Overview
Green Lake Substation is an operational electrical substation in Illinois, United States, owned and operated by Commonwealth Edison. It operates at a voltage of 138 kV, serving the local grid.
Green Lake Substation is an operational electrical substation located in Illinois, United States. Owned and operated by Commonwealth Edison, a major utility in the region, the substation plays a key role in the local electrical infrastructure. With a voltage level of 138 kV, it is classified as a high-voltage substation, typical for transmission and distribution networks in the United States. 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. Commonwealth Edison, as the operator, adheres to these standards to ensure grid stability and safety. The 138 kV voltage level indicates that this substation likely serves as a distribution substation, stepping down power from higher transmission voltages for local distribution. As part of the Commonwealth Edison network, Green Lake Substation contributes to the reliable supply of electricity to residential, commercial, and industrial customers in the region. Its operational status ensures continued support for the local grid, which is critical for economic activity and community well-being. The substation's location in Illinois places it within a state with a diverse energy mix, including nuclear, coal, and renewable sources.
Environmental context
The substation's location in Illinois is characterized by a mix of urban and rural areas, with the local grid supporting a variety of end-users. The environmental impact of substations is generally limited to electromagnetic fields and land use, but modern designs incorporate measures to minimize ecological disruption. The 138 kV voltage level is typical for distribution substations, which are often situated in populated areas to reduce transmission losses.
