Overview
St. John Substation is an operational electrical substation in the United States, handling voltages of 345 kV, 138 kV, and 69 kV, serving grid stability in the region.
St. John Substation is an operational electrical substation located in the United States, with coordinates 41.451161, -87.398893. It operates at multiple voltage levels including 345 kV, 138 kV, and 69 kV, indicating its role in both high-voltage transmission and sub-transmission. The facility is part of the broader North American power grid, which is regulated by NERC reliability standards and FERC oversight for transmission-level assets. The substation's voltage levels suggest it serves as a critical node in the regional electrical infrastructure, likely interconnecting major transmission lines and distributing power to local distribution networks. In the United States, substations of this scale are typically equipped with modern switchgear and automation systems compliant with ISO/IEC 61850 standards to ensure reliable operation and grid stability. Located in the Midwest, the substation supports the electrical needs of surrounding communities and industrial users. Its operational status and voltage configuration contribute to the resilience of the local grid, enabling efficient power flow and voltage regulation. The facility plays a key role in maintaining supply reliability in a region with diverse energy demands.
Environmental context
The substation's location in the Midwest United States places it within a region characterized by a mix of urban, suburban, and agricultural land uses. The facility's voltage levels and grid role influence local environmental considerations, such as electromagnetic field management and land use for transmission corridors. Its operation aligns with NERC standards for environmental compliance, including vegetation management and wildlife protection near power lines.
