Overview
Fairgrounds Substation is an operational electrical substation in the United States, owned by United Power and Tri-State Generation and Transmission Association. It operates at 115 kV, serving as a key node in the regional transmission grid.
Fairgrounds Substation is an operational electrical substation located in the United States, with coordinates 39.943661, -104.885124. The facility is jointly owned by United Power and Tri-State Generation and Transmission Association, two major utility cooperatives in the region. As a 115 kV substation, it falls within the medium-voltage range typical for distribution and sub-transmission networks, playing a critical role in stepping down power from high-voltage transmission lines for local distribution. 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. In the United States, substations like Fairgrounds are subject to NERC's Critical Infrastructure Protection (CIP) standards, ensuring cybersecurity and physical security. The 115 kV voltage level is common for regional interconnections, and the facility likely includes switchgear, transformers, and protection systems compliant with IEEE and IEC standards. Fairgrounds Substation contributes to grid stability and reliability in its service area, supporting the growing demand for electricity in the region. Its location near Denver, Colorado, places it within a rapidly urbanizing area, where substations are essential for integrating renewable energy sources and maintaining power quality. The facility's operational status ensures continued service to residential, commercial, and industrial customers, underpinning the local economy and community well-being.
Environmental context
The substation is situated in an urbanizing area near Denver, Colorado, where land use is a mix of residential and commercial development. Electrical infrastructure at this voltage level typically has a moderate environmental footprint, with considerations for electromagnetic fields (EMF), noise from transformers, and visual impact. The facility's operation supports grid reliability, which is critical for integrating renewable energy sources like solar and wind, thereby contributing to broader environmental goals. Local regulations may require adherence to setback distances and landscaping to mitigate visual and noise impacts.
