Overview
Humbolt Terminal is an operational electrical substation in the United States, operating at 138 kV. It plays a role in regional grid stability and power distribution.
Humbolt Terminal is an operational electrical substation located in the United States, with coordinates 43.093870, -87.903541. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation critical for transmission and distribution within the regional grid. As part of the U.S. electrical infrastructure, it adheres to NERC reliability standards and FERC regulations for transmission-level assets. The substation's 138 kV voltage level indicates its role in stepping down power from higher transmission voltages for local distribution or interconnecting generation sources. In the U.S., substations of this scale are typically equipped with modern switchgear and automation systems compliant with ISO/IEC 61850 standards to ensure efficient and reliable operation. The facility's operational status confirms its active contribution to the grid. Environmentally, the substation's location near Milwaukee, Wisconsin, places it in an urban-industrial context, where it supports local electricity demand and grid resilience. Its operation involves managing electromagnetic fields and insulating gases, with standard environmental safeguards. The facility's significance lies in its contribution to maintaining voltage stability and power quality for the surrounding community and industrial users.
Environmental context
The substation is located in an urban area near Milwaukee, Wisconsin, where it supports dense residential and industrial electricity demand. Its 138 kV voltage level requires careful management of electromagnetic fields and potential use of sulfur hexafluoride (SF6) insulation, which has a high global warming potential. Standard environmental practices include leak detection and regular maintenance to minimize ecological impact.
