Overview
Hillman Substation is an operational electrical substation in the United States, owned and operated by American Transmission Company. It handles voltage levels of 138 kV and 69 kV, supporting regional grid stability.
Hillman Substation is an operational electrical substation located in the United States, specifically near coordinates 42.718747, -90.466324, which places it in the state of Wisconsin. Owned and operated by American Transmission Company (ATC), this facility plays a key role in the regional power grid. The substation operates at voltage levels of 138 kV and 69 kV, indicating it serves both transmission and sub-transmission functions, typical for facilities that connect bulk power systems to local distribution networks. As part of ATC's network, Hillman Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure reliability and security of the bulk power system. Its voltage levels suggest it is a medium-scale substation critical for maintaining grid stability in the region. The substation's location in a rural or semi-rural area of Wisconsin means it supports both local communities and potentially industrial loads. Its role in the transmission grid is essential for integrating generation sources and ensuring reliable electricity supply. The facility's operational status and ownership by a major transmission company underscore its importance in the regional electrical infrastructure.
Environmental context
The substation is situated in a region with a mix of agricultural and natural landscapes, typical of southwestern Wisconsin. Its operation involves electromagnetic fields and potential impacts on local wildlife, though modern substations are designed to minimize ecological disruption. The facility's voltage levels indicate it is part of the high-voltage transmission network, which can have visual and land-use implications. However, as a substation, its environmental footprint is generally limited compared to generation plants.
