Overview
Colbyville Substation is an operational electrical substation owned by Minnesota Power in the United States. It operates at 115 kV, supporting regional grid stability.
Colbyville Substation is an operational electrical substation located in the United States, owned and operated by Minnesota Power. The facility operates at a voltage level of 115 kV, classifying it as a medium-voltage substation that plays a key role in local power distribution and transmission. As part of Minnesota Power's infrastructure, the substation is subject to North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) regulations for transmission assets. The 115 kV voltage level is typical for sub-transmission or distribution substations, connecting bulk power systems to local networks. The substation's location near Duluth, Minnesota, places it in a region with cold winters and significant industrial activity, including mining and paper production. Its role in the grid ensures reliable electricity supply to residential, commercial, and industrial customers, contributing to the overall stability of the regional power system.
Environmental context
The substation is situated in a temperate climate zone with seasonal temperature extremes, which can affect equipment performance and maintenance schedules. Its urban-rural interface location means it serves both densely populated areas and surrounding natural landscapes, requiring careful management of electromagnetic fields and visual impact. The facility's operation aligns with standard environmental practices for electrical infrastructure, including oil containment for transformers and noise mitigation.
