Overview
Butler Substation is an operational electrical substation in the United States, owned and operated by APS. It operates at a voltage of 138 kV, serving as a key node in the regional grid.
Butler Substation is an operational electrical substation located in the United States, owned and operated by Arizona Public Service (APS). The facility operates at a voltage level of 138 kV, which classifies it as a medium-to-high voltage substation typically used for subtransmission and distribution within the power grid. This voltage level is common for connecting local distribution networks to higher-voltage transmission systems, ensuring reliable electricity delivery to surrounding communities. As part of the U.S. electrical infrastructure, Butler Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for bulk power systems, including substation automation and protection schemes. The substation likely incorporates standard technologies such as circuit breakers, transformers, and switchgear to manage power flow and maintain grid stability. The substation plays a critical role in the local grid by stepping down voltage from transmission lines to distribution levels, serving residential, commercial, and industrial customers in the region. Its operational status ensures continuous power supply, contributing to the overall reliability of the electrical network. The facility's location in the United States places it within a highly regulated and technologically advanced electrical infrastructure sector.
Environmental context
The substation is located in a region with a temperate climate, which influences the design and maintenance of electrical equipment. Seasonal temperature variations and potential weather events such as thunderstorms or snow require robust insulation and protection systems. The facility's urban or rural setting affects its environmental footprint, with considerations for electromagnetic fields, noise, and visual impact. Proper grounding and oil containment measures are typically in place to mitigate risks to soil and water.
