Overview
Marseilles Substation is an operational electrical substation in the United States, operating at 138 kV. It plays a key role in regional grid stability and power distribution.
Marseilles Substation is an operational electrical substation located in the United States, with coordinates 41.327147, -88.714997. The facility operates at a voltage of 138 kV, classifying it as a high-voltage substation critical for transmission and distribution within the regional power grid. 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 bulk power systems. As a 138 kV facility, it is typical of sub-transmission or distribution-level infrastructure that interconnects local grids with higher-voltage transmission networks. This substation supports the electrical infrastructure of the surrounding area, contributing to reliable power delivery for residential, commercial, and industrial consumers. Its operational status ensures continued grid stability and energy access in the region.
Environmental context
The substation is located in a rural area near Marseilles, Illinois, which is characterized by agricultural land and proximity to the Illinois River. The 138 kV voltage level indicates a moderate-scale facility that integrates with the regional grid. Environmental considerations for such substations include electromagnetic field management, oil containment for transformers, and habitat preservation around transmission corridors.
Frequently asked questions
Marseilles Substation is located in the United States, near Marseilles, Illinois, at coordinates 41.327147, -88.714997.
Marseilles Substation operates at 138 kV, a common voltage level for sub-transmission and distribution substations in the United States.
It is part of the US electrical grid and likely operated by a local utility or transmission company.
US substations must comply with NERC reliability standards and FERC regulations, which govern grid stability, maintenance, and cybersecurity for bulk power systems.
A 138 kV substation typically steps down voltage from higher transmission lines (e.g., 345 kV) for distribution to local networks, or interconnects generation sources to the grid, ensuring reliable power delivery.
