Mukwonago Substation - 138 kV Electrical Infrastructure in Wisconsin, United States

Mukwonago is an operational electrical substation located in Wisconsin, United States. Operating at a voltage of 138 kV, it is classified as a transmission-level substation, supporting the regional power grid. The facility is part of the broader North American electrical infrastructure, which is regulated by NERC reliability standards and FERC oversight. As a 138 kV substation, Mukwonago serves as a critical node for stepping down high-voltage electricity from transmission lines to sub-transmission or distribution levels. Substations of this voltage class are common in the United States and are essential for maintaining grid stability and reliability. The facility likely includes switchgear, transformers, and protection systems compliant with industry standards such as IEEE C37. Environmentally, the substation's operation is designed to minimize local impact, with proper grounding and shielding to manage electromagnetic fields. Its location in Wisconsin, a state with a mix of urban and rural areas, means it supports both residential and industrial electricity needs. The facility contributes to the resilience of the regional grid, particularly during peak demand periods.

The substation is situated in Wisconsin, a region with cold winters and moderate summers, which influences electricity demand patterns. As a 138 kV facility, it is part of the transmission network that connects power generation sources to load centers. The site is likely designed with environmental considerations such as stormwater management and wildlife protection, common for substations in the United States.
