Overview
Perry Willis Substation is an operational electrical substation in the United States, owned and operated by Alliant Energy. It operates at 161 kV, serving the regional grid.
Perry Willis Substation is an operational electrical substation located in the United States, owned and operated by Alliant Energy. The facility operates at a voltage of 161 kV, placing it in the medium-to-high voltage range typical for sub-transmission and distribution substations. It plays a key role in stepping down power from transmission lines to serve local distribution networks. As a substation in the United States, Perry Willis Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for the bulk power system, ensuring grid stability and security. The facility's 161 kV voltage level is common for regional power distribution, connecting higher-voltage transmission to lower-voltage distribution circuits. The substation is located in a rural area of Iowa, near Perry, and supports the electrical infrastructure for the surrounding community. Alliant Energy, the owner and operator, serves approximately 1 million electric customers across Iowa and Wisconsin. The substation contributes to the reliability of the local grid, facilitating the delivery of electricity to residential, commercial, and industrial users.
Environmental context
The substation is situated in a rural agricultural region of Iowa, where the local environment is characterized by farmland and open spaces. Electrical infrastructure in such areas typically has a lower environmental footprint compared to urban settings, though it may intersect with wildlife habitats. The 161 kV voltage level indicates a moderate scale of infrastructure, with standard measures in place to manage electromagnetic fields and prevent ecological disruption.
