Overview
Dale Substation is an operational electrical substation in Arizona, United States, owned and operated by Arizona Public Service. It operates at a voltage of 69 kV, serving the local grid.
Dale Substation is an operational electrical substation located in Arizona, United States. Owned and operated by Arizona Public Service, the facility plays a role in the regional electrical infrastructure, stepping down transmission voltages for distribution to local consumers. The substation operates at 69 kV, a common sub-transmission voltage level in the United States. As part of the Arizona Public Service network, Dale Substation is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations for transmission-level assets. The facility likely employs standard substation automation protocols such as IEC 61850 to ensure efficient monitoring and control. The 69 kV voltage level indicates it serves as a distribution substation, connecting the high-voltage transmission system to lower-voltage distribution lines. The substation's location in Arizona places it within a region experiencing growing electricity demand due to population growth and economic development. Its operational status ensures continued reliability for the surrounding community. The facility contributes to grid stability by providing voltage regulation and fault isolation, supporting the overall resilience of the electrical infrastructure in the area.
Environmental context
The substation is located in a semi-arid region of Arizona, where high summer temperatures and low humidity can affect equipment performance and increase cooling demands. The facility's design likely incorporates measures to mitigate heat-related stress on transformers and switchgear. Its urban or suburban setting may require careful management of electromagnetic fields and noise to minimize impact on nearby residents. The substation's role in distributing power supports local energy needs while adhering to environmental regulations.
