I-94 Substation - Operational 115 kV Substation in the United States

I-94 Substation is an operational electrical substation located in the United States, with coordinates near 45.47°N, 94.12°W. The facility operates at a voltage of 115 kV, classifying it as a medium-voltage substation typical for regional power distribution and transmission support. Operating within the United States, this substation falls under the regulatory oversight of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC) for reliability standards and interstate electricity regulation. The 115 kV voltage level is common for sub-transmission systems that connect distribution networks to higher-voltage transmission lines. The substation's location near Interstate 94 suggests it serves a corridor with mixed urban and rural loads, supporting grid stability for surrounding communities. Its operational status indicates ongoing contribution to the electrical infrastructure, facilitating power flow and voltage regulation in the region.

The substation is situated in a region with a continental climate, experiencing cold winters and warm summers. Its location near a major highway implies potential impacts from road salt and runoff, though standard substation design includes drainage and containment measures. The 115 kV voltage level indicates moderate electromagnetic fields, which are managed through siting and shielding practices.
