricity supply to surrounding communities.
Environmental context
The substation is situated in Louisiana, a state with a humid subtropical climate and frequent thunderstorms, which can impact grid reliability. The facility's location in an urbanizing area near Baton Rouge means it supports growing electricity demand while operating under environmental regulations that manage stormwater runoff and equipment insulation to prevent leaks. The use of SF6 gas in switchgear is a common environmental consideration for substations, though specific practices at this site are not detailed.
