Sherrill Substation - 69 kV Substation in Iowa, United States

Sherrill Substation is an operational electrical substation located in Iowa, United States. It is owned and operated by Maquoketa Valley REC, a rural electric cooperative. The substation operates at a voltage of 69 kV, which is typical for distribution-level infrastructure in rural areas. As a substation in the United States, Sherrill Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for the bulk power system. The facility's 69 kV voltage level places it in the sub-transmission or distribution category, supporting local power distribution to residential and commercial customers. The substation plays a key role in the electrical infrastructure of the region, ensuring stable power supply to the surrounding community. Its operation by a rural electric cooperative highlights its importance in serving rural areas where reliability is critical for agricultural and residential needs.

The substation is located in a rural area of Iowa, where the landscape is primarily agricultural. Electrical infrastructure in such settings must balance reliability with minimal environmental impact, often involving careful siting to avoid sensitive habitats. The 69 kV voltage level indicates a distribution role, which typically has lower environmental footprint compared to high-voltage transmission lines.
