Overview
Rangley Substation is an operational electrical substation in Colorado, United States, operating at 138 kV. It plays a role in regional grid stability and power distribution.
Rangley Substation is an operational electrical substation located in Colorado, United States. The facility operates at a voltage of 138 kV, classifying it as a medium-voltage substation typical for regional power distribution and transmission support. As part of the U.S. electrical grid, it contributes to the reliability of electricity supply in the area. 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 bulk power systems. The 138 kV voltage level is common for sub-transmission networks that connect distribution systems to higher-voltage transmission lines, ensuring efficient power flow and grid stability. Located in a rural area of Colorado, Rangley Substation supports local communities and industries by providing reliable electrical infrastructure. Its operational status ensures continued service to the region, and its integration into the wider grid helps maintain system resilience against disturbances. The facility's role is critical for meeting the energy demands of the surrounding area.
Environmental context
The substation is situated in a rural region of Colorado, characterized by semi-arid climate and sparse vegetation. Electrical infrastructure in such areas typically has lower environmental impact compared to urban settings, though it may affect local wildlife and land use. The 138 kV voltage level indicates moderate electromagnetic field exposure, which is managed through standard siting and safety practices. The facility's operation aligns with NERC and FERC regulations that include environmental considerations for grid reliability.
Frequently asked questions
Rangley Substation is located in Colorado, United States, near the town of Rangley. Its coordinates are approximately 40.0745° N, -108.8215° W.
