Overview
Stone City Substation is an operational electrical substation in Iowa, United States, owned and operated by Maquoketa Valley REC. It handles voltages of 69 kV and 12.5 kV, serving the local grid.
Stone City Substation is an electrical substation located in Iowa, United States, owned and operated by Maquoketa Valley REC. The facility is operational and plays a role in the regional power distribution network, typical of rural electric cooperatives in the Midwest. The substation operates at voltage levels of 69 kV and 12.5 kV, indicating it serves as a step-down point from transmission to distribution. As part of the U.S. electrical infrastructure, it falls under the reliability standards set by NERC and is subject to FERC regulation for interstate power flows. The facility's design likely incorporates standard substation automation protocols such as IEC 61850 for efficient monitoring and control. Stone City Substation contributes to grid stability in the Maquoketa Valley area by ensuring reliable electricity delivery to rural communities. Its operation supports the local agricultural and residential loads, and it is part of the broader interconnected power system that enhances energy security in the region.
Environmental context
The substation is located in a rural area of Iowa, characterized by agricultural land and dispersed residential communities. Its operation involves electromagnetic fields and potential oil containment from transformers, which are managed under environmental regulations. The site's proximity to natural habitats may require mitigation measures to protect local wildlife, though specific designations are not confirmed.
