Overview
Spragueville Substation is an operational electrical substation in Iowa, United States, operated by Maquoketa Valley REC. It operates at 69 kV, serving the local grid.
Spragueville Substation is an operational electrical substation located in Iowa, United States. Operated by Maquoketa Valley REC, the facility plays a role in the regional electrical infrastructure, stepping down transmission voltages for local distribution. The substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level infrastructure in the United States. As part of the Maquoketa Valley REC network, it is subject to reliability standards set by the North American Electric Reliability Corporation (NERC) and oversight by state regulatory bodies. The facility's equipment likely includes circuit breakers, transformers, and switchgear designed to ensure stable power flow. As a substation in a rural area of Iowa, Spragueville Substation supports agricultural and residential electricity needs. Its operational status ensures continued grid stability and power delivery to the surrounding community. The facility contributes to the resilience of the local electrical network, which is essential for economic activities and daily life.
Environmental context
The substation is located in a rural area of Iowa, where the surrounding landscape is primarily agricultural. Electrical infrastructure in such settings must consider land use compatibility and potential impacts on local wildlife. The 69 kV voltage level indicates a sub-transmission role, with lower electromagnetic field exposure compared to higher voltage lines. Vegetation management around the substation is typical to maintain clearance and prevent outages.
Frequently asked questions
Spragueville Substation is located in Iowa, United States, near coordinates 42.1056, -90.4483.
Spragueville Substation operates at a voltage of 69 kV, which is typical for sub-transmission or distribution-level substations.
Spragueville Substation is operated by Maquoketa Valley REC, a rural electric cooperative in Iowa.
Substations in the United States must comply with NERC reliability standards for grid stability, and may also be subject to FERC regulations for transmission-level assets. State public utility commissions oversee local distribution.
A 69 kV substation typically steps down transmission voltages (e.g., 138 kV or higher) to distribution levels (e.g., 12 kV or 34.5 kV) for local delivery to homes and businesses.
