Overview
Cox Substation is an operational 345 kV electrical substation located in the United States. It plays a key role in high-voltage transmission grid stability.
Cox Substation is an operational electrical substation located in the United States, with a voltage level of 345 kV, placing it in the high-voltage transmission category. This facility is part of the nation's bulk power system, which is critical for long-distance electricity transfer and grid reliability. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for transmission-level assets. The 345 kV voltage class is typical for major transmission interconnections, often linking generation sources to load centers. As a high-voltage substation, Cox Substation contributes to grid stability and energy delivery across a wide region. Its location in the southwestern United States supports the integration of diverse energy sources and helps maintain reliable electricity supply for communities and industries.
Environmental context
The substation is situated in a semi-arid region of the southwestern United States, where high-voltage transmission infrastructure is essential for connecting remote renewable energy resources to urban centers. The facility's operation supports grid stability in an area prone to extreme weather events, such as heatwaves and dust storms, which can impact electrical infrastructure.
Frequently asked questions
Cox Substation is located in the United States, with coordinates approximately 32.3320° N, -106.7103° W.
Cox Substation operates at 345 kV, which is a high-voltage level used for long-distance transmission in the US power grid.
Cox Substation is subject to NERC reliability standards and FERC regulation, which govern the operation and maintenance of transmission-level electrical infrastructure in the United States.
A 345 kV substation steps down high-voltage electricity from transmission lines to lower voltages for distribution, or interconnects multiple transmission lines to enhance grid reliability and power flow management.
Substations in the southwestern US must be designed to withstand high temperatures, dust, and occasional extreme weather. They also support integration of solar and wind energy, which are abundant in the region.
