Hope NW 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 transmission network. The substation operates at a voltage of 115 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the Entergy Arkansas system, the substation is subject to regulatory oversight by the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure grid stability and security, including requirements for maintenance, cybersecurity, and operational coordination. The 115 kV voltage level places this facility in the medium-voltage range, supporting local distribution and industrial loads. The substation's location in rural Arkansas contributes to the reliability of electricity supply in the region. It serves as a critical node for power distribution, connecting transmission lines to local feeders. The operational status and adherence to NERC standards help maintain consistent power delivery to residential, commercial, and agricultural customers in the area.
Environmental context
The substation is situated in a rural area of Arkansas, where the surrounding landscape includes agricultural fields and forests. Electrical infrastructure at this voltage level typically has a localized environmental footprint, limited to the substation footprint and access roads. The facility's operation supports grid stability without significant direct environmental impact, though it contributes to the broader energy system's efficiency.
