Overview
Marshall Substation is an operational 138 kV substation owned by Ameren Missouri in the United States. It plays a key role in regional grid stability and power distribution.
Marshall Substation is an operational electrical substation located in the United States, owned and operated by Ameren Missouri. The facility operates at a voltage level of 138 kV, placing it within the sub-transmission to transmission range, typical for distributing power from high-voltage transmission lines to local distribution networks. As part of the U.S. electrical infrastructure, Marshall Substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) reliability standards and Federal Energy Regulatory Commission (FERC) oversight for transmission-level assets. The 138 kV voltage class is commonly used for regional power delivery, connecting bulk transmission systems to substations serving industrial, commercial, and residential areas. The substation's location in Missouri supports the regional grid managed by the Midcontinent Independent System Operator (MISO), ensuring reliable electricity supply. Its operational status and ownership by a major utility like Ameren Missouri underscore its importance in maintaining grid stability and meeting local energy demands.
Environmental context
The substation is situated in a temperate climate zone typical of the Midwestern United States, where seasonal temperature variations influence electricity demand. Its urban or suburban setting likely requires careful management of electromagnetic fields and noise, though no specific environmental designations are confirmed. The facility's role in power distribution supports local communities and industries, contributing to regional economic activity.
