Overview
Spaulding Substation is an operational electrical substation in Illinois, United States, operated by Commonwealth Edison. It operates at 138 kV, serving the local power grid.
Spaulding Substation is an operational electrical substation located in Illinois, United States. Owned and operated by Commonwealth Edison, a major electric utility in the region, the facility plays a key role in the local power distribution network. The substation operates at a voltage of 138 kV, classifying it as a high-voltage substation that supports transmission and distribution functions. As part of the U.S. electrical infrastructure, Spaulding Substation operates under the regulatory framework established by the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for the bulk power system, ensuring grid stability and security. The 138 kV voltage level is common for subtransmission systems, linking larger transmission lines to distribution networks. The substation's location in Illinois places it within the PJM Interconnection, one of the largest regional transmission organizations in the United States. This interconnection coordinates the movement of electricity across multiple states, enhancing reliability and market efficiency. Spaulding Substation contributes to the resilience of the local grid, supporting residential, commercial, and industrial customers in the area.
Environmental context
The substation is situated in a suburban area of Illinois, characterized by a mix of residential and commercial development. The local environment includes woodlands and wetlands, which can be sensitive to electromagnetic fields and construction activities. Standard mitigation measures such as proper grounding and vegetation management are typically employed to minimize ecological impact.
