Overview
Elmwood Substation is an operational electrical substation in Illinois, United States, owned by Commonwealth Edison. It operates at 138 kV, serving the local grid.
Elmwood Substation is an operational electrical substation located in Illinois, United States. Owned by Commonwealth Edison, a major utility in the region, this facility plays a key role in the local electrical infrastructure. The substation operates at a voltage of 138 kV, which is typical for sub-transmission and distribution-level assets in the United States. As part of the Commonwealth Edison network, Elmwood Substation is subject to regulatory oversight by the Federal Energy Regulatory Commission (FERC) and must comply with North American Electric Reliability Corporation (NERC) reliability standards. These standards ensure grid stability and security, particularly for assets operating at transmission-level voltages. The substation likely employs modern switchgear and automation systems to maintain reliable power flow. Elmwood Substation contributes to the electrical supply for the surrounding community, supporting residential, commercial, and industrial loads. Its operational status ensures continued grid connectivity and power distribution. The facility's location in Illinois places it within a region with a diverse energy mix, including nuclear, coal, and renewable sources, highlighting its role in integrating various generation sources into the grid.
Environmental context
The substation is located in a suburban area of Illinois, where electrical infrastructure must balance reliability with environmental considerations. Urban and suburban substations like Elmwood often incorporate noise mitigation and oil containment systems to minimize local impact. The 138 kV voltage level indicates a role in distributing power from transmission lines to local distribution networks, with potential electromagnetic field considerations managed through standard siting practices.
