Armand Substation - 138 kV Operational Substation in the United States

Armand Substation is an operational electrical substation located in the United States, with coordinates 29.624029, -95.088067. Operating at a voltage of 138 kV, it is classified as a high-voltage substation, typically serving transmission-level functions within the electrical grid. The facility is part of the broader North American power system, which is regulated under NERC reliability standards and FERC oversight. The substation operates under the regulatory framework of the United States, where transmission assets are subject to NERC's Critical Infrastructure Protection (CIP) standards and FERC's jurisdiction over interstate electricity markets. At 138 kV, Armand Substation falls within the typical range for sub-transmission or transmission substations, supporting the distribution of electricity from generation sources to load centers. The facility's operational status indicates it is actively contributing to grid reliability. Located in the Gulf Coast region of Texas, the substation serves an area with significant industrial and urban demand, including petrochemical complexes and residential communities. Its role in the electrical infrastructure is critical for maintaining voltage stability and ensuring reliable power supply to downstream customers. The facility's integration into the regional grid underscores its importance for local economic activity and energy security.

The substation is situated in a coastal plain environment near the Gulf of Mexico, where humidity and salt spray can affect equipment longevity. The region experiences occasional tropical storms and hurricanes, necessitating robust infrastructure design to withstand extreme weather. The facility's operation supports the electrical needs of nearby industrial and residential areas, contributing to the local economy while requiring careful management of potential environmental impacts such as electromagnetic fields and stormwater runoff.
