Decatur Substation - Operational Electrical Substation in the United States

Decatur substation is an operational electrical substation located in the United States, with coordinates 36.113994, -115.213440. It operates at multiple voltage levels including 230 kV, 138 kV, and 69 kV, indicating its role in both transmission and distribution networks. The facility is part of the broader North American power grid, which is regulated by NERC reliability standards and FERC oversight for interstate electricity transmission. The substation's voltage levels suggest it serves as a critical node for stepping down high-voltage transmission power to lower voltages for local distribution. In the United States, substations like Decatur are essential for maintaining grid reliability and are subject to NERC's Critical Infrastructure Protection (CIP) standards. The facility likely includes modern switchgear and automation systems compliant with IEC 61850 standards for substation communication. Located in an urban area near Las Vegas, Nevada, Decatur substation supports the electrical infrastructure for a densely populated region with high energy demand. Its operational status ensures continued service to residential, commercial, and industrial customers. The substation contributes to grid resilience by enabling voltage regulation and fault isolation, which are vital for preventing widespread outages.

The substation is situated in an arid urban environment, typical of the Mojave Desert region. Its operation involves managing high-voltage electricity, which can generate electromagnetic fields and require careful siting to minimize visual and noise impacts. The facility's age and technology level influence its environmental footprint, with modern substations incorporating SF6-free insulation and noise-reducing designs. The local grid's reliance on this substation underscores its importance for integrating renewable energy sources like solar power, which is abundant in the area.
