Trumann Substation - Operational Substation by Entergy Arkansas in the United States

Trumann Substation is an operational electrical substation located in the United States, operated by Entergy Arkansas. The facility handles primary voltage levels of 161 kV and 13.86 kV, indicating its role in both transmission and distribution within the regional power grid. As part of the U.S. electrical infrastructure, Trumann Substation operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) and adheres to North American Electric Reliability Corporation (NERC) reliability standards. The substation's voltage levels suggest it serves as a critical node for stepping down power from high-voltage transmission lines to lower-voltage distribution networks, typical of substations in rural and suburban areas. The substation plays a key role in delivering reliable electricity to the surrounding community, supporting residential, commercial, and industrial loads. Its operation by Entergy Arkansas, a major utility in the region, underscores its importance in maintaining grid resilience and meeting local energy demands.

The substation is located in a rural area near Trumann, Arkansas, where the surrounding landscape includes agricultural fields and scattered residential developments. The facility's design and operation consider local environmental factors such as stormwater management and wildlife protection, typical for substations in this region. Its voltage levels and equipment age influence its environmental footprint, with modern switchgear reducing potential oil leaks and SF6 emissions.
