Overview
McDade Substation is an operational electrical substation in the United States, owned and operated by Southwestern Electric Power Company. It operates at a voltage of 138 kV, serving the regional power grid.
McDade Substation is an operational electrical substation located in the United States, owned and operated by Southwestern Electric Power Company (SWEPCO). The facility is situated at coordinates 32.366076, -93.501049, likely serving the surrounding area in Louisiana or Texas. As a 138 kV substation, it falls within the sub-transmission voltage class, playing a key role in distributing power from high-voltage transmission lines to local distribution networks. 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 bulk power system. SWEPCO, a subsidiary of American Electric Power, is a regulated utility serving customers in Arkansas, Louisiana, and Texas. The 138 kV voltage level is common for regional power distribution, connecting larger transmission systems to industrial and residential areas. McDade Substation contributes to the stability and reliability of the regional electrical grid. Its operational status ensures continued power delivery to communities and industries in the area. The facility's location and voltage level indicate it serves as a critical node in the local power infrastructure, supporting economic activity and daily life.
Environmental context
The substation's location in the southern United States places it in a region with a warm climate and potential for severe weather events such as hurricanes and thunderstorms, which can impact grid reliability. The facility's design likely includes measures to withstand such conditions, including robust grounding and surge protection. As an electrical substation, its environmental footprint is primarily related to land use and electromagnetic fields, with minimal direct emissions.
