Overview
LeTourneau Substation is an operational electrical substation in the United States, owned and operated by Southwestern Electric Power Company. It operates at a voltage of 69 kV, serving the regional grid.
LeTourneau Substation is an operational electrical substation located in the United States, owned and operated by Southwestern Electric Power Company (SWEPCO), a subsidiary of American Electric Power. The facility plays a role in the regional transmission and distribution network, stepping down voltage for local distribution or interconnecting transmission lines. The substation operates at a voltage of 69 kV, which is a common sub-transmission voltage level in the United States. As part of SWEPCO's infrastructure, it is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations for transmission-level assets. The facility likely includes switchgear, transformers, and protection systems compliant with standards such as IEEE C37 for high-voltage equipment. Located in an area with coordinates 32.458616, -94.731780, the substation supports grid stability and electricity delivery to surrounding communities. Its operational status ensures continued service within the broader electrical infrastructure of the region, contributing to the reliability of the power supply for residential, commercial, and industrial customers.
Environmental context
The substation is situated in a region with a humid subtropical climate, which can influence equipment maintenance and vegetation management around the facility. The 69 kV voltage level indicates it is part of the sub-transmission network, typically located in less densely populated areas, reducing direct environmental impact compared to higher voltage lines. Standard environmental practices for substations include oil containment for transformers and noise mitigation measures.
