ComEd - TSS198 Des Plaines is a substation located in Des Plaines, Illinois, United States. It is owned and operated by Commonwealth Edison (ComEd), a major electric utility serving northern Illinois. The facility operates at 138 kV, a common transmission voltage level that connects local distribution networks to the broader grid. As a 138 kV substation, TSS198 Des Plaines is part of ComEd's extensive transmission infrastructure, which is regulated by the Federal Energy Regulatory Commission (FERC) and subject to North American Electric Reliability Corporation (NERC) reliability standards. Substations at this voltage level typically serve as critical nodes for stepping down power from higher transmission voltages to distribution levels, ensuring stable electricity supply to residential, commercial, and industrial customers in the Des Plaines area. The substation's location in a suburban area near Chicago places it within a densely populated region with high electricity demand. Its operational status contributes to grid reliability and resilience, supporting the local community's energy needs. The facility's age and specific equipment details are not publicly available, but its continued operation underscores its importance to the regional electrical infrastructure.
Environmental context
The substation is situated in Des Plaines, a suburban city in northeastern Illinois with a temperate climate. The area experiences seasonal temperature extremes, which can affect electricity demand for heating and cooling. The facility's 138 kV voltage level indicates it is part of the transmission network, which has a moderate environmental footprint primarily related to land use and electromagnetic fields. Its urban location means it is integrated into existing infrastructure, minimizing additional habitat disruption.
