Overview
Fort Madison Devils Creek is a 69 kV substation in Iowa, United States, operated by Alliant Energy. It plays a role in regional grid stability and power distribution.
Fort Madison Devils Creek is a substation located in Iowa, United States, operated by Alliant Energy. The facility operates at 69 kV, a voltage level typical for sub-transmission and distribution substations that serve local communities and industrial areas. As part of the broader electrical infrastructure, it contributes to the reliability of the regional power grid. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards and FERC oversight for transmission-level assets. While 69 kV is below the typical threshold for NERC's bulk electric system (100 kV), it is still subject to state-level utility regulations and reliability coordination. Substations of this voltage class commonly use air-insulated switchgear and are designed for long service life. Fort Madison Devils Creek substation supports the electrical needs of the surrounding area, including residential, commercial, and possibly industrial customers. Its location in Iowa places it within the Midcontinent Independent System Operator (MISO) region, which manages the grid and ensures reliable electricity supply. The substation's operational status and connection to the wider transmission network underscore its importance in maintaining local power delivery.
Environmental context
The substation is located in a rural area near Fort Madison, Iowa, with the surrounding landscape primarily agricultural. Substations of this type have minimal direct environmental impact, though they require vegetation management and may involve transformer oil containment. The 69 kV voltage level indicates a sub-transmission role, connecting higher-voltage lines to local distribution networks. Typical substations in this region are designed to withstand local weather conditions, including storms and temperature extremes.
Frequently asked questions
Fort Madison Devils Creek substation is located in Iowa, United States, near the city of Fort Madison. Its coordinates are approximately 40.580970 N, -91.430861 W.
Fort Madison Devils Creek substation operates at 69 kV (69,000 volts), which is a common voltage for sub-transmission and distribution substations.
Fort Madison Devils Creek substation is operated by Alliant Energy, a utility company serving customers in the Midwest United States.
In the United States, substations are subject to NERC reliability standards for assets above 100 kV, but lower-voltage facilities like this 69 kV substation are regulated by state utility commissions and must comply with local grid codes and safety standards.
A 69 kV substation typically serves as a sub-transmission facility, stepping down voltage from higher transmission lines (e.g., 138 kV or 230 kV) to distribution levels (e.g., 12 kV or 34.5 kV) for local power delivery to homes and businesses.
