Overview
Dupo Ferry Substation is an operational electrical substation in Missouri, United States, operated by Ameren Missouri. It operates at 138 kV, serving as a key node in the regional transmission grid.
Dupo Ferry Substation is an operational electrical substation located in Missouri, United States. Owned and operated by Ameren Missouri, the facility is part of the regional high-voltage transmission network, with a voltage level of 138 kV, which is typical for sub-transmission and distribution substations in the United States. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for the bulk power system. As a 138 kV facility, it plays a role in stepping down power from higher-voltage transmission lines for distribution to local communities, and its operation is subject to NERC's Critical Infrastructure Protection (CIP) standards. Located in the St. Louis metropolitan area, Dupo Ferry Substation supports grid stability and reliability for residential, commercial, and industrial customers in the region. Its strategic position within Ameren Missouri's network ensures efficient power delivery and contributes to the overall resilience of the Midcontinent Independent System Operator (MISO) grid.
Environmental context
The substation is situated in a mixed urban and suburban landscape near the Mississippi River, an area with significant industrial activity. Electrical infrastructure in this region must consider flood risks and soil stability, as well as proximity to sensitive ecosystems. The 138 kV voltage level indicates a moderate environmental footprint, with typical considerations for electromagnetic fields and stormwater management.
