Harrison South Substation is an operational electrical substation located in Harrison, Arkansas, United States. Owned and operated by Arkansas Electric Cooperative Corporation, it plays a key role in the regional transmission and distribution network. The substation handles voltage levels of 161 kV and 69 kV, indicating its function as a medium-to-high voltage facility that steps down power for local distribution. As part of the U.S. electrical infrastructure, this substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and security. The facility's voltage levels suggest it is a critical node for connecting bulk transmission to sub-transmission or distribution networks, typical for substations serving rural and suburban areas in Arkansas. The substation's location in Harrison, a city in Boone County, supports the electrical needs of the surrounding community and local industries. Its operational status and integration into the Arkansas Electric Cooperative Corporation's network highlight its importance in maintaining stable power supply to member cooperatives and end-users. The facility contributes to grid resilience and energy access in the region.
Environmental context
The substation is situated in the Ozark Mountains region, characterized by forested hills and a temperate climate. Its operation involves electromagnetic fields and potential oil leakage from transformers, which are managed through standard environmental safeguards. The facility's location in a semi-rural area reduces immediate ecological impact compared to urban settings, but proximity to natural habitats requires adherence to environmental regulations to minimize disturbance.
