Overview
MEARS CORNERS is an operational electrical substation in the United States, handling voltages of 138 kV and 24.9 kV. It plays a role in regional grid stability and power distribution.
MEARS CORNERS is an operational electrical substation located in the United States, with coordinates 44.111392, -88.545804. The facility operates at voltage levels of 138,000 volts and 24,900 volts, indicating its role in both transmission and distribution within the electrical grid. As a substation, it serves as a critical node for stepping down high-voltage electricity for local distribution. The substation operates under the regulatory framework of the United States, which includes NERC reliability standards and FERC oversight for transmission-level assets. The 138 kV voltage level classifies it as a sub-transmission or transmission asset, subject to reliability standards and grid interconnection requirements. The 24.9 kV side suggests distribution to industrial or large commercial customers. Located in Wisconsin, the substation supports the regional grid operated by the Midcontinent Independent System Operator (MISO). Its operational status ensures continued reliability for the surrounding area. The facility's design and equipment likely adhere to ISO/IEC 61850 standards for substation automation, enhancing monitoring and control capabilities.
Environmental context
The substation is situated in a region with a mix of urban and rural areas, typical of Wisconsin's landscape. Its operation involves electromagnetic fields and potential impacts on local wildlife, though modern substations are designed to minimize ecological disruption. The facility's location near water bodies may require stormwater management to prevent runoff contamination. Vegetation management around the substation is necessary to maintain clearance and prevent outages.
