Overview
Lepanto Substation is an operational electrical substation in Arkansas, United States, owned and operated by Entergy Arkansas. It handles voltages of 161 kV and 13.86 kV, serving the local grid.
Lepanto Substation is an electrical substation located in Arkansas, United States, and is owned and operated by Entergy Arkansas. The facility is operational and plays a role in the regional power transmission and distribution network. As a substation, it steps down high-voltage electricity for local distribution, with voltage levels of 161 kV and 13.86 kV. The substation operates under the regulatory framework of the United States, which includes reliability standards set by the North American Electric Reliability Corporation (NERC) and oversight by the Federal Energy Regulatory Commission (FERC) for transmission-level assets. Entergy Arkansas, as a utility, must comply with these standards to ensure grid stability and reliability. The facility's voltage levels indicate it serves both transmission (161 kV) and distribution (13.86 kV) functions, typical for a substation in a rural or suburban setting. Lepanto Substation contributes to the electrical infrastructure of the region, supporting residential, commercial, and industrial customers. Its location in Arkansas places it within the Entergy system, which serves parts of several southern states. The substation's operational status ensures continued power delivery and grid resilience in the area.
Environmental context
The substation is situated in a rural area of Arkansas, where the local environment includes agricultural land and small communities. Electrical infrastructure like Lepanto Substation is designed to minimize environmental impact through proper siting and maintenance. The voltage levels and equipment age can influence electromagnetic field exposure and land use, but modern substations are built with environmental considerations in mind.
