Overview
Harrison North is an operational electrical substation in Wisconsin, USA, handling 138 kV and 69 kV voltage levels. It plays a key role in regional grid stability.
Harrison North is an operational electrical substation located in Wisconsin, United States, with coordinates 44.365132, -89.091254. The facility operates at voltage levels of 138 kV and 69 kV, indicating its role in both transmission and sub-transmission within the regional power grid. As a substation in the United States, Harrison North operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure grid reliability and compliance with mandatory reliability standards. The facility's voltage levels suggest it is a medium-to-large scale substation, typical for serving urban or industrial loads in the Midwest. The substation's location in Wisconsin places it within the Midcontinent Independent System Operator (MISO) footprint, which manages the regional transmission grid. Its operational status contributes to the stability and resilience of the local electrical infrastructure, supporting residential, commercial, and industrial customers in the area.
Environmental context
The substation is situated in a rural area of Wisconsin, surrounded by agricultural land and small water bodies. Its operation involves electromagnetic fields and potential oil leakage from transformers, which are managed under environmental regulations. The site's distance from sensitive ecosystems reduces direct ecological impact, but routine maintenance and emergency response plans are essential to prevent soil or water contamination.
