Bonner Substation - 161 kV Electrical Substation in the United States

Bonner Substation is an operational electrical substation located in the United States, with coordinates 46.875128, -113.872856. The facility operates at a voltage of 161 kV, placing it in the high-voltage transmission category, which is critical for long-distance power transfer and grid interconnection. As a substation in the United States, Bonner Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards and ensure the stability of the bulk power system. The 161 kV voltage level is typical for sub-transmission or transmission applications, often serving as a link between higher voltage transmission lines and lower voltage distribution networks. The substation's location in a rural area of Montana suggests it may serve local communities or industrial loads, contributing to the reliability of the regional grid. Its operational status indicates ongoing maintenance and compliance with NERC standards, which are essential for preventing outages and ensuring safe operation.

The substation is situated in a rural area near Missoula, Montana, characterized by forested terrain and proximity to the Clark Fork River. Electrical infrastructure in such settings must consider wildfire risk, vegetation management, and wildlife protection. The 161 kV voltage level requires clearance and insulation to prevent flashovers, especially in areas with seasonal snow and ice. Proper grounding and shielding are also important to mitigate lightning strikes common in the region.
