Overview
Avra Valley Substation is an operational electrical substation in Arizona, United States, operating at 115 kV. It plays a role in regional grid stability and power distribution.
Avra Valley Substation is an operational electrical substation located in Arizona, United States. The facility operates at a voltage of 115 kV, placing it within the sub-transmission or distribution voltage range typical for regional power distribution networks. As a substation, it serves as a node for voltage transformation and switching, contributing to the reliability of the local electrical grid. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards for bulk power system and FERC oversight for transmission-level assets. The facility's voltage level suggests it may be part of a utility's distribution system, subject to state-level public utility commission regulations. Substations of this scale are commonly found in both urban and rural settings, supporting load centers or industrial areas. Avra Valley Substation's location in Arizona places it in a region with growing energy demand due to population growth and economic development. The substation's role in the grid is critical for maintaining voltage stability and ensuring reliable electricity supply to surrounding communities. Its operational status indicates ongoing contribution to the regional power infrastructure, supporting both residential and commercial customers.
Environmental context
The substation is located in the Sonoran Desert region of Arizona, an area characterized by arid climate and high solar irradiance. Electrical infrastructure in such environments must consider thermal management and equipment durability under extreme temperatures. The facility's voltage level and location suggest it may integrate with renewable energy sources like solar farms, which are prevalent in the region. Proximity to natural habitats requires careful siting to minimize ecological disruption.
