Streator Substation is an operational electrical substation located in Illinois, United States. Owned and operated by Commonwealth Edison, the facility plays a key role in the regional power distribution network. As a 138 kV substation, it is part of the medium-voltage transmission infrastructure that connects generation sources to local distribution systems. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which set reliability standards for the bulk power system. Commonwealth Edison, a major utility in Illinois, ensures compliance with these standards to maintain grid stability. The facility's voltage level of 138 kV is typical for subtransmission substations that serve industrial and urban areas. Streator Substation contributes to the reliability of electricity supply in the region, supporting residential, commercial, and industrial customers. Its location in Illinois places it within the PJM Interconnection, one of the largest regional transmission organizations in the United States, which coordinates the movement of wholesale electricity across multiple states.
Environmental context
The substation is situated in a rural area near Streator, Illinois, surrounded by agricultural land and small communities. Its operation involves electromagnetic fields and potential oil leakage from transformers, which are managed through standard environmental safeguards. The facility's location away from densely populated areas reduces direct human exposure to electromagnetic fields, while its role in the grid supports efficient power transmission, minimizing line losses and associated environmental impacts.
