Overview
Tollway Electrical Substation is an operational substation in the United States, operating at 138 kV. It plays a role in regional grid stability and power distribution.
Tollway Electrical Substation is a substation located in the United States, with coordinates 41.805329, -88.147742. It is classified under the Electrical Infrastructure sector and is currently operational. The facility operates at a voltage level of 138 kV, which is typical for sub-transmission and distribution substations in the US grid. 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 a 138 kV facility, it likely serves as a distribution substation stepping down from higher transmission voltages or interconnecting local distribution networks. Such substations are critical for maintaining grid reliability and power quality in their service areas. The environmental context of this substation includes its location in a suburban or urban area near Chicago, Illinois. Substations at this voltage level are typically designed with oil-filled transformers and switchgear, which require proper containment and fire protection measures. The facility's operational status and voltage level indicate it is an active component of the regional electrical infrastructure, supporting local residential, commercial, and industrial loads.
Environmental context
The substation is located in a suburban area near Chicago, Illinois, where electrical infrastructure is integrated into a densely populated region. At 138 kV, the facility likely uses oil-filled transformers, which require spill containment and fire suppression systems to mitigate environmental risks. The site's proximity to residential and commercial zones necessitates compliance with local noise and electromagnetic field regulations.
