Overview
St. Ansgar Substation is an operational electrical substation in Iowa, United States, owned and operated by Alliant Energy. It operates at a voltage of 69 kV, serving the local grid.
St. Ansgar Substation is an electrical substation located in Iowa, United States. Owned and operated by Alliant Energy, the facility is operational and plays a role in the regional power distribution network. The substation operates at a voltage of 69 kV, which is typical for sub-transmission and distribution-level infrastructure in the United States. As part of the U.S. electrical grid, St. Ansgar Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These standards ensure reliability and security for transmission and distribution assets. The substation likely includes switchgear and transformers to step down voltage for local distribution. The substation serves the community of St. Ansgar and surrounding areas, contributing to grid stability and electricity supply. Its location in rural Iowa underscores its role in connecting local distribution networks to the broader transmission system. Alliant Energy, a major utility in the Midwest, operates this facility as part of its commitment to reliable power delivery.
Environmental context
The substation is situated in a rural area of Iowa, where agricultural land use dominates. Electrical infrastructure in such settings typically has minimal direct environmental impact, though it supports the energy needs of farming communities. The 69 kV voltage level indicates a sub-transmission asset, which may involve overhead lines that can affect local wildlife and land use. Proper siting and maintenance practices help mitigate these effects.
