Rock Creek Substation: ITC-Owned Electrical Substation in the United States

Rock Creek Substation is an operational electrical substation located in the United States, owned and operated by ITC. The facility plays a key role in the regional transmission network, handling multiple voltage levels that support reliable electricity distribution. The substation operates at voltages of 345 kV, 161 kV, and 69 kV, indicating its function as a major transmission node. As part of the U.S. electrical infrastructure, it falls under NERC reliability standards and FERC regulation, ensuring compliance with grid stability and security requirements. The facility's location in the Midwest aligns with typical substation configurations for bulk power transfer. This substation contributes to the resilience of the local grid by interconnecting high-voltage transmission lines. Its operational status and voltage diversity underscore its importance in maintaining continuous power supply to surrounding communities and industries. The facility's role in the ITC network supports regional energy reliability and economic activity.

The substation is situated in a rural area of Iowa, where agricultural land dominates the landscape. Its operation involves electromagnetic fields and potential oil leakage from transformers, but modern containment measures mitigate environmental impact. The site's distance from urban centers reduces exposure to sensitive receptors, while its voltage levels indicate significant power throughput that supports regional energy needs without direct emissions.
