Cienega Substation - Operational Electrical Substation in the United States

Cienega Substation is an operational electrical substation located in the United States, with coordinates 32.035111, -110.721900. The facility operates at voltage levels of 138 kV and 13.8 kV, indicating it serves both transmission and distribution functions. As a substation, it is a critical node in the electrical grid, facilitating voltage transformation and power routing. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for bulk power system reliability and FERC oversight for interstate transmission. The voltage levels suggest it connects high-voltage transmission lines (138 kV) to lower-voltage distribution networks (13.8 kV), typical for substations serving urban or industrial areas. The facility's location in Arizona places it within the Western Interconnection, where grid management is coordinated by the Western Electricity Coordinating Council (WECC). Cienega Substation contributes to the reliability of the local power supply by enabling efficient electricity transfer and voltage regulation. Its operational status ensures continued support for residential, commercial, and industrial customers in the region. The substation's role in the grid underscores its importance for maintaining system stability and meeting energy demand.

The substation is located in a semi-arid region of Arizona, where high temperatures and low humidity can affect equipment performance and maintenance schedules. The facility's design likely incorporates measures to mitigate dust and heat impacts, such as insulated switchgear and cooling systems. Its location away from densely populated areas reduces noise and visual impacts, while the surrounding environment supports typical desert flora and fauna.
