Grangeville Substation - 69 kV Electrical Substation in Louisiana, USA

Grangeville Substation is an operational electrical substation located in Louisiana, United States, and operated by DEMCO. The facility operates at a voltage level of 69 kV, classifying it as a medium-voltage substation typical of distribution-level infrastructure in rural and suburban areas. As a substation owned and operated by DEMCO, an electric cooperative serving parts of Louisiana, Grangeville Substation is subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and regulated by the Federal Energy Regulatory Commission (FERC) for its interconnection to the bulk power system. The substation likely employs standard switchgear and protection systems compliant with IEEE and IEC standards to ensure safe and reliable power delivery. The substation plays a critical role in maintaining grid stability for the surrounding community, supporting local residential, commercial, and agricultural loads. Its location in rural Louisiana underscores its importance in extending reliable electricity access to areas that may be distant from major transmission corridors.

The substation is situated in a rural area of Louisiana, characterized by low population density and proximity to natural landscapes. The 69 kV voltage level indicates a medium-scale facility that typically has a limited environmental footprint, with minimal visual impact and no direct emissions. However, the surrounding ecosystem may include wetlands and forests, requiring careful management of vegetation and stormwater runoff to prevent soil erosion and protect local water quality.
