Overview
Wilmington Substation is an operational electrical substation in Wilmington, United States, operating at 138 kV. It plays a key role in regional grid stability and power distribution.
Wilmington Substation is an operational electrical substation located in Wilmington, United States. It operates at a voltage of 138 kV, classifying it as a high-voltage substation critical for transmitting electricity from generation sources to distribution networks. The facility is part of the broader US electrical infrastructure, which is regulated by NERC reliability standards and FERC oversight for transmission-level assets. The substation's 138 kV voltage level indicates it serves as a transmission or sub-transmission node, likely interconnecting local distribution systems with higher-voltage bulk power lines. In the US, such substations are essential for maintaining grid reliability and are subject to NERC's Critical Infrastructure Protection (CIP) standards. The facility's location in Wilmington, Illinois, places it within the Midcontinent Independent System Operator (MISO) region, which manages grid operations across multiple states. Wilmington Substation contributes to the electrical supply for the surrounding community and industrial areas. Its operational status ensures continued support for local power needs, including residential, commercial, and potential industrial loads. The substation's role in voltage regulation and power flow control is vital for preventing outages and maintaining system stability in the region.
Environmental context
The substation is located in Wilmington, Illinois, a rural area with agricultural land and small communities. Electrical infrastructure in such settings typically has lower environmental impact than urban facilities, but still requires careful management of electromagnetic fields, oil containment for transformers, and vegetation clearance to prevent outages. The 138 kV voltage level is moderate, reducing the risk of corona discharge and associated ozone production compared to higher-voltage lines.
Frequently asked questions
Wilmington Substation is located in Wilmington, Illinois, United States, at coordinates 41.292461, -88.178937.
Wilmington Substation operates at 138 kV, a common voltage level for transmission and sub-transmission substations in the United States.
Typically, substations in the US are operated by investor-owned utilities, cooperatives, or public power entities.
As part of the US electrical grid, Wilmington Substation must comply with NERC reliability standards, including CIP for cybersecurity, and FERC regulations for transmission assets. It likely falls under MISO's regional oversight.
A 138 kV substation steps down high-voltage transmission power for local distribution or interconnects sub-transmission lines. It helps regulate voltage, protect circuits, and ensure reliable electricity supply to communities.
