Armstrong Substation - Operational 115 kV Substation in the United States

Armstrong Substation is an operational electrical substation located in the United States, specifically at coordinates 44.769587, -94.161745. Operated by Light & Power Commission, this facility plays a key role in the regional electrical infrastructure, stepping down transmission voltages for local distribution. The substation operates at a voltage of 115 kV, which is typical for sub-transmission or primary distribution in the US grid. As part of the North American power system, it adheres to NERC reliability standards and FERC regulations, ensuring grid stability and compliance with mandatory reliability requirements. The facility's design likely incorporates standard substation automation protocols such as IEC 61850 for efficient monitoring and control. Located in a rural or semi-rural area of the United States, Armstrong Substation supports local communities and industries by providing reliable electrical supply. Its operational status ensures continued service, contributing to the resilience of the regional grid. The substation's role is critical for maintaining voltage levels and power quality for end-users.

The substation is situated in a region with a continental climate, characterized by cold winters and warm summers. Its rural location minimizes direct environmental impact on densely populated areas, but the infrastructure must withstand seasonal weather extremes. The 115 kV voltage level indicates moderate scale, with typical environmental considerations including electromagnetic field management and vegetation clearance for line safety.
