Overview
Green Forest Substation is an operational electrical substation in Arkansas, United States, owned by Entergy Arkansas. It operates at 161 kV and 13.86 kV voltage levels.
Green Forest Substation is an operational electrical substation located in Arkansas, United States. Owned by Entergy Arkansas, the facility serves as a key node in the regional power grid, stepping down transmission voltage for local distribution. The substation operates at two voltage levels: 161 kV for transmission and 13.86 kV for distribution, indicating its role in connecting high-voltage transmission lines to lower-voltage distribution networks. As part of the Entergy Arkansas system, it falls under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. The facility's design likely incorporates IEC 61850 standards for substation automation, common in modern US substations. Located in a rural area of Carroll County, the substation supports the electrical infrastructure of the surrounding community. Its operational status ensures reliable power delivery to residential, commercial, and industrial customers in the region. The facility's grid role is critical for maintaining voltage stability and load balancing within the Entergy Arkansas service territory.
Environmental context
The substation is situated in a rural area of the Ozark Mountains region, characterized by forested hills and scattered development. Its operation involves electromagnetic fields and potential oil leakage from transformers, though modern containment measures mitigate environmental risks. The site's location away from sensitive habitats reduces direct ecological impact, but the substation supports the broader grid that powers local communities and industries.
