Silver Lake (ALTE) Substation - United States Electrical Infrastructure

Silver Lake (ALTE) is an operational electrical substation located in the United States, with coordinates 44.047434, -89.234048. The facility operates at a voltage level of 69 kV, which classifies it as a medium-voltage substation typical of sub-transmission or distribution networks. Substations at this voltage level are critical for stepping down power from high-voltage transmission lines to lower voltages for local distribution. In the United States, substations like Silver Lake (ALTE) operate under the regulatory framework of the North American Electric Reliability Corporation (NERC) and are subject to Federal Energy Regulatory Commission (FERC) oversight for reliability standards. The facility's voltage level suggests it serves a regional or local grid function, likely integrating with both transmission and distribution systems. The use of 69 kV is common in rural and suburban areas for efficient power delivery. Environmentally, the substation's location in a rural area of Wisconsin (based on coordinates) implies it supports agricultural or small community loads. Its operational status ensures continued reliability for the local grid. Substations at this voltage typically have a moderate environmental footprint, with considerations for oil containment from transformers and electromagnetic field management. The facility contributes to grid resilience by enabling power flow control and voltage regulation.

The substation is situated in a rural area of Wisconsin, where the surrounding landscape includes agricultural fields and natural habitats. Its 69 kV operation is typical for regional distribution, with environmental considerations including potential oil spill containment from transformers and electromagnetic field exposure limits. The facility's location away from dense urban centers reduces direct human exposure but requires careful siting to minimize impact on local ecosystems.
