Overview
Orebank Substation is an operational electrical substation in the United States, owned and operated by APS. It operates at a voltage of 138 kV, serving the regional grid.
Orebank Substation is an electrical substation located in the United States, owned and operated by Arizona Public Service (APS). The facility is operational and plays a role in the transmission and distribution of electricity within the regional power grid. With a voltage level of 138 kV, it is classified as a high-voltage substation, typical for sub-transmission or distribution applications. The substation operates under the regulatory framework of the United States, which includes reliability standards set by the North American Electric Reliability Corporation (NERC) and oversight by the Federal Energy Regulatory Commission (FERC) for transmission-level assets. As a 138 kV facility, it is likely integrated into the bulk power system, subject to compliance with NERC's Critical Infrastructure Protection (CIP) standards. The equipment likely includes circuit breakers, transformers, and switchgear conforming to industry standards such as IEEE and ANSI. Environmentally, the substation's location in the United States means it must adhere to environmental regulations regarding electromagnetic fields, oil containment, and noise. Its role in the grid supports reliable electricity delivery to residential, commercial, and industrial customers. The facility's operational status ensures continued contribution to grid stability and energy distribution in the region.
Environmental context
The substation is located in a region that may experience seasonal weather variations, including thunderstorms and heatwaves, which can impact grid reliability. As a 138 kV facility, it is subject to environmental regulations concerning electromagnetic field exposure and oil spill containment from transformers. Its operation supports the integration of renewable energy sources and helps maintain voltage stability in the local distribution network.
