Fox Lake Substation - 138 kV Electrical Infrastructure in Wisconsin, USA

Fox Lake is an operational electrical substation located in Wisconsin, United States. The facility operates at a voltage of 138 kV, placing it in the medium-to-high voltage range typical of sub-transmission and distribution substations. As part of the North American power grid, it supports local electricity distribution and grid reliability. The substation operates under the regulatory framework of the North American Electric Reliability Corporation (NERC) and the Federal Energy Regulatory Commission (FERC), which enforce reliability standards for bulk power systems. The 138 kV voltage level is common for sub-transmission networks that connect high-voltage transmission lines to lower-voltage distribution systems, serving industrial, commercial, and residential loads in the region. Fox Lake's location in rural Wisconsin contributes to its role in maintaining stable electricity supply for the surrounding area. Substations like this are critical for voltage regulation and fault isolation, ensuring reliable power delivery to end users. The facility's operational status indicates ongoing contribution to the regional electrical infrastructure.

The substation is situated in a rural area of Wisconsin, where the surrounding landscape includes agricultural fields and small water bodies. Electrical infrastructure in such settings typically has a low direct environmental footprint, though it supports the broader grid that powers local communities and industries. The 138 kV voltage level suggests the substation is part of the sub-transmission network, which often involves overhead lines that can affect bird flight patterns and require vegetation management to maintain clearances.
