Sauk Trail Substation - Operational 138 kV Electrical Infrastructure in the United States

Sauk Trail is an operational electrical substation located in the United States, with coordinates 43.732822, -87.731545. The facility operates at a voltage of 138 kV, which is typical for sub-transmission or distribution-level infrastructure, serving to step down power for local distribution networks. Operating within the United States, this substation is subject to NERC reliability standards and FERC regulation for grid stability. The 138 kV voltage class is common for regional power transfer, and the facility likely includes switchgear and transformers to manage power flow. Its location in the Great Lakes region suggests it may serve industrial or urban load centers. The substation's operational status indicates it is actively contributing to the electrical grid. As part of the broader transmission network, it supports reliable electricity delivery to surrounding communities and industries, aligning with sector standards for safety and efficiency.

The substation is situated in a region with a temperate climate, where seasonal weather variations can impact grid operations. Its 138 kV voltage level places it in a medium-voltage category, typically found in suburban or rural settings. The facility's design likely incorporates standard environmental safeguards to mitigate any local ecological impact, such as oil containment for transformers and noise reduction measures.
