Harrison East Substation is an operational electrical substation located in Arkansas, United States. Owned and operated by Entergy Arkansas, the facility plays a key role in the regional power distribution network. The substation handles primary voltage levels of 161 kV and secondary voltage of 13.86 kV, indicating its function in stepping down transmission-level power for local distribution. As part of the U.S. electrical infrastructure, Harrison East Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for the bulk power system, ensuring stable and secure grid operations. The substation's voltage levels suggest it is a medium-scale facility, typical for serving urban or suburban areas in Arkansas. The substation's location in Arkansas places it within the Entergy Arkansas service territory, which covers much of the state. Its operational status and integration into the wider grid contribute to the reliability of electricity supply for residential, commercial, and industrial customers in the region. The facility's role in voltage transformation is critical for maintaining grid stability and meeting local demand.
Environmental context
The substation is situated in a region with a humid subtropical climate, which can influence electrical infrastructure through seasonal temperature extremes and storm events.
