Polar Substation: 69 kV Electrical Infrastructure in the United States

Polar is a substation located in the United States, with coordinates 45.167288, -88.990674. It operates at a voltage of 69 kV, classifying it as a medium-voltage substation typical of distribution-level infrastructure. The facility is currently operational and plays a role in stepping down transmission voltages for local distribution. As a substation in the United States, Polar operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC). These bodies enforce reliability standards for the bulk power system, ensuring grid stability and security. The 69 kV voltage level is common for subtransmission systems that connect larger transmission networks to distribution feeders. The environmental context of Polar includes its location in a rural area of Wisconsin, where the substation supports local electricity distribution. Its operation contributes to grid reliability for surrounding communities and industrial users. The facility's age and specific equipment are not detailed, but typical substations of this voltage class use air-insulated or gas-insulated switchgear.

Located in a rural area of Wisconsin, Polar operates in a region with mixed forest and agricultural land use. The substation's 69 kV voltage level indicates it serves as a distribution node, potentially impacting local wildlife corridors through right-of-way maintenance. Electromagnetic fields from such infrastructure are regulated by state and federal guidelines to minimize ecological effects.
