Overview
Wolfs Crossing Substation is an operational electrical substation in the United States, owned and operated by Commonwealth Edison. It handles voltages of 345 kV and 138 kV, serving the local grid.
Wolfs Crossing Substation is an operational electrical substation located in the United States, owned and operated by Commonwealth Edison, a major utility in the region. The facility handles high-voltage transmission at 345 kV and sub-transmission at 138 kV, indicating its role in both long-distance power transfer and local distribution. 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. As part of the U.S. grid, it adheres to NERC's Critical Infrastructure Protection (CIP) standards and FERC's oversight of transmission assets. The dual voltage levels suggest it serves as a key node connecting transmission and distribution networks. Located near the Chicago metropolitan area, the substation supports the electrical infrastructure for a densely populated region with high energy demand. Its operational status ensures grid stability and reliability for residential, commercial, and industrial customers. The facility's role in the Commonwealth Edison network contributes to the overall resilience of the regional power system.
Environmental context
The substation is situated in an urbanizing area of Illinois, where land use transitions from agricultural to residential and commercial. Its operation involves electromagnetic fields and potential impacts on local wildlife, though modern substations are designed to minimize ecological disruption. The high voltage levels require careful siting to avoid interference with nearby communities and natural habitats.
Frequently asked questions
Wolfs Crossing Substation is located in the United States, near the Chicago metropolitan area in Illinois, at coordinates 41.707537, -88.232575.
The substation handles two voltage levels: 345 kV for high-voltage transmission and 138 kV for sub-transmission, serving both long-distance power transfer and local distribution.
The substation is owned and operated by Commonwealth Edison, a major electric utility serving northern Illinois.
In the United States, substations must comply with NERC reliability standards, including CIP for cybersecurity, and FERC regulations for transmission assets. These ensure grid stability and security.
A 345 kV substation is a critical node in the transmission network, stepping down voltage from extra-high-voltage lines to lower levels for distribution, and ensuring reliable power flow to large population centers.
