Sunnyvale Substation: 115 kV Electrical Infrastructure in the United States

Sunnyvale is an operational electrical substation located in the United States, with coordinates 44.951191, -89.708867. The facility operates at a voltage of 115 kV, placing it within the medium-voltage range typical for distribution and sub-transmission networks. As a substation, it plays a critical role in stepping down high-voltage electricity for local distribution or interconnecting transmission lines. 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 the bulk power system. Facilities like Sunnyvale are essential for maintaining grid stability, especially in regions with varying demand and generation profiles. The 115 kV voltage level is commonly used for sub-transmission, serving industrial, commercial, and residential loads. Environmentally, the substation's location in a rural or suburban area of Wisconsin minimizes direct ecological impact, though its operation supports the integration of renewable energy sources and reduces transmission losses. The facility contributes to the reliability of the local grid, ensuring consistent power supply to surrounding communities and industries.

The substation's location in central Wisconsin places it in a region with a mix of agricultural and forested landscapes. Its 115 kV voltage level indicates a role in sub-transmission, which typically involves lower environmental footprint compared to high-voltage lines. The facility's operation supports grid stability and can facilitate the integration of distributed energy resources, such as wind and solar, which are increasingly prevalent in the area.
