Overview
Park Hill Substation is an operational 138 kV electrical substation in Milwaukee, Wisconsin, owned by American Transmission Company and operated by Wisconsin Electric Power Company.
Park Hill Substation is an operational electrical substation located in Milwaukee, Wisconsin, United States. It operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical for distribution and sub-transmission substations serving urban and industrial areas. The facility is owned by American Transmission Company (ATC) and operated by Wisconsin Electric Power Company, a subsidiary of WEC Energy Group. As a 138 kV substation, Park Hill plays a critical role in the regional grid by stepping down transmission-level power for local distribution. The facility operates under the regulatory oversight of the Federal Energy Regulatory Commission (FERC) for wholesale electricity markets and must comply with North American Electric Reliability Corporation (NERC) reliability standards. The substation likely includes modern switchgear and protection systems to ensure grid stability and safety. The substation serves the Milwaukee metropolitan area, supporting residential, commercial, and industrial loads. Its location in an urban setting underscores its importance for maintaining reliable electricity supply to a densely populated region. The facility's operational status and ownership by ATC, a major transmission utility, indicate a well-maintained asset critical to the regional power infrastructure.
Environmental context
The substation is situated in an urban environment in Milwaukee, Wisconsin, where local environmental considerations include stormwater management and electromagnetic field (EMF) mitigation. The facility's 138 kV voltage level requires adherence to NERC reliability standards to prevent grid disturbances that could impact surrounding communities. The site's proximity to residential areas may involve noise and visual impact mitigation measures.
