Estelline Substation is an electrical substation located in Texas, United States, and is operated by Southwestern Electric Power Company (SWEPCO), a subsidiary of American Electric Power. The facility is operational and functions as a node in the regional transmission and distribution network, stepping down voltage for local distribution. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level infrastructure in the United States. As part of SWEPCO's network, it is subject to regulatory oversight by the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards to ensure grid stability and security. The facility plays a role in delivering electricity to the surrounding rural area in western Texas. Its location near Estelline supports local agricultural and residential loads, contributing to the reliability of the regional power supply. Ongoing maintenance is typical for such assets.
Environmental context
The substation is located in a rural area of Texas, characterized by semi-arid climate and agricultural land use. Electrical infrastructure in such settings typically has minimal direct environmental impact, though considerations include electromagnetic fields and potential effects on local wildlife. The facility's 69 kV voltage level indicates it is part of the distribution network, which generally has lower environmental footprint compared to high-voltage transmission lines.
